Standard recommendations for fast-track hip arthroplasty suggest using 8-10 mg of dexamethasone to reduce opioid consumption, with potential benefits of higher doses but scarce data on glycaemic control and complications. This study compares the effects of higher doses versus the standard doses on postoperative opioid consumption, and secondarily, numerical pain scale, glycaemic control, hospital length of stay and postoperative complications.

Retrospective cohort study of patients scheduled for FAST-TRACK primary hip arthroplasty between 2016 and 2021. Propensity score-matched analyses compared the standard dose group (4-8 mg) versus the high-dose group (16-24 mg).

168 patients were included (56 with 4-8 mg, 112 with 16-24 mg). After one-to-one propensity score matching, 52 patients were included in the standard group and 52 in the high-dose group. After matching, the median [IQR] opioid consumption in the low-dose group was 10 [0-12] and in the high-dose group was 0 [0-10], with a 95% CI of -1 to 0 (p = 0.016). In the matched group, there was a median difference of 8 mg/dL (95% CI, -2 to 7, P < 0.05) in the immediate postoperative glycaemia, of 17 mg/dl (95% CI, -2 to 14, P < 0.05) in glycaemia at 24 h and of -1 day (95% CI, -1 to 0, P < 0.05) in hospital stay. No differences in the numerical pain scale and postoperative complications were found.

High-dose dexamethasone slightly increased perioperative glycaemia while reducing opioid consumption and shortening hospital length of stay.

Head and neck cancer (HNC) remains a major global health issue. It is closely linked to smoking, alcohol use, and HPV infection. Nutritional and metabolic factors significantly influence surgical outcomes in these patients, especially when undergoing extensive resections and microsurgical free flap reconstruction. This comprehensive review aims to evaluate how perioperative nutritional status-particularly body mass index (BMI), serum albumin and prealbumin levels, and enteral vs. oral feeding strategies-affects complication rates, wound healing, surgical duration, and overall recovery. Poor nutritional status is associated with increased complication rates, prolonged surgery, impaired wound healing, and higher perioperative mortality. Both high and low BMI negatively impact surgical outcomes. Obesity is linked to protracted surgery and increased blood loss, while underweight patients have higher perioperative mortality. Optimizing perioperative nutrition is important for improving surgical outcomes in HNC patients. A multidisciplinary approach is necessary to tailor nutritional support and enhance recovery. Further research should focus on long-term weight management strategies and identifying biomarkers predictive of surgical success.

Maintaining optimal glucose control is critical for postoperative care cardiac surgery patients. Continuous glucose monitoring (CGM) in this setting remains understudied. We evaluated the efficacy of CGM with a specialized titration protocol in cardiac surgery patients with type 2 diabetes (T2D) and prediabetes.

In this randomized-controlled trial, 54 cardiac surgery patients were randomized one day post-surgery, with 27 CGM and 25 point-of-care (POC) patients completing the study. The CGM group used Dexcom G6 with a CGM-specialized titration protocol, while the POC group used standard monitoring with blinded CGM. The primary outcome was time-in-range (TIR) 100-180 mg/dL for 7 days post-surgery. Secondary outcomes included various glycemic metrics and surgical outcomes. Multiple comparison adjustments were performed using false-discovery-rate (FDR).

Thirty-one (59.6%) had diabetes and 21 (40.4%) had prediabetes. While TIR 100-180 mg/dL showed no difference (74.7% vs. 71.6%, FDR-adjusted p = 0.376), the CGM group demonstrated improvements in TIR 70-180 mg/dL (83.8% vs. 75.8%, FDR-adjusted p = 0.026), time-in-tight-range (TITR) 100-140 mg/dL (46.3% vs. 36.3%, FDR-adjusted p = 0.018), and TITR 70-140 mg/dL (55.3% vs. 40.5%, FDR-adjusted p = 0.003). Both groups maintained very low rates of time below range (< 70 mg/dL: 0.03% vs. 0.18%, FDR-adjusted p = 0.109). The CGM group showed lower postoperative atrial fibrillation (AF) (18.8% vs. 55.6%, FDR-adjusted p = 0.04999).

While the primary outcome was not achieved, CGM with a specialized titration protocol demonstrated safe glycemic control with improvements in TIR 70-180 mg/dL and TITRs in cardiac surgery patients with T2D and prediabetes. The observed reduction in postoperative AF warrants further investigation.

Perioperative management in diabetic patients is important since their postoperative mortality and morbidity are higher than that of non-diabetic patients, which will exacerbate the burden on public health. We selected relevant publications from the WoSCC-SCIE between 2007 and 2024, utilizing VOSviewer and CiteSpace to analyze the collected information and generate knowledge maps. A total of 3167 articles from 792 journals and 83 countries/regions were included for analysis. Overall, there has been a continuous increase in publication volume. From the result of academic collaboration between different countries/regions and institutions, the USA occupies a central position in research strength. A total of 18,101 authors participated in research on "perioperative management in diabetic patients" with Dr. Guillermo E. Umpierrez from Emory University School of Medicine being the most productive author. We conclude that perioperative adverse clinical outcomes in diabetic patients and perioperative blood glucose management have consistently been research hotspots in this field. Additionally, continuous glucose monitoring and insulin administration under computer guidance, as well as the use of merging medications are likely to be frontier directions for future research. Research on perioperative care for diabetic patients has been further deepened worldwide, which will be crucial in further improving perioperative care for diabetic patients and enhancing postoperative recovery.

The effectiveness of preoperative carbohydrate loading(PCL) on postoperative insulin resistance(IR) is controversial. In addition, the effect of different doses of carbohydrates on postoperative IR is also controversial. Therefore, this study aimed to investigate the efficiency of PCL on postoperative IR and the optimal regimen for the effect on postoperative IR.

A systematic search of clinical randomized controlled trials was performed to extract basic information about the included studies, specific regimens of PCL, and preoperative and postoperative IR. Network meta-analysis was performed using frequentist random effects. A total of 7 regimens were identified by categorizing them based on frequency, timing, control groups, and conducting subgroup analysis according to surgical procedure. High (>45 g) and low (≤45 g) doses were divided according to the standard definition of PCL. Dose analysis was performed on studies in the subgroups that met the optimal frequency and timing regimen. Reporting of results based on weighted mean differences(WMD), 95 % confidence intervals(95%CrI), and the surface under the cumulative ranking(SUCRA).

Carbohydrate loading given only 3 h before surgery is more strongly associated with insulin resistance than fasting(WMD: -4.04,95%CrI: -5.67 to -2.40) and placebo(WMD: -4.00,95%CrI: -5.98 to -2.02). Single-dose preoperative 3 h regimen has the highest probability of being the optimal regimen(SUCRA = 90.9 %). This is also true in open(SUCRA = 93.7 %) and laparoscopic surgery(SUCRA = 99.9 %). Analyzed using a fixed-effects model in open and laparoscopic surgery. In open surgery, high-dose and low-dose carbohydrates are associated with postoperative IR compared with fasting(high-dose: WMD: -1.75,95%CrI: -1.95 to -1.54; low-dose: WMD: -2.46,95%CrI: -3.70 to -1.23) and placebo(high-dose: WMD: -5.37,95%CrI: -6.99 to -3.76; low-dose: WMD: -6.09,95%CrI: -7.29 to -4.90). Low-dose carbohydrates(SUCRA = 95.3 %) have the highest probability of being the best option. In laparoscopic surgery, high-dose and low-dose carbohydrates are also associated with postoperative IR compared with fasting(high-dose (WMD: -5.70,95 %, CrI: -7.63 to -3.77); low-dose (WMD: -3.69,95%CrI: -4.11 to -3.27))and placebo(high-dose (WMD: -5.73,95%CrI: -7.72 to -3.74); low-dose (WMD: -3.72,95%CrI: -4.14 to -3.30)). SUCRA for high-dose carbohydrates is 99.2 %.

Preoperative implementation of carbohydrate loading is more beneficial in alleviating postoperative insulin resistance than fasting and placebo. Conducting PCL on the morning of surgery is more effective in relieving postoperative IR. For both open and laparoscopic surgeries, administering carbohydrate loading 3 h before the surgery may represent the optimal regimen. Further studies are needed to investigate the effect of different doses on postoperative IR.

To provide recommendations on risk mitigation, diagnosis and treatment of infectious complications associated with the practice of regional anesthesia, acute and chronic pain management.

Following board approval, in 2020 the American Society of Regional Anesthesia and Pain Medicine (ASRA Pain Medicine) commissioned evidence-based guidelines for best practices for infection control. More than 80 research questions were developed and literature searches undertaken by assigned working groups comprising four to five members. Modified US Preventive Services Task Force criteria were used to determine levels of evidence and certainty. Using a modified Delphi method, >50% agreement was needed to accept a recommendation for author review, and >75% agreement for a recommendation to be accepted. The ASRA Pain Medicine Board of Directors reviewed and approved the final guidelines.

After documenting the incidence and infectious complications associated with regional anesthesia and interventional pain procedures including implanted devices, we made recommendations regarding the role of the anesthesiologist and pain physician in infection control, preoperative patient risk factors and management, sterile technique, equipment use and maintenance, healthcare setting (office, hospital, operating room), surgical technique, postoperative risk reduction, and infection symptoms, diagnosis, and treatment. Consensus recommendations were based on risks associated with different settings and procedures, and keeping in mind each patient's unique characteristics.

The recommendations are intended to be multidisciplinary guidelines for clinical care and clinical decision-making in the regional anesthesia and chronic interventional pain practice. The issues addressed are constantly evolving, therefore, consistent updating will be required.

Around 9 million people live with diabetes mellitus (DM) in Germany. Around 500,000 new cases are documented every year. In addition, it must be assumed that there are at least 2 million unreported cases. The proportion of patients with type 2 DM is by far the highest and it is currently estimated that around 340,000 adults and 32,000 children are affected by type 1 DM [1]. People with diabetes have an increased mortality rate; however, this has decreased in recent years, particularly due to a reduction in cardiovascular mortality. "New" antidiabetic drugs have certainly played a relevant role in this. Various studies have shown that sodium-glucose Cotransporter 2 inhibitors (SGLT2 inhibitors) in particular but also glucagon-like peptide‑1 receptor agonists (GLP1-RA), have a significant benefit in patients with heart failure [2-5]. Surprisingly, this effect was also detectable in patients without DM [6]. Thus, the group of people who are treated with an SGLT2 inhibitor or a GLP1-RA has been expanded to include people who suffer from heart failure not associated with diabetes. This applies both to patients with reduced left ventricular systolic function (heart failure with reduced ejection fraction, HFrEF) and with preserved or mildly reduced systolic function (heart failure with preserved/mildly reduced ejection fraction, HFpEF/HFmrEF) [7]. In Germany heart failure is the most common diagnosis for hospitalization (40.6 cases/10,000 insurance years) and diseases of the cardiovascular system are the most common cause of death [8]. The increased risk of morbidity and mortality is also reflected in the perioperative setting.In addition to the risks posed by DM itself or associated diseases, the treatment with antidiabetic drugs can also lead to perioperative complications. This article focuses on the drug-related risks of the "new" antidiabetic drugs and draws conclusions regarding the management of anesthesia. The potentially life-threatening euglycemic diabetic ketoacidosis (eDKA) can be a perioperative side effect of SGLT2 inhibitors; however, the diagnosis is associated with hurdles. The GLP1-RAs are also increasingly being prescribed as they reduce cardiovascular risk and make weight loss much easier. GLP1-RAs delay gastric emptying, which potentially results in an increased risk of aspiration. In particular, if other risk factors for aspiration exist, patients should not be considered fasting, if the recommended break in GLP1‑RA intake has not been followed.

To evaluate whether preoperative glycemic control is predictive of acute endophthalmitis after cataract surgery.

Retrospective case-control study.

Patients with diabetes mellitus (DM) who underwent cataract surgery from 2010 through 2022 in the United States Veterans Affairs (VA) Health Care System.

Data extracted from the VA Corporate Data Warehouse included patient demographics, clinical features, timing of DM diagnosis, and preoperative hemoglobin A1c (HbA1c) levels drawn 0 to 6 months before surgery. Patients with acute postoperative endophthalmitis were identified using Current Procedural Terminology and International Classification of Diseases codes, then confirmed by chart review. Univariable and multivariable analyses were used to test for an association between preoperative HbA1c and the development of postoperative endophthalmitis.

Development of postoperative endophthalmitis within 42 days after cataract surgery.

Of 190 393 patients with a diagnosis of DM at the time of cataract surgery and HbA1c recorded 0 to 6 months before surgery, 157 patients (0.08%) demonstrated acute postoperative endophthalmitis. Mean ± standard deviation preoperative HbA1c was lower in patients with acute postoperative endophthalmitis (7.1 ± 1.4%) than in control participants without endophthalmitis (7.3 ± 1.5%), but this difference was not significant (P = 0.14). Similarly, subanalysis of the cohort with HbA1c levels drawn 0 to 2 months before surgery showed no association between preoperative HbA1c and endophthalmitis (P = 0.31). Multiple logistic regression analysis also showed no association between preoperative glycemic control as measured by HbA1c and postoperative endophthalmitis (adjusted odds ratio, 0.89; 95% confidence interval, 0.79-1.01; P = 0.08).

Preoperative HbA1c level was not associated with the development of acute postoperative endophthalmitis in patients with DM undergoing cataract surgery. These findings suggest that preoperative HbA1c guidelines based on infection rates after nonophthalmic surgery may not apply to cataract surgery.

Enhanced Recovery After Surgery (ERAS) protocols are used in elective colorectal surgeries and have shown improved recovery for many patients. However, using these protocols in emergency colorectal surgery, especially in complicated cases of obstructive colorectal cancer, is still debated. This review examined the ERAS principles that can be adapted for emergencies. We reviewed the literature on applying ERAS principles in emergency colorectal cancer surgery. We analyzed key strategies used before, during, and after surgery. The aim of ERAS in emergency colorectal surgery is to reduce physical stress from urgent surgical conditions. Before surgery, the focus should be on early patient recovery, managing blood sugar levels, and providing patient education when possible. Minimally invasive techniques, careful fluid management, and effective pain relief during surgery are intraoperative key points. After surgery, early feeding, patient mobilization, and minimizing the use of medical devices are encouraged. Studies have shown that using ERAS in emergencies can lower mortality, reduce hospital stays, and influence patient recovery rates, although it may lead to higher initial costs. Still, following ERAS in emergencies is inconsistent due to logistical issues and patient health changes. More people are starting to recognize the benefits of ERAS in obstructive colorectal cancer surgery. Although there is less evidence compared to elective procedures, new studies suggest that organized steps for care can improve patient outcomes. Further research is needed to improve ERAS emergency protocols and identify patients suitable for this approach so that healthcare resources can be used better.

This study aimed to reveal the effects of a glycemic control protocol directed by nurses during the perioperative period on glycemic outcomes in diabetic patients undergoing major abdominal surgery.

This was a prospective cohort study METHODS: The study was conducted at the Department of General Surgery of a research and training hospital in Turkey. The study included 47 patients with type 2 diabetes mellitus who underwent elective major abdominal surgery between September 2017 and December 2018. The number of patients in the intervention and the control groups was 22 and 25, respectively. Routine clinical glycemic control was implemented in the control group, whereas a glycemic management protocol developed by a multidisciplinary team was implemented in the intervention group. We collected data on the control group first, followed by the introduction of the glycemic management protocol to clinical staff and glycemia data collection using the new protocol. Blood glucose (BG) levels in patients and the factors that may affect BG were measured in the preoperative, intraoperative, and postoperative periods. Data on glycemic control was also collected. Furthermore, we measured the satisfaction of the nurses implementing the glycemic management protocol.

The rate of hyperglycemia in intensive care unit was 21% in the intervention group and 59% in the control group (P < .05). Time spent in the target BG range during insulin infusion was 76% in the intervention group and 35% in the control group (P < .05). The time required to achieve target BG range during insulin infusion was 6 hours for the intervention group and 15 hours for the control group, indicating that less time was required to achieve the target BG range in the intervention group (P < .05). Moreover, the insulin consumption rate in the intensive care unit was lower in the intervention group (P < .05). The satisfaction levels of the nurses that used the glycemic management protocol was 92.61 ± 7.93%.

Results of this study showed that the implementation of a glycemic management protocol by nurses for patients undergoing major abdominal surgery decreases the rate of hyperglycemia, insulin consumption rate, and the time required to achieve the targeted BG range during the perioperative period. Therefore, it is recommended to use a glycemia management protocol to control glycemia in patients during the surgical process.

The integration of procedure-specific risks into preoperative patient assessment and optimization are crucial aspects of perioperative care. However, data on internists' knowledge of surgical and anesthetic principles and practices are limited. We thus sought to identify internists' knowledge gaps in terms of surgical- and anesthetic-specific risk factors and characteristics.

An open and voluntary e-survey was conducted via LimeSurvey between April and July 2021 to evaluate Canadian internists' knowledge of surgical and anesthetic principles and practices. The survey included the perceived importance and knowledge of several key surgical and anesthetic aspects, such as surgery duration, procedure-specific cardiac risk, bleeding risk, and thrombotic risk. It also assessed pre- and post-survey self-reported confidence levels in one's knowledge of these characteristics. Finally, we investigated how internists optimize some of the preoperative risks.

A total of 173 Canadian internists opened the survey link, and 121 completed it (completion rate 70%). While the majority of respondents considered surgical and anesthetic principles and practices as important, most identified knowledge gaps. Participants generally estimated surgery duration and procedure-specific cardiac risk adequately. However, they tended to underestimate procedure-specific bleeding risk for general (58%) and orthopedic (76%) surgeries and to overestimate procedure-specific thrombotic risk for vascular (63%) and genitourinary (60%) surgeries. Furthermore, there is a lack of consensus regarding the appropriate hemoglobin A1c target and 0% of respondents reported using the guideline-suggested hemoglobin threshold for investigation and intervention.

Overall, our findings identify significant knowledge gaps among Canadian internists in preoperative assessment of procedure-specific risk factors and can be used to inform both the development of educational initiatives and future research to improve the quality of preoperative patient care.

The increasing prevalence of diabetes mellitus has been accompanied by a rapid expansion in wearable continuous glucose monitoring (CGM) devices and insulin pumps. Systems combining these components in a "closed loop," where interstitial glucose measurement guides automated insulin delivery (AID, or closed loop) based on sophisticated algorithms, are increasingly common. While these devices' efficacy in achieving near-normoglycemia is contributing to increasing usage among patients with diabetes, the management of these patients in operative and procedural environments remains understudied with limited published guidance available, particularly regarding AID systems. With their growing prevalence, practical management advice is needed for their utilization, or for the rational temporary substitution of alternative diabetes monitoring and treatments, during surgical care. CGM devices monitor interstitial glucose in real time; however, there are potential limitations to use and accuracy in the perioperative period, and, at the present time, their use should not replace regular point-of-care glucose monitoring. Avoiding perioperative removal of CGMs when possible is important, as removal of these prescribed devices can result in prolonged interruptions in CGM-informed treatments during and after procedures, particularly AID system use. Standalone insulin pumps provide continuous subcutaneous insulin delivery without automated adjustments for glucose concentrations and can be continued during some procedures. The safe intraoperative use of AID devices in their hybrid closed-loop mode (AID mode) requires the CGM component of the system to continue to communicate valid blood glucose data, and thus introduces the additional need to ensure this portion of the system is functioning appropriately to enable intraprocedural use. AID devices revert to non-AID insulin therapy modes when paired CGMs are disconnected or when the closed-loop mode is intentionally disabled. For patients using insulin pumps, we describe procedural factors that may compromise CGM, insulin pump, and AID use, necessitating a proactive transition to an alternative insulin regimen. Procedure duration and invasiveness is an important factor as longer procedures increase the risk of stress hyperglycemia, tissue malperfusion, and device malfunction. Whether insulin pumps should be continued through procedures, or substituted by alternative insulin delivery methods, is a complex decision that requires all parties to understand potential risks and contingency plans relating to patient and procedural factors. Currently available CGMs and insulin pumps are reviewed, and practical recommendations for safe glycemic management during the phases of perioperative care are provided.

Hyperglycemia, or glucose values >180 mg/dL, is associated with adverse post-operative outcomes. Our objective was to determine the impact of improving peri-operative glycemic control and evaluate infectious complications among patients with type 2 diabetes mellitus undergoing open gynecologic surgery.

A multidisciplinary team standardized pre-operative screening, referral algorithms, and intra-operative and post-operative hyperglycemia management (Surgical Universal euGlycemic Attainment during Recovery initiative). We compared outcomes between a baseline cohort (March 2016-December 2017) and an intervention cohort (February 2018-August 2022). Patients with type 1 diabetes, and planned minimally invasive, multi-team, or emergency surgery were excluded. Clinical and demographic characteristics were compared using the χ2 test, Fisher exact test, t test, or Wilcoxon rank-sum test, and generalized linear mixed models were used with a logit link function. All statistical analyses were performed using Stata/MP v17.0 (College Station, StataCorp).

We assessed 103 baseline patients and 167 intervention patients with diabetes. In the baseline cohort, 26 patients (25%) had hemoglobin A1C screened prior to surgery compared with 158 (95%) in the intervention cohort (p < .001). All surgical patients were screened for diabetes to determine eligibility, and we tracked the rate of patients newly diagnosed with type 2 diabetes (18 patients or 11%). The percentages of glucose values ≤180 mg/dL pre-operatively or intra-operatively were similar between cohorts, but the intervention cohort had increased compliance with assessing glucose intra-operatively (84% compared with 55%, p < .001). The percentage of post-operative glucose values ≤180 mg/dL increased from 77% in the baseline cohort to 86% in the intervention cohort (p = .002). The average post-operative glucose value was 10 mg/dL lower in the intervention cohort than in the baseline cohort (p = .005). Rates of surgical site infection, pneumonia, and urinary tract infection were similar between cohorts.

Our initiative improved compliance with pre-operative glycemic screening and decreased hyperglycemia among diabetic patients. We did not identify the correlation between glycemic control and infectious complications.

Literature review.

Review prehabilitation techniques used for elective spine surgery to create a comprehensive list of recommendations.

A systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines by searching three electronic databases from 1997 to 2021. Pertinent literature reporting information on prehabilitation, applicable to spine surgery, was identified. Seventy studies were selected for further analysis. Findings from the literature were reinforced by practices employed by the authors.

Preoperative smoking cessation should be achieved 3-4 weeks before elective spine surgery. Preoperative weight loss programs to reach a goal BMI <35 kg/m2 may be a viable solution to minimize wound complications and surgical site infections. To minimize the negative impact of cardiopulmonary comorbidities, patients can enroll in an exercise program prior to surgery. Patients should abstain from alcohol before elective spine surgery. Patients with osteoporosis may benefit from supplementation with Vitamin D, calcium, and parathyroid hormone. Opioids should be weaned to complete cessation 6-8 weeks before surgery. Preoperative cognitive behavioral therapy (CBT) and education seem to be the most beneficial in reducing complications associated with psychiatric comorbidities. Patients should engage in a comprehensive prehabilitation regimen.

Targeting patient risk factors with personalized interventions can improve postoperative outcomes in patients undergoing elective spine surgery.

The American Diabetes Association (ADA) "Standards of Care in Diabetes" includes the ADA's current clinical practice recommendations and is intended to provide the components of diabetes care, general treatment goals and guidelines, and tools to evaluate quality of care. Members of the ADA Professional Practice Committee, an interprofessional expert committee, are responsible for updating the Standards of Care annually, or more frequently as warranted. For a detailed description of ADA standards, statements, and reports, as well as the evidence-grading system for ADA's clinical practice recommendations and a full list of Professional Practice Committee members, please refer to Introduction and Methodology. Readers who wish to comment on the Standards of Care are invited to do so at professional.diabetes.org/SOC.

People with diabetes account for 25% of hospitalizations, or 8 million admissions annually. Poor glycemic control in the hospital is associated with increased morbidity, mortality, length of stay, and readmissions. Key considerations of inpatient diabetes management include initiation of appropriate insulin or medication regimens and frequent dose adjustments based on patient-specific factors. Inpatient diabetes management teams and new technologies are increasingly prevalent and can assist in achieving glycemic targets in the hospital. At discharge, standardized checklists should be used to ensure successful transitions of care.

The management of preoperative medications is an essential component of perioperative care for the cardiac surgical patient. This turnkey order set is part of a series created by the Enhanced Recovery After Surgery Cardiac Society, first presented at the Annual Meeting of The American Association for Thoracic Surgery in 2023. Numerous guidelines and expert consensus documents have been published to provide guidance in preoperative medication management. Our objective is to integrate these documents into an evidence-based order set that will facilitate standardized implementation of best practices for preoperative medication management for nonemergent adult cardiac surgery.

Subject matter experts were consulted to translate existing guidelines and peer reviewed literature into a sample turnkey order set for the preoperative management of patients' medications. Orders derived from consistent Class I, IIA, or equivalent recommendations across referenced guidelines and consensus manuscripts appear in the order set in bold type. Selected orders that were inconsistently Class I or IIA, Class IIB, or supported by published evidence, were also included in italicized type.

Holding antiplatelet and anticoagulant medications before nonemergent cardiac surgical procedures may reduce the risk of bleeding. Sodium-glucose co-transporter-2 inhibitors and glucagon-like peptide-1 agonists should also be discontinued to prevent acidosis and aspiration, respectively. Specific guidance for frequently used medications are complied within the manuscript, less frequently used medications are listed seperately.

Despite strong recommendations from major guidelines and consensus manuscripts, variation exists in preoperative medication orders, with limited availability of succinct implementation tools. This turnkey order set may facilitate standardized comprehensive preoperative medication management before nonemergent cardiac surgery.

The impact of routine preoperative anesthesia evaluations on potential perioperative complications remains unclear. This study aimed to investigate the effect of preoperative evaluation on early perioperative hemodynamic and respiratory complications.

This prospective observational study analyzed data from patients aged 18 to 80 who underwent elective surgery between October 15, 2023, and February 15, 2024. The study evaluated the effect of preoperative anesthesia evaluation on hemodynamic and respiratory complications occurring during surgery and within the first 24 h postoperatively, as well as its impact on the length of hospital stay.

The analysis included 1117 patients for whom complete data was available. Hemodynamic and respiratory complications were observed in 545 patients (48.7%), occurring within the first 24 h intraoperatively and postoperatively. Because no additional examinations beyond routine blood tests, radiological imaging, and electrocardiograms were performed in the preoperative period, the impact of these tests on the development of hemodynamic and respiratory complications could not be determined. There was no statistically significant association between the presence or absence of preoperative consultation and the occurrence of early perioperative hemodynamic and respiratory complications [OR (95% CI): 0.879 (0.646-1.195); P = 0.411], nor did it affect the length of hospital stay [median (IQR); 2 (3) vs. 2 (3); P = 0.245].

While the impact of routinely requested laboratory and imaging methods before surgery could not be assessed in this study, consultations that were requested did not affect hemodynamic and respiratory complications in the early perioperative period or on the duration of hospital stay.

Tight glycemic control is essential for optimal outcomes after coronary artery bypass graft (CABG) surgery, regardless of pre-operative diabetes status. The ideal timing for transitioning from intravenous (IV) to subcutaneous (SC) insulin remains unclear. This study addresses this knowledge gap by comparing the effects of early transition (postoperative day 1, POD1) versus delayed transition on glycemic control and patient outcomes after CABG surgery.

We analyzed data from a single tertiary medical center focusing on patients receiving insulin during their CABG hospitalization between 1 and 31 October 2022. We divided patients into two groups based on their transition timing: (1) Delayed Transition Group, patients transitioned from IV insulin infusion to SC insulin after POD1; and (2) Early Transition Group, patients transitioned on POD1. The primary outcome was the incidence of euglycemia on POD1. Secondary outcomes included rates of maintaining euglycemia from POD1 until POD10 or hospital discharge, hospital length of stay (LOS), ICU LOS, mean glucose levels, rates of hyperglycemia (blood glucose > 180 mg/dL) and hypoglycemia (blood glucose < 70 mg/dL), and rate of restarting IV insulin. Statistical analysis adjusted for BMI and diabetes diagnosis.

A total of 394 patients were enrolled, with 68 patients (17.3%) in the delayed-transition group and 326 patients (82.7%) in the early-transition group. Majority of the patients were males (74%), with an average age of 67 ± 9 years. Mean HbA1C and creatinine levels were comparable between the two groups. Patients in the early-transition group experienced a shorter ICU and hospital length of stay compared to the delayed-transition group, without a higher risk of restarting IV insulin.

Early transition from IV insulin drip to SC insulin on POD1 of CABG surgery reduces ICU and hospital LOS without increasing the risk of transitioning back to IV insulin.

Patients with hyperglycemia, thyroid dysfunction, and adrenal insufficiency face increased perioperative risk, which may be mitigated by appropriate management. This review addresses preoperative glycemic control, makes evidence-based recommendations for the increasingly complex perioperative management of noninsulin diabetes medications, and provides guideline-supported strategies for the perioperative management of insulin, including suggested indications for continuous intravenous insulin. The authors propose a strategy for determining when surgery should be delayed in patients with thyroid dysfunction and present a matrix for managing perioperative stress dose corticosteroids based on the limited evidence available.

Pulmonary aspiration in the perioperative period carries the risk of significant morbidity and mortality. As such, guidelines have been developed with the hopes of minimizing this risk by recommending fasting from solids and liquids over a specified amount of time. Point-of-care ultrasound has altered the landscape of perioperative medicine; specifically, gastric ultrasound plays a pivotal role in perioperative assessment. Further, the advent of glucagon-like-peptide-1 receptor agonists, the widespread use of cannabis, and Enhanced Recovery program carbohydrate beverage presents new challenges when attempting to standardize fasting guidelines. This review synthesizes the literature surrounding perioperative fasting guidelines specifically with regard to the use of point-of-care ultrasound in assessing for gastric contents and minimizing the risk of aspiration.

A host of anti-hyperglycemic agents are currently available and widely prescribed for diabetes and weight loss management. In patients undergoing surgery, use of these agents poses a clinical challenge to surgeons, anesthesiologists, and other perioperative care providers with regard to optimal timing of discontinuation and resumption of use, as well as possible effects of these agents on physiology and risk of postoperative complications. Here, we provide a comprehensive review of anti-hyperglycemic medications' effects on physiology, risks/benefits, and best practice management in the perioperative setting. Additionally, we report an illustrative case of small bowel obstruction in a patient taking semaglutide for 6 months prior to an otherwise uncomplicated laparoscopic hysterectomy and bilateral salpingo-oophorectomy. This review is meant to serve not as a replacement of, but rather as a consolidated complement to, various society guidelines regarding perioperative anti-hyperglycemic agent management.

Introduction: Perioperative dysglycemia is associated with negative surgical outcomes, including increased risk of infections and longer hospital stays. Continuous glucose monitoring (CGM) provides real-time glucose data, potentially improving glycemic control during surgery. However, the performance of CGM in the intraoperative environment has not been well established. This scoping review aimed to evaluate the performance of CGM systems during the intraoperative period, focusing on their technical reliability, accuracy, adverse device effects, and efficacy. Inclusion criteria: Studies that assessed intraoperative CGM performance, focusing on technical reliability, accuracy, adverse effects, or efficacy, were included. No restrictions were placed on the study design, surgical type, participant demographics, or publication date. Methods: A comprehensive literature search was performed using PubMed, EMBASE, and the Cochrane Library, covering publications up to 12 June 2024. Two independent reviewers screened and selected the studies for inclusion based on predefined eligibility criteria. Data extraction focused on the study characteristics, CGM performance, and outcomes. Results: Twenty-two studies were included, the majority of which were prospective cohort studies. CGM systems demonstrated a high technical reliability, with sensor survival rates above 80%. However, the accuracy varied, with some studies reporting mean or median absolute relative differences of over 15%. The adverse effects were minimal and mainly involved minor skin irritation. One randomized trial found no significant difference between CGM and point-of-care glucose monitoring for glycemic control. Conclusions: Although CGM has the potential to improve intraoperative glycemic management, its accuracy remains inconsistent. Future research should explore newer CGM technologies and assess their impact on surgical outcomes.

Insulin resistance (IR) is one of the independent determinants influencing the length of hospital stay (LOHS) and postoperative complications in colorectal procedures. Preoperative oral carbohydrate loading (OCL) has emerged as a prospective countermeasure for IR. This study aimed to investigate the effects of preoperative carbohydrate loading on postoperative IR, inflammatory parameters, and clinical outcomes in patients undergoing elective colorectal surgery.

This was an open-label, parallel arm, superiority randomized controlled trial conducted over 2 years. Participants were assigned to conventional fasting and oral OCL groups. IR, insulin sensitivity, Glasgow Prognostic Score (GPS), and interleukin 6 levels were analyzed on the day of surgery and on the first postoperative day (POD-1) and third POD (POD-3). Clinical parameters, such as thirst, hunger, dry mouth, anxiety, weakness, pain, nausea, and vomiting, were compared in the perioperative period. In addition, surgical clinical outcomes, such as intestinal recovery, time to independent ambulation, postoperative morbidity, and LOHS, were studied.

A total of 72 participants were included, with 36 in each group. In the OCL group, there was a statistically significant decrease in postoperative IR on the day of surgery, POD-1, and POD-3 (P = .0336). Similarly, inflammatory parameters and the GPS were found to be significantly lower in the OCL group (P < .001). Clinical parameters, such as thirst, hunger, and dry mouth, were significantly lower in the intervention group (P =.00), with a shortened LOHS.

This study demonstrated that preoperative carbohydrate loading is associated with reduced IR and inflammatory markers, shortened hospital stays, and improved overall clinical outcomes in elective colorectal surgery.

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have become one of the most popular medications for patients with diabetes and obesity. Due to their effects on gut motility via central or parasympathetic pathways, there have been concerns about an increased incidence of retained gastric contents and risk of aspiration in the perioperative period. Hence, the American Society of Anesthesiologists (ASA) recommends holding GLP-1 RAs on the procedure day or a week before the elective procedure based on the respective daily or weekly formulations, regardless of the dose, indication (obesity or diabetes), or procedure type. On the contrary, the American Gastroenterological Association (AGA) advises an individualized approach, stating that more data are needed to decide if and when the GLP-1 RAs should be held prior to elective endoscopy. Several retrospective and prospective studies, along with meta-analyses, have been published since then evaluating the role of GLP-1 RAs in patients scheduled for endoscopic procedures. In this review, we discuss the current clinical guidelines and available studies regarding the effect of GLP-1 RAs on GI endoscopies.

This consensus statement is a comprehensive update of the 2010 Society for Ambulatory Anesthesia (SAMBA) Consensus Statement on perioperative blood glucose management in patients with diabetes mellitus (DM) undergoing ambulatory surgery. Since the original consensus guidelines in 2010, several novel therapeutic interventions have been introduced to treat DM, including new hypoglycemic agents and increasing prevalence of insulin pumps and continuous glucose monitors. The updated recommendations were developed by an expert task force under the provision of SAMBA and are based on a comprehensive review of the literature from 1980 to 2022. The task force included SAMBA members with expertise on this topic and those contributing to the primary literature regarding the management of DM in the perioperative period. The recommendations encompass preoperative evaluation of patients with DM presenting for ambulatory surgery, management of preoperative oral hypoglycemic agents and home insulins, intraoperative testing and treatment modalities, and blood glucose management in the postanesthesia care unit and transition to home after surgery. High-quality evidence pertaining to perioperative blood glucose management in patients with DM undergoing ambulatory surgery remains sparse. Recommendations are therefore based on recent guidelines and available literature, including general glucose management in patients with DM, data from inpatient surgical populations, drug pharmacology, and emerging treatment data. Areas in need of further research are also identified. Importantly, the benefits and risks of interventions and clinical practice information were considered to ensure that the recommendations maintain patient safety and are clinically valid and useful in the ambulatory setting. What Other Guidelines Are Available on This Topic? Since the publication of the SAMBA Consensus Statement for perioperative blood glucose management in the ambulatory setting in 2010, several recent guidelines have been issued by the American Diabetes Association (ADA), the American Association of Clinical Endocrinologists (AACE), the Endocrine Society, the Centre for Perioperative Care (CPOC), and the Association of Anaesthetists of Great Britain and Ireland (AAGBI) on DM care in hospitalized patients; however, none are specific to ambulatory surgery. How Does This Guideline Differ From the Previous Guidelines? Previously posed clinical questions that were outdated were revised to reflect current clinical practice. Additional questions were developed relating to the perioperative management of patients with DM to include the newer therapeutic interventions.

Dexamethasone is associated with increased blood glucose levels that could impact patient outcomes or management. This study aimed to synthesize the available evidence regarding the impact of an intraoperative single dose of dexamethasone on blood glucose levels.

We searched CENTRAL, MEDLINE, and clinicaltrials.gov for randomized controlled trials (RCTs) comparing a single intraoperative dose of dexamethasone to control in adult patients who underwent noncardiac surgery. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the review was registered in PROSPERO (CRD42023420562). Data were pooled using a random-effects model. We reported pooled dichotomous data using odds ratios (OR) and continuous data using the mean difference (MD), reporting 95% confidence intervals (95% CIs), and corresponding P-values for both. Confidence in the evidence was appraised using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. As primary outcomes we assessed maximum blood glucose levels measurement and variation from baseline within 24 hours of surgery; blood glucose levels measurement and variation from baseline at 2, 4, 8, 12, and 24 hours after dexamethasone administration. As secondary outcomes, we evaluated insulin requirements and hyperglycemic events.

We included 23 RCTs, enrolling 11,154 participants overall. Dexamethasone was associated with a significant increment in blood glucose levels compared to control at all timepoints. The results showed an increase compared to control of 0.37 mmol L-1 (6.7 mg dL-1) at 2 hours (95% CI, 0.16-0.58 mmol L-1 or 2.9-10.5 mg dL-1), 0.97 mmol L-1 (17.5 mg dL-1) at 4 hours (95% CI, 0.67-1.25 mmol L-1 or 12.1-22.5 mg dL-1), 0.96 mmol L-1 (17.3 mg dL-1) at 8 hours (95% CI, 0.55-1.36 mmol L-1 or 9.9-24.5 mg dL-1), 0.90 mmol L-1 (16.2 mg dL-1) at 12 hours (95% CI, 0.62-1.19 mmol L-1 or 11.2-21.4 mg dL-1) and 0.59 mmol L-1 (10.6 mg dL-1) at 24 hours (95% CI, 0.22-0.96 mmol L-1 or 4.0-17.3 mg dL-1). No difference was found between subgroups regarding diabetic status (patients with diabetes versus patients without diabetes) in all the outcomes except 2 (maximum blood glucose levels variation within 24 hours and variation at 4 hours) and dexamethasone dose (4-5 mg vs 8-10 mg) in all the outcomes except 2 (blood glucose levels at 24 hours and hyperglycemic events).

Mean blood glucose levels rise between 0.37 and 1.63 mmol L-1 (6.7 and 29.4 mg dL-1) within 24 hours after a single dose of dexamethasone administered at induction of anesthesia compared to control, but in most patients this difference will not be clinically relevant.

People with diabetes receiving inpatient rehabilitation have multiple unique care needs. Although the condition, event, or disability resulting in admission to an inpatient rehabilitation facility (IRF) may not have a causal relationship with chronic conditions such as diabetes, the condition precipitating referral to IRF care may increase a person's risk for worsening cardiometabolic disease. Furthermore, diabetes management in the IRF setting may be complicated by stress hyperglycemia from illness and/or drug-induced hyperglycemia from the use of glucocorticoids or other offending medications. The availability of a multidisciplinary team of clinicians and therapists in the IRF setting holds great opportunity for development of robust diabetes care and education programs to optimize therapy, teach or reinforce diabetes self-management survival skills, and facilitate safe transitions of care to individuals' next setting of care.

Post-operative hyperglycemia is a known risk factor for post-surgical complications. The predictive value of pre-operative blood glucose levels, however, is less understood. This study aimed to determine if pre-operative screening blood glucose levels affect the rate of post-operative infection or wound complications. We also investigated if case urgency or anatomic location alters this relationship.

A single-institution retrospective chart review was performed to evaluate patients treated between 2018 and 2021. Subjects ≥ 18 years with closed, non-infected orthopaedic diagnoses requiring surgery were included. Case urgency, demographics, comorbidities, blood glucose level within twelve h prior to surgery, and hemoglobin A1c level within 3 months of surgery, were collected. Infections and wound complications were recorded as outcomes.

A total of 775 subjects with a mean age of 61 (range 18-96) were identified, including 543 elective and 232 trauma patients, with a mean pre-operative fasting glucose value of 127.7 mg/dL (range, 49-388 mg/dL) and average HbA1c of 6.9%. The odds of infectious complications were increased by a factor of 1.01 for every 1-point increase in blood glucose (95% CI 1.01-1.02; p < 0.01).

Pre-operative blood glucose levels greater than 137 mg/dL were associated with an increase in wound complications, but not deep infections. Infection rates stratified by anatomic site and case urgency were not impacted by pre-operative glucose levels. The increased risk of poor wound healing in patients with pre-operative hyperglycemia demonstrates that day of surgery point-of-care blood glucose screening can be a useful risk stratification tool.

The target glycemic control for nondiabetic patients in the postanesthesia care unit (PACU) after hysteroscopic surgery remains unclear. Our goal is to determine the optimal level of glycemic control by finding the relationship between blood glucose level (BGL) leaving the PACU and postoperative hypoglycemia in nondiabetic patients.

This retrospective cohort study was conducted at a comprehensive tertiary hospital in Chongqing, China between June 2018 and December 2020.

The target independent and dependent variables were BGL leaving the PACU and postoperative hypoglycemia, respectively. The primary outcome was the incidence of hypoglycemia. Logistic regression was used to explore the association between discharge BGL and hypoglycemia. The optimal glycemic control range was determined by using the receiver operating characteristic (ROC) curve.

Prior to insulin use, BGL in the insulin-using subgroup might be as high as 20 mmol/L. Hypoglycemia was related to the BGL while leaving the PACU (odds ratio (OR) 0.37 [95% confidence interval (CI) 0.22 to 0.65]). The best cut-off value (12.95 mmol/L) was determined by fitting the ROC curve.

If severe hyperglycemia develops during hysteroscopic surgery in individuals with 5% glucose as the mediator of uterine distention, the recommendation is to maintain blood glucose above 12.95 mmol/L when treated with insulin.

The prevalence of patients with coronary heart disease (CHD) and diabetes mellitus is notably high, posing significant residual cardiovascular risks even after routine interventions such as antihypertensive, lipid-lowering, and antithrombotic treatments. Recent studies have demonstrated that certain glucose-lowering medications confer cardiovascular benefits for patients with type 2 diabetes. However, a survey indicates that cardiologists may not be fully acquainted with the optimal screening timing, indicators, and diagnostic criteria for type 2 diabetes, and there is insufficient awareness and a low rate of prescription of novel glucose-lowering medications with proven cardiovascular efficacy, such as glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and sodium-glucose co-transporter-2 inhibitors (SGLT-2i). In this context, based on domestic and international guidelines or consensus and the latest evidence-based evidence, this consensus aims to standardize the glycemic management for patients with acute coronary syndrome, chronic coronary syndrome, and perioperative management for percutaneous coronary intervention. It highlights the key points of screening and diagnosis of type 2 diabetes, and the comprehensive management of cardiovascular risk in patients with CHD. The consensus elaborates on the principles and algorithms of glycemic management for CHD patients, without involving acute complications of diabetes, clarifies the clinical practice of glucose-lowering medications with cardiovascular benefits, and promotes the standardized use of these medications in cardiovascular and other related specialty fields. Additionally, it addresses the glucose-lowering treatment to comprehensively reduce cardiovascular risks.

A year ago, in a sample of 113 patients, our research group found that a high number of lymphocytes in the immediate postoperative period was correlated to a poor prognosis in cardiovascular surgeries. This study is an expansion of the initial study in order to confirm this finding.

We analyzed the data of 338 consecutive patients submitted to cardiovascular surgeries with cardiopulmonary bypass performed at Hospital Universitário Ciências Médicas (Belo Horizonte/Brazil) from 2015 to 2017. We analyzed 39 variables with the outcomes death, hospital stay, and intensive care unit stay.

The value of lymphocytes in the immediate postoperative period > 2175.0/mm³ was an indicator of poor prognosis in this sample (P<0.001). The variables female sex, age, high level of European System for Cardiac Operative Risk Evaluation II, increased stay in the intensive care unit and in the ward, elevation of creatinine in the preoperative period and at intensive care unit discharge, elevation of the percentage of immediate postoperative period segmented neutrophils, high immediate postoperative period neutrophil/lymphocyte ratio, fasting hyperglycemia, preoperative critical condition, reintubation, mild or transient acute renal failure, surgical infection, cardiopulmonary bypass, and aortic cross-clamping and mechanical ventilation durations also had an impact on the mortality outcome.

The value of lymphocytes in the immediate postoperative period > 2175.0/mm3 was an indicator of poor prognosis in cardiovascular surgery with cardiopulmonary bypass.

To study the effects of dexmedetomidine (DEX) on perioperative blood glucose levels in adult diabetes mellitus (DM) patients undergoing cardiac surgery.

A prospective, observational study was conducted on 100 adult diabetic patients aged between 18 and 75 years undergoing cardiac surgery with cardiopulmonary bypass (CPB). The patients were divided into two groups (group D and group C) of 50 each. Group D patients received DEX infusion, whereas the group C patients received 0.9% normal saline infusion.

The blood glucose levels, heart rate, mean arterial pressure, and serum potassium levels at different time points were comparable between the two groups (P > 0.05). The mean dose of insulin required in the combined population as well as in both controlled and uncontrolled DM patients was significantly less in group D than in group C (combined population - 36.03 ± 22.71 vs 47.82 ± 30.19 IU, P = 0.0297; uncontrolled DM - 37.36 ± 23.9 IU vs 48.16 ± 25.15 IU, P = 0.0301; controlled DM - 34.7 ± 21.5 IU vs 47.63 ± 35.25 IU, P = 0.0291). Duration of mechanical ventilation and VIS were comparable between the two groups. The incidence of arrhythmias (20% vs 46%, P = 0.0059) and delirium (6% vs 20%, P = 0.0384) was significantly less in group D than in group C. None of the patients in either group had stroke, myocardial ischemia, and mortality.

The results suggested that DEX infusion during the intraoperative period was very effective for perioperative glycemic control and reduction of insulin requirement in DM patients undergoing cardiac surgery.

Cardiac surgery with cardiopulmonary bypass results in global myocardial ischemia-reperfusion injury, leading to significant postoperative morbidity and mortality. Although cardioplegia is the cornerstone of intraoperative cardioprotection, a number of additional strategies have been identified. The concept of preconditioning and postconditioning, despite its limited direct clinical application, provided an essential contribution to the understanding of myocardial injury and organ protection. Therefore, physicians can use different tools to limit perioperative myocardial injury. These include the choice of anesthetic agents, remote ischemic preconditioning, tight glycemic control, optimization of respiratory parameters during the aortic unclamping phase to limit reperfusion injury, appropriate choice of monitoring to optimize hemodynamic parameters and limit perioperative use of catecholamines, and early reintroduction of cardioprotective agents in the postoperative period. Appropriate management before, during, and after cardiopulmonary bypass will help to decrease myocardial damage. This review aimed to highlight the current advancements in cardioprotection and their potential applications during cardiac surgery.

Glucagon-like peptide receptor agonists (GLP-1RA) are used to treat type 2 diabetes mellitus and, more recently, have garnered attention for their effectiveness in promoting weight loss. They have been associated with several gastrointestinal adverse effects, including nausea and vomiting. These side effects are presumed to be due to increased residual gastric contents. Given the potential risk of aspiration and based on limited data, the American Society of Anesthesiologists updated the guidelines concerning the preoperative management of patients on GLP-1RA in 2023. They included the duration of mandated cessation of GLP-1RA before sedation and usage of "full stomach" precautions if these medications were not appropriately held before the procedure. This has led to additional challenges, such as extended waiting time, higher costs, and increased risk for patients. In this editorial, we review the current societal guidelines, clinical practice, and future directions regarding the usage of GLP-1RA in patients undergoing an endoscopic procedure.

Approximately 15-50% of patients with Crohn's disease (CD) will require surgery within ten years following the diagnosis. The management of modifiable risk factors before surgery is essential to reduce postoperative complications and to promote a better postoperative recovery. Preoperative malnutrition reduced functional capacity, sarcopenia, immunosuppressive medications, anemia, and psychological distress are frequently present in CD patients. Multimodal prehabilitation consists of nutritional, functional, medical, and psychological interventions implemented before surgery, aiming at optimizing preoperative status and improve postoperative recovery. Currently, studies evaluating the effect of multimodal prehabilitation on postoperative outcomes specifically in CD are lacking. Some studies have investigated the effect of a single prehabilitation intervention, of which nutritional optimization is the most investigated. The aim of this narrative review is to present the physiologic rationale supporting multimodal surgical prehabilitation in CD patients waiting for surgery, and to describe its main components to facilitate their adoption in the preoperative standard of care.

Perioperative risk assessment and stratification before craniotomy is necessary to identify and optimize modifiable risk factors. Due to the high costs of diagnostic testing and concerns for delaying surgery, some have questioned whether and when surgery delays are warranted and supported by the current body of literature. The objective of this scoping review was to evaluate the available evidence on the prognostic value of preoperative risk assessment before anesthesia for elective craniotomy.

In this scoping review, we reviewed 156 papers that assess preoperative risk assessment before elective craniotomy, of which 27 papers were included in the final analysis.

There is little high-quality evidence to suggest significant risk reduction when 4 common preexisting abnormalities are present: preoperative chronic aspirin therapy, cardiac arrhythmias, deep vein thrombosis, or hyperglycemia.

The risk of delaying craniotomy should ultimately be weighed against the perceived risks associated the patient's comorbid conditions and should be considered on an individualized basis.

Severe perioperative hyperglycemia (SH) is a proven risk factor for postoperative complications after craniotomy. To reduce this risk, it has been proposed to implement the standardized clinical protocol for scheduled perioperative blood glucose concentration (BGC) monitoring. This would be followed by intravenous (IV) insulin infusion to keep BGC below 180 mg/dl in the perioperative period. The aim of this prospective observational study was to assess the impact of this type of protocol on the postoperative infection rate in patients undergoing elective craniotomy.

A total of 42 patients were prospectively enrolled in the study. Protocol included scheduled BGC monitoring in the perioperative period and rapid-acting insulin IV infusion when intraoperative SH was detected. The diagnosis of infection (wound, pulmonary, blood stream, urinary tract infection or central nervous system infection) was established according to CDC criteria within the first postoperative week. A previously enrolled group of patients with sporadic BGC monitoring and subcutaneous insulin injections for SH management was used as a control group.

An infectious complication (i.e., pneumonia) was diagnosed only in one patient (2 %) in the prospective group. In comparison with the control group, a decrease in the risk of postoperative infection was statistically significant with OR = 0.08 [0.009 - 0.72] (p = 0.02). Implementation of the perioperative BGC monitoring and the correction protocol prevented both severe hyperglycemia and hypoglycemia with BGC < 70 mg/dl.

Scheduled BGC monitoring and the use of low-dose insulin infusion protocol can decrease the postoperative infection rate in patients undergoing elective craniotomy. Future studies are needed to prove the causality of the implementation of such a protocol with an improved outcome.
