Impact of Serum Lactate as an Early Serum Biomarker for Cardiopulmonary Parameters within the First 24 Hours of Intensive Care Unit Treatment in Patients with Isolated Traumatic Brain Injury. Diagnostics (Basel) 2023; 13:diagnostics13101777. [PMID: 37238261 DOI: 10.3390/diagnostics13101777] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 05/03/2023] [Accepted: 05/16/2023] [Indexed: 05/28/2023] Open
Abstract
OBJECTIVE Cardiopulmonary (CP) complications are well-known phenomena in patients with isolated traumatic brain injury (iTBI) that can lead to tissue hypoperfusion and hypoxia. Serum lactate level is a well-known biomarker, indicating these systemic dysregulations in various diseases, but this has not been investigated in iTBI patients so far. The current study evaluates the association between serum lactate levels upon admission and CP parameters within the first 24 h of intensive care unit (ICU) treatment in iTBI patients. PATIENTS AND METHODS 182 patients with iTBI who were admitted to our neurosurgical ICU between December 2014 and December 2016 were retrospectively evaluated. Serum lactate levels on admission, demographic, medical, and radiological data upon admission, as well as several CP parameters within the first 24 h of ICU treatment, were analyzed, as well as the functional outcome at discharge. The total study population was dichotomized into patients with an elevated serum lactate level (lactate-positive) and patients with a low serum lactate level (lactate-negative) upon admission. RESULTS 69 patients (37.9%) had an elevated serum lactate level upon admission, which was significantly associated with a lower Glasgow Coma Scale score (p = 0.04), a higher head AIS score (p = 0.03), and a higher Acute Physiology and Chronic Health Evaluation II score (p = 0.01) upon admission, as well as a higher modified Rankin Scale score (p = 0.002) and a lower Glasgow Outcome Scale score (p < 0.0001) at discharge. Furthermore, the lactate-positive group required a significantly higher norepinephrine application rate (NAR; p = 0.04) and a higher fraction of inspired oxygen (FiO2; p = 0.04) to maintain the defined CP parameters within the first 24 h. CONCLUSION ICU-admitted iTBI patients with elevated serum lactate levels upon admission required higher CP support within the first 24 h of ICU treatment after iTBI. Serum lactate may be a helpful biomarker for improving ICU treatment in the early stages.

Abstract
Objective: Cardiopulmonary (CP) complications are well known in patients with an intracerebral hemorrhage (ICH) and could be associated with a higher serum lactate level. The present study aimed to assess the associations between the initial serum lactate level and the CP parameters within the first 24 h of intensive care unit (ICU) treatment in neurosurgical ICH patients. Patients and Methods: A total of 354 patients admitted to the ICU between 01/2009 and 12/2017 with a diagnosis of an ICH were retrospectively analyzed. Blood samples were taken upon admission, and each patient’s demographic, medical, and radiological data upon admission, as well as several CP parameters, were recorded within the first 24 h of ICU treatment. Results: A higher serum lactate level was associated with a lower GCS score (p < 0.0001), as well as a higher Acute Physiology and Chronic Health Evaluation II score (p = 0.002) upon admission. Additionally, patients with initially higher serum lactate levels had a significantly higher need for a norepinephrine application (p = 0.004) and inspiratory oxygen fraction (p = 0.03) within the first 24 h. Conclusion: Neurosurgical ICH patients with higher serum lactate levels upon admission require more CP support within the first 24 h of ICU treatment.

Abstract
Primary graft dysfunction (PGD) is a form of acute respiratory failure that complicates 30% of bilateral lung transplants. Higher grades of PGD correlate with higher severity of respiratory failure and unfavorable outcomes. Immediate PGD determination posttransplant‚ however, is not always predictive of PGD over subsequent days or intensive care unit outcomes. We aimed to evaluate whether extravascular lung water index (ELWI) measured immediately post bilateral lung transplant was associated with higher severity of PGD at 72 h and duration of mechanical ventilation.

Abstract
OBJECTIVE To evaluate the reliability of stroke volume variation (SVV) for predicting responsiveness to fluid therapy in patients undergoing cardiac and thoracic surgery. DESIGN Systematic review and meta-analysis. DATA SOURCES PubMed, EMBASE, Cochrane Library, Web of Science up to 9 August 2020. METHODS Quality of included studies were assessed with the Quality Assessment of Diagnostic Accuracy Studies-2 tool. We conducted subgroup analysis according to different anaesthesia and surgical methods with Stata V.14.0, Review Manager V.5.3 and R V.3.6.3. We used random-effects model to pool sensitivity, specificity and diagnostic odds ratio with 95% CI. The area under the curve (AUC) of receiver operating characteristic was calculated. RESULTS Among the 20 relevant studies, 7 were conducted during thoracic surgery, 8 were conducted during cardiac surgery and the remaining 5 were conducted in intensive critical unit (ICU) after cardiac surgery. Data from 854 patients accepting mechanical ventilation were included in our systematic review. The pooled sensitivity and specificity were 0.73 (95% CI: 0.59 to 0.83) and 0.62 (95% CI: 0.46 to 0.76) in the thoracic surgery group, 0.71 (95% CI: 0.65 to 0.77) and 0.76 (95% CI: 0.69 to 0.82) in the cardiac surgery group, 0.85 (95% CI: 0.60 to 0.96) and 0.85 (95% CI: 0.74 to 0.92) in cardiac ICU group. The AUC was 0.73 (95% CI: 0.69 to 0.77), 0.80 (95% CI: 0.77 to 0.83) and 0.88 (95% CI: 0.86 to 0.92), respectively. Results of subgroup of FloTrac/Vigileo system (AUC=0.80, Youden index=0.38) and large tidal volume (AUC=0.81, Youden index=0.48) in thoracic surgery, colloid (AUC=0.85, Youden index=0.55) and postoperation (AUC=0.85, Youden index=0.63) in cardiac surgery, passive leg raising (AUC=0.90, Youden index=0.72) in cardiac ICU were reliable. CONCLUSION SVV had good predictive performance in cardiac surgery or ICU after cardiac surgery and had moderate predictive performance in thoracic surgery. Nevertheless, technical and clinical variables may affect the predictive value potentially.

J Clin Monit Comput 2020; 35:779-785. [PMID: 32472337 DOI: 10.1007/s10877-020-00536-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Accepted: 05/25/2020] [Indexed: 11/28/2022]
Abstract
Among various methods for measuring the plasma volume (PV), the indocyanine green (ICG) dilution technique is a relatively less invasive method. However, the ICG method is rather cumbersome because 10 blood samples need to be obtained within a short time after ICG administration. Thus, reducing the frequency of blood sampling while maintaining the accuracy would facilitate plasma volume measurement in clinical situations. We here developed a modified method to measure plasma volume using 2260 ICG plasma concentration data from 115 surgical patients. The mean relative error (MRE) and the percentage of cases with relative error (RE) greater than 5% in total (PRE) were used to quantify the difference between plasma volumes obtained by the original and modified methods. RE was determined as follows. RE(%) = (PV obtained by original method (PVoriginal)-PV obtained by modified method (PVmodified))/PVoriginal × 100. PVmodified was assumed to be equal to PVoriginal when the RE was < 5%. When the number of samples selected for the plasma volume estimation was 4 or less, the PRE was mostly 10% or more. Five out of the 10 blood samples (order: 1st, 2nd, 3rd, 9th, and 10th) showed similar accuracies with the plasma volume obtained by the original method (original: 2.72 ± 0.64 l, modified: 2.72 ± 0.65 l). This modified method may be able to aptly replace the original method and lead to a wider clinical application of the ICG dilution technique. Further validation is needed to determine if the results of this study may be applied in other populations.

Pediatric living donor liver transplantation decade progress in Shanghai: Characteristics and risks factors of mortality. World J Gastroenterol 2020; 26:1352-1364. [PMID: 32256022 PMCID: PMC7109279 DOI: 10.3748/wjg.v26.i12.1352] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2019] [Revised: 02/17/2020] [Accepted: 02/28/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Pediatric living donor liver transplantation (LDLT) has become the gold standard for patients with end-stage liver disease. With improvements in organ preservation, immunosuppression, surgical and anesthesia techniques, the survival rates and long-term outcomes of patients after LDLT have significantly improved worldwide. However, data on anesthetic management and postoperative survival rate of pediatric LDLT in China are rare.
AIM To review the status of pediatric LDLT in Shanghai and investigate the factors related to anesthetic management and survival rate in pediatric LDLT.
METHODS We conducted a retrospective observational study to investigate the status of pediatric LDLT in Shanghai by reviewing 544 records of patients who underwent pediatric LDLT since the first operation on October 21, 2006 until August 10, 2016 at Renji Hospital and Huashan Hospital.
RESULTS The 30-d, 90-d, 1-year, and 2-year survival rates were 95.22%, 93.38%, 91.36%, and 89.34%, respectively. The 2-year patient survival rate after January 1, 2011 significantly improved compared with the previous period (74.47% vs 90.74%; hazard ratio: 2.92; 95% confidence interval (CI): 2.16–14.14; P = 0.0004). Median duration of mechanical ventilation in the intensive care unit (ICU) was 18 h [interquartile range (IQR), 15.25–20.25], median ICU length of stay was 6 d (IQR: 4.80–9.00), and median postoperative length of stay was 24 d (IQR: 18.00–34.00). Forty-seven (8.60%) of 544 patients did not receive red blood cell transfusion during the operation.
CONCLUSION Pediatric end-stage liver disease (PELD) score, anesthesia duration, operation duration, intraoperative blood loss, and ICU length of stay were independent predictive factors of in-hospital patient survival. Pediatric end-stage liver disease score, operation duration, and ICU length of stay were independent predictive factors of 1-year and 3-year patient survival.

Abstract
Background The assessment of hemodynamic variables is a mainstay in the management of critically ill patients. Hemodynamic variables may help physicians to choose among use of a vasopressor, an inotropic agent, or discontinuation of drugs. In this study, we aimed to investigate the usefulness of advanced hemodynamic variables in clinical decision-making. Methods Surveys regarding the case were administered to 25 surgeons working in nationally designated trauma centers or on trauma teams, using a voting system at a medical conference. The patient was a 67-year-old male with a crush injury of the left leg after a pedestrian traffic accident, who had aggravated pulmonary edema after leg amputation. Three clinical situations were given and the decision choices were: immediately after amputation, in 8 hours, and on the second day after amputation. Three kinds of variables from hemodynamic monitoring systems were provided for each clinical situation: conventional hemodynamic variables, including central venous pressure; variables from pulse contour analysis (PCA) [cardiac output (CO), stroke volume index, stroke volume variation (SVV), and systemic vascular resistance index); and variables from transpulmonary thermodilution (TPTD) technique (global ejection fraction and extravascular lung water index). The changes in decisions according to each provided hemodynamic variable were investigated and analyzed. Results The advanced hemodynamic parameters were considered to have a decisive effect on choosing vasopressors and inotropic agents. The decision was changed in 88% (22/25) of physicians using variables from the advanced monitoring systems. Among them, 82% (18/22) of physicians chose hemodynamic variables from the TPTD technique as their reason for change regarding management of a patient with severe pulmonary edema. Conclusions Advanced monitoring systems might be helpful in decision-making for critically ill patients. Multiple parameters and trends in change could be more important than a single value. Clinicians should select the system most appropriate according to its advantages and limitations, and interpret the variables obtained correctly.

Abstract
BACKGROUND Cardiogenic shock (CS) secondary to acute myocardial infarction (AMI) complicates management of the condition, and often leads to poor prognosis. Prompt and accurate monitoring of cardiovascular and accompanying hemodynamic changes is crucial in achieving adequate management of the condition. Advances in technology has availed procedures such as pulse index continuous cardiac output (PiCCO), which can offer precise monitoring of cardiovascular functions and hemodynamic parameters. In this study, PiCCO is evaluated for its potential utility in improving management and clinical outcomes among elderly patients with AMI complicated by CS.
AIM To assess whether use of the PiCCO system can improve clinical outcomes in elderly patients with AMI complicated by CS.
METHODS Patients from emergency intensive care units (EICU) or coronary care units (CCU) were randomized to receive PiCCO monitoring or not. The APACHE II score, SOFA score, hs-TnI, NT-proBNP, PaO2/FiO2 ratio and lactate levels on day 1, 3 and 7 after treatment were compared. The infusion and urine volume at 0-24 h, 24-48 h and 48-72 h were recorded, as were the cardiac index (CI), extravascular lung water index (EVLWI), intrathoracic blood volume index (ITBVI) and global end diastolic volume index (GEDVI) at similar time intervals.
RESULTS Sixty patients with AMI complicated by CS were included in the study. The PiCCO group had a significantly lower APACHE II score, SOFA score, hs-TnI and NT-proBNP levels on day 1, 3 and 7 after treatment. The infusion and urine volume during 0-24 h in the PiCCO group were significantly greater, and this group also showed significantly higher ADL scores. Furthermore, the PiCCO group spent lesser days on vasoactive agents, mechanical ventilation, and had a reduced length of stay in EICU/CCU. Additionally, the CI was significantly higher at 48 h and 72 h in the PiCCO group compared with that at 24 h, and the EVLWI, ITBVI and GEDVI were significantly decreased at 48 h and 72 h.
CONCLUSION Applying the PiCCO system could improve the clinical outcomes of elderly patients with AMI complicated by CS.

Abstract
BACKGROUND Pulse index continuous cardiac output (PiCCO) is used for hemodynamic assessment. This study describes real world extravascular lung water index (EVLWI) measurements at three time points and relates them to other hemodynamic parameters and mortality in critically ill patients admitted to a medical intensive care unit (ICU). METHODS A total of 198 patients admitted to a tertiary medical university hospital between February 2004 and December 2010 were included in this retrospective analysis. Patients were admitted for various diseases such as sepsis (n = 22), myocardial infarction (n = 53), pulmonary embolism (n = 3), cardiopulmonary resuscitation (n = 15), acute heart failure (AHF; n = 21) and pneumonia (n = 25). RESULTS Patients included in this analysis were severely ill as represented by the high simplified acute physiology score 2 (SAPS2, 42 ± 18) and acute physiology and chronic health evaluation score 2 (APACHE2' 22 ± 9). Real-world values at three time points are provided. Intra-ICU mortality rates did not differ between the EVLWI > 7 vs. the ELVWI < 7 groups (15% vs. 13%; p = 0.82) and no association between hemodynamic measurements obtained by PiCCO with long-term mortality could be shown. CONCLUSION There were no associations of any PiCCO measurements with mortality most probably due to selection bias towards severely ill patients. Future prospective studies with predefined inclusion criteria and treatment algorithms are necessary to evaluate the value of PiCCO for prediction of mortality against simple clinical tools such as jugular venous pressure, edema and auscultation.

Extravascular lung water index and Halperin score to predict outcome in critically ill patients. Wien Klin Wochenschr 2018; 130:505-510. [PMID: 30094662 DOI: 10.1007/s00508-018-1370-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2018] [Accepted: 07/15/2018] [Indexed: 12/11/2022]
Abstract
OBJECTIVE The aim of this study was to describe real world extravascular lung water index (EVLWI) measurements obtained by pulse index continuous cardiac output (PiCCO) on the day of admission. These were then related to a radiologic score for lung edema, Halperin score and both the Halperin score and EVLWI were assessed for prediction of in-hospital mortality in critically ill patients. METHODS AND RESULTS A total of 311 patients admitted to a tertiary medical university hospital between February 2004 and December 2010 were included in this retrospective analysis and of these 177 patients were intubated. In-hospital mortality was assessed by logistic regression. In the overall cohort, EVLWI and the Halperin score correlated poorly (r = 0.17; p = 0.02). In intubated patients, EVLWI and Halperin score did not correlate (r = 0.09; p = 0.39), whereas in patients who were not intubated there was a moderate association (r = 0.30; p = 0.007). In the overall cohort, (a) EVLWI (hazard ratio [HR] 1.10, 95% confidence interval [CI] 1.02-1.19; p = 0.01; area under the curve [AUC] 0.63, 95% CI 0.54-0.71) but not (b) Halperin score (HR 1.00, 95% CI 0.996-1.004; p = 0.94; AUC 0.52, 95% CI 0.45-0.58) was associated with in-hospital mortality There was a robust association of EVLWI (HR 1.12, 95% CI 1.01-1.25; p = 0.03) but not Halperin score (HR 1.003, 95% CI 0.997-1.009; p = 0.30) with mortality in non-intubated patients. In intubated patients, neither EVLWI (HR 0.997 95% CI 0.990-1.003; p = 0.33) nor Halperin score (HR 1.08; 95% CI 0.88-1.32; p = 0.47) was associated with mortality. CONCLUSION The EVLWI correlated moderately with a radiologic score for lung edema, the Halperin score, in non-intubated but not in intubated patients. The EVLWI at admission was associated with in-hospital mortality in our patient collective of critically ill patients and might constitute not only a tool for risk stratification but most importantly a valuable treatment goal.

Effects of Target Temperature Management on the Outcome of Septic Patients with Fever. BIOMED RESEARCH INTERNATIONAL 2017; 2017:3906032. [PMID: 29259979 PMCID: PMC5702415 DOI: 10.1155/2017/3906032] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/08/2017] [Accepted: 10/08/2017] [Indexed: 12/29/2022]
Abstract
Objectives To investigate the effects of target temperature management on hemodynamic changes, inflammatory and immune factors, and clinical outcomes of sepsis patients with fever. Methods Patients diagnosed with sepsis with a core temperature of ≥39°C were randomly divided into two groups: a low-temperature group (LT group: 36.5°C–38°C) and a high-temperature group (HT group: 38.5°C–39.5°C). A target core temperature was achieved within 6 hrs posttreatment and maintained for 24 hrs. Then, the hemodynamic changes, inflammatory and immune factors, and clinical outcomes were evaluated. Results Compared with the HT group, C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) showed a significant decrease in the LT group (P < 0.05). In contrast, IL-4 and IL-10 were higher in the LT group than in the HT group (P < 0.05). The CD4-T lymphocyte (CD4+), CD8-T lymphocyte (CD8+), and monocytic human leukocyte antigen-DR (mHLA-DR) in the LT group were higher than in the HT group (P < 0.05). The ICU stay and the anti-infection treatment costs were higher in the LT group (P < 0.05). Conclusion Low-temperature management of patients resulted in a low level of proinflammatory cytokines. Excessive temperature control in sepsis patients with fever may be harmful.

Abstract
PURPOSE This study aimed to investigate the clinical effects of early goal-directed therapy according to the global end-diastolic volume index (GEDI) on chronic obstructive pulmonary disease (COPD) patients with septic shock. METHODS A total of 71 COPD patients with septic shock were randomly assigned to 2 groups. In the control group (n = 37), fluid resuscitation was performed based on the central venous pressure. In the study group (n = 34), fluid resuscitation was performed until GEDI reached 800 mL/m2. The following indices were observed for the 2 groups: 6- and 24-hour fluid volumes, norepinephrine dosage, 24-hour blood lactate clearance rate, duration of mechanical ventilation, intensive care unit (ICU) length of stay, ICU mortality, and 90-day survival rate. RESULTS At both 6- and 24-hour measurements, the fluid volume was lower and norepinephrine dosage was higher in the control group than in the study group (P < .05). The blood lactate clearance rate was lower, the duration of mechanical ventilation was longer, and the length of stay in the ICU was longer in the control group than in the study group (P < .05). No significant difference in mortality or 90-day survival rate was found between the 2 groups. CONCLUSIONS The GEDI goal-directed fluid resuscitation shows better clinical effects than that shown by central venous pressure for COPD patients with septic shock; however, it cannot reduce the mortality rate.

Abstract
BACKGROUND Acupuncture has been used for treating heart failure mainly in combination with conventional treatments, but evidence for its effectiveness and safety has not been well established. Our aim was to review randomized controlled trials (RCTs) on acupuncture for heart failure and assess the clinical evidence. METHODS Electronic databases such as Medline, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL) and certain Chinese & Korean databases were searched until October 2015. The main outcomes assessed were mortality, New York Heart Association (NYHA) function classifications, and acupuncture-related adverse events. The details of acupuncture intervention were also investigated. RESULTS Among 4107 publications, seven RCTs were included; most of them showed considerable methodological flaws. We could not conduct a meta-analysis because of the heterogeneity of the included studies. In one acute heart failure study, acupuncture shortened intensive care unit (ICU) stay by 2.2days (95% CI 1.26, 3.14) and reduced the risk ratio of re-admission to 0.53 (95% CI 0.28, 0.99). However, mortality was not affected. Hemodynamic parameters also showed improvement. Another study reported an improved left ventricular ejection fraction by 9.95% (95% CI 3.24, 16.66). In five chronic heart failure studies, acupuncture improved exercise capacity, quality of life, hemodynamic parameters, and time domain heart rate variability parameters. Acupuncture decreased NT-pro BNP levels by 292.20 (95% CI -567.36, -17.04). No adverse effects were reported. CONCLUSIONS The effectiveness of acupuncture as a therapy for heart failure is currently inconclusive. Further large and rigorous clinical trials are needed to establish its clinical utility.

Abstract
Recently, the measurement of indicator dilution curves using a photoacoustic (PA) technology was reported, which showed promising results on the noninvasive estimation of cardiac output (CO) that is an important hemodynamic parameter useful in various clinical situations. However, in clinical practice, measuring PA indicator dilution curves from an arterial blood vessel requires an ultrasound transducer array capable of focusing on the targeted artery. This causes several challenges on the clinical translation of the PA indicator dilution method, such as high sensor cost and complexity. In this paper, we theoretically derived that a composite PA indicator dilution curve simultaneously measured from both arterial and venous blood vessels can be used to estimate CO correctly. The ex-vivo and in-vivo experimental results with a flat ultrasound transducer verified the developed theory. We believe this new concept would overcome the main challenges on the clinical translation of the noninvasive PA indicator dilution technology.

Abstract
AIM To explore the variations between acute care and intensive care nurses' understanding of patient deterioration according to their use of this term in published literature. BACKGROUND Evidence suggests that nurses on wards do not always recognize and act upon patient deterioration appropriately. Even if resources exist to call for intensive care nurses' help, acute care nurses use them infrequently and the problem of unattended patient deterioration remains. DESIGN Dimensional analysis was used as a framework to analyze papers retrieved in a nursing-focused database. METHOD A thematic analysis of 34 papers (2002-2012) depicting acute care and intensive care unit nurses' perspectives on patient deterioration was conducted. FINDINGS No explicit definition of patient deterioration was retrieved in the papers. There are variations between acute care and intensive care unit nurses' accounts of this concept, particularly regarding the validity of patient deterioration indicators. Contextual factors, processes and consequences are also explored. CONCLUSIONS From the perspectives of acute care and intensive care nurses, patient deterioration can be defined as an evolving, predictable and symptomatic process of worsening physiology towards critical illness. Contextual factors relating to acute care units (ACU) appear as barriers to optimal care of the deteriorating patient. This work can be considered as a first effort in modelling the concept of patient deterioration, which could be specific to ACU. RELEVANCE TO CLINICAL PRACTICE The findings suggest that it might be relevant to include subjective indicators of patient deterioration in track and trigger systems and educational efforts. Contextual factors impacting care for the deteriorating patient could be addressed in further attempts to deal with this issue.

Abstract
BACKGROUND Cardiac complications are an important cause of morbidity and mortality observed after esophageal resections. We examined whether an high intrathoracic vagotomy during abdominothoracic esophagectomy would have an effect on intraoperative and early postoperative cardiac function in the setting of a minimally invasive resection. Two hypotheses were generated for this study: (1) Vagotomy would cause cardiac changes, and (2) vagus-preserving esophagectomy would prevent cardiac problems during resection and in the early postoperative phase. METHODS AND RESULTS Thirty male pigs were operated on while cardiac parameters (heart rate [HR], cardiac index [CI], preload recruitable stroke work [PRSW], contractility speed [dp/dtmax], relaxation speed [dp/dtmin], and relaxation time [tau]) were monitored using a conductance catheter and the thermodilution method. Animals were randomized into 4 groups (each n = 7): (1) control, thoracoscopy only, (2) thoracoscopy with vagotomy, (3) esophageal resection with vagotomy, and (4) esophageal resection with vagus nerve preservation. To evaluate the first hypothesis, we compared groups 1 and 2; to evaluate the second hypothesis, we compared groups 3 and 4. HR, CI, PRSW, dp/dtmax, and tau were different in the 2 groups without resection (area under the curve; each P < .05). Vagotomy with esophagectomy resulted in nonsignificant differences between groups 3 and 4. The requirement for metoprolol administration to avoid severe tachycardia was greater in the groups that underwent vagotomy (P < .05; Fisher's exact test). CONCLUSION An high intrathoracic vagotomy results in loss of vagal tone and a greater rate of tachycardia during thoracoscopy and esophagectomy. There were no differences, however, in cardiac dynamics between the esophagectomy groups. Thus, vagal injury is not the sole reason for cardiac dysfunction after esophagectomy.

Abstract
AIM: To investigate extravascular lung water indexed to predicted body weight (EVLWIp) and actual body weight (EVLWIa) on outcome of patients with severe sepsis.
METHODS: Transpulmonary thermodilution was prospectively used to measure cardiovascular hemodynamics, EVLWIp and EVLWIa via an arterial catheter placed in each patient within 48 h of meeting the criteria for severe sepsis from a medical intensive care unit (ICU) at a university affiliated hospital. Survival was the single dependent variable. In order to examine and compare the predictive power of EVLWIp, EVLWIa and other clinically significant factors in predicting the in-hospital survival status of severe sepsis patients in the medical ICU, a receiver operating characteristic (ROC) curve method to analyze the significant variables and the area under the ROC curve (AUC) of the variables, P value and 95%CI were calculated.
RESULTS: In total, 33 patients were studied. In the ROC curve method analyses, EVLWIp (the AUC: 0.849; P = 0.001, 95%CI: 0.72-0.98) was as predictive for in-hospital survival rate as variables with EVLWIa (AUC, 0.829; P = 0.001, 95%CI: 0.68-0.98). The proportion of patients surviving with a low EVLW (EVLWI < 10 mL/kg) was better than that of patients with a higher EVLW, whether indexed by actual (HR = 0.2; P = 0.0002, 95%CI: 0.06-0.42) or predicted body weight (HR = 0.13; P < 0.0001, 95%CI: 0.05-0.35) during their hospital stay with the Kaplan-Meier method (76% vs 12.5%, respectively).
CONCLUSION: This investigation proposed that EVLWIp is as good a predictor as EVLWIa to predict in-hospital survival rate among severe sepsis patients in the medical ICU.

Abstract
Hemodynamic monitoring and management has greatly improved during the past decade. Technologies have evolved from very invasive to non-invasive, and the philosophy has shifted from a static approach to a functional approach. However, despite these major changes, the critical care community still has potential to improve its ability to adopt the most modern standards of research methodology in order to more effectively evaluate new monitoring systems and their impact on patient outcome. Today, despite the huge enthusiasm raised by new hemodynamic monitoring systems, there is still a big gap between clinical research studies evaluating these monitors and clinical practice. A few studies, especially in the perioperative period, have shown that hemodynamic monitoring systems coupled with treatment protocols can improve patient outcome. These trials are small and, overall, the corpus of science related to this topic does not yet fit the standard of clinical research methodology encountered in other specialties such as cardiology and oncology. Larger randomized trials or quality improvement processes will probably answer questions related to the real impact of these systems.

Abstract
Because of the increasing age of the population, critical care and emergency medicine physicians have seen an increased number of critically ill patients over the last decade. Moreover, the trend of hospital closures in the United States t imposes a burden of increased efficiency. Hence, the identification of devices that facilitate accurate but rapid assessments of hemodynamic parameters without the added burden of invasiveness becomes tantamount. The purpose of this review is to understand the applications and limitations of these new technologies.

Abstract
BACKGROUND Less invasive methods of determining cardiac output are now readily available. Using indicator dilution technique, for example has made it easier to continuously measure cardiac output because it uses the existing intra-arterial line. Therefore gone is the need for a pulmonary artery floatation catheter and with it the ability to measure left atrial and left ventricular work indices as well the ability to monitor and measure a mixed venous saturation (SvO(2)). PURPOSE The aim of this paper is to put forward the notion that SvO(2) provides valuable information about oxygen consumption and venous reserve; important measures in the critically ill to ensure oxygen supply meets cellular demand. In an attempt to portray this, a simplified example of the septic patient is offered to highlight the changing pathophysiological sequelae of the inflammatory process and its importance for monitoring SvO(2). RELEVANCE TO CLINICAL PRACTICE SvO(2) monitoring, it could be argued, provides the gold standard for assessing arterial and venous oxygen indices in the critically ill. For the bedside ICU nurse the plethora of information inherent in SvO(2) monitoring could provide them with important data that will assist in averting potential problems with oxygen delivery and consumption. However, it has been suggested that central venous saturation (ScvO(2)) might be an attractive alternative to SvO(2) because of its less invasiveness and ease of obtaining a sample for analysis. There are problems with this approach and these are to do with where the catheter tip is sited and the nature of the venous admixture at this site. Studies have shown that ScvO(2) is less accurate than SvO(2) and should not be used as a sole guiding variable for decision-making. These studies have demonstrated that there is an unacceptably wide range in variance between ScvO(2) and SvO(2) and this is dependent on the presenting disease, in some cases SvO(2) will be significantly lower than ScvO(2). CONCLUSION Whilst newer technologies have been developed to continuously measure cardiac output, SvO(2) monitoring is still an important adjunct to clinical decision-making in the ICU. Given the information that it provides, seeking alternatives such as ScvO(2) or blood samples obtained from femorally placed central venous lines, can unnecessarily lead to inappropriate treatment being given or withheld. Instead when using ScvO(2), trending of this variable should provide clinical determinates that are useable for the bedside ICU nurse, remembering that in most conditions SvO(2) will be approximately 16% lower.

Abstract
The aim of this article was to provide a resource for critical care nurses wishing to further their understanding of inotropic drugs used in critical care. The physiology of cardiac output and blood pressure is examined along with an explanation of adrenergic receptors acted on by inotropes. Some common indications for inotropic therapy are discussed, along with essential patient monitoring and dose calculations to ensure safe therapeutic ranges are observed. Some of the most commonly used positive inotropes used in critical care environments are individually explored, providing indications and some of the latest research relating to their uses. Frequently, observed side effects of individual inotropes are also offered, enabling the nurse to maintain patient safety when administering these potent drugs. Some major nursing and professional issues related to inotrope therapy and medicine administration are discussed, as well as some recommended practices in renewing infusions.

Abstract
BACKGROUND Animal experiments showed that recruitment maneuver (RM) and protective ventilation strategy of the lung could improve oxygenation and reduce extravascular lung water. This study was to investigate the effects of RM on respiratory mechanics and extravascular lung water index (EVLWI) in patients with acute respiratory distress syndrome (ARDS). METHODS Thirty patients with ARDS were randomized into a RM group and a non-RM group. In the RM group, after basic mechanical ventilation stabilized for 30 minutes, RM was performed and repeated once every 12 hours for 3 days. In the non-RM group, lung protective strategy was conducted without RM. Oxygenation index (PaO2/FiO2), peak inspiratory pressure (PIP), Plateau pressure (Pplat), static pulmonary compliance (Cst) and EVLWI of patients before treatment and at 12, 24, 48, 72 hours after the treatment were measured and compared between the groups. Hemodynamic changes were observed before and after RM. One-way ANOVA, Student's t test and Fisher's exact test were used to process the data. RESULTS The levels of PaO2/FiO2 and Cst increased after treatment in the two groups, but they were higher in the RM group than in the non-RM group (P<0.05). The PIP and Pplat decreased after treatment in the two groups, but they were lower in the RM group than in the non-RM group (P<0.05). The EVLWI in the two groups showed downward trend after treatment (P<0.05), and the differences were signifcant at all time points (P<0.01); the EVLWI in the RM group was lower than that in the non-RM group at 12, 24, 48 and 72 hours (P<0.05 or P<0.01). Compared with pre-RM, hemodynamics changes during RM were significantly different (P<0.01); compared with pre-RM, the changes were not significantly different at 120 seconds after the end of RM (P>0.05). CONCLUSIONS RM could reduce EVLWI, increase oxygenation and lung compliance. The effect of RM on hemodynamics was transient.

Abstract
UNLABELLED Anesthesia for abdominal multivisceral transplantation (MVTx) is challenging. Surgical success depends on hemodynamic stability throughout organ removal from the donor and engraftment in recipients. The aim of the current study was to summarize our experience with anesthetic management including monitoring of hemodynamic changes in pigs during MVTx procedures. MATERIALS AND METHODS Ten male pigs were randomly divided into two groups: donors and recipients for five MVTxs. A pulmonary artery catheter (PAC), transesophageal echocardiography (TEE), and pulse indicator continuous cardiac output (PiCCO) were used intraoperatively in recipients to monitor hemodynamic changes. RESULTS Two recipients had cardiac arrest and died intraoperatively presumably due to hypovolemia. The data obtained by PAC and TEE from three successful cases showed huge changes in hemodynamics during the stages of organ removal and reperfusion after engraftment. Use of PiCOO in one of those three cases allowed successful fluid management, resulting in stable intraoperative hemodynamics. CONCLUSION The anesthetic management for MVTx surgery was improved by PAC, TEE, and PiCOO monitoring.

Abstract
BACKGROUND Hypovolemia is a common clinical entity in critical patients, and adequate volume replacement therapy seems to be essential for maintaining tissue perfusion. However, it is still uncertain which solution is most appropriate for fluid resuscitation. OBJECTIVE The aim of this study was to investigate the effects of fluid resuscitation with 3.5% polygeline versus 6% hydroxyethyl starch solutions on hemodynamic functions and liver functions assessed with a noninvasive liver function monitoring system (LIMON) in hypovolemic patients. DESIGN This study is a prospective randomized clinical trial. MEASUREMENTS AND RESULTS Thirty hypovolemic patients (intrathoracic blood volume index, <850 mL/m(2)) were randomized into hydroxyethyl starch (mean molecular weight, 130,000 Da) and polygeline (mean molecular weight, 30,000 Da) groups (15 patients each). Indocyanine green plasma disappearance elimination (ICG-PDR) were conducted concurrently using LIMON. A dose of 0.3 mg/kg ICG was given through a cubital fossa vein as a bolus. For fluid resuscitation, 500 mL of colloid was given to the patients. Repeated hemodynamic and ICG-PDR measurements were done at baseline, after infusion, and then at 30 minutes after infusion. RESULTS Intrathoracic blood volume index and systolic, diastolic, and mean blood pressures increased significantly after infusion and remained elevated for 30 minutes after infusion, but there was no significant difference between the 2 groups. Indocyanine green plasma disappearance elimination values were similar in both groups with no significant difference between the two. CONCLUSION Increasing intrathoracic blood volume index and hemodynamic variables by fluid loading is not associated with a significant change in ICG-PDR.

Abstract
BACKGROUND This study was designated to investigate whether extravascular lung water index (EVLI) is an independent predictor for mortality outcome in patients with severe sepsis. METHODS This study prospectively recruited patients with severe sepsis from a medical intensive care unit (ICU) at a university affiliated hospital. In each patient, transpulmonary thermodilution was used to measure cardiovascular hemodynamics and EVLI via an arterial catheter placed within 48h of the patient meeting the criteria for severe sepsis. RESULTS In total, 33 patients were studied. EVLI, Acute Physiology and Chronic Health Evaluation (APACHE) II score, development of acute respiratory distress syndrome, chest X-ray score, lung injury score, body mass index, prior 24h fluid balance, albumin, and white blood cell counts were shown to be predictors of in-hospital survival by a bivariate analysis. In multinominal logistic regression, EVLI (adjusted odds ratio, 6.21; p=0.01; 95% confidence interval, 1.05-1.44) acted as an independent predictor for in-hospital survival. A cut-off value for EVLI of 10ml/kg had good sensitivity (88.2%) and specificity (68.7%) by ROC curve analysis. Medical ICU patients with extremely severe sepsis and a high EVLI (> or =10ml/kg) had lower in-hospital survival rate than those with a low EVLI (<10ml/kg) (15% vs. 67.7%, respectively, p<0.001. CONCLUSIONS This investigation suggested that EVLI was an independent predictor for in-hospital survival in medical ICU patients with severe sepsis. Measurement of EVLI may be used for risk stratification among those patients.

Abstract
Derangements in the circulation are a common feature of sepsis, trauma, major surgery and other critical illnesses. Detailed evaluation of the circulation is therefore an essential aspect of the clinical management of such patients. The use of cardiac output monitoring technology is an increasingly important aspect of evaluating patients in the operating theatre, critical care unit and elsewhere. There are now a number of different technologies available for this purpose, which use a diverse range of physiological principles. A detailed understanding of the physiological principles applied by such technology is essential for safe and effective use in clinical practice. The aim of this article is to describe the physiological principles used to measure cardiac output and their application in various monitors in common clinical use.

Abstract
OBJECTIVE To assess the ability to track changes in cardiac index (Delta CI) induced by volume loading using continuous pulsed heat thermodilution (CCO), and pulse contour (PCCO) cardiac output (CO) with transpulmonary thermodilution (TD(tp)) CO as reference. DESIGN Prospective observational clinical trial. SETTING Intensive care unit. PATIENTS Twelve ventilated and sedated post-operative cardiac surgery patients. MEASUREMENTS AND RESULTS Each patient had a 7.5F CCO pulmonary artery catheter (Edwards Lifesciences) and a 5F, 20 cm PCCO femoral artery catheter (Pulsion Medical Systems). Forty-five data sets were taken before and after 25 volume loadings of 5 mL/kg of 4% albumin. Volume loading resulted in an increase in CI (2.84 L/(min m(2)) versus 3.12L/(min m(2)), p<.05) although only nine volume loadings changed CI (Delta CI)> or =14%. The change in CI using PCCO (Delta PCCI) was correlated with Delta CI (TD(tp)) (R(2)=.50, p<.0001), whilst Delta CI using CCO (Delta CCI) was not (R(2)=.14). The bias and limits of agreement (LOA) between Delta TD(tp)CI and Delta PCCI was 6.2% (95% CI, +/-5.8%) and 28.4% (95% CI, +/-38.2%) respectively. Delta TD(tp)CI and Delta CCI has a bias of 2.6% (95% CI, +/-8.3%) and LOA of 39.6% (95% CI, +/-63%). Both Delta PCCI and Delta CCI reliably tracked Delta CI> or =14%. CONCLUSION In this small group of patients the continuous cardiac output methods tracked changes in CI, although, in individual cases they did not change in the same direction as the thermodilution method. Critical care nurses need to critically appraise the accuracy and clinical relevance of continuous CO data within the clinical context.

Abstract
Cardiac output (CO) determination by pulmonary artery (PA) catheter has increasingly been criticised within the literature due to its invasive nature and poor correlation between the pressure measurements and intravascular volume status in mechanically ventilated patients. Consequently, alternative less invasive technologies to PA catheterisation are emerging within intensive care. One such novel technology are pulse contour CO (PCCO) systems. They establish comprehensive and continuous haemodynamic monitoring utilising a central venous catheter (CVC) and an arterial line. Furthermore, a key feature of this technology is its ability to produce intrathoracic volume measurements which may provide a better estimation of cardiac preload as well as indicate the presence and severity of pulmonary oedema. This article aims to discuss the theoretical basis and clinical application of PCCO systems, how PCCO systems differ from PA catheters and how the intrathoracic volume measurements are derived. Understanding these advanced concepts will ensure that clinicians are able to employ this innovative monitoring technology more effectively.

Abstract
Over the past decade the practice of acute resuscitation and its monitoring have undergone significant changes. Utilization of noninvasive mechanical ventilation, goal-directed therapy, restricted fluid volume, blood transfusion and minimally invasive technology for monitoring tissue oxygenation have changed the practice of acute resuscitation. Early diagnosis and definitive treatment of the underlying cause of shock remains the mainstay for survival after successful resuscitation. Patient-centered outcome end-points, in addition to survival, are being utilized to appraise the effectiveness of treatment. Application of medical ethics to the ever changing practice of acute resuscitation has also become a societal expectation.
