Effects of immediate extubation in the operating room on long-term outcomes in living donor liver transplantation: a retrospective cohort study. Anesth Pain Med (Seoul) 2025; 20:50-60. [PMID: 39923771 PMCID: PMC11834885 DOI: 10.17085/apm.24042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 10/14/2024] [Accepted: 11/11/2024] [Indexed: 02/11/2025] Open
Abstract
BACKGROUND Living-donor liver transplantation (LDLT) is a viable alternative to deceased-donor liver transplantation. Enhanced recovery after surgery protocols that include early extubation offer short-term benefits; however, the effect of immediate extubation in the operating room (OR) on long-term outcomes in patients undergoing LDLT remains unknown. We hypothesized that immediate OR extubation is associated with improved long-term outcomes in patients undergoing LDLT. METHODS This retrospective cohort study included 205 patients who underwent LDLT. The patients were classified based on the extubation location as OREX (those extubated in the OR) or NOREX (those extubated in the intensive care unit [ICU]). The primary outcome was overall survival (OS), while secondary outcomes included ICU stay, hospital stay duration, and various postoperative outcomes. RESULTS Among the 205 patients, 98 (47.8%) underwent extubation in the OR after LDLT. Univariate analysis revealed that OR extubation did not significantly affect OS (hazard ratio [HR]: 0.50, 95% confidence interval [CI]: 0.24-1.05; P = 0.066). Furthermore, multivariate analysis revealed no statistically significant association between OR extubation and OS (HR: 0.79, 95% CI: 0.35-1.80; P = 0.580). However, OR extubation was significantly associated with a lower incidence of 30-day composite complications and shorter ICU and hospital stays. Multivariate analysis indicated that higher preoperative platelet counts, increased serum creatinine levels, and a longer surgery duration were associated with poorer OS. CONCLUSIONS Immediate OR extubation following LDLT surgery was associated with fewer 30-day composite complications and shorter ICU and hospital stays; however, it did not significantly improve OS compared with ICU extubation.

Abstract
OBJECTIVES Prolonged tracheal intubation and mechanical ventilation after liver transplant increase postoperative complications. Hence, timely extubation should be considered; however, a standard clinical criteria set or scoring system to select patients has not been established for early extubation after livertransplant.We investigated the factors that affect early extubation to design a predictive scoring system for early extubation. MATERIALS AND METHODS This study is a case-control study of adult liver transplant patients. Preoperative, intraoperative, and postoperative clinical data were collected. Early extubation was defined as tracheal extubation immediately or up to 6 hours posttransplant. The variables were compared between the early extubation group and the delayed extubation (>6 hours) group. RESULTS Our study enrolled 237 patients; among them, 57 patients (24%) were in the early extubation group, and 180 (76%) were in the delayed extubation group. Multiple logistic regression analysis showed that postoperative base excess level at admission to the intensive care unit, number of units of packed red blood cells transfused during surgery, urine volume, and excess base level 6 hours after surgery were the main predictors of successful early extubation. CONCLUSIONS The initial base excess level at the entrance to the intensive care unit(postsurgery) and 6 hours after surgery, packed red blood cell volume transfused during surgery, and urine volume 6 hours after surgery are the main predictors for a successful early tracheal extubation.These factors are considered for the Shiraz Extubation Predictor formula.

Abstract
Prior to the 1990s, prolonged postoperative intubation and admission to the intensive care unit was considered the standard of care following liver transplantation. Advocates of this practice speculated that this time allowed patients to recover from the stress of major surgery and allowed their clinicians to optimize the recipients' hemodynamics. As evidence in the cardiac surgical literature on the feasibility of early extubation grew, clinicians began applying these principles to liver transplant recipients. Further, some centers also began challenging the dogma that patients need to be cared for in the intensive care unit following liver transplantation and instead transferred patients to the floor or stepdown units immediately following surgery, a technique known as "fast-track" liver transplantation. This article aims to provide a history of early extubation for liver transplant recipients and offer practical advice on how to select patients that may be able to bypass the intensive care unit and be recovered in a non-traditional manner.

Abstract
BACKGROUND Immediate postoperative extubation (IPE) can reduce perioperative complications and length of stay (LOS), however it is performed variably after liver transplant across institutions and has historically excluded high-risk recipients from consideration. In late 2012, we planned and implemented a single academic institution structured quality improvement (QI) initiative to standardize perioperative care of liver transplant recipients without exceptions. We hypothesized that such an approach would lead to a sustained increase in IPE after primary (PAC) and delayed abdominal closure (DAC). METHODS We retrospectively studied 591 patients from 2013 to 2018 who underwent liver transplant after initiative implementation. We evaluated trends in incidence of IPE versus delayed extubation (DE), and reintubation, LOS, and mortality. RESULTS Overall, 476/591 (80.5%) recipients underwent PAC (278 IPE, 198 DE) and 115/591 (19.5%) experienced DAC (39 IPE, 76 DE). When comparing data from 2013 to data from 2018, the incidence of IPE increased from 9/67 (13.4%) to 78/90 (86.7%) after PAC and from 1/12 (8.3%) to 16/23 (69.6%) after DAC. For the same years, the incidence of IPE after PAC for recipients with MELD scores ≥30 increased from 0/19 (0%) to 12/17 (70.6%), for recipients who underwent simultaneous liver-kidney transplant increased from 1/8 (12.5%) to 4/5 (80.0%), and for recipients who received massive transfusion (>10 units of packed red blood cells) increased from 0/17 (0%) to 10/13 (76.9%). Reintubation for respiratory considerations <48 h after IPE occurred in 3/278 (1.1%) after PAC and 1/39 (2.6%) after DAC. IPE was associated with decreased intensive care unit (HR of discharge: 1.92; 95% CI: 1.58, 2.33; P < 0.001) and hospital LOS (HR of discharge: 1.45; 95% CI: 1.20, 1.76; P < 0.001) but demonstrated no association with mortality. CONCLUSION A structured QI initiative led to sustained high rates of IPE and reduced LOS in all liver transplant recipients, including those classified as high risk.

Abstract
In this review, we describe the major milestones in the development of organ transplantation with a specific focus on hepatic transplantation. For many years, the barriers preventing successful organ transplantation in humans seemed insurmountable. Although advances in surgical technique provided the technical ability to perform organ transplantation, limited understanding of immunology prevented successful organ transplantation. The breakthrough to success was the result of several significant discoveries between 1950 and 1980 involving improved surgical techniques, the development of effective preservative solutions, and the suppression of cellular immunity to prevent graft rejection. After that, technical innovations and laboratory and clinical research developed rapidly. However, these advances alone could not have led to improved transplant outcomes without parallel advances in anesthesia and critical care. With increasing organ demand, it proved necessary to expand the donor pool, which has been achieved with the use of living donors, split grafts, extended criteria organs, and organs obtained through donation after cardiac death. Given this increased access to organs and organ resources, the number of transplantations performed every year has increased dramatically. New regulatory organizations and transplant societies provide critical oversight to ensure equitable organ distribution and a high standard of care and also perform outcome analyses. Establishing dedicated transplant anesthesia teams results in improved organ transplantation outcomes and provides a foundation for developing new standards for other subspecialties in anesthesiology, critical care, and medicine overall. Through a century of discovery, the success we enjoy at the present time is the result of the work of well-organized multidisciplinary teams following standardized protocols and thereby saving thousands of lives worldwide each year. With continuing innovation, the future is bright.

Abstract
BACKGROUND Early extubation in liver transplantation (LT) and its potential benefits such as reduction in pulmonary complications and enhanced postoperative recovery have been described. The extent of the effect of early extubation on short-term outcomes after LT across the published literature is to the best of our knowledge unknown. OBJECTIVES The objective of this systematic review and meta-analysis was to determine whether early extubation improves immediate and short-term outcomes after LT and to provide expert recommendations. DATA SOURCES Ovid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central. METHODS A systematic review and meta-analysis on short-term outcomes after early extubation in LT was performed (CRD42021241402), following PRISMA guidelines and quality of evidence (QOE) and recommendations grading using the GRADE approach, derived from an international experts panel. Endpoints were reintubation rates, pulmonary and other complications/organ dysfunction, intensive care unit (ICU) and hospital length of stay (LOS). RESULTS Of 831 screened articles, 20 observational studies with a total of 3573 patients addressing early extubation protocols were included, of which 12 studies compared results after early versus deferred extubation. Reintubation and pulmonary complication rates were lower in the early versus deferred extubation groups (OR 0.29, CI 0.22-0.39; OR 0.17, CI 0.09-0.33, respectively). ICU and hospital LOS were shorter in eight out of eight and seven out of eight comparative studies, respectively. CONCLUSIONS Early extubation after LT is associated with improved short-term outcomes after LT and should be performed in the majority of patients (QOE; Moderate to low | Grade of Recommendation; Strong). Randomized controlled trials using standardized definitions of early extubation and short-term outcomes are needed to demonstrate causality, validate and allow comparability of the results.

Abstract
Perioperative care of patients undergoing liver transplantation (LT) is very complex. Metabolic derangements, hypothermia, coagulopathy and thromboses, severe infections, and graft dysfunction can affect outcomes. In this manuscript, we discuss several perioperative problems that can be encountered in LT recipients. The authors present the most up-to-date information regarding predicting and treating hemodynamic instability, coagulation monitoring and management, postoperative ventilation strategies and early extubation, management of infections, and ESLD-related pulmonary complications. In addition, early post-transplant allograft dysfunction will be discussed.

Abstract
BACKGROUND Fast-track anesthesia in liver transplantation (LT) has been discussed over the past few decades; however, factors associated with immediate extubation after LT surgery are not well defined. This study aimed to identify predictive factors and examine impacts of immediate extubation on post-LT outcomes. METHODS A total of 279 LT patients between January 2014 and May 2017 were included. Primary outcome was immediate extubation after LT. Other postoperative outcomes included reintubation, intensive care unit stay and cost, pulmonary complications within 90 days, and 90-day graft survival. Logistic regression was performed to identify factors that were predictive for immediate extubation. A matched control was used to study immediate extubation effect on the other postoperative outcomes. RESULTS Of these 279 patients, 80 (28.7%) underwent immediate extubation. Patients with anhepatic time >75 minutes and with total intraoperative blood transfusion ≥12 units were less likely to be immediately extubated (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.26-0.89; P = 0.02; OR, 0.11; 95% CI, 0.05-0.21; P < 0.001). The multivariable analysis showed immediate extubation significantly decreased the risk of pulmonary complications (OR, 0.34; 95% CI, 0.15-0.77; P = 0.01). According to a matched case-control model (immediate group [n = 72], delayed group [n = 72]), the immediate group had a significantly lower rate of pulmonary complications (11.1% versus 27.8%; P = 0.012). Intensive care unit stay and cost were relatively lower in the immediate group (2 versus 3 d; P = 0.082; $5700 versus $7710; P = 0.11). Reintubation rates (2.8% versus 2.8%; P > 0.9) and 90-day graft survival rates (95.8% versus 98.6%; P = 0.31) were similar. CONCLUSIONS Immediate extubation post-LT in appropriate patients is safe and may improve patient outcomes and resource allocation.

Abstract
Background Early tracheal extubation of recipients following liver transplantation (LT) has been gradually replacing the standard postoperative prolonged mechanical ventilation, contributing to better patient and graft survival and reduced costs. There are no universally accepted predictors of the success of immediate extubation in LT recipients. We hypothesized several potential predictors of successful immediate tracheal extubation in living donor liver transplantation (LDLT) recipients. Aim Evaluation of the validity of the following hypothesized factors: model for end-stage liver disease (MELD) score, duration of surgery, number of intraoperatively transfused packed red blood cells (RBCs) units, and end of surgery (EOS) serum lactate, as predictors of success of immediate tracheal extubation in living donor liver transplantation (LDLT) recipients. Methods In this prospective clinical investigation, perioperative data of adult living donor liver transplantation (LDLT) recipients were recorded. “Immediate extubation” was defined as tracheal extubation immediately and up to 1 hour post-transplant in the operating room. Patients were divided into the extubated group who were successfully extubated with no need for reintubation, and the non-extubated group who failed to meet the criteria of extubation, or were re-intubated within 4 hours of extubation. Results We enrolled 64 patients candidates for LDLT; 50 patients (76.9%) in group 1 were extubated early after LDLT while 14 patients (23.07%) in group 2 were transferred to the intensive care unit intubated. After data analysis, we found that EOS serum lactate, duration of surgery and number of packed RBCs units transfused intraoperatively were good predictors of success of immediate extubation (p < 0.001). MELD scores did not show any significant impact on the results (p = 0.54). Other factors such as EOS urine output and blood gases indices were shown to have a significant effect on the decision of extubation (p = 0.03 and 0.006, respectively). Conclusions EOS serum lactate, duration of surgery and number of packed RBCs units transfused were potential predictors of post-transplant early extubation.

Abstract
OBJECTIVES Acute kidney injury is a significant cause of morbidity after orthotopic liver transplant. Early extubation after liver transplant may have a beneficial effect on postoperative renal function. This may be the result of reduction in vasopressor-mediated vasoconstriction used to counteract the hypotension associated with sedative use and the effects of positive-pressure ventilation. Previous studies explored advantages of early extubation after liver transplant but focused on resource usage rather than clinical benefit. This study was designed to determine the association between fast-track extubation and reduction in postoperative vasopressor requirement and whether this had any association with acute kidney injury incidence or renal replacement therapy requirement. MATERIALS AND METHODS Data were collected from 144 orthotopic liver transplants. A propensity-matched case-control analysis was conducted on a subgroup of 33 patients who were fast-track extubated and with 33 propensity score-matched control patients who were not. The primary outcome was median days of postoperative vasopressor use, and secondary outcomes included incidence of acute kidney injury, renal replacement therapy requirement, and critical care admission duration. RESULTS The fast-track extubation group had a shorter postoperative vasopressor requirement (0 vs 2 days; P < .01) and a reduced need for renal replacement therapy (3% vs 21.2%; P = .05). Median critical care admission duration (3 vs 4 days; P = .03) and hospital admission duration (14 vs 19 days; P = .04) were shorter in the fast-track extubation group. CONCLUSIONS This is the first study to reveal a significant association between fast-track extubation and reduced postoperative vasopressor requirement. Additionally, this was associated with a trend toward reduced renal replacement requirement after liver transplant. It suggests that early extubation may not just be a resource benefit to an institution but may convey a clinical benefit to patients through a reduction in organ failure and requirement for organ support.

Abstract
There is a growing support for the use of protocols that incorporate multiple steps aimed at reducing the time patients require to regain health. A recurring limitation is the variable outcomes of these protocols with more or less success at the sites at which they are instituted. This review examines the essential building blocks needed to launch a successful ERAS protocol. It addresses why there are differences in outcome measures between centers such as the length of stay and the cost of care even if the protocols and patient populations are similar.

Abstract
BACKGROUND Early extubation after liver transplantation is safe and accelerates patient recovery. Patients with end-stage liver disease undergo sarcopenic changes, and sarcopenia is associated with postoperative morbidity and mortality. We investigated the impact of core muscle mass on the feasibility of immediate extubation in the operating room (OR) after living donor liver transplantation (LDLT). METHODS A total of 295 male adult LDLT patients were retrospectively reviewed between January 2011 and December 2017. In total, 40 patients were excluded due to emergency surgery or severe encephalopathy. A total of 255 male LDLT patients were analyzed in this study. According to the OR extubation criteria, the study population was classified into immediate and conventional extubation groups (39.6 vs. 60.4%). Psoas muscle area was estimated using abdominal computed tomography and normalized by height squared (psoas muscle index [PMI]). RESULTS There were no significant differences in OR extubation rates among the five attending transplant anesthesiologists. The preoperative PMI correlated with respiratory performance. The preoperative PMI was higher in the immediate extubation group than in the conventional extubation group. Potentially significant perioperative factors in the univariate analysis were entered into a multivariate analysis, in which preoperative PMI and intraoperative factors (i.e., continuous renal replacement therapy, significant post-reperfusion syndrome, and fresh frozen plasma transfusion) were associated with OR extubation. The duration of ventilator support and length of intensive care unit stay were shorter in the immediate extubation group than in the conventional extubation group, and the incidence of pneumonia and early allograft dysfunction were also lower in the immediate extubation group. CONCLUSIONS Our study could improve the accuracy of predictions concerning immediate post-transplant extubation in the OR by introducing preoperative PMI into predictive models for patients who underwent elective LDLT.

Abstract
INTRODUCTION To systematically compare immediate postoperative tracheal extubation (IPTE) with conventional tracheal extubation (CTE) and to determine whether IPTE can achieve an enhanced recovery for adult patients underwent liver transplantation (LT) without additional risks. We designed a systematic review and meta-analysis. METHODS The RCTs, cohorts, case-controls, or case series that explored outcomes of IPTE after LT for adults were involved in our study. The Newcastle-Ottawa scale was used to assess the risk of bias. RESULTS A total of 15 studies (n = 4144) were included, consisting of 10 studies (retrospective cohorts; n = 3387) for quantitative synthesis and 5 studies (1 prospective cohort, and 4 case series; n = 757) for qualitative synthesis. The pooled estimates suggested IPTE could reduce time to discharge from ICU stay (TDICU) (mean difference [MD] -2.12 days, 95% confidence interval [CI] -3.04 to -1.19 days), time to discharge from the hospital (TDH) (MD -6.43 days, 95% CI -9.53 to -3.33 days), re-intubation rate (RI) (odds ratio [OR] 0.29, 95% CI 0.22-0.39), morbidity rate (MR) (OR 0.15, 95% CI 0.08-0.30) and graft dysfunction rate (GD) (IPTE vs CTE: 0.3% vs 3.8%, P < .01), and had comparable ICU survival rate (ICUS) (OR 6.67 95% CI 1.34-33.35) when compared with CTE after LT. CONCLUSIONS IPTE can achieve an enhanced recovery for adult patients underwent LT without additional re-intubation, morbidity, and mortality risks. However, further work needs to be done to establish the extent definitively through carefully designed and conducted RCTs.

Abstract
A body of scientific studies has shown that early extubation is safe and cost-effective in a large number of liver transplant (LT) recipients including pediatric patients. However, fast-track practices are not universally accepted, and debate still lingers about whether these interventions are safe and serve the patients' best interest. In this article, we focus on reasons why physicians still have a persistent, although diminishing, reluctance to adopt fast-track protocols. We stress the importance of collection/analysis of perioperative data, adoption of a consensus-based standardized protocol for perioperative care, and formation of LT anesthesia focused teams and leadership. We conclude that the practice of early extubation and fast-tracking after LT surgery could help improve anesthesia performance, safety, and cost-effectiveness.

Abstract
Background and Aims: Fast tracking (FT) for more efficacious use of resources may be difficult after living donor liver transplantation (LDLT) due to a partial liver graft, complex vascular anastomoses and longer operating time. Our study was aimed at reporting our experience with FT (on table extubation) in LDLT recipients. A secondary objective of our study was to look at defining a subgroup of patients who could be prospectively planned for FT. Methods: We studied the demographics and outcomes of 15 LDLT recipients extubated immediately in the operating suite based on an uneventful intraoperative course, haemodynamic stability after graft reperfusion and improvement of metabolic parameters post-implantation and vascular anastomoses. Results: Twelve recipients were males, and mean age, body mass index (BMI) and Model for End Stage Liver Disease (MELD) score were 43 ± 12 years, 23 ± 3 kg/m2 and 15.5 ± 6, respectively, most were Child–Turcotte–Pugh Class B. Diabetes and hypothyroidism were present in 1 and 2 patients, respectively. Post-extubation, none required immediate re-intubation and one patient needed non-invasive ventilation for 2 h. Conclusion: Fast tracked recipients were young, with a low BMI, low MELD scores, minimal comorbidities and good immediate graft function post-reperfusion.

Abstract
The postoperative management of patients immediately after liver transplantation requires knowledge of this complex surgery and the physiology that accompanies liver failure. A multidisciplinary approach to the care of these patients is essential in order to reduce postoperative complications and preserve function in the transplanted organ. By their nature, patients undergoing liver transplantation have complicated medical problems before surgery which must be borne in mind when managing them after surgery. Haemorrhage, haemodynamic instability, acute renal failure, hepatic artery thrombosis and primary graft non-function are some of the complications that clinicians must be prepared for in the first days after transplantation. Pre-empting complications and acting rapidly to overt them is likely to have a considerable positive impact in these patients.

Abstract
With the evolution of surgical and anesthetic techniques, liver transplantation has become "routine," allowing for modifications of practice to decrease perioperative complications and costs. There is debate over the necessity for intensive care unit admission for patients with satisfactory preoperative status and a smooth intraoperative course. Postoperative care is made easier when the liver graft performs optimally. Assessment of graft function, vigilance for complications after the major surgical insult, and optimization of multiple systems affected by liver disease are essential aspects of postoperative care. The intensivist plays a vital role in an integrated multidisciplinary transplant team.

Abstract
This article addresses postoperative analgesia in patients with end-stage liver disease who have undergone liver transplantation (LT). Postoperative analgesia determines how patients perceive LT. Although important, this topic is underrepresented in the current literature. With an increased frequency of fast tracking in LT, efficient intra- and postoperative analgesia are undergoing changes. We herein review the current literature, compare the benefits and disadvantages of the therapeutic options, and make recommendations based on the current literature and clinical experience.

Abstract
BACKGROUND The extubation phase is an extremely critical moment in patients who have undergone orthotopic liver transplantation, who do not always have the advantage of long-lasting positive-pressure ventilation and positive expiratory end pressure; these factors can lead to splanchnic venous congestion, and this is why a rapid extubation can represent a great benefit for the graft. METHODS The aim of this study was to compare the adaptive support ventilation (ASV) mode with the standard mode of weaning in our intensive care unit, synchronized intermittent mandatory ventilation with pressure support (P-SIMV), in patients who received orthotopic liver transplantation. ASV is a positive-pressure mode, in which pressure level and respiratory rate are automatically adjusted according to measured lung dynamics at each breath. Eligible patients were assigned to either ASV or P-SIMV group. The weaning protocol was based on the individual respiratory activity and structured in 4 different phases. RESULTS The average length of intubation was significantly shorter in the ASV group than in the P-SIMV group (90±13 vs 153±22 minutes, P=.05). The total modifications to the ventilator settings were significantly larger in the P-SIMV group (1.5±1 vs 6±2; P=.003). CONCLUSIONS Our results suggest that although both procedures are safe and easy to apply, ASV is superior in terms of weaning times, and it simplifies respiratory management. The better patient-machine interaction in ASV has been highlighted by other authors for different clusters of patients.

Abstract
Background Acute liver failure (ALF) is a rapidly progressing and fatal disease for which liver transplantation (LT) is the only treatment. Posttransplant mechanical ventilation tends to be more prolonged in patients with ALF than in other LT patients. The present study examined the clinical effects of prolonged posttransplant mechanical ventilation (PMV), and identified risk factors for PMV following LT for ALF. Methods We reviewed data of patients undergoing LT for ALF between January 2005 and June 2011. After grouping patients according to administration of PMV (≥ 24 h), donor and recipient perioperative variables were compared between the groups with and without PMV. Potentially significant factors (P < 0.1) from the univariate intergroup comparison were entered into a multivariate logistic regression to establish a predictive model for PMV. Results Twenty-four (25.3%) of 95 patients with ALF who received PMV had a higher mortality rate (29.2% vs 11.3%, P = 0.038) and longer intensive care unit stay (12.9 ± 10.4 vs 7.1 ± 2.7 days, P = 0.012) than patients without PMV. The intergroup comparisons revealed worse preoperative hepatic conditions, more supportive therapy, and more intraoperative fluctuations in vital signs and less urine output in the with- compared with the without-PMV group. The multivariate analysis revealed that preoperative hepatic encephalopathy (≥ grade III), intraoperative blood pressure fluctuation, and oliguria (< 0.5 ml/kg/h) were independent risk factors for PMV. Conclusions PMV was associated with deleterious outcomes. Besides care for known risk factors including hepatic encephalopathy, meticulous attention to managing intraoperative hemodynamic circulatory status is required to avoid PMV and improve the posttransplant prognosis in ALF patients.

Abstract
Survival of critically ill patients is significantly affected by prolonged ventilation. The goal of this study was the development of a respiratory risk score (RRS) for the prediction of 3-month mortality and prolonged ventilation after liver transplantation (LT). Two hundred fifty-four consecutive LT patients from a single center were retrospectively randomized into a training group for model design and a validation group. A receiver operating characteristic (ROC) curve analysis was used to test sensitivity and specificity. The accuracy of the predictions was assessed with the Brier score, and the model calibration was assessed with the Hosmer-Lemeshow test. Cutoff values were determined with the best Youden index. The RRS was calculated in the first 24 hours as follows: (laboratory Model for End-Stage Liver Disease score > 30 = 2.36 points) + (fresh frozen plasma > 13.5 U = 2.70 points) + (partial pressure of arterial oxygen/fraction of inspired oxygen ratio < 200 mm Hg = 2.23 points) + (packed red blood cells > 10.5 U = 3.50 points) + (preoperative mechanical ventilation = 3.87 points) + (preoperative dialysis = 2.83 points) + (donor steatosis hepatis > 40% = 2.95 points). The RSS demonstrated high predictive accuracy, good model calibration, and c statistics > 0.7 in the training and validation groups. The RSS was able to predict 3-month mortality [cutoff = 6.64, area under the (ROC) curve (AUROC) = 0.794] and prolonged ventilation (cutoff = 3.69, AUROC = 0.798) with sensitivities of 69% and 81%, specificities of 83% and 73%, and overall model correctness of 76% and 77%, respectively. In conclusion, this study provides the first prognostic model for the prediction of 3-month mortality and prolonged ventilation after LT with high sensitivity and specificity and good model accuracy. The application of the RRS to an external cohort would be desirable for its further validation and introduction as a clinical tool for intensive care resource planning and prognostic decision making.

Abstract
BACKGROUND Anesthetic practices such as early tracheal extubation facilitate postoperative recovery. Early extubation after liver transplantation has been adopted by some centers in the recent two decades. No universal clinical guidelines are used and questions remain. This review aimed to address the current status of early extubation after liver transplantation. DATA SOURCES A literature search of MEDLINE and ISI Web of Knowledge databases was performed using terms such as liver transplantation, early extubation, immediate tracheal extubation, fast tracking or fast track anesthesia and postoperative tracheal extubation. Additional papers were identified by a manual search of the references in the key articles. RESULTS Review of the available literature provided an insight into the definition, evolution, advantages and risks of early extubation, and anesthetic techniques that prompt early extubation in liver transplant patients. Early extubation has proved to be feasible and safe in these patients, but the outcomes are still uncertain. CONCLUSIONS Early extubation after liver transplantation is feasible, safe and cost-effective in the majority of patients and has been increasingly accepted as an option for conventional postoperative ventilation. Comprehensive and individualized evaluation of the patient's condition before extubation by an experienced anesthesiologist is the cornerstone of success. Understanding of its effect on the outcome remains incomplete. In the future, additional trials are required to establish universal early extubation guidelines and to determine its benefits for patients and practitioners.

Pre-operative risk factors predict post-operative respiratory failure after liver transplantation. PLoS One 2011; 6:e22689.

Abstract
Objective Post-operative pulmonary complications significantly affect patient survival rates, but there is still no conclusive evidence regarding the effect of post-operative respiratory failure after liver transplantation on patient prognosis. This study aimed to predict the risk factors for post-operative respiratory failure (PRF) after liver transplantation and the impact on short-term survival rates. Design The retrospective observational cohort study was conducted in a twelve-bed adult surgical intensive care unit in northern Taiwan. The medical records of 147 liver transplant patients were reviewed from September 2002 to July 2007. Sixty-two experienced post-operative respiratory failure while the remaining 85 patients did not. Measurements and Main Results Gender, age, etiology, disease history, pre-operative ventilator use, molecular adsorbent re-circulating system (MARS) use, source of organ transplantation, model for end-stage liver disease score (MELD) and Child-Turcotte-Pugh score calculated immediately before surgery were assessed for the two groups. The length of the intensive care unit stay, admission duration, and mortality within 30 days, 3 months, and 1 year were also evaluated. Using a logistic regression model, post-operative respiratory failure correlated with diabetes mellitus prior to liver transplantation, pre-operative impaired renal function, pre-operative ventilator use, pre-operative MARS use and deceased donor source of organ transplantation (p<0.05). Once liver transplant patients developed PRF, their length of ICU stay and admission duration were prolonged, significantly increasing their mortality and morbidity (p<0.001). Conclusions The predictive pre-operative risk factors significantly influenced the occurrence of post-operative respiratory failure after liver transplantation.

Abstract
The majority of patients who undergo liver transplantation (LT) spend some time in the intensive care unit during the postoperative period. For some, this is an expected part of the immediate posttransplant recovery period, whereas for others, the stay is more prolonged because of preexisting conditions, intraoperative events, or postoperative complications. In this review, 4 topics that are particularly relevant to the postoperative intensive care of LT recipients are discussed, with an emphasis on current knowledge specific to this patient group. Infectious complications are the most common causes of early posttransplant morbidity and mortality. The common patterns of infection seen in patients after LT and their management are discussed. Acute kidney injury and renal failure are common in post-LT patients. Kidney injury identification, etiologies, and risk factors and approaches to management are reviewed. The majority of patients will require weaning from mechanical ventilation in the immediate postoperative period; the approach to this is discussed along with the approach for those patients who require a prolonged period of mechanical ventilation. A poorly functioning graft requires prompt identification and appropriate management if the outcomes are to be optimized. The causes of poor graft function are systematically reviewed, and the management of these grafts is discussed.

Abstract
Liver transplantation for end-stage liver disease results in excellent outcomes. Patient and graft outcome is closely monitored on a national level, and 1-year survival is between 80% and 95%. Liver transplantation relies on a multidisciplinary approach, with close involvement of anesthesiologists and intensivists. However, intraoperative care of these patients remains inconsistent and is highly institution dependent. This brief-review article will focus on controversial topics of intraoperative care. Existing evidence on intraoperative monitoring, intraoperative fluid and transfusion management, electrolyte and glucose management, postoperative patient disposition, and, lastly, anesthesia team management will be reviewed.

Abstract
BACKGROUND Early extubation after liver transplantation (LT) is an increasingly applied safe practice. The aim of the present study was to provide a simple extubation rule for accelerated weaning in the operating room (OR). METHODS Data of 597 patients transplanted at the LT center of Turin (Italy) were retrospectively analyzed. Fifty-two nonextubated patients (excluding those with a scheduled early reoperation) were compared with 545 successfully extubated patients (not in need of reintubation within the first 48 h). Significant variables at univariate analysis were entered into a logistic regression model and the regression coefficients of independent predictors were used to yield a prognostic score called the safe operating room extubation after liver transplantation (SORELT) score. RESULTS Two major and three minor criteria were found. The major ones were blood transfusions (higher than/or equal to 7 U of packed red blood cells) and end of surgery lactate (higher than/or equal to 3.4 mmol/l). The minor ones were status before LT (home vs. hospitalized patient), duration of surgery (longer than/or equal to 5 h), vasoactive drugs at the end of surgery (dopamine higher than 5 microg/kg/min or norepinephrine higher than 0.05 microg/kg/min). Patients who fulfill the SORELT score-derived criteria (fewer than two major/one major plus two minor/three minor criteria) can be considered for OR extubation. CONCLUSION Early extubation after LT requires a very careful assessment of the pre-operative, intraoperative, graft and post-operative care data available. The SORELT score helps as a simple and objective aid in considering such a decision.

Abstract
PURPOSE OF REVIEW The present review describes new trends and ongoing controversies in the anesthetic care of liver transplant recipients. RECENT FINDINGS Recent studies have improved our knowledge of conditions increasing perioperative risk, such as portopulmonary hypertension and renal failure. Improved surgical and anesthetic management has reduced intraoperative blood loss, as more studies identify an independent association between blood transfusion and poor outcome. New concepts in the coagulopathy of liver failure are emerging, with clear implications for clinical practice, including greater awareness of the risks of intraoperative thromboembolism. Less invasive intraoperative hemodynamic monitoring has been advocated, as has wider use of transoesophageal echocardiography. Early extubation is becoming more routinized. SUMMARY Anesthetic management still varies widely between liver transplant centers with little data to indicate best practice. Future research should focus on fluid replacement, prevention and treatment of coagulopathy, care of the acutely ill patient and the safety and benefits of early extubation.

Abstract
Small single-institutional studies performed prior to the introduction of organ allocation using the Model for End-Stage Liver Disease (MELD) suggest that early airway extubation of liver transplant recipients is a safe practice. We designed a multicenter study to examine adverse events associated with early extubation in patients selected for liver transplantation using MELD score. A total of 7 institutions extubated all patients meeting study criteria and reported adverse events that occurred within 72 hours following surgery. Adverse events were uncommon: occurring in only 7.7% of 391 patients studied. Most adverse events were pulmonary or surgically related. Pulmonary complications were usually minor, requiring only an increase in ambient oxygen concentration. The majority of surgical adverse events required additional surgery. Analysis of a limited set of perioperative variables suggest that blood transfusions and technical factors were associated with an increased risk of adverse events. In conclusion, while early extubation appears to be safe under specified circumstances, there are performance differences between institutions that remain to be explained.

Abstract
BACKGROUND AND OBJECTIVE Reducing postoperative mechanical ventilation in patients undergoing liver transplantation may have clinical and organizational advantages. On the basis of our experience, we here evaluate the possibility of practising immediate tracheal extubation in the operating theatre. METHODS In this prospective study, patients consecutively undergoing liver transplantation between 1 June 1999 and 31 May 2004 were extubated in the operating theatre at the end of surgery on the basis of standardized and universally accepted criteria, under conditions of haemodynamic and metabolic stability. RESULTS Two hundred and seven of the 354 patients (58.5%) were extubated immediately after the completion of the surgical procedure (mean time between end of surgery and extubation: 0.4 +/- 1.4 min); two were re-intubated. In the last of the 5 yr of the study, the percentage of immediate extubations increased to 82.5%. During the study period, there was a progressive increase in the number of immediate extubations per individual member of the team of anaesthetists. The pre-transplant Child-Pugh severity of the underlying liver disease did not predict rapid extubation, but the Model for End-stage Liver Disease score of < 11 did (receiver operator characteristic area under the curve = 0.61; P < 0.05). CONCLUSIONS Immediate extubation after liver transplantation is possible in a substantial percentage of cases; confidence, habit and a spirit of emulation are decisive factors in encouraging anaesthetists to extend this practice to the largest possible number of patients. A successful immediate extubation may be an important indicator of perioperative quality of care in liver transplantation.

Abstract
BACKGROUND AND OBJECTIVE Liver transplant is an effective procedure for fulminant hepatitis or chronic liver disease and offers an adequate quality of life. However, even though it is a consolidated treatment, patients can develop serious complications in the immediate postoperative course. PATIENTS AND METHOD Prospective observational study of 131 patients admitted in our intensive care unit after liver transplant surgery. We studied variables related with the development of complications and their relation to outcome. RESULTS Intensive care unit mortality was 11.5%. Median stay was 4 days. 90% of patients presented 2 or more complications. Hyperglycemia, thrombocytopenia and hypothermia were the most frequent complications but they were not related with mortality. Less frequent but related to outcome complications were acute renal failure (23.6% mortality vs. 1.3%; p < 0.01), ADRS (63.6% vs 6.7%; p < 0,01), low cardiac output (71.4% vs 4.3%; p < 0.01), > or = 2 vasoactive drugs (61.9% vs 1.8%; p < 0.01), encephalopathy (37.5% vs 9.8%; p < 0.05), pneumonia (80% vs 8%; p < 0.01) and hemorrhage (29.4% vs 8.8%; p < 0.05). Graph ischemia, coagulopathy, reperfusion syndrome and use of blood derivatives during surgery were factors related with the development of complications and mortality. Multivariate analysis showed a relationship with mortality and low cardiac output, number of vasoactive drugs and total time of graft ischemia. CONCLUSIONS Complications during the postoperative course of liver transplant are frequent but most of them have no effect on prognosis. The negative effect of severe complications should be limited by optimizing the hemodynamic support in these patients and minimizing ischemia of transplanted organs.

Abstract
INTRODUCTION Some groups have reported early extubation post-liver transplantation in patients with previously defined criteria, in an attempt to shorten the ICU stay and decrease costs. We review our experience with trends in mechanical ventilation and resource utilization. METHODS We retrospectively reviewed the length of mechanical ventilation, ICU stay, hospital stay, transfusions, and costs of liver transplants performed since the program's inception in 1993 and 2002 including 82 OLT in 71 patients. We also report our experience with immediate postoperative extubation, which we have done from October to December of 2002. We compare different periods: the early days (1993 to 1997), namely, fewer than 10 OLT per year, with the subsequent years assessed individually. RESULTS There has been a progressive decrease over time in the length of mechanical ventilation, ICU stay, hospital stay, and costs. Since the program's inception actuarial adult patient 1- and 5-year survival rates were 88.7% and 78%, respectively. The 1-year survival rate increased to 97% during the period of 2000 to 2002 (n = 30). From October to the present, we extubated four of seven adult patients who met criteria with none of them requiring reintubation. CONCLUSIONS We demonstrate improved results, decreased length of mechanical ventilation, ICU, and hospital stay, and costs. The immediate postoperative extubation may be feasible for patients who meet previously defined criteria.

Abstract
The management of patients for end-stage liver disease in the ICU mandates a multidisciplinary approach and intense monitoring. Orthotopic liver transplantation still remains the only definitive therapy. Given the increasing disparity between the number of potential recipients and available cadaver organs, the current challenge is to optimize outcome with the limited resource. In recent years, considerable progress has been made in developing specific and supportive medical measures. Future research should target a better understanding of mechanisms responsible for liver cell death and liver regeneration, as well as developments in xenotransplantation, hepatocyte transplantation, and liver-directed gene therapy.

Abstract
There is growing interest in measuring intra-abdominal pressure (IAP) in postsurgical and critically ill patients because increased pressure can impair various organs and functions. The aim of this study was to evaluate the effect of different IAP levels on the postoperative renal function of subjects undergoing orthotopic liver transplantation. IAP was measured every 8 hours with the urinary bladder pressure method for at least 72 hours after surgery. At the end of the study, the patients were classified on the basis of their IAP values: < or = 18 mm Hg (group A), 19 to 24 mm Hg (group B), > or = 25 mm Hg (group C). The three groups were compared in terms of the incidence of acute renal failure (defined as blood creatinine > 1.5 mg/dL or an increase in the same of > 1.1 mg/dL within 72 hours of surgery), hourly diuresis, blood creatinine, the filtration gradient, hemodynamic variations, and outcome. The incidence of renal failure was higher among the subjects in group C (P < .05 versus group A and < .01 versus group B), who also had higher creatinine levels (P < .01), a greater need for diuretics (P < .01) and a worse outcome (P < .05). Receiver Operator Characteristic curve analysis showed that an abdominal pressure of 25 mm Hg had the best sensitivity/specificity ratio for renal failure. An intra-abdominal pressure of > or = 25 mm Hg is an important risk factor for renal failure in subjects undergoing liver transplant.

Abstract
Fast tracking is an approach to health care delivery that emphasizes the efficient use of resources. This investigation was designed to determine whether shorter-acting drugs and different drug administration practices reduce the length of time for which patients require mechanical ventilation and intensive care after liver transplantation. After obtaining Institutional Review Board approval and informed consent, we randomized 80 consecutive patients (>17 years) undergoing liver transplantation to receive either our traditional anesthetic (thiopental, pancuronium, 50 microg/kg fentanyl), or fast track anesthetic (propofol, cisatracurium, 20 microg/kg fentanyl). The patients were weaned to extubation in the intensive care unit after an established clinical protocol. Measured data included the occurrence of intraoperative hypotension, intraoperative hypertension, intraoperative tachycardia, the length of postoperative mechanical ventilation, length of intensive care unit stay, and episodes of reintubation. Seventy-eight patients remained in the study through the investigation (two died intraoperatively). Operating time; amount of intraoperative red blood cells transfused; lowest body temperature achieved; and minutes of intraoperative hypotension, hypertension, and tachycardia were not different between the traditional and fast track patient groups. Postoperative ventilation time was greater in the patients who received the traditional anesthetic; mean. 1,081 minutes (median, 855) versus mean, 553.5 minutes (median, 390) (P <.001). However, there was no difference in length of intensive care unit stay. Five patients required reintubation (two patients given the traditional anesthetic, three given the fast track anesthetic). We conclude that a fast track approach to anesthetic care reduces the requirement for postoperative mechanical ventilation, but does not reduce intensive care unit stay after liver transplantation.

Abstract
Postoperative ventilation and admission to the intensive care unit (ICU) is the standard of care in liver transplantation and comprises a significant proportion of transplantation costs. Because immediate postoperative extubation has been reported previously in a selected group of liver transplant recipients, we questioned whether this protocol could be extended to a larger group of patients. We also sought to determine the proportion of patients extubated immediately after surgery that could be transferred to the surgical ward without intervening ICU care. Of 147 patients studied in a prospective trial of sequential liver transplant recipients (who were not second-transplant recipients, United Network for Organ Sharing status 1, living donor transplant recipients, or dead before the end of surgery), 13 patients did not meet postsurgical criteria for early extubation and 111 patients were successfully extubated. Eighty-three extubated patients were transferred to the surgical ward after a routine admission to the postoperative care unit. Only 3 patients who were transferred to the surgical ward experienced complications that required a greater intensity of nursing care. A learning curve detected during the 3-year study period showed that attempts to extubate increased from 73% to 96% and triage to the surgical ward increased from 52% to 82% without compromising patient safety. The use of this protocol in our institution resulted in a 1-day reduction in ICU use in 75.5% of study subjects. We therefore conclude that the majority of liver transplant recipients can be extubated safely and admitted to the surgical ward after liver transplantation surgery, thus decreasing the cost associated with ICU care.

Abstract
Part 1 of our report, presented in the same issue of the Journal, shows that immediate postoperative extubation and direct transfer to the surgical ward is safe and reduces reliance on the intensive care unit in most liver transplant recipients. However, there is no method to preoperatively predict which patients will need ventilatory support after surgery. To address this issue, we examined the relationship between perioperative patient attributes and extubation outcome in patients entered into our immediate postoperative extubation study from 1996 to 1998. Variables chosen stemmed from considerations in the literature. We examined the influence of 13 preoperative and 6 intraoperative factors on extubation outcome. Preoperative attributes included sex, race, diagnosis, United Network for Organ Sharing status, Child-Pugh score, presence of a portosystemic shunt, ascites, encephalopathy, coagulation, age, body mass index (BMI), creatinine level, and year of surgery. Intraoperative factors were type of surgery, surgeon, anesthesiologist, number of red blood cells administered, length of surgery, and surgical start time. Female sex (P =.02), BMI of 32 or greater (P =.015), portosystemic shunt (P =.022), and encephalopathy (P =.041) were associated with no attempt by the physician to extubate, whereas encephalopathy (P =.01) and BMI of 34 or greater (P =.002) were associated with failure to meet criteria for postoperative extubation (described in part 1 of this study). We conclude there are limited factors that predict an increased risk for postoperative respiratory failure in liver transplant recipients. Our results indicate that physicians are conservative in their approach to extubation immediately after surgery, and sole reliance on physician judgment to determine suitability for postoperative extubation leads to unnecessary use of postoperative cardiopulmonary support.
