Predictive role of hepatic venous pressure gradient in bleeding events among patients with cirrhosis undergoing orthotopic liver transplantation. JHEP Rep 2024; 6:101051. [PMID: 38699073 PMCID: PMC11060951 DOI: 10.1016/j.jhepr.2024.101051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Revised: 01/31/2024] [Accepted: 02/14/2024] [Indexed: 05/05/2024] Open
Abstract
Background & Aims Major bleeding events during orthotopic liver transplantation (OLT) are associated with poor outcomes. The proportion of this risk related to portal hypertension is unclear. Hepatic venous pressure gradient (HVPG) is the gold standard for estimating portal hypertension. The aim of this study was to analyze the ability of HVPG to predict intraoperative major bleeding events during OLT in patients with cirrhosis. Methods We retrospectively analyzed a prospective database including all patients with cirrhosis who underwent OLT between 2010 and 2020 and had liver and right heart catheterizations as part of their pre-transplant assessment. The primary endpoint was the occurrence of an intraoperative major bleeding event. Results The 468 included patients had a median HVPG of 17 mmHg [interquartile range, 13-22] and a median MELD on the day of OLT of 16 [11-24]. Intraoperative red blood cell transfusion was required in 72% of the patients (median 2 units transfused), with a median blood loss of 1,000 ml [575-1,500]. Major intraoperative bleeding occurred in 156 patients (33%) and was associated with HVPG, preoperative hemoglobin level, severity of cirrhosis at the time of OLT (MELD score, ascites, encephalopathy), hemostasis impairment (thrombocytopenia, lower fibrinogen levels), and complications of cirrhosis (sepsis, acute-on-chronic liver failure). By multivariable regression analysis with backward elimination, HVPG, preoperative hemoglobin level, MELD score, and tranexamic acid infusion were associated with the primary endpoint. Three categories of patients were identified according to HVPG: low-risk (HVPG <16 mmHg), high-risk (HVGP ≥16 mmHg), and very high-risk (HVPG ≥20 mmHg). Conclusions HVPG predicted major bleeding events in patients with cirrhosis undergoing OLT. Including HVPG as part of pre-transplant assessment might enable better anticipation of the intraoperative course. Impact and implications Major bleeding events during orthotopic liver transplantation (OLT) are associated with poor outcomes but the proportion of this risk related to portal hypertension is unclear. Our work shows that hepatic venous pressure gradient (HVPG), the gold standard for estimating portal hypertension, is a strong predictor of major bleeding events and blood loss volume in patients with cirrhosis undergoing OLT. Three groups of patients can be identified according to their risk of major bleeding events: low-risk patients with HVPG <16 mmHg, high-risk patients with HVPG ≥16 mmHg, and very high-risk patients with HVPG ≥20 mmHg. HVPG could be systematically included in the pre-transplant assessment to anticipate intraoperative course and tailor patient management.

Factors associated with mechanical ventilation longer than 24 h after liver transplantation in patients at risk for bleeding. BMC Anesthesiol 2023; 23:356. [PMID: 37919695 PMCID: PMC10621188 DOI: 10.1186/s12871-023-02321-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 10/24/2023] [Indexed: 11/04/2023] Open
Abstract
BACKGROUND This risk analysis aimed to explore all modifiable factors associated with prolonged mechanical ventilation (lasting > 24 h) after liver transplantation, based on prospectively collected data from a clinical trial. METHODS We evaluated 306 candidates. Ninety-three patients were excluded for low risk for transfusion (preoperative haemoglobin > 130 g.l-1), and 31 patients were excluded for anticoagulation therapy, bleeding disorders, familial polyneuropathy, or emergency status. Risk factors were initially identified with a log-binomial regression model. Relative risk was then calculated and adjusted for age, sex, and disease severity (Model for End-Stage Liver Disease [MELD] score). RESULTS Early tracheal extubation was performed in 149 patients (84.7%), and 27 patients (15.3%) required prolonged mechanical ventilation. Reoperations were required for 6.04% of the early extubated patients and 44% of patients who underwent prolonged ventilation (p = 0.001). A MELD score > 23 was the main risk factor for prolonged ventilation. Once modifiable risk factors were adjusted for MELD score, sex, and age, three factors were significantly associated with prolonged ventilation: tranexamic acid (p = 0.007) and red blood cell (p = 0.001) infusion and the occurrence of postreperfusion syndrome (p = 0.004). The median (IQR) ICU stay was 3 (2-4) days in the early extubation group vs. 5 (3-10) days in the prolonged ventilation group (p = 0.001). The median hospital stay was also significantly shorter after early extubation, at 14 (10-24) days, vs. 25 (14-55) days in the prolonged ventilation group (p = 0.001). Eight patients in the early-extubation group (5.52%) were readmitted to the ICU, nearly all for reoperations, with no between-group differences in ICU readmissions (prolonged ventilation group, 3.7%). CONCLUSION We conclude that bleeding and postreperfusion syndrome are the main modifiable factors associated with prolonged mechanical ventilation and length of ICU stay, suggesting that trials should explore vasopressor support strategies and other interventions prior to graft reperfusion that might prevent potential fibrinolysis.

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 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
There are parallels between the history of Enhanced Recovery after Surgery (ERAS) and liver transplantation. Both have been established and advanced by innovative individuals, often going against perceived wisdom and convention. Liver transplantation has traditionally been considered too complex for ERAS pathways, despite a small number of trials showing them to be both safe and of benefit. To date, there are very few randomized controlled trials and cohort studies publishing outcomes on liver transplant patients enrolled in comprehensive ERAS pathways. To progress our field, the 2022 International Liver Transplantation Society's Consensus Conference has created expert panels to analyze the evidence in 32 domains of the liver transplantation pathway using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach to generate expert recommendations. These recommendations will be voted on by the international community to gain consensus using the Danish model, and create the ERAS4OLT.org Enhanced Recovery after Liver Transplantation Pathway.

Abstract
BACKGROUND Enhanced Recovery After Surgery (ERAS) is a multimodal, evidence-based, program of care developed to minimize the response to surgical stress, associated with reduced perioperative morbidity and hospital stay. This study presents the specific ERAS Society recommendations for liver transplantation (LT) based on the best available evidence and on expert consensus. METHODS PubMed and ClinicalTrials.gov were searched in April 2019 for published and ongoing randomized clinical trials on LT in the last 15 y. Studies were selected by 5 independent reviewers and were eligible if focusing on each validated ERAS item in the area of adult LT. An e-Delphi method was used with an extended interdisciplinary panel of experts to validate the final recommendations. RESULTS Forty-three articles were included in the systematic review. A consensus was reached among experts after the second round. Patients should be screened for malnutrition and treated whenever possible. Prophylactic nasogastric intubation and prophylactic abdominal drainage may be omitted, and early extubation should be considered. Early oral intake, mobilization, and multimodal-balanced analgesia are recommended. CONCLUSIONS The current ERAS recommendations were elaborated based on the best available evidence and endorsed by the e-Delphi method. Nevertheless, prospective studies need to confirm the clinical use of the suggested protocol.

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 extubation of liver transplantation recipients is a cornerstone of fast-track (FT) pathways. Identifying suitable candidates has previously been accomplished using perioperative variables to develop a FT probability score. The objective of this study was to externally validate a proposed FT score. METHODS Following Research Ethics Board approval, data were extracted on liver transplants conducted at a single center from 2009 to 2017. Data extracted included patient characteristics, intraoperative variables, and postoperative outcome variables. The proposed FT score utilized 9 variables: age, gender, body mass index, model of end-stage liver disease, retransplant, preoperative hospital admission, blood transfusion, operative time, and vasopressor use. We calculated the FT score in our cohort, and assessed the discrimination and calibration of the model. Score performance was explored by subgroup analyses, customization and altering the outcome definition. RESULTS The FT score was found to predict higher rates of successful FT than was observed in the external cohort (n = 1385) and had reduced discrimination (area under the receiver operating curve, 0.711; 95% confidence interval, 0.682-0.741) compared with the original internal validation cohort (area under the receiver operating curve, 0.830; 95% confidence interval, 0.789-0.871; P < 0.0001). Discrimination was improved by customizing the transfusion (P < 0.0001) components of the simplified score or by level 1 customization of all regression model coefficients (P < 0.0001). A time-based definition of FT (early extubation) did not alter the accuracy of the prediction score (P = 0.914), improving the model's generalizability. CONCLUSIONS The proposed FT score may help identify patients suitable for early extubation and FT pathways after liver transplantation in conjunction with clinical judgment.

Enhanced recovery after surgery programs improve short-term outcomes after liver transplantation - A systematic review and meta-analysis. Clin Transplant 2021; 35:e14453. [PMID: 34382235 DOI: 10.1111/ctr.14453] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 07/26/2021] [Accepted: 08/01/2021] [Indexed: 11/28/2022]
Abstract
This systematic review aimed to investigate the available quality of evidence (QOE) of enhanced recovery after surgery (ERAS) for liver transplantation (LT) on short-term outcomes, grade recommendations and identify relevant components for ERAS protocols. A systematic review and meta-analysis were conducted on short-term outcomes after LT when applying comprehensive ERAS protocols (>1 ERAS component) versus control groups (CRD42021210374), following the GRADE approach for grading quality of evidence and strength of recommendations. Endpoints were morbidity, mortality, length of stay and readmission rates after ERAS for LT. Of 858 screened articles, two randomized controlled trials, 2 prospective and 1 retrospective cohort studies were included (2002 - 2020). Frequent ERAS components were early extubation and postoperative antibiotic, fluid and nutrition management. Overall complications were reduced in ERAS versus control cohorts (OR 0.4 (CI 0.2, 0.7), with no significant differences in mortality and hospital readmission rates. Intensive care unit and hospital length of stay were shorter in ERAS groups (percentage decrease, 55% and 29%, respectively). QOE for individual outcomes was rated moderate to low. ERAS protocols in LT are related to improved short-term outcomes after liver transplantation (Quality of Evidence; Moderate to low | Grade of Recommendation; Strong), but currently lack standardization.

Enhanced recovery in liver transplantation: A value-based approach to complex surgical care. Surgery 2021; 170:1830-1837. [PMID: 34340822 DOI: 10.1016/j.surg.2021.07.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Revised: 06/27/2021] [Accepted: 07/02/2021] [Indexed: 01/07/2023]
Abstract
BACKGROUND Value-based healthcare focuses on improving outcomes relative to cost. We aimed to study the impact of an enhanced recovery pathway for liver transplant recipients on providing value. METHODS In total, 379 liver recipients were identified: pre-enhanced recovery pathway (2017, n = 57) and post-enhanced recovery pathway (2018-2020, n = 322). The enhanced recovery pathway bundle was defined through multidisciplinary efforts and included optimal fluid management, end-of-case extubation, multimodal analgesia, and a standardized care pathway. Pre- and post-enhanced recovery pathway patients were compared with regard to extubation rates, lengths of stay, complications, readmissions, survival, and costs. RESULTS Pre- and post-enhanced recovery pathway recipient model for end-stage liver disease score and balance of risk scores were similar, although post-enhanced recovery pathway recipients had a higher median donor risk index (1.55 vs 1.39, P = .003). End-of-case extubation rates were 78% post-enhanced recovery pathway (including 91% in 2020) versus 5% pre-enhanced recovery pathway, with post-enhanced recovery pathway patients having decreased median intraoperative transfusion requirements (1,500 vs 3,000 mL, P < .001). Post-enhanced recovery pathway recipients had shorter median intensive care unit (1.6 vs 2.3 days, P = .01) and hospital stays (5.4 vs 8.0 days, P < .001). Incidence of severe (Clavien-Dindo ≥3) complications during the index hospitalization were similar between pre-enhanced recovery pathway versus post-enhanced recovery pathway groups (33% vs 23%, P = .13), as were 30-day readmissions (26% vs 33%, P = .44) and 1-year survival (93.0% vs 94.5%, P = .58). The post-enhanced recovery pathway cohort demonstrated a significant reduction in median direct cost per case ($11,406; P < .001). CONCLUSION Implementation of an enhanced recovery pathway in liver transplantation is feasible, safe, and effective in delivering value, even in the setting of complex surgical care.

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
INTRODUCTION Evidence suggests that immediate extubation after liver transplantation provides graft and economic benefits without compromising patient outcomes. This study tried to determine the incidence of immediate extubation, demonstrate related factors, and develop a predictive model from the significant factors. METHODS This retrospective descriptive study included 240 out of 271 liver transplantation patients in the hospital liver transplant registry between 2004 and 2016. Extubated and non-extubated groups were statistically compared. RESULTS The incidence of immediate extubation was 32.1%. It was associated with a MELD score ≤ 25 (adjusted OR, 5.17; 95% CI, 1.64-16.24; p = .005); packed red cells (PRC) transfusion ≤1600 ml (adjusted OR, 3.45; 95% CI, 1.82-6.53; p < .001); and no requirement for post-operative vasopressors (adjusted OR, 5.83; 95% CI, 2.30-14.77; p < .001). The immediate-extubation group had fewer complications and shorter hospital stays. A Siriraj Liver transplant Extubation Score (SLES) of 5 yielded the best prediction of safe immediate extubation. CONCLUSIONS An incidence of 32.1% was found for immediate extubation following liver transplantation. Associated factors were a MELD score ≤ 25, a lower amount of transfused blood, and no requirement for post-operative vasopressors. An SLES score of 5 predicted safe immediate extubation.

Abstract
Liver grafts from donation after circulatory death (DCD) are a source of organs to decrease wait-list mortality. While there have been lower rates of graft loss, there are concerns of an increased incidence of intraoperative events in recipients of DCD grafts. We aim to look at the incidence of intraoperative events between recipients of livers from DCD and donation after brain death (DBD) donors. We collected data for 235 DCD liver recipients between 2006 and 2017. We performed a 1:1 propensity match between these patients and patients with DBD donors. Variables included recipient age, liver disease etiology, biological Model for End-Stage Liver Disease (MELD) score, allocation MELD score, diagnosis of hepatocellular carcinoma, and year of transplantation. DCD and DBD groups had no significant differences in incidence of postreperfusion syndrome (P = 0.75), arrhythmia requiring cardiopulmonary resuscitation (P = 0.66), and treatments for hyperkalemia (P = 0.84). In the DCD group, there was a significant increase in amount of total intraoperative and postreperfusion blood products (with exception of postreperfusion packed red blood cells) utilized (P < 0.05 for all products), significant differences in postreperfusion thromboelastography parameters, as well as inotropes and vasopressors used (P < 0.05 for all infusions). There was no difference in patient (P = 0.49) and graft survival (P = 0.10) at 1, 3, and 5 years. In conclusion, DCD grafts compared with a cohort of DBD grafts have a similar low incidence of major intraoperative events, but increased incidence of transient vasopressor/inotropic usage and increased blood transfusion requirements. This does not result in differences in longterm outcomes. While centers should continue to look at DCD liver donors, they should be cognizant regarding intraoperative care to prevent adverse outcomes.

Abstract
In this paper we will describe anaesthetic management of solid organ and reconstructive transplantation (RT) patients. We will focus on similar underlying principles of reperfusion, ischaemic-reperfusion injury, preconditioning and extracorporeal donor organ preservation. Special concerns for anaesthetic management of these patients need to focus on pre-assessment, pre-operative optimisation, vascular access, fluid management, blood and products replacement, cardiovascular monitoring, use of inotropes and vasoconstrictors, maintaining electrolyte balance and regional anaesthesia. Despite the complexity and long duration of transplant procedures, fast-tracking to the surgical ward after transplantation is becoming more popular and its benefits are well recognised.

Abstract
Background: Fast-tracking is an approach adopted by Mayo Clinic in Florida's (MCF) liver transplant (LT) program, which consists of early tracheal extubation and transfer of patients to surgical ward, eliminating a stay in the intensive care unit in select patients. Since adopting this approach in 2002, MCF has successfully fast-tracked 54.3% of patients undergoing LT. Objectives: This study evaluated the reduction in post-operative length of stay (LOS) that resulted from the fast-tracking protocol and assessed the potential cost saving in the case of nationwide implementation. Methods: A propensity score for fast-tracking was generated based on MCF liver transplant databases during 2011-2013. Various propensity score matching algorithms were used to form control groups from the United Network of Organ Sharing Standard Analysis and Research (STAR) file that had comparable demographic characteristics and health status to the treatment group identified in MCF. Multiple regression and matching estimators were employed for evaluation of the post-surgery LOS. The algorithm generated from the analysis was also applied to the STAR data to determine the proportion of patients in the US who could potentially be candidates for fast-tracking, and the potential savings. Results: The effect of the fast-tracking on the post-transplant LOS was estimated at approximately from 2.5 (p-value = 0.001) to 3.2 (p-value < 0.001) days based on various matching algorithms. The cost saving from a nationwide implementation of fast-tracking of liver transplant patients was estimated to be at least $78 million during the 2-year period. Conclusion: The fast-track program was found to be effective in reducing post-transplant LOS, although the reduction appeared to be less than previously reported. Nationwide implementation of fast-tracking could result in substantial cost savings without compromising the patient outcome.

Abstract
PURPOSE Recovery after liver transplant (LT) requires extensive resources, including prolonged intensive care unit stays. The objective of this study was to use an assessment tool to determine if LT recipients remain in ICU beyond designated indications. METHODS Records from 100 consecutive LTs performed in a single institution were retrospectively reviewed. An admission, discharge, and triage screening (ADT) tool was utilized to assess the indications for each ICU day. Data collected included demographics; pre-, intra-, and post-operative course; and complications. Days not meeting ADT criteria were considered additional ICU days. RESULTS 100 patients: mean age 55 years (range 24-78 years) and mean MELD score 30 (range 6-47). Three recipients who died within one week were excluded. Forty-eight (49.5%) patients had a total of 75 additional days on initial ICU stay. Univariate analysis revealed no significant differences between patients with and without additional days. 12/97 (12.4%) patients returned to ICU including 5/48 and 7/49 with and without additional days. CONCLUSION Nearly half of the LT recipients remained in ICU an average of 1.6 additional days. Monitoring of organ function appeared to be the most common reason. Opportunities to improve resource utilization could include transfer to an intermediate/progressive care ("step-down") unit.

Abstract
OBJECTIVES This study evaluated the impact of psychiatric comorbidities in liver transplant (LT) recipients aged ≥65 years (elderly) on length of hospital-stay (LOS), death, and a composite outcome of graft loss or death. METHODS This retrospective study assessed impact of psychiatric comorbidities in 122 elderly LT recipients and a matched group of 122 LT recipients aged <65 years (younger). Associations were assessed using adjusted multivariable regression models. RESULTS Among elderly, median age at LT was 68 years, most were males (62%), white (85%) and 61.7% had a history of any psychiatric diagnosis. Among younger, median age was 55, most were males (67.2%), white (77.5%) and 61.5% had any psychiatric diagnosis. Median LOS was 8 days for both groups. Among elderly, after a median follow-up of 5 years, 25.4% died and 29.5% experienced graft loss or death. History of adjustment disorder, history of depression, past psychiatric medication use, and pain prior to LT were associated with an increased risk of death or the composite graft loss or death. Perioperative use of SSRIs and lack of sleeping medication use were associated with longer LOS. Among aged <65, after median follow-up of 4.7 years, 21 patients (17%) died and 25 (20%) experienced graft loss or death; history of depression, perioperative SSRIs or sleeping medications use was associated with increased mortality and graft-loss or death. CONCLUSION Six out of 10 patients among both elderly and younger cohorts had pre-LT psychiatric comorbidities, some of which adversely affected outcomes after LT.

Abstract
The critical care involved in solid-organ transplantation (SOT) is complex. Pre-, intra- and post-transplant care can significantly impact both – patients’ ability to undergo SOT and their peri-operative morbidity and mortality. Much of the care necessary for medical optimization of end-stage organ failure (ESOF) patients to qualify and then successfully undergo SOT, and the management of peri-operative and/or long-term complications thereafter occurs in an intensive care unit (ICU) setting. The current literature specific to critical care in abdominal SOT patients was reviewed. This paper provides a contemporary perspective on the potential multifactorial advantages of sub-specialized transplant critical care units in providing efficient, comprehensive, and collaborative multidisciplinary care.

Abstract
Chronic liver disease has been associated with pulmonary dysfunction both before and after liver transplantation. Post-liver transplantation pulmonary complications can affect both morbidity and mortality often necessitating intensive care during the immediate postoperative period. The major pulmonary complications include pneumonia, pleural effusions, pulmonary edema, and atelectasis. Poor clinical outcomes have been known to be associated with age, severity of liver dysfunction, and preexisting lung disease as well as perioperative events related to fluid balance, particularly transfusion and fluid volumes. Delineating each and every one of these pulmonary complications and their associated risk factors becomes paramount in guiding specific therapeutic strategies.

Abstract
BACKGROUND Prolonged initial intensive care unit (ICU) stay after liver transplantation (LT) is associated with prolonged total hospitalization, increased hospital mortality, and impaired patient and graft survival. Recent data suggested that model for end-stage liver disease (MELD) score at the time of LT and the length of surgery were the two independent risk factors for an ICU stay longer than 3 days after LT. We further identified factors influencing prolonged ICU stay in single-center liver graft recipients. PATIENTS AND METHODS One hundred fifty consecutive LT recipients (M/F 94/56, median age 55 (range, 39-60), 36% with viral hepatitis, were prospectively enrolled into the study. Associations between clinical factors and prolonged ICU stay were evaluated using logistic regression models. Receiver operating characteristic curves were analyzed to determine the appropriate cutoffs for continuous variables. Threshold for significance was P ≤ .05. RESULTS Highly prolonged (≥8 days) and moderately prolonged (≥6 days) postoperative ICU stay was noted in 19 (12.7%) and 59 (39.3%) patients, respectively. Serum bilirubin (P = .001) and creatinine concentrations (P = .011), international normalized ratio (P = .004), and sodium-MELD (P < .001) were all significantly associated with postoperative intensive care unit stay over or equal to 75th percentile (6 days). Sodium-MELD was significantly associated with postoperative care unit stay greater or equal to the 90th percentile (8 days; P = .018). CONCLUSIONS Sodium-MELD might be a novel risk factor of prolonged ICU stay in this single-center experience.

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 We evaluated patient characteristics of live donor liver transplant (LDLT) recipients undergoing a fast-track protocol without intensive care unit (ICU) admission versus LDLT patients receiving posttransplant ICU care. Methods Of the 153 LDLT recipients, 46 patients were included in our fast-track protocol without ICU admission. Both, fast-tracked patients and ICU-admitted patients were compared regarding donor and patient characteristics, perioperative characteristics, and postoperative outcomes and complications. In a subgroup analysis, we compared fast-tracked patients with patients who were admitted in the ICU for less than 24 hours. Results Fast-tracked versus ICU patients had a lower model for end-stage liver disease score (13 ± 4 vs 18 ± 7; P < 0.0001), lower preoperative bilirubin levels (51 ± 50 μmol/L vs 119.4 ± 137.3 μmol/L; P < 0.001), required fewer units of packed red blood cells (1.7 ± 1.78 vs 4.4 ± 4; P < 0.0001), and less fresh-frozen plasma (2.7 ± 2 vs 5.8 ± 5; P < 0.0001) during transplantation. Regarding postoperative outcomes, fast-tracked patients presented fewer bacterial infections within 30 days (6.5% [3] vs 29% [28]; P = 0.002), no episodes of pneumonia (0% vs 11.3% [11]; P = 0.02), and less biliary complications within the first year (6% [3] vs 26% [25]; P = 0.001). Also, fast-tracked patients had a shorter posttransplant hospital stay (10.8 ± 5 vs 21.3 ± 29; P = 0.002). In the subgroup analysis, fast-tracked vs ICU patients admitted for less than 24 hours had lower requirements of packed red blood cells (1.7 ± 1.78 vs 3.9 ± 4; P = 0.001) and fresh-frozen plasma (2.7 ± 2 vs 5.8 ± 4.5; P = 0.0001). Conclusions Fast-track of selected patients after LDLT is safe and feasible. An objective score to perioperatively select LDLT recipients amenable to fast track is yet to be determined.

Abstract
BACKGROUND Operative time often has been cited as an important factor for postoperative outcomes. Despite this belief, most efforts to improve liver transplant outcomes have largely focused on only patient and donor factors, and little attention has been paid on operative time. The primary objective of this project was to determine the impact of operative time on graft survival after liver transplant. METHODS A retrospective review of 2,877 consecutive liver transplants performed at a single institution was studied. Data regarding recipient, donor, and operative characteristics, including detailed granular operative times were collected prospectively and retrospectively reviewed. Using an instrument variable approach, Cox multivariate modeling was performed to assess the impact of operative time without the confounding of known and unknown variables. RESULTS Of the 2,396 patients who met the criteria for review, the most important factors determining liver transplant graft survival included recipient history of Hepatitis C (hazard ratio 1.45, P = .02), donor age (hazard ratio 1.23, P = .03), use of liver graft from donation after cardiac death donor (hazard ratio 1.50, P < .01), and operative time (hazard ratio 1.26, P = .01). In detailed analysis of stages of the liver transplant operation, the time interval from incision to anhepatic phase was associated with graft survival (hazard ratio 1.33; P = .02). CONCLUSION Using a novel instrument variable approach, we demonstrate that operative time (in particular, the time interval from incision to anhepatic time) has a significant impact on graft survival. It also seems that some of this efficiency is under the influence of the transplant surgeon.

Abstract
BACKGROUND & RATIONALE Limited information related to Liver Transplantation (LT) costs in South America exists. Additionally, costs analysis from developed countries may not provide comparable models for those in emerging economies. We sought to evaluate a predictive model of Early Discharge from Hospital after LT (ERDALT = length of hospital stay ≤ 8 days). A predictive model was assessed based on the odds ratios (OR) from a multivariate regression analysis in a cohort of consecutively transplanted adult patients in a single center from Argentina and internally validated with bootstrapping technique. RESULTS ERDALT was applicable in 34 of 289 patients (11.8%). Variables independently associated with ERDALT were MELD exception points OR 1.9 (P = 0.04), surgery time < 4 h OR 3.8 (P = 0.013), < 5 units of blood products consumption (BPC) OR 3.5 (P = 0.001) and early weaning from mechanical intubation OR 6.3 (P = 0.006). Points in the predictive scoring model were allocated as follows: MELD exception points (absence = 0 points, presence = 1 point), surgery time < 4 h (0-2 points), < 5 units of BPC (0-2 points), and early weaning (0-3 points). Final scores ranged from 0 to 8 points with a c-statistic of 0.83 (95% CI 0.77-0.90; P < 0.0001). Transplant costs were significantly lower in patients with ERDALT (median $23,078 vs. $28,986; P < 0.0001). Neither lower patient and graft survival, nor higher rates of short-term re-hospitalization and acute rejection events after discharge were observed in patients with ERDALT. In conclusion, the ERDALT score identifies patients suitable for early discharge with excellent outcomes after transplantation. This score may provide applicable models particularly for emerging economies.

Abstract
Liver transplantation has become an effective and valuable option for patients with end-stage liver disease and hepatocellular carcinoma. Liver failure, an acute or chronic condition, results in impaired bile production and excretion, clotting factor production, protein synthesis, and regulation of metabolism and glucose. Some acute conditions of liver disease have the potential to recover if the liver heals on its own. However, chronic conditions, such as cirrhosis, often lead to irreversible disease and require liver transplantation. In this publication, we review the pathophysiology of liver failure, examine common conditions that ultimately lead to liver transplantation, and discuss the postoperative management of patients who are either hemodynamically stable (type A) or unstable (type B).

Abstract
Early allograft dysfunction (EAD) after liver transplantation (LT) is related to ischemia-reperfusion injury and may lead to a systemic inflammatory response and extrahepatic organ dysfunction. We evaluated the effect of EAD on new-onset acute kidney injury (AKI) requiring renal replacement therapy within the first month and end-stage renal disease (ESRD) within the first year post-LT in 1325 primary LT recipients. EAD developed in 358 (27%) of recipients. Seventy-one (5.6%) recipients developed AKI and 38 (2.9%) developed ESRD. Compared with those without EAD, recipients with EAD had a higher risk of AKI and ESRD (4% vs. 9% and 2% vs. 6%, respectively, p < 0.001 for both). Multivariate logistic regression analysis showed an independent relationship between EAD and AKI as well as ESRD (odds ratio 3.5, 95% confidence interval 1.9-6.4, and odds ratio 3.1, 95% confidence interval 11.9-91.2, respectively). Patients who experienced both EAD and AKI had inferior 1-, 3-, 5-, and 10-year patient and graft survival compared with those with either EAD or AKI alone, while those who had neither AKI nor EAD had the best outcomes (p < 0.001). Post-LT EAD is a risk factor for both AKI and ESRD and should be considered a target for future intervention to reduce post-LT short- and long-term renal dysfunction.

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.
