Redefining Cirrhotic Cardiomyopathy for the Modern Era.

Cirrhotic cardiomyopathy (CCM) is cardiac dysfunction in patients with end-stage liver disease in the absence of prior heart disease. First defined in 2005 during the World Congress of Gastroenterology, CCM criteria consisted of echocardiographic parameters to identify subclinical cardiac dysfunction in the absence of overt structural abnormalities. Significant advancements in cardiovascular imaging over the past 14 years, including the integration of myocardial deformation imaging into routine clinical practice to identify subclinical cardiovascular dysfunction, have rendered the 2005 CCM criteria obsolete. Therefore, new criteria based on contemporary cardiovascular imaging parameters are needed. In this guidance document, assembled by a group of multidisciplinary experts in the field, new core criteria based on contemporary cardiovascular imaging parameters are proposed for the assessment of CCM. This document provides a critical assessment of the diagnosis of CCM and ongoing assessment aimed at improving clinical outcomes, particularly surrounding liver transplantation. Key points and practice-based recommendations for the diagnosis of CCM are provided to offer guidance for clinicians and identify gaps in knowledge for future investigations.

The perioperative management of simultaneous bilateral nephrectomy with renal transplantation: a case series.

PURPOSE: Bilateral nephrectomy is performed at times with renal transplantation. Though surgical indications and timing of these two procedures have been described, there are no large case series describing the anesthetic management of these cases. We sought to describe our experience. METHODS: We performed a historical cohort study on 54 consecutive cases of simultaneous bilateral nephrectomy with renal transplantation at a single, tertiary-care medical centre. Descriptive statistics were used. RESULTS: The most common etiology of kidney disease involved was autosomal dominant polycystic kidney disease at 52/54 (96%) cases. All patients received grafts from living donors. An arterial line was placed in 44 (81%) and a central venous catheter in 16 (30%) subjects. At least one vasopressor infusion was used in 44 (81%) cases and 37 (69%) patients required admission to the intensive care unit (ICU). Of this subset, 30 (81%) were admitted for ongoing vasopressor support and six (16%) for hemodynamic monitoring. All patients were extubated in the operating room upon completion of the procedure. Median [interquartile range (IQR)] ICU length of stay (LOS) was 0.9 [0.7-1.4] days and total hospital LOS was 4.4 [4.3-5.4] days. There were no cases of mortality at 30 days or of postoperative dialysis. CONCLUSIONS: Adult patients undergoing simultaneous bilateral nephrectomy with renal transplantation often developed perioperative hypotension requiring vasopressor infusions and postoperative transfer to the ICU. This is possibly due to a temporary loss of the renin-angiotensin system. Despite this, patients most commonly were transferred to the floor on postoperative day 1 and had successful outcomes with no mortality at 30 days.

RéSUMé: OBJECTIF: La néphrectomie bilatérale est parfois réalisée en même temps qu'une transplantation rénale. Bien que les indications chirurgicales et le moment de ces deux interventions aient été décrits, il n'existe aucune grande série de cas décrivant la prise en charge anesthésique de ces procédures. Notre objectif était de décrire notre expérience. MéTHODE: Nous avons réalisé une étude de cohorte historique sur 54 cas consécutifs de néphrectomie bilatérale avec transplantation rénale simultanée dans un seul centre médical de soins tertiaires. Des statistiques descriptives ont été utilisées. RéSULTATS: La maladie polykystique des reins autosomique dominante constituait l'étiologie de la maladie rénale la plus fréquente, représentant 52/54 (96 %) des cas. Tous les patients ont reçu des greffes de donneurs vivants. Une ligne artérielle a été installée chez 44 (81 %) patients et un cathéter veineux central chez 16 (30 %) patients. Au moins une perfusion de vasopresseurs a été utilisée chez 44 (81 %) patients, et 37 (69 %) patients ont dû être admis à l'unité de soins intensifs (USI). De ce sous-ensemble, 30 (81 %) patients ont été admis pour recevoir un soutien continu de vasopresseurs et six (16 %) pour un monitorage hémodynamique. Tous les patients ont été extubés en salle d'opération à la fin de l'intervention. La durée médiane [écart interquartile (ÉIQ)] de séjour aux soins intensifs était de 0,9 [0,7 à 1,4] jour, et la durée totale de séjour à l'hôpital était de 4,4 [4,3 à 5,4] jours. Il n'y a eu aucun cas de mortalité à 30 jours ou de dialyse postopératoire. CONCLUSION: Les patients adultes subissant une néphrectomie bilatérale et une transplantation rénale simultanées ont souvent souffert d'hypotension périopératoire exigeant des perfusions de vasopresseurs et un transfert postopératoire aux soins intensifs. Ceci est probablement dû à une perte temporaire du système rénine-angiotensine. Malgré cela, les patients étaient en général transférés à l'étage au jour postopératoire 1 et ont eu des devenirs favorables sans mortalité à 30 jours.

Anesthetic considerations for combined heart--liver transplantation in patients with Fontan-associated liver disease.

PURPOSE OF REVIEW: The success of the Fontan procedure has led to increased survival of patients born with certain congenital heart disease to the point that new sequlae, as a result of Fontan circulation, are being discovered. Included among these is Fontan-associated liver disease (FALD). The purpose of this review is to present available literature on the perioperative management of the combined heart--liver transplantation (CHLT) in patients with FALD. RECENT FINDINGS: The perioperative management of a combined heart-liver transplant in a patient with Fontan circulation is complex. The patient is at risk for hemodynamic disturbances, significant blood loss, coagulopathies, and metabolic derangements. The maintenance of an appropriate transpulmonary pressure gradient is paramount to success. Postoperative management should be accomplished by a multidisciplinary care team. Limited series have demonstrated good outcomes in patients who have undergone CHLT. SUMMARY: The perioperative management of CHLT in patients with FALD is complex and available literature is limited. Future studies are needed to further assess proper perioperative management of patients with FALD who undergo CHLT.

Changes in transfusion practice over time in adult patients undergoing liver transplantation.

OBJECTIVE: The aim of this study was to investigate changes in transfusion practice over time in liver transplantation surgery and to evaluate potential causes for changes in practice and report associated perioperative morbidity and mortality. DESIGN: A retrospective cohort study. SETTING: A single tertiary referral academic hospital. PARTICIPANTS: Two cohorts of 100 sequential adult primary liver transplant recipients: Early practice (1990-1991) and recent practice (2005-2006). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Perioperative transfusion and hemoglobin data were recorded. Mortality and postoperative complications were identified up to 30 days postoperatively. Appropriate intergroup statistical comparisons were made; p ≤ 0.05 was considered statistically significant. Compared with the early group, the recent group had significantly fewer perioperative allogeneic red blood cell transfusions, intraoperative autotransfusions, and transfusions of other blood products. No change in perioperative transfusion triggers was identified. There were no significant alterations in perioperative morbidity or mortality. CONCLUSIONS: When compared with patients in the early group, recent cohort patients received significantly fewer blood transfusions. The authors attribute this observation to changes in surgical technique rather than a significant alteration in transfusion triggers over the studied time period.

Critical care issues in patients after liver transplantation.

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.

Critical care of the end-stage liver disease patient awaiting liver transplantation.

Patients with end-stage liver disease awaiting liver transplantation frequently require intensive care admission and management due to either complications of liver failure or to intercurrent illness, particularly infection. Mortality in such patients is high and the development of an illness necessitating intensive care unit management can influence transplant candidacy. Specialized support frequently requires hemodynamic support, mechanical ventilation, and renal support. In this review, areas of management of particular importance to patients with end-stage liver disease in the intensive care unit are discussed. These areas are hepatic encephalopathy, infectious diseases, cardiovascular support, mechanical ventilation, renal support and combined transplantation, and decisions regarding delisting. Current knowledge specific to these patients, when available, is discussed, current practice is described, and areas of uncertainty in the evidence are discussed.

The Success of a Simulation-Based Transesophageal Echocardiography Course for Liver Transplant Anesthesiologists.

INTRODUCTION: Transesophageal echocardiography (TEE) is increasingly used for intraoperative management during orthotopic liver transplantation. Proficient TEE use requires skill and knowledge to accurately assess the hemodynamic status and guide clinical management. Currently there are no TEE educational tracks specifically focused on perioperative liver transplant management and barriers to obtaining basic certification exist. METHODS: A 4-hour simulation-based learning (SBL) course was provided to improve liver transplant anesthesiologist TEE knowledge and skill. Learners received training and education using a TEE simulator in small groups focusing on basic image acquisition, relevant anatomy, hemodynamic calculations, and pathology germane to the liver transplant period. Knowledge assessment and survey responses were assessed at the beginning and completion of the course. Learners completed TEE examinations with simulated pathology during high-fidelity simulations following the course. RESULTS: Seventeen anesthesiologists completed the course. The median baseline knowledge assessment score was 55.0% (37-70). The median postcourse knowledge assessment score improved to 95.0% (94-100) (P < .001). All anesthesiologists were able to identify TEE pathology during high-fidelity simulation. Survey responses yielded significant median score improvement in all areas assessed using a 5-point Likert scale. CONCLUSIONS: A small group, simulation TEE course delivered over 4 hours can increase knowledge and skill in TEE use for liver transplant anesthesiologists.

When Is a Critically Ill Cirrhotic Patient Too Sick to Transplant? Development of Consensus Criteria by a Multidisciplinary Panel of 35 International Experts.

BACKGROUND: Critically ill cirrhotic patients are increasingly transplanted, but there is no consensus about futile liver transplantation (LT). Therefore, the decision to delay or deny LT is often extensively debated. These debates arise from different opinions of futility among transplant team members. This study aims to achieve a multinational and multidisciplinary consensus on the definition of futility in LT and to develop well-articulated criteria for not proceeding with LT due to futility. METHODS: Thirty-five international experts from anesthesiology/intensive care, hepatology, and transplant surgery were surveyed using the Delphi method. More than 70% of similar answers to a question were necessary to define agreement. RESULTS: The panel recommended patient and graft survival at 1 year after LT to define futility. Severe frailty and persistent fever or <72 hours of appropriate antimicrobial therapy in case of ongoing sepsis were considered reasons to delay LT. A simple assessment of the number of organs failing was considered the most appropriate way to decide whether LT should be delayed or denied, with respiratory, circulatory and metabolic failures having the most influence in this decision. The thresholds of severity of organ failures contraindicating LT for which a consensus was achieved were a Pao2/FiO2 ratio<150 mm Hg, a norepinephrine dose >1 µg/kg per minute and a serum lactate level >9 mmol/L. CONCLUSIONS: Our expert panel provides a consensus on the definition of futile LT and on specific criteria for postponing or denying LT. A framework that may facilitate the decision if a patient is too sick for transplant is presented.

Cardiac risk evaluation for abdominal transplantation.

PURPOSE OF REVIEW: Cardiovascular disease has emerged as a leading cause of perioperative morbidity and mortality in renal and liver transplant patients. There is no consensus on how to diagnose cardiac disease in transplant patients. Further, there is significant disagreement in the literature regarding the use of routine screening methods to detect disease. This review will explore published observations on cardiac complications in renal and liver transplant patients to try and determine why investigators hold such divergent opinions. RECENT FINDINGS: The prevalence of cardiac disease is greater in renal and liver transplant patients than in the general public. Complications of cardiac disease play a large role in early mortality and graft loss in the postoperative period. While the presence of risk factors seems to predict coronary disease in renal disease, these factors do not perform as well in liver disease. Noninvasive stress testing for coronary artery disease seems to have low sensitivity in both transplant populations. However, the measurement of cardiac troponin seems to be of some value in predicting early mortality. SUMMARY: Physicians have not identified an effective yet cost-effective way to screen transplant patients for cardiac disease. Therefore, the first step in creating widely accepted protocols demand that physicians decide what predictive power that screening tests should have in this unique population.

Influence of Intraoperative Transesophageal Echocardiography and Pulmonary Artery Catheter Monitoring on Outcomes in Liver Transplantation.

Anesthetic management of orthotopic liver transplantation (OLT) can be challenging. Management involves responding to sudden hemodynamic shifts, addressing instability, and performing ongoing volume assessment. To best prepare for these perturbations, various monitors are used intraoperatively. We sought to explore the impact of transesophageal echocardiography (TEE) and pulmonary artery catheter (PAC) use on outcomes of patients undergoing OLT. METHODS: We retrospectively reviewed records of patients who underwent OLT at a single institution and included all who were monitored intraoperatively with TEE alone, PAC alone, or both methods concurrently (TEE + PAC). We determined whether these groups had differences in length of hospitalization (primary outcome), 30-day mortality rate, and other outcomes. RESULTS: Three hundred eighteen liver transplant operations were included in the study. Patients in the TEE + PAC group had the shortest median length of hospitalization (TEE + PAC, 8.6 days; TEE, 10.3; PAC, 9.1; P = 0.04). The TEE + PAC group also had the lowest 30-day mortality rate (TEE + PAC, n = 1 [1.3%]; TEE, n = 5 [12.8%]; PAC, n = 7 [3.5%]; P = 0.009). However, the TEE + PAC group also had the highest rate of a new postoperative need for dialysis (TEE + PAC, n = 8 [10.3%]; TEE, n = 2 [5.1%]; PAC, n = 1 [0.5%]; P < 0.001). CONCLUSIONS: Compared with either TEE alone or PAC alone, intraoperative monitoring with TEE + PAC during OLT was associated with the shortest length of hospitalization and lowest 30-day mortality rate. Transplant anesthesiologists should be aware of the potential benefit on patient mortality and hospital length of stay with concurrent intraoperative TEE + PAC monitoring and the increased need for new postoperative dialysis.

Association of Perioperative Variables and the Acute Respiratory Distress Syndrome in Liver Transplant Recipients.

BACKGROUND: The assessment of perioperative risk factors for the development of acute respiratory distress syndrome (ARDS) has been described in various surgical populations. However, there are only limited data among patients undergoing liver transplantation (LT), particularly regarding the influence of intraoperative ventilation parameters. We sought to identify the perioperative risk factors associated with the development of ARDS in LT recipients. METHODS: This is a single-center, retrospective cohort study of adult patients who underwent LT at a tertiary academic medical center between January 1, 2006, and January 31, 2016. Postoperative ARDS was identified using the Berlin definition. Multivariable logistic regression analysis was used to identify perioperative risk factors for ARDS. RESULTS: Of 817 eligible patients who underwent an LT during the study period, 20 (2.45%) developed postoperative ARDS. In the preoperative model, ongoing dialysis (odds ratio, 6.41; P < 0.01) was identified as an independent risk factor of ARDS post-LT. A higher mean peak inspiratory pressure per increase of 1 cm H2O (odds ratio, 1.31; P < 0.01) was the only independent risk factor in the intraoperative model. Patients who developed ARDS postoperatively had significantly greater intensive care unit and hospital stay compared to non-ARDS patients (P < 0.001). There were no significant differences in the 30-day (P = 0.16) and 1-year (P = 0.51) mortality between the groups. CONCLUSIONS: Dialysis at the time of transplant and elevated intraoperative mean peak inspiratory pressure were associated with the development of ARDS. ARDS post LT was associated with increased intensive care unit and hospital length of stay, but not increased mortality.

Outcomes of Liver Transplantation in Treated Portopulmonary Hypertension Patients With a Mean Pulmonary Arterial Pressure ≥35 mm Hg.

Portopulmonary hypertension (POPH), pulmonary arterial hypertension (PAH) that develops in the setting of portal hypertension, affects 5%-6% of patients with liver disease and is associated with significant morbidity and mortality. A mean pulmonary arterial pressure (mPAP) threshold of 35 mm Hg is used to stratify perioperative risk and liver transplant eligibility in treated POPH patients but does not take into account the specific factors that contribute to the pressure elevation. METHODS: In this case series, we describe the characteristics and posttransplant outcomes of patients with treated POPH and an mPAP ≥35 mm Hg and pulmonary vascular resistance (PVR) <250 dynes-s-cm-5 at or just before liver transplantation (LT). We also describe the effect of PAH therapy on pulmonary hemodynamics in patients with POPH. RESULTS: Sixteen patients were included. All patients were on PAH therapy at the time of LT. PAH therapy resulted in a decrease of mPAP (median 18.4%; interquartile range [IQR] 8.9%-27.0%) with a reduction in PVR (median 50.5%; IQR, 45.4%-70.7%), and an increase in both cardiac output (CO) (median 28.1%; IQR 5.7%-63.8%) and PAWP (median 50.0%; IQR 16.7%-108.3%) before LT. One year posttransplant survival was 69% (11/16); however, only 1 death was attributed to POPH. At 1-year posttransplant, 63.6% (7/11) of patients were weaned off all PAH therapy with clinical and echocardiographic resolution of POPH. CONCLUSIONS: In treated POPH patients with an mPAP ≥35 mm Hg and PVR < 250 dynes-s-cm-5 before LT, 1-year posttransplant survival was 69% and the majority of patients were able to discontinue PAH therapy.

APACHE III outcome prediction in patients admitted to the intensive care unit after liver transplantation: a retrospective cohort study.

BACKGROUND: The Acute Physiology and Chronic Health Evaluation (APACHE) III prognostic system has not been previously validated in patients admitted to the intensive care unit (ICU) after orthotopic liver transplantation (OLT). We hypothesized that APACHE III would perform satisfactorily in patients after OLT METHODS: A retrospective cohort study was performed. Patients admitted to the ICU after OLT between July 1996 and May 2008 were identified. Data were abstracted from the institutional APACHE III and liver transplantation databases and individual patient medical records. Standardized mortality ratios (with 95% confidence intervals) were calculated by dividing the observed mortality rates by the rates predicted by APACHE III. The area under the receiver operating characteristic curve (AUC) and the Hosmer-Lemeshow C statistic were used to assess, respectively, discrimination and calibration of APACHE III. RESULTS: APACHE III data were available for 918 admissions after OLT. Mean (standard deviation [SD]) APACHE III (APIII) and Acute Physiology (APS) scores on the day of transplant were 60.5 (25.8) and 50.8 (23.6), respectively. Mean (SD) predicted ICU and hospital mortality rates were 7.3% (15.4) and 10.6% (18.9), respectively. The observed ICU and hospital mortality rates were 1.1% and 3.4%, respectively. The standardized ICU and hospital mortality ratios with their 95% C.I. were 0.15 (0.07 to 0.27) and 0.32 (0.22 to 0.45), respectively. There were statistically significant differences in APS, APIII, predicted ICU and predicted hospital mortality between survivors and non-survivors. In predicting mortality, the AUC of APACHE III prediction of hospital death was 0.65 (95% CI, 0.62 to 0.68). The Hosmer-Lemeshow C statistic was 5.288 with a p value of 0.871 (10 degrees of freedom). CONCLUSION: APACHE III discriminates poorly between survivors and non-survivors of patients admitted to the ICU after OLT. Though APACHE III has been shown to be valid in heterogenous populations and in certain groups of patients with specific diagnoses, it should be used with caution - if used at all - in recipients of liver transplantation.

Acute Benefits After Liposomal Bupivacaine Abdominal Wall Blockade for Living Liver Donation: A Retrospective Review.

OBJECTIVE: To investigate whether the addition of liposomal bupivacaine abdominal wall blocks to a multimodal analgesic regimen improves postoperative numeric rating scale pain scores and reduces opioid consumption in patients undergoing living liver donation. PATIENTS AND METHODS: We conducted a single-center, retrospective review of patients who underwent living liver donation from January 1, 2011, through February 19, 2016, and received multimodal analgesia with (block group) or without (control group) abdominal wall blockade. The block solution consisted of liposomal bupivacaine (266 mg) mixed with 30 mL of 0.25% bupivacaine. Both groups received intrathecal hydromorphone. Main outcome measures were pain scores, opioid requirements, time to full diet, and bowel activity. RESULTS: Postoperative day 0 pain scores were significantly better in the block group (n=29) than in the control group (n=48) (2.4 vs 3.5; P=.002) but were not significantly different on subsequent days. Opioid requirements were significantly decreased for the block group in the postanesthesia care unit (0 vs 9 mg oral morphine equivalents; P=.002) and on postoperative day 0 (7 vs 18 mg oral morphine equivalents; P=.004). Median (interquartile range) time to full diet was 23 hours (14-30 hours) in the block group and 38 hours (24-53 hours) in the control group (P=.001); time to bowel activity was also shorter in the block group (45 hours [38-73 hours] vs 67 hours [51-77 hours]; P=.01). CONCLUSION: Abdominal wall blockade with liposomal bupivacaine after donor hepatectomy provides an effective method of postoperative pain control and decreases time to full diet and bowel activity.

Organ Donor Management: Part 1. Toward a Consensus to Guide Anesthesia Services During Donation After Brain Death.

Worldwide 715 482 patients have received a lifesaving organ transplant since 1988. During this time, there have been advances in donor management and in the perioperative care of the organ transplant recipient, resulting in marked improvements in long-term survival. Although the number of organs recovered has increased year after year, a greater demand has produced a critical organ shortage. The majority of organs are from deceased donors; however, some are not suitable for transplantation. Some of this loss is due to management of the donor. Improved donor care may increase the number of available organs and help close the existing gap in supply and demand. In order to address this concern, The Organ Donation and Transplantation Alliance, the Association of Organ Procurement Organizations, and the Transplant and Critical Care Committees of the American Society of Anesthesiologists have formulated evidence-based guidelines, which include a call for greater involvement and oversight by anesthesiologists and critical care specialists, as well as uniform reporting of data during organ procurement and recovery.

Right hepatectomy for living liver donation vs right hepatectomy for disease: intraoperative and immediate postoperative comparison.

HYPOTHESIS: Perioperative events of patients undergoing living donor (LD) right hepatectomy are similar to those of patients undergoing right hepatectomy for disease (DZ). DESIGN: Institutional review board-approved retrospective case-control study. SETTING: Eight hundred-bed tertiary care referral center. PATIENTS AND METHODS: We matched 40 patients who had LD with 40 patients who had DZ. Perioperative events (anesthesia, surgical events, transfusion, hemodynamic events, complications, and length of hospital stay) were compared using the signed rank test and exact McNemar test where appropriate. MAIN OUTCOME MEASURES: Intraoperative time, transfusion requirements, postoperative complications, and hospital length of stay. RESULTS: There was a significant difference in surgical time between the LD and DZ groups (median, 4.1 vs 3.3 hours; P = .001). There was also a significant difference in anesthesia time between the LD and DZ groups (median, 5.6 vs 4.2 hours; P<.001). The level of autologous transfusion was higher in the LD group (median, 1.3 vs 0 U in the DZ group; P<.001), and that of packed red blood cell transfusion was lower in the LD group (mean, 0 vs 0.5 U; P = .008). There was no other significant intraoperative difference. Postoperative hemoglobin levels were significantly higher in the LD group (median, 12.6 vs 11.8 g/dL; P = .03). Comparison of the number of complications in the immediate postoperative period revealed no other significant differences. CONCLUSIONS: The LD procedure took longer to perform because of the time required for hilar dissection. The difference in intraoperative transfusions is attributable to use of cell salvage and retransfusion of salvaged blood for all donors; this was not routine for DZ procedures. Perioperative outcomes were similar in all other respects. The LD procedure has similar outcomes to those of the DZ procedure.

Adapting the Surgical Apgar Score for Perioperative Outcome Prediction in Liver Transplantation: A Retrospective Study.

BACKGROUND: The surgical Apgar score (SAS) is a 10-point scale using the lowest heart rate, lowest mean arterial pressure, and estimated blood loss (EBL) during surgery to predict postoperative outcomes. The SAS has not yet been validated in liver transplantation patients, because typical blood loss usually exceeds the highest EBL category. Our primary aim was to develop a modified SAS for liver transplant (SAS-LT) by replacing the EBL parameter with volume of red cells transfused. We hypothesized that the SAS-LT would predict death or severe complication within 30 days of transplant with similar accuracy to current scoring systems. METHODS: A retrospective cohort of consecutive liver transplantations from July 2007 to November 2013 was used to develop the SAS-LT. The predictive ability of SAS-LT for early postoperative outcomes was compared with Model for End-stage Liver Disease, Sequential Organ Failure Assessment, and Acute Physiology and Chronic Health Evaluation III scores using multivariable logistic regression and receiver operating characteristic analysis. RESULTS: Of 628 transplants, death or serious perioperative morbidity occurred in 105 (16.7%). The SAS-LT (receiver operating characteristic area under the curve [AUC], 0.57) had similar predictive ability to Acute Physiology and Chronic Health Evaluation III, model for end-stage liver disease, and Sequential Organ Failure Assessment scores (0.57, 0.56, and 0.61, respectively).Seventy-nine (12.6%) patients were discharged from the ICU in 24 hours or less. These patients' SAS-LT scores were significantly higher than those with a longer stay (7.0 vs 6.2, P < 0.01). The AUC on multivariable modeling remained predictive of early ICU discharge (AUC, 0.67). CONCLUSIONS: The SAS-LT utilized simple intraoperative metrics to predict early morbidity and mortality after liver transplant with similar accuracy to other scoring systems at an earlier postoperative time point.
