Perioperative Characteristics and Outcomes of Fontan Versus Non-Fontan Patients Undergoing Combined Heart-Liver Transplantation: A Retrospective Cohort Study. J Cardiothorac Vasc Anesth 2024; 38:745-754. [PMID: 38172029 DOI: 10.1053/j.jvca.2023.11.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 11/24/2023] [Accepted: 11/29/2023] [Indexed: 01/05/2024]
Abstract
OBJECTIVES Combined heart-liver transplantation (CHLT) is becoming increasingly frequent as a maturing population of patients with Fontan-palliated congenital heart disease develop advanced liver fibrosis or cirrhosis. The authors present their experience with CHLT for congenital and noncongenital indications, and identify characteristics associated with poor outcomes that may guide intervention in high-risk patients. DESIGN This was a single-center retrospective cohort study. SETTING This study was conducted at Vanderbilt University Medical Center in Nashville, Tennessee. PARTICIPANTS The study included 16 consecutive adult recipients of CHLT at the authors' institution between April 2017 and February 2022. INTERVENTIONS Eleven patients underwent transplantation for Fontan indications, and 5 were transplanted for non-Fontan indications. MEASUREMENTS AND MAIN RESULTS Compared with non-Fontan patients, Fontan recipients had longer cardiopulmonary bypass duration (199 v 119 minutes, p =m0.002), operative times (786 v 599 minutes, p = 0.01), and larger blood product transfusions (15.4 v 6.3 L, p = 0.18). Six of 16 patients required extracorporeal membrane oxygenation (ECMO), of whom 4 were Fontan patients who subsequently died. Patients who required ECMO had lower 5-hour lactate clearance (0.0 v 3.5 mmol/L, p = 0.001), higher number of vasoactive infusions, lower pulmonary artery pulsatility indices (0.58 v 1.77, p = 0.03), and higher peak inspiratory pressures (28.0 v 18.5 mmHg, p = 0.01) after liver reperfusion. CONCLUSIONS Combined heart-liver transplantation in patients with Fontan-associated end-organ disease is particularly challenging and associated with higher recipient morbidity compared with non-Fontan-related CHLT. Early hemodynamic intervention for signs of ventricular dysfunction may improve outcomes in this growing high-risk population.

Hypothermic Oxygenated Machine Perfusion (HOPE) Prior to Liver Transplantation Mitigates Post-Reperfusion Syndrome and Perioperative Electrolyte Shifts. J Clin Med 2022; 11:jcm11247381. [PMID: 36555997 PMCID: PMC9786550 DOI: 10.3390/jcm11247381] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 12/08/2022] [Accepted: 12/09/2022] [Indexed: 12/14/2022] Open
Abstract
(1) Background: Post-reperfusion syndrome (PRS) and electrolyte shifts (ES) represent considerable challenges during liver transplantation (LT) being associated with significant morbidity. We aimed to investigate the impact of hypothermic oxygenated machine perfusion (HOPE) on PRS and ES in LT. (2) Methods: In this retrospective study, we compared intraoperative parameters of 100 LTs, with 50 HOPE preconditioned liver grafts and 50 grafts stored in static cold storage (SCS). During reperfusion phase, prospectively registered serum parameters and vasopressor administration were analyzed. (3) Results: Twelve percent of patients developed PRS in the HOPE cohort vs. 42% in the SCS group (p = 0.0013). Total vasopressor demand in the first hour after reperfusion was lower after HOPE pretreatment, with reduced usage of norepinephrine (−26%; p = 0.122) and significant reduction of epinephrine consumption (−52%; p = 0.018). Serum potassium concentration dropped by a mean of 14.1% in transplantations after HOPE, compared to a slight decrease of 1% (p < 0.001) after SCS. The overall incidence of early allograft dysfunction (EAD) was reduced by 44% in the HOPE group (p = 0.04). (4) Conclusions: Pre-transplant graft preconditioning with HOPE results in higher hemodynamic stability during reperfusion and lower incidence of PRS and EAD. HOPE has the potential to mitigate ES by preventing hyperpotassemic complications that need to be addressed in LT with HOPE-pre-treated grafts.

Abstract
Hemodynamic instability (HDI) during liver transplantation (LT) can be difficult to manage and increases postoperative morbidity and mortality. In addition to surgical causes of HDI, patient- and graft-related factors are also important. Nitric oxide-mediated vasodilatation is a common denominator associated with end-stage liver disease related to HDI. Despite intense investigation, optimal management strategies remain elusive. In this consensus article, experts from the International Liver Transplantation Society, the Liver Intensive Care Group of Europe, and the Society for the Advancement of Transplant Anesthesia performed a rigorous review of the most current literature regarding the epidemiology, causes, and management of HDI during LT. Special attention has been paid to unique LT-associated conditions including the causes and management of vasoplegic syndrome, cardiomyopathies, LT-related arrhythmias, right and left ventricular dysfunction, and the specifics of medical and fluid management in end-stage liver disease as well as problems specifically related to portal circulation. When possible, management recommendations are made.

Abstract
BACKGROUND During orthotopic liver transplantation (OLT), liver graft ischemia-reperfusion injury (IRI) triggers a cytokine-mediated systemic inflammatory response, which impairs graft function and disrupts distal organ homeostasis. The objective of this prospective, observational trial was to assess the effects of IRI on lung and chest wall mechanics in the intraoperative period of patients undergoing OLT. METHODS In 26 patients undergoing OLT, we measured elastance of the respiratory system (ERS), partitioned into lung (EL) and chest wall (ECW), hemodynamics, and fluid and blood product intake before laparotomy (T1), after portal/caval surgical clamp (T2), and immediately (T3) and, at 90 and 180 minutes post-reperfusion (T4 and T5, respectively). Interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), IL-1β and tumor necrosis factor-α plasma concentrations were assessed at T1, T4 and T5. RESULTS EL significantly decreased from T1 to T2 (13.5±4.4 vs 9.7±4.8 cmH2O/L, P<0.05), remained stable at T3, while at T4 (12.3±4.4 cmH2O/L, P<0.05) was well above levels recorded at T2, reaching its highest value at T5 (15±3.9 cmH2O/L, P<0.05). Variations in ERS, EL, driving pressure (∆P) and trans-pulmonary pressure (∆PL) significantly correlated with changes in IL-6 and MCP-1 plasma concentrations, but not with changes in wedge pressure, fluid amounts, and red blood cells and platelets administered. No correlation was found between changes in cytokine concentrations and ECW. CONCLUSIONS We found that EL, ECW, ∆P and ∆PL underwent significant variations during the OLT procedure. Further, we documented a significant association between the respiratory mechanics changes and the inflammatory response following liver graft reperfusion.

Abstract
This review aims at evaluating the existing evidence regarding post reperfusion syndrome, providing a description of the pathophysiologic mechanisms involved and possible management and preventive strategies. A PubMed search was conducted using the MeSH database, “Reperfusion” AND “liver transplantation” were the combined MeSH headings; EMBASE and the Cochrane library were also searched using the same terms. 52 relevant studies and one ongoing trial were found. The concept of post reperfusion syndrome has evolved through years to a multisystemic disorder. The implications of the main organ, recipient and procedure related factors in the genesis of this complex syndrome are discussed in the text as the novel pharmacologic and technical approaches to reduce its incidence. However the available evidence about risk factors, physiopathology and preventive measures is still confusing, the presence of two main definitions and the numerosity of possible confounding factors greatly complicates the interpretation of the studies.

Abstract
Portopulmonary hypertension (PoPH) is an often neglected form of pulmonary hypertension where pulmonary hypertension occurs in the presence of portal hypertension. PoPH is important to diagnose and treat as it may improve the patient's quality of life and improve the outcome after liver transplantation. In this review, we discuss the clinical aspects of PoPH including its pathophysiology, diagnosis, treatment, and prognosis.

Abstract
Background Acute kidney injury (AKI) is a common complication after liver transplantation (LT) and associated with a high mortality. The renal resistive index (RI) is used to assess early renal function impairment in critical care patients. However, limited data are available concerning changes of renal RI and the development of AKI early after reperfusion. We approached to investigate the changes of renal RI and AKI after reperfusion in a rat liver transplantation model. Methods Rats were randomly divided into sham group or LT group. Ten rats in each group were used for the hemodynamic study and twenty for Doppler measurements during the procedure. Ten rats were sacrificed 30 min or 2 h after the reperfusion. We harvested kidneys, serum and urine for further analysis of the renal function. Results The intrarenal RI increased significantly in the anhepatic stage and decreased significantly after the reperfusion in the LT group compared with sham group (P < 0.05). AKI was seen after the reperfusion in the LT group. No correlation was noted between the RI and renal function parameters 30 min after reperfusion. Conclusions The intrarenal RI increased significantly during the anhepatic stage, and decreased significantly early after the reperfusion. Intrarenal RI was unable to assess renal function in a rat liver transplantation model.

Abstract
In the United Kingdom, liver transplantation using donation after circulatory determination of death (DCDD) organs has increased steadily over the last few years and now accounts for 20% of UK transplant activity. The procurement of DCDD livers is actively promoted as a means of increasing the donor pool and bridging the evolving disparity between the wait-list length and the number of transplants performed. The objective of this retrospective study of a cohort of patients who were matched for age, liver disease etiology, and Model for End-Stage Liver Disease score was to determine whether differences in perioperative costs and resource utilization are associated with the use of such organs. Our results showed an increased prevalence of reperfusion syndrome in the DCDD cohort (P < 0.001), a prolonged heparin effect (P = 0.01), a greater incidence of hyperfibrinolysis (P = 0.002), longer periods of postoperative ventilator use (P = 0.03) and vasopressor support (P = 0.002), and a prolonged length of stay in the intensive therapy unit (ITU; P = 0.02). The peak posttransplant aspartate aminotransferase level was higher in the DCDD group (P = 0.007), and there was significantly more graft failure at 12 months (P = 0.03). In conclusion, we have demonstrated different perioperative and early postoperative courses for DCDD and donation after brain death (DBD) liver transplants. The overall quality of DCDD grafts is poorer; as a result, the length of the ITU stay and the need for multiorgan support are increased, and this has significant financial and resource implications. We believe that these implications require a careful real-life consideration of benefits. It is essential for DCDD not to be seen as a like-for-like alternative to DBD and for every effort to be continued to be made to increase the number of donations from brain-dead patients as a first resort.

Abstract
Donation after cardiac death (DCD) liver transplantation is associated with an increased frequency of hepato-biliary complications. The implications for renal function have not been explored previously. The aims of this single-center study of 88 consecutive DCD liver transplant recipients were (1) to compare renal outcomes with propensity-risk-matched donation after brain death (DBD) patients and (2) in the DCD patients specifically to examine the risk factors for acute kidney injury (AKI; peak creatinine ≥2 times baseline) and chronic kidney disease (CKD; eGFR <60 mL/min/1.73 m(2) ). During the immediate postoperative period DCD liver transplantation was associated with an increased incidence of AKI (DCD, 53.4%; DBD 31.8%, p = 0.004). In DCD patients AKI was a risk factor for CKD (p = 0.035) and mortality (p = 0.017). The cumulative incidence of CKD by 3 years post-transplant was 53.7% and 42.1% for DCD and DBD patients, respectively (p = 0.774). Importantly, increasing peak perioperative aspartate aminotransferase, a surrogate marker of hepatic ischemia reperfusion injury, was the only consistent predictor of renal dysfunction after DCD transplantation (AKI, p < 0.001; CKD, p = 0.032). In conclusion, DCD liver transplantation is associated with an increased frequency of AKI. The findings suggest that hepatic ischemia reperfusion injury may play a critical role in the pathogenesis of post-transplant renal dysfunction.

Abstract
The experimental investigation was performed to study the effects of methylene blue (MB) on hemodynamic, biochemical, and tissue changes among rabbits undergoing liver ischemia and reperfusion (IR). Twenty-four rabbits were randomized into 5 groups: 1, SHAM, control; 2, MB infusion bolus (3 mg/kg); 3, IR, hepatic ischemia for 60 minutes followed by 120 minutes of reperfusion; 4, MB-R, undergoing ischemia that had received an MB bolus infusion (3 mg/kg) prior to reperfusion; 5, R-MB, undergoing ischemia and MB bolus infusion after hemodynamic instability caused by reperfusion. The analysis included continuous recording of vital signs. Blood samples were collected at 0, 60, and 180 minutes of IR to determine blood gases as well as biochemical markers of liver function, nitric oxide, lipid peroxidation, and neutrophil activity. At the end of each experiment, liver tissue samples were collected for histological evaluation of parenchymae markers. Statistical analysis used two-way analysis of variance (ANOVA) tests with significance set at P<.05. Vital signs significantly improved with MB infusion, irrespective of whether it was applied before or after reperfusion. Blood gas data revealed different patterns among the SHAM, MB, IR, MB-R, and R-MB groups, without statistical significance, except for favorable lactate results in the R-MB group (P<.01), which displayed greater survival. Biochemical tests did not show significant differences among the groups, whereas histological analysis revealed favorable appearances for the MB-R and R-MB groups. The MB effect lasted long after reperfusion, suggesting that improvement in the hemodynamic parameters was not based on liver integrity, but rather was possibly related to endothelial function.

Abstract
BACKGROUND Marked hemodynamic alteration, commonly referred to as postreperfusion syndrome (PRS), often occurs after revascularization of the donor organ during orthotopic liver transplantation (OLT) and is associated with poor outcomes. This study aimed to investigate the incidence, predictive factors and clinical outcomes of PRS in Chinese patients following OLT at a liver transplantation center in China. METHODS Over a 5-year period, 330 consecutive patients who had undergone OLT for hepatocellular carcinoma or cirrhosis were included in this retrospective study. PRS was defined as a >30% decrease in the mean arterial pressure compared with that before revascularization for more than 1 minute during the first 5 minutes of graft reperfusion. The patients were divided into 2 groups according to the development of PRS: group 1 (patients with PRS, n=56) and group 2 (patients without PRS, n=274). The demographic characteristics, operative and postoperative courses, and outcomes of the patients were analyzed using SPSS version 18.0. RESULTS Multivariate regression analysis showed that left ventricular diastolic dysfunction determined by echocardiography and prolonged cold ischemia time were the independent risk factors for PRS. More patients in group 1 showed postoperative renal dysfunction than those in group 2 (19.23% vs 8.4%). Moreover, patients in group 1 also had higher intraoperative (7.14% vs 0%) and postoperative mortalities (26.92% vs 12.04%). CONCLUSION Left ventricular diastolic dysfunction and prolonged cold ischemia time contribute to a high incidence of PRS, which is associated with adverse outcomes in Chinese patients following OLT.

Abstract
BACKGROUND Orthotopic liver transplantation (OLT) stresses the cardiovascular system, and cardiac complications after OLT are common. METHODS Hundred ninety-seven patients (>or=40 years) who had OLT from 2002 to 2007 were reviewed to identify predictors of cardiac complications within 6 months after transplantation. RESULTS Median age was 56 years (40-75 years); 69% men. Reasons for OLT were hepatitis C virus (HCV) 45.5%, alcohol 22%, hepatocellular carcinoma (HCC) 8%, primary biliary cirrhosis 10%, and others 14.5%. Eighty-two patients suffered one or more cardiac complications within 6 months after OLT (pulmonary edema=61 [overt heart failure=7], arrhythmia=13, pulmonary hypertension=7, pericardial effusion=2, and right atrial thrombus=1). Cardiac causes were the leading cause of death (n=5; 23.8% of all mortality). By multivariate analysis, after adjusting for age and sex, independent predictors were adverse intraoperative cardiovascular events (adjusted odds ratio; 95% confidence interval: 5.89, 1.82-19.14), history of cardiac disease (2.42, 0.89-6.6), and i-MELD (integrated model for end-stage liver disease) score (1.08, 1.02-1.14), whereas adverse intraoperative cardiovascular events (5.73, 1.96-16.78) and i-MELD (1.07, 1.01-1.13) predicted pulmonary edema. None of the following variables predicted complications: age, sex, OLT indication, body mass index, blood pressure, alcohol and smoking history, pre-OLT investigations (chest X-ray, electrocardiogram, echocardiography, coronary angiography, pulmonary arterial pressure, and 2-methoxy isobutyl isonitrile scan), immunosuppressive treatment, or intraoperative variables (transfusion amount, cadaveric vs. living graft or cold ischemia and rewarming times). CONCLUSIONS Cardiac complications after OLT are common and were the leading cause of death after surgery. Adverse intraoperative cardiovascular events, previous cardiac disease, and advanced liver disease as quantified by i-MELD score predicted postoperative cardiac complications.

Abstract
INTRODUCTION The current donor selection criteria have changed from the past years. Primary nonfunction is a serious complication after liver transplantation, but initial poor function (IPF), which occurs from 2% to 23%, also has an increased morbidity and mortality. We analyzed prognostic factors associated with IPF. MATERIALS AND METHOD This retrospective study of 551 liver transplants performed from January 2000 to December 2005 excluded retransplantations and transplants by classic surgery. The study cohort was attentified according to the presence or the absence of IPF. The variables included were (1) donor age, gender, cause of death, length of stay in Critical Care Medicine, noradrenaline use, sodium levels, and cardiorespiratory arrest, (2) from the standpoint of surgery: we included ischemia time (IT), intervention time, units of packet red cells (PRC), volume of blood autotransfusion (VBA), postreperfusion syndrome (PRS), and vasoactive drugs within the surgery procedure (VAD); (3) from the recipient's: view we examined age, gender, etiology, functional state, and covermittant pathology; (4) During the postoperative period we noted the presence of postoperative hemorrhage. Statistical analysis used chi-square test, Student t test, multiple logistic regression with significance set at P < .05. RESULTS Differences were found in IT (P = .001), VBA (P = .001), PRS (P = .012), VAD (P = .03), fulminant hepatic failure as the cause the transplantation (P = .002), and chronic obstructive pulmonary disease (P = .007). A regression model retained the following variables: IT, VBA, PRS, fulminant hepatic failure, and chronic obstructive pulmonary disease. CONCLUSIONS The prognostic factors for IPF need to be modified together with donor selection criteria in liver transplantation.

Abstract
The purpose of this article is to evaluate the use of perioperative antithrombotics in patients undergoing surgical revascularization of the coronary vessels. Although there is a general agreement about the use of anticoagulation during off-pump coronary revascularization (OPCAB), the degree of the required anticoagulation varies from one center to another. The review is divided into four major sections. The first section describes the pathophysiology of the coagulation system in cardiac surgery with and without the use of cardiopulmonary bypass. In this section, we also discuss the interactions between the coagulation system and the inflammatory response to cardiac surgery. The second section examines the role of prophylactic antithrombosis in patients referred to surgical revascularization, and their role in bleeding complications associated with surgery. Heparinization and neutralizing its anticoagulative effects during coronary surgery are discussed in the third section. The fourth section examines the evidence that the inflammatory response contributes to adverse peri-operative events, in particular organ dysfunction, and potential therapeutic strategies to control this response. The review concludes with a summary of potential future research directions and key deficiencies in our knowledge regarding the use of anticoagulants in cardiac surgery.

Abstract
Living donor liver transplantation has increasingly become an alternative to cadaveric donor liver transplants for select adult patients. Because these cases can be performed electively, living donor recipients may have better compensated liver disease at the time of surgery than cadaver donor recipients. However, it is unknown if this difference would have a significant effect on their intraoperative course. Therefore, we compared the intraoperative fluid management of patients receiving liver grafts from either living or cadaveric donors (n = 25, each group). Patient groups did not differ in demographics or baseline laboratory values. The duration of anesthesia and anhepatic phases were significantly longer in living donor cases (651 +/- 80 minutes vs 409 +/- 20 and 55 +/- 14 vs 45 +/- 6, P < .05). Adjusted for anesthesia time and patient weight, fluid administration (crystalloid and albumin) was not different between the two groups. Intraoperative transfusion requirements were also not significantly different in recipients from living donors versus cadaveric donors with regard to red blood cells, fresh frozen plasma, platelets, and cryoprecipitate. However, arterial oxygenation was better preserved in recipients from living donors. The PaO2/FiO2 (P/F) ratio at the end of the procedure was significantly better in patients receiving livers from living rather than from cadaveric donors (P/F ratio 335 +/- 114 mm Hg vs 271 +/- 174, P < .05). Our results indicate that while intraoperative fluid and transfusion requirements are similar, the impact of transplantation on pulmonary gas exchange is more pronounced in patients receiving organs from cadaveric donors. This difference may arise from longer cold ischemia times present in the cadaveric donor group.

Abstract
Hemodynamic changes and elevation of intracellular calcium following reperfusion in human liver transplantation occur rapidly and do not match the time course of cytokine expression, therefore, we postulate involvement of other, pre-formed substances, such as complement. We studied 40 adult patients undergoing liver transplantation. Blood was drawn for estimation of C3, C4, C3 degradation product, membrane attack complex, and CH100 levels and elastase (a marker of neutrophil activation) at induction of anesthesia, 5 minutes before reperfusion, 5 minutes and 60 minutes after reperfusion. Cardiac output was measured by thermodilution and systemic vascular resistance was calculated at these same time points. There was a significant rise in C5b-9 membrane attack complex (P =.0012) with a corresponding fall in C3 (P =.0013) and C4 (P =.0002) levels and a rise in C3 degradation product levels (P =.0006). There was no significant change in CH100. These changes very closely followed the hemodynamic changes of a significant fall in systemic vascular resistance index (P =.0024) and increase in cardiac index (P =.0005). Elastase rose from 356 +/- 53 to 557 +/- 40 microg/L (P <.0001). There is complement activation and neutrophil activation at reperfusion in liver transplantation. Dilution alone cannot explain the fall in C3 and C4 levels as there is a corresponding increase in membrane attack complex and C3 degradation product levels with time. As both C3 and C4 are consumed, the classical pathway must be active, though alternative and lectin activated pathways may also be involved. These findings may, at least in part, explain the hemodynamic changes typically seen at reperfusion in liver transplantation.

Abstract
We investigated the clinical significance of time of onset, duration, and type of pulmonary edema after orthotopic liver transplantation by retrospectively reviewing 93 consecutive recipients. Pulmonary edema was diagnosed by means of radiographic criteria and Pao(2)/Fio(2) ratio <300. Type was identified by pulmonary artery wedge pressure (hydrostatic, >18 mm Hg; permeability, < or =18 mm Hg). Of 91 evaluable patients, 44 (48%) had no pulmonary edema, 23 (25%) had immediate pulmonary edema resolving within 24 hours, 8 (9%) had late pulmonary edema (developing de novo in the first 16 to 24 hours), and 16 (18%) had persistent pulmonary edema (developing immediately and persisting for at least 16 hours). At 16 to 24 hours, mean arterial pressure was lower with persistent permeability-type edema than without pulmonary edema (75 versus 87 mm Hg, P <.01). Patients with persistent permeability-type edema had higher mean pulmonary arterial pressure (23 versus 16 mm Hg, P <.01) and higher pulmonary vascular resistance (103 versus 53 dyn. second. m(-5), P <.05), consistent with a resistance-dependent mechanism. Patients with persistent hydrostatic-type edema did not differ from those without edema in mean arterial pressure (84 versus 87 mm Hg, P >.05) or pulmonary vascular resistance (67 versus 53 dyn. second. m(-5), P >.05), but had increased mean pulmonary arterial pressure (27 versus 16, P <.01), suggesting a flow volume-dependent mechanism. Duration of mechanical ventilation, intensive care, and hospital stay were prolonged in patients with late or persistent permeability-type edema but not in patients with immediate pulmonary edema of any type. In conclusion, immediate pulmonary edema resolving within 24 hours after liver transplantation had little clinical consequence; persistent permeability-type pulmonary edema portended a worse outcome.

Abstract
OBJECTIVE The postreperfusion syndrome (PRS) occurrence was evaluated in patients undergoing liver transplantation in our institution to determine the relationship between PRS and associated variables. METHODS Of the 185 consecutive liver transplants, pediatric patients, patients with uncompleted data or retransplantations were excluded. The remaining 145 adult patients having 77 cadaveric and 68 living donor right lobe liver transplantations were studied. PRS was defined as a decrease in mean arterial pressure >30% below the baseline value. Logistic regression was used for statistical analyses. A P value <.05 was considered as significant. RESULTS Total rate of PRS occurrence was 48.9% (71 patients) for the 145 patients. Logistic regression analyses revealed a significant relationship between the PRS and four of the variables: shorter duration of the anhepatic period, higher mean calcium requirement, higher mean heart rate difference from anhepatic to reperfusion period and lower central venous pressure at the dissection period during operations (P <.05). We could not demonstrate any significant effect of the operation type-surgical technique and duration of operations, blood and fresh frozen plasma volume transfused, demographic variables of the recipients, donor liver factors, other haemodynamic and metabolic variables at specific time periods (P >.05). CONCLUSIONS In conclusion, it is important that PRS does not seem to occur in a predictable manner in this study except for the increased calcium requirements during the operations in PRS experienced patients. The clinical parameters as graft ischemia time, the type of the operation, demographic variables of the recipient, hemodynamic or metabolic variables and transfusion needs during the operations seemed to have no contribution to PRS occurrence.

Abstract
UNLABELLED After graft reperfusion in orthotopic liver transplantation (OLT), ischemia reperfusion syndrome (IRS) is characterized by persistent hypotension with a low systemic vascular resistance. Methylene blue (MB) has been used as a vasopressor in sepsis and acute liver failure. We investigated the effect of MB on IRS during OLT. Thirty-six patients undergoing elective OLT were randomized to receive either a bolus of MB 1.5 mg/kg before graft reperfusion, or normal saline (placebo). We recorded hemodynamic variables, postoperative liver function tests, and time to hospital discharge. Blood samples were analyzed for arterial lactate concentration, cyclic 3',5'-monophosphate, and plasma nitrite/nitrate concentrations. The MB group had higher mean arterial pressure (P = 0.035), higher cardiac index (P = 0.04), and less epinephrine requirement (P = 0.02). There was no difference in systemic vascular resistance or central venous pressure. Serum lactate levels were lower at 1 h after reperfusion in MB patients, suggesting better tissue perfusion (P = 0.03). In the presence of MB, there was a reduction in cyclic 3',5'-monophosphate (P < 0.001), but not plasma nitrites. Postoperative liver function tests and time to hospital discharge were the same in both groups. MB attenuated the hemodynamic changes of IRS in OLT acting via guanylate cyclase inhibition. IMPLICATIONS Methylene blue attenuates the hemodynamic changes of the ischemia reperfusion syndrome in liver transplantation, and this effect involves guanylate cyclase inhibition.

Abstract
BACKGROUND Oxidative stress and leukocyte-endothelial interactions contribute significantly to the reperfusion injury of the transplanted liver. Therefore, we investigated the effect of N-acetylcysteine (NAC) on reperfusion injury and circulating adhesion molecules during human liver transplantation. METHODS In a prospective study, 10 orthotopic liver transplantation patients were treated with high-dose NAC and 10 patients were treated with 5% glucose (placebo group) immediately before and during reperfusion of the donor liver. Parameters of hepatocellular injury, cellular oxygenation, plasma cytokines, and circulating adhesion molecules were determined at various time points during the liver transplantation. RESULTS NAC had no significant effect on the arterial lactate/pyruvate or hydroxybutyrate/acetoacetate ratio during the liver transplantation. At baseline, liver transplantation patients exhibited elevated levels of cytokines and circulating adhesion molecules compared with healthy volunteers (n=7). While no significant effect of NAC on circulating L- and P-selectin was observed, it significantly inhibited the increase in circulating ICAM-1 and VCAM-1 24 hr after reperfusion. There were no significant differences in maximal postoperative values of serum aspartate transaminase (peak AST) or alanine transaminase (peak ALT) between both groups. However, NAC significantly reduced the rise in alpha-glutathione S-transferase after reperfusion of the donor liver. CONCLUSIONS NAC attenuated the increase in alpha-glutathione S-transferase and circulating ICAM-1 and VCAM-1 after reperfusion of the donor liver, indicating possible cytoprotective effects of NAC.
