Purpose: The early post-transplant period after liver transplantation is critical, as recipients are highly susceptible to sepsis due to their immune-compromised state. This study aimed to identify the association between preoperative procalcitonin and early post-transplant sepsis and mortality at one month after living donor liver transplantation (LDLT)., Methodology: All patients who underwent LDLT from July 2021 to December 2021 were recruited prospectively. Participants were divided into two groups based on preoperative PCT levels: elevated (>0.5 ng/ml) and low levels (<0.5 ng/ml). Serum procalcitonin (PCT) levels were measured on the day of transplant and on postoperative days 3 and 7. The relationship between preoperative PCT and post-transplant sepsis was evaluated using a Chi-square test, and receiver operating characteristic (ROC) curves were generated., Results: Sepsis occurred in 48.3% of patients, with a significant association between elevated preoperative PCT levels and early post-transplant sepsis (p=0.023). The ROC curve for preoperative PCT showed moderate predictive ability (area under curve (AUC)=0.664), while PCT levels on postoperative day 3 demonstrated better discriminatory power (AUC=0.790). PCT levels measured on day 7 also had good diagnostic accuracy, with an AUC of 0.843 and a significant difference between the sepsis and non-sepsis groups (p=0.002). The length of ICU stay was significantly longer in the sepsis group (p=0.009).  Conclusion: Elevated preoperative PCT levels can predict early post-transplant sepsis in LDLT patients. PCT monitoring may enhance risk stratification and guide perioperative management, improving post-transplant outcomes., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Timely diagnosis and management of pediatric acute liver failure (PALF) is of paramount importance to improve survival. The Indian Society of Pediatric Gastroenterology, Hepatology, and Nutrition invited national and international experts to identify and review important management and research questions. These covered the definition, age appropriate stepwise workup for the etiology, non-invasive diagnosis and management of cerebral edema, prognostic scores, criteria for listing for liver transplantation (LT) and bridging therapies in PALF. Statements and recommendations based on evidences assessed using the modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) system were developed, deliberated and critically reappraised by circulation. The final consensus recommendations along with relevant published background information are presented here. We expect that these recommendations would be followed by the pediatric and adult medical fraternity to improve the outcomes of PALF patients., (© 2024.

Introduction Endoscopic retrograde cholangiopancreatography (ERCP) is vital for diagnosing and treating biliary and pancreatic diseases, necessitating deep sedation typically achieved through total intravenous anesthesia. Propofol, with its favorable pharmacokinetic profile, is the preferred sedative, but conventional administration methods of mg/kg boluses or infusion rates pose challenges. Target-controlled infusion (TCI) systems offer a solution that ensures precise dose delivery of propofol. Despite its widespread use, the literature lacks specific guidance on the target plasma concentration (Cp) of propofol for sedation in patients undergoing ERCP. Methods A prospective interventional study was conducted at the Institute of Liver and Biliary Sciences, Delhi, India to determine the target Cp of propofol for sedation during ERCP. The study enrolled 86 American Society of Anesthesiologists (ASA) grade I and II patients aged 18-70 years. The primary objective was to establish the optimal propofol concentration for sedation as guided by a bispectral index (BIS) value of 60-70. Secondary outcomes included induction time, recovery time, total propofol consumption, and the occurrence of adverse events (if any). The Marsh pharmacokinetic model guided the TCI pump, adjusting Cp until the target sedation was achieved. Results The mean Cp of propofol to maintain the BIS value 60-70 was 2.21 ± 0.42 µg/ml. Age-wise analysis revealed variations, emphasizing the need for individualized dosing. Induction time was 4.21 ± 0.68 minutes; recovery times were seven minutes (median, IQR: 5-10 minutes) for BIS >80 and seven minutes (median, IQR: 5-10 minutes) for achieving a Modified Observer's Assessment of Alertness/Sedation score of ≥5. The mean propofol consumption was 6.24 mg/kg/hr. Side effects were minimal, with 1.16% experiencing transient hypoxia and hypotension. Conclusion The study establishes a mean target propofol concentration of 2.21 ± 0.42 µg/ml for sedation in ASA I and II patients undergoing ERCP., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Objective: The primary objective was to compare the rates of early allograft dysfunction (EAD) in patients undergoing elective adult live donor liver transplantation (ALDLT) with and without graft portal inflow modulation (GIM) for portal hyper-perfusion. The secondary objectives were to compare time to normalization of bilirubin and International Normalized Ratio (INR), day 14 ascitic output more than 1liter, small-for-size syndrome (SFSS), intensive care unit / high dependency unit and total hospital stay, and 90 day morbidity and mortality., Background: GIM can prevent EAD in ALDLT patients with portal hyper-perfusion., Methods: A single-center randomized trial with and without GIM for portal hyper-perfusion by splenic artery ligation (SAL) in ALDLT was performed. After reperfusion, patients with portal venous pressure (PVP)>15 mm Hg with a gradient (PVP - central venous pressure) of ≥ 7 mm Hg and/or portal venous flow (PVF)>250 mL/min/100 grams of liver were randomized into two groups: GIM and No GIM., Results: 75 of 209 patients satisfied the inclusion criteria, and 38 underwent GIM. Baseline PVF and PVP were comparable between the GIM and no GIM groups. SAL significantly reduced the PVF and PVP (P<0.001). There were no differences in the primary and secondary outcomes between the two groups. In the subgroup analysis, with a Graft to Recipient Weight Ratio (GRWR)≤0.8, there were no significant differences in the primary and secondary outcomes., Conclusion: SAL significantly decreased PVP and PVF, but did not decrease rates of EAD in adult LDLT., Competing Interests: Conflict of Interest: The authors declare that they have no affiliations with or involvement in any organization or entity with any financial interest in the subject matter or materials discussed in this manuscript., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objective: To compare intraoperative hemodynamic parameters, blood loss, renal function, and duration of surgery with and without temporary portocaval shunt (TPCS) in live donor liver transplantation (LT) recipients. Secondary objectives were postoperative early graft dysfunction, morbidity, mortality, total intensive care unit, and hospital stay., Background: Blood loss during recipient hepatectomy for LT remains a major concern. Routine use of TPCS during LT is not yet elucidated., Methods: This study is a single-center, open-label, randomized control trial. The sample size was calculated based on intraoperative blood loss. After exclusion, a total of 60 patients, 30 in each arm (TPCS vs no TPCS) were recruited in the trial., Results: The baseline recipient and donor characteristics were comparable between the groups. The median intraoperative blood loss ( P = 0.004) and blood product transfusions ( P < 0.05) were significantly less in the TPCS group. The TPCS group had significantly improved intraoperative hemodynamics in the anhepatic phase as compared with the no TPCS group ( P < 0.0001), requiring significantly less vasopressor support. This led to significantly better renal function as evidenced by higher intraoperative urine output in the TPCS group ( P = 0.002). Because of technical simplicity, the TPCS group had significantly fewer inferior vena cava injuries (3.3 vs 26.7%, P = 0.026) and substantially shorter hepatectomy time and total duration of surgery (529.4 ± 35.54 vs 606.83 ± 48.13 min, P < 0.0001). The time taken for normalization of lactate in the immediate postoperative period was significantly shorter in the TPCS group (median, 6 vs 13 h; P = 0.04). Although postoperative endotoxemia, major morbidity, 90-day mortality, total intensive care unit, and hospital stay were comparable between both groups, tolerance to enteral feed was earlier in the TPCS group., Conclusions: In live donor LT, TPCS is a simple and effective technique that provides superior intraoperative hemodynamics and reduces blood loss and duration of surgery., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objective: This study aimed at studying the challenges and outcomes of live-donor liver transplantation (LDLT) for pediatric acute liver failure (PALF)., Study Design: A total of 315 patients with PALF were treated over a period of 11 years. 42 underwent LT (41 LDLT and one DDLT), constituting 38% (41/110) of all pediatric transplants during this duration. The outcomes of LDLT for PALF were analyzed., Results: All the 41 children who underwent LT met the Kings College criteria (KCC). The etiology was indeterminate in 46.3% (n = 19) children. 75.6% (n = 31) were on mechanical ventilation for grade 3/4 hepatic encephalopathy. There was presence of cerebral edema on a computed tomography scan of the brain in 50% of the children. One-third of our children required hemodynamic support with vasopressors. Systemic inflammatory response syndrome and sepsis were observed in 46.3% and 41.4% of patients, respectively. Post-LDLT 1- and 5-yr patient and graft survival were 75.6% and 70.9%, respectively. The survival in children satisfying KCC but did not undergo LT was 24% (38/161). Vascular and biliary complication rates were 2.4% and 4.8%, respectively. No graft loss occurred because of acute rejection. In multivariate analysis, pre-LT culture positivity and cerebral edema, persistence of brain edema after transplantation, and resultant pulmonary complications were significantly associated with post-LT death. Thirteen (32%) children who underwent plasmapheresis prior to LT had better post-LT neurological recovery, as evidenced by early extubation., Conclusion: LDLT for PALF is lifesaving and provides a unique opportunity to time transplantation. Good long-term survival can be achieved, despite the majority of patients presenting late for transplantation. Early referral and better selection can save more lives through timely transplantation., (© 2023. Asian Pacific Association for the Study of the Liver.)

Objective: This study aimed to analyze risk factors and develop a predictive model for early allograft loss due to early graft dysfunction (EGD) in adult live-donor liver transplantation (LDLT)., Methods: Data of patients who underwent LDLT from 2011 to 2019 were reviewed for EGD, associated factors, and outcomes. A homogeneous group of 387 patients was analyzed: random cohort A (n = 274) for primary analysis and random cohort B (n = 113) for validation., Results: Of 274 recipients, 92 (33.6%) developed EGD. The risk of graft loss within 90 days was 29.3% and 7.1% in those with and without EGD, respectively ( P < 0.001). Multivariate logistic regression analysis determined donor age ( P = 0.045), estimated (e) graft weight ( P = 0.001), and the model for end-stage liver disease (MELD) score (0.001) as independent predictors of early graft loss due to EGD. Regression coefficients of these factors were employed to formulate the risk model: Predicted (P) early graft loss risk (e-GLR) score = 10 × [(donor age × 0.052) + (e-Graft weight × 1.681) + (MELD × 0.145)] - 8.606 (e-Graft weight = 0, if e-Graft weight ≥640 g and e-Graft weight = 1, and if e-Graft weight < 640 g). Internal cross-validation revealed a high predictive value (C-statistic = 0.858)., Conclusions: Our novel risk score can efficiently predict early allograft loss following graft dysfunction, which enables donor-recipient matching, evaluation, and prognostication simply and reliably in adult LDLT., Competing Interests: Disclosure: The authors declare that they have nothing to disclose., (Copyright © 2023 The Author(s).

Introduction: The current study aimed to assess the safety of early drain removal after live donor hepatectomy (LDH)., Methods: One hundred eight consecutive donors who met the inclusion criteria were randomized to early drain removal (EDR - postoperative day (POD) 3 - if serous and the drain bilirubin level was less than 3 mg/dl - "3 × 3" rule) and routine drain removal (RDR - drain output serous and less than 100 ml). The primary outcome was to compare the safety. The secondary outcome was to compare the postoperative morbidity., Results: Preoperative, intraoperative, and postoperative parameters except for the timing of drain removal were comparable. EDR was feasible in 46 out of 54 donors (85.14%) and none required re-intervention after EDR. There was significantly better pain relief with EDR (p = 0.00). Overall complications, pulmonary complications, and hospital stay were comparable on intention-to-treat analysis. However, pulmonary complications (EDR - 1.9% vs RDR - 16.3% P = 0.030), overall complications (18.8% vs 36.3%, P = 0.043), and hospital stay (8 vs 9, P = 0.014) were more in the RDR group on per treatment analysis. Bile leaks were seen in three donors (3.7% in the EDR group vs 1.9% in RDR, P = 0.558), and none of them required endo-biliary interventions. Re-exploration for intestinal obstruction was required for 3 donors in RDR (0% vs 5.7%; p = 0.079)., Conclusion: EDR by the "3 × 3" rule after LDH is safe and associated with better pain relief. On per treatment analysis, EDR was associated with significantly less hospital stay and lower pulmonary and overall complications., Clinical Trial Registry: Clinical Trials.gov - NCT04504487., (© 2023.

Hemodialysis remains the most popular modality of renal replacement therapy for end-stage renal disease patients with chronic kidney disease. Various factors such as a radial artery, cephalic vein diameter, age, hypertension, and diabetes mellitus can affect the fistula maturation. This study was carried out to know the patency rates and factors affecting fistula maturation in the Indian population. This is a prospective observational study which aimed to study the patency rate of arteriovenous (AV) fistulas. On the day of surgery, patients were shifted inside the operation theater. Under all aseptic precautions, an AV fistula was formed using the radial artery and cephalic vein. All patients were followed up for 6 months. The data were analyzed using IBM SPSS version 22. To see the change over a period of time, McNemar test for categorical data and repeated measure for continuous data followed by post hoc comparison by Bonferroni method were used. The mean age of the patients was 46.98 ± 13.33 years. The mean diameter of the cephalic vein, ulnar artery, and radial artery at the wrist was 1.733 ± 0.528, 1.700 ± 0.364, and 1.908 ± 0.420, respectively, whereas the mean diameter of the cephalic vein, ulnar artery, and radial artery at the forearm was 1.952 ± 0.488, 1.910 ± 0.421, and 2.058 ± 0.458, respectively. Immediate thrill after the surgery was present in 36/52 (69.2%) of the patients. The radial artery diameter at the wrist was significantly less in the patients with primary failure in whom immediate thrill was not present (P = 0.016). At 1-month follow-up, 30/49 (61.2%) and, at 6 months, 29/48 (60.4%) fistulas were functional. Radiocephalic AV fistulas have a reasonable success rate and minimal morbidity, and radial artery diameter is a good predictor of the outcome., (Copyright © 2024 Copyright: © 2024 Saudi Journal of Kidney Diseases and Transplantation.)

Background: Hepatic artery-related complications (HARC) after live donor liver transplantation (LDLT) is associated with high morbidity and mortality rate., Methods: Prospectively maintained data from July 2011 to September 2020 was analyzed for etiology, detection, management, and outcome of HARC., Results: Six hundred fifty-seven LDLT (adult 572/pediatrics 85) were performed during the study period. Twenty-one (3.2%) patient developed HARC; 16 (2.4%) hepatic artery thrombosis (HAT) and 5 (0.76%) non-thrombotic hepatic artery complication (NTHAC). Ninety percent (19/21) HARC were asymptomatic and detected on protocol Doppler. Median time to detection was day 4 (range - 1 to 35), which included 18 early (within 7 days) vs 3 late incidents. Only one pediatric patient had HAT. Seven patients underwent surgical revascularization, 11 had endovascular intervention and 3 with attenuated flow required only systemic anticoagulation. All NTHAC survived without any sequelae. Revascularization was successful in 81% (13/16) with HAT. Biliary complications were seen in 5 (23.8%); four were managed successfully. Overall mortality was 14.8% (3/21). The 1-year and 5-year survival were similar to those who did not develop HARC (80.9% vs 84.2%, p = 0.27 and 71.4% vs 75.19%, p = 0.36 respectively) but biliary complications were significantly higher (23.8% vs 14.2%, p = 0.03). On multivariate analysis, clockwise technique of arterial reconstruction was associated with decreased risk of HAT (1.7% vs 4.1% (p value - 0.003))., Conclusion: Technical refinement, early detection, and revascularization can achieve good outcome in patients with HARC after LDLT., (© 2023.

Introduction: The duration of perioperative antibiotic prophylaxis following live liver donor hepatectomy (LDH) is not known., Methods: This is a double-blind equivalence trial. All consecutive LDH were randomized into: group A (three doses) and group B (nine doses) of perioperative antibiotics (piperacillin + tazobactam - 4.5 g intravenous) at fixed 8 hourly intervals. Primary end point was incidence of infective complications as per CDC (Centers for Disease Control and Prevention) criteria. Secondary end points were liver function tests, total leukocyte count, international normalized ratio, hospital stay, morbidity, and cost analysis., Results: One hundred and twenty-six LDHs were enrolled. A total of 19.8% (n = 25) experienced postoperative complications, 11 (17.7%) in group A and 14 (21.9%) in group B (P = .561). Infective complications were seen in 11 donors (8.1%), five in group A and six in group B (P = .79). A total of 8.1% of donors required continuation/up-gradation of antibiotics in group A and 9.4% in group B. Return to soft diet was delayed in group B (P = .039). Median hospital stay and cost were similar., Conclusion: Three doses of perioperative antibiotic are equally effective in preventing infective complications., (© 2021 Japanese Society of Hepato-Biliary-Pancreatic Surgery.)

Objectives: This study is aimed to determine the impact of liver disease severity on the outcome of patients undergoing endourological procedures for urolithiasis, and to understand the factors that are helpful in improving the outcome., Materials and Methods: We retrospectively analyzed the records of patients with chronic liver disease who underwent endourological procedures between January 2014 and February 2020. Inpatient records and charts were assessed for age, sex, height, weight, body mass index, model for end-stage liver disease (MELD) score, Child-Turcotte-Pugh score, type of procedure and anesthesia, intensive care unit (ICU) stay, duration of hospitalization, number, size, and position of stones, and postoperative complications such as hematuria, sepsis, and secondary procedures. Data are presented as mean ± standard deviation or frequency. The chi-square test was applied to determine the exact association between categorical data and Student t-test or Mann-Whitney U test as appropriate for continuous data. Statistical significance was set at p < 0.05., Results: Hospital and ICU stay as well as administration of different blood products were significantly longer in the Child C than in the Child A and B categories ( p < 0.001). Two patients in the Child C category died, while 3 left the hospital against medical advice. The duration of ICU stay and blood products administered increased with augmenting MELD scores. The durations of hospitalization and blood product administration were significantly higher in patients with an MELD score ≥20 than in the group with MELD score <20., Conclusions: Hospital and ICU stay and blood product administration were significantly higher in Child C than in Child A and B class patients. Hospitalization duration and blood product administration were significantly higher in patients with an MELD score ≥20., Competing Interests: No conflict of interest has been declared by the author., (Copyright © 2022 The Authors.

Background: MHV reconstruction is essential to avoid anterior sector congestion in adult live donor liver transplantation (LDLT) using a modified right lobe graft., Aims: The objective of this study is to evaluate the graft and patient outcomes with single orifice outflow reconstruction technique (SORT) (RHV + neo-MHV combined reconstruction on IVC) vs. dual outflow reconstruction technique (DORT) (RHV and neo-MHV separately reconstructed on IVC) in a modified right lobe LDLT., Methods: Prospectively collected data of consecutive patients undergoing LDLT from June 2011 to August 2018 were analyzed. The patients were divided into two groups: SORT (n = 207) and DORT (n = 108). The perioperative morbidity and mortality were compared between two groups., Results: The two groups were comparable in baseline preoperative characteristics. Intraoperatively, warm ischemia time (27 vs. 45 min, p < 0.001), anhepatic phase (132 vs. 159 min, p < 0.001), and operative time (680 vs. 840 min, p < 0.001) were significantly shorter in SORT group. SORT group also had significantly lower GRWR (0.92 vs. 1.06, p < 0.001) and higher portal flow (2.4 vs. 2.7 L/min, p = 0.02). Postoperatively, SORT group had lower peak AST (177 vs. 209 IU/L, p < 0.001), ALT (163 vs. 189 IU/L, p = 0.004), creatinine levels (0.98 vs. 1.10, p = 0.01), rate of severe sepsis (13.7% vs. 22.9%, p = 0.03), major morbidity (50.7% vs. 62.6%, p = 0.03), shorter ICU (9 vs. 14 days, p < 0.001), and hospital stay (21 vs. 26 days, p = 0.03). Overall survival rates were comparable., Conclusion: A SORT leads to improved early graft function and perioperative morbidity in modified right lobe LDLT in spite of having lower GRWR and higher portal flow., (© 2020.

Ischemic and reperfusion injury (IRI) occurs during organ transplantation. IRI during liver transplantation is well studied and established; results in coagulopathy due to release of heparin-like substances and platelet trapping. During renal transplantation, similar IRI phenomenon occurs, and thromboelastography (TEG) can be used to detect and manage coagulopathy. The preoperative, immediate postreperfusion, and postoperative day 1 TEG was done on 25 cases of live-related renal transplantation. Coagulopathy was defined by deranged and abnormal TEG variables values from baseline and supported by the clinical presence of nonsurgical oozing and bleeding in the surgical field. The postreperfusion TEG values showed coagulopathic changes. About 64% of patients had R-time (RT) more than 12 min, 64% of patients showed maximum amplitude (MA) <55 mm, and 76% of patients had alpha angle <55°. The presurgical TEG clotting index (CI) was +2.45 ± 1.25, postreperfusion CI was -1.96 ± 4.54, and postoperative CI was +4.02 ± 1.35. Univariate analysis revealed that antithymocyte globulin was a significant, but etiology was closure to a significant level as protecting factor, but in multivariate analysis, both variables showed protecting factor with insignificant results. There was a weak correlation between CI with serum creatinine at all time points suggested no linear relationship between serum creatinine and corresponding CI. Hence, the results of study proves that IRI during renal transplant is associated with transient self-limiting coagulopathy, that may be early detected by TEG. CI values in postoperative 24 h apart indicating a hyper-coagulable or prothrombotic state and post-reperfusion CI values show a trend toward hypocoagulable status. No significant effect of different immunosuppression on coagulation and week correlation was found of serum creatinine level (graft function) with CI, which conclude that changes in coagulation have not affected graft function.

Background and Aims: Fluid administration during liver transplant (LT) surgery is controversial. Although adverse outcomes following positive intraoperative fluid balance have been reported, studies presenting the influence of cumulative postoperative fluid balance (CFB) on complications following LT are sparse. Patients with chronic liver disease tend to receive more fluid during and after surgery due to their unique physiological disease state. The aim of this study was to evaluate the influence of 48-hour CFB on the development of acute kidney injury (AKI) and pulmonary complications on day 4 after live donor LT., Methods: This retrospective study included 230 patients undergoing live donor LT. The effect of CFB on day 2 on AKI and pulmonary complications was analysed. Chi-square test, Fisher's exact test, samples t-test, Mann-Whitney U-test were used., Results: Bivariate analysis showed a lower graft vs recipient weight ratio (GRWR), sepsis ( P < 0.001) and a higher 48-hour CFB after surgery significantly increased the development of AKI. For pulmonary complications, higher Model for End- stage Liver Disease-Na(MELD-Na) score, higher peak arterial lactate, higher 48-hour CFB ( P = 0.016) and sepsis ( P = 0.003) were found to be statistically significant. Upon multivariate analysis, CFB at 48 hours was significantly higher in patients suffering from pulmonary complications, and GRWR and sepsis were significant for AKI. For every one litre increase in CFB on day 2, the odds of pulmonary complications increased by 37%., Conclusion: A more positive CFB on day 2 increased the development of pulmonary complications and lower GRWR and sepsis increased the development of AKI., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Indian Journal of Anaesthesia.)

Background and Aims: Coagulation dynamics after donor hepatectomy are complex. Having complete knowledge of the actual changes in the coagulation status during donor hepatectomy is important to prevent complications such as pulmonary embolism, deep vein thrombosis, and bleeding. Hence, the present study aimed to study the coagulation dynamics following open donor hepatectomy both by thromboelastography (TEG) and conventional coagulation tests (CCT)., Methods: A total of 50 prospective liver donors were included. TEG and CCT [activated partial thromboplastin time (aPTT), prothrombin time (PT), international normalised ratio (INR), fibrinogen, and platelet counts] were performed for each patient before surgery (baseline), on postoperative day (POD) 0, 1, 2, 3, 5, and 10., Results: TEG showed hypercoagulability in 28%, 38%, 30%, 46%, 42%, and 48% patients; in contrast INR showed hypocoagulability in 58%, 63%, 73%, 74%, 20%, and 0% patients on POD 0,1,2,3,5, and 10, respectively. Patients demonstrating hypercoagulability on TEG had significantly decreased reaction time ( P = 0.004), significantly increased maximum amplitude ( P < 0.001), and alpha angle value ( P < 0.001). Postoperatively, INR, PT, and aPTT values increased significantly, while platelets and fibrinogen levels decreased significantly when compared to their baseline values. There was no coagulation-related postoperative complication in any of the patients., Conclusion: Hypercoagulability after donor hepatectomy is common. TEG showed hypercoagulability and did not show any hypocoagulability as suggested by the CCT. In patients undergoing donor hepatectomy, CCT may not reflect the actual changes incoagulation status and tests such as TEG should be performed to know the correct nature of changes in coagulation following donor hepatectomy., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Indian Journal of Anaesthesia.)

Background and Aims: Postoperative pain following renal transplantation is moderate to severe. Quadratus lumborum block (QLB) is a new block that can provide effective analgesia following abdominal and retroperitoneal surgeries. This study aimed to evaluate the analgesic efficacy of QLB for postoperative analgesia in patients undergoing renal transplantation., Methods: Patients were randomised into two groups of 30 each. In group A (block group), 20 mL of 0.25% bupivacaine and group B (placebo group), 20 mLof normal saline were injected. In the postoperative room, an intravenous patient controlled analgesia (IVPCA) pump with fentanyl was started in both the group. The postoperatively recorded parameters were numerical rating scale (NRS) pain score at rest and on movement and coughing, total fentanyl consumption, sedation score, postoperative nausea vomiting, limb weakness, paralytic ileus, and any other block-related complication. Data were analysed using SPSS software version 22.0. Categorical data were analysed using the Chi-square method. Student t test or Mann-Whitney U test was applied for the continuous data. Numerical data with normal distribution were displayed as mean (standard deviation), abnormal distribution was displayed in the median (interquartile range) values, and as a percentage for categorical variables., Results: Fentanyl consumption, numerical rating score, and sedation score were significantly less in group A when compared to group B at 1, 4, 8, 12, and 24 h ( P < 0.001)., Conclusion: Type-1 QLB significantly reduces fentanyl consumption and NRS pain score at 1,4,8,12, and 24 h in the postoperative period in renal transplant recipients., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Indian Journal of Anaesthesia.)
