Experience Verification of 63 Cases of Liver Transplantation Anesthesia Management

Abstract

Background: We reviewed the intraoperative management of previous liver transplantation (LT) cases to identify an optimal anesthetic method, which may affect patient outcomes and lead to faster postoperative recovery for future recipients. Methods: This single-center retrospective study reviewed 63 patients who underwent LT, including 51 living donor LT (LDLT), seven deceased donor LT (DDLT), and five simultaneous liver-kidney transplantation patients. We examined the patients’ backgrounds, intraoperative management (anesthetic method, water balance, and catecholamine dosage), and postoperative courses (hospitalization period, length of intensive care unit stay, renal function). Results: All patients received general anesthesia using inhalational anesthetics, either sevoflurane or desflurane, and both drugs were administered similarly. Rocuronium was administered at its usual dose despite liver failure. All patients undergoing preoperative dialysis due to acute kidney injury were successfully withdrawn from dialysis after surgery. The albumin infusion volume was 32% of the total infusion and transfusion volume. The five-year survival rate was 88% and graft failure occurred in one case. Conclusion: The anesthetic management of LT is currently conducted empirically in our institution, and we could not identify an optimal anesthetic method. However, we drew some conclusions. First, the use of human atrial natriuretic peptide as a drug infusion and appropriate transfusion management was expected to restore renal function. Second, the infusion volume of albumin was high. Third, the usual dose of rocuronium was required because excessive bleeding may cause unstable plasma drug concentration. Our results will be useful in future multi-institutional studies or meta-analyses and further improving the outcomes of future transplant recipients.
