Abstract
Keeping patients on mechanical ventilation after orthotopic liver transplantation (OLT) has been a standard anesthetic approach since the first utilization of liver transplantation. Advances in anesthetic management, surgical techniques and patient preparation, in addition to improved postoperative care and the reported advantages of early postoperative tracheal extubation of liver recipients. encouraged us to extubate most recipients at the end of the operation. The aim of the present study is to evaluate the pediatric liver recipients who were extubated immediately at the end of transplantation, in terms of respiratory complications and allograft function during their stay in the ICU. We retrospectively reviewed the records of 40 pediatric recipients who had undergone OLT at the Ege University Organ Transplantation Center between December 1997 and July 2002. Twelve out of 40 patients who had consecutively undergone OLT were extubated immediately at the end of the operation and were included this study. Mean Child Pugh scores of the patients were 9 +/- 2.3 (range 6-12) and the mean PELD score was 23.1 +/- 12.3 (range 7-41). The mean age of the patients was 8.4 +/- 5.2 (range 0.8-16.8 yr). Five of the 12 extubated patients received a cadaveric and seven a living donor liver graft. The mean ICU stay of the patients was 49.1 +/- 24.2 h (6-120 h). No patients required reintubation or mechanical ventilation in the ICU. Respiratory complications diagnosed in the 12 extubated patients were hypercapnia without hypoxemia in three, atelectasis in one and pleural effusion in two. No primary non-function or delayed graft function was detected. The aspartate transaminase (AST), alanine transaminase (ALT) and protrombin time (PT) were normalized within a week. We believe that immediate tracheal extubation in the operating room is a safe procedure for selected cadaveric and living-related liver transplant recipients and will facilitate the patients' recovery and mobilization leading to reduction in complications and a reduced ICU stay.
