Changes in three recognized liver function tests are reported following the use of propofol in 30 fit, unpremedicated women in whom propofol was used as the main anaesthetic agent. Doses of 140 to 330 mg were given, together with nitrous oxide and oxygen. All patients were undergoing minor gynaecological operations and all conformed to Grade 1 physical status of American Society of Anesthesiologists Classification. In none of these patients was there hypoxia or hypercarbia at any time during or following anaesthesia and none of the patients received any other drugs until completion of the study. No significant changes in liver enzymes (aspartate transaminase and alanine transaminase) or in serum alkaline phosphatase were detected.

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.

To investigate whether hypercapnic acidosis, induced by adding CO2 to inspired gas, would be protective effect against ventilator-induced lung injury (VILI), we ventilated 55 normal white rabbits for 6 hr or until PaO2/FIO2 <200 mmHg. Control group (n=15) was ventilated with peak inspiratory pressure (PIP) of 15 cm H2O, positive end-expiratory pressure (PEEP) of 3 cm H2O, an inspiration-to-expiration ratio of 1:2, and an inspired oxygen fraction (FIO2) of 0.40. High pressure hypercapnic group (HPHC; n=20) was ventilated with PIP of 30 cm H2O, PEEP of 0 cm H2O, and FIO2 of 0.40. Carbon dioxide was introduced into the inspiratory limb of the ventilator circuit, as necessary to maintain hypercapnia (PaCO2, 65 to 75 mmHg). High pressure normocapnic group (HPNC; n=20) was ventilated with same setting of HPHC, except normocapnia (PaCO2, 35 to 45 mmHg). Bronchoalveolar lavage fluid (BALF) lactate dehydrogenase, aspartate aminotransferase, interleukin-8 were significantly higher in high pressure ventilator group than control group (p<0.05). Wet weight to dry weight (WW/DW) and histologic scores were significantly higher in high pressure ventilator group than control group (p<0.05). However, there were no significant differences in oxygenation, BALF inflammatory markers, WW/DW and histologic scores between HPHC and HPNC groups. These findings suggest that hypercapnic acidosis at least induced by CO2 insufflation would not be protective effect against VILI in this model.
