High incidence of postoperative pulmonary complications after orthotopic liver transplantation in children

Postoperative pulmonary complications were investigated in a total of 41 pediatric recipients who underwent orthotopic liver transplantation (OLT) between January, 1990 and March, 1992 at the Royal Children's Hospital, Brisbane. Atelectasis was seen in 40 cases (98%) of the 41 recipients, and occurred in the left lower lobe in 28 cases (68%), and in the right upper lobe in 25 cases (61%). Radiographic pulmonary edema occurred on 23 occasions in 18 recipients (45%). Pulmonary edema was observed just after operation in 9 cases, and in the later stage from the 3rd to 25th postoperative day in 14 cases. Five recipients experienced two episodes of pulmonary edema during their ICU stay. The duration of mechanical ventilatory support was significantly longer in the patients with pulmonary edema than in those without (9.6±3.8vs 3.9±2.2 days,P
