Abstract

Pulmonary function and gas exchange were prospectively studied in 95 patients before and 9 to 15 months following liver transplantation. Pretransplant, the most common PF abnormality was impaired efficiency of gas exchange as measured by Dss. As a group, the mean Dss was 78.0 ± 16.6 percent predicted and was found to be less than 80 percent predicted in 50 patients. As a group, patients with the most severe liver diseases clinically (Child's C classification) had the lowest mean Dss pretransplant. Posttransplant, three findings were of clinical importance: PaCO2 significantly improved posttransplantation, suggesting a resolution of pretransplant respiratory alkalosis. Expiratory airflow obstruction, measured by a change in the FEV1/FVC, was extremely uncommon posttransplant. Mean Dss improved significantly in patients with Child's C severity of liver disease. The most frequent deteriorations in Dss statistically were associated with posttransplant thoracotomy, ARDS, nonspecific pneumonitis, significant pleural effusions and hepatic retransplantation.
