Pulmonary complications following major lung resection for benign and malignant lung diseases.

OBJECTIVE To assess the incidence and to identify the possible associated risk factors for postoperative pulmonary complications after major lung resection. SUBJECTS AND METHODS One hundred and sixty-eight consecutive patients undergoing major lung resection for benign and malignant lung disease over a 3-year period were included in the study. Preoperative assessment clinical parameters, intraoperative and postoperative events were recorded. Pulmonary complications were noted according to a precise definition. The risk of complications associated with age, comorbidity, forced vital capacity (FVC), blood transfusion and extended operation was evaluated using logistic regression analysis. RESULTS The mean age of the patients was 47.1 years (range 16-80 years), 137 (77%) patients underwent lobectomy, 23 (14%) pneumonectomy, and 15 (9%) bilobectomy. Forty-six (27%) patients developed postoperative pulmonary complications and 2 (1.1%) died within 30 days following the operation. Age > or =65 years (OR 3.7, 95% CI: 1.5-8.6, p = 0.002), the presence of comorbid cardiopulmonary disease (OR 0.2, 95% CI: 0.1-0.5, p = 0.001), FVC <50% (OR 0.2, 95% CI: 0.1-0.8, p = 0.02), blood transfusion (OR 0.2, 95% CI: 0.1-0.4, p = 0.0001), and extended operation (OR 0.2, 95% CI: 0.07-0.6, p = 0.005) were the identified factors associated with the development of postoperative pulmonary complications, which necessitated an increased length of hospital stay. CONCLUSION Postoperative pulmonary complications are more likely to develop in patients with age > or =65 years with comorbid cardiopulmonary disease, FVC <50%, blood transfusion, and extended operation.
