Implication of altered pulmonary function in pneumonectomy for tuberculous destroyed lung.

Twelve patients undergoing pneumonectomy for tuberculous destroyed lung were studied to determine the value of preoperative spirometry in the assessment of their pulmonary reserve, and prediction of their postoperative morbidity. Preoperatively, the mean functional losses (as percentage of predicted values) were 44.5% of FVC, 54% of FEV, and 44% of PFR.

This study aimed to assess whether preoperative selective bronchospirometry could predict the degree of peroperative hypoxaemia. Twelve patients scheduled for pneumonectomy, lobectomy, wedge resection or decortication were included in the study.

The authors review the main methods designed to evaluate operability and surgical risk in candidates for chest surgery. They also report on their own experience with 135 cases operated on for thoraco-pulmonary diseases requiring surgery; in these cases, postoperative complications were studied in relation to various respiratory parameters evaluated differentially and as a whole prior to surgery. This study enabled the investigators to establish that patients with CV, FEV1, FEF25-75 and Tiffffeneau Index values below 60% of the respective theoretical reference values run a very substantial risk of postoperative complications, with a post-surgical morbidity rate of more than 60% in such patients.

Measurement of FEV1 was performed in 159 patients before and after removal of one lung. Only 41 of the postoperative values for FEV1 differed from predicted values by less than 5 percent.

Through the study of 10 patients, susceptible of operations for lung extirpation, they could so evaluate the reliability and usefulness of said two functional investigations, which can integrate and complete each other.
