Pulmonary function in the patients submitted to lung exeresis.

The effects of lung surgery on respiratory function were investigated in 80 patients; 17 patients were submitted to left pneumonectomy (LPN); 11 patients were submitted to right pneumonectomy (RPN); 7 patients underwent a left upper lobectomy (LUL); 16 patients a left lower lobectomy (LLL); 17 patients were submitted to right upper lobectomy (RUL); 12 patients underwent right lower lobectomy (RLL). All patients were submitted to spirometry and arterial blood gas analysis. The effects of lung surgery on respiratory function depends upon the extent of the resected tissue.
