THE SURGICAL TREATMENT OF PULMONARY EMPHYSEMA.

Emphysema may be focal or multifocal. In either type an area of disease may enlarge and reduce the function of adjacent lung.Thirty patients who required treatment for emphysema and its complications are described. Fifteen patients with focal emphysema that did not constitute a space-occupying lesion required operation because of recurrent pneumothorax or infection in the affected area. The results were excellent. Ten patients with focal emphysema and progressive "space occupation" complained of moderate but increasing dyspnea. Removal of the enlarging lesion resulted in marked improvement. Five patients with multifocal emphysema and progressive space occupation in one focal area suffered from severe dyspnea and poor general health. The space-occupying lesion was removed by lobectomy. The results, measured by pulmonary function tests and subjective improvement, were rewarding in most cases. No patient with multifocal emphysema but without a space-occupying lesion under-went operation.

THE VALUE OF PULMONARY FUNCTION STUDIES IN THE ASSESSMENT OF PATIENTS FOR CARDIAC SURGERY.

Preoperative pulmonary function, intracardiac pressures and degree of dyspnea were related to the incidence of postoperative respiratory insufficiency in 102 adult patients who underwent cardiac surgery. The purpose was to seek a reliable method of prognosticating the risk of postoperative respiratory insufficiency, especially after the use of cardiopulmonary bypass. When the heart-lung pump was used, 24 of 30 patients with a vital capacity less than 80% of the predicted normal developed respiratory insufficiency, whereas only eight of 41 patients with a normal vital capacity had this complication. In 26 patients where the vital capacity and gas diffusion were both normal, only three developed postoperative respiratory insufficiency. Other single or combined pulmonary function abnormalities, including tests of the mechanics of breathing, were of no greater value in predicting the postoperative course. The degree of dyspnea and the level of intracardiac pressures, although sometimes helpful, were often misleading.
