Four hundred and twenty-three cases of the aged patients, who underwent general and regional anesthesia from January 1972 to July 1974 were studied. Aged patients were classified into three hundred and twenty-eight cases of the old age group, who were from 65 to 74 yearold, and ninety-five cases of the advanced age group, who were over 75 yearold. Various factors which influenced the occurrence of the postoperative pulmonary complication were studied and the following results were obtained :<BR>1. It was found that the incidence of the postoperative pulmonary complication was correlated with age, sex, habits of smoking, emergency operation, site of operation, history of the thoracic surgery and obstructive symptome of the respiratory tract, the kind of an-esthesia, operation time and pulmonary function test.<BR>2. The arterial Po2 continued to decrease from the day of the operation, in both the old age and the advanced age group, reaching to the lowest value at the 3rd postoperative day, at the 7th postoperative day, the arterial Po2 returned nearly to the preoperative level in the old age group. However, the recovery of the arterial Po2 was not enough in the advanced age group. There tendency were marked in the cases followed by the lung com-plication, especially, in the advanced age group. Fall of the arterial Po2 had been found usually, before the occurrence of the lung complication was confirmed by X-ray examination.
