EVALUTION OF VENTILATORY FUNCTION OF THE PATIENTS WITH ESOPHAGEAL CANCER, SPECIAL REFERENCE TO POSTOPERATIVE PULMONARY COMPLICATION

摘要

Patients undergone the operation for esophageal cancer were examined from the viewpoint of preoperative ventilatory function and postoperative pulmonary complication. Restrictive ventilatory dysfunction alone is not indicator of postoperative complication. Short period expiratory force expressed by PEFR and FEV 1/2% is indicative. Adding this value to restrictive factor, difference between the patients with pulmonary complication and without that is clear. Postoperative ventilatory function showed marked deterioration. Postoperative blood gas A-aDo2 and shunt rate indicated miliary atelectasis which could not be detected on chest roentgenogram.
