[Respiratory function on exercise as a predictor of complications after lung resection].
We studied the correlation between the complications after pulmonary resection and the results of exercise testing and others. The exercise testing was performed preoperatively on 64 patients; 44 lobectomies, 6 bilobectomies and 14 pneumonectomies. The results which had the correlation with postoperative complications were RV/BSA (p less than 0.001), RV/TLC (p less than 0.005), VE/VCO2 (p less than 0.001) and VO2/VE (p less than 0.001). Men had more complications than women (p less than 0.001). And the patients with the past histories concerning cardiovascular disease, pulmonary disease and/or diabetes had more chances of complications than the patients without those histories (p less than 0.05). Judging from these results we concluded that the patients with one or more of the following results had more chances of postoperative complications. 1. maximum VO2/VE was less than 40 ml/l. 2. VE/VCO2 was more than 4.0 l/ml. 3. RV/BSA was more than 1.5 l/m2. 4. RV/TLC was more than 45%.
