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%.
我们研究了肺切除术后并发症与运动试验结果及其他因素之间的相关性。对64例患者进行了术前运动试验；其中44例行肺叶切除术，6例行双叶切除术，14例行全肺切除术。与术后并发症相关的结果有右心室/体表面积（p<0.001）、右心室/肺总量（p<0.005）、每分通气量/二氧化碳排出量（p<0.001）和氧耗量/每分通气量（p<0.001）。男性的并发症比女性多（p<0.001）。有心血管疾病、肺部疾病和/或糖尿病既往史的患者比没有这些病史的患者发生并发症的几率更高（p<0.05）。根据这些结果，我们得出结论，有以下一项或多项结果的患者术后发生并发症的几率更高。1. 最大氧耗量/每分通气量小于40ml/l。2. 每分通气量/二氧化碳排出量大于4.0l/ml。3. 右心室/体表面积大于1.5l/m2。4. 右心室/肺总量大于45%。
