运动心肺功能试验对肺癌肺切除术危险性的预测

Cardiopulmonary Exercise Test Predicts Risk of Lung Resection

目的：通过对２９例具有心肺危险因素的肺癌患者进行术前肺功能及心肺运动试验检查，并对术后临床情况进行追踪，从而寻找一种更科学、准确、全面的术前预测术后并发症的方法。方法：采用德国Ｊａｅｇｅｒ公司产的体容积描记仪及运动心肺功能仪功率自行车。结果：术后无并发症组２２例与有并发症组７例，ＦＥＶ１值与残／总比在两组间无显著差异Ｐ＞００５，ＦＥＶ１％与ＭＶＶ在两组间有一定差异００２５＜Ｐ＜００５，而最大摄氧量Ｖ０２ｍａｘ、最大公斤摄氧量Ｖ０２ｍａｘ／ｋｇ及运动最大功率两组间差异有显著性Ｐ＜００１，且有并发症组的ＶＯ２ｍａｘ／ｋｇ全部＜２０ｍｌ／ｋｇ／ｍｉｎＦＥＶ１与ＶＯ２ｍａｘ／ｋｇ相关性不大ｒ＝０３５，００２５＜Ｐ＜００５。结论：术前心肺运动试验对肺癌肺切除患者是更科学、准确、全面的评估检查，而普通肺功能检查则有其局限性。

Objective: The purpose of this study was to assese the value of preoperative cardio pulmonary exercise test for the prediction of postoperative complications in lung resection candidates with high risk. Method: Patients were tested by Jaeger bodyscreen Ⅱ and ergo-screen before surgery. Results: The postoperative patients were divided into two groups: without postoperative complication and with postoperative complication. No differences in FEVI and RV/TLC (P>O.05),differences in FEVI% and MVV(O.025<P<O.O5),VO2max and VO2max/kg, and maximum load (P<O.O1) and VO2max/kg<20ml/kg/min were found in all patients with postoperative complication. Conclusion: Preoperative cardiopulmonary exercise testing was a better method for predicting postoperative complication in lung resection candidates.
