摘　　要：目的:探讨运动心肺功能测定(CPET)与6分钟步行试验(6MWT)联合检测预测术后并发症发生率的价值。方法:收集新入院需行肺癌切除术的患者133例,入院后行运动心肺功能测定及6分钟步行试验,并记录相应指标。结果:肺叶切除术后并发症发生组峰值摄氧量占预计值百分比(VO2%P)、公斤摄氧量(VO2/kg)、无氧阈(AT)、氧脉搏占预计值百分比(O2pulse%P)、呼吸频率(BF)及6MWT均明显低于无并发症组,差异有统计学意义(P<0.05),当CPET与6MWT中预测术后肺部并发症的敏感指标(VO2%P≤50%,6MWT≤300 m)结合起来时,其预测术后肺部并发症的敏感性与特异性均>80%。结论:当CPET与6MWT联合检测时,优于任何单一方式评估手术适应征及预测手术风险。Objective： To discuss the value of combining cardiopulmonary exercise test （CPET） and 6-min walk test （6MWT）on pre- dicting postoperative complications. Methods： 6MWT and CPET were carried out in 133 patients with lung cancer. Results： In inpatients with postoperative complications group, the indexes of cardiopulmonary exercise function ： VO2 %P, VO2 %/kg, AT, 02 pulse%P, BF and 6MWT were significantly lower than those in non-postoperative complications group （P〈0.05）. When combining the sensitive indexes of CPET and 6MWT （VO2%P ≤ 50%, 6MWT ≤300 m）, the sensitivity and specificity of predicting incidence rate of postoperative compli- cations were all greater than 80%. Conclusion： Neither CPET nor 6MWT is better than combining both to evaluate the risk of operation and predict prognosis.
