6分钟步行试验与运动心肺功能测定预测肺癌患者术后并发症的价值

摘要

Objective: To discuss the value of combining cardiopulmonary exercise test (CPET) and 6-min walk test (6MWT)on predicting 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,O2 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 complications were all greater than 80%. Conclusion: Neither CPET nor 6MWT is better than combining both to evaluate the risk of operation and predict prognosis.%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.
