This study reviews the predictive value of maximum oxygen consumption (VO2max) and anaerobic threshold, obtained through cardiopulmonary exercise testing, in calculating peri-operative morbidity and mortality in non-cardiopulmonary thoraco-abdominal surgery. A literature review provided nine studies that investigated either one or both of these two variables across a wide range of surgical procedures. Six of the seven studies that reported sufficiently detailed results on peak oxygen consumption and four of the six studies that reported sufficiently detailed results on anaerobic threshold found them to be significant predictors. We conclude that peak oxygen consumption and possibly anaerobic threshold are valid predictors of peri-operative morbidity and mortality in non-cardiopulmonary thoraco-abdominal surgery. These indicators could potentially provide a means of allocating increased care to high-risk patients.
本研究回顾了通过心肺运动试验获得的最大耗氧量（VO2max）和无氧阈值在计算非心肺胸腹部手术围手术期发病率和死亡率方面的预测价值。一项文献综述提供了九项研究，这些研究在广泛的外科手术中调查了这两个变量中的一个或两个。七项报告了关于峰值耗氧量足够详细结果的研究中的六项，以及六项报告了关于无氧阈值足够详细结果的研究中的四项，发现它们是显著的预测指标。我们得出结论，峰值耗氧量以及可能的无氧阈值是预测非心肺胸腹部手术围手术期发病率和死亡率的有效指标。这些指标可能为将更多护理资源分配给高危患者提供一种方法。
