Complications after major surgery are an important cause of mortality and morbidity, especially when they affect the lungs.¹ So-called postoperative pulmonary complications occur more frequently than do cardiac complications in patients who have non-cardiac surgery, with reported incidences as high as 40%.² One in every seven patients who develop postoperative pulmonary complications dies before hospital discharge, and survivors have sustained reduced functional status.^1,2 Thus, any intervention that affects the occurrence of postoperative pulmonary complications could have a substantial impact.

麻醉期间是否应休息或打开肺部以防止术后并发症？

大手术后的并发症是死亡率和发病率的重要原因，尤其是当它们影响肺部时。¹在非心脏手术患者中，所谓的术后肺部并发症比心脏并发症发生的频率更高，据报道其发生率高达40％。²发生肺部并发症的患者中，七分之一在出院前死亡，幸存者的功能状态持续下降。^1,2因此，任何影响术后肺部并发症发生的干预措施都可能产生重大影响。
