围手术期氧疗的研究进展

Research progress in perioperative oxygen therapy

大多数围术期手术患者常规接受氧疗,以预防或治疗可能发生的低氧血症.世界卫生组织关于减少手术部位感染的指南建议围手术期给予高浓度氧气,然而氧疗和高氧血症对呼吸和心血管系统也有不利影响.一些临床研究报道围手术期高浓度氧疗与更差的临床结局之间存在关联.本文对围手术期氧疗的相关研究及指南进行综述,为更加合理、安全地进行围术期氧疗提供一定参考.

Most perioperative patients undergo routine oxygen therapy to prevent or treat potential hypoxemia.The World Health Organization guidelines for reducing surgical site infection have recommended the administration of high concentration of oxygen during the perioperative period.However,oxygen therapy and hyperoxemia also have adverse effects on the respiratory and cardiovascular systems.Some clinical studies have reported an association between high-dose perioperative oxygen therapy and worse clinical outcomes.This article reviews the relevant research and guidelines on perioperative oxygen therapy,providing reference for more reasonable and safe perioperative oxygen therapy.
