全身麻醉诱导时面罩通气模式对胃胀气的影响

The influence of mask ventilation model on gastric insufflation during anesthesia induction

反流误吸因其高致病率、高致死率而受到人们关注,但忽视了麻醉诱导期间加压面罩通气导致胃内进气而增加反流误吸风险。目前既能保证通气效果又能避免胃内进气的最佳通气模式尚无定论。文章就胃进气的原因和机制、麻醉诱导期间通气模式与胃进气的关系以及在围手术期所能采取的防治措施进行综述,介绍近年来全身麻醉诱导期间胃胀气相关国内外研究进展。

Regurgitation and aspiration have attracted people's attention because of its high morbidity and mortality.However,during the anesthesia induction period,the problem of increased risk of regurgitation and aspiration by pressurized mask ventilation is ignored.At present,the best ventilation mode that can not only ensure the ventilation effect but also avoid gastric insufflation is undefined.This review summarizes the causes and the mechanisms of gastric insufflation,the relationship between ventilation modes during anesthesia induction and gastric insufflation,and the preventive and therapeutic measures that can be taken during the perioperative period.
