机械通气的使用越来越广,合理应用机械通气将使重危患者抢救成功率大大增加,但不合理的应用则会给患者造成损伤或死亡。机械通气导致肺损伤的发病机制复杂,涉及到传统的气压伤、容积伤、肺不张伤,以及生物性损伤,随着对机械通气的深入研究,一些治疗观念也在发生转变,通气模式不断更新。本文就药物治疗和保护性肺通气策略的进展进行了详述。
The use of mechanical ventilation is more and more widely used, reasonable application of mechanical ventilation will greatly increase the success rate of rescuing critically ill patients, but the unreasonable application will cause injury or death to patients. The pathogenesis of mechanical ventilation leading to lung injury is complex, involving the traditional barotrauma, volume injury, atelectasis, and biological damage, with the further study of mechanical ventilation, some of the treatment concept is also changing, ventilation mode continuously Updated. This article details the progress of drug treatment and protective pulmonary ventilation strategies.
