ESC 2017:CAAM为院外心脏骤停心肺复苏行ETI还是BMV给出答案

心脏骤停是导致健康人死亡的主要原因,在美国每年有300000多人死于心脏骤停,在欧洲由200000多人。只有不到10%的院外心脏骤停患者幸存下来。

已知气道管理与气管插管(ETI;图1)是院外心脏骤停患者心肺复苏的标准护理方法。但是其效果受到国际注册的回顾性分析结果的质疑,回顾性分析显示复苏阶段性ETI患者的存活率较低。研究提出面罩通气(BMV; 图 2)或更安全且更有效。



CAAM试验是一项前瞻性、随机、对照、多中心研究,研究对比了ETI与BMV对院外心脏骤停患者进行气道管理时的生存率。

研究共纳入了2040名院外心脏骤停患者,来自法国的15个中心和比利时的5个中心。患者随机分入BMV组和ETI组。主要终点为心脏骤停28天后具有良好神经功能(定义为GP-CPC分级≥2)患者的生存率。

次要终点为循环自主恢复率、入院患者的生存率和不良反应(包括操作失败、操作困难及胃内容物反流/误吸)。


结果显示,两组28天具有良好神经功能的生存率相同(BMV4.2% VS. ETI 4.3%)。然而,BMV组失败率高于ETI组(6.7% VS. 2.1%)。此外,BMV组胃内容物反流/误吸发生率明显高于ETI组(15.2% vs. 7.5%)。

总之,该研究结果表明,院外心脏骤停患者行心肺复苏时采取BMV的方法其安全性低于ETI。因此,研究人员建议院外心脏骤停患者行心肺复苏的标准疗法仍为ETI。
