心肺复苏时呼气末CO_2监测的临床意义

THE VALUE OF ENDTIDAL CARBON DIOXIDE DURING CARDIOPULMONARY RESUSCITATION

目的探讨呼气末二氧化碳浓度（ＥＴＣＯ２）在心肺复苏时的临床意义。方法观察１２例院内心跳骤停患者心肺复苏时气管插管后ＥＴＣＯ２的变化。结果①自主循环恢复的８例气管插管后ＥＴＣＯ２明显高于未恢复的４例ＥＴＣＯ２（２．０９％Ｖｓ１．１３％，Ｐ＜０．０１）。②复苏成功的８例自主循环恢复后ＥＴＣＯ２迅速升高达３．４１％，与插管后即刻比较差异有高度显著性（Ｐ＜０．０１）。结论ＥＴＣＯ２不仅可作为心肺复苏的一种监测指标，而且对判断预后有一定指导意义。

Objective To estimate the value of endtidal carbon dioxide(ETCO_2)monitouing during cardiopulmonary resuscitation(CPR).Method Changes of ETCO_2 in 12 cardiac arrest patients after endotracheal intubation during CPR were observed.Result ①The average ETCO_2in eight patients with the return of spontaneous circulation(ROSC) was significantly higher than that in four patients without the ROSC (2.09% Vs 1.13%,P<0.01).②The ETCO2in 8 patients with successful rescuscitation after ROSC increased abruptly to 3.41%,and had a significant difference than that after endotracheal intubation (P<0.01).Conclusion ETCO2 not only can be a valuable monitoring indicator during CPR,but also has prognostic value for CPR.
