呼气末二氧化碳分压及动脉二氧化碳值在心肺脑复苏中的作用

Effect of end-tidal carbon dioxide partial pressure and arterial carbon dioxide value in cardiopulmonary resuscitation

目的研究呼气末二氧化碳分压（PETCO2）及动脉二氧化碳值在心肺脑复苏（CPR）中在临床意义。方法监测31例院内心跳骤停患者心肺脑复苏开始至30 min内的PETCO2值及CPR后10～15min动脉血二氧化碳值的变化。结果存活出院的11例和死亡的27例比较差异有统计学意义（P〈0.05）。结论 PETCO2可作为心肺复苏预后的一种监测指标,配合动脉血二氧化碳值对判断心肺脑复苏预后有更好的指导意义。

Objective To study the clinical significance of end-tidal carbon dioxide partial pressure（PETCO2） and arterial carbon dioxide value in cardiopulmonary resuscitation（CPR）. Methods Monitored the value of PETCO2 from the beginning of CRP to within 30 min of 31 patients with cardiac arrest and change of the arterial carbon dioxide value in 10-15 minutes later after CRP. Results In 11 discharged patients and 27 died patients, the comparative difference was statistically significance（P〈0.05）. Conclusion PETCO2 can be a monitoring index of prognostic CRP, cooperating the value of arterial carbon dioxide gives a better guiding significance to the judgment of prognostic CRP.
