血气分析及其碱剩余在心肺复苏中的指导意义

The Guiding Significance of Blood Gas Analysis and Standard Base Excess in Cardio-pulmonary Resuscitation

目的:探索血气分析碱剩余在心肺复苏过程中的指导意义。方法:采用随机抽取方法,以2012-2014年院外呼吸心跳骤停的患者为研究对象,分析血气分析相关项目与心肺复苏效果的关联性,同时分析碱剩余在心肺复苏成功组与失败组中差异性。结果:碱剩余均为负值,血气分析中标准碱剩余与心肺复苏存在关联性(P=0.018,OR=0.527),复苏成功组与失败组标准碱剩余比较差异有统计学意义(P=0.021),其复苏成功组标准碱剩余绝对值(15.00±2.18)mmol/L低于失败组(19.80±1.77)mmol/L。同时SBE绝对值≤20 mmol/L复苏成功率高于SBE绝对值>20 mmol/L,差异有统计学意义(P=0.013)。结论:标准碱剩余与心肺复苏存在关联性,其绝对值高于20 mmol/L,不易复苏成功。

Objective： To explore the guiding significance of blood gas analysis and standard base excess in cardio-pulmonary resuscitation.Method ： The patients which were cardiopulmonary arrest out-hospital were randomly taken as research objects, the relationship between the items of blood gas analysis and the outcome of cardio-pulmonary resuscitation were finded out, include the difference of standard base excess between the two teams that had different outcome of CPR.Result： The value of BE all were negative. SBE was relevant to CPR（P=O.O18, OR=0.527）, and had difference in the anabiosis success team and anabiosis unsuccess team（P=0.021）, and the absolute value in anabiosis success team was （15.0 ± 2.18）mmol/L, it was lower than the one of anabiesis fail team （19.8 ± 1.77）mmol/L.The success rate of the absolute value of SBE under or equal 20 mmoUL was higher than the absolute value of SBE above 90 mmol/L（P=0.013）.Conclusion： SBE is relevant to CPR.When the value of SBE above 20 mmol/L, the patient is hard to revive.
