摘要(Abstract):
目的以电击致犬心室颤动建立的心搏骤停动物模型为研究对象,研究在心肺复苏(CPR)模式下犬潮气末二氧化碳分压(PETCO2)和冠状动脉灌注压(CPP)的变化及相关性。方法选健康杂种犬36只随机分为三组:4 min胸外复苏组、4 min开胸复苏组、8 min开胸复苏组。每组12只犬,雌、雄各半,致颤前及复苏过程中对PETCO2及CPP进行监测。根据自主循环恢复(ROSC)情况,比较复苏成功和复苏失败犬的CPP和PETCO2。结果 4 min胸外心肺复苏(CCCPR)时CPP与PETCO2的Pearson相关系数为0.992,P<0.05,CPP与PETCO2呈线性正相关。4 min开胸心肺复苏(OCCPR)时CPP与PETCO2的Pearson相关系数为0.937,P<0.05,CPP与PETCO2呈线性正相关。8 min OCCPR时CPP与PETCO2的Pearson相关系数为0.952,P<0.05,CPP与PETCO2呈线性正相关。4 min胸外复苏组ROSC 8只(66.7%),4 min开胸复苏组ROSC 12只(100%),8 min开胸复苏组ROSC 7只(58.3%)。在按压复苏1、2、5、10、15、20 min时,自主循环恢复组与失败组的CPP和PETCO2分别比较,两组之间差异均有统计学意义(P<0.05)。结论心肺复苏期间CPP与PETCO2关系密切,呈线性正相关,因此可以用PETCO2参数评价心肺复苏的预后效果。
