休克患者术中动脉血和呼气末二氧化碳分压的关系

Relationship between PaCO_2 and PetCO_2 in operation of shock patients

目的:研究失血休克患者术中动脉血二氧化碳分压(PaCO2)和呼气末二氧化碳分压(PetCO2)间的关系。方法:分别测定20例择期手术患者(对照组)和30例失血休克患者急诊手术中的PaCO2及PetCO2,其中估计失血量<30%的为实验Ⅰ组(18例),失血量>30%为实验Ⅱ(12例)。结果:对照组及实验Ⅰ组的患者PaCO2和PetCO2之间差异无显著性意义(P>0.05),实验Ⅱ组的患者PaCO2和PetCO2之间差异有显著性意义(P<0.01)。结论:在临床上对失血量<30%的休克患者术中的动脉血二氧化碳分压(PaCO2)和呼气末二氧化碳分压(PetCO2)间有非常好的相关性,PetCO2能反映PaCO2,而失血量>30%的休克患者术中PetCO2与PaCO2相关性差。

Objective：Study the Relationship between PaCO2 and PetCO2 in operation of hemorrhagic shock patients. Methods：Check the PaCO2 and PetCO2 seperatly in 20 selective operation patients and 30 hemorrhagic shock patients, group Ⅰ is the patients whose quantity of hemorrhagy〈30%（18 cases） group Ⅱ is the patients whose quantity of hemor rhagy〉30%（12 eases）.Results：PaCO2 and PetCO2 has no signicant difference between control group and group Ⅰ （P〉0.05）, PaCO2 and PetCO2 has signicant difference in group Ⅱ （P〈0.01）.Conclusion：There have good relationship between PaCO2 and PetCO2 in the quantity of hemorrhagy〈30%,In clinic PetCO2 can refect PaCO2,however,PaCO2 and PetCO2 have poor relationship in the patients whose quantity of hemorrhagy〉30%.
