巯甲丙脯酸对家兔失血性休克的作用

家兔26只,复制晚期失血性休克模型后,随机分为巯甲丙脯酸治疗组和对照组。治疗组给予巯甲丙脯酸1mg/kg及配合输液输血。治疗后1小时,平均动脉血压(MABP)、中心静脉压(CVP)、平均肾血流量(MRBF)均见明显回升,血小板聚集率显著降低,肠系膜微循环有显著性改善,治疗后3小时上述各项指标均接近正常水平。5小时存活率为91.7%。与对照组相比较差别有高度显著性(P<0.01)。本研究结果表明:巯甲丙脯酸用于晚期失血性休克,可使微血管扩张,微循环灌注增加,回心血量增加,血压回升,具有良好的抗失血性休克作用。

The effect of captopril on rabbits hemorrhagic shock

This paper reported the effect of captopril (SQ14225) on rabbits hemorrhagic shock. After late hemorrhagic shock model (MABP 40mmHg, maintained for 90min) was replicated, 26 rabbits were divided randomly into a captopril-treated group (n=13) and a control group (n=13). In the treated group, captopril(1mg/kg) was infused with normal saline (15ml/kg), low molecular dextran (15ml/kg)and shed blood, an hour later, the MABP, CVP and renal blood flow rose markedly, the platelet aggregation was significantly lowered and mesenteric microcireulation was improved remarkably. Three hours later, the various indexes mentioned above returned almost to normal (before the shock). The survival rate in 5 hours was 91.7%. The difference between the control and the treated group was quite significant (P<0.01). The results demonstrated that captopril has good antishock effect.
