目的 观察氨基胍(AG)在失血性休克复苏中的作用机制.方法 采用股动脉放血法复制家兔失血性休克模型,将20只家兔随机均分为生理盐水复苏对照组和AG复苏组;用Pclab生物信号采集系统分别记录休克前、休克30 min、休克150 min、复苏30 min、复苏180 min的血流动力学参数,并用硝酸还原酶法测定相应时间点的血清一氧化氮(NO)水平.结果 两组复苏前动脉收缩压(SAP)、心率(HR)、平均动脉压(MAP)、左心室收缩压(LVSP)、心室内压最大上升和下降速率(±dp/dt max)等血流动力学参数与血清NO含量比较差异均无统计学意义.与休克前比较,两组休克30 mid和150 min血流动力学参数显著下降,NO含量显著升高(P＜0.05或...

OBJECTIVE: To explore the effect of aminoguanidine (AG) on hemodynamics and nitric oxide (NO) in hemorrhagic shock in rabbit. METHODS: Shock was produced in twenty rabbits by femoral artery blood letting, and they were randomly divided into two groups with treatment with saline (control group) or AG (each n=10). Pclab system and nitric acid reductase methods were performed to detect hemodynamics parameters and NO levels at preshock, postshock (30 minutes and 150 minutes) and 30 minutes and 180 minutes after resuscitation respectively. RESULTS: No significant differences were observed in hemody...
