休克时,微循环流碍是灌障其发病的中心环节,山莨菪碱(654-2)作为改善微循环灌流的血管活性药物用于休克的实验研究和临床治疗已有不少报导,其机理正在探索中。为了解山莨菪碱在失血性休克时对血气改变的有益效应,本实验对照观察了失血性休克时的血气参数变化及山莨菪碱对此变化的影响。方法是选用健康家兔20只,体重在2.5—3公斤, Shock, microcirculation is the central link in the pathogenesis of cerebral infarction. Anisodamine (654-2) has been reported as an experimental and clinical study on the improvement of microcirculation perfused vasoactive drugs for shock. The mechanism of microcirculation Being explored. In order to understand the beneficial effects of anisodamine on blood gas changes during hemorrhagic shock, we observed the changes of blood gas parameters during hemorrhagic shock and the effect of anisodamin on the changes. Method is to use healthy rabbits 20, weighing 2.5-3 kg,
