应用家兔失血性休克模型,观察不同量平衡液的扩容效果,为挽救失血性休克确定适宜扩容量提供依据。 实验用雄性家兔21只,20％乌拉坦麻醉,用贮血瓶自颈动脉放血使血压维持40mmHg1小时。然后休克对照组(n=5)不予治疗观察2.5小时;三倍组(n=7)输挂失血量3倍的含碳酸氢钠平衡盐溶液;6
Hemorrhagic shock model of rabbits was used to observe the effect of volume expansion of different amounts of balancing fluid to provide basis for rescuing hemorrhagic shock. Twenty-one male rabbits were anesthetized with 20% urethane, and the blood pressure was maintained at 40mmHg for 1 hour by blood excretion from the carotid artery using a blood reservoir bottle. The shock control group (n = 5) was treated for 2.5 hours without treatment; the triple-fed group (n = 7) was given sodium bicarbonate balanced salt solution with 3 times the amount of blood loss;
