本实验以一定重力致兔左侧股骨中下1/3处粉碎性骨折造成创伤性休克,连续监测血压4hr;治疗组于创伤后2hr自颈外静脉注入654-2(5mg+10ml生理盐水/kg);预防组于创伤前由耳缘静脉注入654-2(2mg/kg)余同治疗组;另取4只家兔作为假手术组。结果显示,对照组家兔创伤后4hr末,血压降至休克前的41%,低于假 In this experiment, rabbits suffered from traumatic shock caused by comminuted fractures of the lower left femur of the rabbit with a certain gravity, and blood pressure was continuously monitored for 4 hours. The treatment group was injected with 654-2 (5 mg + 10 ml saline) 2 hours after the injury from the external jugular vein. In the preventive group, 654-2 (2 mg/kg) was administered into the treatment group before the wound; another 4 rabbits were taken as the sham group. The results showed that at 4 hrs after wounding in rabbits in the control group, blood pressure dropped to 41% before shock and was lower than
