目的 探讨家免电击伤后早期坐骨神经的病理和肌电生理变化及其规律。 方法 建立高压电实验装置 ,采用微型数字储存式记录器 ,经计算机回放分析获得测定电流值 ,并进行肌电生理与病理学检测。 结果 5 0Hz时神经组织的平均等效电阻值为 (5 .99± 0 .88)kΩ ,电流密度平均值为 83.5mA/cm2 。肌电生理及病理学检查显示 ,坐骨神经均有不同程度的损伤。 结论 高压电击伤后 。
Objective To explore the pathological and myoelectric*Mphysiological changes and the mechanism of the early postburn sciatic nerve injury by high voltage electricity in rabbits. Methods Apparatus producing high electricity was established with a special*Mdesigned microrecorder of digital reserve. The electrical current values were determined by computer responsive analysis system with the concomitant determination of myoelectric*Mphysiology and pathomorphology. Results When the current was set to be 50 HZ, the average indentical resistance value of the nerve tissue was (5.99±0.88)kΩ and the average current value was 83.5mA/cm 2. There exhibited different degrees of sciatic nerve injury when examined by myoelectric*Mphysiological and pathophysiological measures. Conclusion Peripheral nerve could be injured by current of high voltage electricity.
