OBJECTIVE
To explore the pathological and myoelectric-physiological 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-designed microrecorder of digital reserve. The electrical current values were determined by computer responsive analysis system with the concomitant determination of myoelectric-physiology 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) k omega and the average current value was 83.5 mA/cm2. There exhibited different degrees of sciatic nerve injury when examined by myoelectric-physiological and pathophysiological measures.
CONCLUSION
Peripheral nerve could be injured by current of high voltage electricity.
目的
探讨家兔高压电烧伤后早期坐骨神经损伤的病理及肌电生理变化及其机制。
方法
采用特制的数字存储微记录仪建立高压电发生装置。通过计算机响应分析系统测定电流值，并同时测定肌电生理和病理形态学。
结果
当电流设定为50赫兹时，神经组织的平均等效电阻值为(5.99±0.88)千欧，平均电流值为83.5毫安/平方厘米。通过肌电生理和病理生理检测发现坐骨神经有不同程度的损伤。
结论
高压电电流可导致周围神经损伤。
