[An experimental study of the sciatic nerve injury by high voltage electricity in rabbits]
1Department of Burns and Plastic Surgery, Shanghai Electrical Power Hospital, Shanghai 200050, P. R. China.
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.
