目的探讨正己烷慢性中毒患者的临床和肌电图特点.方法对诊断为慢性正己烷中毒的9例患者的临床表现和肌电图进行分析.结果临床表现主要为肢体无力、感觉异常,下肢明显.肌电图检查异常率为100.00%,感觉神经传导速度均减慢为33.33%,运动神经传导速度均减慢为88.89%,远端潜伏期延长为100.00%,肌电图示失神经支配为33.33%.结论周围神经病变是慢性正己烷中毒的主要临床表现.肌电图表现以周围神经远端髓鞘变性为主,运动较感觉更易受累,下肢较上肢易受累,神经损害程度与接触时间长短有关.

Objective To investigate the characteristics of the clinic manifestations and the electromyogram changes in patients with chronic N2hexane intoxication. Methods The clinic manifestations, the electromyography and nerve conduction velocities were analyzed in 9 patients with N2hexane intoxi2 cation. Results The main clinical manifestations of the disease were acroparesthesia and asthenia, especially in legs. The abnormality rate of electromyography in patients with N2hexane intoxication was 100%. The conduction velocity of the sensory nerve and the motor nerve decreased at a rate of 33.33% and 88.89% respectively. The distal latencies were prolonged( 100% ). The denervated electromyogram was 33.33%. Conclusion The main clinical manifestations of the disease were Peripheral neuropathy. The chronic N2hexane intoxication mainly led to the imparement, especially in the distal region of the motor nerve in legs,and the damages of the nerve could be related to the duration of exposure to N2hexane.
