Effect of Benzene on the Conduction Velocity of Peripheral Nerves in the Exposed Workers

Objective The aim was to study the effect of the benzene exposure and intoxication on the conduction velocity of peripheral nerves.[Methods] 27 observation subjects and patients with bonzene poisoning as a case group and 48 normal persons as a control group were examined. The conduction velocity of peripheral nerves was examined by electromyography.[Results] The sensory conduction velocity(SCV) of ulnar nerve and peroneal nerve is much slower,and the distal latency of median nerve is also longer in case group compared with control group(P0.05). [Conclusion] Benzene is harmful to peripheral nerve system. The sensory conduction velocity(SCV) is more valuable than the motorial conduction velocity(MCV) in revealing harmful effect of benzene on poripheral nerves.
