为了解环氧乙烷对人体的危害 ,对车间中环氧乙烷进行了浓度测定 ,并对接触者进行了肌电图观察。接触者主要表现为肢体麻木、肌无力等症状 ,经肌电图检查 ,其小指展肌、胫骨前肌、腓肠肌收缩时 ,运动单位平均时限明显延长 ,显著多于对照组。运动神经多相电位的增多与接触时间呈正相关。 In order to understand the harm of ethylene oxide to the human body, the concentration of ethylene oxide in the workshop was measured, and the contact persons were observed by EMG. The contact was mainly manifested as limb numbness, muscle weakness and other symptoms by EMG examination, the little finger abductor muscle, tibialis anterior muscle, gastrocnemius contraction, the average duration of exercise units was significantly longer, significantly more than the control group. The increase of motor nerve polyphase potential was positively correlated with the contact time.
