目的 研究药物注射致坐骨神经损伤的临床及肌电图特点。 方法 收集药物注射致坐骨神经损伤患者 3 7例 ,全部患者均进行了神经肌电图检查 ,部分病人进行了随访观察。对此患者的临床及肌电图进行回顾性分析。 结果 患者注射抗生素等药物当时或注射后很快出现注射下肢不同程度的感觉和运动功能障碍。此事件多发生在乡村卫生室或小诊所 ,患者多为儿童 ,其预后尚可。神经肌电图检查患肢腓总神经传导及体感诱发电位PF -CE波间期与正常值相比较具有显著性差异 (P <0 .0 0 1)。体感诱发电位PF -CE波间期检查异常是该病典型的神经电生理表现。 结论 药物注射致坐骨神经损伤临床及肌电图有其典型的特点 ,掌握其规律及特点 ,对实际临床法医学鉴定有很大的应用价值。
Objective To study the clinical and EMG characteristics of sciatic nerve injury caused by drug injection. Methods Thirty-seven patients with sciatic nerve injury were collected by drug injection. All patients were examined by electromyography. Some patients were followed up. The clinical and EMG of this patient were retrospectively analyzed. Results Patients with antibiotics and other drugs injection or injection immediately after injection of varying degrees of sensory and motor dysfunction. This incident occurred in rural clinics or clinics, mostly children, the prognosis is acceptable. Neuromyo-EMG examination of the limbal common peroneal nerve conduction and somatosensory evoked potential PF-CE wave interval compared with the normal significant difference (P <0.001). Somatosensory evoked potential PF-CE wave interval abnormalities is a typical neuroelectrophysiological manifestations of the disease. Conclusion The injection of sciatic nerve injury caused by clinical and EMG has its typical characteristics, to grasp the rules and characteristics of the actual clinical forensic identification has great value.
