摘要
目的：了解肌肉注射损伤坐骨神经程度及预后的关系；方法：用Ｊ—Ｄ２型的肌电图仪对４３例肌肉注射损伤坐骨神经患者进行常规肌电图检查；结果：肌肉注射直接损伤坐骨神经和间接药物浸润性损伤有插入电位延长、肌休状态有纤颤正相电位，轻收缩无多相电位时限不长，最大收缩单纯相或单纯混合相。较重患者轻收缩无运动单位电位。感觉及运动神经传导速度变慢；
Objective:To study the relationship between electromyogram (EMG)and the degree of the injury of sciatic nerve.Methods:The routine EMG of 43 cases with the injury of sciatic nerve caused by intramuscular injection was measured using myoelectric apparatus(Model:J-D 2).Results:The prolonged insertion potential,fibrillation positive sharp wave potential in a resting state of muscle ,polyphasic potential and short time limit in a state of slight contraction of muscle ,and discrete activity pattern or both discrete activity and reduced interference pattern in a state of maximal contraction were observed in the EMG of direct injury and indirect medicine infiltraction injury of sciatic nerve caused by intramuscular injection.There was no motor unit potenitial can be observed in the state of slight contraction in the EMG of severe injury of sciatic nerve.Sensory and motor nerve conduction velocity reduced.Conclusion:The EMG examination is helpful to confirm the existence of direct or indirect neurogenous injury of sciatic nerve.
