儿童臀肌注射药物后出现跛行在临床上,尤其是在基层医疗实践中并不少见,临床症状多表现为发热、肢体麻木、无力、足下重、患侧腱反射减弱或消失。因症状类似小儿麻痹症,故常易误诊。本文对21例肌注后坐骨神经损伤的神经肌电图检查结果作一分析总结。 1 资料与方法 本组21例,女性9例,男性12例;年龄1～16岁,平均5.3岁;病程半月～2年不等,平均3.7个月。使用日本MEM-3202型肌电图机,用同心针电极分别对患侧胫前肌、腓肠肌进行常规的肌电三态观察,测定胫神经、腓总神经的运动传导速度及双侧H反射。
Children with gluteal injection of drug limp in clinical practice, especially in primary care practice is not uncommon, clinical symptoms and more manifested as fever, limb numbness, weakness, fullness, ipsilateral tendon reflexes diminish or disappear. Because of symptoms similar to polio, it is often misdiagnosed. In this paper, 21 cases of intramuscular injection of sciatic nerve injury after electromyography results for an analysis summary. 1 Materials and Methods The group of 21 cases, 9 females, 12 males; aged 1 to 16 years, mean 5.3 years; duration of half a month ~ 2 years, an average of 3.7 months. Using the Japanese MEM-3202 electromyography machine, the normal electromyographic tri-state was observed on the ipsilateral tibialis anterior muscle and the gastrocnemius muscle respectively with concentric needle electrodes. The velocity of tibial nerve and common peroneal nerve and the bilateral H-reflex were measured.
