术中超强电刺激在产瘫治疗中的应用

Application of intraoperative extra strong electrical stimulation in the treatment of brachial plexus birth palsy

目的探讨术中超强电刺激对不完全产瘫的治疗价值。方法2008年7月至2011年9月，对9例产瘫在进行神经松解后，术中给予超强肌电刺激，分别测定超强电刺激前后复合肌肉动作电位的潜伏期、波幅，并比较其改善程度。结果9例中7例潜伏期改善，8例波幅改善。经神经超强电刺激前、后其潜伏期缩短差异百分比为1．06％～39．77％，平均为8．02％；波幅提高差异百分比为2．70%-400．00％。平均为185．97％。术后2周内随访，8例患儿受刺激神经根干所支配相应肌肉有可见的功能改善。结论超强电刺激可作为一种提高产瘫松解手术疗效的辅助治疗方法。

Objective To explore clinical value of intraoperative extra strong electrical stimulation in the treatment of birth brachial plexus palsy. Methods From July 2008 to September 2011, intraoperative extra strong electrical stimulation was applied in 9 cases of incomplete birth brachial plexus palsy after neurolysis. The latency and amplitude of compound muscle action potentials before and after electrical stimulation were recorded and the extent of improvement was compared. Results The latency was improved in 7 cases with 8.02% in average, amplitude in 8 cases with 185.97% in average. The related nerve recover partial motor function in 8 cases in 2 weeks after operation. Conclusion Intraoperative extra strong electrical stimulation is a effective assistant technique to promote motor functional recovery of birth brachial plexus palsy.
