【摘要】 目的分析引起新生儿分娩性臂丛神经损伤(臂麻痹)的原因、类型及预后。方法对112例患儿作回顾性分析,于1995年作随访调查(查体、信函及(或)电话),后遗症者作肌电图检查。结果臂麻痹见于:①胎位不正(臀位居多)、头盆不称(胎儿大)占42.9%;②顺产、宫内窘迫、滞产等占33.9%;③用助产操作、剖宫产等占23.2%;④其他:第2～3产占26.8%及低出生体重儿占18.8%。臂麻痹前臂型49.1%、上臂型26.8%、全臂型24.1%;单侧71.4%、双侧28.6%;合并膈神经麻痹2例。预后:住院期间恢复率27.4%(儿院29/106例);出院时未愈77例,随访21例,未愈4例(19%),年龄2～8岁,全臂型肌萎缩,肌电图为神经原性损伤,其余多数在1岁内恢复,最晚在6岁。结论臂麻痹后遗症19%,应重视预防,如果3～6个月毫无改善,神经修补术可望获得部分改善。更多还原

【Abstract】 Objective To study the cause,type,and prognosis of newborn brachial palsy. Methods Review and analysis the clinical feature of 112 newborn cases with brachial plexus palsy and follow up for 2～8 years by clinical observation or letter or telephone,EMG was done for the cas- es with handicaps.Results Most cases happened in the conditions of abnormal fetal position, cephal opelvic dispropotion,fetal distress and prolonged labor and mechanical interference with deliv- ery,etc.The patterns of brachial palsy included lower arm palsy (49.1%) upper arm palsy (26.8%) and entire arm palsy (24.1%).Unilateral involvement accounted for 71.4%.29 babies recovered completely before discharge.21 cases were followed up.4 cases (19%) with entire arm palsy had per- manent damage,at the age of 2～8,EMG showed myogenic injury.The rest 17 cases returned to nor real function,most cases recoverd within 1 year of age.Conclusion 19% of cases with brachial palsy had sequelae,prophylaxis is important.If the paralysis persists without improvement for 3～6 months,neuroplasty offer hope for partial recovery.更多还原
