观察游离腹股沟皮瓣修复拇指环形电烧伤的效果。

选取2014年6月至2020年2月郑州市第一人民医院烧伤科收治的20例拇指环形电烧伤患者为研究对象，所有患者拇指创面彻底清创后，I期采用游离腹股沟皮瓣进行修复，术后给予抗凝、抗感染、抗血管痉挛等综合治疗。术后1周和2周分别统计皮瓣存活率及创面Ⅰ期愈合率；术后6个月评价皮瓣外观、拇指运动功能及皮瓣感觉功能。

20例患者术后皮瓣成活率及创面Ⅰ期愈合率均为100.00%。皮瓣外观、质地良好，优良率为95%(19/20)。拇指功能评定综合评价：优10例，良8例，中2例，优良率90%。其中10例患者拇指可以完成对指以及拇指关节自主活动度超90°。皮瓣两点辨别觉为(8.2±1.4) mm，皮瓣感觉恢复良好。
