电烧伤截肢术115例次分析

A report of 115 cases of amputation after electric injury

目的 分析电烧伤截肢术的特点及方法。 方法 统计了 115例次电烧伤截肢术 ,就其适应症、截肢部位、手术方法及转归进行了探讨。 结果 肢体电烧伤截肢率为 :上肢 45 .4% ,下肢 14.9%。截肢适应症包括 :肢体完全坏死 ;肢体继发坏死如血管继发栓塞、出血、断裂致缺血坏死 ;组织严重损伤无法修复等。截肢平面以前臂中、短残肢最多 ,残肢Ⅰ期愈合率为 6 3.5 %。 结论电烧伤截肢需慎重选择适应症、截肢平面及正确的手术操作 ,以保证有良好的截肢残端 ,适应安装假肢 。

Objective To analyze the main features of amputation subsequent to electric injury. Methods One hundred and fifteen cases of amputation were analyzed with the purpose to define the indication, the optimal level, operational methods and the prognosis. Results The incidences of amputation in this group were 45.4% for upper and 14.9% for lower extremities, respectively. The indications were total necrosis of the extremities, secondary necrosis of the extremities due to the thrombosis, bleeding and rupture of the major supplying arteries and failure to restore severely injured tissue. The commonest amputation levels were the midthird and the upper third of the forearms. The primary healing rate was 63.5%. Conclusion It was very important to identify the optimal indications, the proper levels and operational methods for the amputation after electric injury, so as to make stumps more suitable for the installation of artificial limbs to restore better function.
