概述

截肢术是指经骨或关节将已丧失生存能力、危害病人生命和没有生理功能的肢体截除的外科手段,是一项破坏性的手术。 术前局部处理1.1 切开引流 必须充分暴露脓腔,将坏死组织包括肌腱清理干净。1.2 局部换药 (1)干性坏疽宜暂时用无菌敷料 (或酒精纱布)包扎。(2)湿性坏疽应先切开并用凡士林油纱填塞引流。(3)创面选择敏感的抗生素纱布湿敷。 截骨平面的确定截骨平面判定应考虑:(1)营养状况。若出现皮色苍白、皮温降低、肌肉软组织萎缩菲薄、汗毛脱落等征象,说明组织营养差,愈合不良。

Frostbite is a localized cold-induced tissue injury resulting from prolonged exposure of flesh to freezing (0°C) and near freezing (2°C) temperatures.1,2 Frostbite typically affects adults between 30–49 years of age with a strong male predominance (10:1) and most commonly involves the hands and feet (>90% cases), although the face, cheeks, ears and nose may also be affected. Vasospasm and arteriovenous shunting leading to ischemia and infarction is central to the pathogenesis of frostbite and occurs on a spectrum ranging from minor exposure and pernio (chilblains), to necrosis and gangrene. The severity of frostbite is dependent on the duration of exposure. Frostbite has a predilection for those who are unable to protect themselves from adverse environments such as wilderness hikers, alcoholics and substance abusers, psychiatric patients, and the poor.

冻伤是因长期暴露于冰冻(0°C)和接近冰冻(2°C)的温度而引起的局部性冷害组织伤害。1,2冻伤通常会影响年龄在30-49岁之间的成年男性 优势(10:1),最常见的是手和脚(> 90%的情况),尽管面部,脸颊,耳朵和鼻子也可能受到影响。 导致缺血和梗死的血管痉挛和动静脉分流是冻伤发病的关键,其发生范围从轻微暴露和多年生(冰冻),坏死和坏疽开始。 冻伤的严重程度取决于暴露时间。 冻伤是偏爱那些无法保护自己免受不利环境影响的人,例如野外远足者,酗酒者和吸毒者,精神病患者和穷人。
