周围神经火器伤

Firearm injuries of peripheral nerve

弹片伤是周围神经损伤主要致伤因素。由于早期难以判定损伤神经范围，同时伤口污染严重，因此禁止一期修复损伤神经。外科修复应在伤后 3～ 6个月后，肌电图等检查确定神经功能无恢复方可进行。本文回顾了近年来周围神经火器伤救治与研究的进展，并展望了今后的发展。

Firearm injuries of peripheral nerve was more common in wartime. Shell fragments were major etiologic factors of these injuries.Many injuring nerves also preserved partial continuity. Primary repair of such injuries was contraindicated, because it was impossible to determine the exact proximal and distal extent of injury and the contaimination of the wound was more severe. Surgical management of these injuries could be performed three to six months after injuries until electromyoneurographic testing and other physical examine did not find recover of the nerve function. Recent progress of clinical treatment and experimental study of these injuries were reviewed and the prospect was presented in this paper.
