文档介绍：电烧伤和化学烧伤
1
一、电烧伤
损害机制
伤情决定因素:接触时间、电流强度、电流性质、电流径路等。
不同组织的局部损害程度不同。
“跳跃式”深度烧伤。
2
临床表现
全身性损害:恶心、心悸、头晕、意识障碍;昏迷,呼吸、心跳骤停。
局部损害:入口和出口;损伤范围外小内大;渗出较一般烧伤重;经常出现进行性坏死;关节屈面可出现“跳跃式”伤口。
3
治疗
现场急救:切断电源,心肺复苏。
液体复苏:补液量高于一般烧伤;碱化尿液;利尿。
早期清创,注意切开减张,包括筋膜切开减压。
早期全身应用较大剂量抗生素。
注射破伤风抗***。

电烧伤
Electrical burns may show erythema and bullae from the heat of arcing current or may be non-descript with severe internal damage between the points of contact and exit of the current.

电烧伤
The painful truth :
This person lost the use of 3 fingers, which took over 7 months to thing that worries Overgrow / Growfaq is the fact that most people don't understand, or believe that most of the time this beast kill's and does so without warning.
Most Overgrow members wouldn't want to be put into an electric chair, but will climb into one willingly while wiring a room, opening a ballast, building their own ballasts or other devices, you name it.
Electricity can and will kill you if you don't respect it!

二、化学烧伤
特点:某些化学物质接触人体后,除立即损伤外, 还可继续侵入或被吸收,导致进行性局部损害或全身性中毒。
一般处理原则:大量清水冲洗,大量补液,利尿,深度烧伤早期清创植皮,急救时不用中和剂。化学毒物致伤者选用解毒剂或对抗剂。
9
强酸(硫酸、盐酸、***)
组织蛋白凝固坏死,组织脱水;
无水疱,皮革样成痂,不向深部侵蚀,脱痂时间延缓;
急救时大量清水冲洗后按一般烧伤处理。
酸烧伤
