寒冷损伤概述

来源:华人健康网 | 发布时间:2010-10-30 09:39:11 | www.chinesejk.com

  由寒冷引起小血管,细胞,神经和皮肤的结构和功能障碍所致的损伤.

  滥用药物,衰竭,饥饿,脱水,低氧,心血管功能受损以及与潮湿物或金属接触均可增加对寒冷损伤的易感性.老年,幼年和酒精中毒者特别危险.

  预防措施虽然很清楚,但常被忽略.即使天气不至造成寒冷损伤,穿多层保暖衣服,防潮和防风十分重要.遇到非常冷的气候时手套和袜子应尽可能保持干燥,应穿不影响循环的保暖靴.头部保暖至关重要,因30%的体热从头部散失.摄食足够的液体和食物有助于维持代谢性产热.警觉身体某些部位出现受凉麻木并立即给予温暖,可防止受损害.当人体发冷,发抖时,身体活动,穿保暖衣服和喝热饮料可防止体温过低.
