中暑不宜喝大量白开水

来源:[标签:来源] | 发布时间:2011-05-06 21:26:43 | www.chinesejk.com

  发现有人中暑后,迅速降低体温的同时需要及时补充丢失的水分。

  中暑后大量喝白开水,不仅会冲淡胃液,影响消化功能,还会引起反射性排汗亢进,使体内水分和盐分进一步大量流失,严重时可导致热痉挛,出现肌肉抽搐或肌肉痉挛性疼痛。

  正确的方法是让患者喝淡盐水,补充水分和电解质钠,并采用少量、多次的饮水方法,每次不超过300毫升为宜,每小时喝水量不能超过1升。

  配制淡盐水按500毫升水加5克盐的比例,可补充机体出汗的需要,同时也可防治电解质紊乱,因为人体大量排汗时,汗液带走了不少无机盐,如钠、钾、镁离子等。喝10℃左右的凉淡盐水,可达到迅速降温、解渴、缓解中暑的目的。
