体温在35℃以下的状态谓之低体温。常见于冬季登山、水上遇难、饮酒、药物中毒以及外伤等。一般认为直肠温30℃为复苏的界限。笔者救治过伴有心跳停止的浸渍低体温(21℃)病例,而且未留后遗症。因此对于所有低体温病例都应积极采取复苏方法。当然,低体温病例不能全部复苏,其预后和诸多因素密切相关(见表)。脑血管障碍、缺血性心疾病及合并头部外伤者预后不良。预后同年龄关系似乎不大;药物和酒精中毒等可使致命的心室纤颤增加。此外,冬季溺水的浸渍低体温症同在寒冷环境中放置的暴露低体温症不同,由于
Body temperature below 35 ℃ in the state that the low body temperature. Common in winter mountaineering, water killed, alcohol, drug poisoning and trauma. Rectal temperature is generally believed that 30 ℃ for the recovery of the boundaries. The author treated with a heartbeat infusion of hypothermia (21 ℃) cases, but without leaving sequelae. So for all cases of hypothermia should be taken actively recovery method. Of course, hypothermia cases can not be fully recovered, the prognosis and many factors are closely related (see table). Cerebral vascular disorders, ischemic heart disease and head trauma combined with poor prognosis. The prognosis does not seem to be related to the same age; drugs and alcoholism can make fatal increases in ventricular fibrillation. In addition, immersion hypothermia in winter drowning is different from exposure to hypothermia in cold conditions due to
