创伤患者围术期极易出现低体温,是创伤病人并发症之一。据报道,如果创伤患者低温持续4h以上,死亡率可达40%,体温降至32℃以下,死亡率为100%[1]。因此,通过被动与主动保温措施,防止患者发生低体温,维持恒定的核心体温极为重要。现就创伤患者围术期低体温的原因、危害及防 Perioperative trauma patients prone to hypothermia, is one of the complications of trauma patients. According to reports, if the trauma patients cryogenic persist for more than 4h, the mortality rate of up to 40%, body temperature dropped to below 32 ℃, the mortality rate was 100% [1]. Therefore, by passive and active insulation measures to prevent patients with hypothermia, to maintain a constant core body temperature is extremely important. Now perioperative trauma patients hypothermia causes, hazards and prevention
