To determine the incidence and mortality of hypothermia in trauma patients.
Retrospective review of patients admitted to the Surgical Intensive Care Unit (SICU) over 4 1/2 years. Hypothermia was defined as a temperature < 35 degrees C.
There were 7045 admissions to the SICU, of which 661 (9.4%) had a recorded temperature of < 35 degrees C. Over half (395) were trauma patients, with a mortality of 52.7%. The temperature ranged from 27.1 to 34.9 degrees C, with a mean for survivors of 34.0 degrees C and 33.1 degrees C for those that died. There was a significant difference in Apache II scores (16.6 vs 25.4) and Injury Severity Scores (26.1 vs 33.4) between survivors and non-survivors.
The incidence of hypothermia in trauma patients is significant and is independent of the month of admission. Mortality is high but there is no threshold below which mortality is assured. Unlike historical data, 13 patients survived temperatures < 32 degrees C.
确定创伤患者体温过低的发病率和死亡率。
对4年半内入住外科重症监护病房（SICU）的患者进行回顾性研究。体温过低定义为体温<35摄氏度。
共有7045例患者入住SICU，其中661例（9.4%）体温记录<35摄氏度。超过半数（395例）为创伤患者，死亡率为52.7%。体温范围为27.1至34.9摄氏度，幸存者的平均体温为34.0摄氏度，死亡者为33.1摄氏度。幸存者和非幸存者之间的急性生理与慢性健康状况评分系统II（Apache II）评分（16.6对25.4）和损伤严重程度评分（26.1对33.4）存在显著差异。
创伤患者体温过低的发病率较高，且与入院月份无关。死亡率很高，但不存在确保死亡的体温阈值。与历史数据不同，有13例患者体温<32摄氏度仍存活。
