急性脑血管病患者体温与死亡关系的研究

The study of relationship of admission body temperature and stroke mortality

目的 研究体温升高与急性脑血管病 (acutecerebraldisease ,ACVD)死亡之间的关系。方法 采用回顾性定群研究的方法 ,对 2 89例ACVD患者入院时体温与死亡之间的关系进行了研究 ,将体温分为低体温 (≤ 3 6.5℃ )、正常体温 ( >3 6.5℃而≤ 3 7.5℃ )、高体温 ( >3 7.5℃ )三组。采用Logistic回归和成比危险函数 (proportionalhazardsfunc tion)分析的方法对资料进行分析。结果 在脑梗死组中 ,入院时低体温者病死率低而高体温者病死率高。脑出血组也有类似的趋势。结论 入院时体温升高是病死率增高的一个独立的危险因素。

Objective To study the relationship between admission body temperature and stroke mortality.Methods A cohort of 289 patients with acute stroke were admitted to our hospital between 1997 and 2003.The relationship between admission body temperature and mortality in-hospital was evaluated.Body temperature on admission was classified as hypothermia(≤36.5℃),normothermia(>36.5℃ and ≤37.5℃),and hyperthermia(>37.5℃).Logistic regression and proportional hazards function analysis were performed after adjustment for clinical predictor of stroke outcome.Results In ischemic stroke,mortality was lower among patients with hypothermia and higher among patients with hyperthermia,so were the same results in hemorrhage stroke.Conclusion The hyperthermia at admission is a independent risk factor of stroke mortality.
