急性脑梗死早期发热危险因素的回归分析

Analysis of risk factors of hyperthermia in the early period of an acute cerebral infarction

目的探讨急性脑梗死早期发热的相关因素。方法回顾性分析了2003年1月至2004年12月收治的,经CT或MRI诊断的急性脑梗死患者共299例,对意识障碍、球麻痹、慢性支气管炎肺气肿、房颤、多发性脑卒中、糖尿病和慢性心衰七个危险因素与发热的相关性进行Logistic回归分析。结果感染患者共71例,急性脑梗死发热率为23.7%;感染最常见的是肺炎(感染率为18.4%)。意识障碍、房颤和心衰与急性脑梗死早期发热相关。结论急性脑梗死早期发热可加重脑损伤和预后不良,早期感染是导致发热的主要原因。意识障碍、房颤和心衰等是早期发热的危险因素。

Objective To investigate the risk factors of hyperthermia in early period pf an acute cerebral infarction. Methods 299 patients admitted to hospital from January 2003 to December 2004 with a djagnosis of cerebral infartion by CT or MR l,were retrospectively studied. The risks of hyperthermia in the early period for stroke, such as admission conscious level, bulbar palsy, emphysema, atrial fibrillation, multi-cerebral infarction, diabetes mellitus and chronic heart failure were analyzed,Logistic regression analysis was used to determine the factors that were associated with hyperthermia in the early period of stroke. Results 71 patients had fever in early period of an acute cerebral infarction（23.7 % ）. The most common infection was pneumonia（ 18, 4 %）, The analysis showed that the admission conscious level and atrial fibrillation were the risks of early hyperthermia of an acute cerebral infarctioN： Conclusion Admission conscious level （subconscious or unconscious/coma） and atrial fibrillation amd chropic heart failure are independent risk factors for development of early hyperthermia for acute stroke,
