[目的]分析重症监护病房(ICU)获得性肺炎患者预后的危险因素.[方法]回顾性分析116例确诊为 ICU 获得性肺炎患者的临床资料,根据患者住院期间是否死亡分为生存组和死亡组,对影响预后因素进行统计学分析.[结果]两组患者性别、年龄、体重指数(BMI)、基础疾病评分、GCS 评分、建立人工气道、机械通气、血小板计数(PLT )水平、尿素氮水平(BUN)水平、总胆红素水平(TBIL)水平、血浆白蛋白水平(ALB)等比较无统计学意义( P >0.05),ICU 住院史、急性生理和慢性健康评分(Apache Ⅱ评分)、序贯性器官功能衰竭评分(SOFA 评分)、使用血管活性药物、血糖等方面比较有统计学意义( P 0 .05) .There were significant differences in the history of hospitalization in ICU ,acute physiolo‐gy and chronic health evaluation score (APACHE Ⅱ score) ,sequential organ failure assessment score (SOFA score) ,the usage of vasoactive agent and blood glucose between two groups ( P < 0 .05) .Logistic regression analysis showed that the history of hospitalization in ICU and circulation support were the main risk factor of the death of ICU acquired pneumonia .[Conclusion] The higher the score of illness severity and hyperglycemia admitted in ICU may be the risk factors of the prognosis of patients with ICU acquired pneumonia .But the previous history of hospitalization in ICU and complicated shock are the independent risk factor of the death of patients with ICU acquired pneumonia .
