目的探讨急诊科重症监护病房(ICU)患者死亡的高危因素。方法选取我院急诊科重症监护病房收治的200例危重症患者为研究对象，按照临床治疗结果分为生存组(155例)和死亡组(45例)。统计分析两组患者性别、年龄、Gcs评分、APACHEⅡ评分、白蛋白、c-反应蛋白、基础性疾病、死亡原因及医院感染等因素的差异。结果死亡组年龄明显大于生存组，死亡组基础性疾病明显多于生存组，死亡组Gcs评分明显低于生存组，死亡组APACHEⅡ评分明显高于生存组，差异具有统计学意义(<0.05)；死亡组患者血清白蛋白水平明显低于生存组，死亡组c-反应蛋白水平明显高于生存组，死亡组医院感染率明显高于生存组，差异具有统计学意义(<0.05)；呼吸衰竭和多脏器功能衰竭是死亡组患者死亡的主要原因。结论明确重症监护病房患者死亡的高危因素，有利于对患者的病情进行有效评估，采取积极合理的干预措施，进而降低患者的死亡率。“,”Objective To investigate the death risk factors analysis of ICU patients in our hospital emergency department.Methods 220 cases of critical y il patients in our hospital emergency department ICU were selected as research object,and were divided into survival group (155 cases)and death group (45 cases)according to clinical treatment.The dif erences on sex,age,Gcs score,APACHEⅡscore,albumin, c-reactive protein,basic disease,death reason,and hospital infection of two groups were statistical analyzed.Results The age of death group was significantly higher than survival group,basic disease of death group was significantly moer than survival group,Gcs score of death group was significantly lower than survival group,APACHEⅡscore of death group was significantly higher than survival group,the dif erences were statistical y significant ( <0.05);serum albumin levels of death group was significantly lower than survival group,c-reactive protein levels of death group was significantly higher than survival group,hospital infection of death group was significantly higher than survival group,the dif erences were statistical y significant ( <0.05);Respiratory failure and multiple organ failure were the factors for death. Conclusion Understanding the death risk factors of ICU patients,can ef ectively assess patients conditions and take positive and rational interventions to reduce the death rate.
