文摘目的分析急诊重症监护室(emergency intensive care unit, EICU)内行连续肾脏替代治疗(continuous renal replacement therapy, CRRT)的急性肾损伤(acute kidney injury, AKI)患者的预后危险因素。方法采用回顾性研究方法,收集2012年5月至2016年12月在上海交通大学医学院附属新华医院EICU住院并行CRRT治疗的138例AKI患者的临床资料。根据患者住院28 d的存活情况,分为死亡组(58例)和存活组(80例),采用多元logistic回归分析两组患者的临床资料,分析影响患者预后的危险因素。结果138例患者中有58例死亡,病死率为42.0%。与存活组相比,死亡组年龄更大,男性更多,入院时急性生理与慢性健康评分Ⅱ(acute physiology and chronic health evaluationⅡ,APACHEⅡ)和血乳酸值更高,既往有冠心病史以及使用机械通气和血管活性药物的比例更大,但入院时血清肌酐值较存活组低。多元logistic回归分析显示年龄(OR=1.064,95%CI:1.022~1.108,P=0.002)、APACHE Ⅱ评分(OR=1.127,95%CI:1.003~1.265,P=0.044)、机械通气(OR=7.432,95%CI:2.183~25.308,P=0.001)和使用血管活性药物(OR=24.558,95%CI:7.651~78.825,P<0.01)是影响EICU内需CRRT治疗的AKI患者预后的独立危险因素。结论高龄、高APACHE Ⅱ评分、行机械通气和使用血管活性药物是预测EICU内需CRRT治疗AKI患者的死亡危险因素。
