摘要
目的 探讨儿科重症加强治疗病房(PICU)脓毒症患儿发生急性肾损伤(AKI)的危险因素及其预后影响因素。方法 回顾性分析2015年5月至2018年5月安徽省儿童医院PICU脓毒症患儿的临床资料,根据入PICU 48 h内是否发生AKI 〔改善全球肾脏病预后组织(KDIGO)诊断标准〕将患儿分为AKI和非AKI组。比较两组患儿一般资料、生理学数据及临床转归等,采用Logistic回归分析脓毒症患儿发生AKI的危险因素,并对预后因素进行分析。结果 127例脓毒症患儿中有55例发生AKI,AKI发生率为43.3%;总体病死率为28.3%(36/127),其中AKI组病死率为41.8%(23/55),非AKI组为18.1%(13/72)。①与非AKI组比较,AKI组氧合指数、白蛋白、小儿危重病例评分(PCIS)、尿量均明显下降,胱抑素C、降钙素原(PCT)、凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、小儿多器官功能障碍评分(P-MODS)、机械通气比例、血管活性药物使用比例、休克比例、脓毒性休克比例、病死率均明显升高,而两组年龄、性别、平均动脉压(MAP)、白细胞计数(WBC)、C?-反应蛋白(CRP)差异无统计学意义。多因素Logistic回归分析显示,低血清白蛋白〔优势比(OR)=0.627,95%可信区间(95%CI)=0.495~0.794,P=0.000〕、高胱抑素C(OR=2.641,95%CI=1.157~6.032,P=0.021)是脓毒症患儿发生AKI的危险因素。②在脓毒症AKI患儿中,与存活组比较,死亡组机械通气比例、脓毒性休克比例、血管活性药物使用比例、72 h液体正平衡比例、6 h乳酸清除率<10%比例、AKI 3期患儿比例均明显升高。多因素Logistic回归分析显示,72 h液体正平衡(OR=8.542,95%CI=1.956~37.307,P=0.004)、6 h乳酸清除率<10%(OR=5.980,95%CI=1.393~25.676,P=0.016)是脓毒症AKI患儿死亡的危险因素。结论 脓毒症患儿应密切监测血清白蛋白和胱抑素C;及早发现并干预治疗液体正平衡及低乳酸清除率,可降低脓毒症AKI患儿病死率。
