脑出血患者发生急性肾损伤的危险因素及预后分析

    Incidence and mortality of acute kidney injury after cerebral hemorrhage in neurology care unit

    • 摘要: 目的 了解脑出血患者急性肾损伤(AKI)的发生情况、住院病死情况及其相关危险因素。方法 回顾性分析2015年1月-2016年5月于武汉大学中南医院住院的354例脑出血患者的临床资料,以Logistic回归方程分析脑出血患者发生AKI及住院病死情况相关的独立危险因素,描绘ROC曲线,评价各独立危险因素对于脑出血患者AKI的发生及住院病死的预测价值。结果 纳入354例脑出血患者AKI总发病率为35.3%,AKI 1期、2期、3期发病率分别为22.3%、5.1%、7.9%。脑出血患者总住院病死率为28.3%,与非AKI组相比,AKI组患者的住院病死率显著增高(49.6%vs. 7.0%,P<0.01),AKI 1期、2期、3期患者住院病死率分别为39.2%,55.6%,75.0%。Logistic回归结果提示,使用利尿剂(OR=1.796)、使用机械通气(OR=1.728)、高急性生理与慢性健康状况评分(APACHEⅡ评分)(OR=1.153)是脑出血患者发生AKI的独立危险因素。发生AKI (OR=5.452)、贫血(OR=2.786)、高龄(OR=1.025)、高APACHEⅡ评分(OR=1.198)是脑出血患者住院病死的独立危险因素。APACHEⅡ评分预测脑出血患者AKI的发生及住院病死均具有良好的准确性(AUC分别为0.802,0.864,均P<0.01)。结论 AKI是脑出血患者常见的并发症,病死率高。重视AKI的早期筛查,尽早干预,是降低脑出血患者住院病死率有效措施。

       

      Abstract: Objective To explore the incidence and mortality of acute kidney injury (AKI) in neurology care unit (NCU) among cerebral hemorrhage patients, and to determine the risk factors of the incidence of AKI and the mortality of cerebral hemorrhage patients in NCU. Methods The clinical data of 354 cerebral hemorrhage patients in NCU from January 2015 to May 2016 at Zhongnan hospital of Wuhan University were collected retrospectively. Logistic regression was done to analyze the risk factors of the incidence of AKI and the mortality of cerebral hemorrhage patients in NCU, and then the receiver operating characteristic (ROC) curve was used to evaluate the predictive value of these risk factors. Results AKI accounted for 35.3% in NCU among cerebral hemorrhage patients. The incidence of AKI with AKI stage 1, 2, 3 among patients was 22.3%, 5.1% and 7.9% respectively. The total mortality of cerebral hemorrhage patients in NCU was 28.3%. The hospital mortality of non-AKI patients in the NCU was 7.0%, lower than 49.6% of AKI patients (P<0.01). The mortality of AKI with AKI stage 1, 2, 3 among patients was 39.2%, 55.6% and 75.0% respectively. Logistic regression suggested that hydragogue (OR=1.796), mechanical ventilation (OR=1.728), and APACHEⅡ scores (OR=1.153) were the independent risk factors of AKI. AKI (OR=5.452), anemia (OR=2.786), age (OR=1.025), and APACHEⅡ scores (OR=1.198) were the independent risk factors of mortality. For AKI and NCU mortality, APACHEⅡ scores had the good correctness of prediction. Conclusions AKI is a common complication among cerebral hemorrhage patients in NCU, and can significantly increase NCU mortality. We should take early detection for AKI seriously and make early prevention, which might be effective to decrease NCU hospital mortality.
