摘要
目的评估RIFLE分级定义的连续性肾脏替代治疗(continuous renal replacement therapy,CRRT)治疗时机对急性肾损伤(acute kidney injury,AKI)患者预后的影响。方法选取符合AKI诊断标准并行CRRT治疗的患者87例,RIFLE危险期定义为早期,损伤期、衰竭期定义为晚期,早期透析组31例,晚期透析组56例。记录一般临床资料,观察透析开始后28天、90天死亡率、肾功能恢复率。结果①早期透析组、晚期透析组28天、90天死亡率比较分别为64.52%比57.14%、67.74%比66.07%,P>0.05。Kaplan-Meier生存曲线提示2组生存时间无显著差别(P=0.67)。2组透析患者28天、90天死亡风险无明显差别,28天RR=0.724(P=0.489),90天RR=0.921(P=0.864)。②早期透析组、晚期透析组28天、90天肾功能恢复率比较分别为38.70%比30.36%、38.70%比32.14%,P>0.05。2组透析患者28天、90天不能脱离透析的危险无显著差异,28天RR=1.449(P=0.430),90天RR=1.333(P=0.538)。③Cox多因素分析显示APACEII是AKI患者死亡的危险因素。结论 RIFLE分级作为AKI患者CRRT治疗时机,不能预测患者死亡率与肾功能恢复率。
Objective To evaluation the relationship between the initiation of continuous renal replacement therapy （CRRT） guided by RIFLE grading and clinical outcomes in critically ill patients with acute kidney injury （AKI）.Methods We recruited 87 AKI patients treated with CRRT in the period from 2010 to 2013.They were divided into early （RIFLE classified as risk,n=31） and late （RIFLE classified as injury or failure,n=56） initiation of CRRT by RIFLE criteria.Their demographic data and biochemistry parameters were collected.Clinical outcomes including mortality and renal function recovery were recorded.Results After the initiation of CRRT,the mortality rate at the 28th day was 64.52％ and 57.14％ in the early group and late group,respectively,and that at the 90th day was 67.74％ and 66.07％ in the early group and late group,respectively （P＞0.05）.Kaplan-Meier curve revealed that the survival estimates were similar between the two groups （P=0.67）.The relative death risks at the 28th and 90th days were also similar between the two groups （RR=0.724 and 0.921,respectively; P＞0.05）.Renal function recovery at the 28th day was 38.70％ and 30.36％ in the early group and late group,respectively,and that at the 90th day was 38.70％ and 32.14％ in the early group and late group,respectively （P＞0.05）.The relative risks for renal function recovery at the 28th and 90th days were also similar between the two groups （RR=1.449 at the 28th day,P=0.430; RR=1.333 at the 90th day,P=0.538）.Cox multivariate analyses revealed that APACHE Ⅱ score was the death risk factor for AKI patients.Conclusions RIFLE classification as the guide for the initiation of CRRT could not be used to predict the mortality at the 90th day and the renal function recovery in AKI patients.
