摘要
目的:探讨彩色多普勒超声(CDFI)定量分析技术对重症感染患者急性肾损伤(AKI)的诊断价值。方法:选取98例重症感染患者为研究对象,依据是否发生AKI分为AKI组(n=45)和非AKI组(n=53)。比较两组患者肾长径、肾横径、肾实质厚度、收缩期峰值血流速度(PS)、舒张末期血流速度(ED)、时间平均流速(TAV)、搏动指数(PI)、阻力指数(RI)、收缩期与舒张期流速比值(S/D)及血肌酐(Scr)水平;采用ROC曲线评估Scr和CDFI参数对AKI的诊断价值。结果:AKI组肾长径、肾横径、肾实质厚度和非AKI组比较,差异无统计学意义(P>0.05)。AKI组PS、ED、TAV低于非AKI组(P<0.05),PI、RI、S/D及Scr水平高于非AKI组(P<0.05)。ROC曲线分析显示,Scr的AUC值为0.764,CDFI参数的AUC值为0.889。结论:CDFI定量分析技术在重症感染患者AKI诊断中有较高应用价值,可为早期诊断提供新思路。
Objective:To analyze the value of color Doppler ultrasound(CDFI)quantitative analysis in the diagnosis of acute kidney injury(AKI)in patients with severe infection.Methods:A total of 98 patients with severe infection were selected as the research subjects,and were divided into AKI group(n=45)and non-AKI group(n=53)according to the incidence of AKI.Renal length diameter,renal transverse diameter,renal parenchymal thickness,systolic peak flow velocity(PS),end-diastolic flow velocity(ED),time mean flow velocity(TAV),pulsation index(PI),resistance index(RI),systolic to diastolic flow velocity ratio(S/D)and serum creatinine(Scr)level were compared between the two groups.ROC curve was used to evaluate the diagnostic value of serum creatinine and color Doppler ultrasonography parameters in acute kidney injury.Results:There were no significant differences in renal length diameter,transverse diameter and parenchymal thickness between AKI group and non-AKI group(P>0.05).The PS,ED and TAV in AKI group were significantly lower than those in non-AKI group(P<0.05).The PI,RI,S/D and Scr level were significantly higher than those in non-AKI group(P<0.05).ROC curve analysis showed that the AUC value of Scr was 0.764,and the AUC value of CDFI parameters was 0.889.Conclusion:CDFI quantitative analysis technique has a high application value in the diagnosis of AKI in patients with severe infection,and can provide a new idea for the early diagnosis and clinical practice of AKI.
