【摘要】 目的探讨肾血流搏动指数(PI)改变与体外循环手术(CPB)急性肾功能损害(AKI)的可能关系。方法对14例心脏病在实施体外循环心脏直视手术前、术后1、2、4、8、16、24h,运用彩色多普勒血流显像分别监测各时点肾主动脉、肾段动脉搏动指数,并同时检测肾功能尿素氮(Urea)、尿酸(UA)、肌酐(Crea),对所有数据进行统计分析。结果肾主动脉PI术后1、2、4、8、16h与术前相比明显增高,肾段动脉术后1、2、4、16hPI与术前相比明显增高,肾血流PI与肾功能指标Urea、UA、Crea呈正相关。结论体外循环术后肾主动脉、肾段动脉血流PI与Urea、UA、Crea存在相关性。更多还原

【Abstract】 Objective In this study,to explore the relationship between the renal blood flow PI,and the AKI was caused by CPB.Methods 14 cases with heart disease were accepted.The renal aorta and renal segmental artery PI of all cases were monitored by the CDFI at the preoperative and postoperative 1h,2h,4h,8h,16 h,24h.The renal blood urea nitrogen(Urea),uric acid(UA),creatinine(Crea),were detected at the same time.All datas for statistical analysis.Results The renal aorta PI was higher at the postoperative 1h,2h,4h,8h,16 hthan that at the preoperative.The renal segmental artery PI was higher at the postoperative1 h,2h,4h,16 hthan that at the preoperative.The renal blood flow PI was positively correlated with Urea,UA and Crea.Conclusion The renal aorta,renal segmental artery PI was positively correlated with Urea,UA and Crea after CPB.The PI may be seen as an evaluation index to assess AKI after CPB.更多还原
