1、体外循环手术后急性肾损伤临床研究作者:高珺,张丽,张浩,吴岭,陈茂杰【摘要】目的观察体外循环(CPB)手术对肾功能的影响。方法回顾分析246例施行CPB心内直视手术后患者的临床资料、手术相关指标与肾功能相关指标。根据2005年急性肾脏损伤网络(AKIN)对于急性肾损伤(AKI)的定义,判断患者的发病情况,并比较AKI与非AKI患者的各项指标。采用简化的MDRD公式评估2组患者术前的评估肾小球滤过率(eGFR)。结果246例中,22例发生AKI,总发病率8.9%;Ⅰ、Ⅱ、Ⅲ期AKI分别为15例(6.1%)、5例(2.0%
2、)、2例(0.8%)。与非AKI患者的各项指标比较结果显示:AKI患者年龄偏大(P<0.05),而术前血压、血红蛋白、肾功能等指标的差异无统计学意义(P>0.05);eGFR明显低于非AKI患者(P<0.05);体外循环时间及升主动脉阻断时间明显较非AKI患者延长(P<0.05);术后24h内尿量较非AKI患者显著减少,而24h引流液量显著多于非AKI患者(P<0.05)。结论患者年龄大、CPB及升主动脉阻断时间长是CPB手术后发生AKI的不利因素。术前评估eGFR可能有助于发现高危人群,
