摘要 目的明确接受静脉内对比剂增强CT检查的高危病人,应用等渗对比剂相对于低渗对比剂对肾功能[血浆肌酐(SCr)与肾小球滤过率(GFR)]的影响。方法研究符合HIPAA要求,由医学伦理委员会批准并有知情同意书。117例(男83例,女34例;年龄18~86岁,平均64.3岁)肾功能低下的病人接受了对比剂增强CT检查,使用等渗碘克沙醇(n=61)或低渗的碘普罗胺(n=56)。CT检查后3d内检测SCr的增高与GFR的下降,并在30d与90d后随访,记录病人的结果。SCr增高标准:≥0.5mg/dL(44.2umol/L,25%)或≥1.0mg/dL(88.4umol/L,50%);GFR下降标准:≥5mL/min。
