随着放射显像技术尤其是冠状动脉介入的广泛开展,对比剂对肾功能的损害逐渐受到关注。对比剂性急性肾损害(contrast medium-induced acutekidney injury,CI-AKI)是指排除其他肾脏损害因素使用造影剂后3d内发生的急性肾功能损害。通常以48h内血肌酐比造影前基础水平上升25%,或是血肌酐上升44.2μmol/L为标准。最近出版的国外 With the widespread use of radiological imaging techniques, especially coronary intervention, the damage of contrast agents to renal function has drawn increasing attention. Contrast-induced acute kidney injury (CI-AKI) is defined as the acute renal impairment that occurs within 3 days after contrast media is excluded from other kidney damage agents. Usually within 48h serum creatinine than before basal level increased by 25%, or serum creatinine increased 44.2μmol / L as the standard. Recently published abroad
