摘要

使用新型低或等摩尔非离子碘造影剂时,造影后急性肾损伤(PC-AKI)的发生率很低。预防 PC-AKI 的唯一行之有效的方法是补水,最好是静脉补水,尽管口服补水也同样有效。在本文中,我们定义了 PC-AKI 及其风险因素,提出了预防方案,并回答了围绕预防方案产生的最常见疑问。我们还更新了造影剂检测前应遵循的禁食指南。一般来说,在注射碘化造影剂或钆之前不需要禁食固体食物,除非是需要专门研究上消化道和胆管的检查。即使在这些情况下,也不需要禁食透明液体,这对口腔水合和降低 PC-AKI 的发生率大有帮助。

Nephroprotection and iodinate contrast medias
The incidence of post-contrast acute kidney injury (PC-AKI) is low with the new low- or iso-osmolar non-ionic iodinated contrast agents. The only proven form of prophylaxis for PC-AKI is hydration, preferably intravenous, although oral hydration is equally effective. In this article we define PC-AKI and its risk factors, propose a prophylaxis protocol and respond to the most common doubts that arise around prophylaxis. We also update the fasting guidelines to be followed prior to contrast testing. In general, fasting of solids is not necessary before injecting iodinated contrast or gadolinium except in tests in which it is necessary to specifically study the upper digestive tract and bile duct. Even in these cases, fasting clear liquids is not required, which is of great help for oral hydration and for reducing the incidence of PC-AKI.
