Zealley I, et al. - This study was implemented to explore the link, if any, between the timing of contrast media (CM) exposure during the immediate perioperative period and risk of post-operative acute kidney injury (AKI). As per findings, avoiding CM administration, which in turn limits computed tomography (CT) scan quality, was not appeared to be required for patients who have either just had or are soon to undergo general surgical procedures and contrast-enhanced CT scans may benefit these patients without increasing their risk of perioperative AKI.
