BACKGROUND: Iodinated contrast media (CM) used in angiography and computed tomography (CT) scans is an important cause of acute kidney injury (AKI) in hospitalized patients undergoing surgery. Contrast-induced nephropathy leads to AKI soon after CM administration. The aim of the study was to determine whether the timing of contrast media exposure related to diagnostic imaging during the immediate perioperative period influences the risk of post-operative AKI.
METHODS: All patients aged 18 years or above who underwent diagnostic imaging within 7 days of non-cardiac surgery between 1 January 2003 and 31 December 2013 in the Tayside region of Scotland, UK were included in the analysis. The primary outcome of AKI was defined using the Kidney Disease: Improving Global Outcomes creatinine-based criteria. Multiple logistic regressions were performed to identify predictors for AKI.
RESULTS: Of 9300 patients, 6224 were exposed to CM in the immediate perioperative period and 3076 were not. Post-operative AKI occurred in 678 (10.9%) of the 6224 patients who were exposed to CM. On multiple logistic regression, independent predictors of post-operative AKI were increasing age, male gender, lower baseline renal function and treatment with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. Timing of CM exposure did not affect risk of developing AKI, odds ratio 0.972 (95% confidence interval 0.935-1.010), P = 0.146.
CONCLUSIONS: For patients who have either just had or are soon to undergo general surgical procedures there appears to be no need to limit CT scan quality by avoiding the administration of CM. These patients may benefit from the increased diagnostic utility of contrast-enhanced CT scans without increasing their risk of perioperative AKI.
