Recommendations for Use of IV Iodinated Contrast Media Updated
Radiologists and clinicians should weigh the relative benefits and risks of using IV contrast in patients with eGFRs less than 30 mL/min/1.73 m2, according to a consensus statement.
Contrast-Induced Nephropathy
Renal Outcomes Not Worsened by Omitting Hydration Prior to Contrast-Enhanced CT
Withholding prehydration with sodium bicarbonate from patients with CKD stage 3 undergoing nonemergent contrast-enhanced computed tomography does not compromise renal safety, a study found.
Data Support Group II Gadolinium-Based Contrast Use in Advanced Kidney Disease
The potential diagnostic harms of withholding group II gadolinium-based contrast agents may outweigh the risk of nephrogenic systemic fibrosis in advanced CKD patients, according to investigators.
Hepcidin May Enable Early Ruling Out of Contrast-Induced AKI
Serum hepcidin rises significantly as early as 4 and 8 hours after percutaneous coronary intervention.
Acute Kidney Injury Risk Lower With Ultra-Low Contrast Volume Use
Use of ultra-low contrast volume during percutaneous coronary intervention was associated with 32% decreased odds of acute kidney injury, investigators report.
Ultra-low Contrast Volume May Protect Kidneys in Advanced CKD
No patient had a 25% or greater rise in serum creatinine 48 hours after receiving a median 13 mL of contrast for diagnostic coronary angiography, with an additional 13 mL for percutaneous coronary intervention.
IV Sodium Bicarbonate Does Not Reduce AKI Risk After Angiography
Contrast-associated acute kidney injury occurred in 9.5% and 9.1% of patients receiving IV sodium bicarbonate and acetylcysteine, respectively, rates which did not differ significantly from the 8.3% rate among those receiving IV sodium chloride.
AKI More Likely After Intracoronary Versus IV Contrast Delivery
In a phase 3 trial, acute kidney injury developed in 13.2% of patients undergoing invasive coronary angiography compared with 5.6% of those undergoing computed tomography angiography.
AKI After Computed Tomography Not Tied to Contrast
AKI occurred with similar frequency among patients who did and did not receive contrast medium.
Post-PCI Acute Kidney Injury Not Linked to Contrast Use
Myocardial infarction patients who underwent percutaneous coronary intervention had an AKI rate similar to those who did not have the procedure.
