- Abstract
Objective: We investigated the effects of low-dose furosemide, administered with adequate hydration on contrast-induced nephropathy (CIN). Methods: A total of 859 patients scheduled to undergo coronary angiography or angioplasty were enrolled and randomly assigned to a furosemide treatment or control group. All patients received supplemental hydration. Immediately after surgery, patients in the furosemide group received intravenous furosemide injection (20 mg); those in the control group received no treatment. Total fluid intake and urine output were recorded. Pre- and postsurgical changes in serum creatinine levels (SCr), glomerular filtration rate (GFR) and creatinine clearance rate (CCr) were assessed, and the incidence of CIN was also evaluated between the two groups. Logistic regression analysis was used to study risk factors for CIN. Results: General baseline conditions were similar between the two groups. Patients who received furosemide had significantly less increase in SCr and a more marked increase in GFR and CCr than those who did not. The incidence of CIN was significantly higher in the control group. Logistic regression analysis revealed that female gender and angiotensin-converting enzyme inhibitor were risk factors for CIN, whereas furosemide acted as a protective agent. Conclusions: With full hydration, small doses of furosemide can reduce CIN better than hydration alone. Copyright © 2013 S. Karger AG, Basel
