【 摘 要 】

Objectives: There have been conflicting results on the clinical utility of furosemide in preventing contrast-induced nephropathy (CIN). This study aimed to elucidate the effect of additional furosemide treatment beyond saline hydration on CIN post radiologic procedures by a meta-analysis of randomized controlled trials (RCTs). Methods: The Medline, EMBASE, and Cochrane databases were systematically searched. Two reviewers independently determined the eligibility of studies that randomly assigned patients undergoing radiologic procedure to receive additional peri-procedural furosemide injection or intravenous saline hydration alone. Combined results were presented as risk ratios (RR) with 95% confidence intervals (CI) by random-effect models. Results: We identified 5 RCTs including 1330 patients. Of them 659 received peri-procedural furosemide injection in addition to saline hydration, and 671 only received intravenous saline hydration (the control). Relatively small total number of dialysis events and heart failure events were reported in the included studies (n = 18 across 5 trials, n = 24 across 3 trials, respectively). Compared to the control, additional furosemide treatment did not significantly increase the incidence of CIN (RR = 1.18; 95% CI, 0.50-2.78; P = 0.71) and the risk of dialysis (RR = 1.03; 95% CI, 0.41-2.57; P = 0.95) post radiologic procedure. Furthermore, furosemide treatment appeared to decrease the occurrence of heart failure (RR = 0.35; 95% CI, 0.14-0.88; P = 0.02). Conclusions: Peri-procedural furosemide treatment in addition to saline hydration did not provide significantly prophylactic effect on CIN after radiologic procedure. Nevertheless, the process seemed likely to decrease the risk of heart failure post saline hydration.
