Objective: A meta-analysis was performed to evaluate the effect of furosemide combined with hydration therapy on the incidence and prognosis of contrast-induced acute kidney injury (CI-AKI) in patients after coronary intervention.
Materials and methods: Through the PubMed, EMBASE, Cochrane Library and Web of Science databases, all relevant literature from database establishment until October 1, 2020, was retrieved and screened. Quality evaluation was performed using the risk of bias evaluation tool recommended by the Cochrane Collaboration network, data extraction was performed based on pre-selected effect indicators, and statistics were calculated using Review Manager 5.3 analysis software.
Results: A total of 2084 patients in 9 studies were included in the meta-analysis. The results showed that furosemide combined with hydrotherapy had no effect on the incidence of CI-AKI (OR = 0.85, 95% CI [0.46, 1.60], p = 0.62) and can significantly decrease the incidence of major adverse cardiovascular events (MACEs) (OR = 0.43, 95% CI [0.27, 0.67], p = 0.0003) and mortality (OR = 0.24, 95% CI [0.08, 0.79], p = 0.02) in patients. However, it had no significant impact on the need for postoperative dialysis treatment, postoperative creatinine level or length of hospital stay.
Conclusions: Furosemide combined with hydration therapy has no significant effect on the incidence of CI-AKI in patients after coronary intervention but can reduce the incidence of MACEs and mortality, thereby providing clinical benefits.
