Original Article



The aim of this study was to evaluate the efficacy of carperitide in maintaining renal function during intraoperative and postoperative management of patients with renal dysfunction undergoing elective cardiovascular surgery.


The subjects were 88 patients with a preoperative serum creatinine level ≥1.2 mg/dl who underwent elective cardiovascular surgery using cardiopulmonary bypass. They were prospectively divided into a group that received carperitide from the start of surgery (carperitide group, n = 44) and a group that was not given carperitide (control group, n = 44). Carperitide infusion was initiated at the beginning of surgery and was continued for ≥5 days, with the central dose being 0.02 g/kg/min. The primary endpoint was the serum creatinine level on postoperative day (POD) 3.


The serum creatinine levels on PODs 3, 4, and 7 were significantly lower, and creatinine clearance on PODs 2 and 3 was significantly higher in the carperitide group than in the controls. One patient in the control group and no patient in the carperitide group required continuous hemodiafiltration, but the difference was not statistically significant.


Continuous low-dose infusion of carperitide from the start of cardiovascular surgery maintained renal function in patients with preoperative renal dysfunction.
