研究概览
简要总结
To compare renal function (51Cr-EDTA clearance) 48 hours post open-heart surgery (coronary bypass or valve surgery) in patients with impaired renal function after randomization to either nifedipine infusion at start of surgery and the following 24 hours or placebo (0.9% saline infusion). Study hypothesis is that nifedipine has a prophylactic effect on decline in renal function.

结局指标
主要结局
Primary efficacy endpoint is change in renal function, evaluated by 51Cr-EDTA clearance between 24 hours pre open-heart surgery and 48 hours post open-heart surgery. Sample size is 20, ten in each group.
次要结局
- Change in renal function after open-heart surgery, as measured by cimetidine refined serum creatinine clearance with measurements preoperatively and 2-6 hours, 20-24 hours and 44-48 hours postoperatively. Need for dialysis post-operatively.
