Acetylcysteine in the Prevention of Renal Failure After Bypass Surgery

September 18, 2007 updated by: Minneapolis Veterans Affairs Medical Center

Single Center Randomized Clinical Trial of the Effects of Acetylcysteine in the Prevention of Postoperative Renal Failure

The purpose of this study is to determine if Acetylcysteine is effective in preventing renal failure associated with cardiac surgery

Detailed Description

Postoperative renal dysfunction is a predictor of significant morbidity and mortality among patients undergoing cardiac surgery. The mortality associated with coronary artery by-pass surgery increases from 2% to almost 19% in patients with renal failure and approaches 60% in patients who require hemodialysis. Patients with preoperative renal dysfunction referred for coronary artery by pass surgery have an extraordinarily high risk of requiring postoperative dialysis. For example, among those patients with preoperative creatinine >2.5 mg/dL, almost 50% require hemodialysis.

Comparison: N-Acetylcysteine is superior to placebo in preventing renal failure after cardiac surgery
