Primary Outcome Measures:
  • Rise in creatinine above baseline [ Time Frame: 7 days postoperatively ]

Secondary Outcome Measures:
  • Creatinine increase >25% or =/> 0.5 mg/dl above baseline [ Time Frame: Postoperative days 5, 7 and 30 ]
  • Length of stay in the ICU and the hospital
  • Operative mortality [ Time Frame: 30-day ]

Enrollment: 102
Study Start Date: April 2003
Study Completion Date: November 2006
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
