NCT01359722

Brief Summary

The purpose of this study is to determine the possible effect nephroprotective of N-acetylcysteine in patients with chronic kidney disease undergoing elective coronary artery bypass grafting by serial evaluation of renal function and to evaluate whether treatment reduces cardiac mortality, cardiac events and Global mortality, if it interferes with oxidative stress and inflammation and the need for dialysis.

Study Arms (2)

N-Acetylcysteine

EXPERIMENTAL

N-acetylcysteine is administered at a dose of 150mg/kg in 500mL of saline EV in 1 hour followed by a dose of 50mg/kg in 500 mL of saline IV within 6 hours, beginning the infusion together to surgery.

Drug: N-acetylcysteine

Control

PLACEBO COMPARATOR

This group will receive only the infusion of saline in the same doses and infusion rate.

Drug: Control

Interventions

N-acetylcysteine is administered at a dose of 150mg/kg in 500mL of saline EV in 1 hour followed by a dose of 50mg/kg in 500 mL of saline IV within 6 hours, beginning the infusion together to surgery.

Also known as: Fluimucil
