NCT00497328

Brief Summary

This is a randomised controlled trial to investigate the efficacy of preventive regimen of hydration with high dose oral N-acetylcysteine and intravenous sodium bicarbonate pretreatment in patients with stable advanced renal insufficiency (CKD stage 3 and 4:GFR 15-60ml/min/1.73m2 calculated by Modification of Diet in Renal Disease Study equation (MDRD formula)) undergoing elective percutaneous coronary intervention (PCI).

Outcome Measures

Primary Outcomes (1)

  • Development of contrast induced nephropathy (defined as >25% rise in baseline creatinine 48 hours post coronary intervention)

    48 hours

Secondary Outcomes (1)

  • • Maximum change in serum creatinine level • Difference in hospital stay between groups • Need for hemodialysis • mortality • Maximum change in GFR • Peak creatinine level

    30 days

Study Arms (3)

N-acetylcysteine Group (NAC)

OTHER

N-acetylcysteine Group (NAC) Intravenous infusion 154mEq/L of sodium chloride (0.9% normal saline) at a rate of 1mL/kg/hour from 12 hours before till 6 hours after cardiac catheterization Oral NAC 1200mg dissolve in 250ml of water twice a day the day before to the day after the procedure (total 6 doses)

Drug: N-acetylcysteine

Sodium Bicarbonate Group (SOB)

OTHER

Sodium Bicarbonate Group (SOB) Intravenous infusion154meq/L sodium bicarbonate in 5% dextrose in water at a rate of 3 mL/kg/hour for 1 hour immediately before radiocontrast injection. For patients weighing more than 110 kg, the initial fluid bolus and drip will be limited to those doses administered to a patient weighing 110 kg. Intravenous infusion154meq/L sodium bicarbonate in 5% dextrose in water at a rate of 1 mL/kg/hour during the contrast exposure and for 6 hours after the procedure

Drug: Sodium Bicarbonate

Combination Group (COM: NAC and SOB)

OTHER

Combination Group (COM: NAC and SOB) Intravenous infusion of 154 meq/l sodium bicarbonate at a rate of 3ml/kg/hour for 1 hour before cardiac catheterization and 1 ml/kg/hour till 6 hours after procedure Oral NAC 1200mg dissolve in 250ml of water twice a day the day before to the day after the procedure (total 6 doses). All patients will be monitored regularly for pulmonary congestion and hemodynamics compromise hourly after PCI for 6 hours and every 4 hour thereafter for 24 hours.

Drug: N-acetylcysteineDrug: Sodium Bicarbonate

  • Administration of sodium bicarbonate solution or NAC within 48 hours before the PCI.
  • Patient unable to give consent
  • Clinically vulnerable condition requiring continuous fluid therapy e.g. severe sepsis
  • Use of NSAID, aminoglycocide, cyclosporin, cysplatin within 48 hours prior to PCI and throughout the study duration
