Intravenous High Dose NAC and Sodium Bicarbonate for the Prevention of Contrast-induced Acute Injury

Not Applicable
Completed
Conditions
Acute Renal Failure
Interventions
Drug: Intravenous NAC plus saline
Drug: Sodium bicarbonate plus saline
Drug: Saline
Registration Number
NCT01612013
Lead Sponsor
Federal University of São Paulo
Brief Summary

Contrast-induced acute kidney injury is a common cause of acquired in-hospital renal insufficiency and is associated with prolonged hospitalization and unfavorable early and late outcomes. The investigators sought to compare 4 different strategies (intravenous high-dose of N-acetylcysteine, sodium bicarbonate, the combination of both, and saline alone) in the prevention of contrast-induced acute kidney injury in patients undergoing coronary angiography using high-osmolar contrast media defined by creatinine and cystatin C serum levels.

NAC plus sodium bicarbonate plus salineNAC plus sodium bicarbonate plus salineAcetylcysteine was given intravenous at a rate of 150 mg/kg over 60 min before contrast exposure and followed by 50 mg/kg during and for 6 hours after the procedure. Sodium bicarbonate solution (150 mEq/L of sodium) was given in bolus began 60 min before contrast administration at 3.5 ml/Kg/h, decreased to 1.18 ml/Kg/h during and for the next 6 hours of the procedure. Saline was given intravenous at a rate of 1 ml/Kg/h over 60 min prior to the start of contrast administration and followed at the same rate during and for the next 6 hours after the procedure.
Intravenous NAC plus salineNAC plus salineAcetylcysteine was given via intravenous bolus at a rate of 150 mg/kg over 60 min immediately before contrast exposure and followed by 50 mg/kg during and for 6 hours after the procedure. Saline (0.9 percent) was given intravenous at a rate of 1 ml/Kg/h over 60 min prior and followed at the same rate during and for the next 6 hours the procedure.

Sodium bicarbonate plus salineSodium bicarbonate plus salineSodium bicarbonate solution (Sodium bicarbonate 8.4%, Equiplex, Brazil) was given by adding fifteen ampoules of sodium bicarbonate (150 mEq of sodium) to 1 L of 5% dextrose. Infusion in bolus began 60 min prior to the start of contrast administration at 3.5 ml/Kg/h, decreased to 1.18 ml/Kg/h during the contrast exposure and for the next 6 hours after the procedure. Saline (0.9 percent) was given IV at a rate of 1 ml/Kg/h over 60 min prior to the start of contrast administration and followed at the same rate during and for the next 6 hours after the procedure.

Primary Outcome Measures
NameTimeMethod
The development of contrast-induced acute kidney injury based either on the creatinine and/or Cystatin C increase between day 0 and 72 hours.72 hours

The primary end point of the study was the development of contrast-induced acute kidney injury based either on the creatinine and/or Cystatin C increase between day 0 (when contrast media was administered) and 72 hours (creatinine; Cystatin C increase ≥ 0.3 mg/dL increase and/or 10% increase, respectively within 72 hours after contrast media administration).

Secondary Outcome Measures
NameTimeMethod
The secondary end point was development of CI-AKI in a subgroup of high-risk patients, including patients with diabetes mellitus and those with pre-existent kidney disease defined as calculated creatinine clearance < 60 ml/min/1.73m2.72 hours
