  Purpose
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.

Condition Intervention
Acute Renal Failure Drug: Sodium bicarbonate plus saline Drug: Intravenous NAC plus saline Drug: NAC plus sodium bicarbonate plus saline Drug: Saline Drug: NAC plus saline

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

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

Arms Assigned Interventions
Active Comparator: Intravenous NAC plus saline
Acetylcysteine 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.
Drug: Intravenous NAC plus saline
Acetylcysteine (Flucistein 100 mg/ml, Neo Química, Brazil) was given via IV bolus at a rate of 150 mg/kg in 500 ml dextrose 5% over 60 min immediately before contrast exposure and followed by 50 mg/kg in 500 ml dextrose 5% during the contrast exposure and for 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.
Drug: NAC plus saline
Acetylcysteine 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.
Active Comparator: Sodium bicarbonate plus saline
Sodium 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.
