Prevention of Acute Kidney Injury in Cardiac Surgery Patients
In Brief
A Phase 2 clinical trial evaluating 0.9% Sodium Chloride (Placebo) and Sodium Bicarbonate for Kidney Injury. Completed, enrolled 92 participants across 1 site.
Detailed Summary
Acute kidney injury (AKI) has no uniform criteria, but is commonly defined as an increase in serum creatinine concentration by at least 25% from baseline. It occurs in 30% of patients following cardiac surgery, and at least 50% of patients with underlying renal insufficiency. Patients who have a reduced creatinine clearance pre-operatively are at the greatest risk of developing post-operative AKI. The purpose of the current study is to determine if intravenous hydration with either isotonic saline or sodium bicarbonate 150 mEq/L is effective at preventing post-operative AKI in patients with baseline kidney insufficiency and who are undergoing cardiac surgery using cardiopulmonary bypass. The study hypothesis is that an infusion of sodium bicarbonate 150 mEq/L will be more effective than isotonic saline in reducing the incidence of post-operative AKI in cardiac surgery patients with a preoperative glomerular filtration rate (GFR) less than 60 ml/min/1.73m2.

Timeline
Interventions
0.9% Sodium Chloride (placebo) will infuse at 3 ml/kg/hr for one hour pre-operatively until the patient is started on cardiopulmonary bypass. Then the infusion will be reduced to 1 ml/kg/hr throughout cardiopulmonary bypass and for six hours following cardiopulmonary bypass.
Group two will receive sodium bicarbonate 150mEq in 850ml of a 5% dextrose solution at 3 ml/kg/hr for one hour pre-operatively until the patient is started on cardiopulmonary bypass. Then the infusion will be reduced to 1 ml/kg/hr throughout cardiopulmonary bypass and for six hours following cardiopulmonary bypass.
