Brief Summary:
The increased risk for contrast-induced nephropathy (CIN) in patients with chronic kidney disease (CKD) undergoing coronary angiography (CAG) has been established. Current and historical data on CIN prevention strategies have shown wide variation with respect to the optimal type, route and timing of these therapies. We investigate the role for oral hydration and/or oral sodium bicarbonate administration compared to intravenous hydration and/or sodium bicarbonate in patients with CKD undergoing CAG.

Condition or disease Intervention/treatment Phase
Contrast Induced Nephropathy Other: Oral hydration Drug: Oral sodium bicarbonate Other: Intravenous Hydration Drug: Intravenous sodium bicarbonate Phase 4

Detailed Description:
This is a single center study randomizing patients with CKD undergoing CAG into 4 groups: 1) Intravenous normal saline, 2) Intravenous normal saline and intravenous bicarbonate, 3) oral hydration, and 4) oral hydration and oral bicarbonate. The primary endpoint was the occurrence of contrast-medium-induced nephropathy defined as greater than 25% increase in serum creatinine from baseline or an absolute increase of 0.5 mg/dL from baseline at 72 hours following exposure to radiocontrast. Secondary endpoints include the length of hospitalization and in-house mortality.

Arm Intervention/treatment
Active Comparator: Intravenous Hydration
Pretreatment with a 3 mL/kg bolus of intravenous normal saline solution (154 mEq/L) over 1 hour, immediately prior to contrast exposure followed by intravenous infusion of 1ml/kg per for 6 hours after the procedure.
 Other: Intravenous Hydration
Pretreatment with a 3 mL/kg bolus of intravenous normal saline solution (154 mEq/L) over 1 hour, immediately prior to contrast exposure followed by intravenous infusion of 1ml/kg per for 6 hours after the procedure.
Active Comparator: Intravenous hydration and sodium bicarbonate
Pretreatment with a 3 mL/kg bolus of intravenous sodium bicarbonate solution (154 mEq/L) over 1 hour, immediately prior to contrast exposure followed by intravenous infusion of 1 mL/kg for 6 hours after the procedure.
 Other: Intravenous Hydration
Pretreatment with a 3 mL/kg bolus of intravenous normal saline solution (154 mEq/L) over 1 hour, immediately prior to contrast exposure followed by intravenous infusion of 1ml/kg per for 6 hours after the procedure.

Drug: Intravenous sodium bicarbonate
Pretreatment with a 3 mL/kg bolus of intravenous sodium bicarbonate solution (154 mEq/L) over 1 hour, immediately prior to contrast exposure followed by intravenous infusion of 1 mL/kg for 6 hours after the procedure.
Active Comparator: Oral hydration
Oral hydration with 500 mL of water to be started 4 hours prior to contrast exposure and stopped 2 hours prior to procedure followed by oral hydration with 600 mL of water post procedure
 Other: Oral hydration
Oral hydration with 500 mL of water to be started 4 hours prior to contrast exposure and stopped 2 hours prior to procedure followed by oral hydration with 600 mL of water post procedure
Active Comparator: Oral hydration and oral sodium bicarbonate
Oral hydration with 500 mL of water to be started 4 hours prior to procedure and stopped 2 hours prior to contrast exposure, with the addition of 3.9 grams (46.4 mEq) of oral sodium bicarbonate to be given 20 minutes prior to contrast exposure followed by 1.95 grams (30.4 mEq) of oral sodium bicarbonate 2 hours and 4 hours after the initial dose
 Other: Oral hydration
Oral hydration with 500 mL of water to be started 4 hours prior to contrast exposure and stopped 2 hours prior to procedure followed by oral hydration with 600 mL of water post procedure

Drug: Oral sodium bicarbonate
Oral hydration with 500 mL of water to be started 4 hours prior to procedure and stopped 2 hours prior to contrast exposure, with the addition of 3.9 grams (46.4 mEq) of oral sodium bicarbonate to be given 20 minutes prior to contrast exposure followed by 1.95 grams (30.4 mEq) of oral sodium bicarbonate 2 hours and 4 hours after the initial dose
