Aminophylline to Prevent Acute Kidney Injury in Children After Cardiac Surgery (KIDPROAM)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01245595
Recruitment Status : Completed

Brief Summary:
Children with congenital heart defects often need cardiac surgery with cardiopulmonary bypass (the "heart-lung machine"). Approximately 35 to 50% of these children will have "acute kidney injury," or damage to the kidneys, after the procedure. We currently have few medications to prevent this kidney injury. The hypothesis of this study is that giving aminophylline after heart surgery can decrease the acute kidney injury.

Condition or disease Intervention/treatment Phase
Acute Kidney Injury Drug: Aminophylline Drug: Placebo Not Applicable

Detailed Description:
Patients are randomized to receive aminophylline or placebo for 72 hours, in a blinded fashion. Serum theophylline levels monitor for safety of aminophylline dose. Goal theophylline levels is 5-7 mcg/ml. Laboratory results will be faxed directly to the pharmacy who will adjust subsequent aminophylline dosing to maintain appropriate theophylline levels. Urine output and serum creatinine levels will be monitored to assess acute kidney injury. Serum Neutrophil Gelatinase Associated Lipocalin (NGAL) levels will also be monitored.
