N-Acetylcysteine in Neonatal Congenital Heart Surgery (INACT Study)

• Status: Completed
• Trial end date: 2008-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to determine whether intravenous N-acetylcysteine (also known as Acetadote), an antioxidant medication that has been used for years to treat Tylenol overdose, helps prevent heart dysfunction in the early postoperative period following congenital heart surgery. Children undergoing major heart surgery, such as the arterial switch operation, routinely develop temporary heart dysfunction in the first 12-24 hours after surgery. This heart dysfunction may be severe and contributes to an increased risk for death or prolonged hospitalization. Current standard treatments include intravenous medications such as dopamine, epinephrine, and vasopressin that support your child's blood pressure and heart function. Unfortunately, high doses of these medications have the potential to cause severe side effects including loss of fingers and toes, liver and kidney dysfunction, and heart rhythm abnormalities. Our goal is to find a way to reduce heart dysfunction after major heart surgery in order to promote a smoother postoperative period, and reduce the risks associated with heart operations in children.
