Details and patient eligibility

About

The advances in cardiac surgery and anesthesia for pediatric patients planned for repair of congenital heart disease encourage us to discuss problems that occur during this surgery especially during Cardiopulmonary Bypass (CPB). Cardiopulmonary Bypass induces a damaging systemic inflammatory response, in addition to a myocardial ischemia-reperfusion injury (IRI) as a result of cessation and re-initiation of coronary artery circulation

Full description

After approval of the local ethics committee of Assiut University and obtaining written informed consent from parents or guardians of all patients, 60 patients with congenital heart disease will be included. Patients will be randomly allocated into three groups

Enrollment

87 patients

Ages

2 to 6 years old
