Cerebrum and Cardiac Protection With Allopurinol in Neonates With Critical Congenital Heart Disease Requiring Cardiac Surgery With Cardiopulmonary Bypass
Netherlands236 participantsStarted 2020-02-14
Plain-language summary
Neurodevelopmental impairment due to delayed brain development and brain injury is a fundamental problem in children with critical congenital heart disease (CCHD). Significant longterm motor-, cognitive-, and behavioral problems are the result of early postnatally and perioperatively induced brain injury. Allopurinol, a xanthine oxidase inhibitor, prevents the formation of toxic free oxygen radicals, thereby limiting hypoxia-reperfusion damage. Both animal and neonatal studies suggest that administration of allopurinol reduces hypoxic-ischemic brain injury, is cardioprotective, and safe. This study aims to evaluate the efficacy and safety of allopurinol administered early postnatally and perioperatively in children with a CCHD requiring cardiac surgery with cardiopulmonary bypass.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Neonates with a prenatally or postnatally confirmed diagnosis of CCHD requiring (anticipated) cardiac surgery with CPB within the first 4 weeks of life.
* Informed consent provided by both parents.
Exclusion Criteria:
* Inability to enroll the patient before the start of delivery in case of prenatal diagnosis, or 24 hours before surgery in case of postnatal diagnosis.
* Doubt whether the aortic arch anomaly before birth requires cardiac surgery with CPB in the neonatal period.
* Gestational age below 36 weeks and/or birth weight less than 2000 gram.
* Surgery not requiring cardiopulmonary bypass.
* Decision for "comfort care only".
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
