Hypothermia Therapy in Pediatric Cardiac Intensive Care Unit for Suspected for Brain Injury (Coolheart)
Congenital Heart Defects, Brain Ischemia, Hypoxia Brain
About this trial
This is an interventional treatment trial for Congenital Heart Defects focused on measuring Congenital Heart Defects, Hypoxic Ischemic Brain Injury, Hypothermia Therapy, Pediatrics
Eligibility Criteria
Inclusion Criteria:
- Every child entering the PCICU, age < 7 years
- The child will enter arm 1 or 2 if he underwent the event described in section 3.
Hypoxic ischemic event that would render hypothermia treatment is defined as
- During the hospitalization in the PCICU before or after the surgery:
Resuscitation comprised of chest compressions for more than 2 minutes, and the first blood tests immediately after the resuscitation show a serum lactate level of more than 90 mg/dl OR Resuscitation comprised of chest compressions for more than 2 minutes, and the first blood tests immediately after the resuscitation shows a serum lactate level of more than 40 mg/dl and a blood pH level of less than 7.1
- During the surgery Near infra red spectroscopy lower than 40 for more than 5 minutes AND Serum lactate levels of more than 90 mg/dl during the event OR The patient is re-connected to cardio-pulmonary bypass machine as a result of the event
- Initiation of hypothermia treatment within 6 hours following the hypoxic ischemic event defined in section 3.
Exclusion criteria
- Suspected hypoxic ischemic event as described in the Inclusion Criteria in the 2 weeks prior to the PCICU admission
- Prolonged low cerebral perfusion before the PCICU admission, with 3 repeated tests in 1 hour of lactate level higher than 40 mg/dl and pH lower than 7.1
- Rejection criteria
- A second resuscitation after the hypoxic ischemic event and before a brain MRI is done

Arm 3
Active Comparator
Placebo Comparator
No Intervention
Whole body hypothermia
Whole body normothermia
Control
Children that had an event suspected for hypoxic ischemic brain injury, according to the inclusion criteria, will be randomly allocated for whole body hypothermia therapy. Treatment will be initiated within 6 hours of the event, the child will be dressed with a cooling suit and their temperature will be monitored. Whole body hypothermia will be to 33 +/- 1 °C . Treatment period will be 48 hours with 24 hours warming up period.
Children that had an event suspected for hypoxic ischemic brain injury, according to the inclusion criteria, will be randomly allocated for normothermia therapy. Treatment will be initiated within 6 hours of the event, the child will be dressed with a cooling suit and their temperature will be monitored. Cooling will be to 36-37 °C . Treatment period will be 72 hrs.
A group of children that underwent a cardiac surgery and was not suspected to have an hypoxic ischemic brain injury. This group will be undergo the similar biomarkers collection as arm 1 and 2. The information will be used to measure the change in biomarkers between surgeries with no HII to those in arm 1+2.
