Brief summary
The aim of this study is to examine the effect of combining melatonin to whole body cooling on the brain injury and outcome of neonates following perinatal asphyxia.
Detailed description
This is a prospective study on 30 neonates with moderate to moderately to severe hypoxic ischemic encephalopathy (HIE) . HIE infants are randomized into two groups: Whole body cooling group (N = 15; receive 72 hours of whole body hypothermia) and melatonin/ hypothermia group (N = 15; receive hypothermia and 5 daily enteral doses of melatonin 10 mg/kg). Serum melatonin, plasma superoxide dismutase (SOD),and serum nitric oxide (NO) are measured at enrollment and after 2 weeks for the two HIE groups. The HIE groups underwent electroencephalography at enrollment and at 2 to 3 weeks. Brain MRI was performed after 2 weeks of life. Neurologic evaluations and Denver Developmental Screening Test II assessments were performed at 6 months. A group of healthy newborns will be used as a control for baseline labs.
Interventions
Melatonin is administered to the melatonin/hypothermia group (n=15) in a dose of 10 mg/kg daily for a total of 5 doses starting immediately at enrollment. Melatonin tablets (1 or 3 mg/tablet) (Puritan's Pride,Oakdale, NY, USA) are crushed, then dissolved in 5-10 ml of distilled water , then administered via an orogastric tube.
