Cool Prime Study for Mild HIE

This study is looking at how different treatments affect babies born with mild Hypoxic Ischemic Encephalopathy (HIE), a condition where the brain doesn't get enough oxygen or blood flow around birth. Researchers want to compare two approaches: usual care (Normothermia), which keeps the baby's body temperature normal, and Whole body therapeutic hypothermia, which cools the baby's body for 72 hours. The goal is to see which treatment leads to better brain development at around two years of age and to understand any side effects of cooling. About 460 infants will be included. To join, infants must be born at 36 weeks or more and show signs of mild encephalopathy within 6 hours of birth.

Study design
This is an observational study involving about 460 infants. It compares two existing treatment approaches based on standard practices at different hospitals.

  • Effectiveness of normothermia in infants as measured by Composite Bayley IV score22-26 months of age.

    Effectiveness of normothermia in infants is measured by Composite Bayley IV score scale, which is. an extensive formal developmental assessment tool for diagnosing developmental delays in early childhood. Possible scores range from 55- 120 where lower scores indicate worse outcome.
