Whole-body Hypothermia Versus Normothermia in Mild Neonatal Encephalopathy: A Multicentre Randomised Controlled Trial

What this Trial Is About

Researchers are evaluating the safety and effectiveness of whole-body hypothermia for newborn babies with mild hypoxic ischaemic encephalopathy. This phase III randomised controlled trial aims to determine whether cooling the whole body to 33.5.5C within six hours after birth and continuing for 72 hours improves cognitive development at around two years of age compared with maintaining normal body temperature. The study also seeks to assess the economic value of cooling therapy for mild encephalopathy within the healthcare system. Babies born at or after 36 weeks with signs of birth asphyxia or acidosis will be randomly assigned to receive either whole-body hypothermia or targeted normothermia. Cooling will be applied using a servo-controlled machine in neonatal intensive care units, maintaining a rectal temperature of about 33.5C for 72 hours. The control group will have their body temperature kept at normal levels (37C) for the first 80 hours, with any fever carefully treated. Babies born at non-cooling centers will be transferred to specialized units for treatment. During the study, participants will undergo brain monitoring, MRI scans before discharge, and follow-up developmental assessments at 24 months using the Bayley Scales of Infant and Toddler Development IV. Additional evaluations will include neurological exams, motor function assessments, vision and hearing tests, and parent-completed questionnaires. Researchers will collect detailed clinical data from birth through hospital stay, aiming to compare cognitive outcomes and safety measures between the two groups over the study period.
