Neonatal Encephalopathy Clinical Trial
— COMETOfficial title:
Whole-body Hypothermia Versus Normothermia in Mild Neonatal Encephalopathy: A Multicentre Randomised Controlled Trial
The goal of this randomised control trial is to establish the safety and efficacy of whole-body hypothermia for babies with mild hypoxic ischaemic encephalopathy, inform national and international guidelines, and establish uniform practice across the NHS. The main questions it aims to answer are: 1. Does whole-body cooling (33.5+0.5°C) initiated within six hours of birth and continued for 72 hours, improve cognitive development at 24 (±2) months of age after mild neonatal encephalopathy compared with normothermia (37+0.5°C)? 2. Does a prospective trial-based economic evaluation support the provision of cooling therapy for mild encephalopathy in the NHS on cost-effectiveness grounds? Participants will have the following interventions: - Randomisation into one of the following groups - Whole body hypothermia group - Targeted normothermia group - Bayley Scales of Infant and Toddler Development 4th Edition (Bayley-IV) examination at 24 (±2) months of age. Researchers will compare the mean Cognitive Composite Scale score from the Bayley IV examination between the two groups.

Eligibility | Inclusion Criteria: All babies born at or after 36 weeks of gestation with a birth weight of 1800g or more with birth acidosis or requiring resuscitation at birth will be screened for eligibility. Parents will be approached for consent if the baby meets all the three (A + B + C) criteria below: A. Evidence of intra-partum hypoxia-ischemia defined as any of - (i) Apgar score of <6 at 10 minutes after birth; (ii) continued need for resuscitation, including endotracheal or mask ventilation, at 10 minutes after birth; (iii) severe birth acidosis defined as any occurrence of pH <7.00 or a Base deficit >16mmol/l in any cord or baby gas sample within 60 minutes of birth. B. Evidence of mild hypoxic ischaemic encephalopathy defined as - two or more abnormal findings in any of the six categories of the modified Sarnat examination (level of consciousness, spontaneous activity, posture, tone, primitive reflexes, and autonomic nervous system) but not meeting the diagnosis of moderate or severe hypoxic ischaemic encephalopathy on a standardised examination performed by a certified examiner between 1 to 6 hours of age. C. Normal amplitude on aEEG performed for at least 30 minutes between 1 to 6 hours of age. Normal amplitude will be defined as upper margin of the aEEG activity more than 10 microvolts and the lower margin more than 5 microvolts on a single channel aEEG. Exclusion Criteria: - Infants who meet the BAPM criteria for whole-body hypothermia - Infants without encephalopathy defined as less than two abnormalities on structured neurological examination. - Infants with major congenital or chromosomal anomalies identified prior to randomisation. - Infants with birthweight <1800g. - Infants who have already received sedation, muscle relaxation, or anti-convulsants prior to neurological assessment. |

Primary | Mean Cognitive Composite Scale score from the Bayley IV examination | The Bayley scales of Infant and toddler development IV is a validated and standardised scoring system that assesses development of three domains, that is cognition, language, and motor development. Babies who die or who cannot be assessed with the Bayley IV due to severe disability will be allocated a Cognitive Scale Composite score one point below the basal test score similar to the previous whole-body hypothermia trials. | 22 to 26 months | |
Secondary | Neonatal seizures | Definite seizures: seizures confirmed on EEG with or without clinical manifestations or Level 2-Probable seizure: clinically assessed focal clonic/ focal tonic seizure or seizures confirmed on aEEG. | During neonatal hospitalisation (Expected average of 2 weeks) | |
Secondary | Duration of intensive care. | Number of days of neonatal intensive care. | During neonatal hospitalisation (Expected average of 2 weeks) | |
Secondary | Duration of hospital stay. | Total number of days of inpatient care in a neonatal unit. | During neonatal hospitalisation (Expected average of 2 weeks). | |
Secondary | Duration of mechanical ventilation. | Number of hours on invasive ventilation through an endotracheal tube. | During neonatal hospitalisation (Expected average of 2 weeks). | |
Secondary | Duration of inotropic support. | Total number of hours on inotropic support. | During neonatal hospitalisation (Expected average of 2 weeks). | |
Secondary | Number of babies with bloodstream or cerebrospinal fluid positive infection. | Isolation of a pathogenic organism from blood or cerebrospinal fluid along with a clinical diagnosis of sepsis, at any time during neonatal hospitalisation. | During neonatal hospitalisation (Expected average of 2 weeks). | |
Secondary | Number of babies with thrombocytopenia or coagulopathy requiring transfusion of blood products. | Prolonged blood coagulation requiring blood products | During neonatal hospitalisation (Expected average of 2 weeks). | |
Secondary | Opioid use. | Total cumulative dose of morphine per kilogram of body weight. | During neonatal hospitalisation (Expected average of 2 weeks). | |
Secondary | Number of babies exclusively breastfeeding at hospital discharge. | Defined as the newborn receiving only breast milk the last feedings before discharge. | During neonatal hospitalisation (Expected average of 2 weeks). | |
Secondary | Brain injury scores on conventional magnetic resonance imaging | Defined as per Rutherford/NICHD staging. | During neonatal hospitalisation (Expected average of 2 weeks). | |
Secondary | Survival without any neurological impairment. | Score of >85 in all Bayley-IV domains (motor, language, and cognitive), normal neurological examination with no cerebral palsy (Gross motor function classification system score <1), no hearing or visual impairment (as reported by parents), and no seizure disorder. | 22 to 26 months | |
Secondary | Preschool Child Behaviour Checklist (CBCL 1½-5) | Completed by parents at the 24-month assessment to provide a standardised measure of children's behavioural outcomes on scales that assess internalizing and externalizing behaviour problems and a Total Problems Scale. Mean standardised T-scores on each scale will be compared between groups. The CBCL checklist will be completed after the Bayley IV assessments. | 22 to 26 months |
