Summary
Eligibility Criteria
Inclusion criteria
The infant will be assessed sequentially by criteria A, B and C listed below:
A. Infants =>36 completed weeks gestation admitted to the Neonatal Intensive Care Unit (NICU) with at least one of the following:
- Apgar score of = 16 mmol/L in umbilical cord or any blood sample (arterial, venous or capillary) within 60 minutes of birth
Infants that meet criteria A will be assessed for whether they meet the neurological abnormality entry criteria (B) by trained personnel:
B. Moderate to severe encephalopathy, consisting of altered state of consciousness (lethargy, stupor or coma) AND at least one of the following:
- hypotonia
- abnormal reflexes including oculomotor or pupillary abnormalities
- absent or weak suck
- clinical seizures
Infants that meet criteria A & B will be assessed by amplitude-integrated electroencephalogram (aEEG) (read by trained personnel):
C. At least 30 minutes duration of amplitude integrated EEG recording that shows abnormal background aEEG activity or seizures. There must be one of the following:
- normal background with some seizure activity
- moderately abnormal activity
- suppressed activity
- continuous seizure activity
Exclusion criteria
- Infants expected to be > 6 hours of age at the time of randomisation
- Major congenital abnormalities, such as diaphragmatic hernia requiring ventilation, or congenital abnormalities suggestive of chromosomal anomaly or other syndromes that include brain dysgenesis
