The purpose of this study is to determine the degree to which Docosahexaenoic acid (DHA) supplementation reduces the incidence of bronchopulomonary dysplasia (BPD), as assessed by the requirement for supplemental oxygen and/or assisted ventilation at 36 weeks post menstrual age.
Born at less than 29 weeks gestational age Within 3 days of commencing enteral feeds Has a legally acceptable representative capable of understanding the informed consent document and providing consent on the infant’s behalf
Infants who have a major congenital or chromosomal abnormality will be excluded from the study Women providing breast milk who are taking supplements providing >250 mg DHA per day and do not wish to stop taking supplements. Infants participating in another fatty acid study. Infants receiving intravenous lipid emulsions containing fish oil given as early lipid parenteral nutrition support.

Sex Both males and females
Condition category Bronchopulmonary dysplasia , Preterm infants
Condition code Reproductive Health and Childbirth , Respiratory
Intervention code Prevention
Tuna oil emulsion containing 120 mg/mL of DHA to provide 60 mg/kg/day of DHA (0.17 ml/kg three times a day). The intervention will be given enterally within 72 hours of the first enteral feed and continue until 36 weeks post menstrual age or discharge home (whichever occurs first).
Control group Placebo
Soy oil emulsion with no additional DHA given at 0.17 mL/kg three times a day. The control will be given enterally within 72 hours of the first enteral feed and continue until 36 weeks post menstrual age or discharge home (whichever occurs first).
Outcome: The primary outcome bronchopulmonary dysplasia will be defined on a physiologic basis that combines oxygen and ventilation support with an assessment of saturation.Timepoint: The diagnosis of bronchopulmonary dysplasia will be determined at 36 weeks postmenstrual age (36 weeks and 0 days to 36 weeks and 6 days inclusive) or day of discharge home, whichever occurs first.
Outcome: Intelligence, as reflected by a Full Scale Intelligence Quotient score. Overall intelligence will be assessed by a psychologist using the Wechsler Preschool and Primary Scale of Intelligence - Fourth Edition (WPPSI-IV) Australian and New Zealand Standardised Edition. A pre-defined subsample of n=707 children will be eligible to participate in the cognitive assessment. Children will be eligible if they have not died or withdrawn from the trial, and if were born and enrol .... Read more
