Can omega 3 fatty acids improve respiratory outcomes in preterm infants?

In preterm infants born at <29 weeks gestation is an emulsion containing a higher amount of docosahexaenoic acid (DHA) more effective than an emulsion with no additional DHA in reducing the incidence of bronchopulmonary dysplasia at 36 weeks post menstrual age?

Brief summary

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.

Interventions

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).
