Effects of indomethacin prophylaxis timing on intraventricular haemorrhage and patent ductus arteriosus in extremely low birth weight infants.

Abstract

Indomethacin prophylaxis (IP) reduces the risk of intraventricular haemorrhage (IVH) and patent ductus arteriosus (PDA) in preterm infants. However, the optimal time to administer IP has not been determined. We hypothesised that IP at ≤6 h is associated with a lower incidence of IVH or death than if administered at >6-24 h of age.
