IRIS: Different Infusion Rates of Magnesium Sulphate Before Preterm Birth for Neuroprotection Trial.

ACTRN012605000765628

This trial has completed recruitment and early childhood followup is continuing.

The 2009 Doyle Cochrane systematic review established the neuroprotective role of antenatal magnesium sulphate for the preterm fetus, demonstrating that 63 women would need to be treated to benefit one baby by avoiding cerebral palsy (95% confidence interval 43 to 155). The 2010 Antenatal Magnesium Sulphate Prior to Preterm Birth for Neuroprotection of the Fetus, Infant and Child National Clinical Practice Guidelines, now recommend antenatal magnesium sulphate in women at risk of early preterm (gestational age less than 30 weeks), imminent birth (when early preterm birth is planned or definitely expected within 24 hours). The IRIS trial aims to assess the effect of administering antenatal magnesium sulphate for fetal neuroprotection at a slower loading infusion rate as compared with the current recommended infusion rate on maternal adverse effects.
