Summary
Brief summary
Infants born preterm have an increased risk of mortality and cerebral
palsy. Evidence from recent case controlled studies support animal
research that suggests maternal administration of magnesium sulphate may
reduce the risk of cerebral palsy and mortality in infants born very
preterm. It is important that these findings are tested in large
randomised controlled trials as soon as possible to assess whether
prophylactic treatment should be recommedned for clinical practice in
the case of women who are at risk of preterm delivery. Trial participants, trial research staff and all involved in clinical
care of participants were blinded.
Trial treatment packs of identical appearance, labelled only with unique
study number.
