The landmark Magpie Trial randomized more than 10,000 women with preeclampsia to magnesium sulfate or placebo. Magnesium sulfate substantially reduced the risk of eclampsia and was associated with improvements in several maternal outcomes, without evidence of major harm to the fetus. The trial provided strong support for magnesium sulfate as a standard anticonvulsant strategy in severe preeclampsia. For obstetricians, the key clinical issue is not only prescribing magnesium but identifying which patients require it, monitoring reflexes, respiratory status and urine output, and ensuring rapid availability of calcium gluconate when toxicity is suspected. Blood-pressure control, evaluation for severe features and timely delivery remain separate components of care. The Magpie findings are especially useful in emergency simulation because they turn a high-stakes clinical scenario into a sequence of recognizable decisions: stabilize the mother, prevent seizure, assess maternal and fetal status and determine the appropriate timing of delivery.
