When is magnesium sulfate typically administered in relation to labor and delivery?

Magnesium sulfate is primarily administered before and during labor to prevent seizures, especially in patients with conditions such as preeclampsia or eclampsia. This medication acts as a central nervous system depressant and has significant anticonvulsant properties, making it effective for managing the risk of seizure activity associated with hypertensive disorders in pregnancy.

By starting magnesium sulfate prior to labor, healthcare providers aim to provide optimal neuroprotection for both the mother and the fetus. It is crucial to maintain the medication during labor to ensure continued seizure prophylaxis, particularly during periods of increased stress and potential changes in maternal blood pressure.

This proactive approach helps to address the elevated risk of seizures in women experiencing severe hypertension and contributes to better overall maternal and fetal outcomes. Thus, administering magnesium sulfate before and during labor is a critical aspect of managing hypertensive disorders in pregnancy.
