Magnesium sulfate
Eclampsia is the development of new convulsions in a pre-eclamptic patient that may not be attributed to other causes. It is a sign that the underlying pre-eclamptic condition is severe and is associated with high rates of perinatal and maternal morbidity and mortality. Warning symptoms for eclampsia in an individual with current pre-eclampsia may include headaches, visual disturbances, and right upper quadrant or epigastric abdominal pain, with a headache being the most consistent symptom. Magnesium sulfate is used to prevent convulsions in cases of severe pre-eclampsia.
