Final answer:
Magnesium sulfate is the effective treatment for managing convulsions related to eclampsia in pregnancy. It is administered under medical supervision and is preferred over other anticonvulsants like diazepam to improve outcomes.
Step-by-step explanation:
Magnesium sulfate has proven effective in the management of convulsions related to eclampsia, which is a severe complication of pregnancy. Although anticonvulsants like diazepam may also be administered to manage seizures, improving long-term prognosis and reducing the risk of brain damage, magnesium sulfate remains the treatment of choice. It is important to note that such treatments are provided under medical supervision and are not self-administered, as they are used in actively seizing patients to prevent further convulsions and potential brain injury.
