The regimens of Mg So4 for the management of severe preclampsia and eclampsia is known as
**Core Concept**
The management of severe pre-eclampsia and eclampsia involves administering magnesium sulfate (MgSO4) to prevent seizures and control blood pressure. This is based on the drug's ability to stabilize neuronal membranes and reduce neuronal excitability.
**Why the Correct Answer is Right**
Magnesium sulfate is administered intravenously in a regimen known as the "loading dose" followed by a "maintenance dose." The loading dose is 4-6 grams given over 20-30 minutes to rapidly increase serum magnesium levels. This is followed by a maintenance dose of 1-2 grams per hour to maintain therapeutic levels. The goal is to maintain a magnesium level between 4.8 and 9.0 mg/dL. This regimen is effective in preventing seizures in patients with severe pre-eclampsia and eclampsia.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not specify the correct dosing regimen for magnesium sulfate in the management of severe pre-eclampsia and eclampsia.
**Option B:** This option is incorrect as it does not mention the loading dose, which is a crucial part of the magnesium sulfate regimen.
**Option C:** This option is incorrect as it does not specify the maintenance dose, which is necessary to maintain therapeutic levels of magnesium.
**Clinical Pearl / High-Yield Fact**
It is essential to monitor magnesium levels closely in patients receiving magnesium sulfate for severe pre-eclampsia and eclampsia, as toxicity can occur with high levels. A magnesium level above 12 mg/dL can indicate toxicity.
**Correct Answer:** C.
