Efficacy and Safety of 1 g Vs 2 g Per Hour Intravenous Maintenance Dose of MgSO4 in Women With Severe Pre-eclampsia

Phase 4
Completed
Conditions
Severe Preeclampsia
Interventions
Registration Number
NCT03164304
Lead Sponsor
Assiut University
Brief Summary

Preeclampsia is commonly viewed as one of the hypertensive pregnancy disorders, which cover a spectrum of clinical presentations from chronic hypertension ( hypertension occurring prior to 20 weeks of gestation) and gestational hypertension (hypertension occurring after 20 weeks of gestation) To more severe forms, including preeclampsia, eclampsia (its convulsive form), and HELLP syndrome (hemolysis, elevated liver enzyme S, and low platelets)

Detailed Description

Treatment for patients who have developed preeclampsia or eclampsia mainly consists of control of hypertension, magnesium sulphate for prevention of eclampsia and convulsions, and planning for delivery.

Magnesium sulfate has been used to prevent eclamptic convulsion since 1925, its efficacy was confirmed by a large randomized controlled trial in 2002. Eclampsia could be prevented in more than 50% after magnesium sulfate administration . The World Health Organization recommended magnesium sulfate as the most effective, safe, and low-cost drug for the prevention of seizure in severe preeclampsia and eclampsia . The recommended dose of magnesium sulfate is 4 to 6 gram intravenous loading dose, followed by maintenance intravenous drip at the rate of 1 to 2 gram per hour .

Although different magnesium sulfate regimens have been tested, two dosing regimens are internationally recommended and widely used. The Pritchard regimen is a predominantly intramuscular regimen given as a loading dose of 4 g intravenously , and 5 g Intramuscular into each buttock followed by a maintenance dose of 5 g Intramuscular every 4 hours. This regimen is popular in resource-limited settings where intravenously administration of magnesium sulfate may not be feasible. However, it is associated with pain and a higher risk of infection at the injection site.

The Zuspan regimen is given as a 4 gram intravenously loading dose followed by continuous intravenously infusion of 1 gram per hour.

Either 1 gram or 2 gram maintenance dose of Magnesium Sulphate has been reported to reduce the development of eclampsia. Randomized controlled trials offering direct comparison between these 2 doses are lacking.
