Effect of Magnesium Sulfate on Prevention of Preterm Labour and Perinatal Outcome

Abstract

Background: Preterm labour is a major cause of maternal mortality in our country. Hypomagnesaemia during pregnancy could be an indirect cause of preterm labour. Magnesium has a role on uterine smooth muscle relaxation, which is the basis for the use of magnesium sulphate as a tocolytic agent.

Objective: This study was done to see the effect of magnesium sulfate to prevent preterm labour and perinatal outcome.

Materials and Methods: This study was carried out in Comilla Medical College & Hospital, from December 2011 to May 2012. Fifty pregnant women, both primi and multi with preterm labour were selected for the study.

Results: Study showed labour delayed >24 hours in 86% cases. And the majority of newborn (96%) had Apgar score in 5 minute was 8-10, 4% had Apgar score 7-8. The mode of delivery was vaginal in 70% cases and by c/s in 16% cases; among subject whose labour delayed more than 24 hours.

Conclusion: Intravenously administration of magnesium sulfate is safe, well tolerated and effective tocolytic agent for prolongation of pregnancy in preterm labour. It produces minimal harmful effects on mother and fetus.
