Maternal and perinatal outcome of severe pre-eclampsia in Enugu, Nigeria after introduction of Magnesium sulfate

Abstract

Background: Magnesium sulfate (MgSO4) is the most effective seizure prophylaxis in the management of severe pre-eclampsia, and its use is progressively spreading in our environment. It was introduced at the pioneer teaching hospital of southeastern Nigeria in 2007. A study on the outcome of its use is therefore necessary.

Objectives: The objective was to determine the effect of introducing MgSO4 on the maternal and perinatal outcomes of severe pre-eclampsia in Enugu, South eastern Nigeria.

Materials and methods: A retrospective study of all cases of severe pre-eclampsia managed at the University of Nigeria Teaching Hospital Enugu (UNTH), Nigeria, from 1 January 2005 to 31 December 2008 - 2 years before, and 2 years after the introduction of MgSO4 - was performed.

Result: The prevalence of severe preeclampsia within the study period was 3.3%. The mean age of study participants was 24.5 ± 2.9 years. Thirty women received MgSO4 while 47 women received diazepam. Eclampsia occurred only in a member of the diazepam group but there were no maternal deaths. Babies from the diazepam group were more likely to have low 1 minute Apgar scores but the association was not significant [OR = 3.08 (95% CI 0.78, 13.33)]. Longer hospital stay was significantly lower among women who received MgSO4 [OR = 0.32 (95% CI 0.11, 0.93)]. Perinatal mortality did not differ between the groups.

Conclusion: MgSO4 is effective in the management of severe pre-eclamptics at the UNTH, Enugu. Therefore, its accessibility and wider use should be promoted.
