Efficacy of Magnesium Sulphate and Phenytoin in the Management of Eclampsia

Abstract

Fifty pregnant women admitted with diagnosis of eclampsia were randomly allocated to magnesium sulphate (Group A) or phenytoin sodium (Group B) treatment group. Incidence of recurrence of seizures maternal as well as perinatal morbidity and mortality were compared in both the groups. Mean maternal age, parity and gestational age was similar in both the groups. Mean birth weight was significantly lower in Group B compared to Group A. Seizure frequency prior to hospitalization was 5.4 +/- 4.7 in Group A and 4.8-3.6 in Group B. Mean time interval between occurrence of first seizure and hospitalization was 9.6 +/- 3.5 hours in Group A and 11.8 +/- 9.3 hours in Group B, the difference was not statistically significant. Women treated with phenytoin had a higher incidence of recurrent seizures (10/25-40%) than those treated with magnesium sulphate (2/25-8%). Majority of the women treated with phenytoin (6/10-60%) had single convulsion after initiation of anticonvulsant therapy and 1 woman of each group had recurrent convulsions (75). There was no significant difference in perinatal outcome in both the groups. Maternal morbidity was comparable in both the groups and there was no maternal death in either of the groups.
