Eclampsia contributes significantly to maternal and perinatal morbidity and mortality in Nigeria. The world Health Organisation recommended Magnesium Sulphate as the most effective, safe and low cost drug for the treatment of eclamptic seizures and for prophylaxis in severe pre-eclamptic.This study is aimed to evaluate the effect of the introduction of magnesium sulphate for the management of eclamptic seizures on maternal and fetal indices in Aminu Kano Teaching Hospital [AKTH], Kano. A retrospective study of all patients who presented with eclampsia in AKTH, Kano. The study period included 3years prior to introduction o magnesium sulphate [January 2002- December 2004] and 3years after its introduction [January 2005 – December 2007]. During the study period, the prevalence of eclampsia was1.02% [1: 97 deliveries]. Sixty six [50.5%] of the patients were aged 19 and below. Approximately 62% of the patients were primigravida and 87% were unbooked. Thirty eight [29%] were treated with diazepam while ninety three[71%] were treated with magnesium sulphate. 39.4% of those treated with diazepam died compared to 15% of those treated with magnesium sulphate. Approximately ninety percent of those that died had no antenatal care. Overall perinatal mortality rate in this study was 312 per 1000 births . 368.4per 1000 births among those treated with diazepam and296.7 per 1000births in the magnesium sulphate group. Approximately nine percent of those treated with magnesium sulphate develop toxicity [85.5% renal and12%respiratory]This study is in support of the findings that magnesium sulphate is superior to diazepam in the reduction of maternal morbidity andmortality.Keywords: Eclampsia, magnesium sulphate, diazepam, AKTH, Kano.
