RESUMO
OBJECTIVE: To assess the effectiveness of a reduced duration (12hours) of magnesium sulfate (MgSO4) administration for eclampsia. METHODS: In a prospective randomized study, women with eclampsia (prepartum, intrapartum, or postpartum) attending Jawaharlal Nehru Medical College, Aligarh, India, between January 2012 and September 2013 were enrolled. The inclusion criteria were blood pressure of at least 140/90mm Hg after 20weeks, proteinuria (dipstick value≥+1), and seizures not attributed to other causes. Participants were assigned to control and study groups according to the time of enrollment (6-month blocks). All patients received a MgSO4 loading dose (4g, intravenously), followed by maintenance doses (1g/hour) for 12hours (study group) and 24hours (control group). The primary outcome was recurrent convulsions after completion of MgSO4 therapy. Patients with treatment failure were excluded from analyses. RESULTS: Analyses included 132 patients in the study group and 72 patients in the control group. No convulsions recurred in either group after the completion of treatment. CONCLUSION: For women with eclampsia, 12hours of magnesium sulfate could effectively prevent recurrent convulsions.
