Safety and efficacy of low dose intramuscular magnesium sulphate (MgSO4) compared to intravenous regimen for treatment of eclampsia

摘要

Abstract Aim This study was performed to compare the safety and efficacy of low dose intramuscular magnesium sulphate (MgSO4) (Dhaka regimen) and intravenous (IV) MgSO4 (Zuspan regimen) for the prevention of eclampsia recurrence and to compare serum magnesium concentration. Methods Forty one eligible patients with eclampsia were randomly divided into two groups: group I patients received IV MgSO4 according to the Zuspan regime, while group II patients received intramuscular (IM) MgSO4 according to the Dhaka regimen (i.e. low dose MgSO4). The total dose MgSo4 requirements per patient were calculated and serum MgSo4 level was measured. Maternal and fetal outcomes were compared between the groups. Results The mean total dose of MgSO4 required for the treatment of eclampsia was higher in group I compared to group II (32?±?6.8?g vs 25.4?±?8.8?g, respectively; P 0.5). The mean serum MgSO4 levels were significantly higher ( P ??0.003) in group I compared to group II, although there were no significant differences in seizure recurrence. Statistically, more patients in group I experienced a loss of knee jerk reaction and required dose deferral compared to group II. There was a significantly higher number of babies with poor Apgar scores in group I. Overall the maternal and fetal outcomes were comparable between the groups. Conclusions A low dose IM regimen (Dhaka regimen) of MgSo4 is equally efficacious and safe compared to an IV regimen (Zuspan regimen) for the control and prevention of seizures in patients with eclampsia.
