To compare the clinical, obstetric and neonatal parameters between patients with > 34-week gestation having severe preeclampsia receiving magnesium sulphate and those with > 34-week gestation with preeclampsia but not receiving magnesium sulphate.

Materials and Methods

Single-centre prospective study studied 60 patients in each of the two groups. Magnesium sulphate was administered by Pritchard regimen as per standard protocol. Standard obstetric management was followed for both groups. In the severe preeclampsia/eclampsia group, maternal blood sample was analysed for serum magnesium levels. The duration of exposure, the amount of magnesium sulphate received and time elapsed between last dose of magnesium sulphate and delivery were all noted. Neonatal assessment was done. The various parameters including age, parity, blood pressure, mode of termination of pregnancy, NICU admission rate, incidence of hypotonia in the newborn and other neonatal parameters were tabulated and compared.


The two groups were comparable with respect to age and parity. Need for induction of labour was higher in the group with severe preeclampsia/eclampsia. Rate of LSCS and birth weights were comparable between the two groups. NICU admission rate and incidence of hypotonia were higher in those who received magnesium sulphate. Amount of magnesium sulphate received and total duration of magnesium sulphate did not correlate with NICU admission rates.


Neonatal morbidity, in terms of higher NICU admission rates and hypotonia, is higher in patients receiving magnesium sulphate.
