Objective: To evaluate the outcome of the use of MgSO4 therapy in women with severe pre-eclampsia in Kuwait from January 2002 to December 2004. Subjects and Methods: The study involved 450 women managed at the Maternity Hospital in Kuwait with a blood pressure of 160/110 mm Hg and proteinuria of >0.3–5 g/24 h. A loading dose of 4 g MgSO4 was administered intravenously over 20 min and then the maintenance dose continued at 1 g/h for 24 h postpartum. Magnesium sulphate toxicity was monitored by urine output, deep tendon reflexes and serum magnesium levels and managed with an infusion of 10 ml of 10% calcium gluconate and cessation of magnesium infusion. Adjunct therapy included intravenous hydralazine 10 mg and labetalol 100 mg. The mode of delivery was determined after stabilizing the patient. Results: The women included Kuwaitis (n = 200, 44.4%), Asians (n = 129, 28.7%) and other Arabs (n = 116, 25.8%) with a mean age of 29.7 ± 6.7 years (primigravida: n = 233, 51.8%; other parities: n = 217, 48.2%). Antenatal complications included intra-uterine growth restriction (n = 136, 30.2%), oliguria (n = 39, 8.7%), haemolysis, elevated liver enzymes and low platelet count syndrome (n = 30, 6.6%), abruptio placentae (n = 20, 4.4%), eclampsia (n = 15, 3.3%), and preterm birth (n = 253, 55.2%). Caesarean section (n = 241, 53.6%) was the main mode of delivery. The perinatal mortality rate was 27 per 1,000. Magnesium sulphate toxicity observed as reduced tendon reflexes occurred in 14 (3.1%) patients and flushing, nausea and vomiting and blocked nostrils in 86 (19.1%). There was no association between adverse outcomes and maternal serum magnesium concentrations and no maternal mortality occurred. Conclusion: Magnesium sulphate was effective in preventing recurrence of eclamptic fits and safe for both mother and fetus.
