Abstract

Background: Severe hyponatremia is a very rare, mortal complication of preeclampsia and has been described in fourteen cases. Case presentation: A previously well, 29-year-old woman, gravida 2, para 1, was admitted at 34 weeks’ gestation with premature contractions. Her blood pressure was 150/90 mm Hg in both arms and she had mild proteinuria. On the third day of hospitalisation, sodium level was 120 mEq/L. On the same day, patient started to have headache. Cesarean delivery was performed because of prior cesarean section. On the first postoperative day, serum sodium level fell to 115 mEq/L. Patient had a generalised seizure After 24 hours of oral fluid restriction and 50 ml/hour isotonic sodium chloride administration, serum sodium increased to 127 mmol/L and by 48 hours, it returned to normal. Conclusion: The prediction, prevention and management of hyponatremia in preeclamptic patients require attention since this condition may predispose to convulsions, maternal mortality and fetal damage.

Summary

Introduction

Severe hyponatremia is a very rare, mortal complication of preeclampsia and has been described in fourteen cases.Case presentation: A previously well, 29-year-old woman, gravida 2, para 1, was admitted at 34 weeks’ gestation with premature contractions. Our case is a preeclamptic patient, presented with severe hyponatremia and convulsion. We discussed preeclampsia as a rare cause of severe hyponatremia that should be an indication for delivery. Preeclampsia in twin pregnancies may be an independent risk factor for severe hyponatremia.
