title: Antenatal magnesium sulphate exposure is associated with prolonged parathyroid hormone suppression in preterm neonates.
abstract: The effects of maternal magnesium sulphate treatment on neonatal mineral status and parathyroid hormone secretory response were studied in 8 exposed and 27 control preterm infants during the first 2 wk of life. Antenatal magnesium sulphate resulted in hypermagnesaemia during the first 3-7 d of life without affecting other serum mineral concentrations.
  
  
  CONCLUSIONS
  Early hypermagnesaemia was associated with hypercalciuria during the first 3 d and parathyroid hormone suppression up to the age of 2 wk in the exposed infants.
