The problem of peripartum dilutional hyponatraemia has the potential to cause severe harm to labouring women and their babies and it is likely that it is under-recognised. Physiological factors predispose pregnant women to hyponatraemia, especially where additional risk factors such as excessive oral intake, intravenous fluids and exogenous oxytocin are present. The purpose of this guideline is to reduce the risk of hyponatraemia through the expedients of:

  • Increased awareness
  • Accurate fluid balance monitoring
  • Earlier detection

The guideline is relevant to all healthcare professionals who come into contact with all women in labour and the immediate post-partum period, as well as to the women themselves and their carers.
