Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is characterised by increased water retention and sodium loss. SIADH can lead to severe hyponatremia which may result in serious and life threatening consequences including seizure, coma and respiratory arrest if not corrected.

In this rapid learning you will learn how to:

  • recognise the signs and symptoms of SIADH
  • assess the severity
  • initiate the right interventions and escalate care appropriately
