Recognising and managing acute hyponatraemia.
A significant amount of clinicians' time is spent managing patients with complications arising from the use of sympatheticomimetic drugs such as cocaine and ecstasy, or MDMA. This article examines one of these complications, namely acute hyponatraemia, which can have life-threatening neurological consequences. Although there are few signs or symptoms of this condition, emergency clinicians should be able to recognise when it may have occurred, and should have a basic understanding of the role of sodium in autoregulation of cellular function, the different fluid compartments in the human body and the pathology of cerebral oedema. The article describes the importance of early recognition and swift treatment of acute hyponatraemia, as well as the methods for calculating fluid replacement to optimise chances of full recovery.
