An in-depth look at the management of hyponatraemia, with special attention to a new concept called the “dDAVP clamp.”
– only treat hyponatraemia if symptoms are severe – coma, seizures or severe delirium
– use 3% saline 100ml, up to three doses
– consider giving dDAVP to prevent a rapid climb in the serum sodium
– aim to correct the serum sodium by only 3-6mmol/L in the first 24 hours
