Emergency anaesthesia in a patient with Gordon's syndrome.

Gordon's syndrome is a rare condition characterized by hypertension and hyperkalemia despite normal renal glomerular function. We report the administration of an anaesthetic to one such patient for an urgent surgical procedure. The patient's serum potassium was only marginally raised at the outset of the procedure. During surgery the serum potassium rose significantly, but responded to conventional management. Hyperkalaemia is a specific electrolyte disturbance that has numerous implications for the administration of an anaesthetic. Most importantly, there is a danger that further acute elevations may occur, caused by the surgery, the anaesthetic, or the condition itself
