Anaphylactoid or carcinoid?

Abstract

A patient with a carcinoid tumour and a history suggestive of carcinoid syndrome, but with no biochemical evidence in support, had a cardiovascular collapse during an anaesthetic with propofol and suxamethonium. Subsequent investigations suggested an anaphylactoid reaction to suxamethonium, but there were features in common with a carcinoid crisis. The necessity for a second anaesthetic soon afterwards posed a dilemma. In the event of a similar reaction during another anaesthetic, a management plan beforehand should include ready availability of appropriate drugs and the use of sympathomimetic drugs that are less likely to exacerbate the situation.
