Abstract
We describe three critically ill patients who received drugs with K(ATP) channel-opening properties and subsequently developed severe life-threatening complications, including hyperkalaemia and cardiovascular disturbances. Administration of the sulfonylurea-receptor inhibitor glibenclamide promptly reversed these abnormalities. Over the past 3 years, we have seen this syndrome and response in five patients taking nicorandil, ciclosporin, or isoflurane, which suggests that this disorder arises more frequently than is currently realised.
