Phaeochromocytoma removal and postoperative hypoglycaemia

A case of postoperative hypoglycaemia following removal of a phaeochromocytoma is presented. The hypoglycaemia is due to a reactive rise in insulin and is augmented by alpha adrenoceptor blocking agents. Beta adrenoceptor blockers impair recovery from this hypoglycaemia. Frequent monitoring of blood glucose and the administration of an appropriate solution of dextrose both during and after this operation is recommended.
