Somatostatin-Induced Hyperkalemia in a Patient on Maintenance Hemodialysis
Abstract
A 65-year-old man, who had been undergoing maintenance hemodialysis for 20 years, suffering from severe postprandial hypotension was studied on 2 consecutive interdialytic days. The drop in blood pressure resulting from the oral administration of 75 g glucose was prevented by the concomitant infusion of somatostatin (350 μg/h), but this was accompanied by severe hyperkalemia (7.4 mmol/l). Suppression of insulin by somatostatin may have contributed to the hyperkalemia by impairing cellular potassium uptake. We conclude that although somatostatin prevents postprandial hypotension, hyperkalemia may limit its use in patients with end-stage renal failure
