Hyperosmolar non-ketotic coma in diabetic stroke patients.

Abstract

Hyperosmolar non-ketotic coma in diabetes is a life-threatening condition. We describe three patients, aged 59-67 years, who developed hyperosmolar coma during the first ten days after admission for stroke. Common to all three were normal plasma osmolality and slightly elevated plasma creatinine levels on admission, treatment with diuretics, parenteral dextrose administration before and low urinary glucose output during the coma. In the five days preceding the coma, total fluid deficits were 3.8, 6.5 and 9.4 1, respectively. In one patient the rate of glucose delivery had clearly exceeded utilization during adequate insulinization, in another a marked reduction in urinary glucose output preceded extreme hyperglycaemia and coma. Two of the three patients died, both from extensive thrombus formation in cerebral arteries and multiple emboli to the lungs. We conclude that enhanced endogenous glucose production and reduced renal clearance of glucose may contribute to precipitate hyperosmolar non-ketotic coma. A close monitoring of fluid and dextrose administration seems mandatory in diabetic stroke patients, in particular if renal function is impaired or if diuretics are given. Insulin treatment should be considered in all diabetic patients during the first days after a stroke.
