Nonketotic hyperglycemia hyperosmolar coma

Non ketemic hyperglycemic hyperosmolar coma (NKHHC) is a complication of type 2 diabetes, with a mortality rate of over 50%. Often after symptomatic hyperglycemia for a period of time, fluid intake is insufficient to prevent severe dehydration induced by hyperglycemia induced osmotic diuresis. This syndrome is characterized by hyperglycemia, severe dehydration, hyperosmolarity, resulting in disturbance of consciousness, sometimes accompanied by epilepsy. The inducement may be accompanied by acute infection or other conditions (such as the elderly living alone).
