Nonketotic hyperosmolar syndrome, also known as hyperglycaemic, hyperosmolar non-ketotic (HHNK) syndrome, is an uncommon complication of untreated diabetes mellitus.
- It is an emergency.
- It is characterized by extremely high blood glucose levels.
- It results in hyperosmolality--dehydration on a cellular level.
- There is minimal ketosis; that is little or no ketones show in the urine.
- The brain is affected and coma may result.
Animals with this syndrome need:
- IV rehydration, more so than with diabetic ketoacidosis.
- Replacement theraphy for potassium and phospate losses.
- A slow reduction in their blood glucose levels.
Unfortunately, the prognosis for recovery from the syndrome is poor.
