Hyperosmolar Hyperglycemic Nonketotic Syndrome, or HHNS, is a serious condition most frequently seen in older persons. HHNS can happen. Hyperosmolar hyperglycemic state is a life-threatening emergency manifested by marked eleva- ADA = American Diabetes Association. Hyperosmolar hyperglycemic state is a life-threatening emergency on recommendations from the American Diabetes Association (Figure 2).

However, they are warranted while awaiting culture results in older patients or in those with hypotension.
Kaminska ES, Pourmotabbed G. Maletkovic J, Drexler A. Diabetic ketoacidosis and infection: Arch Intern Med ; A prospective randomized study in patients with pH between 6. Then the insulin dose was decreased by half to 0. In adults, insulin should be started with an initial intravenous bolus of 0.
HHNS is usually brought on by something else, such as an illness or infection. Course and prognosis of patients with diabetic non ketotic hyperosmolar state.
Hyperosmolar Hyperglycemic Nonketotic Syndrome (HHNS): American Diabetes Association®
The choice of fluid for further repletion depends on the hydration status, serum electrolyte levels, and urinary output. Diagnosis and treatment of diabetic ketoacidosis and the hyperglycemic hyperosmolar state.
However, some of them may have ketonemia.
However, no controlled studies have shown improved outcomes with phosphate replacement. Work with your team to develop your own sick day plan.
Other pitfalls include artificial elevation of serum creatinine due to interference from ketone bodies when a colorimetric method is used DKA consists of the biochemical triad of hyperglycemia, ketonemia and high anion gap metabolic acidosis 12 Figure 2. More in Pubmed Citation Related Articles. Most recently, two new classes of medications have emerged as triggers for DKA. More recently, it has been proposed that consciousness level in adolescents with DKA was related to the severity of acidosis pH and not to a blood glucose levels Phosphate administration may result in hypocalcemia when used in high dose Electrolytes should be checked every one to two hours until stable, and the cardiac rhythm should be monitored continuously.
Hyperosmolar Hyperglycemic State
Umpierrez G, Freire AX. The mechanism for lowering glucose is believed to be due to osmotic diuresis and modulation of counter-regulatory hormone release 16 The AKA patients seldom present with hyperglycemia Epub Mar Moreover, there is a tendency to hypoglycemia rather than hyperglycemia with isopropyl alcohol injection 96 To prevent hypokalemia, potassium replacement is initiated after serum levels fall below 5. Urine or serum ketones. Journal of diabetes and its complications ; It also provides a simple method for calculating anion gap and serum osmolality.
Am J Emerg Med. Diabetic ketoacidosis in a community-based population. Coagulation abnormalities in diabetic coma before and hyperosmoar hours after treatment. There is no evidence that phosphate therapy is necessary in treatment for better outcome of DKA Age-Adjusted DKA hospitalization rate per 1, persons with diabetes and in-hospital case-fatality rate, United States, — 4.
Concomitantly, ketoacid anion is added into extravascular space resulting hyperlsmolar anion gap AG increase.
The pathogenesis of pulmonary edema may be similar to that of cerebral edema suggesting that the sequestration of hyperismolar in the tissues may be more widespread than is thought.
Similar results have been reported recently in pediatric patients with DKA Information from reference These ketone bodies have been shown to affect vascular integrity and permeability, leading to edema formation Increased lipolysis and its consequences on gluconeogenesis in non-insulin-dependent diabetes mellitus. Br Med J ; 3: This is followed by altered level of consciousness and lethargy. Physical findings in patients with HHS include profound dehydration with poor tissue turgor; dry buccal mucosa; soft, sunken eyeballs; cool extremities; and a hyperosmlar, thready pulse.
Regulation of hypeeosmolar and the renaissance of carnitine palmitoyltransferase. If the corrected sodium level remains low, hypertriglyceridemia secondary to uncontrolled diabetes should be also suspected.
Pitfalls of Laboratory Tests and Diagnostic Considerations for Interpreting Acid Base Status in DKA False positive values for lipase may be seen hypfrglycemic plasma glycerol levels are very high due to rapid breakdown of adipose tissue triglycerides glycerol is the product measured in most assays for plasma lipase.
This notion should particularly apply in the management of HHS in elderly and patients with multiple medical problems in whom it may not be clear how long these subjects experienced severe hyperglycemia prior to the admission to the hospital.
Subcutaneous use of a fast-acting insulin analog: Ketogenesis Excess catecholamines coupled with insulinopenia promote triglyceride breakdown lipolysis to free fatty acids FFA and glycerol.
The best way to avoid HHNS is to check your blood sugar regularly. A copy of the license can be viewed at http: Timely diagnosis, comprehensive clinical and biochemical evaluation, and effective management is key to the successful resolution of DKA and HHS.
Our study showed that glucose, bicarbonate, BUN and osmolality, and not pH were significantly different between non-comatose and comatose patients.
