What is the management approach for HHS?

• A. Only rest and hydration without insulin.
• B. Immediate dialysis.
• C. Fluid replacement, correction of electrolytes, administration of regular insulin, and monitoring for fluid volume excess.
• D. Treatment with antibiotics.

Answer: (C)

Managing Hyperosmolar Hyperglycemic State hinges on rehydration, correcting electrolytes, insulin therapy, and careful monitoring for fluid overload. The first priority is aggressive IV fluid resuscitation with isotonic saline to restore circulating volume, improve renal perfusion, and begin lowering the high serum osmolality. As volume status improves and blood glucose drops toward the 200–250 mg/dL range, switch to dextrose-containing fluids to prevent hypoglycemia while continuing insulin to steadily reduce glucose and osmolarity. Insulin should be given via IV infusion after initial fluids (or in parallel per protocol) to drive glucose into cells and suppress hepatic glucose production, but fluids must come first to avoid dangerous shifts in intravascular volume. Electrolyte correction is essential, especially potassium, because total body potassium is depleted even when serum levels seem normal or high; insulin and fluids can precipitate a rapid drop in potassium, so potassium replacement is started early and adjusted as labs guide. Throughout, monitor urine output, hemodynamics, and labs to avoid fluid volume excess and to detect electrolyte changes promptly. Dialysis is not routine management; it’s reserved for specific complications such as refractory electrolyte disturbances or renal failure. Antibiotics are only indicated if a precipitating infection is identified.
