WebJul 31, 2024 · Osmolality is a measurement of the number of particles in a solution. This is a physical chemistry property of any water-based solution. Osmolality can be measured in the laboratory (based on freezing point depression). Tonicity refers to how much the particles in a solution pull water across a semi-permeable biological membrane.

"WebAnother symptom of HHNK coma, polyuria, occurs because the high plasma osmolality prevents the normal osmotic return of water to the blood by the renal tubules, and it is excreted in the urine. This leads to a decreased blood volume, which severely hampers the kidney's excretion of glucose and a vicious cycle is begun. " - Hhnk osmolality

WebHyperosmolar Hyperglycemic State. HHS (formerly termed hyperosmolar hyperglycemic nonketotic coma) is a life-threatening emergency, defined as severe hyperglycemia (usually >600 mg/dL), elevated plasma osmolality (>320 mOsm/kg), serum bicarbonate >15 mEq/L, arterial pH >7.3, negative serum ketones (can be mildly positive), and altered mental status. WebHHNK syndrome was the clinical presentation at diagnosis of new onset diabetes for all seven children. Three of seven children had a previously diagnosed developmental delay. The average Glasgow Coma Scale (GCS) score at presentation was 13 (range 9--15). Mean body mass index (BMI) at presentation was 32.7 kg/m (2) (n=6).
