DKA HHS
Pathophysiology Insulin deficiency ► mobilize fatty acids ► ketogenesis Hyperglycemia ► osmotic diuresis ► volume depletion
Glucose >250 >600
pH <7.3 >/= 7.3
AG Positive Variable
Bicarb <18 >18
Ketones Positive in blood and urine None to small
Serum Osm Variable >320
  • Precipitants: Insulin deficiency, Iatrogenic, Infection, Inflammation, Ischemia, Infarction, Intoxication

Management initial testing: CBC, CMP, Mg, Phos, serum ketones, A1c, UA, ABG, EKG, cultures (if febrile), CXR, serum Osm

calculate serum osm= 2 x Na + (glucose/18) + (BUN/2.8)

calculate corrected Na = measured Na + 0.016 x (glucose- 100)

labs: Q1hr glucose, Q2-4hr BMP

algorithms as below (per UpToDate)
