Study Notes
Diabetic Ketoacidosis
- Decreased insulin or increased metabolic demand leads to liver increasing lipolysis and using fatty acids for energy via ketogenesis.
- Fruity (acetone) breath odor
- Kussmaul's breathing
- Abdominal pain
- Dehydration
- Psychosis
- Vomiting
- Delirium
- Nausea
- Metabolic acidosis (increased H+, decreased HCO3)
- Hyperkalemia (total K+ depletion)
- Hyperketonuria
- Hyperketonemia
- Leukocytosis
- Insulin allows glucose and K+ cell entry, decreased intracellular K, increased serum K
- Complications: cerebral edema, cardiac arrhythmias, heart failure, mucormycosis
- Treatment includes fluid resuscitation, short-acting IV insulin, potassium replacement, and glucose replacement
Hyperosmolar Hyperglycemic State
- In severe hyperglycemia, glucose blocks kidney tubule reabsorption, increasing osmotic pressure and urine output, leading to severe dehydration.
- Hyperglycemia (greater than 600 mg/dL)
- Serum osmolality (greater than 320 mOsm/kg)
- Focal neurologic deficits
- Dehydration
- Polyuria
- Lethargy
- Seizures
- Thirst
- Insulin present, ketones absent
- Potassium effect: insulin allows glucose and potassium cell entry, decreased intracellular potassium and increased serum potassium
- Complications: coma, death
- Treatment: fluid resuscitation, short-acting IV insulin, potassium replacement, glucose replacement
Hypoglycemia
- Causes: inadequate food intake, high-dose insulin, exercise
- Neurogenic (autonomic): hypoglycemia awareness, diaphoresis, tachycardia, tremor, anxiety, hunger
- Neuroglycopenic: hypoglycemic unawareness, altered mental status, seizures
- Hypoglycemia (less than 70 mg/dL) (3.9 mmol/L)
- Normal laboratory values
- Complications: coma, death
- Treatment: fluid resuscitation and glucose replacement
