Resumo de Recurso
Hyperglycemia
Diabetic Ketoacidosis (DKA)
Lack of Insulin
Glucose can't enter cell
Cells Starved; Glucagon Released
Free fatty acids formed
Metabolized into ketones
Acetone smell respirations
Leads to metabolic acidosis
Excess ketones require kidneys to eliminate in urine
Sodium Buffer; pulls more water and electrolytes increasing volume depletion
Gluconeogenesis
More Glucose Released
Further elevated BGL
Glucose molecules produce osmotic diuresis
Large amount water drawn into renal tubules
Excessive Urination
Dehydration/ Volume Depletion
Hyperglycemic Hyperosmolar Nonketotic Syndrome (HHNS)
Lack of Insulin or Insulin Resistance
Glucose can't enter cell
Small amounts of circulating insulin prevent ketoacidosis
Elevated BGL creates hyperosmolar extracellular space
Intracellular Fluid pulled into extracellular space
Serum osmotic pressure pulls electrolytes from tissues
Serum Eletrolyte levels may appear normal or even elevated
Electrolytes actually extremely depleted at cellular level
Glucose molecules produce osmotic diuresis
Intravascular volume drastically depleted
Kidneys now hypoperfused
Circulatory Collapse
