II. Risk Factors: Post-ICU Malnutrition

  1. Prolonged ICU admission
  2. Intubation or Tracheostomy (may interfere with swallowing)
  3. Prolonged period of poor oral intake (bowel mucosa atrophy)
  4. Sepsis

III. Management

  1. Nutrition Consultation

IV. Complications

  1. Acalculous Cholecystitis
    1. Poor lipid intake results in bile stasis
  2. Muscle wasting
    1. Total body protein loss exceeds 2 pounds for a 3 week ICU admission
    2. Initial (first 10 days): Skeletal muscle is primary source of lost protein
    3. Later (after 10 days): Visceral muscle is lost
