IBD

1. PATHOPHYSIOLOGY

   • • unknown cause
     • progressive, systemic autoimmune disorder
     • abnormal inflammation of any parts of GI tract
     • Discontinuous, “skip” lesions
   • • varied mucosal ulcerations
       • burrow gut wall
         • fistula
       • narrowed lumen
         • obstruction
       • cobble stone apperance

2. DIAGNOTIC TESTS

   • • Laboratories studies
       • Serology
         • CBC (anemia), C-reactive protein (CRP)
         • erythrocyte sedimentation rate (ESR)
           • monitor response to treatment
       • Stool studies
     • Imaging
       • confirm disease location and intestinal complications.
         • endoscopy
           • obtain tissue ->pathological evaluation
         • CT, MRI, contrast radiography

3. COLLABORATIVE CARE

   • Nutritional therapy
     • • No special diet →customized to fit pt.
       • a well-balanced diet

           • secondary treatment: malnutrition
       • Total parenteral nutrition (TPN)
         • when oral & enteral feeding is inadequate

       • Do not abruptly discontinue
         • HYPOGLYCEMIA RISK
     • • RISKS
         • Administration-related
           • Pneumothorax; Fluid excess/ pulmonary edema.
             • Monitor VS closely
           • sepsis, embolism, catheter occlusion
         • Formulation-related
           • nutritional imbalance; electrolyte imbalance
           • hypoglycemia, hyperglycemia
             • monitor blood glucose
   • Patient teaching
     • Ostomy care
       • • examine stoma daily
           • healthy stoma
             • moist, dark pink to red
