Q

Pathophysiology

A
  • A “flare up” occurs which causes inflammation in the large intestine
  • Inflammation kills the cells of the lining
  • Forms ulcers which bleed & release pus/mucus
  • Colon can’t do its job by absorbing water & minerals
  • GI contents entering from small intestine that is liquid going through colon will mix with blood pus, blood and mucus
  • Inflammation causes the colon to want to empty frequently

Q

Complications

A
  • With have flare-ups and period of emotion which results in continuous inflammation in healing resulting in: pseudopolyps, scar tissue & narrowing
  • With severe cases: haustra (loses pouch like form) and appear as smooth “lead-pipe sign”
  • Rupture: repetitive ulceration results in small holes… leaks contents into abdominal cavity resulting in peritonitis -> septic shock
  • Toxic Megacolon: overwhelming inflammation dilates colon and becomes paralyzed… ruptures

Q

Nursing interventions

A

Monitoring vital signs
- Bowel movement & sounds
- Focus GI assessment
Abdominal pain, bloating, fever, tachycardia, hyperactive or diminished bowel sounds = peritonitis + toxic megacolon

NPO w/ IV hydration per MD order

Diet education
- foods that can cause flare ups such as high–fiber food, hard to digest (nuts popcorn, raw + veg), dairy, spicy or high-fats

Regular colon cancer screenings

Q

Medications

A

Goal: control flare-ups and maintain remission

Anti-inflammatory

  • 5-aminosalicylates: first line tx for mild to moderate e.g., sulfasalazine
  • Corticosteroids: not used for long term e.g., prednisone

Immuno-suppressors used when other meds not working or pt needs to be off steroids

  • Suppressors: “Imuran” suppresses immune response, can affect enzymes
  • Modulators: “Humria” * TNF-blockers , increased risk for TB
