Abdominal Pain — Acute Appendicitis

24-year-old male presents with 12 hours of periumbilical pain that has migrated to the right lower quadrant, low-grade fever, nausea, and anorexia.

Step-by-Step Approach

  1. Focused abdominal exam — check for McBurney point tenderness, rebound, guarding
  2. Order CBC (leukocytosis), BMP, urinalysis (rule out kidney stone/UTI), lipase
  3. CT abdomen/pelvis with IV contrast (gold standard for diagnosis)
  4. Make patient NPO
  5. IV fluids and pain management (ketorolac or morphine)
  6. Surgical consult for appendectomy once imaging confirms
  7. Start prophylactic antibiotics (cefoxitin or cefazolin + metronidazole) pre-op
  8. Advance clock to post-op, reassess, manage recovery

  • ⚠Delaying surgical consult while waiting for imaging
  • ⚠Missing peritonitis signs that indicate perforation — changes urgency
