Pediatric Perforated Appendicitis with Diffuse Peritonitis and Septic Shock
Pediatric Perforated Appendicitis with Diffuse Peritonitis and Septic Shock - General Surgery clinical simulation case. A 7-year-old boy brought by his...
Age: 7 • Gender: Male • Setting: Emergency Triage
Clinical Presentation & History
A 7-year-old boy brought by his mother with 48 hours of abdominal pain that began around the umbilicus and migrated to the right lower quadrant. Pain worsened overnight, fever spiked to 39.5°C, and he is now lying still, grunting with each breath, refusing to move his legs. Previously healthy child with up-to-date immunizations. No prior surgeries. No known drug allergies. Mother reports he stopped eating yesterday and vomited twice.
Acute Resuscitation Milestones & Priorities
Clinical phases and key interventions encountered in this emergency module:
Pediatric septic shock requires weight-based fluid resuscitation (20 mL/kg boluses, reassess, up to 40-60 mL/kg) and antibiotics within 60 minutes of recognition. Each hour of delay increases mortality by ~5%.
Epinephrine is first-line vasoactive for fluid-refractory 'cold' pediatric septic shock; dopamine is no longer first-line due to arrhythmia risk.
Perforated appendicitis with diffuse peritonitis mandates emergent source control (appendectomy + peritoneal lavage + drain); delay multiplies bacterial load and cytokine injury.
Early enteral nutrition within 24-48 hours postoperatively preserves gut barrier function and reduces infectious complications compared with prolonged TPN.
Lactate normalization, urine output > 1 mL/kg/hr, and capillary refill < 2 sec are the key pediatric resuscitation endpoints.
