Bismuth dosing per age and formulation with pediatric gastroenterology guidance
Specialist involvement
Pediatric gastroenterology for endoscopy and regimen selection
Admission for significant bleeding or dehydration
Background
Epidemiology
Disease burden
Peptic ulcer disease as a leading cause of nonvariceal upper GI bleeding
Helicobacter pylori and NSAIDs as dominant etiologies
Complication patterns
Bleeding as most common acute complication
Perforation associated with higher mortality
Recurrence drivers
Persistent H pylori infection
Ongoing NSAID or aspirin exposure without gastroprotection
Pathophysiology
Core mechanism
Imbalance between mucosal defenses and acid pepsin injury
Ulcer crater formation in gastric or duodenal mucosa
Helicobacter pylori mediated injury
Chronic active gastritis
Increased acid output in antral predominant infection
Impaired mucosal defenses and inflammation
NSAID mediated injury
COX inhibition with reduced prostaglandin synthesis
Reduced mucus and bicarbonate production
Microvascular injury and impaired healing
Therapeutic Considerations
Proton pump inhibitor rationale
Higher intragastric pH improves clot stability in bleeding ulcers
Faster symptom relief and higher healing rates vs H2 blockers
Eradication rationale
H pylori eradication reduces ulcer recurrence and rebleeding
Test of cure required due to rising antibiotic resistance
Guideline aligned hemostasis strategy
High dose proton pump inhibitor for 72 hours after endoscopic hemostasis
Repeat endoscopy for recurrent bleeding
Transcatheter embolization as next step when endoscopy fails
Patient Discharge Instructions
copy discharge instructions
Medication and adherence
Proton pump inhibitor exactly as prescribed
Complete full antibiotic course if treated for H pylori
Avoidance and lifestyle
Avoid NSAIDs including ibuprofen and naproxen unless specifically advised
Avoid tobacco
Limit alcohol
Follow up and testing
Primary care or gastroenterology follow up within 2 to 4 weeks
Test of cure for H pylori at least 4 weeks after antibiotics
Hold proton pump inhibitor 14 days before test of cure when instructed
Return to emergency department immediately for
Vomiting blood
Black tarry stools
Fainting or near fainting
Chest pain or trouble breathing
Severe worsening abdominal pain
Persistent vomiting or inability to keep fluids down
Fever with severe abdominal pain
