Treatment for Children with Diarrhea
The recommended first-line treatment for a child with diarrhea is oral rehydration solution (ORS), with specific fluid volumes based on age (50-100 mL after each stool for children under 2 years, 100-200 mL for older children), along with early reintroduction of age-appropriate diet. 1
Rehydration Therapy
Oral Rehydration Solution (ORS)
- Use reduced osmolarity ORS as first-line therapy for mild to moderate dehydration 1
- The American Gastroenterological Association recommends standard glucose-electrolyte ORS with:
- 75-90 mEq/L of sodium
- 20 mEq/L of potassium
- 65-80 mEq/L of chloride
- 10 mEq/L of citrate
- 75-111 mmol/L of glucose (2-2.5%) 1
- Dosing recommendations:
- Children under 2 years: 50-100 mL after each loose stool
- Children over 2 years: 100-200 mL after each loose stool 1
Monitoring Hydration
- Assess for signs of dehydration including:
- General appearance
- Eyes (sunken or not)
- Mucous membranes (dry or moist)
- Tears (present or absent)
- Capillary refill time
- Urine output
- Vital signs, especially heart rate and blood pressure 1
Dietary Management
- Resume age-appropriate diet during or immediately after rehydration
- Offer food every 3-4 hours
- Avoid foods high in simple sugars and fats 1
- Consider dietary modifications:
- Stop lactose-containing products if suspected lactose intolerance
- Reduce insoluble fiber intake
- Ensure adequate clear fluid intake (8-10 large glasses daily for older children) 1
Medications
Antimotility Agents
- Loperamide (Imodium) should NOT be given to children under 12 years of age with acute diarrhea 1, 2
- The FDA label clearly states loperamide is not for use in children under 12 years 2
Antibiotics
- Only indicated for specific bacterial pathogens
- First-line treatments for confirmed bacterial pathogens:
- Shigella: Azithromycin
- Campylobacter: Azithromycin
- Enterotoxigenic E. coli (ETEC): TMP-SMX (if susceptible) or Azithromycin
- Bacterial gastroenteritis: Third-generation cephalosporin or Azithromycin 1
Other Medications
- Antipyretics may be used for high fever
- Antiparasitic drugs only if intestinal parasites are confirmed
- Probiotics may be considered as adjunctive therapy 3
- Avoid unnecessary use of:
- Antiemetics
- Antidiarrheals
- Spasmolytics
- Intestinal antiseptics 3
Prevention and Follow-up
Prevention
- Emphasize proper hand hygiene
- Rotavirus vaccination is recommended to prevent rotavirus gastroenteritis 1
When to Seek Medical Attention
- No improvement within 48 hours
- Worsening symptoms
- Development of warning signs:
- Severe vomiting
- Persistent dehydration despite ORS
- Persistent fever
- Abdominal distension
- Blood in stool 1
Common Pitfalls to Avoid
Inappropriate use of antimotility drugs: Loperamide and other antimotility agents are contraindicated in children under 12 years 1, 2
Overuse of antibiotics: Antibiotics should only be used for specific bacterial pathogens, not for all cases of diarrhea 1, 3
Delaying reintroduction of food: Early feeding during or immediately after rehydration is recommended, not prolonged fasting 1
Using inappropriate ORS concentrations: Using solutions with high glucose content or hyperosmolar foods can worsen outcomes 4
Failing to recognize dehydration: Careful assessment of hydration status is crucial for appropriate management 1
