Management of Acute Watery Diarrhea in a Well-Appearing 3-Year-Old
The best initial management is oral rehydration solution (ORS) given at home, with 100-200 mL after each stool, along with continued normal feeding. 1
Why ORS is the Correct Answer
This child shows no signs of dehydration (active, no depressed fontanelles, no fever, no pain) and has uncomplicated acute watery diarrhea. The clinical presentation indicates prevention of dehydration rather than treatment of established dehydration. 1
Specific ORS Dosing for This Child
- For children over 2 years old: Give 100-200 mL of ORS after each watery stool 1
- Provide parents with a 2-day supply of ORS and demonstrate proper mixing and administration 1
- Increase normal fluid intake with home-available fluids (cereal-based gruels, soup, rice water) 1
Why Other Options Are Incorrect
Stool Bacterial Culture is NOT Indicated
- Stool cultures are not needed for routine acute watery diarrhea in immunocompetent children 1
- Cultures are only indicated for dysentery (bloody diarrhea), not watery diarrhea 1
- Laboratory studies are rarely needed when clinical assessment shows no dehydration 1
Hospital Admission for IV Fluids is NOT Indicated
- Admission is only necessary for severe dehydration (≥10% fluid deficit) with shock or near-shock 1
- This child has none of the criteria for severe dehydration: no lethargy, no prolonged skin tenting, no cool extremities, no decreased capillary refill 1
- Oral rehydration is successful in >90% of cases and should not be bypassed for IV fluids 2
Dietary Management Alongside ORS
- Continue normal age-appropriate diet immediately - there is no justification for "resting the bowel" through fasting 1
- Offer freshly prepared foods including starches, cereals, fruits, and vegetables 1
- Encourage eating as much as the child wants, offered every 3-4 hours 1
- Avoid foods high in simple sugars and fats 1
Critical Warning Signs for Parents
Instruct parents to return immediately if the child develops: 1
- Continues to pass many watery stools
- Becomes very thirsty
- Develops sunken eyes
- Develops fever
- Becomes lethargic or less active
- Shows decreased urine output 1
Why Antibiotics Are Contraindicated
- Antimicrobial drugs are contraindicated for routine treatment of uncomplicated watery diarrhea 1
- Antibiotics should only be considered when dysentery is present, high fever occurs, or watery diarrhea persists beyond 5 days 1
- This child has none of these indications 1
Common Pitfall to Avoid
The most common error is premature hospitalization or IV fluid administration when a child has no clinical dehydration. This child is active, well-appearing, and has normal vital signs - these are clear indicators that outpatient ORS management is appropriate and sufficient. 1, 2
