What is the management approach for a 1-year-old child with recurrent vomiting and no fever?

Management of Recurrent Vomiting in a 1-Year-Old Without Fever

For a 1-year-old with recurrent vomiting and no fever, initiate oral rehydration with small, frequent volumes (5 mL every minute) using a spoon or syringe, continue age-appropriate feeding, and carefully assess for red flag signs that require urgent evaluation. 1

Immediate Assessment Priorities

First, determine the character of the vomiting to identify life-threatening conditions:

• Bilious (green) vomiting requires emergency evaluation for malrotation with volvulus or intestinal obstruction 1, 2
• Projectile vomiting suggests pyloric stenosis (though less common at 1 year) or other obstructive conditions and warrants urgent assessment 1, 2
• Non-bilious, effortless regurgitation without other concerning features is more likely benign 2

Assess for red flag signs that mandate immediate referral 3:

• Bilious or bloody vomiting
• Altered mental status or lethargy
• Severe dehydration (sunken eyes, no tears, decreased urine output)
• Abdominal distension or tenderness
• Inconsolable crying or excessive irritability

Hydration Management

The cornerstone of management is oral rehydration therapy (ORT), which is effective in over 90% of vomiting children 1:

• Start with 5 mL of oral rehydration solution (ORS) every minute using a spoon or syringe under close supervision 4, 1
• Gradually increase volume as tolerated 1
• Replace each vomiting episode with an additional 2 mL/kg of ORS 4
• Simultaneous correction of dehydration often lessens the frequency of vomiting 4

For children unable to tolerate oral intake due to persistent vomiting, ondansetron (0.2 mg/kg orally or 0.15 mg/kg parenterally, maximum 4 mg) may facilitate oral rehydration, though this is typically reserved for children >4 years 1, 3

Nutritional Management

Continue age-appropriate nutrition as soon as the child tolerates it 1:

• Breastfed infants should continue nursing on demand 4, 1, 2
• Formula-fed infants should receive full-strength formula if tolerated 4, 1, 2
• If formula intolerance is suspected (worsening diarrhea with reintroduction), consider lactose-free or lactose-reduced formulas temporarily 4, 2
• For toddlers on solid foods, continue their usual diet including starches, cereals, yogurt, fruits, and vegetables 4, 1
• Avoid foods high in simple sugars and fats 4, 1

Medication Considerations

Antibiotics and antiemetics are generally NOT indicated in the absence of fever and other signs of bacterial infection 4:

• Antibiotics should only be considered with high fever, dysentery, or symptoms lasting >5 days 4, 1
• Antimotility drugs should NOT be given to children <18 years 1
• Antiemetics are reserved for persistent vomiting preventing adequate hydration 1, 3

Differential Diagnosis Considerations

At 1 year of age without fever, consider:

• Gastroenteritis (most common, though typically has associated diarrhea) 3, 5
• Gastroesophageal reflux (common in first year of life, often related to overfeeding) 2
• Formula or food intolerance 4, 2
• Cyclic vomiting syndrome (stereotypic episodes with symptom-free intervals) 6
• Intussusception (though typically presents with severe pain and bloody stools)
• Intentional poisoning (rare but important to consider in atypical presentations) 7

When to Escalate Care

Instruct parents to return immediately if 4, 1:

• The child becomes irritable or lethargic
• Decreased urine output develops
• Vomiting becomes intractable or bilious
• Symptoms persist or worsen

Common pitfall: Assuming all vomiting in infants is benign gastroesophageal reflux. The absence of fever does NOT rule out serious pathology—bilious vomiting, projectile vomiting, and signs of obstruction require urgent evaluation regardless of temperature 1, 2, 3.

Home Management Instructions

Provide parents with specific guidance 4, 1:

• Offer small, frequent sips of ORS rather than large volumes
• Continue breastfeeding or formula feeding as tolerated
• Monitor for decreased wet diapers (fewer than 3-4 per day suggests dehydration)
• Keep a 24-hour supply of ORS at home for future episodes
