Pediatrics: Age-Specific Assessment and Safe Empiric Decisions
Pediatrics: age-specific assessment
Pediatric questions depend on age. Know normal growth and development, feeding and output, immunization schedules, neonatal jaundice, dehydration, respiratory distress, congenital heart disease, asthma, seizures, and fever in the young infant. A 2-month-old with rectal temperature ≥38.0°C needs a full sepsis evaluation and empiric antibiotics after cultures, even if well appearing. By contrast, an older vaccinated child with a clear viral source may be observed if toxic appearance, hydration, and follow-up are acceptable. Dehydration is assessed by mental status, mucus membranes, tears, capillary refill, and urine output; severe dehydration needs isotonic fluid boluses and reassessment.
Traps
Do not apply adult vital-sign norms to infants. Do not miss congenital heart disease presenting with shock when the ductus closes. Distinguish febrile seizure from meningitis; obtain LP when meningitis is suspected or the infant is young. In asthma, give oxygen, inhaled bronchodilators, and systemic steroids early; do not rely on antibiotics. Check vaccination contraindications, especially live vaccines in significant immunocompromise.
Worked rule
For fever in an infant younger than 3 months, use rectal temperature and a low threshold for full sepsis workup. Age and appearance trump a reassuring nonspecific history.
