Pediatric infection treatment

Pediatric infection treatment — differential diagnosis, rational antibiotic use, and viral infection management.

A process for the upper and lower respiratory tract, urinary tract, and rash-related illnesses seen in children that aims to provide accurate diagnosis, supportive care, and, when needed, the right antibiotic choice while avoiding unnecessary antibiotic use.

Indication

  • Symptoms of upper respiratory infection such as fever, sore throat, cough, and runny nose
  • Suspected acute otitis media (middle-ear infection), sinusitis, or tonsillitis
  • Lower respiratory infections such as bronchiolitis and pneumonia
  • Febrile urinary tract infection (especially in infants under 2 years)
  • Acute gastroenteritis (diarrhea-vomiting) and risk of dehydration
  • Rash-related illnesses (chickenpox, scarlet fever, hand-foot-and-mouth disease, etc.)

Preparation

  • The onset, level, and pattern of fever are recorded
  • Changes in the child's feeding, fluid intake, urine output, and overall condition are reviewed
  • Similar illness in daycare/school, siblings, or household members is assessed
  • Vaccination status and previous infections are reviewed
  • Previously used antibiotics and treatment responses are recorded

How it's performed

  1. A detailed physical exam evaluates the throat, ears, lungs, abdomen, and skin
  2. When indicated, rapid tests (throat culture, rapid strep test, urinalysis) or blood tests are ordered
  3. It is recognized that most upper respiratory infections are viral; in these cases, antibiotics are unnecessary and contribute to resistance
  4. When clear bacterial infection or high suspicion exists, antibiotics are selected based on age, weight, and susceptibility
  5. Supportive care for fever, pain, and mucus is arranged (paracetamol/ibuprofen, fluids, rest)
  6. The family is informed about the expected course, when to return, and home follow-up rules

Post-procedure

  • In children started on antibiotics, response is evaluated within 48-72 hours
  • Antibiotic courses should not be stopped early and should be completed for the full duration
  • After urinary tract infection, follow-up urine culture and imaging are planned when needed
  • In recurrent infections, underlying causes (immunodeficiency, anatomic abnormality, allergy) are investigated
  • The vaccination schedule is reviewed and any missed vaccines are completed

Risks

  • Disruption of gut flora, diarrhea, and resistance from unnecessary antibiotic use
  • Allergic reactions and rash from antibiotics
  • Risk of complications (mastoiditis, kidney damage, sepsis, etc.) when treatment fails or diagnosis is delayed
  • Side effects from incorrect dosing or timing of antipyretics

FAQ

If my child has a fever, are antibiotics needed right away?

No. The majority of febrile illnesses in childhood are viral and do not respond to antibiotics. The decision to start antibiotics should be based on examination and, when needed, test results.

What can I do to bring down a fever?

Light clothing, adequate fluids, and physician-recommended paracetamol or ibuprofen may be used. Aspirin is not used in children due to the risk of Reye's syndrome.

Can I stop antibiotics once my child feels better?

No. Stopping antibiotics early can cause the illness to recur and contribute to resistance. The course recommended by your physician should be completed.

When should I take my child to the hospital?

Severe lethargy, persistent vomiting, inability to take fluids, rapid breathing, bluish skin, fever with rash, or any fever in an infant under 3 months requires emergency evaluation.
