Retropharyngeal Abscess in a Child Aged ≥4 Years with Abscess ≤25 mm in Stable Clinical Condition

This protocol addresses the management of retropharyngeal abscess in older children (aged ≥4 years) presenting with a small abscess (≤25 mm), stable clinical status, a patent airway, no septicemia, no neurovascular complications, and no prior anaphylactic reaction to penicillin.

Clinical Scenario
Children aged ≥4 years with a retropharyngeal abscess measuring ≤25 mm are less likely to require surgical drainage. When systemic stability is maintained and the airway is uncompromised, initial medical management is appropriate — with strict monitoring and surgical drainage reserved only when medical treatment fails to achieve the expected response.
Treatment Approach
Management involves supportive measures together with a course of high-dose intravenous broad-spectrum antibiotic therapy directed against both aerobic and anaerobic pathogens. The target is clinical improvement within 48 hours of initiating intravenous antibiotic therapy. Specific antibiotic classes, sequencing, step-down criteria, and surgical escalation thresholds are detailed in the full structured regimen →

References

  1. Starting from the evidence that children ≥ 4 years and with abscess ≤ 25 mm were less likely to need surgical drainage, it has been suggested that older children with small abscess in stable conditions initially receive a course of high-dose intravenous antibiotics, are strictly monitored and undergo surgery only when medical treatment fails.
  2. Considering the microbiological characteristics of DNIs, parenteral administration of broad-spectrum antibiotic therapy covering both aerobic and anaerobic pathogens is strongly recommended.
