Mild severity

Chemical inflammation / irritation of airways, no antibiotic required

Notes:

Moderate severity - First line

Important: Therapy

Oral Amoxicillin

* Contraindications to ceftriaxone:

  • Concomitant treatment with intravenous calcium (including total parenteral nutrition containing calcium) in premature and full-term neonates
  • Full-term neonates with jaundice, hypoalbuminaemia, acidosis, unconjugated hyperbilirubinaemia (bilirubin greater than or equal to 200 umol/L), or impaired bilirubin binding
  • 41 weeks or less corrected gestational age

Notes: If ceftriaxone is contra-indicated give IV Cefotaxime.

For oral switch, seek advice from paediatric infectious diseases consultant or microbiology.

Anaphylactic reaction to penicillin:

Oral Clindamycin (6mg/kg per dose, maximum 450mg per dose)

+ oral Ciprofloxacin#

# check important safety information in BNFC and provide Medicines for Children: Ciprofloxacin information for parents and carers.

Notes:

IV clindamycin and ciprofloxacin may be used if the oral route is compromised.

Important: Notes

Assessment of severity should be based on clinical judgement. Markers of severity include:

  • Significant tachypnoea*
  • Significant tachycardia*
  • Severe respiratory distress (significant recession (age < 12 months), nasal flaring, grunting)
  • Apnoeas (ages < 12 months)
  • Hypoxia (sustained O2 sats ≤ 92% in room air)
  • Cyanosis
  • Signs of severe dehydration
  • Capillary Refill Time > 2 seconds

If features of sepsis, for urgent senior input.

*Parameters for significant tachycardia / tachypnoea:

Age < 12 months: RR > 70, HR > 170,

Age 1 year to < 3 years: RR > 50, HR > 150,

Age 3-5 years: RR >50, HR > 140,

Age 5 to 14 years: RR > 40, HR > 120,

Age 14-17 years: RR >30, HR > 100
