Warning

Micro Organisms

Coliforms, Staphylococcus aureus, Pseudomonas spp (rare)

Review previous microbiology results prior to prescribing. Tailored antibiotic regime may be required.

Duration

5 days

If slow response, treatment can be extended up to a total of 10 days.

Review IV therapy after 24- 48 hours.

Seek advice from paediatric infectious diseases consultant or microbiology if no improvement after 48 hours.

First line - age over 1 month

Important: Therapy

Oral Co-amoxiclav

Notes:

IV co-amoxiclav may be used if the oral route is compromised.

Penicillin allergy - age over 1 month

Important: Therapy

Oral Clarithromycin

Notes:

IV clarithromycin may be used if the oral route is compromised.

Severe infection or age less than 1 month

Important: Therapy

IV Ceftriaxone* or IV Cefotaxime

* 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.

In the absence of microbiology results use Co-amoxiclav for oral switch.

Severe infection – penicillin allergy – all ages

Important: Therapy

Non-anaphylactic reaction to penicillin:

IV Ceftriaxone* or IV Cefotaxime

* 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:

IV Ciprofloxacin#

+ IV Teicoplanin

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

Notes:

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

Important: Notes

If less than 5 days since admission to hospital and no additional risk factors (e.g. immunosuppression, neurodisability, home non-invasive ventilation (NIV), recent influenza infection, recent broad spectrum antibiotic use or frequent healthcare contact) then treat as Community-acquired pneumonia

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
