ED Pathway for Evaluation/Treatment of Febrile Young Infants (0-56 Days Old)
  • Low Risk for Bacterial Meningitis:
    29-56 days old
    Full-term (≥37 weeks gestation)
    No prolonged NICU stay
    No chronic medical problems
    No systemic antibiotics within 72 hours
    Well-appearing and easily consolable
    No infections on exam
  • Blood:
    WBC ≥ 5,000 and ≤ 15,000
    Band to neutrophil ratio < 0.2
    (Bands/bands + neutrophils)
  • Enhanced UA:
    WBC < 10 /HPF
    Negative Gram stain
  • Chest x-ray (if obtained):
    No infiltrate

LOW RISK
  • No antimicrobials
  • Discharge
  • Assure NP follow-up call
*If data is incomplete (e.g. urine or blood could not be obtained), consider patient High Risk

Antimicrobial Therapy:
(Meningitic doses are used initially-see ED Febrile Infant Order Set)

0-21 days Ampicillin/Cefotaxime/Acyclovir
22-28 days
Ampicillin/Cefotaxime
29-56 days
Cefotaxime
 
Additional Considerations:
Add Vancomycin  Ill Patient
CSF WBC > 8 w/abnormal glucose or protein
Gram positive organism on Gram stain
   
Call ID Gram negative organism on Gram stain
Imipenem and Amikacin
   
HSV
Testing/

Treatment

Start Acyclovir for infants ≤ 21 days OR for infants 22 to 40 days with ≥ 1 of the following:
