Neonate: Myelomeningocele/Myeloschisis — Antibiotics for Infants with Postnatal Closure — Clinical Pathway: ICU

Neonatal Myelomeningocele/Myeloschisis Clinical Pathway — ICU

Antibiotic Recommendations for Infants in the N/IICU with Myelomeningocele/Myeloschisis

General Principles

  • Antibiotic goal administration time is within 1 hour of delivery in the SDU.
  • For infants with suspected sepsis, see the N/IICU sepsis pathway for antibiotic recommendations following fetal surgery.
  • Consider ID consult for infants with suspected infections.
  • UTI prophylaxis should be started at birth for infants not receiving broad-spectrum antibiotics for another reason. For patients receiving broad-spectrum antibiotics pre-operatively or for suspected sepsis, these broad-spectrum antibiotics provide adequate coverage for UTI prophylaxis.
  • UTI prophylaxis may be discontinued if a renal/bladder ultrasound is normal and the infant does not require clean intermittent catheterization, in discussion with urology.
