  • Continue feeding every 2-3 hours
  • Repeat AC in 2-3 hours, before feed
  • Follow algorithm below based on glucose results
  • Continue to follow instructions based on result until there are 2 results, 6 hours apart, greater than or equal to 50
  • Notify practitioner if concern for any symptoms

Feed by mouth or gavage:
  • Breastfeed, expressed breast milk
    (any amount)
  • Formula, 5-10 mL/kg

Recheck Glucose
30 minutes after feed completed

Glucose <45
Notify Practitioner while proceeding:
  • Retest glucose at bedside
    • I-STAT or Accucheck
  • Send STAT lab glucose, but do not wait for result to proceed with pathway
  • If clinically stable feed expressed breast milk (any amount) or formula, 5-10 mL/kg
  • Practitioner may opt for NG feed
  • Recheck 1/2 hour after feeding ended – or 1 hour after last check

Glucose Actions
<30 Notify practitioner, IV Treatment Pathway
30-39

Notify practitioner

Feed Breastfeed or expressed breast milk or formula PO, gavage
Repeat AC 30 minutes after feeding finished
If <45 Notify practitioner, admit NICU / SCN
If ≥45 Repeat AC in 2-3 hours
40-49 Repeat AC in 2-3 hours
≥50 Repeat AC in 6 hours, if ≥50 may stop glucose monitoring
Note: Late preterm and SGA should have follow-up AC chem at 24-36 hours
Infants >24 hours old with glucose persistently 30-44 evaluate and treat with IV fluids
