Brief summary

Randomized pilot trial comparing scheduled morphine dosing with a weaning protocol to intermittent morphine dosing on an as-needed basis for newborns with neonatal abstinence syndrome.

Interventions

DRUGMorphine PRN

Dose given every 3 hours as-needed for severe NAS, defined by a threshold Finnegan score.

DRUGMorphine scheduled

Dose given every 3 hours on a scheduled basis and slowly weaned once stabilized.

Participant flow

Participants by arm

ArmCount
Standard
Infants randomized to the standard arm will receive morphine based on the current institutional treatment protocol: oral morphine 0.05 mg/kg/dose given every 3 hours, initiated if threshold Finnegan score is met. Once stabilized, dose will be weaned by 10% of peak dose per day until discontinuation. Morphine scheduled: Dose given every 3 hours on a scheduled basis and slowly weaned once stabilized.
9
Study
Infants randomized to the study arm will receive oral morphine 0.05 mg/kg/dose as needed for an elevated Finnegan score. May receive morphine as frequently as every 3 hours if needed. Morphine PRN: Dose given every 3 hours as-needed for severe NAS, defined by a threshold Finnegan score.
