Modified Finnegan Neonatal Abstinence Score (NAS)
Stratifies severity of opioid withdrawal in newborns.
The NAS should be monitored over time; protocols for management based on scoring may differ by institution but some studies suggest monitoring every 3-4 hours.
Management
Protocols for management based on scoring may differ by institution, but one study (Kocherlakota 2014) suggests the following:
-
Start scoring within 24 hours of birth and monitor every 3-4 hours.
-
For two consecutive scores ≥12 or three consecutive scores ≥8, initiate pharmacologic treatment.
-
If neither of the above, continue to monitor scores at every 3-4 hour intervals.
