Neonatal Abstinence Syndrome Treatment & Management

Medical Care
The large number of infants who suffer from neonatal abstinence syndrome (NAS) and the associated long-term morbidity mandate that affected infants be accurately identified and their treatment and support should be optimized.
- The assessment and management of neonatal abstinence syndrome pose difficulties for staff and families and have been hampered by a lack of prospective studies and by few research studies that specifically assess the merits of one management approach over another.
- Vomiting and diarrhea leading to dehydration and poor weight gain, in the absence of other diagnoses, are indications for treatment, even in the absence of a high drug-withdrawal score.
- In the delivery room, naloxone use is contraindicated in infants whose mothers are known to be dependent on opioids because of the risk of neonatal seizures from abrupt drug withdrawal. However, in the absence of a specific history of opioid abuse in a mother who has recently received narcotics, naloxone treatment remains a reasonable option in the delivery room management of a depressed infant if the infant continues to demonstrate respiratory depression after positive pressure ventilation has restored normal heart rate and color.
- Primary treatment of neonatal symptoms related to prenatal substance exposure should be supportive because pharmacologic therapy can prolong hospitalization and exposes the infant to additional agents that are often not necessary. The treatment for morphine administration has been reported to last 8-79 days.[24] This length of hospitalization interferes with maternal bonding, has potential for nosocomial infection, and is a major use of resources.[25]
- Pharmacotherapy for infants with more severe expression of neonatal abstinence syndrome is necessary to allow them to feed, sleep, gain weight, and interact with care givers. Approximately 30-91% of infants who exhibit signs of neonatal abstinence syndrome receive pharmacological treatment.
- Nonpharmacologic approaches include the following:
- Assess daily for signs of withdrawal, including sleeping habits, feeding patterns, and weight gain.
- Reduce the degree of ambient light exposure, minimize excessive noise, avoid unnecessary handling, and provide swaddling for settling.
- Provide frequent small feeds of hypercaloric formula.
Consultations
Interdisciplinary intervention for the mother and her offspring (and the father, when possible) should be available at all points of access to care. Professionals involved in this care should include obstetricians, neonatologists, pediatricians, nurses, nutritionists, mental health professionals, social workers, substance abuse counselors, and child development specialists, at a minimum.
Diet
Frequent small feedings are preferable and should provide 150-250 kcal/kg per 24 hours for proper growth of the infant undergoing significant withdrawal.
Activity
Swaddling, pacifiers, low lighting, oscillating cribs, and avoidance of abrupt changes in the infant’s environment can be helpful.
