    Summary

    Neonatal abstinence syndrome (NAS) impacts infant weight gain. Infants with severe NAS requiring treatment experienced delayed weight recovery compared to those with mild symptoms.

    Area of Science:

    • Neonatology
    • Pediatric Pharmacology
    • Infant Nutrition

    Background:

    • Neonatal abstinence syndrome (NAS) is a significant concern in newborns exposed to substances in utero.
    • Early weight gain is a critical indicator of infant health and development.

    Purpose of the Study:

    • To investigate early weight-change patterns in neonates with passive addiction.
    • To compare weight recovery between treated and untreated neonates with NAS.

    Main Methods:

    • Retrospective analysis of weight changes in 101 neonates with passive NAS.
    • Categorization of neonates based on abstinence severity and pharmacologic treatment (paregoric or phenobarbital).
    • Comparison of weight nadir, time to regain birth weight, and weight on day 10 between groups.

    Main Results:

    • Untreated neonates with mild NAS lost 4.0% of birth weight, reaching nadir on day 3 and regaining weight by days 7-8.
    • Treated neonates with severe NAS lost 6.3% of birth weight, reaching nadir on days 6-7 and regaining weight by days 13-14.
    • Treated neonates weighed 95g less than untreated neonates on day 10, despite similar birth weights and energy intake.

    Conclusions:

    • Severe NAS and its pharmacologic treatment are associated with abnormal early weight-change patterns and delayed weight recovery.
    • Individualized nutritional support alongside strict abstinence management is crucial for neonates with severe NAS.
    • Further research into optimizing nutritional strategies for these vulnerable infants is warranted.
