TAKING CARE OF MOM

Prenatal Care
• Enrollment in an opioid maintenance program
• Minimizes cravings and optimizes maternal health
• Prevents fetal stress and suppresses withdrawal
• Anticipatory neonatal withdrawal
• Methadone is most commonly chosen
• Buprenorphine may shorten treatment duration and hospital stay
of the neonate
• Increased dropout rate with buprenorphine
• Increased doses may be required during 3rd trimester

Long-Term Outcomes
• Difficult to evaluate
• Confounding variables
• Withdrawal seizures respond to opiates and do not
necessarily carry an increased risk of poor outcomes
• Neurocognitive delays possible during infancy
• Working memory updating - Resolved at ~ 7 months
• Regulation and quality of movement
• Excitability
• Delay in milestones: Independent sitting, crawling

Take Home Points
• Pregnant women on methadone may require higher
doses during pregnancy
• Buprenorphine is now considered a safe, alternative
option for pregnant women enrolled in an opioid
maintenance program
• Breastfeeding is beneficial for NAS even while the mom
is still enrolled in the maintenance program
12
Assessment Question
• During which trimester is a pregnant woman most
likely to require her highest dose of methadone?
A. 1st Trimester
B. 2nd Trimester
C. 3rd Trimester
