Opioid dependent pregnant and postpartum women their infants are a complex vulnerable population requiring individualized, comprehensive, multidisciplinary treatment. Though methadone maintenance in the setting of comprehensive service provision during pregnancy significantly improves outcomes for opioid women, its use has implications infant, most notably neonatal abstinence syndrome. Neonatal syndrome is comprised physiologic signs behaviors that indicate dysfunctional regulation central...

In a sample of methadone-maintained breastfeeding women and matched group formula-feeding women, this study evaluated concentrations methadone in breast milk among maternal infant plasma both groups.Eight (dose: 50-105 mg/day), lactating provided blood specimens on days 1, 2, 3, 4, 14, 30 after delivery, at the times trough peak levels. Paired foremilk hindmilk were obtained each sampling time. Eight subjects samples same days. Infant for groups day 14. Urine toxicological screening between...

Neonatal intensive care unit (NICU) and drug treatment costs were compared in two groups of pregnant abusing women: 100 admissions to a multidisciplinary program active at the time delivery 46 controls not entering treatment. Clinical measures included urine toxicology delivery, infant birthweight. Apgar scores need for duration NICU services. Cost costs. Treatment patients showed better clinical outcome with less use higher estimated gestational age, birthweight scores. Infants also likely...

Objective. Though methadone pharmacotherapy is the treatment of choice for opiate-dependence during pregnancy in USA, most methadone-exposed neonates develop neonatal abstinence syndrome (NAS). NAS expression widely variable among and only a subset requires pharmacotherapy. This study explores potential predictors severity, including aspects maternal substance use maintenance histories, concomitant exposure to other licit substances, individual differences intrinsic or infant factors that...

This study evaluates concentrations of methadone in breast milk and plasma among a sample methadone-maintained women the immediate perinatal period. Twelve methadone-maintained, lactating provided blood specimens 1, 2, 3, 4 days after delivery. Specimens were collected at time trough (just before dose) peak (3 hours dosing) maternal levels. Paired foremilk (prefeed) hindmilk (postfeed) obtained each sampling time. Although there was significant increase concentration over for postfeed time,...

Objective. Daily methadone maintenance is the standard of care for opiate dependency during pregnancy. Previous research has indicated that single-dose maternal administration significantly suppresses fetal neurobehaviours. The purpose this study was to determine if split-dosing would have less impact on neurobehaviour than administration.Methods. Forty methadone-maintained women were evaluated at peak and trough levels single- schedules. Monitoring sessions occurred 36- 37-weeks gestation...

This study examined the neurobehavioral functioning of neonates prenatally exposed to methadone (n = 11) or buprenorphine 10), who underwent Neonatal Intensive Care Unit Network Neurobehavioral Scale (NNNS) examinations on days 3, 5, 7, 10, and 14 post-delivery. Linear mixed model analyses revealed that NNNS scores arousal excitability showed significant differences between medications over time. Compared did not require medication treat neonatal abstinence syndrome (NAS), receiving...

Background: In addition to the well-known benefits of human milk and breastfeeding for mother infant, may mitigate neonatal abstinence syndrome severity in prenatally opioid-exposed infants. However, lack conclusive data regarding extent presence buprenorphine active metabolites makes recommendation buprenorphine-maintained women difficult many providers. Objective: This study seeks determine concentrations its (norbuprenorphine, buprenorphine-glucuronide, norbuprenorphine-glucuronide) milk,...
