ABSTRACT
BACKGROUND: Gamma hydroxybutyrate (GHB) is used illicitly for its sedative hypnotic effects, and those who take it regularly are at risk of developing a substance use disorder. Withdrawal from GHB can include severe symptoms that may require medical management. For GHB use and withdrawal during pregnancy, there are no evidence- or practice-based guidelines to follow, and there is only minimal research literature. CASE SUMMARY: We present the case of a 32-year-old woman, G1P0 at 29 weeks and 6 days of gestation, admitted to the perinatal unit at a tertiary hospital for GHB withdrawal management and stabilization. GHB withdrawal was managed with a combination of baclofen and diazepam. We report the dosing and tapering of these medications throughout her 14-day admission. Withdrawal symptoms were well managed with this medication protocol, and she did not experience any features of complicated withdrawal. The patient later presented to hospital in preterm labor and precipitously delivered a healthy, preterm infant male at 34 weeks and 5 days of gestation. At 7 months postpartum, the patient continued to engage with perinatal addiction service, reported no use of GHB since her admission, and was parenting her healthy son. CLINICAL SIGNIFICANCE: There is a paucity of guidelines for managing GHB withdrawal in pregnancy. This case demonstrates good clinical outcomes administering a short-term combination of diazepam and baclofen during the third trimester of pregnancy. This case helps to fill a gap in the literature and may inform future research or clinical decision-making in similar situations.

OBJECTIVES: Evidence on the perinatal health of mother-infant dyads affected by opioids is limited. Elevated risks of opioid-related harms for people with opioid use disorder (OUD) increase the urgency to identify protective factors for mothers and infants. Our objectives were to determine perinatal outcomes after an OUD diagnosis and associations between opioid agonist treatment and birth outcomes. METHODS: We conducted a population-based retrospective study among all women with diagnosed OUD before delivery and within the puerperium period in British Columbia, Canada, between 2000 and 2019 from provincial health administrative data. Controlling for demographic and clinical characteristics, we determined associations of opioid agonist treatment on birth weight, gestational age, infant disorders related to gestational age and birth weight, and neonatal abstinence syndrome via logistic regression. RESULTS: The population included 4574 women and 6720 live births. Incidence of perinatal OUD increased from 166 in 2000 to 513 in 2019. Compared with discontinuing opioid agonist treatment during pregnancy, continuous opioid agonist treatment reduced odds of preterm birth (adjusted odds ratio: 0.6; 95% confidence interval: 0.4-0.8) and low birth weight (adjusted odds ratio: 0.4; 95% confidence interval: 0.2-0.7). Treatment with buprenorphine-naloxone (compared with methadone) reduced odds of each outcome including neonatal abstinence syndrome (adjusted odds ratio: 0.6; 95% confidence interval: 0.4-0.9). CONCLUSIONS: Perinatal OUD in British Columbia tripled in incidence over a 20-year period. Sustained opioid agonist treatment during pregnancy reduced the risk of adverse birth outcomes, highlighting the need for expanded services, including opioid agonist treatment to support mothers and infants.
