Intrapartum and postpartum analgesia for women maintained on buprenorphine during pregnancy.

Objective: To determine whether buprenorphine maintenance alters intrapartum or postpartum pain or medication requirements.

Methods: Sixty three patients treated with buprenorphine for opioid dependence during pregnancy (vaginal n = 44; cesarean n = 19) were matched retrospectively to control women. Analgesic medication and pain scores (0-10) were extracted from the medical record.
