A 27-year-old woman on buprenorphine-naloxone (Suboxone®) for treatment of opioid dependence is admitted to the hospital with severe abdominal pain due to a perforated gastric ulcer. She received hydromorphone in the ED, and is urgently taken to the operating room. Postoperatively, she is on a patient-controlled analgesic (PCA) pump containing fentanyl. Her last dose of buprenorphine-naloxone was 20 h prior to the surgery; her daily dose is 16 mg.
