Perioperative Management of Buprenorphine: Solving the Conundrum.

OBJECTIVE: There is no consensus on the optimal perioperative management of patients on buprenorphine (BUP) for opioid use disorder (OUD). This article will review the available literature on BUP and the analgesic efficacy of BUP combined with full mu-opioid agonists and discuss the conflicting management strategies in the context of acute pain and our institution's protocol for the periprocedural management of BUP. METHODS: We searched published data on BUP periprocedural management from inception through March 2018 without language restrictions. Study selection included publications reporting outcomes on perioperative pain management in OUD patients maintained on BUP. RESULTS: Our search resulted in four case reports supporting periprocedural discontinuation of BUP and two case series, one secondary observational study, one prospective matched cohort study, and four retrospective cohort studies supporting periprocedural continuation of BUP. No clinical trials were identified. CONCLUSIONS: Maintaining BUP perioperatively does not lead to worsened clinical outcomes. Patients can receive adequate pain control from mu-opioid agonists while maintained on BUP. Based upon available evidence, we recommend continuing BUP at a reduced dose when indicated to avoid withdrawal symptoms and to facilitate the analgesic efficacy of mu-opioid agonists administered in combination for acute postoperative pain.

Opioid Use Disorders: Perioperative Management of a Special Population.

Opioid-related overdose deaths have reached epidemic levels within the last decade. The efforts to prevent, identify, and treat opioid use disorders (OUDs) mostly focus on the outpatient setting. Despite their frequent overrepresentation, less is known about the inpatient management of patients with OUDs. Specifically, the perioperative phase is a very vulnerable time for patients with OUDs, and little has been studied on the optimal management of acute pain in these patients. The preoperative evaluation should aim to identify those with OUDs and assess factors that may interfere with OUD treatment and pain management. Efforts should be made to provide education and assistance to patients and their support systems. For those who are actively struggling with opioid use, the perioperative phase can be an opportunity for engagement and to initiate treatment. Buprenorphine, methadone, and naltrexone medication treatment for OUD and opioid tolerance complicate perioperative pain management. A multidisciplinary team approach is crucial to provide clinically balanced pain relief without jeopardizing the patient's recovery. This article reviews the existing literature on the perioperative management of patients with OUDs and provides clinical suggestions for the optimal care of this patient population.
