Perioperative Management of Patients on Buprenorphine and Methadone: A Narrative Review.

: The opioid epidemic has been a major health and social problem over the last few decades. An increasing number of patients with Opioid Use Disorder (OUD) are presenting for perioperative management. These patients are either on buprenorphine or methadone for the maintenance and treatment of opioid addiction or chronic pain. In settings of acute pain, optimal management of patients with OUD is challenging and recovery can be jeopardized secondary to the unique pharmacology of these agents. This narrative review aims to summarize existing studies on the perioperative management of patients using buprenorphine and methadone and provide guidance to the management of patients with OUD during the perioperative period.
