Perioperative and Periprocedural anesthetic management of opioid tolerant patients and patients with active and medically treated opioid use disorder.

PURPOSE OF REVIEW: The increasing prevalence of opioid tolerant individuals, in combination with the expanding scope and utilization of nonoperating room anesthesia (NORA) necessitates ongoing investigation into best clinical practice for managing surgical/procedural pain in this population. The purpose of this article is to review recent guidelines, identify specific challenges, and offer considerations for managing pain in patients who are opioid tolerant secondary to opioid use disorder (OUD), with or without medications for the treatment of OUD. RECENT
FINDINGS: A comprehensive preoperative evaluation in conjunction with a multidisciplinary, multimodal pain approach is optimal. NORA adds unique situational and environmental challenges for optimizing acute on chronic pain control in tolerant individuals while maintaining safety. Direct and partial/mixed mu-agonists should typically be continued throughout the perioperative period, while mu-antagonists (naltrexone) should be held 72 h. Postprocedural discharge instructions and follow-up must be carefully arranged and ensured.
SUMMARY: Clinical recommendations continue to evolve as new consensus guidelines are published, although institution-specific guidelines are most often followed. This review focuses on most recent best practices, within NORA and operating room settings, for managing opioid tolerant patients, patients with OUD and those on medications for the treatment of OUD.
