ncontrolled and indiscriminate prescribing of opioids during the past 3 decades has led to an opioid crisis that started in North America and spread throughout high-income countries. [1][2][3][4][5] This crisis initially drew attention to inappropriate prescribing of opioids for the management of chronic noncancer pain. 3 This is pain that persists for more than 3 months, is not associated with tissue damage but rather a dysfunctional pain system, and for which opioids are not recommended. 5,6 In contrast, opioids remain an effective and important component of the management of acute postoperative pain, although it has recently become clear that excessive or prolonged prescribing of opioids for postoperative pain relief, both in hospital and after discharge, may also be playing a role in the crisis and increasing patient harms. 5 The genesis of this crisis is exemplified by the title of a 2018 article, "Good Intentions Gone Bad, an Industry Gone Rogue, and Watch Dogs Gone to Sleep." 2 The aim of this narrative review was to explore some of the current issues surrounding the use of opioids in the perioperative period, including the drivers that led to escalation of use; the resultant in-crease in patient harms, including opioid-induced ventilatory impairment (OIVI); the move away from using self-reported pain scores alone to assess adequacy of analgesia or to guide titration of opioids; concerns about the routine use of long-acting opioids including controlledrelease (also known as slow-, extended-, modified-, or sustainedrelease) formulations for the management of acute pain; and concerns about prescription of opioids on discharge from hospital.

Finally, this review addresses whether opioid-free anesthesia and analgesia (OFAA) might have a role to play in reducing postoperative opioid-related harms.

The aim of this narrative review was to explore some of the current issues surrounding the use of opioids in the perioperative period, focusing on drivers that led to escalation of use, patient harms, the move away from using self-reported pain scores alone to assess adequacy of analgesia, concerns about the routine use of controlled-release opioids for the management of acute pain, opioid-free anesthesia and analgesia, and prescription of opioids on discharge from hospital.OBSERVATIONS The origins of the opioid crisis are multifactorial and may include good intentions to keep patients pain free in the postoperative period. Assessment of patient function may be better than unidimensional numerical pain scores to help guide postoperative analgesia. Immediate-release opi...
