Opioid use disorder and misuse: A review of the epidemiology and medical implications for pediatric anesthesiologists

Summary

This educational review presents an overview of opioid use disorder, misuse and overdose among adolescents, and the clinical implications for anesthesiologists. It provides definitions, discusses the epidemiology worldwide, (focusing on North America), and emphasizes the clinical implications of patients with chronic opioid exposure, including perioperative pain management, as well as opioid overdose and prolonged use of opioids after acute exposure. In the USA, opioid use disorder and negative outcomes related to opioids rose dramatically from 1999-2010; concomitantly heroin use and fatal overdoses have increased as heroin use is associated with the disordered use of licit opioids. Among adolescents and young adults, opioid use disorder is significant, with continued increases in disordered use specifically among young adults. Acute opioid intoxication may have multiple medical implications in addition to respiratory depression, and children are susceptible to acute intoxication via accidental ingestion of prescription opioids. Novel opioid formulations, such as acetyl fentanyl, with unpredictable pharmacology may also be present in acute intoxication. Chronically, opioid use presents challenges for safe and adequate pain management, in the presence of opioid-induced hyperalgesia and differential tolerance as well as mental health issues including depression and anxiety. Predictors of prolonged opioid use in adolescents and adults after surgery is an area of ongoing research. Young patients encountered by pediatric anesthesiologists may be involved in diversion and disordered use of opioids. Increased awareness among anesthesiologists is important, as perioperative discussions often provide an opportunity to detect at risk patients.
