Opioid-induced hyperalgesia (OIH) occurs when opioids paradoxically enhance the pain they are prescribed to ameliorate. To address a lack of perioperative awareness, we present an educational review of clinically relevant aspects of the disorder. Although the mechanisms of OIH are thought to primarily involve medullary descending pathways, it is likely multifactorial with several relevant therapeutic targets. We provide a suggested clinical definition and directions for clinical differentiation of OIH from other diagnoses, as this may be confusing but is germane to appropriate management. Finally, we discuss prevention including patient education and analgesic management choices. As prevention may serve as the best treatment, patient risk factors, opioid mitigation, and both pharmacologic and non-pharmacologic strategies are discussed.
Inappropriate and excessive opioid prescribing practices for treatment of chronic nonmalignant pain contributed to rising rates of opioid related mortality. Effective and widely available opioid addiction treatment resources are needed to ensure successful resolution of the “opioid epidemic”. This chapter outlines the basic pathophysiology of addiction as well as principles of opioid addiction management focusing on the pharmacological and nonpharmacological aspects of care. Pharmacological treatment focuses on opioid substitution therapy, with aim at prevention of opioid cravings and opioid withdrawal symptoms. Nonpharmacological treatment involves psychological and supportive approaches to addiction such as group meetings, psychological counseling, and mindfulness training.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
