Dexmedetomidine as an adjunctive analgaesic in the perioperative setting: A review of the literature.

Though arguably past the initial phase of the opioid epidemic, opioid-sparing or opioid-eliminating pain management regimens remain beneficial for patients and practitioners alike. Providing adequate analgaesia without relying on opioids is especially advantageous in the operative setting, as patients may be able to recover without deep levels of sedation or the need for a high amount of opioid medications. Despite being used primarily as a sedative over the past 20 years, dexmedetomidine, a centrally acting alpha2-agonist, possesses analgaesic properties, though its use has been limited by its well-described cardiovascular suppressive effects. The objective of this review was to determine the efficacy and safety of adjunctive dexmedetomidine for the purposes of analgaesia in the perioperative setting.
