Dexmedetomidine, a selective alpha2-adrenoceptor agonist, offers sedation, analgesia, and anxiolysis with minimal respiratory depression. Its off-label perioperative use shows promise, but further research is needed to define its role in anesthesia practice.

Area of Science:

  • Pharmacology
  • Anesthesiology

Background:

  • Dexmedetomidine is a potent and selective alpha2-adrenoceptor agonist.
  • Its development has renewed interest in alpha2-adrenoceptor agonists for perioperative applications.

Purpose of the Study:

  • To review the usefulness of dexmedetomidine in anesthesia practice.
  • To discuss recent knowledge and experience with dexmedetomidine in perioperative settings.

Main Methods:

  • Review of recently acquired knowledge and experience with dexmedetomidine.
  • Discussion in the context of known pharmacological properties.

Main Results:

  • Dexmedetomidine provides dose-dependent sedation, analgesia, sympatholysis, and anxiolysis.
  • It exhibits minimal respiratory depression, with predictable side-effects.

  • Unique sedative properties suggest promising perioperative applications.

    • Conclusions:

    • Dexmedetomidine possesses beneficial pharmacological properties for anesthesia.
    • Its use in anesthesia practice is currently off-label, despite ICU approval.
    • Further studies are required to establish its definitive role in the perioperative period.
