Alpha2-adrenoceptor agonists offer significant perioperative benefits, including improved hemodynamic stability and reduced anesthetic needs. These agents also provide analgesia and may help prevent perioperative myocardial ischemia.

Area of Science:

  • Anesthesiology
  • Pharmacology
  • Cardiology

Background:

  • Alpha2-adrenoceptor agonists possess valuable properties for perioperative management.
  • These agents can mitigate the physiological stress associated with intubation and surgery.

Purpose of the Study:

  • To review the beneficial actions of alpha2-adrenoceptor agonists in the perioperative period.
  • To highlight their role in hemodynamic stability, anesthetic/opioid reduction, and myocardial ischemia prophylaxis.

Main Methods:

  • Review of existing literature on alpha2-adrenoceptor agonists in perioperative care.
  • Focus on agents with short durations of action like dexmedetomidine and mivazerol.

Main Results:

  • Central sympatholytic action leads to improved hemodynamic stability.

  • Reduced requirements for anesthetics and opioids, alongside sedation, anxiolysis, and analgesia.
  • Potential benefits in preventing and treating perioperative myocardial ischemia.

    • Conclusions:

    • Alpha2-adrenoceptor agonists are beneficial for perioperative management, especially in high-risk patients.
    • Their analgesic effects extend to the peripheral and central nervous systems.
    • Short-acting agents are suitable for surgical patients, enhancing local anesthetic and opioid efficacy.
