Summary
Alpha2-adrenoceptor agonists offer significant perioperative benefits, including improved hemodynamic stability, reduced anesthetic needs, and enhanced pain management. Their expanding clinical uses and potential for direct anesthesia induction highlight their evolving role in surgical care.
Area of Science:
- Anesthesiology
- Pharmacology
Background:
- Alpha2-adrenoceptor agonists have demonstrated expanding clinical applications.
- These agents possess valuable properties for perioperative management.
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, sedation, anxiolysis, analgesia, and myocardial ischemia management.
Main Methods:
- Review of existing literature on alpha2-adrenoceptor agonists in perioperative care.
- Analysis of their central sympatholytic effects and impact on anesthetic requirements.
Main Results:
- Alpha2-adrenoceptor agonists improve hemodynamic stability during endotracheal intubation and surgical stress.
- They reduce the need for anesthetics and opioids, providing sedation, anxiolysis, and analgesia.
- Potential benefits in perioperative myocardial ischemia prophylaxis and treatment are noted.
Conclusions:
- Alpha2-adrenoceptor agonists are versatile agents with established and growing perioperative benefits.
- New selective compounds may offer novel anesthetic administration concepts.

01:30Adrenergic Agonists: Therapeutic Uses
Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
Allergies and anaphylaxis:...

01:30Adrenergic Agonists: Direct-Acting Agents
Drugs that mimic the action of endogenous catecholamines like noradrenaline and adrenaline are called adrenergic agonists or sympathomimetics. Based on their mechanism of action, sympathomimetics can be classified as direct-, indirect-, or mixed-acting sympathomimetics. Direct-acting adrenergic agonists activate adrenoceptors without affecting presynaptic neurons, making them independent of neuronal catecholamine-depleting agents like reserpine and guanethidine.

01:31Adrenergic Receptors: ɑ Subtype
Adrenoceptors are classified into α and ꞵ classes based on their potencies to catecholamine agonists. α-adrenoceptors show the following order of catecholamine potency:
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase C—inositol-1,4,5-trisphosphate...

01:17Adrenergic Antagonists: Chemistry and Classification of ɑ-Receptor Blockers
Adrenergic antagonists, or sympatholytics, inhibit adrenoceptor activation driven by catecholamines or agonists. Based on their adrenoceptor specificity, adrenergic blockers can be categorized into two primary groups: α-adrenergic blockers (α-blockers) and β-adrenergic blockers (β-blockers). α-blockers interact with α1 and α2 subtypes of α-adrenoceptors.
Nonselective α-blockers: Nonselective α-blockers contain haloalkylamine or imidazoline moieties. Phenoxybenzamine, with a haloalkylamine...

01:18Adrenergic Agonists: Therapeutic Classification
Adrenergic agonists can be classified based on their therapeutic uses and mechanisms of action. They serve various purposes in clinical applications.
Vasopressor or pressor agents: They increase blood pressure and function as cardiac stimulants. Examples include endogenous catecholamines (norepinephrine and dopamine) and synthetic agents (phenylephrine).
Bronchodilators: β2-agonists can relax bronchial muscles and widen airways. They are commonly used for treating obstructive pulmonary...

01:24Parenteral Anesthetics: Overview
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
