Beta-adrenergic agonists and antagonists.

Contemporary Anesthesia Practice

|January 1, 1983

Summary

This summary is machine-generated.

Beta adrenergic antagonists like propranolol are crucial for managing tachycardia and in balanced anesthesia, especially for coronary artery disease patients. Newer agents offer future potential, but current focus is on mastering existing drugs and hemodynamic evaluation.

Background:

Beta adrenergic antagonists are a diverse class of drugs.
Newer agents present opportunities for nuanced therapeutic applications.
Current clinical focus remains on established agents and their optimal use.

Purpose of the Study:

To highlight the current clinical applications of beta-blockers in anesthesia.
To emphasize the importance of hemodynamic evaluation in drug utilization.
To introduce newer beta-agonist agents like dopamine and dobutamine.

Main Methods:

Clinical experience with propranolol for tachycardia control.
Integration of beta-blockade in balanced anesthesia protocols.
Hemodynamic monitoring for precise drug administration.

Comparison of beta-agonist agents, including dopamine and dobutamine.

Main Results:

Propranolol is essential for managing intraoperative and postoperative tachycardia.
Beta-blockade serves as adjunctive therapy with vasodilators.
Beta-blockade is valuable in balanced anesthesia for patients with coronary artery disease.
Dopamine may enhance renal blood flow via dopaminergic stimulation in adults.

Conclusions:

Extensive experience with propranolol is necessary for effective hemodynamic management.
Sophisticated hemodynamic evaluation guides the optimal use of beta-blockers.
Dopamine's unique renal effects differentiate it among beta-agonists.
