Activity Description

Inhaled anesthetic agents are widely used in clinical practice to induce and maintain general anesthesia during surgical procedures. Common agents include halothane, sevoflurane, desflurane, isoflurane, enflurane, and nitrous oxide, each with distinct pharmacodynamic and pharmacokinetic properties. These agents exert dose-dependent cardiovascular effects, such as fluctuations in systemic vascular resistance, myocardial contractility, and mean arterial pressure, which may contribute to hemodynamic instability, particularly in patients with preexisting cardiovascular disease.

Potential complications of inhaled anesthetics include prolonged QT interval and increased intraocular pressure. Compared to intravenous anesthetics, inhaled agents offer precise control over the depth of anesthesia and rapid elimination, facilitating smoother emergence. However, these agents may also lead to airway irritation and require specialized equipment for administration. Ensuring patient safety involves careful preoperative assessment, vigilant intraoperative monitoring, and individualized anesthetic planning based on patient-specific factors.

Interprofessional communication among anesthesiologists, surgeons, and perioperative staff is crucial for optimizing outcomes and preventing adverse cardiovascular events. Research continues to explore the role of inhaled anesthetics in modern anesthesia practice, balancing their benefits and risks across diverse patient populations.

This activity for healthcare professionals is designed to enhance learners' proficiency in evaluating patient suitability for inhaled anesthetic use and managing the risks of these agents when administered perioperatively. Participants deepen their understanding of the cardiovascular effects of inhaled anesthetic agents, factors influencing hemodynamic stability, and implications for patient safety. Through this activity, learners develop strategies to optimize anesthetic selection and reduce perioperative complications. Enhanced skills empower clinicians to collaborate more effectively within an interprofessional team caring for patients receiving inhalational anesthesia.


Target Audience

This activity has been designed to meet the educational needs of physicians, physician associates, nurses, pharmacists, and nurse practitioners.

Learning Objectives

At the conclusion of this activity, the learner will be better able to:

  • Identify patients who may benefit from inhaled anesthetics based on clinical history, diagnostic results, and surgical requirements.

  • Determine the appropriate inhaled anesthetic agents and their optimal concentration, flow rate, and delivery techniques for patients requiring anesthesia.

  • Implement personalized anesthetic management approaches that integrate dynamic dose adjustments, vigilant monitoring, and timely interventions to mitigate cardiovascular risks in patients receiving inhalational anesthesia.

  • Apply effective strategies to improve care coordination among interprofessional team members to facilitate positive outcomes for patients undergoing inhalational anesthesia.
