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

Over the past several decades, multiple studies and clinical practice have demonstrated the cardiovascular effects of inhalation anesthetic agents. Early anesthetics included diethyl ether and nitrous oxide, whereas more recent halogenated agents include isoflurane, desflurane, and sevoflurane. Halogenated agents produce similar circulatory effects in young, healthy individuals during maintenance anesthesia.[1] However, comorbidities, extremes of age, concurrent medications, and additional factors can alter the expected effects. The development of the anesthetic care team approach underscores the importance of effective communication to improve outcomes. A significant cardiovascular effect of inhalation anesthetic agents is their impact on components of cardiac output, which can lead to reductions in blood pressure. Lowering blood pressure may benefit certain patients, such as those with hypertension, but it may also pose risks for individuals with hypotension or those predisposed to hemodynamic instability. To counteract these effects, anesthesiologists may administer medications to support blood pressure or cardiac output while closely monitoring the patient throughout the procedure. Inhalation anesthetics can alter heart rate and rhythm. These changes may result from the direct effects of the anesthetic on the heart and contributing factors such as cardiac output fluctuations. Inhalation anesthetic agents likewise influence the respiratory system by altering breathing rate and depth. These changes can affect oxygen and carbon dioxide levels in the blood, potentially impacting cardiovascular function. The cardioprotective effects of volatile anesthetics and certain intravenous anesthetics have been well-documented in preclinical studies, but their clinical efficacy remains uncertain. Translating these insights into clinical practice presents ongoing challenges due to the complexity of underlying mechanisms and variability in patient response. Several recent clinical trials have investigated the cardioprotective effects of anesthetics over the past 5 years. Studies have produced mixed findings regarding the clinical relevance of volatile anesthetics for cardioprotection. Guidelines have evolved, with some endorsing the use of volatile anesthetics for cardioprotection in noncardiac surgeries or coronary artery bypass graft surgery, whereas others do not support their use.

Studies have produced mixed findings regarding the clinical relevance of volatile anesthetics for cardioprotection. Guidelines have evolved, with some endorsing the use of volatile anesthetics for cardioprotection in noncardiac surgeries or coronary artery bypass graft surgery, whereas others do not support their use. Clinical trials have evaluated multiple anesthetic techniques, including volatile, intravenous, and xenon gas anesthetics. Some studies have found no differences in clinical outcomes between volatile and intravenous anesthetics, whereas others have reported biomarker improvements that did not translate into clinical benefits. Meta-analyses have consistently shown reductions in morbidity or mortality with volatile anesthetics compared to total intravenous anesthesia. Xenon gas has also been explored as a cardioprotective agent, but its clinical advantages over other anesthetics remain uncertain.[2]

The evolution of anesthetic care teams underscores the importance of open communication among interprofessional healthcare team members throughout the preoperative, intraoperative, and postoperative periods. Collaborative selection of the anesthetic modality before surgery on a case-by-case basis contributes to better patient outcomes. Maintaining flexibility during the intraoperative period requires clear and continuous communication within the anesthetic care team to adapt to changing conditions. Postoperative case reviews further enhance future outcomes by facilitating continuous improvement. Effective communication among anesthesiologists, nurse anesthetists, surgeons, and recovery room nurses fosters a cohesive approach, optimizing patient safety and reducing the risk of adverse cardiac events associated with anesthetic agents. Skills Understanding the cardiovascular effects of inhaled anesthetic agents is critical in the perioperative setting. Effective perioperative management requires collaboration among interprofessional team members. The choice of inhaled anesthetic agents and the selection of a specific agent should consider patient-specific factors, surgical considerations, and perioperative circumstances. Strategy Maintaining continuous, closed-loop communication within the perioperative care team ensures appropriate decision-making regarding the use of inhaled anesthetic agents. Clear communication about the selected technique and potential management concerns enhances patient safety and facilitates coordinated care. Ethics Before inducing anesthesia, comprehensive informed consent must be obtained from either the patient or, when the patient lacks capacity, an authorized decision-maker. All team members should feel empowered to express any concerns to the team or the patient, ensuring stakeholder buy-in while providing additional layers of review and early identification of potential issues. Responsibilities All team members must communicate responsibilities, concerns, and actions with colleagues throughout the perioperative period. Timely and transparent communication ensures coordinated and efficient patient care. Interprofessional Communication A respectful exchange of information and concerns among team members is essential. The perioperative environment should promote open dialogue without fostering hostility or intimidation. Care Coordination
