The administration of anesthetic agents is a critical aspect of perioperative care, ensuring patient comfort and safety during surgical procedures. Best practices in this domain encompass a range of considerations, including drug selection, dosing strategies, monitoring techniques, and patient-specific factors. By adhering to established guidelines and leveraging evidence-based practices, anesthesia providers can optimize the efficacy of anesthetic agents while minimizing the risk of adverse events, ultimately enhancing patient outcomes and satisfaction [1].

One of the first considerations in administering anesthetic agents is the selection of appropriate drugs based on the type of surgery, patient characteristics, and desired anesthetic goals. General anesthetics, such as inhalational agents and intravenous (IV) agents, are commonly used to induce and maintain unconsciousness during surgery. Inhalational agents like sevoflurane and desflurane offer rapid onset and offset of action, making them suitable for a variety of surgical procedures. IV agents such as propofol and etomidate are preferred for their quick induction and smooth emergence from anesthesia [2].

In addition to general anesthetics, adjunctive agents such as opioids, benzodiazepines, and muscle relaxants may be used to enhance anesthesia and provide analgesia, sedation, and muscle relaxation as needed. Local anesthetics, administered via infiltration, nerve block, or epidural/spinal routes, can complement general anesthesia or serve as the primary anesthetic for certain procedures, offering targeted pain relief and minimizing systemic side effects [3].

Once the appropriate anesthetic agents have been selected, the next step is determining the optimal dosage and titration strategy for each patient. Factors influencing drug dosing include patient age, weight, comorbidities, concurrent medications, and pharmacogenetics. Pharmacokinetic and pharmacodynamic modeling, along with real-time monitoring of vital signs and anesthesia depth, help guide dosing decisions and titration to achieve the desired level of anesthesia while minimizing the risk of under- or overdosing [4].

Target-controlled infusion (TCI) systems, which calculate and adjust drug infusion rates based on patient-specific pharmacokinetic parameters, offer a precise and automated approach to anesthesia delivery, particularly for IV agents like propofol and remifentanil. Closed-loop anesthesia delivery systems, incorporating feedback from patient monitors to adjust drug administration in real time, further enhance the accuracy and safety of anesthesia titration, reducing the workload on anesthesia providers and optimizing patient care [5].

Continuous monitoring of vital signs, including heart rate, blood pressure, respiratory rate, and oxygen saturation, is essential during anesthesia administration to detect and address changes in patient status promptly. Advanced monitoring techniques, such as electrocardiography (ECG), pulse oximetry, capnography, and bispectral index (BIS) monitoring, provide valuable insights into cardiovascular function, respiratory status, and depth of anesthesia, guiding clinical decision-making and ensuring patient safety throughout the perioperative period [6].

In addition to physiological monitoring, vigilant assessment of anesthesia depth and awareness is critical to prevent intraoperative awareness and recall, a rare but potentially distressing complication of anesthesia. Objective measures of anesthesia depth, such as BIS monitoring and entropy monitoring, complement subjective assessments based on clinical signs and responses to surgical stimuli, enabling anesthesia providers to maintain an appropriate level of unconsciousness while minimizing the risk of awareness [7].

Anesthesia administration must be tailored to the individual patient's needs, taking into account factors such as medical history, allergies, airway anatomy, and pre-existing conditions that may impact drug metabolism, distribution, or response. Special populations, including pediatric patients, elderly patients, pregnant patients, and those with obesity or organ dysfunction, require particular attention to optimize anesthesia efficacy and safety while mitigating potential risks and complications [8].

Effective communication and collaboration among members of the perioperative team are essential to ensure the safe and efficient administration of anesthetic agents. Anesthesia providers must liaise closely with surgeons, nurses, and other healthcare professionals to coordinate care, anticipate challenges, and respond promptly to emergent situations during surgery. Clear communication of the anesthetic plan, drug choices, dosages, and expected outcomes fosters teamwork, reduces errors, and promotes optimal patient outcomes [9, 10].


Best practices in the administration and efficacy of anesthetic agents encompass a comprehensive approach to perioperative care, integrating evidence-based principles, advanced monitoring technologies, and patient-centered strategies to optimize anesthesia delivery and enhance patient safety and satisfaction. By adhering to established guidelines, leveraging innovative techniques, and fostering interdisciplinary collaboration, anesthesia providers can uphold the highest standards of care and contribute to successful surgical outcomes for patients undergoing anesthesia.
