Anesthetists achieve precise control over inhaled anesthetic delivery by monitoring end-tidal concentrations, reducing the need for complex closed-loop systems. Modern anesthetics offer stability, ensuring a consistent anesthetic state with minimal intervention.
Area of Science:
- Anesthesiology and Pharmacology
Background:
- Anesthetics are administered for therapeutic effects, necessitating precise control to minimize side effects.
- Maintaining a stable anesthetic state is crucial for patient safety and effective treatment.
Purpose of the Study:
- To highlight the precision in controlling inhaled anesthetic concentrations.
- To discuss the role of end-tidal volatile anesthetic concentrations in anesthetic management.
- To compare manual control with closed-loop systems.
Main Methods:
- Monitoring end-tidal volatile anesthetic concentrations.
- Utilizing the low solubility of modern inhaled anesthetics.
- Comparing manual anesthetic control with processed electroencephalogram (EEG)-guided closed-loop systems.
Main Results:
- Precise control of end-tidal concentrations eliminates the need for closed-loop systems.
- Low solubility of modern anesthetics ensures stability during maintenance.
- Closed-loop systems offer a less precise alternative using processed EEG.
Conclusions:
- Manual control of inhaled anesthetics is highly precise and stable.
- Modern anesthetic properties contribute to reliable anesthetic states.
- Closed-loop systems may be less precise for volatile anesthetic delivery compared to direct monitoring.

Inhalational Anesthetics: Overview
Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
