Volatile anesthetics are a class of anesthetic drugs that are administered in gaseous or vaporized form. They are primarily used for the induction and maintenance of general anesthesia. These agents exert their effects by interacting with various targets in the central nervous system, leading to a reversible loss of consciousness, amnesia, analgesia, and muscle relaxation. The precise mechanisms of action are complex and involve modulation of ion channels and receptors in neurons.

Commonly used volatile anesthetics include sevoflurane, desflurane, isoflurane, and nitrous oxide. Each agent has distinct pharmacokinetic and pharmacodynamic properties, influencing their onset and offset of action, potency, and potential side effects. Sevoflurane is known for its rapid induction and emergence, making it suitable for outpatient procedures. Desflurane also offers quick recovery but can cause airway irritation. Isoflurane is a more traditional agent with a slower onset and offset. Nitrous oxide is a weak anesthetic but a potent analgesic, often used in combination with other agents or for brief procedures.

The administration of volatile anesthetics is typically achieved through an anesthesia machine, which vaporizes the liquid anesthetic and mixes it with oxygen and air. The concentration of the anesthetic in the inhaled gas mixture is carefully controlled by the anesthesiologist. Monitoring of vital signs, including heart rate, blood pressure, oxygen saturation, and end-tidal anesthetic concentration, is crucial to ensure patient safety. Potential risks associated with volatile anesthetics include respiratory depression, cardiovascular effects, and malignant hyperthermia in susceptible individuals.
