Isoflurane is a volatile anesthetic commonly used during surgeries to induce and maintain general anesthesia. It is administered through inhalation, allowing for rapid onset and recovery. Isoflurane works by depressing the central nervous system, leading to a loss of consciousness and sensation. This anesthetic is favored for its effectiveness and relatively low side effects compared to other agents. It is often used in both human and veterinary medicine, making it versatile for various surgical procedures. Monitoring is essential during its use to ensure patient safety and optimal anesthesia levels.
