Isoflurane is a type of inhalation anesthetic commonly used during surgeries to induce and maintain general anesthesia. It is a colorless, volatile liquid that is vaporized and inhaled by patients. Isoflurane works by depressing the central nervous system, leading to a loss of consciousness and sensation, allowing surgical procedures to be performed without pain or awareness. This anesthetic is favored for its rapid onset and recovery times, making it suitable for various surgical procedures. It is often used in combination with other medications to enhance its effects and ensure patient safety. Isoflurane is typically administered using specialized equipment, such as an anesthesia machine.
