Volatile anesthetics are a class of anesthetic agents that exist in a gaseous state at room temperature. They are commonly used during surgical procedures to induce and maintain general anesthesia. These agents are inhaled and absorbed into the bloodstream, allowing for rapid onset and recovery. Examples include isoflurane, sevoflurane, and desflurane. These anesthetics work by altering the activity of neurotransmitters in the brain, leading to a reversible loss of consciousness and sensation. Their effects can be monitored and adjusted during surgery, making them a preferred choice for many anesthesiologists. Safety and effectiveness are key considerations when using volatile anesthetics.
