Inhalational anesthetics are a group of medications used to induce and maintain general anesthesia during surgical procedures. They are delivered through a vaporizer and inhaled by the patient, allowing for rapid onset and control of anesthesia levels. Common examples include nitrous oxide, isoflurane, and sevoflurane. These anesthetics work by affecting the central nervous system, leading to a loss of consciousness and sensation. They are often preferred for their ease of use and ability to be quickly adjusted or discontinued, making them suitable for various surgical settings. Safety monitoring is essential to manage potential side effects.
