Surgeries are major medical procedures in which a doctor attempts to correct an injury or disorder through invasive means. Due to the painful sensation of incisions, patients are put into a coma during major surgical procedures. This coma temporarily “shuts down” the patient’s body, rendering them unconscious. They are not able to feel, see, hear or remember the act of surgery.
It is the job of an anesthesiologist, a doctor that specializes in supervising anesthesia, to administer the coma-inducing drug. Anesthesia is a mixture of different gasses such as nitrous oxide, sevoflurane, ether, etc. These gasses are inhalable yet dangerous if not administered properly.
