Anesthesia is a term that refers to the use of drugs to alleviate pain during surgery and other treatments. Anesthetics are the name for these medications. Injections, inhalation, topical lotions, sprays, eye drops, and skin patches are all options. They lead you to lose your ability to feel or be conscious. In small treatments, such as filling a cavity, anesthesia may be employed. It could be utilized during births or colonoscopies, for example. It's also employed in both small and big procedures. An anesthetic may be administered by a dentist, nurse, or doctor in some instances. In some circumstances, an anesthesiologist may be required. An anesthesiologist is a doctor who specializes in administering anesthesia. When emergency conditions are not effectively treated, general anesthesia can cause physiological responses that can lead to morbidity and mortality. As a result, it is considered a high-risk activity in which the advantages of surgery must outweigh the risks
