what is the local anaesthetic used by dentists
Dental anesthesia The most commonly used local anesthetic is lidocaine (also called xylocaine or lignocaine), a modern replacement for procaine (also known as novocaine). Its half-life in the body is about 1.5â€“2 hours. Other local anesthetic agents in current use include articaine (also called septocaine or ubistesin), bupivacaine (a long-acting anesthetic), Prilocaine (also called Citanest), and mepivacaine (also called Carbocaine or Polocaine). A combination of these may be used depending on the situation. Also, most agents come in two forms: with and without epinephrine (adrenaline) or other vasoconstrictor that allow the agent to last longer and also controls bleeding in the tissue during procedures. Usually the case is classified using the ASA Physical Status Classification System before any anesthesia is given.
American Society of Anesthesiologists In 1905, nine physicians (from Long Island, N.Y.) organized the first professional anesthesia society. In 1911, the Society expanded to 23 members and became the New York Society of Anesthetists. Over the next 25 years, involvement in anesthesia-related issues grew and attracted other interested physicians nationwide. In 1936, the Society changed its name to the American Society of Anesthetists. In 1945, the organization moved to become the American Society of Anesthesiologists (ASA). In 1960, the ASA established an Executive Office in Park Ridge, Illinois to meet growing membership and patient-care demands. In 2014, the ASA opened new headquarters in Schaumburg, Illinois.[1]
