Although a person cannot feel pain after receiving a local anesthetic, they may still feel some pressure or movement. Since intravenous anesthetics produce different effects to inhaled anesthetics, scientists suspect that the two types of drugs target different sets of proteins.ĭoctors use local anesthesia to numb a specific area of the body. Most experts now agree that the drugs work by targeting proteins in the membranes surrounding nerve cells. Until recently, experts knew very little about how anesthetics worked. Local and regional anesthetics numb the part of the body that requires numbing, allowing the patient to stay awake during the procedure.ĭoctors may administer anesthetics via the following, depending on the type of anesthetic and the type of medical procedure:.General anesthetics put a person into a state of controlled unconsciousness so that they do not experience pain during the procedure and do not know what is happening.There are four main types of anesthetic: general, local, regional, and sedative.
