The use of vasopressor supplement materials to local anesthetics is commonly used in procedures in various fields of dentistry, ENT (ear, nose, and throat), Plastic Surgery, Hand surgery and gastroenterology. Epinephrine is used to constrict small blood vessels, thus reducing bleeding during a medical procedure, reducing the toxicity by reducing systemic absorption of local anesthetic, and prolonging the duration and intensity of neural blockage created by the local anesthetic.
