Regional anesthesia results when anesthetic drugs are injected near a group of specific nerves, numbing a larger area than a local anesthetic. Regional anesthesia is best practiced in the context of a standardized anesthetic and surgical protocols; these plans are generally referred to as anesthetic pathways. 8 Aiming for a complete picture, they collected input data on anesthetic consumables, gases and drugs, and electricity for patient warming and the The two major local anesthetics used in veterinary medicine are lidocaine and bupivacaine. It reduces the number of medications required to induce and maintain general anesthesia, avoids insertion of an airway device, and decreases mortality and morbidity.
