Which technique involves injecting a local anesthetic under the skin near a nerve?

The technique of injecting a local anesthetic under the skin near a nerve is known as infiltration anesthesia. This method involves administering the anesthetic solution directly into the tissues surrounding a surgical site or area of pain. By doing so, the local anesthetic diffuses into the surrounding tissues and affects the sensory nerves in that particular area, providing pain relief during procedures.

Infiltration anesthesia is commonly used in various veterinary procedures because it allows for targeted pain control with minimal systemic effects. It is particularly effective for minor surgeries or procedures where more extensive regional anesthesia is not necessary.

Other techniques mentioned, such as intraarticular anesthesia, splash block, and epidural anesthesia, carry out different actions and are suited for different types of pain management and surgical interventions. Intraarticular anesthesia specifically refers to injecting anesthetics directly into a joint, while a splash block involves applying local anesthetic to a surgical site for surface-level anesthesia. Epidural anesthesia targets the epidural space surrounding the spinal cord to provide analgesia to larger areas of the body. Each of these methods has unique applications that differ from the localized approach of infiltration anesthesia.
