In regional anesthesia, a "block" refers specifically to the process of injecting anesthetic agents near nerves to interrupt the transmission of pain signals to the brain. This localized approach allows for the targeted numbness of a specific area of the body, which is particularly beneficial during surgeries or procedures that would otherwise cause pain. By blocking or inhibiting nerve impulses in a designated region, patients can remain awake or sedated while experiencing minimal discomfort, thus enhancing their overall surgical experience.

This method has distinct advantages, including reducing the need for systemic analgesics and minimizing the potential side effects associated with general anesthesia. It is important to understand that a block is not a method for inducing sleep or a type of general anesthesia, which affects the entire body, nor is it primarily designed for enhancing recovery, although effective pain management can contribute to better post-surgical outcomes.
