IV regional anesthesia
IV regional anesthesia, also known as Bier block, is a technique used to numb a specific area of the body, typically an arm or leg, during surgical procedures. This method involves injecting an anesthetic medication directly into a vein, while a tourniquet temporarily restricts blood flow to keep the anesthetic localized. The patient remains awake but does not feel pain in the treated area. It's often used for minor surgeries because it allows for effective pain relief without needing full general anesthesia, which affects the entire body.
