The Bier block is ideally suited for management of many types of trauma to an extremity. Blood is removed from an injured extremity by elevation and wrapping, and then a pneumatic tourniquet is applied proximal to the site of injury. Lidocaine is then injected into a vein distal to the tourniquet. The tourniquet prevents entry of the lidocaine into the general circulation while anesthesia is obtained in the extremity; it also provides a bloodless surgical field.
比尔阻滞非常适合处理多种类型的肢体创伤。通过抬高和包扎从受伤肢体中排出血液，然后在损伤部位近端应用气动止血带。接着将利多卡因注入止血带远端的静脉中。在肢体获得麻醉的同时，止血带可防止利多卡因进入体循环；它还能提供无血的手术视野。
