Intravenous Regional Anesthesia (Bier Blocks)

Intravenous Regional Anesthesia, commonly known as a Bier block, is a method used to numb a specific arm or leg during surgery or medical procedures. A healthcare provider places a tourniquet around the limb to restrict blood flow, then injects a local anesthetic into a vein. This numbs the area without affecting the whole body, allowing the patient to remain awake and comfortable while the procedure is done. It's a safe and effective way to manage pain in a targeted area, particularly for surgeries involving the extremities.
