IVRA (Intravenous Regional Anesthesia)

Intravenous Regional Anesthesia (IVRA), also known as Bier Block, is a technique used to numb a specific part of the body, typically an arm or leg, for surgery. A tourniquet is applied to prevent blood flow, and local anesthetic medication is injected into a vein in that limb. This numbs the area by blocking nerve signals without affecting the rest of the body. Once the procedure is complete, the tourniquet is released, allowing blood to flow back, and the anesthesia subsides. IVRA offers effective, targeted pain relief with minimal systemic effects, making it useful for certain limb surgeries.
