This technique can be used for procedures such as digit amputation. A tourniquet is placed around the limb, and local is injected into a vein such that it can flow around the region but not systemically as blood flow of the foot is occluded. Once the procedure has finished, the tourniquet should be removed slowly to prevent systemic effects of the agent. | This technique can be used for procedures such as digit amputation.
