'''Intravenous regional anaesthesia''' is used commonly for surgeries affecting the distal limb, particularly cattle. It requires the use of a tourniquet to minimise blood flow from the distal limb, so that the anaesthetic agent only affects the tissue distal to the tourniquet. The agent is injected into a small vein, allowing for diffusion of the agent throughout the circulation distal to the tourniquet. Once the procedure has finished, it is imperative the tourniquet is removed slowly to avoid systemic effects of the anaesthetic agents used.
