Due to their size and anatomy, cattle are not very good candidates for general anaesthesia meaning that many procedures performed use local techniques. Most surgeries performed on these patients can be done standing with a small amount of sedation and regional and local nerve blocks. Local techniques are also used in cattle for procedures such as castration and dehorning.

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.
