Desmurgy is a branch of surgery related to dressings and bandages. Bandages are an integral part of first aid and are used for wounds, bleeding, and immobilizing fractures. Common bandages include triangular bandages, bandages with rubber adhesive, and elastic bandages. Proper bandage application involves using a larger bandage size than the wound and securing it properly. Common bandage types are triangular, circular, spiral wrap, and figure eight bandages. Each has specific uses and application techniques for parts of the body. It is important to check circulation after applying a bandage.
