Trauma dressing are a type of bandage that is specifically designed to provide wound coverage for large or deep wounds. They are usually made of a soft material, such as gauze, that will not stick to the wound and can absorb a large amount of blood.  They are essential components of a first aid kit as they are helpful for controlling bleeding, covering and protecting wounds from additional contamination and reducing the risk of infection.

Trauma dressings are often used in conjunction with other types of medical supplies, such as tourniquets and pressure bandages. When used together, these products can effectively control bleeding and reduce the risk of further injury.
