Gauze rolls are made from layers of cotton and can be used as a primary or secondary dressing. As a primary dressing, gauze wraps can dress minor wounds or can be placed on top of an antibotic ointment. If you're using gauze rolls as a primary dressing, it is best to choose a sterile wrap. The sterile rolls are individually packaged to protect them from contaminants. Sterile gauze is recommended if it will be directly touching a wound. Non-sterile gauze is suitable to use as a secondary dressing. This type of gauze roll is often used to hold wound dressings in place and to support injured body parts. It can also absorb any fluid that seeps through the primary dressing. Non-sterile bandage rolls can easily be wrapped around arms, legs, and the torso and secured in place with medical tape. You can wrap the gauze slightly tighter to apply light compression to an area if needed. Express Medical Supply offers gauze wraps in varying widths to best suit the body part you are dressing. For example, dressing a finger would be best done with a more narrow gauze roll. A wider gauze roll would be ideal for wrapping an ankle, arm, or abdomen. Gauze bandage rolls are a staple product to include in first aid kits.
