When applying dressing, you must remember the following basic rules:

• Use sterile or very clean materials as dressings. Avoid touching the part/s of the dressing that will directly come into contact with the wound. If possible, wash your hands with soap and water before handling the dressing but this should not delay providing emergency care. If using pre-packed dressings, grasp it from the corner of the protective pack and place over the wound.
• Cover the entire wound and its immediate surrounding areas.
• Control bleeding. Before applying bandage, make sure the dressing has effectively controlled the bleeding. Continue to apply dressing and manual pressure until bleeding has stopped.
• Do not remove dressing once it has been applied to a wound. Removing the dressing may restart bleeding and even injure surrounding tissues. If bleeding continues, put new dressings on top of the blood-soaked dressings.
• However, if bleeding persists despite bulky dressing, the bulky blood-soaked dressings may be removed to allow reestablishing of pressure.

Basic rules for use of bandage

Bandage is any material that is used to hold the dressing in place and provides pressure to the wound. Unlike dressings, bandages may not be sterile.

When applying bandage, you must remember the following basic rules:

• Not too tight but not too loose. All dressings must be held snugly in place, but the bandage should not be too constricting that it restricts blood flow to the affected part. The bandage should hold the dressing snugly so that it does not slip or move around the wound.
• Do not leave loose ends as they can get caught on objects when the victim moves. Common loose ends include that of tape, gauze and cloth.
• Leave the tips of fingers and toes uncovered. The fingers and toes must be exposed, if possible, to observe changes in skin color that may indicate possible problems with circulation, as well as to allow easier neurologic assessment. Pale, pain or bluish-colored skin all indicate too tight bandage. However, if the digits are burned, they should be covered.
• Cover all edges of the dressing to reduce possible contamination.
• It is best to apply bandage to a large area of the extremity to ensure uniform pressure.
