SKIN INJURY (CUTS, SCRAPES, BRUISES)
Injury Definition
- Cuts and Scratches: Superficial cuts (scratches) only extend partially through the skin and rarely become infected. Deep cuts (lacerations) go through the skin (dermis).
- Abrasions or Scrapes: An area of superficial skin that has been scraped off. Commonly occurs on the knees, elbows and palms.
- Bruises: Bruises (contusions) result from a direct blow or a crushing injury; there is bleeding into the skin from damaged blood vessels without an overlying cut or abrasion.
When are Stitches Needed?
- Any cut that is split open or gaping probably needs sutures (stitches). Cuts longer than 1/2 inch (12 mm) usually need sutures. On the face, cuts longer than ΒΌ inch (6 mm) usually need sutures.
- A physician should evaluate any open wound that may need sutures regardless of the time that has passed since the initial injury.
Tetanus Booster
- Tetanus is a rare infection caused by bacteria that are found in many places, especially in dirt and soil. The tetanus bacteria enter through a break in the skin and then spread through the body.
- Tetanus is commonly called "lock jaw" because the first symptom is a tightening of the muscles of the face. However, the final stage of the infection is much more serious. All of the muscles of the body go into severe spasm, including the muscles that control breathing. Eventually a person with a tetanus infection loses the ability to breath, and may die in spite of intensive treatment in the hospital.
- A tetanus booster protects you from getting a tetanus infection. It does not prevent other kinds of wound infection.
- Clean Cuts and Scrapes - Booster Needed Every 10 Years: Patients with clean MINOR wounds AND who have previously had 3 or more tetanus shots (full series), need a booster every 10 years. Examples of minor wounds include a superficial abrasion or a cut sustained while washing dishes. Obtain booster within 72 hours.
- Dirty Cuts and Scrapes - Booster Needed Every 5 Years: Patients with dirty wounds need a booster every 5 years. Examples of dirty wounds include those contaminated with soil, feces, saliva and more serious wounds from deep punctures, crushing, and burns. Obtain booster within 24. When in doubt? assume that it is a dirty wound.
