Skinned Arm (Abrasion) First Aid: Step‑by‑Step Wound Care

How to Treat a Skin Abrasion on the Arm

A “skinned” arm is a superficial abrasion. Proper care prevents infection and minimizes scarring.

Step‑by‑Step

1. Control bleeding: Direct pressure with clean gauze/cloth 5‑10 min.
2. Wash hands thoroughly (soap, water, 20 sec).
3. Irrigate: Cool running water 2‑3 min to remove debris. No harsh soaps, hydrogen peroxide, iodine, alcohol—they damage tissue.
4. Gentle cleanse: Mild soap around wound; rinse well.
5. Pat dry: Sterile gauze/clean cloth. No rubbing.
6. Antibiotic ointment: Thin layer (bacitracin, polysporin) – reduces infection, keeps moist.
7. Cover: Non‑stick sterile pad (Telfa) + rolled gauze or adhesive border dressing. Not too tight.
8. Change daily or when wet/soiled. Re‑apply ointment.
9. Monitor for infection: Increasing pain, spreading redness, warmth, pus, red streaks, fever → see clinician.
10. Tetanus: Booster if >5 yrs (dirty wound) or >10 yrs (clean).
11. Elevate arm to reduce swelling.
12. Sun protection on healed skin (SPF 30+) for 12+ months to prevent hyperpigmentation.
