– Animal and human bites
– Puncture wounds
– Ragged, large, or deep wounds
– Visible bone, joint, muscle, fat, or tendon
– Wound entering joint or body cavity
– “Fight bite”
12. • Wounds needing sutures
– Best placed within 6 to 8 hours
• Anyone who has not had a tetanus

• Avulsions most often involve ears, fingers,
and hands.
– Can bleed heavily
21. Avulsions: What to Do
• Gently move the skin back to normal
position.
• Cover with sterile or clean dressing and
apply pressure.
• If bleeding continues, apply tourniquet or
hemostatic dressing, if available.
23. Blisters: What to Do
• Hot spot
– Relieve pressure by applying:
• Blister bandage
• Surgical tape
• Elastic tape
– Trim and round edges of tape.
• Blister that is closed and not very painful
– Use the most appropriate method discussed.
25. Blisters: What to Do
• Blister that is closed and very painful
(cont’d)
