This document categorizes and describes different types of wounds: abrasions involve damage to the outer skin layers and limited bleeding; lacerations are jagged tears of soft tissue; and punctures are small holes caused by piercing objects. It also covers treatments for blisters, calluses, and wound management, noting that immediate treatment should involve cleaning and monitoring for signs of infection such as pain, swelling, and pus formation.

1. Classification of Wounds

2.  Abrasions
 Avulsions
 Incisions
 Lacerations
 Punctures

3. Abrasions
 Outer layers of skin
damaged
 Infection can occur
 Bleeding is limited
due to rupture of
small veins and
capillaries

4. Avulsions
 Forcible separation or
tearing of tissue from
the body
 Bleeding occurs
immediately

5. Incision
 Wound with smooth
sides/edges
 Caused by sharp
object
 Severe bleeding can
exist

6. Laceration
 Jagged, irregular tear
of soft tissue

7. Punctures
 A small hole in tissue
 Object pierces the
skin
 External bleeding
limited
 Internal damage may
cause bleeding

8. Blisters
 Develop with friction
to an area
 Typical to foot or
hand
 Fluid accumulates
under the skin
 Blood vessels broken;
“blood blister” forms

9. Blister Treatment
 2 types of treatment
– Pop blister
– Cover without popping
 If blister is open,
remove as much skin
as possible and keep
covered to prevent
infection

10. Calluses
 Formed over a period
of time
 Typically on foot or
hand where bone is
right underneath skin
 Excessive formation
could be a problem

11. Wound Management
 Immediate treatment
should be taken
 Always wear
protective gloves
 Observe for signs of
infection

12. Wound Management
 Wounds involve a
compromise to the
integument (skin)
system

13. Signs of Infection
 Signs of Infection
– Pain
– Swelling
– Redness
– Heat
– Loss of function
– Fever
– Puss formation
