4. Classification of Wounds
• Wounds can be classified based on various
criteria, including their cause, depth and other
characteristics. Here is a detailed classification
of wounds

5. Cont…

6. Open Wounds
• Incision: A clean, straight cut typically caused
by a sharp object.

7. Cont…
• Laceration: A jagged or irregular tear in the
skin, often caused by blunt trauma.

8. Cont…
• Abrasion: A superficial wound caused by
friction, such as a scrape or graze.

9. Cont…
• Puncture: A small, deep wound caused by a
pointed object, like a nail or needle.

10. Cont…
• Avulsion: A severe injury where a portion of
the skin and underlying tissue is torn away.

11. Closed Wounds
• Contusion: Bruising or tissue damage without
a break in the skin, caused by blunt force.

12. Based on Depth
• Superficial Wounds: Only involve the outer
layer of the skin (epidermis).

13. Cont…
• Partial Thickness Wounds: Extend into the dermis,
the second layer of skin.
• Full Thickness Wounds: Extend through the entire
thickness of the skin and may involve underlying
tissues.

14. Based on Degree of Contamination
• Clean Wounds: Caused by a sterile object with
minimal risk of infection.

15. Cont…
• Contaminated Wounds: Have foreign material
or debris, increasing the risk of infection.

16. Cont…
• Infected Wounds: Bacterial or microbial
contamination has led to an established
infection.

17. Based on Time of Onset
• Acute Wounds: Recent injuries.
• Chronic Wounds: Fail to follow the normal
healing process and persist for an extended
period.

18. Wound Healing
• Wound healing refers to a living organism's
replacement of destroyed or damaged tissue by
newly produced tissue.
• Series of events that restore integrity to a damaged
tissue

19. Cont…
• In undamaged skin, the epidermis (surface,
epithelial layer) and dermis (deeper, connective
layer) form a protective barrier against the
external environment. When the barrier is
broken, a regulated sequence of biochemical
events is set into motion to repair the
damage.

20. Phases of Wound Healing
• Inflammatory Phase
oBegins immediately after injury.
oBlood vessels constrict to control bleeding,
followed by dilation to allow immune cells to
reach the wound.
oInflammation helps remove debris and foreign
particles.

21. Cont…
• Proliferative Phase
▫ Begins a few days after the
injury and can last for several
weeks.
▫ New tissue is formed to replace
the lost or damaged tissue.
▫ Fibroblasts produce collagen to
build a framework for healing.
▫ Epithelial cells multiply to cover
the wound surface.

22. Con…
• Remodeling/ Maturation
Phase
▫ Can last for months to years,
depending on the wound's
severity.
▫ Collagen is remodeled to
increase tissue strength.
▫ Scar tissue forms, and the
wound contracts.
▫ Continues for several months
to years.

23. Factors Affecting Wound Healing
• Nutrition: Adequate
intake of vitamins
(especially vitamin C),
minerals, and protein is
crucial.

24. Factors Affecting Wound Healing
• Blood Supply: Good
circulation is necessary
for delivering oxygen and
nutrients to the wound
site.

25. Factors Affecting Wound Healing
• Infection: Infections
delay healing; proper
wound care is essential
to prevent infection.

26. Factors Affecting Wound Healing
• Age: Wound healing is generally slower in the
elderly.
• Chronic Diseases: Conditions like diabetes
and autoimmune disorders can impair healing.

27. Factors Affecting Wound Healing
• Other
▫ Immune System Function
▫ Medications
▫ Smoking
▫ Obesity
▫ Wound Type and Location
▫ Stress

28. Complications
• Infection: Can lead to
increased pain, swelling,
redness, and discharge.

29. Complications
• Excessive Scar Formation:
Keloids or hypertrophic scars
may develop.

30. Complications
• Dehiscence: Wound
edges separate before
healing is complete.

31. Complications
• Hemorrhage: Excessive
bleeding from the wound.
