  • 1. WOUND DRESSING
  • 2. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ
  • 3. TYPES OF WOUNDS
  • 4. INCISION It is cause by sharp instrument. Ex knife or scalpel.
  • 5. CONTUSION Cause by blow From a blunt Object. Closed wound Skin appears ecchymotic
  • 6. ABRASION Surface scrape, either Unintentional or Intentional. It is an open wound Involving the skin, Painful.
  • 7. PUNCTURE Penetration of the Skin and often, the Underlying tissues From a sharp Instrument.
  • 8. LACERATION Tissues torn apart, Often from accidents.
  • 9. PENETRATING WOUND • Penetration of the Skin and the Underlying tissues.
  • 10. KINDS OF WOUNDS DRAINAGE Exudate - is material, such as fluid and cells, that has escaped from blood vessel during the inflammatory process and is deposited in tissue or on tissue surfaces.
  • 11. 1. Serous exudate - consist chiefly of serum or the clear portion of the blood derived from the blood and serious membranes. 2. Purulent Exudate - It is thicker than serous exudate due to presence of pus.
  • 12. • 3. Sanguineous exudate - Consist of large amounts of red blood cells, indicating damage to capillaries that is severe enough to allow the escape or red blood cells.
  • 13. THE RYB COLOR CODE This concept is based on the color of an open wound Red, Yellow, Black.
  • 14. • Red wound - are usually in the late regeneration phase of tissue repair and are clean and uniformly pink in appearance this type of wound needs to be protected.
  • 15. Protect the Red wound a. gentle cleansing b. avoiding the use of dry gauze or wet to dry saline dressings. c. applying a topical antimicrobial agent. d. changing the dressing as infrequent as possible.
  • 16. YELLOW WOUNDS •- Characterized by primarily by liquid to semiliquid “slough” that is often accompanied by purulent discharges.
  • 17. CLEANSE THE YELLOW WOUNDS Yellow wounds should be Cleanse to absorb drainage and remove nonviable tissue. 1. Apply wet to wet dressing. 2. Hydrogel dressings 3. Exudate absorbent dressings
  • 18. BLACK WOUNDS This type of wound is covered with necrotic tissue. BLACK WOUNDS requires debridement ( removal of infected and necrotic material)
  • 19. GUIDELINES IN WOUND CLEANING  Use Isotonic saline or lactated ringers solution to clean or irrigate the wound. Warm the solution to body temperature before use.
  • 20. If wound is grossly contaminated by foreign material, bacteria, or necrotic tissue, clean the wound at every dressing change. If wound is clean, has little exudate, and reveals healthy tissue avoid repeated cleaning.
  • 21.  Use gauze squares. Avoid using cotton balls and other products that shed fibers onto the wound surface. The fibers become embedded in the granulation tissue and act as a foci for infection
  • 22. Consider cleaning superficial noninfected wounds by irrigating them rather than by mechanical means.
  • 23. Purpose of wound Dressings To protect the wound from mechanical injury To protect the wound from microbial contamination To provide or maintain high humidity of the wound
  • 24. To provide thermal insulation To absorb drainage or debride the wound To prevent haemorrhage To splint or immobilize the wound site and prevent further injury
