There are several types of wounds including incisions, contusions, abrasions, punctures, and lacerations. Wound drainage can include serous, purulent, or sanguineous exudate. The RYB color code categorizes wounds as red, yellow, or black based on their appearance and healing phase. Red wounds are usually healing and require protection. Yellow wounds contain slough or pus and should be cleansed. Black wounds have necrotic tissue that requires debridement. Wound cleaning involves using isotonic saline to clean or irrigate wounds as needed based on the amount of exudate or foreign material present.

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. 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.

16. 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.

17. YELLOW WOUNDS - Characterized by primarily by liquid to semiliquid “slough” that is often accompanied by purulent discharges.

19. CLEANSETHE YELLOWWOUNDS Yellow wounds should be Cleanse to absorb drainage and remove nonviable tissue. Apply wet to wet dressing. Hydrogel dressings Exudate absorbent dressings

20. BLACK WOUNDS This type of wound is covered with necrotic tissue. BLACK WOUNDS requires debridement ( removal of infected and necrotic material)

25. To protect the wound from microbial contamination

27. To absorb drainage or debride the wound

28. To prevent haemorrhage

29. To splint or immobilize the wound site and prevent further injury
