It is a wound with tearing of tissues with irregular wounds edges, Often from accidents.
![Page 9: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/9.jpg)
PENETRATING WOUND• Penetration of the skin and the underlying
tissues. It is caused by a foreign object or instrument entering deep into body tissue

KINDS OF WOUNDS DRAINAGE
Exudate - is material, such as fluid and cells, that has escaped from blood vessel during the inflammatory process.
![Page 17: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/17.jpg)
1. Serous exudate - consist chiefly of serum or the
clear.2. Purulent Exudate - It is thicker, yellow, green
consist of WBC exudates due to presence of pus.
![Page 18: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/18.jpg)
3. Sanguineous exudate - Consist of large amounts of
red blood cells, indicating damage to capillaries that is severe enough to allow the escape of red blood cells.
![Page 19: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/19.jpg)
4. Sero-sanguineous exudate - mixture of serous and
sanguineous pale-red watery.
![Page 20: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/20.jpg)
THE RYB COLOR CODE
This concept is based on the color of an open wound - Red, Yellow, Black.
![Page 21: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/21.jpg)
• Red wound - are usually in the late restoration phase of tissue repair and are clean and pink in appearance
this type of wound needs to be protected.
![Page 22: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/22.jpg)
![Page 23: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/23.jpg)
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.
![Page 24: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/24.jpg)
YELLOW WOUNDS
• - Characterized by primarily by liquid to semiliquid that is often accompanied by purulent discharges.
![Page 26: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/26.jpg)
CLEANSE THE YELLOW WOUNDS
Yellow wounds should be Cleanse to absorb drainage and remove nonviable tissue.
1. Apply wet to wet dressing.2. Hydrogel dressings3. Exudate absorbent dressings
![Page 27: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/27.jpg)
BLACK WOUNDS
This type of wound is covered with necrotic tissue.
BLACK WOUNDS requires debridement
( removal of infected and necrotic material)
![Page 29: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/29.jpg)
GUIDELINES IN WOUND CLEANING
Use Isotonic saline to clean or irrigate the wound.
Warm the solution to body temperature before use.
![Page 30: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/30.jpg)
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.
![Page 31: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/31.jpg)
Use gauze squares. Avoid using cotton balls and other products that shed fibers into the wound surface. The fibers become embedded in the granulation tissue and act as a source for infection
![Page 32: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/32.jpg)
Consider cleaning superficial noninfected wounds by irrigating them rather than by mechanical means.
![Page 33: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/33.jpg)
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
![Page 34: WOUND DRESSING. Wound It is a break in the continuity of the skin, mucous membranes, bone, or any body organ.](https://reader035.fdocuments.in/reader035/viewer/2022081503/5697bfe71a28abf838cb5c9d/html5/thumbnails/34.jpg)
To absorb drainage or debride the wound
To prevent haemorrhageTo splint or immobilize the
wound site and prevent further injury
