 Wound It is a break in the continuity of the
skin, mucous membranes, bone, or any body
organ

 TYPES OF WOUNDS
 INCISION
 It is cause by sharp instrument. Ex knife or
scalpel.
 CONTUSION
 Cause by blowFrom a blunt Object.
 Closed woundSkin appears ecchymotic
 ABRASION
 Surface scrape, either Unintentional or
Intentional It is an open wound Involving the
skin, Painful

 PUNCTURE
 Penetration of the Skin and often, the
Underlying tissues From a sharp Instrument.
 LACERATION
 Tissues torn apart Often from accidents
 PENETRATING WOUND
 Penetration of the Skin and the Underlying
tissues. (eg.gun short )

 THE RYB COLOR CODE
 This concept is based on the color of an open
wound - Red, Yellow, Black
 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
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.

 YELLOW WOUNDS
 Characterized by primarily by liquid to
semiliquid “slough” that is often accompanied
by purulent discharges.
 CLEANSETHE YELLOWWOUNDS
 Yellow wounds should be Cleanse to absorb
drainage and remove nonviable tissue.
 Apply wet to wet dressing.
 Hydrogel dressings
 Exudate absorbent dressings

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

 Red wound
 Black wound
 Yellow wound

 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.
 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
 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
 Consider cleaning superficial noninfected wounds
by irrigating them rather than by mechanical
means
 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
 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
