15
Q
  • Occurs within minutes after initial wound
  • Starts with vasoconstriction then vasodilation
  • Wound is rinsed and filled with blood-collagen and fibrin constituents
  • Cytokines are produced in this stage
  • Scab formation (platelets)
  • Active bleeding of the wound
  • Clot formation
  • Scab formation
A

16
Q

occurs 3-5 days after initial injury
- Epithelium regulates collagen fiber
- Migration of collagen, fibroblasts and the like

  • Fibrin network : scaffold for wound, support for collagen, attracts more platelets
  • “ Itchy phase“
  • Re-epithelialization
  • Resorption of blood collagen
  • Angiogenesis occurs
  • Epithelial proliferation and migration
  • Longest phase
  • Wound contraction : wound is smaller due to re-epthilialization, centripetal movement of epithelial cells
A

PROLIFERATION phase

17
Q
  • Growth of new epithelial cells
  • Reorganization of collagen to provide a sturdier support
  • 14-21 days of remodeling
  • Tissue layers are not as strong as original tissue

A

Wound management

21
Q
  • Stabilize the patient
  • Physical examination
  • Wash, clip and shave
  • Removal of gross debris
A

Initial management

22
Q
  • Removal of foreign material, necrotic, damaged or if infected tissues such as wound edges
A

Debridement

23
Q

For cases of _______, wound edges should be as clean as possible so healing and apposition could occur as clean as possible

A

laceration

24
Q

(3) types of Debridement

[ SEM ]

A
  1. Surgical
  2. Enzymatic
  3. Mechanical
25
Q

debridement that uses sharp scissors or scalpel

require anesthesia

A

Surgical

26
Q

Debridement that selectively removes non viable
tissues, fine debridement,

Indicated in patients with
increases anesthesia patients (trypsin and chymotrypsin)

A

Enzymatic

27
Q

uses adherent bandages, contaminated tissue remains even after surgery

A

Mechanical

28
Q

Following _____ and _____, decide whether to close wounds by sutures or not

A

excision and debridement

29
Q

(3) Categories of Wound Healing

A
  1. First intention / Primary wound closure
  2. Second intention / Secondary wound closure
  3. Third intention / Tertiary wound closure
30
Q

Stitch wound that is already debrided (minor wound or
surgery)

Use of surgical stapler non absorbable or absorbable suture materials

A

First intention / Primary wound closure

31
Q

Performed mainly for wounds located at limbs (avulsion);

Used for skin with much tension

Simple bandaging but no surgical procedures or suturing

Intervention of wound by medical approach

Longer time for wound to heal

A

Second intention / Secondary wound closure

32
Q

re-epithelialization first before wound closure

A

Third intention / Tertiary wound closure

33
Q
  • It is important to know the size and type of suture
    material
A

Suturing

34
Q

What kind of suture should be used in SKIN?

A

Non-absorbable sutures

35
Q

What kind of suture should be used in INTERNAL ORGANS

A

Absorbable sutures

36
Q

Suture:

The higher the number = the ____ the diameter

A

smaller

37
Q

infection could be more common in this type of suture

A

Monofilament / Multifilament

38
Q
  • Reduce or eliminate the dead space;
  • Protects wound from external trauma and bacteria
  • Absorbs secretion such as EXUDATE (allow characterize the lesion); should press against dead space;
  • Decreases edema and hemorrhage ; immobilizes wound and promote healing;
  • Vehicle for antibiotics and antiseptics ; should be applied not too loosely or tight
A

Bandaging

39
Q

exit point for blood, pus or serum accumulation

A

Drainage

40
Q

uses gravity or capillary action

A

Passive drainage

41
Q

____ rubber causes additional inflammation

A

Latex

42
Q

vacuum, uses NEGATIVE pressure

A

Active drainage

43
Q
  • Container switch vacuum
  • Drainage is faster
  • Extra apparatus is required which results to discomfort
A

Active drainage
