Q

Partial-Thickness Wounds:

A
  • Damage to epidermis, upper layers of dermis

Q

Full-Thickness Wounds:

A
  • Damage extends into lower layers of dermis, underlying subcutaneous tissue
  • Must be filled with granulation tissue to heal

Q

Process of Wound Healing (3):

A
  1. First intention – Edges brought together with skin lined up in approximated position
  2. Second intention –Granulation and contraction; deeper tissue injury or wound
  3. Third intention –Delayed closure; high risk for infection with resulting scar

29
Q
  1. Hemostasis:
A

injured blood vessels constrict, and platelets gather to stop bleeding, clots form a fibrin matrix that provides framework for cellular repair

30
Q
  1. Inflammatory Phase:
A

damaged tissue and mast cells secrete histamine, resulting in vasodilation of surrounding capillaries and exudation of serum and white blood cells into damaged tissues

31
Q
  1. Proliferative Phase:
A

begins and lasts from 3-24 days

filling the wound with granulation tissue, contraction of the wound, and resurfacing by epithelialization

32
Q
  1. Remodeling:
A

Takes sometimes more than a year

The collagen scar continues to reorganize and gain strength over several months

33
Q

Wound Assessment:

A
Location
Size
Color
Extent of tissue involvement
Cell types in wound base and margins
Exudate
Condition of surrounding tissue
Presence of foreign bodies
34
Q

Wound Management: Nonsurgical:

A
Dressings
Physical/drug/nutrition therapies
Electrical stimulation
VAC
HBOT
Topical growth factors
