PT goals for wound care
promote healing, control pain and edema, protect the wound from trauma
True or False? The role of the PTA during wound care includes prevention of
pressure ulcers.
True, the role of the PTA during wound care includes prevention of pressure
ulcers
epidermis
outermost layer; formed by keratinocytes; contains melanocytes (color);
regenerative every 4-6 weeks; protects against water loss and physical damange;
sensation
dermis
composed of collagen and elastin fibers and extracellular matrix; contains blood
and lymphatic vessels, never endings, hair follicles, sebaceous and sweat
glands, fibroblasts
subcutaneous/hypodermis
composed of adipose and connective tissue; contains major blood and lymph
vessels and nerves
functions of the skin
protection, sensory perception, thermoregulation, excretion, metabolism,
absorption, social communication
phase 1 healing
, inflammation; days 1-5; edema and necrosis; normal immune
response; initial vasoconstriction; vasodilation, increased blood flow facilitates
healing
what makes it difficult for blood and oxygen to reach the wound tissue?
edema and necrosis
causes of abnormal inflammatory response
Immunosuppressive medications; arterial Insufficiency; medical conditions that
alter the immune response
phase 2 healing
proliferation; days 3-20; fibroblasts secrete collagen (type III); angiogenesis,
granulation, epithelialization
what is needed to promote formation of new tissue?
oxygen
phase 3 healing
remodeling/maturation; day 9-2 years; type III collagen converts to type I;
decreased capillaries; scar tissue contracts and matures
regeneration
replacement of destroyed tissue by the same kind of cells
fibrosis
repair by dense fibrous connective tissue (scar tissue)
acute wound
new; occurs suddenly; healing progresses in timely, predictable manner;
typically heals by primary intention
chronic wound
may develop over time; healing has slowed or stopped; typically heals by
secondary intention
factors that affect healing
