Question | Answer |
skin integrity | overall status of skin. |
factors that affect skin integrity for babies | thin, fragile, diaper rash, lose heat quickly |
factors that affect skin integrity for elders | drier, reduced healing, loss of fat, changes in collagen, decreased elasticity |
factors that affect skin integrity for people with mobility issues | increases pressure on skin which decreases 02 to tissues |
factors that affect skin integrity for people with impaired nutrition/hydration | poor turgor (elasticity) |
factors that affect skin integrity for people with diminished sensation | lead to injury due to not feeling the pain or treating the wound. |
factors that affect skin integrity for people on medications | itches, rashes |
factors that affect skin integrity for people with poor circulation | effects tissue metabolism; arterial and venous |
wound | disruption in the normal integrity of the skin and the underlying tissues |
wounds are assessed for... | appearance, size, drainage, pain, sutures, drains, tubes, complications. |
Classification of the wound is done by noting if it is 1______, 2_______, 3________. | 1. open or closed
2. acute or chronic
3.clean, contaminated, infected
4. superficial or full thickness
5. is it penetrating |
Pressure Ulcer - Stage I | persistent red, blue or purple. No open wounds, blanching |
Pressure Ulcer - Stage II | partial thickness skin loss, presents as abrasion or blister |
Pressure Ulcer - Stage III | full thickness, crater |
Pressure Ulcer - Stage IV | full thickness, crater, exposed bone, tendon or muscle |
3 phases of wound healing | Inflammation
Proliferative
Maturation |
Inflammation Phase | Hemostasis and inflammation occur here. Fluids rush to site (edema) to contain infection. Clotting starts here as well. |
Proliferation Phase | Fibroblasts enter the wound, collagen synthesis occurs, new blood and lymph vessels form and epithelial proliferation and migration continue. |
Maturation Phase | Collagen fibers are remodeled, tensile strength increases, the wound begins to contract and the wound is "healed" |
Three methods of wound healing | Primary
Secondary
Tertiary |
Primary Intention | tissue properly closed with little tissue reaction, granulation tissue is not visible and scarring is minimal |
Secondary Intention | From infected wounds or in wounds whose edges have not been properly approximated. Tissue loss is experienced, wound heals from inside out. Usually packed with saline moistened dressings, covered in dry cloth. |
Tertiary Intention | Deep wounds that have not been sutured early or who have needed resuturing. Deep, wide scar results. |
Serous exudates | straw colored drainage |
sanguineous | bloody drainage |
serosanguineous | mix of bloody and straw colored |
purulent | yellow, contains pus |
Major complications of wound healing | Hemorrhage-concealed bleeding beneath skin
Infection - wound sepsis
Dehiscence - separation of wound edges
Evisceration - protrusion of wound contents
Fistula formation - abnormal passageway |
Factors involved in pressure ulcers | Immobility
Impaired sensory perception
Decreased tissue perfusion
Decreased nutritional status
Friction/Shear
Increased moisture
Age-related skin changes |
