wound healing

what is it

the body’s process of repairing and regenerating tissue after injury

• involves inflammatory, proliferative, and maturation phases

• proper healing is essential for optimal recovery and minimizing complications

phase

• hemostasis

• inflammation

• proliferation

• maturation

factors affecting wound healing

• age

• obesity: decrease oxygen to wound

• nutrition

• oxygenation and circulation: need proper blood flow

• diabetes

• corticosteroids

• immunosuppressive agents

complications of wound healing

• keloid - raised thick scar

• contractures - tightening of wound tissue

• dehiscence - premature separation of wound edges

• evisceration - wound opening with protrusion of internal organs

• stricture - abnormal narrowing of body passage

• fistula - abnormal connection between organs or skin

• adhesions - internal scar tissue between tissues or organs

pharmacology in wound healing

• topical antibiotics - prevent infection but can cause allergic reactions

• growth factors - stimulate cell proliferation, but can cause infection and tissue irritation

• corticosteroids - reduce inflammation but inhibit healing and collagen formation, but can delay healing and increase infection

nursing condiserations for wound

• wound assessment

• infection prevention

• nutritional support

• pain management

• patient education
