Document Summary
Connects dermis to underlying muscle and bones. Affect skin integrity (free of abrasions, cuts, lesions, etc. ) Medications doxycycline, coumadin/blood thinners, steroids, nsaids. Wound depth (superficial, partial thickness, full thickness) Chronic (takes longer to heal) v. acute. Healing process (inflammatory 3-5 days, proliferative, maturation: skin is never the same, always weaker. Heat, electricity, chemicals, radiation, extreme cold, friction. Oxygenation, tissue perfusion: need blood flow. Infection: cure the infection before the wound itself. Dehiscence (skin layers start to separate) and evisceration (everything through the skin: risk factors, easily infected, diabetics, obese, post-op has increased vomiting, respiratory issues. Fistula formation: ope(cid:374)i(cid:374)g to the ski(cid:374) or a(cid:374)other orga(cid:374) that should(cid:374)"t be there, chronic cancer patients, chro(cid:373)e"s disease. Start to form 15 minutes compromised patient. A localized injury over usually a bony prominence caused by pressure or by a combination of pressure and shearing. Braden scale for predicting pressure sore risk.
