Wounds And Burns Flashcards
Epidermis cell types
Melanocytes
Langerhans - infection
Merkel cell - light touch
Keratinocytes - epithelialization
Dermis contains…
Blood vessels
Lympathics
Nerve endings
Glands, nails, hair
Subcutaneous tissue
Loose CT< adipose tissue, elastin
Infection
Excess edema
Hot to touch, fever, malaise
Large exudate
Red, may be blistering
Severe pain no position of comfort
Inflammatory phase main points
Debris removal, cell repair and regeneration
Platelets aggregate at injury site, release of WBCs
Edema, redness, inflammation, pain
Proliferative phase
Angiogenesis and epitheliallization
Granulation tissue fills in wound
Fibroblasts pull wound edges in
Remodeling
New collagen forms, old collagen breaks down
Epibole
Sign of halted process
Manage via cross-hatching, silver nitrates to burn edges
Arterial wounds
Ischemia
Dry wound bed
Even edges
PAD
Bergers test
Venous wounds
Valves faulty or obstruction or lack of pumping, cannot get blood out of area
Majority of wounds
Wet wound bed, gaiter area, hemo staining
Neuropathic
Linked with DM — hyperglycemia increases stiffness of vessels
Stage 2 pressure injury
Only one thats partial thickness loss
Non-selective debridement (4)
Wet to dry (waxing)
Irrigation
Hydrotherapy (whirlpool)
Abrasion
Selective debridement contraindications
Stable heel eschar
ABI <0.8
Coagulation therapy
Gangrene, osteomyelitis
**unidentified structures
**terminally ill
Selective types of debridement
Autolytic
Enzymatic
Biosurgical
Sharp debridement (requires MD orders)
Surgical (MD only)
