Skin Facts • Largest body organ • pH 4.2 – 5.6 • Normal flora • Texture
Function of Skin • Protection • Thermoregulation • Sensation
Advanced age Cognitive impairment/altered sensory perception Diabetes Inadequate perfusion/ oxygenation/circulation Impaired immunity Incontinence/moisture Infection Medications Malnutrition Obesity Preoperative illnesses/co-morbidities Underweight Risk Factors for Impaired Healing
Wound Healing • Anti-inflammatory agents • Lathyrogens • Age • Nutrition • Wound coverage • Chemotherapy
Wound Healing • Infection • Surgical technique • Environmental temperature • Denervation • Radiation therapy • Diabetes mellitus
Five Major Components in the Healing Process • Inflammation • Cellular proliferation • Connective tissue formation • Wound contraction • Wound remodeling
Components Inter-Related • Dependent on: • Adequate energy for cell proliferation, cell movement, and protein synthesis • Adequate protein, amino acids, and peptides for protein synthesis • Adequate micronutrients for metabolic activity • Adequate anabolic stimuli, in the form of growth factors and anabolic hormones
Wound Assessment • Location, size • Color, odor, texture • Exudate • Undermining
Wound Assessment • Eschar • Granulation • Wound margins • Time in existence / treatment
Venous Ulcers Characteristics • Medial lower leg and ankle • Hyperpigmentation • Superficial • Exudate
Venous Ulcers Goal • Increase venous return • Decrease venous stasis / edema • Wound environment • Appropriate compression • Treat perforators
Arterial Ulcers Characteristics • Anywhere on leg/foot/toes • Painful • Dry eschar • Punched out • Skin shiny/light • No pulses
Arterial Ulcers Goal • Improve vascularity • Protect • Moisten • Debride gently
Yeasts and Fistulas • Are an entirely different look
