2. Definition A wound is a break in the integrity of the skin.

3. Phases of Wound Healing Inflammatory (immediate) Fibroblastic (day 4-20) Maturation (6-12 months)

4. Factors Which Impact Wound Healing Tissue perfusion and oxygenation Nutritional status Presence or absence of infection Diabetes Mellitus Corticosteroid administration Immunosuppression Age Stress Other systemic factors Topical therapy Waldrop & Doughty, Acute and Chronic Wounds, 2000

5. Patient Assessment Medical/Surgical History Medications (include OTC) Nutritional Assessment Pain Psychosocial Assessment Cultural/ethical considerations

6. Wound Assessment Location Stage/Classification Size (LxWxD in cms) Sinus Tract(s) Undermining Exudate Necrotic Tissue Granulation Tissue Signs/Symptoms of Infection Periwound Skin

7. Acute Wounds Classification  Partial Thickness (involve epidermis/dermis only)  Full Thickness (involve subcutaneous tissue and possibly underlying structures) Usually heal following normal wound healing pathways

10. Chronic Wounds Pressure Ulcers Venous Stasis Ulcers Arterial Ulcers Neuropathic Ulcers Usually have impaired healing mechanisms

11. Pressure Ulcers

12. Venous Stasis Ulcer

13. Arterial Ulcer

14. Neuropathic Ulcer

15. Topical Therapy: Principles Remove necrotic tissue and foreign bodies or particles Identify and eliminate infection Obliterate dead space Absorb excess exudate Maintain a moist wound surface Provide thermal insulation Protect the healing wound from trauma and bacterial invasion Doughty, Acute and Chronic Wounds, 1992
