Acute Wounds

ClassificationPartial Thickness (involve epidermis/dermis

only)Full Thickness (involve subcutaneous tissue

and possibly underlying structures) Usually heal following normal wound

healing pathways

Chronic Wounds

Pressure Ulcers Venous Stasis Ulcers Arterial Ulcers Neuropathic Ulcers Usually have impaired healing

mechanisms

Pressure Ulcers

Venous Stasis Ulcer

Arterial Ulcer

Neuropathic Ulcer

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
