Identify Common Wound Types

• Diabetic foot ulcers

• Pressure ulcers

• Venous ulcers

• Arterial ulcers

• Burns

• Non-healing surgical wound

• Odds and ends

Diabetic foot wounds

• Individual lifetime risk of 15-25% of developing an ulceration.

• Most common cause of non-traumatic amputations.

• Over 60% of patients with a healed ulcer will have a recurrence within 5 years.

• After amputation, up to half of these patients will have a higher level or contralateral amputation within 5 years.

• 47% increase in 5 year mortality in patients with DFU over those without.

Pathophysiology of diabetic foot ulcers

• Progressive sensory, motor and autonomic neuropathy• Loss of protective sensation

• Progressive deformity with altered and increased plantar pressures

• Changes in dermal blood flow regulation

• Arterial occlusive disease

• Cellular dysfunction – impaired healing due to decreased NO synthesis

Basic Diabetic Ulcer Management• Debridement

• Infection control• Topical

• Systemic

• Moisture balance

• Off-loading

• Perfusion

Page 15: Introduction to Wound Care - nhafp.orgnhafp.org/pdf/intro-to-wound-care.pdf · Introduction to Wound Care Duane Dietz, MD Concord Hospital Wound Healing Center

Pressure ulcers

• Ulcers in the regions of skin overlying bony prominences in debilitated or otherwise immobilized patients.

• Associated with comorbidities• Deformities

• Undissipated forces including pressure, shear or tension over bony prominences

• Ischemia – both long and short term

• Malnutrition

• Moisture retention and incontinence.

Page 16: Introduction to Wound Care - nhafp.orgnhafp.org/pdf/intro-to-wound-care.pdf · Introduction to Wound Care Duane Dietz, MD Concord Hospital Wound Healing Center

National Pressure Ulcer Advisory Panel (NPUAP)Staging System for Pressure Ulceration

• Staging system used by Agency for Health Care Research and Quality (AHRQ)

• Staging system used for ICD-9 and ICD-10 coding.

• Four ulcer stages and two additional pressure injury categories.
