Integrating Palliative and Curative Wound Care
Prevalence of Wounds Integrating Palliative and NPUAP (2001) Hospice population 14% – 28 % Curative Wound Care LTC and Rehab 2% – 28% SCI Units 10% – 30 %
Rosene D. Pirrello, Pharmacist Specialist Palliative Care Team Tippett (2005) – 35% of 400 patients in a single hospice had a skin wound
Reifsnyder and Magee (2004) – 26.9% of 980 patients at 4 hospices had pressure ulcers
Outline What Types of Wounds?
• Prevalence and type • Prevention • Assessment, preparation, dressing • Managing pain, odor, exudate, bleeding
Types of Wounds How Many Wounds? • Pressure – 50 % • Malignant – 30 % • Venous / edematous – 10 % • Arterial – 5 % • Surgical – 5% • Diabetic – few • Skin Tears – ?

Co-morbid Disease
• Dementia • Stroke • Peripheral Vascular Disease Prevention . . . • Diabetes • Cancer
Pathophysiology… Risk Assessment What is the root cause of all wounds ? Braden Pressure Ulcer Risk Assessment • Pressure • Tissue necrosis in 1 2 3 4 • Malignant Dermis Sensory perception Moisture • Venous / edematous Fat Muscle Activity • Arterial Mobility Associated structures • Diabetic Nutrition Nerves Friction / shear Tendons Vessels Bergstrom N, Braden BJ – Nurs Res 1987
Pressure Relief: …Pathophysiology Surfaces / Positioning • Wounds & surrounding tissues susceptible to Beds Infections Group 1 – Pressure relief mattress Inflammation Group 2 – Low air loss Group 3 – Air fluidized

Group 1
Well-fitting, smooth sheets
Reduce Pressure, Shear, Friction and Group 2 Moisture • High pressure – short • Positioning q 2 hours period only • Weight shift q 15-30 min • Head board < 30° X 5 seconds • Footboard or elevate • Side position at 30°angle knees • Pillow under calves • Protect elbows/heels when on back • Powder of bedpans • Assure adequate device inflation • Incontinence plan, standards

Assess • Person Symptoms Assessment . . . “Woundedness” • Wound Type, cause Bacterial burden • Context Underlying illness(es), prognosis Nutritional status
Margaret . . . • 68 year old woman • Metastatic lung Ca • Spinal cord compression, paraplegia • Cared for at home • Nutrition good • Loving family
Woundedness Assess the Wound
• Patient • Dysfunction • Size: L – W – D • Exudate Serous • Family • Dependence • Tunneling Serosanguineous • Caregivers • Anxiety • Undermining Purulent • Depression • Color • Odor • Fear Red = viable tissue Putrid • Abandonment Yellow = slough Fruity • Spiritual Black = eschar • Bubbling

How to Measure and Chart . . . Pressure Ulcer Staging
• Stage III – full thickness skin loss damage or necrosis of subcutaneous tissue not through underlying fascia • Stage IV – full thickness skin loss extensive damage or necrosis of muscles, bone or supporting structures Undermining Sinus tracts
. . . Margaret
• Stage III, sacral ulcer 5 cm X 8.5 cm, undermining, Feet Head additional 10 cm tunneling Color: Red, yellow, bluish-green Fruity smell • Stage II, dermal breakdown • Goal: Healing
Pressure Ulcer Staging . . . Management Strategies
• Stage I – persistent changes in a Healable Non-healable defined area of intact skin related to pressure Red, blue or purple hues • Stage II – partial thickness skin loss Epidermis and / or dermis

Goal of Wound Care . . . Margaret
“The goal is to decrease the burden of the • Stage X, R heel ulcer wound, while simultaneously hoping that eschar the interventions will promote healing.” 4 x 6 cm • Stage III, sacral ulcer “Hoping for the best, planning for the worst” 5 x 8 cm; • Goal: Healing

Wound Pain Debridement Nociceptive pain –due to chemical, • Surgery fastest, eg, scalpel, curette, scissors mechanical & thermal stimuli Aggressive – Wound edges Non-aggressive – Surrounding tissues • Autolytic (dressings) – Muscle sheaths • Enzymes – Periosteum Collagenase • Mechanical, e.g., hydrotherapy • Maggot therapy
Wound Pain
Neuropathic pain – due to nerve damage, death Debridement . . . Hyperalgesia – due to inflammation – Sensitizes & recruits REQUIRES ADVANCE PLANNING FOR PAIN – Nociceptors – Opioid receptors Allodynia
Temporal Profile Plan for Pain Wound Pain Experience • Pre-medicate with analgesics / Adapted from Diane Krasner, 2010 anaesthetics • Choose analgesics to match pain temporal 1. Acute Intermittent profile to analgesic first order Cyclic -dressing changes pharmacokinetics -turning, repositioning 2. Acute Intermittent Match duration of
Noncyclic procedure to t½ -sharp debridement -drain removal Wait tCmax before 3. Constant starting -inflammation -underlying disease procedure
