Prevention Because Pain Mortality Financial Burden
Pressure Ulcer Incidence Viewed as an indicator of poor quality care Pressure ulcers 2 nd most common claim for wrongful death
2007 Pressure Ulcer Definition A pressure ulcer is localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in combination with shear and/or friction.
Normal Capillary Blood Flow Pressure is 32 mm Hg. When greater than 32mm Hg pressure is applied, the capillary blood flow is impeded and tissue damage results.
Sites of Pressure Ulcers 65-75% in pelvic area 20-25% on feet
Critical Determinants for Pressure Ulcer Development Pressure Shear/Friction Tissue Tolerance to Pressure & Shear
Intensity & Duration of Pressure High-intensity pressures for a short period of time can result in tissue damage With low-intensity pressures, it takes a longer period of time to cause tissue damage
Factors that Effect Tissue Tolerance to Pressure Nutritional Debilitation Fecal Incontinence Advanced Age Chronic Illness Low Blood Pressure Elevated Body Temperature Smoking
Risk Factors History of Pressure Ulcers Unable or fails to do weight shifts indep. Fecal Incontinence Significant weight loss or gain due to edema Albumin of 2.5 or lower Leaves 25% of tray uneaten
Risk Factors (cont.) Diabetes, chronic disease Vascular disease Physical Impairments muscle contractures arthritis
OR Risk Factors Age Comorbity (diabetic, pulmonary, cardiac) Time on table > 2 hours Position Type of surgery Hypotensive episodes Decrease H&H
OR Risk Factors (cont) Anesthetic Agents - disrupt normal vasodilatation and constriction Pooling of prep solutions - changes ph of skin Straps Length of time in OR Friction Shear
OR Risk Factors (cont.) Elevated limbs - reduced perfusion Warming blankets increases metabolic rate = requires greater cellular need for oxygen, nutrients, increased rate of by product removal may not be achievable with anesthesia, immobility, vascular compromise
Environmental Risk Factors OR table pads Standard plus gel overlay Viscoelastic foam (memory foam) When comparing against each other patients were 8x more likely to develop a PU on standard plus gel overlay (Scott, Williams, Lummas 2005)
The Patient at Risk All OR patients at some level of risk Surgical patients = 42% of all Hosp Acquired Pressure Ulcers Any ulcer that develops within 5 days of an OR visit is considered acquired in the OR Pressure related deep tissue injury under intact skin
Determining Risk Braden daily in acute care OR?? Scott triggers Age over 62 Albumen <3.5 ASA score 3 or greater OR over 2 hours
Staging of Pressure Ulcers Updated staging 2007, from National Pressure Ulcer Advisory Panel
Suspected Deep Tissue Injury Purple or maroon localized area of discolored intact skin or blood-filled blister due to damage of underlying soft tissue from pressure and/or shear. May be painful, firm, mushy, boggy, and warmer or cooler that surrounding tissue. Evolution may be rapid even with treatment.

Staging
Stage II Pressure Ulcer
Stage II Pressure/Shear Ulcer
Stage II Heel Blisters
Stage III Pressure Ulcer
Stage III Full Thickness
Stage IV Pressure Ulcer
Stage IV
Unstagable Full thickness tissue loss in which the base of the ulcer is covered by slough (yellow, tan, gray, green, or brown,) and/or eschar (tan, brown, or black) in the wound bed. Until enough slough and/or eschar is removed to determine true depth, the ulcer cannot be staged.

Relieve Pressure Standard is every 2 hours?? During procedure?? Heels / Gel pads?? Boots
Perform complete skin assessment When positioning on table Before transfer to PAR Document all issues
Friction In OR Transfer to table Position changes Heel sliding during transfer pre-op, intra-op, post-op Tape applied with tension epidermal stripping chemical injury - trapping irritating chemicals Drape removal
Shear Shear is caused by the force of gravity pushing down on the body and the resistance between the patient and a surface such as the bed or chair.
Shearing Forces Shear causes much of the damage seen with pressure ulcers
Shear Forces In OR Reverse Trendelenberg / high lithotomy/ Side shifting Other unusual positions Repositioning during procedure Tape applied with tension
Operating Room Interventions: Prevention Identify the Patient at Risk Relieve Pressure use least amount of linen under patient as possible Prevent Shear / Friction Use Pressure Redistribution Surfaces
Interventions (cont.) Skin Prep under tape Apply tape opposite to incision Apply tape without tension
