Prediction and Prevention of Pressure Ulcers
Treating and nursing pressure ulcer
Economic consequences of pressure ulcers
Frequency: 3-14%,2-25%(nursing home) 85.7% paraplegia 58% pressure ulcer > 65y
Economic consequences: Days in hospital increase Cost of heath care increase: $4,000-40,000
decubitus ulcer, and bedsore
Concept: pressure sore,
a localized area of tissue lesion and necrosis that tends to develop when soft tissue is compressed between a bony prominence and an external surface for a prolonged period, blood circulation is obstructed, and local tissue is ischemic.

Age
Gerontologic nursing practices for the client with impaired skin integrity
★Older adult’s skin is less tolerant to pressure, friction, and shearing force because of decreased elasticity due to normal aging.
★The older adult has decreased number of sweat glands, leaving the skin dry and less tolerant to shear and friction.
★Impaired skin integrity is a high risk to older adult; it is among the five most common nursing diagnoses for older adult clients in long-term care facilities.
★Dermis of the older adult’s skin is thinner due to the normal absence of subcutaneous fat, therefore making the older adult more susceptible to skin breakdown.
★After the age of 50 epidermal cell renewal reduces by one third, and as a result wound healing is approximately 50% slower than a 35-year-old adult.
★In the presence of chronic coronary or peripheral vascular diseases circulation to the extremities is reduced.
Fever (infection)
increase the body’s metabolic rate increasing the needs of the cells for oxygen Make hypoxemic tissue more susceptible to
ischemic injury diaphoresis

1965 年 Indan等通过研究报告了人在坐和卧位时压迫点的分布,仰卧时,枕骨粗隆、骶尾部、足跟是压迫最重的部位,压力范围 5.3~ 8.0kPa(40 ~
60mmHg) 。
俯卧时膝部和胸部受到的压力接近 6.7kPa(50mmHg)
坐位时 ,集中到坐骨结节的压力高达10kPa(75mmHg) 。

Preventative interventions
Preventative interventions
Avoid pressure on local tissues for prolonged period
Reduce shear and friction Protect skin of patients (Hygiene and
skin care) Stimulating blood circulation of skin Provide adequate nutrition Health education
Avoid pressure on local tissues for prolonged period
Turn the patients periodically (every 2 hours or 30 minutes necessarily)
Protect bony prominence and support interspace
Use the devices right, such as plaster, bandage, splint, retractor
Avoid pressure on local tissues in prolonged period

Devices used to prevent or treat pressure ulcers
Devices to support pressure areasFlotation pads are pliable pads with a consistency like
body fat, which disperse pressure over a larger area. Pillows and bridging techniques lift the pressure site off the mattress and separate two points of pressure.
Devices to aid in turning a clientA Guttman bed rotates the client from prone to supine
positions and from side to side.Kinetic therapy continuously rotates the client 270
degrees every 3 minutes.
Devices to minimize or equalize pressureAlternating air mattresses made of polyvinyl air cells
are attached to a pump that inflates and deflates them every 3-7 seconds, alternating pressure points.
Water mattresses disperse and evenly distribute the client’s body weight.
High and low air loss bed allow deformation of bed surface to the body contours, thereby reducing tissue pressure below capillary closure. These beds also eliminate shear and friction and reduce moisture.
Reduce shear and friction
For bedridden clients, elevated the head of the bed to no more than 30 degrees.
clients must be positioned, transferred, and turned correctly. lifting rather than dragging

Protect skin of patients
keep the client’s skin and bedsheet clean and dry Clean,not soap ; daub ointments, Urine, stool, wound drainage;Vaseline or

Stimulating blood circulation of skin

Stages of Pressure Ulcer
Stage I :nonblanchable erythema of intact skin, the heralding lesion of skin ulceration
Stage :Ⅱ Partial thickness skin loss involves damage or necrosis of epidermis, dermis, or both
Stage :Ⅲ Full thickness skin loss involves damage or necrosis of subcutaneous tissue that may extend down to, but not through, underlying fascia
Stage :Ⅳ Full thickness skin loss with extensive destruction, tissue necrosis or damage to muscle, bone, or supporting structure such as tendon or joint capsule

Stage I Principle: eliminating risk factors or contributing factors to
pressure ulcers increasing turning frequency, avoiding local tissue pressed long
term, improving circulation, keeping bed linen clean, smooth, dry without oddment, reducing friction and shearing force, avoiding excretion and moisture stimulating to skin, increasing nutrition and enhancing immunity and so on.
