  1. Chapter 5 Assisting Clients With Hygiene Section 6 Prevention and Care of Pressure Ulcers

  2. contents • Contributing Factors to Pressure Ulcers Formation • Prediction and Prevention of Pressure Ulcers • Treating and nursing pressure ulcer

  3. 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

  4. Pressure ulcer • 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.

  5. Contributing Factors to Pressure Ulcers Formation • Factor of pressure • Pressure • Friction • Shearing force • Moisture irritation to the Skin • Nutritional Status • Age • Fever (infection) • Orthopedic Devices

  6. Factor of pressure 垂直 压力 Pressure 剪切力 Shearing force 摩擦力 Friction

  7. Moisture irritation to the Skin • urinary and fecal incontinence • wound drainage • sweat

  8. Nutritional Status • Malnutrition • Protein malnutrition • Protein- energy malnutrition • Cachexia • Obesity • Dehydration • Edema

  9. 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.

  10. ★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.

  11. 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 • increased skin moisture irritation

  12. Orthopedic Devices • plaster, bandage, splint, retractor • reduce mobility of the client or of an extremity • friction • pressure

  13. Prediction and Prevention of Pressure Ulcers • Assessment • Patients With High Risk of Pressure Ulcers • Predicting Pressure Ulcers Risk • Common Pressure Ulcer Sites • Preventative interventions

  14. Patients With High Risk of Pressure Ulcers! • Clients with the neural diseases • Old people • Obesity • Debilitated and malnutrition • Edema • Pain • orthopedic devices • urinary and fecal incontinence • fever • quietive therapy

  15. Predicting Pressure Ulcers Risk • predictive instruments • the Braden Scale • the Norton Scale • the Gosnell and Knoll instruments

  24. Preventative interventions

  25. 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

  26. 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

  27. 翻身 Avoid pressure on local tissues in prolonged period • Turn the patients periodically • Protect bony prominence and support interspace • Use the devices right 支被架 气垫床褥

  28. Devices used to prevent or treat pressure ulcers Devices to support pressure areas Flotation 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 client A 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.

  29. Devices to minimize or equalize pressure Alternating 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.

  30. 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 • bedpan

  31. 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 zinc oxide • Incontinence; diaper

  32. Stimulating blood circulation of skin • range-of-motion,ROM • Warm water bath in bed: see disc • Check and massage skin • Local tissue massage • back rub: see disc

  33. Provide adequate nutrition • receive sufficient protein, vitamins (A, C, B1, B 5), and zinc

  34. Health education • Educate clients and care givers regarding pressure ulcer prevention

  35. Treating and nursing pressure ulcer

  36. 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

  37. 瘀血红润期(hyperemia, nonblanchable erythema ) • heralding lesion. • temporary circulation lesion • Manifestation: • Redness(lightly skin) • Red blue,purple hues (darker skin) • Redness, swollenness, heat, and pain

  38. 炎性浸润期(ischemic,inflamation ) • epidermis, dermis, or both • Gore,ischemic, • readness and swollenness enlarged;color: purple, not change with pressed;superficial abrasion, blister or shallow crater

  39. 浅度溃疡期(superficial ulceration) • subcutaneous tissue(superficial tissue) • Blister is torn,infection, ichor,necrosis and ulcer

  40. 坏死溃疡期(Necrotic ulceration) • Deep dermis, muscle, bone, tendon or joint capsule • Necrosis turn blue,ichor, septicopyaemia

  41. Treating pressure ulcer • Supportive or systemic measures: • providing adequate nutrition • Protein status • Hemoglobin • Controlling infection: • Body substance isolation and good hand washing technique • Local care of the wound

  42. Local care of the wound • 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. • Moist dressing • Toast light • Ban massage

  43. Stage Ⅱ • Principle:protecting skin and preventing infection • preventive measure followed • intensify care of blister • Small untorn blister: • big blister: see disc • draw out liquid in blister with sterile injector , unnecessarily scissoring pellicle, and then sterilize the surface and cover it with sterile dressings. • ultraviolet or infrared treatment.

  44. Stage Ⅲ • Principle:keeping cleanliness of the ulcer area • Eliminate pressure,keep clean • physical therapy: Goosenecked light • Moisture-retentive dressings • transparent films, hydrocolloid dressing, and hydrogels • 新鲜的鸡蛋内膜、纤维蛋白膜、骨胶原膜等贴于创面

  45. Stage Ⅳ • Principle:keeping cleanliness of the ulcer area, debriding necrotic tissue, keeping drainage smoothly, promoting acestoma growing

  46. Stage Ⅳ • Preventive measures • Clean and rinse ulcer area: see disc • with sterilized normal saline or 1:5000 Furacilin solution, then covered with sterilized Vaseline gauze or dressings. Metronidazole dressing or be daubed with Sulfapyridine Argentums or Furacilin. • cleansed with 3% Hydrogen Peroxide solution for deep ulcer. • keeping drainage smoothly • oxygen therapy • Surgery: debride necrotic tissue, skin grafting and skin flap • Chinese traditional medicine
