PROPER POSITIONING, TURNING, AND DRAPING Flashcards
Positioning
arrangement of body parts in relation to one another
technique of placing the patient safely, comfortably, and effectively
Reasons for Positioning
prepare pt to gain access for part in the body
stability and support
relieve pressure to prevent bedsores
optimize organ system function
optimal aligned position
prevent contractures
Interval of positioning
every 2 hrs
Goals for proper positioning
- prevent contractures
- provide comfort
- provide support and stability
- provide access and exposure
- promote efficient function
- relieve excessive pressure
Effects of Immobilization
reduced cardiac efficiency
redistribution in body fluids
pulmonary deconditioning and dysfunction
stagnation of urine and incomplete bladder emptying
gastrointestinal dysfunction
NS affectation
electrolyte changes
hormonal disorders
Deconditioning Syndrome
reduced functional capacity of body system/s
treatment as a separate entity from the disease itself
affects integumentary, musculoskeletal, cardiovascular pulmonary, genitourinary, gastrointestinal, and nervous system
Effects of Immobilization on Integumentary System
pressure sores/ bed sores
Pressure Sores/ Bed Sores
normal capillary pressure: 30 mmHg
greater external pressure than normal capillary pressure
occlusion of blood flow –> ischemia –> necrosis
ischemia: no blood supply
necrosis: cell death
bony prominences are prone to injury
Extrinsic Factors to Skin Breakdown (Pretty French Skirts Hide In Redon)
- pressure
- friction
- skin maceration
- hydration status (important to note)
- infection in the area
- reduced activity
Intrinsic Factors to Skin Breakdown (Genie Said Bring Nuts Here Lazy Aladdin)
- general health
- skin condition
- body build and composition
- nutrition status
- hydration status
- location of wound
- adequate blood flow to wound
How to Check Intrinsic Factors to Skin Breakdown
ocular inspection
subjective: ask pt or people involved
objective: IE, general systems review, imperative to check signs of pressure
Bedwridden
unable to go out of bed due to injury (immobilization)
Bedbound
- constraints or contractions that bind pt to the bed
- pt with monitors/ attachments/ intubations
- medical orders/ doctor’s advice
Bedfast
pt who are strong, able, and are allowed to get out of the bed
Common Areas for Pressure Sore Formation During Supination
back of head
shoulder blade
lower back
bone prominence of elbow
heel
Common Areas for Pressure Sore Formation During Sidelying
ear
shoulder
lateral aspect of elbow
lateral aspect of hip
bony areas between knees and ankles
Common Areas for Pressure Sore Formation During Wheel Chair Sitting
back of head
shoulder blade
lower back
hip
sacrum
underside and back of heel
Common Areas for Pressure Sore Formation During Long Sitting
back of head
shoulder blade
lower back
sacrum
heel
Bed Grading in Pressure Sores
Grade 1: erythema- redness, skin intact and does not blanch in pressure
Grade 2: superficial ulceration that extends to dermis (skin loss, moist, pink, no necrotic tissue, partial thickness wound, reversible if treated)
Grade 3: ulcer advances to subcutaneous tissue (full thickness wound, necrosis, undermining, infection)
Grade 4: ulcer affecting muscle/ fascia
Grade 5: extensive ulcer with extensions into bursa of joints/ body cavities
Contracture Formation in Musculoskeletal Formation
adaptive shortening of muscle resulting to LOM
shortening and tightening of skin, muscle, fascia, and joint capsule
Factors Affecting Contracture Formation
- duration of immobilization
- limb position
- mobilization of joint
Decrease in Muscle Strength and Size
muscle loss:
1-3% per day
10-15% per week
50% in 3-5 weeks
muscle size may shrink to 50% of its original size in 2 months: atrophy
Contracture and Atrophy: Depletion of Biochemical Components
decrease in oxidative enzymes
Type I muscle fibers more subject to immobilization atrophy
decrease fuel/ energy sources
Baseline Measure
anthropometric measures using a tape measure, measure from medial tibial plateau to the bulkiest part of thigh
Chronic Atrophy
guttering of hands
loss of muscle components at hands
flattening of eminences
denervation of radial or ulnar nerve
Immobilization Osteoporosis
Wolff’s Law
-bone morphology and density are dependent upon the forces that act on the bone
- immobilized pt: decrease in stress on their bone due to lack of activity
-decreased bone tissue (bone mass) per unit volume (bone density)
- decreased bone mass is accompanied by a decrease in mineral content
- more susceptible to fracture
Degenerative Joint Disease / Osteoarthritis
joint loses its normal lubrication needed for joint nutrition
Cardiovascular System
Postural/ Orthostatic Hypotension
impaired ability of the circulatory system to adjust in the upright position
completely lost after 3 weeks
retraining would take 20-72 days
decrease on venous return from LE
decrease filling of left ventricle
decrease cardiac output
decreased cerebral perfusion (blood to the brain)= dizziness or syncope
key determiner: BP
Intervention on constrained pt who got unconscious while gradually tilting them upright
bring the pt flat on bed
ankle pumping for 2-3 mins straight
purpose: to increase cerebral perfusion and venous return, and to retrieve consciousness of pt
Signs and Symptoms of Orthostatic Hypotension
tingling, burning in the LE
light headedness, dizziness, fainting, vertigo
sweating (cold sweat)
pallor
increased pulse rate (> 20 bpm)
decreased systolic blood pressure (> 20 mmHg)
decreased pulse pressure
Reduced Cardiac Efficiency
HR progressively increased by 0.5 bpm/ day; 12-13 bpm in 10 days (immobilization tachycardia)
in 3 weeks, 25% decreased in cardiac volume performance
Resting HR of Sedentary Person Compared to Athletes
higher since they require more force to produce efficient cardiac output
Redistribution of Body Fluids
decrease in plasma volume –> increase in RBC –> increased blood viscosity –> increase thrombus formation (clot in big veins)
Thrombus
blood clot in big veins
calf veins is the common side d/t dec muscle pumpling
Embolus
traveling thrombus thru venous circulation
Respiratory System
decrease in lung volume
decrease diaphragmatic movement and chest expansion
contracture formation of intercostal muscles and costal joints
accumulation of secretions in lungs
leads to atelectasis (lung collapse) and pneumonia
Genitourinary System: Stagnation of Urine and Incomplete Bladder Emptying
voiding is difficult in supine position (needs gravity)
promotes kidney stone formation and UTI (urine is septic)
Gastrointestinal System
decrease in appetite
atrophy in intestinal mucosa and glands
slower rate of absorption
greater gas intake compared to food intake
constipation and fecal impaction
