Trombly- BURN Flashcards
Anti-deformity positions
Positions opposite to common patterns of deformity used to prevent contractures.
Blanch
Apply sufficient pressure to interrupt blood flow temporarily: an assessment of capillary flow rate.
Deep partial-thickness burn
Thermal injury that destroys cells from the epidermis to the deep dermal layer.
Debride
Remove eschar and loose or necrotic tissue to prevent infection and promote healing.
Dermis
Layer of skin below the epidermis that contains blood vessels, nerve endings, hair follicles, and sweat and oil glands; supports the regrowth of new epithelial tissue.
Epidermis
Most superficial layer of the skin; acts as a barrier. It is continually sloughed and replaced.
Eschar
Burned tissue.
Full-thickness burn
Thermal injury in which the epidermis
and dermis are destroyed.
Superficial burn
Thermal injury that involves only cells in the epidermis.
Superficial partial-thickness burn
Thermal injury in which the epidermis and upper portion of the dermal layer are destroyed.
Wound contracture
Part of normal healing in which myofibroblasts in the wound bed contract to minimize the skin defect
Z-plasty
Surgical procedure in which a Z-shaped incision is made and tissue is transposed to increase tissue length
Superficial burns
- damage cells only in the epidermis.
- These injuries are painful and red.
- They heal spontaneously within approximately 7 days and leave no permanent scar
Superficial Partial-Thickness Burns
damage cells in the epidermis and the upper level of the dermis.
The most common sign of a superficial partial-thickness burn is in- tact blisters over the injured area
These injuries are also painful because of the irritation of the nerve endings in the dermal layer. Superficial partial-thickness burns heal spontaneously within 7–21 days and leave minimal or no scarring
Deep partial-thickness burns
cause cell injury in the epidermis and severe damage to the dermal layer
These injuries appear blotchy, with areas of whitish color interspersed throughout the wound
The injury site is painful.
Pressure sensation is intact, but light touch is diminished
Spontaneous healing of deep partial- thickness burns is sluggish (3–5 weeks) because vascularity in the dermal layer is impaired.
Therefore, the risk of significant scarring is increased For this reason, deep partial thickness burns are often grafted to expedite healing and minimize scarring.
Full-Thickness Injury
In a full-thickness injury both the epidermis and the dermal layer are destroyed
These wounds appear white or waxy and are inherently insensate because of the complete destruction of the dermal nerve endings
Full thickness burns require surgical intervention, such as skin grafting since there are no dermal elements to support the regrowth of epithelial tissue. Some burns, such as electrical burns, may damage structures below the dermis, including subcutaneous fat, muscle, or bone.
RULE OF NINES
A commonly used technique to determine burn size in adults
Lund Browder = To determine burn size in children and infants, a modification of this technique chart
The percentage of total body surface area (TBSA) that has been burned is used for the following:
• Calculating nutritional and fluid requirements
• Determining level of acuity to establish the level of medical treatment needed
• Classifying patients for use of standardized protocols

Medical Management
- This may include fluid resuscitation, establishment of adequate tissue perfusion, and achievement of cardiopulmonary stability.
- Associated injuries, such as fractures, are evaluated and treated during this time.
Inhalation Injury
Damage to the upper airway as a result of inhaling either hot particles or nox- ious gases results in an inhalation injury.

Escharotomy and Fasciotomy
Circulation can be compromised when burn injuries girdle a body segment. This is due to the inelasticity of the eschar (burned tissue) combined with increased internal pressure within fascial compartments. Local increase in pressure in the extremities compresses blood vessels and reduces blood flow (Sheridan et al., 1995). Symptoms of increased compartmental pressure include paresthesias, coldness, and decreased or absent pulses in the extremi- ties. In the trunk, inelastic eschar can act as a corset, limit- ing lung expansion and preventing adequate respiration. In both cases, surgical intervention (escharotomy and/or fasciotomy) is required to relieve the pressure and prevent tissue death. An escharotomy is a surgical incision through the eschar, whereas a fasciotomy is a deeper in- cision extending through the fascia. Unless exposed ten- don is present, the escharotomy region can be mobilized during therapy.
Dressings
After the initial burn assessment, the nursing staff applies dressings. The functions of dressings include protecting the wound against infection, maintaining contact be- tween the topical agent and the wound, superficially de- briding the wound, and providing comfort for the patient (Grigsby deLinde & Miles, 1995). Debriding is the removal of devitalized tissue from the wound site. Types of topical agents vary widely, although most are wide-spectrum antimicrobials. Examples include mafenide acetate (Sulfamylon), silver sulfadiazine (Silvadene), and 0.5% silver nitrate solution (Duncan & Driscoll, 1991). As a rule, the nursing staff changes the dressings; however, by peri- odically participating in dressing removal and application, the occupational therapist makes opportunities to view the healing wounds. This allows the therapist to monitor healing and adjust the therapy program accordingly.
Infection Control
One of the functions of the skin is to act as a barrier against infection (Falkel, 1994). Therefore, a patient with a burn injury is susceptible to infection. It is essential that all staff, family, and visitors adhere to infection control procedures. This includes frequent hand washing, use of gloves when necessary, and avoiding cross-contamination through instruments and equipment (Procedures for Practice 45-1).
Contracture Formation
Patients with burn injuries are at significant risk for con- tractures. Wound contracture, a normal physiological response to an open wound (Greenhalgh & Staley, 1994; Staley, Richard, & Falkel, 1994), combined with prolonged immobilization, creates an opportunity for permanent soft tissue contracture. Contractures tend to occur in pre- dictable patterns, usually flexed, shortened positions (e.g., elbow flexion, shoulder adduction, knee flexion) and can considerably limit the patient’s ability to perform activities of daily living. Example decrease elbow extension may limit the patient’s ability to dress.
Procedures
Hand Washing
Hand washing is the easiest and most effective thing you can do to prevent infections for you and your patients.
When to Wash
• Before and after all patient contact
• After removing gloves used to perform a task involving contact with blood, body fluids, or infectious material
• After handling possibly infectious devices or equipment
• Before and after preparing and eating food
General Procedure
• Dispense paper towel
• Push up long sleeves
• Wet hands and wrists
• Apply antiseptic solution or soap
• Use friction to clean between fingers, under nails, and palms and backs of hands; effective scrubbing lasts at least 20–30 seconds
• Rinse hands and towel dry
• Turn off faucet using paper towel
• Dispose of paper towel in appropriate trash barrel
• Waterless hand cleaner can be used until hand washing facilities are available
Occupational Therapy Assessment During the Emergent Phase
During the emergent phase, the occupational therapist per- forms a screen of the patient’s needs. A full evaluation is de- ferred until after the emergent phase, when the patient is more medically stable. During the screen, the therapist notes the distribution of the burn and which joints are in- volved. This allows the occupational therapist to establish an appropriate splinting and positioning program. It is also during this time that the therapist begins collecting infor- mation regarding the patient’s functional status before ad- mission, including individual interests and social supports.
Occupational Therapy Intervention During the Emergent Phase
Occupational therapy in the emergent phase focuses on the prevention of early contracture formation through the use of splints and positioning programs. It is ideal to ini- tiate occupational therapy intervention as early as 24–48 hours after burn because collagen synthesis and contrac- ture formation begin during the initial response to ther- mal injury (Evans & McAuliffe, 1995; Institute for Healthcare Quality [IHQ], 1997).
Splinting
Ideally, splints are fabricated and applied in the initial visit, and a positioning program is established and commu- nicated to the team. Table 45-1 describes common contracture patterns, anti-deformity positions, and appropriate splints. Generally, any joint involved in a su- perficial partial-thickness injury or worse has the potential for contracture and is usually splinted. Splint wearing times are determined by the patient’s ability to use the involved extremity. That is, a decrease in active movement indicates the need for increased splint wearing time. For example, a heavily sedated patient cannot perform active movement and, therefore, requires splinting at all times except for ther- apy and dressing changes. An alert patient who can use his or her affected extremity for functional tasks, such as self- feeding or prescribed exercises, may require the use of splints only at night. Splints are applied over the burn dress- ing and secured with either gauze wrap or Velcro straps.
