16
Q

Cardiovascular complications

A

Increased capillary permeability leading to:
- fluid loss
- decreased cardiac output
Capillary permeability returns to normal after 24 hours
Fluid replacement therapy helps manage intravascular fluid loss

17
Q

Heterotopic ossification

A

Etiology unknown
Most common in elbow, hips no shoulders
Symptoms; decrease ROM and increase point pain tenderness

18
Q

Neuropathy complications

A

Usually due to poor management (tightness of bandages and splinting)

19
Q

Why would amputation occur

A

Subdermal burns. Usually electrical burns

20
Q

Hypertrophic scar

A

Raised, red , rigid

21
Q

Keloid scar

A

Type of hypertrophic scar that extends beyond the boundary of original wound

22
Q

Types of pathological scars

A

Hypertrophic scar
Keloid scar
Scar contracture (scar bands)

23
Q

Initial management

A

Establish and maintain an airway
Prevent cyanosis, shock, and hemorrhage
Establish baseline data
Fluid replacement
Clean the patient and wounds
Examine injury
Prevent and manage any pulmonary complications

24
Q

Wound care

A

Inspect wound
Clean wound
Debridement of wound
Prevent injection

25
Permanent skin graft
Autografts- from patients own skin (commonly from thighs and back) - sheet graft -mesh great
26
Temporary graft
Allograft (from the same species) Xenograft (from another species)
27
Escharmatomies
Performed when Escher is restricting circulation
28
Physical therapy management
Prevent scar formation contractures bring them back to normal Healing Maximal ROM
29
PT Goals
Maximal function and minimal complications
30
Positioning and splinting
Minimize edema Prevent contracture Preserve function
31
AROM
Begin day of admission on all extremities and trunk Coordinate with pain medication and dressing changes Discontinue joints above and below skin graft for roughly 3-5 days
32
PROM
Perform when patient is not alert or able to follow commands Perform on children If patient cannot fully achieve active ROM Stress should be applied in a gentle, gradual and sustained fashion
33
Resistive
Monitor vital signs initially Proper hydration is vital Room temp may need to be adjusted
34
Conditioning
Same as resistive All exercises should be done
35
Ambulation
Begin as soon as possible Discontinue after LE skin grafting until safe to resume Use elastic wraps or TED stockings to minimize edema and stasis when upright, and to protect new graft
36
Scar management
Pressure Dressings Massage
37
Superficial burn
Erythema (just redness)
38
Partial thickness burn (epidermis and upper part of dermis)
Blistering (may heal without a scar)
39
Full thickness burn (epidermis and entire dermis)
Necrosis (will heal with scar)
40
Subdermal burn (epidermis, dermis and subcutaneous tissue)
Extensive surgical and therapeutic management necessary to return patient to some degree of function.
