Q

Burns - rule of nines

A

Based on an atomic region

24
Q

Pt w/ central facial burns

A

Should be evaluated for hospital admission

25
Q

Burn - respiratory - neck or chest eschar

A

May cause restricted chest expansion

Eschar onto my or fasciotomy may be required

26
Q

Burns - respiration - Pulm edema

A

Fluid rescucitation may cause fluid overload
May be candidate for hyperbaric oxygen
Pt will be monitored in burn unit for respiratory changes during fluid rescuscitation

27
Q

Burns - renal

A

Urine output closely monitored, generally 30-50 ml/hr
Due to decrease in circulation and BP, kidney fix decrease in burn injury
Glomerular filtration rate decreases, then will return to normal w/ adequate fluid resuscitation

28
Q

Burns - renal failure

A
Uncorrected burn shock
Hemorrhage
Electrolyte imbalance
Sepsis 
CHF
29
Q

Burns - GI

A

Fluid resuscitation
Early enteric nourishment w/ staged food intake
Mobility
Abx use alteration of bacterial flora in intestines

30
Q

Burns - metabolism

A

Burn trauma increases metabolic demands
Ketoacidosis
Rapid weight loss
Nutritional supplements, close nutritional monitoring to promote burn healing

31
Q

Most common cause of mortality in burn pts

A

Infection

32
Q

Key to preventing infection - burns

A

Isolate burn pts to reduce hospital aquifer infections
Staff wear protective garments
Sterile procedures

33
Q

Burn survival rate estimate - revised baux score

A

% mortality = pt age + %TBSA (+17 for inhalation injury)

34
Q

Burn tx

A
Initial stabilization and triage
Med management
Local burn tx 
Moisture - tendons moist
Rehab
35
Q

Initial burn tx

A

Stabilize airway, breathing and circulation
-check of resp distress and evidence of smoke inhalation
Check carotid pulse
Eval depth and extent of burn injury
Remove all burned clothing and foreign material
Transfer to burn unit f needed
Appropriate abx dressing as needed

36
Q

Fluid resuscitation for burns

A

W/in 2 hours for burns >20% TBSA, use parkland or brooke formula

37
Q

Burn admission criteria

A

<10% TBSA
3rd degree, electrical, chemical
Inhalation
Will require social/emotional or long term rehab
Comorbidities that complicate management
W/ concomitant trauma
In children where pediatric care is not available

38
Q

Local burn tx

A
Debridement if necrosis present
Appropriate dressings
Negative pressure wound therapy as needed
Biosynthetic dressings
Skin grafting
39
Q

Biobrane - pros

A
Biosynthetic dressing
Non reactive
Readily available for burn centers
Less pain for pt
Spares skin grafts
40
Q

Biobrane cons

A

Very extensive

41
Q

SJS

A

<10% TBSA

Death rate 1-5%

42
Q

TEN

A
>30% TBSA
Death rate 25% in adults
Large amount of fluid and electrolyte loss
Infection risk 
Possible organ failure
