Flashcards in Burn Injuries Deck (29):
1

Account for 85% of total burn injuries

Scald burns

2

Scald burns are most prevalent in what age group

<4 y/o

3

Leading cause of hospitalization for burns

Scald burns

4

MC injured site in burn injuries

Hands

5

Major cause of morbidity and mortality in house fires in cases of burn injuries

Anoxia

6

Characteristics of burns that should raise the suspicion of child abuse

1) "Glove or stocking" pattern 2) Single-area deep burns on the trunk, buttocks, or back 3) Small, full-thickness burns (cigarette burns) in young children

7

Burns that prompt hospitalization

1) >10-15% TBSA 2) Smoke inhalation 3) High-tension voltage 4) Suspected child abuse or neglect

8

Burns that require IV fluid resus

1) >15% TBSA 2) High-tension and electrical injuries (to ensure forced alkaline diuresis in case of muscle injury/rhabdo to avoid renal damage)

9

Burn degree: Epidermis ONLY

1st

10

Burn degree: Entire epidermis and variable portion of dermis

2nd

11

Burn degree: Destruction of entire epidermis and dermis, leaving no residual cells to repopulate damaged area

3rd/full thickness

12

Burn degree: Painful

1st

13

Burn degree: No blistering

1st

14

Burn degree: Vesicle and blister formation

2nd

15

Pain of first degree burns resolves within

48-72 hrs

16

Rule of nines used to estimate BSA may be used only in children of what age

>14 y/o

17

The rule of palm may be used to estimate BSA for burns that involve

Small burns (<10% BSA)

18

Rule of palm

Wrist crease to finger crease in the child = 1% of the child's BSA

19

T/F For most children, the Parkland formula is an appropriate starting guideline for fluid resus

T

20

Parkland formula

4cc/kg/%BSA using LR; half of the fluid given over the 1st 8 hrs from onset of injury and remaining fluid given at an even rate over the next 16 hrs

21

Oral supplementation may start as early as ___ after burn

48 hours

22

T/F Mortality related to burn injury is NOT associated with toxic effect of thermally injured skin

T

23

Mortality related to burn injury is ASSOCIATED with

1) Metabolic and bacterial consequences of a large open wound 2) Reduction of patient's host resistance 3) Malnutrition

24

Depending on the time since the burn, children with a burn of 40% of TBSA require BEE approx ___% higher than predicted for age

50-100%

25

Caloric requirement of burn patients

~1.5x BMR

26

Protein requirement of burn patients

3-4g/kg/day

27

3 pulmonary syndromes of burn injuries

1) Early CO poisoning, airway obstruction, and pulmonary edema 2) ARDS at 24-48h or later 3) Late complications (days to weeks; eg pneumonia and pulmonary emboli)

28

Minor electrical burns usually occur as a result of

Biting on an extension cord

29

Voltage of high-tension electrical wire burns

>1000V
