1

3 layers of skin

Epidermis, dermis and subcutaneous tissue

2

what part of the epidermis is metabolically active

inner

3

A barrier that prevents loss of fluid by evaporation and loss of body heat

Dermis

4

layer of skin w/ blood vessels, nerves, sweat glands, appendages (allow you to regrow skin)

dermis

5

layer of skin that is mostly fat but also has skin appendages, blood vessels, and nerves

Subcutaneous layer

6

what happens w/ a first degree burn

Involves only the epidermis
Epidermal barrier remains intact
No blistering

7

2 types of second degree burns

superficial
deep

8

upper 1/3 of dermis is invovled

superficial 2nd degree burn

9

lower 2/3 of dermis is involved

deep 2nd degree burn

10

if there fluid loss w/ a superficial 2nd degree burn?

not, most barrier intake

11

how long does it take for a superficial partial-thickness burn to heal

10-14 days

12

dry and thickened burn that is red or white
can have high fluid loss and can get infected

deep second degree burn

13

healing time w/ 2nd degree burn (deep)

heal in 4-8 weeks on their own
better outcome w/ skin grafting

14

May look unburned skin
Can be white and waxy to completely black
Can be dark red, but dry and non-blanching
Leathery texture
non-painful

3rd degree (full-thickness) burn

15

tx for 3rd degree burn

full thickness skin grafts

16

a 3rd degree burn where Dermal proteins coagulate and contract is called what
causes skin to be tight

eschar

17

what is an Escharotomy

making an incision for skin to expand so
a person can breathe or save a limb

18

what are respiratory injuries

inhalation
aspiration from unconscious patients
bacterial pneumonia
pulmonary edema
post-traumatic pulmonary insufficiency
ARDS

19

are inhalation injuries more common outside or in an enclosed area?

enclosed area

20

what scenarios should you suspect an inhalation injury

History of closed space exposure
Perioral burns
Intraoral burns
Carbonaceous material in the oropharynx
Progressive hoarseness
Singed facial and nose hairs

21

when should you suspect CO posioning

Suspect in same patients that you suspect of inhalation injury + HA and mental status change

22

can pulse ox and PaO2 be normal in CO poisoning

yes

23

symptoms w/ CO poisoning

Asymptomatic – HA – dizziness – syncope – coma - death

24

treatment w/ CO poisoning

100% oxygen
may need intubation or hyperbaric chamber

25

what do you need to determine if CO poisoning

send off blood for CO levels

26

In trauma what do you want for fluid resuscitation?

2 large bore IV's
(14 or 16 gages)

27

when do you need to do a urinary cath for burns?

>20% TBS

28

what burns are used to determine total body surface area?

only 2nd (deep) and 3rd degree burns

29

what are considered major burns

partial thickeness >25% body adults >20% peds
full thickness burns >10% TBSA
2nd or 3rd involving- hands, feet, fact, perineum, genitalia, major joints
associated w/ inhalation injury
burns + fractures
electrical/ lightning/ chemical
circumferential burns
really young or old

30

what is the consensus formula

2-4 mLs X %TBSA (2nd and 3rd degree) x wt in kgs
give 1/2 of volume in first 8 hours
giver other 1/2 in remainder 16 hours
