There are three types of burns - what are they?

Thermal
Electrical
Chemical

2

What burns have the following information related to them? Caused by conduction or convection, eg. hot liquid, fire or steam. Heat differential

Thermal

3

What burns have the following information related to them? Caused by passage of electrical current through body - entrance & exit wounds ex. lightening (TENS) Nasty- gets worse with time w/ time, circulatory problems, smooth muscle spasms

Electrical

4

What burns have the following information related to them? Caused by chemical compounds in contact with body - need to wash off ex. sulfuric acid, gasoline

Chemical

5

What are the layers of the Epidermis?

Stratum Corneum (flakes)
Stratum Granulosum (granular)
Stratum Spinosum
Stratum Basale

6

What layer of the Epidermis is where the UV protection and Vit. D. production and melanocytes produced.

Stratum Basale

7

What are the functions of the Epidermis?

Protection from microorganisms & UV
Vitamin D production
Temperature Reegulation (waterproof & pores for sweating)
Cosmesis (is the preservation, restoration, or bestowing of bodily beauty)

8

What are the layers of the Dermis?

Papillary
Reticular
(also rete Peg is a region in both Epidermis/Dermis that interlaces like fingers)

9

What is another name for the Dermis?

True Skin

10

What are the functions of the Dermis?

Provide nutrition to epidermis (diffusion)
Sensation (awereness and protection in exploration of environment)
Temperature regulation (sweat glands and fat in hypodermis)

11

How do you describe the layers of the Dermis?

Pappilary - finger - loose
Reticular - thick, woven, dense

12

What are the burn classifications (in order of depth?)

Epidermal Burn
Superficial Partial - Thickness
Deep Partial - Thickness
Full Thickness Burn
Subdermal Burn

13

Describe Epidermal Burns

Involves only epidermis (sunburn)
Red & slight edema
Desquamation = peeling
No scarring
Painful
*some epidermal cells live in dermis

14

Describe Superficial Partial Thickness

Involves Epidermis & upper portion of dermis (pappilary)
Blisters & very painful
brisk Capillary refill with compression
Minimal Scarring
Pop Out blisters (intact)
More pain that Deep Ptl thickness

15

Describe Deep-Partial Thickness

Involves epidermis and majority of dermis (pappilary and reticular)
Broken blisters, moderate pain and edema
Slow Capillary Refill
Broken (open) blisters
Less Painful that other prior two
Lots of swelling
As long as some dermis remains, you have epidemal cells

16

Describe Full-Thickness Burn

Complete destruction of epidermis, dermis & partial destruction of subcutaneous fat layer
No Capillary Refill
No pain - nerves destroyed
Eschar, minimal pain & requires graft
Dry, Rigid - some red in scabs
Dermis is gone
No blisters
Significant Scarring w/ skin graft

17

Describe Subdermal Burn

Complete destruction of epidermis, dermis & subcutaneous tissue
May involve muscle & bone
Charred
Skin Graft
No Blisters
Scarring - yes
No Capillary Refill
No pain

18

Characteristics at various burn depths - Healing

Skin graft needed for full-thickness and subdermal

19

Characteristics at various burn depths - Scarring

Distict scarring with skin grafts - moderate with Deep Partial Thickness - minimial with Superficial partial Thickness - No scarring with Epidermal

20

Characteristics at various burn depths - Pain

Maximum at superficial partial thickness then decreasing pain with increasing depth (no pain at full-thickness & subdermal)

21

Characteristics at various burn depths - Blisters

Intact blisters for superficial partial-thickness; broken blisters for deep partial thickness, no blisters for other depths.

22

Characteristics at various burn depths - appearance

Increasing edema for 1st 3 levels with redness in 1st two; eschar, dry, and rigid for full-thickenss; charred for subdermal

23

Characteristics at various burn depths - Blanching

Brisk capillary refill for 1st 2 levels; slow refill for deep partial thickness; no capillary refill for full thickness and subdermal

24

How can a deep partial-thickness burn later become a full-thickness burn?

Infection
10^5 Bioburden
10^7,8,9 - Lethal

25

How are the medical treatments for deep partial thickness burns and full-thickness burns different?

Deep partial thickness - 3-5 weeks w/out infection
new hair growth
thin epidermis - not as good though
Decreased oil glands
Decreased sensation
Decreased Rete peg region - more apt to sheer w/ force
have to pay attention to extra precautions - thin skin, easily abraided less nerves

26

What are the 3 burn wound zones - and which have reversible cell damage?

Zone of Coagulation - cells DEAD - most destructive
Zone of Statis - second ring - reversible with treatment
Zone of Hyperemia - third ring - reversible without treatment

27

What is the rule of 9's regarding adults?

Head/Arms - 4.5% each half
Trunk - 18% front/back
Legs - 9% front/back
Genitals - 1%
100% of body burned if all effected

28

What are the secondary systemic complications associated with severe burn injury?

Infection
Pulmonary complications
metabolis complications
heterotopic ossification
peripheral neuropathy
Cardiovascular - fluid shift from art/ven to lymphatic - interstitial space.

29

What's a neat way to think of your skin?

The skin is your nervous system exposed in the environment.
