Flashcards in Black Saturday Deck (14):
1

T or F: nerve endings penetrate into the epidermis?

False

2

Where are stems cells located for regeneration of the epidermis?

Hair follicles

3

Eschar

A slough or piece of dead tissue that is cast off from the surface of the skin, particularly after a burn injury

4

1st degree burn

only superificial layers of the epithelium (cornified and granular layers) are affected: skin is painful, red, swollen, and flakey; usually heal without complication

5

2nd degree burn (superifical)

Deeper layers of epidermis are affected (granular & spinous layers but minimal basal cell layer involvement; pain and tactile receptors remain: heal with minimal scarring 14-17 days)

6

2nd degree burn (deep)

All of the epidermis, including basal cell layer is affected; pus forms under the necrotic parched sloughing eschar; there is minimal pain; the only germinal cells remaining are deep within the hair follicles (in the dermis); with care these may heal within 3-4 weeks, usually with extensive scarring, grafts often indicated

7

3rd degree burn

Loss of epidermis and dermis, wounds often appear white or black with eschar formation and no pain; frequently complicated by wound infection and generalised sepsis; extensive scarring occurs and grafting usually required

8

4th Degree Burns

All skin and some underlying fascia, muscle ligaments and/or bone affected

9

What are some consequences of third degree burns?

Hypovolaemia, increased capillary permeability, hypoproteinaemia

10

Above which portion of the body are burns considered lethal?

20%

11

Acute systemic consequences of burn injuries (name 2)

Shock and dehydration

12

What percentage of the koala's body surface is taken up by its trunk (excluding the head)?

40%
