Flashcards in Soft Tissue Trauma Deck (22):
1

Soft Tissue includes

skin, fatty tissues, muscles, blood vessels, fibrous tissue, membranes, glands, and nerves

2

Skin Functions

(total surface area = over 20 square feet
three major layers- epidermis, dermis, and subcutaneous layer)
Protection
Water balance
Temperature Regulation
Excretion
Shock absorption

3

Epidermis

Outer layer of the skin
composed of dead cells, which are rubbed off and replaced
contains no blood vessels or nerves

4

Dermis

inner layer (second) of the skin found beneath the epidermis. Rich in blood vessels and nerves. also sweat glands, sebaceous (oil) glands, hair follicles.
if exposed to the outside world contamination and infection will occur

5

Subcutaneous Layer

layer of fat and soft tissues found below dermis
shock absorption and insulation are major functions of this layer

6

Closed Wound

an internal injury with no open pathway from the outside
usually results from impact of a blunt object
can be simple bruises, internal lacerations (cuts), internal punctures caused by fractures, crushing forces, or rupture of internal organs

7

Contusions

bruise
epidermis remains intact, but cells and blood vessels in dermis are damaged

8

Hematomas

swelling caused by collection of blood under the skin or in damaged tissues as a result of an injured or broken blood vessel

9

Open Wound

injury in which the skin is interrupted, exposing the tissue beneath

10

Abrasion

scratch or scrape
outer layer of the skin is damaged but not all the layers are penetrated

11

Laceration

a cut
often caused by an object with a sharp edge

12

Puncture Wound

an open wound that tears through the skin and destroys underlying tissues. can be shallow or deep.
perforating puncture wound has both an entrance and an exit wound

13

Avulsion

the tearing away or tearing off of a piece or flap of skin or other soft tissue.
term used also if an eye pulled from its socket or a tooth dislodged from its socket

14

Amputation

surgical removal or traumatic severing of a body part, usually an extremity

15

Burn Agents and Sources

Thermal, Chemical, Electrical, Light (typically involving the eyes), Radiation

16

Superficial Burn

First Degree burn
burn that involves only the epidermis
characterized by reddening of the skin and perhaps some swelling
common example: sunburn

17

Partial Thickness burn

Second Degree burn
burn in which the epidermis is burned through and the dermis is damaged
reddening, blistering, and mottled appearance

18

Full Thickness Burn

Third Degree burn
burn in which all the layer of the skin are damaged. usually areas that are charred black or areas that are dry and white

19

Determine the Severity of a burn

Agent or source of the burn
body region burned
Depth of the burn
Extent of the burn
Age of the patient
Other illnesses and injuries

20

Rules of Nines

method of estimating the extent of the burn. for an adult, each of the following areas represents 9 percent of the body surface: head and neck, each upper extremity, the chest, the abdomen, the upper back, the lower back and buttocks, the front of each lower extremity, and the back of each lower extremity. the remaining 1 percent is assigned to the genital region. for an infant or child. the percentages are modified so that 18 percent is assigned to the head, 14 percent to the lower extremity.

21

Rule of Palm

method for estimating the extent of a burn. The palm of the patient's own hand, which equals about 1 percent of the body's surface area, is compared with the patient's burn to estimate its size

22

Occlusive Dressing

any dressing that forms an airtight seal
