1

golden hour

the first 60 minutes following a serious traumatic event, during which prompt medical treatment may prevent death.

1

index of suspicion

when evaluating a patient who has sustained trauma, the initial impression of what could be injured and how bad the injury is, based on the mechanism of injury.

2

injury pattern

a combination of injuries commonly seen in a patient based on the mechanism of injury.

3

kinematics

the branch of mechanics that studies the movement of body segments without consideration given to its mass or the forces making it move.

4

kinetic energy

the energy generated by a body in motion; mathematically expressed as mass _ velocity.

5

trauma

physical injury caused by an external force.

6

trauma center

a specialized hospital providing 24-hour trauma care, including stabilization, critical care, subspecialty care, and nursing care.

7

trauma surgeon

a physician who specializes in trauma care.

8

amputation

the complete or nearly complete separation of a body part or limb.

9

bandage

a strip or roll of gauze or other material used for wrapping or binding a body part.

10

burn

a lesion of the skin caused by thermal or frictional heat, chemicals, electricity, or nuclear radiation.

11

closed injury

damage beneath the skin or a mucous membrane from trauma while the overlying skin remains intact.

12

compartment syndrome

a condition in which the swelling of injured muscles within their connective tissue coverings causes pressure that can damage tissue and cut off blood flow.

13

compression dressing

an occlusive dressing that applies some pressure to a bleeding wound; it should not compromise circulation, movement, or sensation distal to the wound.

14

crush injury

compression injury in which a great amount of force is applied to the body.

15

dermis

the inner layer of the skin; contains hair follicles, sweat glands, nerve endings, and blood vessels.

16

dressing

any material (preferably sterile) used for covering and protecting a wound.

17

ecchymosis

a bruise; discoloration of the skin associated with a closed wound; signifies bleeding within the skin.

18

epidermis

the outer layer of skin that act as a watertight protective covering.

19

exsanguination

massive blood loss resulting in death; the process of bleeding to death.

20

extravascular

outside of a blood vessel.

21

hematoma

an extravascular collection of blood within the body's tissues or in a body cavity.

22

hemorrhage

the escape of blood from the vessels; bleeding.

23

hemostatic dressing

a surgical gauze/mesh impregnated with a material that stops arterial and venous bleeding in seconds.

24

impaled object

a foreign object that remains in the body in a puncture wound.

25

incision

cut that has clean, smooth edges.

26

occlusive dressing

dressing made of Vaseline gauze, aluminum foil, or plastic wrap that prevents air and liquids from entering or exiting a wound.

27

open injury

an injury in which a break in the skin or a mucous membrane exposes deeper tissue to potential contamination.

28

pressure dressing

a dressing that closes bleeding blood vessels by compressing the wound.

29

puncture

a penetrating wound resulting from a sharp, pointed object.

30

subcutaneous tissue

tissue between the dermis and the fascia overlying the muscle; contains fat, nerves, and blood vessels.

31

subungual hematoma

a painful extravascular collection of blood under a nail.

32

tourniquet

an instrument that when tightened around an arm or leg temporarily arrests the flow of blood through a large artery.

33

universal dressing

sterile, soft, highly absorbent, individually wrapped dressing that provides superior padding and protection for major wounds; usually measures 12 inches by 30 inches; also called trauma dressing.

34

alternating current (AC)

electrical current that periodically flows in opposite directions.

35

chemical burn

a burn caused by a caustic substance, such as an acid or a base.

36

direct current (DC)

electrical current that flows in one direction only.

37

electrical current

a stream of electricity that moves along a conductor.

38

first-degree burn

a burn that affects the epidermis only, causing reddening of the skin and mild edema but no blisters.

39

fourth-degree burn

a burn that extends into muscle and bone.

40

full-thickness burn

a third-degree or fourth-degree burn.

41

partial-thickness burn

a second-degree burn.

42

scald

an injury caused by a hot liquid or a hot, moist vapor.

43

second-degree burn

a burn that affects the epidermis and the dermis and results in blisters.

44

superficial burn

a first-degree burn.

45

thermal

pertaining to heat.

46

third-degree burn

a burn that destroys the epidermis and the dermis and extends into the subcutaneous tissue.

47

volt (V)

a unit of electric potential or electromotive force, equal to 1 watt per ampere or 1 joule per coulomb.
