W4~ chapter 25: Trauma

What is the leading cause of death for people aged 1-44

Unintentional Traumatic Injuries

Traumatic Injuries vs Medical Emergencies

Traumatic Injuries: Physical Force applied to the body

Medical Emergencies: illness or conditions not caused by force

What is Index of suspicion?

the awareness/concern for possible underlying injuries

Is the speed of the fall more important or is height?

height

Is the speed of a car more important or its weight

speed

Work vs Kinetic Energy vs Potential Energy

Potential Energy: the product of mass; force of gravity as you move up; height

Kinetic Energy: Energy of a moving object

Work: Force acting over distance; abrupt stop

(MOI) Non Significant vs Significant Trauma

Non significant: 1 body part, fall with no unconsciousness
Significant: Multisystem trauma; common in falls, crash, wounds and stabbings

What is Blunt Trauma

Forces upon the body that do not penetrate the skin

What risks does bunt trauma pose for conditions?

You have to look very carefully for notable changes to have a high index of suspicion for internal bleeding/damage

How are Vehicular crashes categorized

based on the direction of force Frontal, Rear-End, T bone, Rollover, and Spins/ Rotational

In Frontal Crashes what are key evidence of trauma?

the supplemental restraint system, airbag deployment, front windshield +

In Rear-End Crashes what are key effects of trauma?

The whiplash which as car comes to a drastic stop, the passenger moves forward, then aggressively back

What is a key point of T-Bone Crashes? vs Lateral Whiplash

an awkward crash so its a common cause of death; medical condition where they hit against the side of a window

Rollover vs Rotational Crashes

Rollover: car is on its side; prepare life threatening injuries (2nd/3rd collisions)

Rotational: car spins in donuts out of control until its strikes something

How should you evaluate a pedestrian and car crash?

Assess the car speed and the patient severity; be aware of underlying injuries

How should you evaluate a bicycle and car crash?

evaluate bike position, patient condition (with leather); Helmet are important fir evaluating the impact of a head/ spinal cord injury

What are the 4 types of Motorcycle Crash impacts

Head-On Crash, Angular Crash, Ejection and Controlled Crash

When evaluating a scene consider:

The height of the fall, The type of Surface Shock, and The part of initial impact and where the path of energy is after

What is Penetrating Trauma

Trauma where physical entrance is visible

When evaluating Penetrating Trauma what should you evaluate?

Count the number of wounds (lets dr evaluate entrance and exit wounds)

Path vs Drag vs Cavitation

Path: Trajectory

Cavitation: rapid internal change via projectile

Drag: air resistance that disturbs the outer

Mass Double vs Velocity Double

Mass Double: energy doubles

Velocity Double: Energy Quadruples

What are the 4 blast injury types?

Primary blast Injuries, Secondary Blast Injuries, Tertiary Blast Injuries and Quaternary Blast Injuries

Primary blast Injuries vs Secondary Blast Injuries vs Tertiary Blast Injuries vs Quaternary Blast Injuries

Primary Blast Injuries: Injuries due to the blast waves itself

Secondary Blast Injuries: Injuries due to missiles being propelled by blast force

Tertiary Blast Injuries: Injuries due to impact with another object

Quaternary Blast Injuries: Collateral Injuries such as burns, crush injury, and toxic inhalation

Solid vs Hollow tissues in blast injuries

Hollow: Susceptible to air changes; most common in the air

Solid: Relative protected

Solid and Hollow Organs of the abdomen

Solid: Liver, spleen, pancreas, and kidneys

Hollow: Stomach, Large/ Small Intestine, and Bladder
