Mechanism of Injury and Kinetics of Trauma Flashcards
How much time should you spend on scene?
LESS is BETTER but 10 minutes or less
What is the Law of Inertia?
object in motion will stay in motion unless it is struck by another object
What aspect is critical in the kinetics of trauma and why?
SPEED! can generate energy that affects the impact
What is the “3 Collision Concept”?
vehicle hits another object = body hits inside vehicle = internal organs hit walls of body
What is the injury pattern in Head-On Collisions?
head, neck and spinal trauma
What is our main worry with Head-On Collisions?
internal damage
What is considered definitive care?
surgery or hospital
What are the 2 main kinds of mechanisms of injuries?
blunt injuries and penetrating injuries
What is the injury pattern in Lateral Impact Collisions (T-Bone)?
the force coming at one direction causes the body to move at a C-shape formation
What are the most common body parts to be injured due to a Lateral Impact Collision?
femur and pelvic fractures
What occurs with the body during a Rear Impact Collision?
neck can hyperextend due to the whipping of the head/neck
What is the injury pattern that tends to occur with Rollover Collisions?
multi-system trauma
What is a multisystem trauma?
mix of life-threatening and distracting injuries
Why are safety belts important?
ejections can increase chances of death
What are “crumple zones”?
parts of the car that are meant to absorb the impact = amount of impact is decreased
What should we worry about with airbags?
can deploy even if car is off
What should you examine when it comes to Auto vs. Bike Incidents?
the bike, helmet and other signs of damage
What are the 3 things to consider during your scene size up when responding to Collision incidents?
determine type of collision | look for evidence of high-energy transfer | maintain a high index of suspicion
Where will you take patients that have been involved in a collision?
Trauma center
What are the 3 things you need to note when it comes to Fall incidents?
distance or MOI of fall | anatomic area impacted | surface of falls
What are the 2 types of penetrating injuries?
gun shot wounds and stab wounds
What must you look for in gun shot wounds?
entrance and exit wounds
What makes GSW serious?
bullets can bounce off of things in the body (ie: bones) and can change direction
What do we do with penetrating injuries due to an impaled object?
stop the bleed | stabilize object in one place (DON’T remove it)
How would you dress/stop the bleed of impaled objects?
use bulky dressings
What is the exception where we can remove an impaled object?
if it impairs with CPR or obstructs airway/ventilation (stop bleed first)
What is the concern with Bombing incidents?
there is often a secondary explosive device
