Q&A | Guaranteed Success
• If you see a deformed steering column in a MVC... what will the pt
represent with? -✓✓Bruised neck, bruised chest. Sternal or rib fracture,
flail chest, myocardial contusion, *pericardial tamponade,
pneumo/hemothorax, aortic tear.
• If you see a deformed dashboard in a MVC... what will the pt represent
with? -✓✓Bruised abdomen, bruised knee, misplaced kneecap. Ruptured
spleen, liver, bowel, diaphragm. Fractured patella, dislocated knee,
*femoral fracture, dislocated hip.
• If you see the rear end of the vehicle is damaged in a MVC... what will
the pt represent with? -✓✓Secondary anterior injuries, esp if the pt
wasn't restrained. "Wiplash" injuries, *coup contrecoup injury.
• Phases of Deceleration -✓✓1) Deceleration of the vehicle, occurs
when the vehicle strikes another object & comes to a stop. 2)
Deceleration of occupant, which starts during sudden braking &
continues through the whole crash. 3) Deceleration of internal organs,
that consist of internal organs that continue forward momentum until
they're stopped by anatomical restraints. 4) Secondary collisions, which
occur when a vehicle occupant is hit by objects moving within the
vehicle (loose objects). 5) Additional impacts, that the vehicle may
receive when it is hit by a second vehicle or is deflected into another.
• Velocity -✓✓"Speed kills"- causes more damage than mass.
• Seat Belt Use -✓✓All arguments against seat belt use are unfounded.
,• Airbag Injuries -✓✓Common injuries include abrasions to the face,
chest and arms. Minor corrosive effects can occur because of the
cornstarch on the airbag, and it may irritate the skin.
• Down and Under Pathway -✓✓Occupant slides under the steering
wheel or the dash. The knees hit the dashboard, and transmit energy up
the leg, to the femur/pelvis. If the feet are locked in place, it can cause
femur fractures.
• Up and Over Pathway -✓✓Chest hits the steering wheel, head hits the
windshield and anterior portion of the throat hits the top of the steering
wheel. Can cause significant head and neck injuries.
• Head on Impact in Motorcycle Crashes -✓✓Head on impact-
motorcycle strikes another object and stops its forward motion, while the
rider continues forward motion until stopped by outside force. This
causes the rider to go over the handlebars, which causes femur fractures,
and tib fractures.
• Angular Impact in Motorcycle Crashes -✓✓The motorcycle strikes an
object, or another vehicle at an angel so that the rider sustains direct
crushing injuries to the lower extremity between the object and
motorcycle.
• Motorcycle Crashes -✓✓With any motorcycle crash, the helmet should
be removed carefully if airway management techniques cannot be
performed with the helmet in place or the helmet doesn't fit properly on
the riders head.
• Pedestrian Injuries -✓✓Most pedestrian injuries occur at an
intersection, at night. First, the pedestrian is hit in the lower extremities
with the cars bumpers. Second, the pedestrian is thrown on the top of the
car (resulting in brain injuries, and pelvic fractures. Third, the pedestrian
, hits the ground or some other object after rolling off the top or the side
of the vehicle.
• Waddell Triad -✓✓Refers to the pattern of automobile pedestrian
injuries in children and people of short stature; 1) bumper hits the
pelvis/femur instead of the knees, 2) the chest & abdomen hit the grill or
low on the hood of the car (sternal & rib fractures), 3) the pt's face hits
the hood, then flies back, and hits the ground.
• Fall Severity Factors -✓✓1) Height- determines the velocity of the fall.
A fall greater than 15 feet or 2.5-3 times the pt's height will have a
greater injury & higher rate of death. 2) Position- children usually land
on their heads (more mass), and adults tend to try to land on their feet,
cause spinal injuries "Don Juan Syndrome or Lovers Leap". 3) Surface-
Snow vs. Concrete.
• Blunt Trauma -✓✓Refers to injuries in which the tissues are not
penetrated by an external object.
• Penetrating Trauma -✓✓Involves a disruption of the skin and
underlying tissues in a small, focused area. Most common cause of
penetrating trauma- GSW.
• Stab Wounds -✓✓Severity of the stab wound depends on the anatomic
area involved, depth of penetration, blade length and angle of
penetration.
• GSW -✓✓The most important factor for the seriousness of a gunshot
wound is the type of tissue through which the projectile passes. Tissues
of high elasticity like muscle, is better able to tolerate stretch, rather than
the liver.
