PHTLS SetIf you see a cracked windshield in a MVC... What will the pt represent with? - ANS Bruised or
lacerated head or face. Brain injury, *cervical spine injury (always until proven otherwise),
tracheal injury.
If you see a deformed steering column in a MVC... What will the pt represent? - ANS 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? - ANS Bruised
abdomen, bruised knee, displaced 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? -
ANS Secondary anterior injuries, esp if the pt wasn't restrained. "Whiplash" injuries, *coup
contrecoup injury.
Phases of Deceleration - ANS 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 - ANS "Speed kills"- causes more damage than mass.
Seat Belt Use - ANS All arguments against seat belt use are unfounded.
Airbag Injuries - ANS 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 - ANS 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 - ANS Chest hits the steering wheel, head hits the windshield and the
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 - ANS 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 rib fractures.
Angular Impact in Motorcycle Crashes - ANS The motorcycle strikes an object, or another
vehicle at an angle so that the rider sustains direct crushing injuries to the lower extremity
between the object and motorcycle.
Motorcycle Crashes - ANS 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 rider's head.
Pedestrian Injuries - ANS Most pedestrian injuries occur at an intersection, at night. First, the
pedestrian is hit in the lower extremities with the car's 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 - ANS 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 - ANS 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,
causing spinal injuries "Don Juan Syndrome or Lovers Leap". 3) Surface- Snow vs. Concrete.
Blunt Trauma - ANS Refers to injuries in which the tissues are not penetrated by an external
object.
Penetrating Trauma - ANS Involves a disruption of the skin and underlying tissues in a small,
focused area. Most common cause of penetrating trauma- GSW.
Stab Wounds - ANS Severity of the stab wound depends on the anatomic area involved, depth
of penetration, blade length and angle of penetration.
GSW - ANS 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, are better able
to tolerate stretch, rather than the liver.
Entry Wound - ANS Characterized by the effects of initial contact & implosion. *As a general
rule, the entrance wound (usually funnel shaped)is always smaller than the exit wound.
