-where did it go?
-what injuries are likely?
2 q's to ask in GSW - ANSWER - caliber
type of gun
# of entrance/exit wounds
high/low velocity
1st question to ask in any traumatic injury? - ANSWER - what was the dose of
energy involved?
(was it high or low?)
what is the caliber of a bullet? - ANSWER - diameter
aka diameter of a bullet - ANSWER - caliber
,what happens to projectiles when they enter the body - ANSWER - projectiles
don't travel in a straight line
consider temporary cavity wound

temporary cavitation

removal
-if superficial, it may migrate the surface with time

(VP Cheney accidentally shot his friend while hunting in 2006. ICU and did great.
moved to an inpatient unit. had a silent MI bc a shot gun pellets migrated into a
canary artery causing an infract. so had a MI but fibrinolytic not the answer in this
case b/c it was a "projectile embolus"
aka brestbone - ANSWER - sternum
what attaches the ribs to the sternum - ANSWER - cartliage
what breaks thoracic bones - ANSWER - significant force
-1-2nd ribs, posterior ribs, sternum, scapulae, T2-10
gives us info about the force aka "dose" of energy received
consider injury to internal structures b/c force
,ribs that are the most frequently broken - ANSWER - ribs 4-9 b/c long, thin, and
poorly protecte
it is harder to break a short pencil (T1-2) and easier to break a longer one
*ask how many and where to understand the force involved
what is the significance of posterior rib fractures - ANSWER - unusual direction of
injury
shorter stubby ribs
good muscle profection
**posterior rib fractures have a lot of force so need a high dose.
***PRF need a lot of force so high dose of energy. big red flag for t-spine injury
indication of c-spine injury - ANSWER - to injure c-spine, you don't need a big
energy blow. all it takes is shaking around.
c spine versus t spine fractures - ANSWER - c-spine doesn't need a big energy
blow. just some shaking around
t-spine needs a great strong direct blow (not just a shock_
treatment for rib fractures - ANSWER - largely supportive nursing care like
pulmonary toilet
CXR and rib fractures - ANSWER - simple rib fractures are difficult to see on CXR
and can be commonly missed
, (1/2 of all rib fractures aren't identified at the POI CXR)
identify a previous rib fracture on CXR - ANSWER - once healed, rib fractures form
bony callouses and become more visible on CXR
how to tell a pt has a pneumonia from a CXR - ANSWER - dark spot that is not
equal to the opposite side
consider if a pt has a lower rib fracture - ANSWER - liver & spleen injury
acts like BBQ/marshmellow skewers
how high does the diaphragm rise on inspiration - ANSWER - level of 4th ICS
risk of rib fractures - ANSWER - can puncture liver, spleen,, diaphragm
pop lungs
+2 adjacent rib fractures - ANSWER - flail chest
free floating sternum - ANSWER - flail chest
definition of flail chest - ANSWER - +2 adjacent rib fracture
free floating sternum
why is flail chest a problem - ANSWER - b/c breathing is a mechanical process
