although military trauma may be a combination of the two .

,The intensity of the blast wave diminishes rapidly over distance . Those close
to the point of explosion may display what 4 injuries and their definitions?
Right Ans - Avulsive amputation - where the limb is ripped away by the blast
Perforated hollow viscus ( tympanic membrane ( TM ) , gut ) , which occurs
when air in the viscus is compressed then re - expands
Haemorrhage into the alveoli ( " blast lung " ) , which occurs as a result of
spalling at air- tissue interfaces ( hit the outside of a rusty bucket with a
hammer and watch the rust fly off the inside this is spalling .
Air embolism ( coronary artery and cerebral
The severity of injury caused by missiles ( fragments and bullets ) is multi -
factorial . Amongst the many factors that determine the severity of injury
caused by missiles are : Right Ans - Kinetic energy available to the missile
( mostly from Velocity ) .
Shape and stability of the missile
Density of the tissue
Length of the wound track
Cavitation and shock wave
Temporary cavitation effect ( High - velocity bullet fired from right to left )
The type of fragmentation devices, have different levels of lethality, what is
the level for random fragmentation devices? Right Ans - 1 in 5 (shell) 1 in
10 (grenade)
The type of fragmentation devices, have different levels of lethality, what is
the level for improved fragmentation devices? Right Ans - 1 in 7 (shell) 1 in

down caused by the blast , where the body is thrown to land against the
ground or other hard object , generates blunt trauma patterns similar to those
seen in civilian falls from height or Road Traffic Collisions
Tertiary blast injuries such as crush injuries are defined as? And can cause
what? Right Ans - Structural collapse may lead to crush injuries . Here the
damage results from time under pressure rather than a discrete single
impact . Initially this is treated as any other blunt trauma , but may have
serious complications later as swelling increases affecting blood supply ,
especially to limbs ( compartment syndrome ) and toxins released from the
damaged tissues can injure the kidneys .
Qauternary Blast injuries - type of burns seen? Right Ans - Burns following
an explosion are traditionally described as superficial flash burns confined to
exposed skin ( typically the face and hands ) .
Full thickness burns will also be seen in those close to the point of explosion .
Qauternary Blast injuries - toxic inhalation definifition, explanation and intial
management? Right Ans - Many explosions generate toxic gases as a by -
product . These may present later with variety of medical problems such as
breathlessness and reduced level of consciousness . However in the initial
stages , problems with breathing or conscious level should be assumed to be
the result of direct trauma and treated as such .

Right Ans - Fragmentation
What Injuries would you anticipate from the deformation of the vehicle ?
Right Ans - Head and Face
Abdomen
Cervical Spine
Pelvis
Chest
Lower Limbs
Falls from a height of ____ are consistently associated with severe injury.
Right Ans - 5 metres ( 15 feet are height)
