History of Battlefield Advanced Trauma
Life Support
Following
the attendance on one of the American courses by the late Brigadier Ian
Haywood, a former Professor of Military Surgery, the need was identified for a
similar course modified for military requirements. The Department of Military
Surgery at the Royal Army Medical College [now the Royal Defence Medical
College (RDMC)] and the Army Medical Services Training Group [now the Defence
Medical Services Training Centre (DMSTC)] were tasked with devising a course
for the British Army.
Although
the Battlefield Advanced Trauma Life Support (BATLS) Course is about training
doctors for war, there is nothing new in this. Medical officers in former times
had to deal with the injuries of the day - contusions, lacerations, penetrating
wounds and broken bones - and under the primitive conditions prevailing at the
time.
The Modern Era
Today’s
medical services still have to deal with similar wounds, but they also have to
contend with injuries produced by modern weapons - including not only gunshot
wounds, but more importantly,multiple injuries produced by fragments with relatively
high velocities and capable of

Fragments
and bullets
Bombs,
shells, grenades and other explosive devices, cause death and injury due to
victims being hit by primary and secondary fragments and due to the effects of blast.
In older weapons, primary fragments were derived from the weapon casing and, as
such, had wide variation in size, shape and weight. These weapons produced Random
fragmentation and producing high energy-transfer wounds. They also have the
problems of the effects of blast and the horrors of extensive burns.
Modern
fragmentation amunitions are designed to deliver many hundreds of preformed
fragments of different types. These fragments are much more uniform in size,
shape and weight. Examples include, the pre-notched wire in a hand grenade,
flechets in bomblets and etched plates in shells and mortar bombs. These
weapons are referred to as improved (pre-formed) fragmentation devices Improved
fragmentation devices are designed not to increase lethality but, to increase
the likelihood of a hit. In fact, the lethality has fallen. The concept of the
use of these weapons is a simple one: increase the likelihood of a hit, generate
more enemy casualties and choke his logistic evacuation chain. The same concept
also applies when these weapons are used by the enemy against friendly forces!

Early
rifle bullets depended on their mass and shape in order to produce injury, velocity
was less important. For modern rifle and machine gun bullets, mass has fallen considerably
but velocity risen dramatically. Given that the energy of a missile is derived from
the formula 1/2JMV2 [M = mass, V =
velocity],
this means the available energy in a modern military bullet has risen several
fold.
