Trauma Flashcards
Influences on triage (5)
Number of injured
Available resources
Nature/extent of injuries
Change in condition
Hostile threat
Multiple Casualty
number of patients and severity do not exceed recourses
Mass Casualty
number of patients and severity exceed recourses
Principles of triage (5)
degree of life threat
Injury severity
Salvageability
Resources
Time/distance/environment
Injury severity entails
seeing the patient in a total global fashion
Triage categories
delayed
immediate
minimal
expectant
Immediate timeline
needs life saving within 1min-2H
Immediate examples
massive hemo
airway obstruction
tension pnuemo
retrobulbar hematoma****
Delayed examples
soft tissue injury
fracture
compartment syndrome
moderate burns
Minimal
self aid/buddy aid
aka walking wounded
What is essential to immediate life sustaining care
speed and accuracy
Secondary Triage
document, reassess, sort patients, 9-line
Tertiary Triage
manage patients, consider complicated procedures, resources
CPR only three situations
hypothermia, near drownings, electrocution
Early tauma deaths are to due to interuptions in what three systems
respiratory, vascular, central nervous
Trauma casualties typically die within
the first hour from inabilty to breath or bleeding
Light Combat Stress return to duty
immediate return to duty or units noncombat element
Heavy Combat Stress return to duty
combat stress control restoration for up to 3 days
Combat stress BICEP (SR)
Brief: 3 days or less
Immediate: treatment
Central: keep in one area
Expectant: expect to return to duty
Proximal: to unit
(Simple or refer)
3 phases of TCCC
CUF
TFC
TACEVAC
Soft tissue injuries are not lethal unless acompanied with
shock
Choose a CCP based on proximity to
PT
vehicular access
HLZ

Forms of energy
Mechanical
Thermal
Electrical
Chemical
Theodor Kocher
first proposed kinetic injury possessed by a bullet was dissipated in four ways
Four ways kinetic energy is dissapaited
Heat
Energy used to move tissue radically outward
Energy used to form a primary path by direct crush of the tissue
Energy expended in deforming the projectile
Temporary Cavity
momentary stretch or movement of tissue away
Permanent cavity
forms at time of impact and is caused by compression or tearing of tissue
Yaw
deviation of projectile in its longitudinal axis
Tumbling
forward rotation around center mass
Deformation
mushrooming of projecting that increases in diameter by a factor of 2
Low energy projectile
Knives or needles
throat, thoracic, abdominal, and back stabbing
Medium energy projectile
9mm
High energy projectile
.44 magnum
Indications for a laparotomy for blunt abdominal trauma
peritonitis
hemodynamic instability
Primary blast
effects of pressure form a blast wave; damages tympanic membranes in surviving casualties
Secondary blast
flying debris and fragments with blast wind; causes gross mutilation
Tertiary blast
body displacement
Quaternary blast
burns
CoTCCC TQs
CAT
SOFT-T
EMT (Emergency and Military TQ)
Most common cause of death on battlefield; when to use permissive hypotension
hemorrhage; internal bleeding
CoTCCC approved hemostatic agents
combat gauze (first choice)
celox/chito
XStat
Chito/Celox active ingredient
chotosan; mucoidal binding
XStat
first expanding wound dressing to be cleared by FDA
3 junctional TQs
CROC
JETT
SAM
Hemostatic dressings require how much direct pressure
3 minutes
Respiratory control center
medulla and pons
Hypoxia
deficient oxygen in tissue
Indications for oxygen therapy
Cardiac/Respiratory arrest

carbon monoxide poisoning
Most common cause of airway obstruction
