Geographic distribution
Morbidity and Mortality
Trauma is a disease that remains the
leading cause of death for all Americans
Regardless of gender, race or economic
status
 Leading Cause of death for ages 1-45yrs

› (see chart pg 234)

1-3 yrs= MVA
› Due to unrestrained/ or improperly restrained

15-24= Accidents related to Drugs and
Alcohol
› Due to poor judgment and risk-taking behavior
Age

16-19= MVA
› Due to inexperience, lack of seatbelt usage,
etoh with driving

75+= “injuries”
› Due to frailer health, pre-existing conditions,
Falls (most common cause in 65+ age group)
› Drivers 65+ have the highest death rate, per
mile driven (except for teenagers)
› More likely to sustain a C-Spine injury
Race
Gender

Males are 2.5 times more likely to be
injured than females
› Related to their participation in hazardous
activities, and greater risk taking

The Auto vs Ped, and MVA death rate is
2x higher across the life span compared
to women

African American- Homicide, MV (65+),
and auto/ped
White/Native American- Suicide
Hispanic- Pedestrian, Homicide


Fire Arms
 Alcohol
 Geography –Urban vs Rural
 Chronology- Weekends and Holidays

Beware of Adrenaline- pt may at first
appear uninjured
 MOI- What is the Mechanism Of Injury,
and does the injury match?
 Trauma Team Criteria?

Treatment of trauma patients depends
on identifying all injuries and rapidly
intervening to correct those that are “life
threating”
 Consideration of mechanisms of injury is
essential to identifying patients with
possible underlying injuries who require
further evaluation and treatment

Leading Cause of Death and permanent
disability- considered a MAJOR public
health problem
 2 million people every year

› 8x more than cancer, 34x more than HIV
50,000 deaths, 200,000 hospitalizations,
1million ER visits
 $60 billion in costs in 2000

› Average lifetime cost per survivor $111,578
› Average cost per fatality $454,717
Injuries can occur to the skull, brain, soft
tissues, vascular structures, and cranial
injuries
 Mechanism are varied

› Car crashes, sports, falls, penetrating wounds
› High risk behaviors include ETOH abuse,
drugs
Classified by:
 Mechanism
› Blunt or Penetrating

Severity
› Mild, Moderate or Severe

Type
› Fracture, focal brain injury, diffuse brain injury

GCS is 14-15
› Usually discharged after short observation
Normal pupils, may be asymptomatic,
intact orientation/memory
 Eg: Scalp Lacerations


GCS 9-13
› High potential for
increased ICP
Associated with
Structural
injury/damage
 May require more
frequent monitoring
 Eg: Contusion


GCS- 8 or less
› Associated with Severe structural damage
High mortality rate
 Usually have long term or permanent
cognitive and physical disabilities

› Aggressive initial management to ensure
adequate oxygenation and preventing HTN
is essential

A reaction to a change
in any one of the 3 fixed
brain volumes
› Brain, CSF, or blood
If not immediately
corrected will
compromise cerebral
blood flow
 Normal ICP is 0-15,
greater than
20=intracranial
hypertension

Early S/S ~ HA, N/V, ALOC, pupils sluggish
 Late S/S ~ Pupils fixed/dilated, arousable
only to deep stimuli (gcs <8), posturing,
temperature changes


bradycardia, irregular resp rate)

Treatment
›
›
›
›
›
›
›
Monitor ABC’s
Prepare for intubation (propofol)
Medicate with benzo’s
Mannitol?
Decrease stimulus
Consider insertion of ICP monitor
Decrease metabolic demands of the brain
 Maintain normal temperature
 Maintain normal glucose
 Prevent seizures (Dilantin)
Linnear skull
fracture
 Non-displaced,
most common
type, usually
benign


Depressed skull
fracture
› Damages underlying
brain tissue and
vessels by
compression or
laceration. May
precipitate seizures

Basilar skull fracture
› May occur in anterior, posterior or middle
fossa. Leads to infection, hematoma, CSF
leakage, SZ
› S/S ~ ALOC, pupil change, CSF leak, Battle
sign, Raccoon eyes, change in mentation
 Change in mentation or combative
behavior, is hallmark
› Avoid nasal intubation or NGT
Bruise on the surface of the brain
 Occurs from movement of the brain
within the skull
 Coup and Contrcoup
 S/S are ALOC, N/V, vision changes,
weakness, and speech deficit

Collection of blood between skull and dura
 Usually r/t laceration of the middle
meningeal artery assosciated with a
temporal or parietal skull fracture
 Mortality is 50%
 S/S ~ Initial period of unconsciousness, lucid
interval (5 min-6 hrs), rapid
unconsciousness, unilateral fixed or dilated
pupils, Cushing’s Triad
 TX: prepare for evacuation/OR

Collection of blood between dura mater
and subarachnoid layer
 Usually caused by trauma
 Usually venous, therefore a slower bleed
 S/S ~ HA, drowsiness, confusion, steady
decline in LOC, unilateral fixed and/or
dilated pupils
 TX: ABC’s, prep for OR (most successful if
done within 4hrs of injury)

Collection of blood between arachnoid
mater and the pia mater
 Caused by aneurysm rupture, AV
malformation.

› Aneurysm can be caused by valsalva, sexual
activity, heavy lifting, or excitement

Usually 40-60 y/o. 12% die before
reaching hospital, 30% that survive have
severe neurologic deficits

S/S ~

traction

When complete spinal cord injury
occurs, all motor and sensory function
below the level of injury is lost
› Immediate onset

S/S: Flaccid paralysis, a-reflexia,
bowel/bladder dysfunction, disruption
in thermoregulation
›
Neurogenic shock (above T6) s/s include
sypathetic NS causes Bradycardia and
Hpotension
• Results from
hyperextension
• Bowel and
bladder fx
intact
• Results from
disruption of the
anterior spinal artery
• Can feel vibration,
touch, and pressure
• Posterior cord
syndrome light
touch impaired
by not lost
 Results from Hemisection
of the cord
 Most common from
penetrating injury
 Ipsilateral (same side)
paresis or hemiplegia
and total loss of function
 Contralateral (opposite
side) has decreased
sensation to pain and
temperature changes
Complication of injury at or above T6
 Life Threating injury- occurs when
sympathetic stimulation leads to massive
uncontrolled cardiovascular response
 Common Causes: Full bowel or bladder
at the time of injury


