Objectives
• Identify the correct sequence of priorities for
assessment of a multiple injury trauma
patient.
• Identify the principles outlined in the primary
and secondary evaluation surveys to the
assessment of a multiple injury patient.
• Identify guidelines and techniques in the
initial resuscitative and definitive-care phases
of treatment of a multiple injury patient.
Injury Statistics
• Leading cause of death for ages 1-44
• $ 500 billion dollar annual cost
• Estimated 20-50 million injuries occur per year
(40 % of emergency room visits)
• Leading causes of trauma are motor vehicle
crashes, falls, and assaults
Trimodal Death Distribution
• Death due to injury
occurs in one of
three periods or
peaks
• Care provided
during each of
these periods
impacts patient
outcomes
Trimodal Death Distribution
• First peak – occurs within seconds to minutes
of injury
• Second peak – occurs within minutes to
several hours following injury
• Third peak – occurs several days to weeks
after initial injury
Advanced Trauma Life Support (ATLS)
Assess the patient’s condition rapidly and
accurately
Resuscitate and stabilize the patient according
priority
Determine if patient’s needs exceed a facility’s
resources/or doctor’s capabilities
Arrange for transfer (what, where, when, who,
and how)
ATLS
• Assure that optimum care is provided and
level of care does not deteriorate at any point
during evaluation, resuscitation, or transfer
process
What is a Level One Trauma Center?
A hospital equipped to provide
comprehensive emergency medical services to
patients suffering traumatic injuries.

Which way for the Airway?
Rapid Sequence Intubation
• Be prepared to perform a surgical airway in
the event that airway control is lost
• Pre-oxygenate patient with 100% oxygen
• Administer analgesic / sedative (IV) if feasible
• Apply pressure over cricoid cartilage
– Debatable
• Administer a paralytic IV
• Perform chin lift/jaw thrust
Rapid Sequence Intubation
• After the patient relaxes, intubate
orotracheally
• Inflate cuff and confirm placement
– auscultate and determine CO2 in exhaled air
• Release cricoid pressure
• Ventilate
• CXR

Vital Signs
Primary Survey
Circulation with Hemorrhage Control
• Control hemorrhage
• Activate trauma (Massive Transfusion Protocol)
– 6U pRBC, 4U FFP, 1 Platelets
– MD activation only
• Judicious use of crystalloid
6 areas potential blood loss

Trauma
• Majority deaths occur in 1st few hours after
injury
• Hemorrhage largest % deaths within 1st hour
• Hemorrhagic shock and exsanguination
– 80% deaths in OR
– 50% deaths 1st 24 hrs after injury
• Very few hemorrhage deaths after 1st 24 hours
• Only CNS injury more lethal
Special Considerations In Diagnosis
and Treatment of Shock

Medications

Pacemakers
Vascular Access
• 2 large-caliber, peripheral IVs
• Central access
– femoral
– jugular
– subclavian
• Intraosseous
• Obtain blood for crossmatch
• Trauma panel – CBC, BMP, coags

Direct Effects of Hemorrhage
• Class I – (up to 15% blood volume loss)
Exemplified by the patient that has donated one
unit of blood
• Class II – (15% - 30% blood volume loss)
Uncomplicated hemorrhage for which crystalloid
fluid resuscitation is required
Direct Effects of Hemorrhage
• Class III – (30% - 40% blood volume loss)
Complicated hemorrhagic state in which at least
crystalloid infusion is required and perhaps also
blood replacement
• Class IV – (more than 40%)
Considered a pre-terminal event, and unless
very aggressive measures are taken, the patient
will die within minutes
Fluid Resuscitation
• Balance organ perfusion with risk of re-bleeding
– may reverse vasoconstriction of injured vessel
– Dislodge early clot
– Dilute coagulation factors
– Cool patient
– Induce visceral swelling
Too much fluid?
Adequacy of Resuscitation
Clinical Variables

Primary Survey - Disability
Neurologic Evaluation
• Baseline neurologic evaluation
• GCS scoring
• Pupillary response
**Observe for neurologic deterioration
Head Trauma
• Severe CHI (GCS < 9) vulnerable to secondary
brain injury
• Hypotension doubles mortality
• Hypoxia and hypotension increases mortality
by 75%
• Normovolemia goal (dehydration harmful)
• Hypertonic saline or Osmotic Agent (mannitol)
Head Trauma
• Hyperventilation used cautiously
– only used if patient rapidly deteriorates
• PCO2 no lower than 30-35
• Prolonged hyperventilation can produce
cerebral ischemia and secondary brain injury
• Mannitol useful
– after adequate volume resuscitation
Spinal Cord Injury
• Neurogenic Shock
– Consider hemorrhage first…
• Maintain spine immobilization
• Fluid or no fluid?
• Vasopressors
Septic Shock
• Uncommon immediately after injury
• May occur several hours after injury
(especially if transfer to emergent facility
delayed)
• May occur in penetrating abdominal injuries
– contamination of intestinal contents into
peritoneal cavity
Primary Survey Exposure/Environmental Control
• Completely undress the patient
• Prevent hypothermia
Deadly Triad
• Hypothermia
• Acidosis
• Coagulopathy
Hypothermia (HT)
•
•
•
•
Frequent in trauma/massive transfusions
Trauma-related HT considered poor prognostic sign
Mortality directly  to degree and duration
Inhibits coagulation factor synthesis, prolongs PT and
PTT
• Severely affects platelet count and function
• Attenuates vital CV compensatory responses,
predisposes to arrhythmias
Re-warming
• Aggressive therapy associated with significant
decrease in:
– blood loss
– fluid requirements
– organ failure
– LOS in ICU
– mortality rate
Secondary Survey
• Begins after ABCDE is completed
• Resuscitative efforts underway
• Each region of the body is completely
examined
Trauma imaging
• Chest x-ray
• Pelvis x-ray
• FAST
– focused assessment sonography in trauma
• DPL (center-dependent)
– diagnostic peritoneal lavage
• CT scan
– Traumagram
Adjuncts Secondary Survey
• Foley
• NGT
• ABG/lactate
– If actively resuscitating
Primary Goal of Initial Operation
for a Trauma Patient
Damage Control
• Hemorrhage Control
• Contamination
Why Trauma NPs??
High acuity, high volume with seasonal surges.
Transition area of 17 beds experiencing delayed throughput
Hypothesized that by adding experienced Trauma NPs, we could improve throughput
and quality in care.
1 year, compared with 2 years prior
Results:
• Increased volume of cases by 14.3%
• 1.0 reduction in ALOS for entire trauma service
• 27.8 million reduction in hospital charges.
• Increased direct discharges by 21%.
MD/RNs found the addition of ACNPs beneficial, improved patient care, improved
workflow, improved communication and throughput.
