Trauma
”
- expression comprising a
spectrum of severity of
mechanical violation of
tissues, from a little scratch
to a multiply injured patient.
- also surgical intervention.
seconds to minutes
minutes to hours
GOLDEN HOUR
several days or weeks
Trauma - the leading cause of death in the first four decades of life
Death from trauma has a trimodal
distribution:
within
•Prehospital – control airway, external hemorrhage,
rapid
transport
•Primary survey - initial assesement and
resuscitation of vital
functions, prioritization
(based on ABC
DEFG)
An organized consistent approach to
the trauma patient optimal
outcome.
The Advanced Trauma Life Support
(ATLS) adopted by the American
College of Surgeons in 1979.
The primary focus of ATLS is on the
first hour of trauma management -
rapid assessment and resuscitation
THE GOLDEN HOUR
The primary survey –
life threatening conditions are
identified and management is
begun simultaneously!
• A - Airway maintenance with cervical spine
control
• B - Breathing and ventilation
• C - Circulation with hemorrhage control
• D - Disability: neurological status
• E - Exposure: completely undress the
patient
Airway / Breathing
All patients should be
transported/treated initially
with supplemental oxygen.
• immobilization of
the C-spine
• combination of a
hard collar and
sandbags on
opposite sides of
the head
Airway / Breathing
• establishing verbal contact with the
patient - clear phonation by the patient
establishes that the airway is patent.
• further intervention depends on:
- neurologic stability
- adequacy of gas exchange and the
potential for airway compromise
Neurological Stability
• decreased level of consciousness is considered to
be intracranial pathology until proven otherwise
(drugs, alkohol)
• brief neuro exam (done during the primary survey):
A - Alert
V - responds to Verbal stimuli
P - responds to Painful stimuli
U - Unresponsive
• Glasgow Coma Scale (GCS):
GCS < 8 requires definite airway intervention to
prevent aspiration pneumonitis, to insure adequate
oxygen delivery and to avoid hypercarbia.
If a patient is responding only to painful stimuli or is
unresponsive/unconscious, the GCS is or has a high
likelihood of being less than 8.
Adequacy of Gas Exchange
• airway patency does not insure
adequate ventilation
LOOK
• nature of the injury: maxillofacial
trauma/airway burns - potential for
airway compromise, obvious airway or
chest trauma (sucking chest wounds,
flail segments), cyanosis
• tachypnea, use of accessory muscles of
respiration or evidence of tracheal shift
Adequacy of Gas Exchange
LISTEN
• stridor upper airway compromise.
• hyperresonance to percussion/lack of
air entry pneumothorax
• dullness to percussion/lack of air
entry hemothorax.
• bowel sounds in the chest
ruptured diaphragm.
Adequacy of Gas Exchange
FEEL
• hand over the mouth - feel for air exchange.
• Insertion of a finger - sweep to clear the mouth of
any foreign bodies (especially dislodged teeth) and
to evaluate for evidence of maxillofacial trauma.
LAB
• pulse oximetry - haemoglobin saturation;
immediate feedback
pitfalls - motion, peripheral vasoconstriction,
carboxy/methaemoglobinemia.
• ABG`s - more complete picture of the patient;
feedback on oxygenation, ventilation and tissue
perfusion
pitfalls - a defined waiting period (institution
dependent)..
Securing the Airway
-
endotracheal intubation
(inspection of th airway,
suction of blood and secretions, bag mask
ventillation)
- possible spinal cord or direct traumatic tracheal
injuries surgical airway -
translaryngeal
intubation
• Immediate - apnea
• Emergent - hypoventilation, significant
head injury, cyanosis
• Urgent - burns, maxillofacial injury and
cervical hematomas will likely require a
secure airway to prevent upper airway
obstruction; chest wall and pulmonary
injuries are usually initially well
compensated but may eventually require
mechanical ventilation
there is often time for a history, appropriate
physical exam and cervical radiographs
Securing the Airway
Blind nasotracheal intubation vs direct
orotracheal intubation
Determined by the experience of the physician
Blind nasotracheal intubation:
requires a spontaneously breathing
unconscious or cooperative conscious
patient, unacceptable failure rate (35%) -
requires 3.7 vs. 1.3 oral attempts,
contraindicated if basal skull or mid-face
fracture.
can precipitate epistaxis (may interfere with
subsequent alternative attempts at
intubation if unsuccessful).
high incidence of sinusitis if a tube is left in
place greater than 72 hours.
Assume the cervical spine to
be unstable until proven
otherwise
• up to 50% of patients sustaining C-
spine trauma develop neurologic
abnormalities (nerve root compression
and weakness to quadri- plegia and
death).
• 10% of patients with C-spine injury are
initially neurologically intact, but
develop deficits during the course of
emergency care
• risks of airway management
C-spine evaluation
• bone and soft tissue
• X-ray exam: „one view is no view”, L-all
7C+Th1 (30% inj.C7Th1), AP-vertical
alignment of the spinous and articular process
and abnormalities in joint and disc spaces,
open mouth view - integrity of the atlanto-
occipital and atlanto-axial joints, the odontoid
process, oblique – intervert. foramina
• CT
• lateral cervical spine - sensitivity of about 85%
92% in a three view series
100% when selective CT scanning is employed
Circulation
• BP
• HR
Alghevar scheme - quantification of shock:
SBP / HR
>1 no or minor clinical symptoms
<1 major shock
• Pulses
• Indirect signs: UA, skin, tachypnoe, altered
consciousness, „empty” periferal veins
Large bore IV lines
Circulation
• warmed intravenous infusions
Control:
• external hemorrhage
• internal hemorrhage:
MAST (PASG) suit
Pelvic binders
Surgery stabilisation secondary survey
Initial assessement
• Chest and abd. PE
• Orthopaedic PE
• Periferial Neurologic PE
• Labs
• X-rays, US, CT
tertiary trauma survey
• ACS definition - a patient evaluation that identifies
and catalogues all injuries after the initial
resuscitation and operative intervention
• 2 - 50% of combined life threatening and non-life
threatening injuries are missed during primary and
secondary surveys
• timing is institution specific (typically occurs within
24 h after admission and is repeated when the
patient is awake, responsive, and able to
communicate any complaints).
• is a comprehensive review of the medical record
with emphasis on the mechanism of injury and
pertinent co-morbid factors such as age, includes
the repetition of the primary and secondary
surveys, a review of all laboratory data, and a
review of radiographic studies with an attending
radiologist
