ATLS principle-1



1.Patient life-threatening injured first in
group injurys, life-threatening priority
of multiple injury
2.Effective treatment not be delayed
without clear diagnosis
3.Comprehensive analysis of injuries is
in need, history in the first assessment,
diagnosis and treatment is not necessary.
ATLS principle-2


If the injured patients and the severity
do not exceed the processing power of
the medical staff, to give priority to
those critically ill, multiple trauma
patients.
If exceed, to give priority to those timeconsuming short, less manpower and
equipment needed to care for patients.

Emphasis on airway, breathing, and
circulation (ABCs)
Assessment of airway patency, adequacy of
ventilation (respiratory excursion and lung
auscultation), hemodynamic status (pulse
rate, central and peripheral pulse quality,
blood pressure), and evidence of controllable
hemorrhage should be immediately linked
with interventions.

Skills:Trauma airway
management


Expert management of the airway is an
essential skill for the emergency
physician (EP).
Trauma patients benefit from early
control of the airway to ensure
adequate oxygenation and ventilation
and to protect against aspiration.
Techniques of airway management



orotracheal intubation (OTI)
conjunction with rapid sequence
induction (RSI) is the preferred
approach to the airway management of
the majority of patients with traumatic
injuries.
blind nasotracheal intubation (NTI)
surgical cricothyrotomy
Oropharyngeal airway
orotracheal intubation (OTI)
blind orotracheal intubation
blind orotracheal intubation
ED management


1. Oxygen should be administered to all
major trauma patients, early control of the
airway may be lifesaving and should take
priority over all other interventions.
2.Gaining intraveneous access rapidly is
essential to begin volume replacement and
support the hemodynamics.
ED management



3. Fluid therapy, intravascular volume
replacement to compensate for blood loss and
restore tissue perfusion has been accepted
standard therapy for many years.
Optimal type of fluid:
crystalloid solutions such as normal saline
Lactated Ringer solution
Fluids may be warmed ahead of time or be
administered through a fluid warmer.
ED management



4. Red blood cell substitutes, with the
ability to carry oxygen
Typed and cross-matched PRBC are
the best choice for blood transfusion
If there is ongoing massive
hemorrhage, fresh frozen plasma (FFP)
and platelets may be needed to restore
the coagulation system.
ED management

5. Pneumothorax or hemothorax should
be managed by the placement of a
large chest tube (32 or 36 French) in
the lateral chest.
A
B
ED management

6. A pericardiocentesis needle is
inserted in the left subxiphoid area and
directed 45 degrees toward the left
shoulder or sternal notch in pericardial
tamponade patients.

Trauma scoring systems


Trauma scores are an imperfect but
commonly used tool in trauma systems. They
are used for planning purposes and as a
quality assurance screen to monitor system
performance.
Regional trauma planners use these scoring
systems to compare institutions and assess
resource needs and as a tool for performing
research on the effects of different
interventions.
Revised Trauma Score (RTS)


Three components: GCS, systolic blood
pressure, respiratory rate
RTS<12 identified 97.2% of all fatally
injured patients.
Anatomic Scores


Injury Severity Score (ISS) : an extension of
the Abbreviated Injury Scale(AIS)
AIS grade divide the body into six
regions( thorax, abdomen, visceral pelvis,
head and neck, face, bony pelvis and
extremities, external structures), and
utilizing the site with the worst injury from
each region when calculating the overall
score.
Anatomic Scores

ISS was devised by summing the
squares of the highest AIS grade in
each of the three most severely injured
areas. When ISS above 15, death from
trauma begins to rise significantly.
Additional-2:
occult abdominal injury
Evaluate the abdomen



1. Diagnostic peritoneal lavage (DPL)
Advantages:
high accurate(92~98%), has reliable
significance when negative, mandate a
laparotomy prior to transfer to a trauma
center
Limitations:
invasive, insensitve for retroperitoneal
injures, when CT and US are unavailable
DPL



A positive DPL in a hemodynamically
stable patient should not automatically
lead to laparotomy.
Up to 30% of grossly positive lavages
lead to nontherapeuric laparotomies.
Diagnostic peritoneal lavage can
improve the positive rate of peritoneal
puncture.
DPL
ultrasonography (US)


Advantages: noninvasive, can be performed
at the bedside, able to reliably find fluid
within the abdomen and within the pericardial
sac, accurate with significant intra-abdominal
hemorrhage, has good diagnostic accuracy
for long-bone fractures and hemothorax and
is more accurate than supine chest
radiography for detection of a pneumothorax
Limitations: can’t show the source or
magnitude of the injury,
CT


Advantages: offers both quantitative
and qualitative information, gold
standard for evaluation of the
abdomen in the hemodynamically
stable blunt trauma patient,
Limitation: decreased sensitivity for
bowel, mesenteric, pancreatic injury

Traumatic shock


Shock is the ultimate consequence of
inadequate tissue perfusion, which may
be manifested clinically by hemodynamic
disturbances or organ dysfunction.
Shock is a common and potentially
treatable cause of death in injured
patients.
Traumatic shock






Caused by:
Most related to loss of circulating blood
volume caused by hemorrhage
Inadequate oxygenation
Cardiac dysfunction
Neurologic dysfunction
Mechanical vascular obstruction
Types of shock





1. hemorrhagic or hypovolemic
loss of circulating intravascular volume
caused by blood loss internally,
externally, or both
2. cardiogenic
3. neurogenic or vasogenic
4. septic
complications

If the acute stress of the traumatic
shock state is sufficiently severe or
prolonged, organ dysfunction may also
develop, including acute tubular
necrosis (ATN), adult respiratory
distress syndrome (ARDS), and multiple
organ failure (MOF).
Clinical presentation


Initial findings: tachycardia, hypotension,
signs of poor peripheral perfusion, alteration
in mental status
Continued blood loss result in: BP decrease,
narrowed pulse pressure(pulse quality weak
or thready), cool, pale, clammy extremities,
alteration in mental status, decline in urine
output (caused by renal hypoperfusion and
renal fluid reabsorption)
