Trauma

Initial Assessment and
Management of the Trauma
Patient

Mechanisms of Injury
 Blunt Trauma
• Compression Forces
 Cells in tissues are compressed and crushed
 E.g. Spleen
• Shear Forces
 Acceleration/Deceleration Injury
 E.g. Aorta
• Shearing force = Spectrum from Full thickness tear
(Exsanguination) to Partial tear (Pseudoaneurysm)
• Overpressure
 Body cavity compressed at a rate faster than the tissue
around it, resulting in rupture of the closed space
 E.g. Plastic bag
 E.g. in trauma = diaphragmatic rupture, bladder injury

Primary Survey
 Key Principles
• When you find a problem during the
primary survey, FIX IT.
• If the patient gets worse, restart from the
beginning of the primary survey
• Some critical patients in the Emergency
Department may not progress beyond the
primary survey

Initial management (resuscitation) must be prioritised according to the
physiological needs for survival. In the ‘A,B,C,D,E’ of resuscitation, the ‘A’
comes before the ‘B’, the ‘B’ before ‘C’ and so on. A problem identified at
any step must be corrected immediately before moving to the next step.
Please note that there is an exception to this rule
A A patent Airway
B Effective Breathing / Ventilation
C Adequate Circulation and haemorrhage control
D Neurological Disability
E Adequate Exposure to search for other injuries
Take home message!
Making a definitive diagnosis is the least important issue at this stage
During the primary survey life threatening conditions are identified and
management is instituted SIMULTANEOUSLY.

Airway and Protection of Spinal Cord
 Why first in the algorithm?
• Loss of airway can result in death in < 3 minutes
• Prolonged hypoxia = Inadequate perfusion, End-organ damage
 Airway Assessment
• Vital Signs = RR, O2 sat
• Mental Status = Agitation, Somnolent, Coma
• Airway Patency = Secretions, Stridor, Obstruction
• Traumatic Injury above the clavicles
• Ventilation Status = Accessory muscle use, Retractions,
Wheezing
 Clinical Pearls
• Patients who are speaking normally generally do not have a
need for immediate airway management
• Hoarse or weak voice may indicate a subtle tracheal or
laryngeal injury
• Noisy Respirations frequently indicates an obstructed
respiratory pattern

Airway Interventions
 Maintenance of Airway Patency
• Suction of Secretions
• Chin Lift/Jaw thrust
• Nasopharyngeal Airway
• Definitive Airway
 Airway Support
• Oxygen
• NRBM (100%)
• Bag Valve Mask
• Definitive Airway
 Definitive Airway
• Endotracheal Intubation
 In-line cervical stabilization
• Surgical Crichothyroidotomy

Protection of Spinal Cord
 General Principle: Protect the entire spinal cord until injury has
been excluded by radiography or clinical physical exam in
patients with potential spinal cord injury.
 Spinal Protection
• Rigid Cervical Spinal Collar = Cervical Spine
• Long rigid spinal board or immobilization on flat surface such as
stretcher = T/L Spine
 Clinical Pearls
• Treatment (Immobilization) before diagnosis
• Return head to neutral position
• Do not apply traction
• Diagnosis of spinal cord injury should not precede resuscitation
• Motor vehicle crashes and falls are most commonly associated with
spinal cord injuries
• Main focus = Prevention of further injury

C-spine Immobilization
 Return head to neutral position
 Maintain in-line stabilization (MILS)
 Correct size collar application
 Blocks/tape
 Sandbags

Breathing and Ventilation
 General Principle: Adequate gas exchange is required to
maximize patient oxygenation and carbon dioxide elimination
 Breathing/Ventilation Assessment:
• Exposure of chest
• General Inspection
 Tracheal Deviation
 Accessory Muscle Use
 Retractions
 Absence of spontaneous breathing
 Paradoxical chest wall movement
• Auscultation to assess for gas exchange
 Equal Bilaterally
 Diminished or Absent breath sounds
• Palpation
 Deviated Trachea
 Broken ribs
 Injuries to chest wall

Collaborative
• Observe the respiratory rate and effort of the patient. Assess the use
of accessory respiratory muscles.
• Palpate the neck carefully for tracheal deviation.
• Identify emphysema (air in the subcutaneous tissue) by palpating
the chest wall for crepitation (a crackling feeling)
• Place your hands in the patient’s axillae and gently compress the
chest. Tenderness and emphysema suggest chest trauma.
• Auscultate the lung fields in the axillae and compare both sides. No
air entry to both sides occurs in:
– an inadequately patent upper airway
– massive tension pneumothorax
– tracheal laceration
Take home message!
The respiratory rate and effort are sensitive indicators of chest trauma.
They should be monitored and recorded at frequent intervals.

 Identify Life Threatening Injuries
• Tension Pneumothorax
 Air trapping in the pleural space between
the lung and chest wall
 Sufficient pressure builds up and pressure
to compress the lungs and shift the
mediastinum
 Physical exam
• Absent breath sounds
• Air hunger
• Distended neck veins
• Tracheal shift
 Treatment
• Needle Decompression
 2nd
Intercostal space, Midclavicular line
• Tube Thoracostomy
 5th
Intercostal space, Anterior axillary line

Collaborative

 Hemothorax
• Blood collecting in the pleural space and is
common after penetrating and blunt chest trauma
• Source of bleeding = Lung, Chest wall (intercostal
arteries), heart, great vessels (Aorta), Diaphragm
• Physical Exam
 Absent or diminished breath sounds
 Dullness to percussion over chest
 Hemodynamic instability
• Treatment = Large Caliber Tube Thoracostomy
 10-20% of cases will require Thoracotomy for control of bleeding
http://www.trauma.org/index.php/main/images/C11/

 Flail Chest
• Direct injury to the chest resulting in an
unstable segment of the chest wall that
moves separately from remainder of thoracic
cage
• Typically results from two or more fractures
on 2 or more ribs
• Typically Accompanied by a pulmonary
contusion
• Physical Exam = Paradoxical movement of
chest segment
• Treatment = Improve Abnormalities in gas
exchange
 Early Intubation for patients with respiratory
distress
 Avoidance of overaggressive fluid resuscitation

 Open Pneumothorax
• Sucking Chest Wound
• Large defect of chest wall
 Leads to rapid equilibration of
atmospheric and intrathoracic
pressure
 Impairs oxygenation and ventilation
• Initial Treatment
 Three Sided occlusive dressing
 Provides a flutter valve effect
 Chest tube placement remote to site
of wound
 Avoid complete dressing, will create
a tension pneumothorax

Circulation
 Shock
• Impaired tissue perfusion
• Tissue oxygenation is inadequate to meet metabolic demand
• Prolonged shock state leads to multiorgan system failure and
cell death
 Clinical Signs of Shock
• Altered mental status
• Tachycardia (HR > 100) = Most common sign
• Arterial Hypotension (SBP < 120)
 Femoral Pulse – SBP > 80
 Radial Pulse – SBP > 90
 Carotid Pulse – SBP > 60
• Inadequate Tissue Perfusion
 Pale skin color
 Cool clammy skin
 Delayed cap refill (> 3 seconds)
 Altered LOC
 Decreased Urine Output (UOP < 0.5 mL/kg/hr)

Circulation
 Types of Shock in Trauma
• Hemorrhagic
 Assume hemorrhagic shock in all trauma patients until
proven otherwise
 Results from Internal or External Bleeding
• Obstructive
 Cardiac Tamponade
 Tension Pneumothorax
• Neurogenic
 Spinal Cord injury
 Sources of Bleeding
• Chest
• Abdomen
• Pelvis
• Bilateral Femur Fractures

Circulation
 Emergency Nursing Treatment

 Apply direct pressure
 Temporarily close scalp lacerations
• Close open-book pelvic fractures
 Abdominal pelvic binder/bedsheet
• Restore circulating volume
 Crystalloid Resuscitation (2L)
 Administer Blood Products
• Immobilize fractures
 Responders vs. Nonresponders
• Transient Response to volume resuscitation = sign of ongoing blood
loss
• Nonresponders = Consider other source for shock state or operating
room for control of massive hemorrhage

Circulation
 Pericardial Tamponade
• Pericardium or sac around heart fills with
blood due to penetrating or blunt injury to
chest
• Beck’s Triad
 Distended jugular veins
 Hypotension
 Muffled Heart Sounds
• Treatment
 Rapid evacuation of pericardial space
 Performed through a Pericardiocentesis
(temporizing measure)
 Open Thoracotomy

 A word about cardiac arrest . . .
• Care of the trauma patient in cardiac
arrest
 CPR
 Bilateral Tube Thoracostomy
 Pericardiocentesis
 Volume Resuscitation
• Traumatic Cardiac Arrest due to blunt
injury has very low survival rate (< 1%)
 No point for emergency thoracotomy
• Selected cases of cardiac arrest due to
penetrating traumatic injury may benefit
from emergent thoracotomy
 Pericardial tamponade
 Cross clamp Aorta

Disability
 Key Principles
• Precise diagnosis is not necessary at this point
in evaluation
• Prevention of further injury and identification of
neurologic injury is the goal
• Decreased level of consciousness = Head
injury until proven otherwise
• Maintenance of adequate cerebral perfusion is
key to prevention of further brain injury
 Adequate oxygenation
 Avoid hypotension
• Involve neurosurgeon early for clear intracranial
lesions

Disability
 Cervical Spinal Clearance
• Patients must be alert and oriented to person,
place and time
• Not clinically intoxicated with alcohol or drugs
• Non-tender at all spinous processes
• No focal neurological deficits
• No distracting injuries
• Painless range of motion of neck

Exposure
 Remove all clothing- assuming that other injuries are present
• Examine for other signs of injury
• Injuries cannot be diagnosed until seen by provider
 Logroll the patient to examine patient’s back
• Maintain cervical spinal immobilization
• Palpate along thoracic and lumbar spine
• Minimum of 3 people, often more providers required
 Avoid hypothermia
• Apply warm blankets after removing clothes
• Hypothermia = Coagulopathy(Hypothermia may be a cause of
coagulopathy)
 Increases risk of hemorrhage
 Do not forget to do a rectal examination whilst log rolling the

Secondary Survey
 Once the immediate life-threatening conditions have
been managed or excluded, the patient should be
completely re-examined
 If the patient deteriorates at any stage, the airway,
breathing and circulatory systems must be re-
examined as discussed previously for the primary
survey
 The secondary survey is a
head-to-toe, front-to-back assessment along with a
detailed medical history/AMPLE HX and
appropriate investigations

History
 AMPLE History
• Allergies
• Medications
• Past Medical/surgical History, Pregnancy
• Last Meal (time)

• Additional films
 Cat scan imaging
 Angiography
 Foley Catheter
• Blood at urethral meatus = No Foley catheter

Trauma in Special Populations
 Pregnancy
• Supine Hypotensive Syndrome
 After 20 weeks, enlarged uterus with fetus and
amniotic fluid compresses inferior vena cava
 Decreases venous return and decrease cardiac
output
 Keep pregnant patients in left lateral decubitus
position to avoid excessive hypotension
• Optimal maternal and fetal outcome is
determined by adequate resuscitation of
mother
• Fetal Monitoring

Trauma in Special Populations
 Pediatric Trauma Resuscitation
• Differences in head to body ratio
and relative size and location of
anatomic features make children
more susceptible to head injury,
abdominal injury
• Underdeveloped anatomy leads to
chest pliability and less protection
of thoracic cage
• Cardiac Arrest
 Typically result from respiratory arrest
degrading into cardiac arrest
• Resuscitation
 Broselow Tape
