By 2020 Trauma (physical injury) will be No. 3 on the WHO list - Global Burdens of Disease

• 1.25 million died globally from road trauma alone in 2013

7% increase in Indian road deaths in 2016

Decade of Action for Road Safety 2011-2020

27 June 2017

Goal - to stabilize and reduce the forecast level of

road traffic deaths around the world.

• Pre-hospital care systems development

• Hospital trauma care systems development

• Early rehabilitation and support to injured patients

• Establishment of appropriate road user insurance schemes

• Encourage research and development

#VicTGR

Haemorrhage is responsible for over

35% of pre-hospital trauma deaths

and over 40% of trauma deaths

within the first 24 hours.

Worldwide approximately 16,500 people die each day

from injuries, including 6,000 who bleed to death.

#VicTGR

Objectives

Demonstrate concepts of primary and secondary patient assessment

Establish management priorities in trauma situations

Initiate primary and secondary management as necessary

Arrange appropriate disposition

#VicTGR

Why Trauma team training

Trimodal death distribution

• First peak instantly (brain, heart, large vessel injury)

• Second peak minutes to hours

• Third peak days to weeks (sepsis, MSOF)

#VicTGR

Concepts of ATLS

Treat the greatest threat to life first

The lack of a definitive diagnosis should never impede the application of an

indicated treatment

A detailed history is not essential to begin the evaluation

“ABCDE” approach

#VicTGR

Initial Assessment and Management

An effective trauma system needs the teamwork of paramedics, emergency

medicine, trauma surgery, and surgery subspecialists

Trauma roles

Interventionalists

Nurses

#VicTGR

Trauma Team

#VicTGR

Primary Survey

Patients are assessed and treatment priorities established based on their injuries, vital signs, and injury mechanisms ABCDEs of trauma care A Airway and c-spine protection

B Breathing and ventilation

C Circulation with hemorrhage control

D Disability/Neurologic status

E Exposure/Environmental control

#VicTGR

Airway

How do we evaluate the

airway?

#VicTGR

A- Airway

Airway should be assessed for patency Is the patient able to communicate verbally?

Inspect for any foreign bodies

Examine for stridor, hoarseness, gurgling, pooled secretions or blood

Assume c-spine injury in patients with multisystem trauma C-spine clearance is both clinical and radiographic

C-collar should remain in place until patient can cooperate with clinical exam

#VicTGR

Airway Interventions

Supplemental oxygen

Suction

Chin lift/jaw thrust

Oral/nasal airways

Definitive airways

RSI for agitated patients with c-spine immobilization

ETT for comatose patients (GCS<8)

#VicTGR

Difficult Airway

#VicTGR

Breathing

What can we look for clinically to assess a patient’s ‘breathing’ status?

#VicTGR

B- Breathing

Airway patency alone does not ensure adequate ventilation

Inspect, palpate, and auscultate

Deviated trachea, crepitus, flail chest, sucking chest wound, absence of breath sounds

CXR to evaluate lung fields

#VicTGR

Flail Chest

#VicTGR

Subcutaneous Emphysema

#VicTGR

Breathing Interventions

Ventilate with 100% oxygen

Pleural decompression if tension pneumothorax suspected

Chest tubes for pneumothorax / hemothorax

Occlusive dressing to sucking chest wound

If intubated, evaluate ETT position

#VicTGR

Chest Tube for GSW

#VicTGR

What would we do for this patient who is having difficulty breathing?

#VicTGR

C- Circulation

Hemorrhagic shock should be assumed in any hypotensive trauma patient

Rapid assessment of hemodynamic status

Level of consciousness

Skin color

Pulses in four extremities

Blood pressure and pulse pressure

#VicTGR

Circulation Interventions

Cardiac monitor Apply pressure to sites of external hemorrhage Establish IV access 2 large bore IVs

Central lines if indicated

Cardiac tamponade decompression if indicated Volume resuscitation Have blood ready if needed

Level One infusers available

Foley catheter to monitor resuscitation

#VicTGR

D- Disability

Abbreviated neurological exam

Level of consciousness

Pupil size and reactivity

Motor function

GCS

• Utilized to determine severity of injury

• Guide for urgency of head CT and ICP monitoring

#VicTGR

Disability Interventions

Spinal cord injury

Early diagnosis/treatment /decompression stabilisation

ICP monitor- Neurosurgical consultation

Elevated ICP

Head of bed elevated

Mannitol

Hyperventilation

Emergent decompression

#VicTGR

E- Exposure

Complete disrobing of patient

Logroll to inspect back

Warm blankets/external warming device to prevent hypothermia

#VicTGR

Always Inspect the Back

#VicTGR

Diagnostic Aids

Standard trauma bloods

FBE/UEC/LFT/Coags/Lipase/Crossmatch, EtOH, ABG

Standard trauma radiographs

CXR, pelvis, lateral C-spine (traditionally)

CT/FAST scans

Pt must be monitored in radiology

Pt should only go to radiology if stable

Chest decompression

• There is no evidence that needle thoracostomy is a

reliably useful procedure for in-hospital trauma

resuscitation.

• ~1/3 of pleural cavities not reached

• Sub-Q gas under tension causes false positives

• Anatomical landmarks poorly determined1

Pitfalls of needle thoracocentesis

Extrapleural placement of

catheter-over-needle

thoracocentesis.

The catheter length is

adequate but is extra-pleural.

There is no pneumothorax.

#VicTGR

Pitfalls of needle thoracocentesis

False positive as chest tube decompresses subcutaneous emphysema There is a left pneumothorax. The tube thoracostomy has been placed extrapleural in sub-cutaneous gas - creating a false positive with associated failure to decompress the pleural space.

Pitfalls of needle thoracocentesis

Incorrect identification of the mid-clavicular line may result in needle decompression that is too medial, with increased risk of vascular and cardiac injury.

The recommended insertion point

(A) in the 2nd intercostal space in the midclavicular line is more lateral to the point commonly identified - which is half-way between the midline and the lateral chest wall (B).

pneumothorax or haemothorax and for ventilated

patients with pneumothorax.
