Introduction
Trauma leading cause death 1-40yo
Peak age 15-30
Cost in A$ 11 billion
Up to 40% trauma deaths preventable
Improvements largely due to social education Seat belts
Speed limits
Drink driving
Helmets
For each death estimated to be 10 serious non-fatal injuries
Essence of Trauma Care
Right patient to the right resources as soon
as possible
Achieved by:
Integrated system - ‘Trauma Network’
Seniority or experience of providers
Decision Pathways and education
Trauma Network
Ministerial Taskforce on Trauma and
Emergency Services - 1997
ROTES report (Trauma deficiencies) – 1999
Victoria State Trauma Network – 2000 Two adult and one paediatric hospital as major trauma services (MTS)
Statewide system organisation and management of trauma response
Trauma triage and transfer protocols
Enhanced retrieval and transfer services (ARV)
Education and training
Research, service and technology developments
Quality management.
http://www.ambulance.vic.gov.au/
Results
80 per cent of all major trauma patients are
treated at a MTS
a reduction in mortality rates with fewer than
expected deaths according to international
benchmarks
positive trends in preventable deaths
reduced length of stay in hospitals.
Introduction
Medical management has shown far less improvement
Standardisation of approach has helped improve outcomes
Concept of “Golden Hour”
50% deaths <1/24 due to major vessel, CNS, spinal injury
benefit from prevention
30% deaths patients major truncal injuries causing respiratory &
circulatory compromise
benefit from prevention and timely intervention
20% die from sepsis, organ failure etc.
benefit from prevention, timely intervention and possibly from integrated
approach to recovery
Prehospital
Very little evidence to support major interventions in
the field
Oxygenation
Immobilisation cervical spine
Ventilation (unproven)
Fluids (unproven)
Lights and sirens (increases mortality and
community risk)
Triage to trauma centre
http://docs.health.vic.gov.au/
Triage to trauma centre
Associations with increased risk of death
Demographics

RR <12 or >24
GCS < 13
O2 sats <90%
Trauma score >14 (not assessable prospectively)
Triage to trauma centre

neck or groin
Significant injuries to two or more body
regions
Severe injury to head, neck or trunk
Two or more proximal long bone fractures or
pelvis
Limb amputations (incl. partial or compound)

Triage to trauma centre
Mechanism
High speed >60 kph (>30kmh cyclists)*
Fall > 3m*
Struck on head by falling object >3m*
Ejection from vehicle*
Explosion*
Prolonged extrication
Pedestrian vs vehicle
And
>55 y.o. OR
Pregnant OR
Significant co-morbidity
Trauma teams
Team leader Overview
Resus
Assessment Communication
Internal & external
Airway team
Assess and secure airway
Control cervical spine
Ventilation
NGT
Procedure team
IV access & bloods
IDC
ICC
Scribe
Scout
Radiographers
• Assessment
• primary
• secondary surveys
Handover
Patient should transferred to trauma trolley prior to hand over
Parallel processing Team listens in ‘silent’ handover OR if pt unstable
Airway and procedure teams commence assessment
And
leader receives handover
Assume the worst & protect against unforeseen injuries do not focus on obvious injuries – protocol of ATLS
Primary survey
Airway & cervical spine
Assess & secure airway
Patency
Look, listen, feel
Jaw trust (no chin lift as cervical spine uncleared)
Oropharyngeal airway, nasopharyngeal airway?
RSI
Maintain cervical protection until spine cleared
In-line immobilization
Consider NGT
Primary survey
Ventilation/Breathing
Oxygen is the most important drug in the trauma room
Ensure adequate ventilation
Assess adequacy
Exclude pneumothorax, haemothorax
Bag/mask, ETT if required to maintain ventilation
Aim for normocarbia
CXR
Intervention may precede investigation if required
Primary survey
Circulation
Assess adequacy & effect of blood loss
Conscious state
Pallor
Capillary return
BP
HR
visual estimation of blood loss unreliable
FAST scan – ‘rule in’ test
Primary survey
Circulation
Control haemorrhage
pressure dressings
Tourniquets
Haemostatic dressings
Splinting
Thoracotomy (Cardiac manoeuvres/Aortic compression)
Theatre
Primary survey
Haemorrhage classification
Class Loss BP HR RR CR UFR CS
Class I <15% N N/+ N N/+ N N
Class 2 <30% N + + + anx
Class 3 <40% ++ ++ ++ leth
Class 4 >40% +/- +/- ++
coma
Primary survey
Circulation Access 2x >16G peripheral IV’s
Fluids initially crystalloid 20mlkg (repeat if required) warmed
Crystalloid vs colloid (no proven benefit)
Blood O negative Class III/IV haemorrhage
Continuing need for crystalloid
Consider need for clotting factors and plateletes ‘1:1:1’
Hypotensive resuscitation
Primary survey
Disability
Level of consciousness
AVPU
ALERT
VOICE
PAIN
UNCONSCIOUS
GCS – E4M6V5
Pupil response
Don’t ever forget the glucose
Primary survey
Monitoring
ECG, BP, SaO2, GCS +/- ventilator obs
Analgesia
Radiology
CXR, Cx spine, AP pelvis
IDC traditionally part of 1° survey but usually
done later
Secondary survey
Head to toe examination – ‘all over and all
holes’
Look, feel, move, listen
Log roll
PR examination
Consider
Tetanus toxoid
Antibiotic prophylaxis
Review
Constantly reassess and review
Any change repeat 1° survey
After any corrective procedure repeat 1°
survey
Disposition
Parallel thinking from before patients arrival
Direct to appropriate services
Definitive care made aware of patient
Discharge with appropriate support
Summary
You are all part of a trauma network
Education saves lives
Reassess, reassess, and reassess again
(and intervene if required of course . . .)
