Major Trauma Management and Trauma Team Roles
Dr Christopher MoseleyCME Teaching 8th September 2016
Objectives
• Definition• State Trauma Network• Trauma Calls• Team Roles• Trauma mindset• Major Hemorrhage Protocol
Trauma Definition• A term derived from the Greek for “WOUND”
• It refers to bodily injury.
• It defined as tissue injury due to direct effects of externally applied energy. Energy may be mechanical, thermal, electrical, electromagnetic or nuclear.
• Includes: burns, drowning, smoke, inhalation and fall.
• Excludes: poisoning/toxic ingestion.
Trauma Definition
Major trauma — ‘multiple trauma’ — refers to major injury affecting more than one body system. It can also be defined as an Injury Severity score > 15.
Trauma in AustraliaTrauma accounts for: • 7.5% of total deaths
• 5.5% of hospitalisations
• 7% of the total burden of disease in Australia
* (Australian Institute of Health and Welfare, 2008).

PEOPLE
PLACE
EQUIPMENT AND DRUGS
People1) Clear roles and organization
2) Effective communication
3) Support from other hospital areas, transfer services and trauma centres

Trauma Definition• A term derived from the Greek for “WOUND”
• It refers to any bodily injury.
• It defined as tissue injury due to direct effects of externally applied energy. Energy may be mechanical, thermal, electrical, electromagnetic or nuclear.
• Included:burns, drowning, smoke, inhalation and fall.
• Excluded: poisoning/toxic ingestion.
Drugs and EquipmentConsider what may be required prior to arrival:• Difficult airway trolley• Blood including rapid transfuser• Drugs – e.g analgesia, TXA• IO kit• Procedure kits – chest tubes/thoracotomy kit

SpecialtiesSpecialties may include orthopedics, neurosurgery, cardiothoracics, plastics, ENT and ophthalmology.
Early notification of operating theatre staff and ICU is also crucial for critically ill trauma patients.
Radiography and radiology staff are a key part of trauma team activation.

HAEMOSTATIC RESUSITATION
In the bleeding trauma patient if it doesn’t carry oxygen or it doesn’t clot
then use with caution
1 in 4 trauma patients bleed abnormallyThe phenomenon of an early coagulopathy in trauma – which goes by many names, including the Acute Coagulopathy of Trauma-Shock (ACoTS) – can occur soon after injury, and is physiologically distinct from the DIC-like phenomenon associated with the “lethal triad”
Trauma patients bleed abnormally
Hypothermia Decreases platelet responsiveness, increases platelet sequestration in liver and spleen, reduces Factor function eg Factors XI and XII. Alters fibrinolysisAcidosis pH strongly effects activity of Factors V, VIIa and X. Acidosis inhibits thrombin generation. Cardiovascular effects of acidosis (pH <7.2) – decreased contractility and CO, vasodilatation and hypotension, bradycardia and increased dysrhythmias
Lethal Triad
Early hyperfibrinolysis
• Give blood products instead of isotonic crystalloid fluid aiming for limited volume replacement.
• Large volume crystalloids can lead to dilutional coagulopathy and exacerbate bleeding.
• Crystalloids have no O2 carrying capacity and do little to correct the anaerobic metabolism and O2 debt associated with shock.
• Oedema, compartment syndrome, resp distress
Blood Vs Crystalloid
Provides resuscitation with blood components resembling whole blood with the aims of:
• maintain circulating volume• limit ongoing bleeding• prevent the lethal trial of hypothermia, acidosis and
acute coagulopathy of traumaTypical triggers are:• expected or actual haemorrhagic shock• 4 PRBCs administered and instability persists
Haemostatic Resusitation
• Involves blood component ratios of 1 or 2 RBCs : 1 FFP : 1 platelets
• Rick Dutton freely admits that he made up the ratio of 1:1:1 based in the rationale that it mimics the composition of whole blood
• Australian National Guidelines advocates 2:1:1 ratio
HOW?
• There is no RCT evidence for RBC:FFP:platelet ratios of 1-2:1:1 versus other ratios/ fluids
• The PROPPR trial (2015) found no statistically significant mortality difference on the primary outcome of mortality between massive transfusion protocols based on 1:1:1 and 2:1:1 ratios. There was an absolute difference in mortality of about 4% favouring the 1:1:1 ratio
Evidence
• Other agents may be given based on blood tests:• INR >1.5 – FFP• Hb <100 in an actively bleeding -> PRBCs• Calcium <0.8 - calclium gluconate• Platelets <80 - platelets• platelet dysfunction (e.g. drugs) - platelets
Adjuncts
Tranexamic AcidTranexamic acid (TXA) is an anti-fibrinolytic agent that can/should be used early in the resuscitation of bleeding trauma patients
The effect of TXA on mortality in bleeding trauma patients is very time-dependent, conferring a huge survival advantage if given early
Tranexaminc AcidTranexamic acid (TXA) use is supported by the CRASH2 trial:
• a multicenter international RCT• Mortality benefit if given to major trauma patients
within 3 hours of injury.
Cryoprecipitate• Fibrinogen is the primary substrate for clot
formation (along with platelets)• There is a consistent link between falling fibrinogen
and mortality in trauma• The key is to measure and follow serum fibrinogen in
bleeding patients – a fibrinogen less than 1.0 g/L identifies a hypofibrinogenemic state, the antidote for which is cryoprecipitate.

…and stuff…
This Is the sum total of my knowledge on the subject so
questions to the boss!
