slide7. Energy and Trauma (2 of 2) Different forms of energy produce different kinds of trauma.
Mechanical energy
Kinetic energy
Potential energy
Chemical energy
Thermal energy
Barometric energy<br>
slide8. Mechanism of Injury Profiles Different types of MOIs produce many types of injuries.
Injuries sustained by trauma patients may be the result of multisystem trauma, falls from heights, motor vehicle and motorcycle crashes, vehicle versus pedestrian, gunshot wounds, and stabbings.
Maintain a high index of suspicion for serious unseen injuries.<br>
slide9. Blunt and Penetrating Trauma Blunt trauma
Injury primarily without anything penetrating the soft tissues or internal organs and cavities
Penetrating trauma
Injury by objects that pierce and penetrate the surface of the body<br>
slide10. Blunt Trauma (1 of 13) Results from an object making contact with the body
Two of the most common MOIs:
Motor vehicle crashes
Falls
Maintain a high index of suspicion during patient assessment for hidden injuries.<br>
slide11. Blunt Trauma (2 of 13) Motor vehicle crashes

slide17. Blunt Trauma (8 of 13) Rollover crashes
Most common life-threatening event is ejection or partial ejection of the passenger. © iStockphoto/Thinkstock/Getty.<br>
slide18. Blunt Trauma (9 of 13) Rotational crashes
Injuries are a combination of frontal and lateral impacts.
Three-point seat belts are effective in preventing injury.<br>
slide19. Blunt Trauma (10 of 13) Vehicle-versus-pedestrian crashes
Three phases of impact:
Vehicle-pedestrian impact
Pedestrian rotates onto the hood.
Pedestrian rolls off onto the ground.
Injury pattern depends on the height of the pedestrian and the body area facing the impact.
Multisystem trauma is common after this type of event.<br>

slide21. Blunt Trauma (12 of 13) Motorcycle crashes
Patients should undergo cervical spine assessment.
Types of motorcycle impacts
Head-on crash
Angular crash
Ejection

slide22. Blunt Trauma (13 of 13) Falls
Greater the height of the fall, greater the potential for injury
Internal injuries pose the gravest threat.
Take into account
Height of the fall
Type of surface struck
Part of the body that hit first
Area of the body over which the impact is distributed © Jones & Bartlett Learning.<br>
slide23. Penetrating Trauma (1 of 5) Can be classified as low energy, medium energy, or high energy
Low-energy penetrating trauma may be caused by impalement or a knife, ice pick, or other weapon. Courtesy of Andrew N. Pollak, MD, FAAOS.<br>
slide24. Penetrating Trauma (2 of 5) Point-blank and high-velocity gunshot wounds result in more significant injuries.
Body area involved can be estimated by looking at:
Entrance location
Length of weapon © E.M. Singletary, M.D. Used with permission.<br>
slide25. Penetrating Trauma (3 of 5) Determine the number of penetrating injuries, then combine that information with what you know about the potential pathway.
Gunshot wounds
Frangible bullets increase damage due to multiple fragments.
Hollow point bullets expand as they enter the target.
Full metal jacket bullets cause less damage than fragmented rounds.<br>
slide26. Penetrating Trauma (4 of 5) The bullet’s speed is a major factor in the resulting injury pattern.
Cavitation results from the rapid changes in tissue and fluid pressure. © Jones & Bartlett Learning.<br>
slide27. Penetrating Trauma (5 of 5) Relationship between distance and severity of injury varies depending on the type of weapon involved.
Air resistance slows the projectile, reducing tissue damage.
Exit wounds are often much larger than entrance wounds. © Charles Stewart MD, EMDM MPH.<br>
slide28. Blast Injuries (1 of 4) Most commonly associated with military conflict
Also seen in civilian practice in industrial settings
Primary blast injuries
Entirely due to the blast itself
Damage to the body caused by pressure wave
Proximity to the origin of the pressure wave is associated with a high risk of injury or death.<br>
slide29. Blast Injuries (2 of 4) © Jones & Bartlett Learning.<br>
slide30. Blast Injuries (3 of 4) Secondary blast injuries
Result from being struck by flying debris
May cause blunt and penetrating injuries
Tertiary blast injuries
Occur when a person is hurled by the force of the explosion against stationary, rigid objects
Injuries result from both blunt and penetrating mechanisms.<br>
slide31. Blast Injuries (4 of 4) Quaternary (miscellaneous) blast injuries
Result from the miscellaneous events that occur during an explosion
Quinary blast injuries
Caused by biologic, chemical, or radioactive contaminants added to a traditional explosive device<br>
slide32. Tissues at Risk Organs that contain air are most susceptible to barotrauma.
Tympanic membranes can help determine the possible presence of other blast injuries.
Pulmonary blast injuries results from short-range exposure to the detonation of explosives.
Pneumothorax is a common injury and may require emergency decompression.<br>
slide33. Multisystem Trauma (1 of 3) Injuries of a person who has been subjected to multiple traumatic injuries involving more than one body system
Provide rapid treatment and transportation, and alert medical control.
Patients have high morbidity and mortality.<br>
slide34. Multisystem Trauma (2 of 3) Golden principles of prehospital trauma care:
Ensure safety.
Determine the need for additional personnel or equipment.
Evaluate the MOI.
Identify and appropriately manage life threats.
Assess and manage the airway.<br>
slide35. Multisystem Trauma (3 of 3) Ensure that basic shock therapy is completed.
Rapidly proceed with spinal immobilization if indicated.
During transport, obtain a SAMPLE history.
For critically injured patients, consider paramedic intercept and/or air medical transportation.<br>
slide36. Patient Assessment (1 of 4) Identifying life-threatening illnesses and injuries as soon as possible improves patient outcomes.
Assess, triage, treat, and transport patients with traumatic injuries to the most appropriate facility.<br>
slide37. Patient Assessment (2 of 4) Injuries to the head
Disability and unseen injury to the brain may occur.
Bleeding or swelling inside the skull from brain injury is often life threatening.
Injuries to the neck and throat
Injuries may result in an airway problem.
Use DCAP-BTLS.
Always use an occlusive dressing on any open neck wound.<br>
slide38. Patient Assessment (3 of 4) Injuries to the chest
Blunt trauma to the chest can fracture ribs or the sternum.
Large vessels of the heart may be torn.
Pneumothorax, tension pneumothorax
Hemothorax
Reassess a trauma patient’s chest region every 5 minutes.<br>
slide39. Patient Assessment (4 of 4) Injuries to the abdomen
Solid organs may tear, lacerate, or fracture.
Hollow organs may rupture and leak toxic chemicals.
Healthy young adults are able to compensate longer than others for blood loss.
Maintain a high index of suspicion.
Reassess using DCAP-BTLS.<br>
slide40. Management (1 of 2) Trauma lethal triad
Major contributor to death in patients
Factors that interfere with blood clotting will cause more blood loss.
Aggressively seek to control all bleeding.
Ensure IV fluids are warmed.
Monitor end-tidal carbon dioxide and ventilations.
Consider calling for paramedic backup. © Jones & Bartlett Learning.<br>
slide41. Management (2 of 2) Scene time
Limit on-scene time to the minimum amount.
Should ideally be less than 10 minutes
Criteria to identify a critically injured patient:
Dangerous MOI
Decreased level of consciousness
Any threats to airway, breathing, or circulation
Very young or very old
Chronic illnesses<br>
slide42. Transport and Destination (1 of 4) Type of transport
Ground or air
Several factors to be considered to use ground transportation

slide43. Transport and Destination (2 of 4) Criteria for air medical services
Distance to the trauma center is greater than 20 to 25 miles (32 to 40 km)
Patient needs medical care and stabilization at the advanced life support (ALS) level.
Traffic conditions or hospital availability
Air transport to mitigate the effect of delay caused by EMS systems
Multiple-casualty incident<br>
slide44. Transport and Destination (3 of 4) Destination selection
Know the criteria for referral to a trauma center.
