2. §Identify common mechanisms of injury (MOI)***** (MVA, drowning, blunt injury, adult vs
child, size of vehicle & size of person, etc).
§Describe primary & secondary assessments of trauma patients.
§Identify appropriate nursing diagnosis and expected outcomes based on assessment of the
trauma victim.

§Nursing Diagnosis
§Expected Outcomes
§Planning
§Implementation
§Evaluation!!!

4. §Unintentional injury:leading cause of premature
death (all ages).
§MVAs account for the majority of unintentional
injuries (41%) and traumatic deaths (44%).
§MVC&firearms: leading cause of death ages 16-24
§Homicide is the 2ndmost common cause of death.
§Death by firearms represents approx. 80% of ALL
homicides.

5. §Intentional or unintentional wound or injury inflicted on the body from a mechanism against which the body cannot protect itself.
§4thleading cause of death in U.S.
FOURMAJORMECHANISMSOFINJURY:
§Poisoning from alcohol or drugs
§MVAs
§Firearms
§Falls

6. PREVENTION:
Overarchinggoalintraumacare.
§Education
§Legislation
§Automatic protection
However, once a traumatic injury
occurs, the priority is early &
aggressive intervention.

PRIMARY PREVENTION: prevents the event
fromoccurring.
•Driving safety classes
•Speed limits
•Drug awarenesscampaigns
•Domestic violencecampaigns
•Fall prevention
SECONDARYPREVENTION: strategies to
minimize the impact of the traumatic event.
•Seat belt use
•Car seats
•Air bags
•Helmets
•Antibullying hotlines
TERTIARYPREVENTION: interventions to
maximize pt outcomes after a traumatic
event.
•Emergency response systems
•Medical care
•Rehabilitation

9. §Age: a leading cause of death under age 44.
§Socioeconomic status and race
§Firearms
§Alcohol and drug use
§Geography: rural (farm accidents) vs. urban (lead pipes, crime)
§Temporal: pattern & timing

10. Definition: Transfer of energy causing injury to human tissue
§Kinetic
§Thermal
§Electrical (alternating current is worse)
§Chemical (asbestos, chemistry, rat poison)
§Radiation (sunburn, x-ray)

11. MECHANISM OF INJURY
§Transfer of energy from external
forces to the human body.
§Mechanism of injury (MOI) is
primary concern in assessment!!

13. Blunt:
§Acceleration
§Deceleration
§Shearing (tissue, vessels, aorta)
§Crushing
§Compression (landing on your
feet after jumping off a roof)

14. Penetrating:
§Impalement from foreign objects.
§Easily diagnosed due to obvious signs of injury.
§Low Velocity: Stab Wounds, less force
§High Velocity: Ballistics, more force
oEntrance wounds (direct insult, smaller)
oExit wounds (larger)

15. Blast Injuries:
§Blunt and Penetrating
§Primary (positive pressure of shockwave)
§Secondary(lung contusions, negative
pressure of shockwave, penetrating injuries)
§Tertiary(tissue damage, visceral organ
damage, head injury)
§Quaternary(biological exposure, chemical,
thermal)

17. §Minor Trauma
§Major Trauma
Injury Scoring Systems:
oAbbreviated Injury Scale (AIS)
oInjury Severity Score (ISS)
oGlasgow Coma Scale (GCS): 3 to 15
oRevised Trauma Score (RTS): includes hemodynamics (BP, HR) plus GCS

18. §Organized approach to trauma care
§Prevention
§Access
§Acute hospital care
§Rehabilitation
§Research activities

19. §EMS –Care at scene and transport
§ABCs with cervical spine immobilization.
§Trauma Care Centers:Reduced
preventable rate from 40% to 4%.
oLevels I-IV
oTrauma Team
oDisaster Plans
***VERY ORGANIZED!

20. DISASTER:
§Sudden event, resources
overwhelmed by demands.
§Classified by number of victims.
§Mass patient incident (<10)
§Multiple casualty incident (10-100)
§Mass casualty incident (>100)

21. §High incidence of death &
disabilityàBIGEXPENSE!
§First Peak –death occurs in
seconds to minutes.
§Second Peak –death occurs in
minutes to several hours.
§Third peak—occurs several days
to weeks after initial injury.
First hour of emergent care-“Golden Hour”

22. Primary assessment is KEY–rapid survey of initial injuries with life saving interventions.
§Airway w. cervical spine immobilization
§Breathing
§Circulation w. hemorrhage control
§Disability or neurological status (GCS, RTS)
§Environment & exposure

23. A -AIRWAY
§Airway patency
§Jaw-thrust maneuver
§Inspect and remove foreign bodies
§Airway obstruction (complete, partial)
§Airway adjuncts
§Inhalation injury
§Manual C-spine immobilization in neutral position
NGT to decompress stomach & prevent emesis / aspiration.

24. B -BREATHING
§Assess adequacy of ventilation
§Skin color, respiratory rate, depth,
effort of respirations
§Grunting, wheezing, use of
accessory muscles
§Breath sounds-auscultate
§Chest symmetry and expansion

25. IMPAIRED BREATHING
§Pneumothorax
§Hemothorax
§Tension pneumothorax
§Sucking chest wound
§Flail chest

26. IMPAIRED BREATHING
INTERVENTIONS:
•NRB(15 L/min O2)
•Inadequate respirations: BVM
•No spontaneous respirations:
intubate patient
•Treat underlying cause

28. C -CIRCULATION
§Assess adequacy of circulation
§Pulse presence, rate and quality
§Inspect skin color, moisture & temp.
§Observe for uncontrolled bleeding and
apply pressure

29. IMPAIRED CIRCULATION
§IF NO PULSE…initiate cardiac compressions!!
§Volume repletion:
•Initiate 2 large bore IV’s with fluid bolus of warm NS or LR
•Blood products
§Control any uncontrolled bleeding

30. HYPOVOLEMIC & HEMORRHAGIC SHOCK:
§External or internal hemorrhage
§Pneumatic anti-shock garment-(rare)
§Identify&treat the cause
§Fluid replacement with crystalloids:
o3:1 RULE à3mL IV crystalloid for every 1mL estimated blood loss
§Blood products
§Tachycardia, narrow pulse pressure, tachypnea, decreased urine output.
o↓ CO
o↑ HR, ↑ RR
o↓ U/O

31. CALCULATION OF MAP:
MAP: assessment of tissue perfusion
Calculate: 90/60
o90 –60 = 30
o1/3 of 30 = 10
o60 + 10 = 70

§P –painful stimulus
§U -unresponsive

§Facilitate family involvement,
provide updates

HISTORY:
Pre-hospital Information –MIVT
§Mechanism and pattern of injury

§Past Medical History

38. §Inspect, Auscultate, Palpate

oChest
oAbdomen / Flanks
oPelvis / Perineum

H –HISTORY & HEAD-TO-TOE

39. I –INSPECT POSTERIOR SURFACES
§Maintain C-Spine Immobilization
§Support extremities with suspected injuries
§Logroll –Maintain vertebral alignment
oNeed three people!!
Palpate:
§Vertebral column
§Posterior surfaces
§Anal sphincter

42. §Radiological studies per trauma protocol
§CT Scan
§Tetanus toxoid vaccination
§Risk for infection
§Hypothermia
§Respiratory complications

43. §AKI: hypoperfusion or trauma, pre-renal and intra-
renal causes.
§Nutritional support: started within 24-48 hrs to
assist with healing & meeting metabolic demands.
§MODS

44. Effects of aging: Fallsare the most frequent causes of injury in the elderly.
•Fallsaretheleading cause of injury-related deaths in ppl. >65 y.o.
•Physiological changes predispose elderly pts to serious injuries, prolonged recovery,
and higher mortality rates.
•Have worse outcomes after trauma r/t poor functional status and comorbidities.
Alcohol and drug use: contributing factor to many traumas/injuries.
§Assess pt hourly for S&S of withdrawal (tachycardia, HTN, N/V/D, diaphoresis, seizures,
agitation, confusion, hallucinations)
Family and Patient Coping:traumatic event often creates a crisis within the family.
•Promote consistent communication btwn. HC members & the family.
•Involvethesocialworkearlyontoassist thept/ family withcoping&decisionmaking.
