Flashcards in Scene size-up Deck (14)
Steps of scene size-up:
1. Standard precautions.
2. Scene safety.
3. Initial triage.
4. Need for more help or equipment.
5. Mechanism of injury.
Steps of ITLS Primary Survey:
Perform a scene size-up.
Perform initial assessment.
Perform a rapid trauma survey or focused exam.
Make critical interventions and transport decision.
Contact medical direction.
2. Long back board with effective strapping and head motion-restriction device.
3. Appropriately sized rigid cervical extraction collar.
4. O2 and airway equipment.
5. Trauma box.
Mechanism of injury:
The means by which the patient was injured.
Kinetic energy = 1/2 (M X V2)
Potential injury patterns for frontal impact
(Deformed steering wheel, dashboard knee imprints, spiderweb deformity of windscreen):
Spleen / liver laceration
Posterior hip dislocation
Potential injury patterns with lateral impact (T-bone)
Contralateral neck sprain
Lateral flail chest
Laceration of spleen, liver, kidney
Potential injury patterns for rear impact:
Potential injury patterns for ejection:
Exposure to all mechanisms and mortality increased
Potential injury patterns for pedestrian vs. car:
Abdominal visceral injuries
# lower extremities and pelvis
3 separate events for MVA:
Organ collision resulting in rupture, shearing and bruising
Basic mechanisms of blunt motion injuries:
Rapid forward decelerations (collisions)
Rapid vertical decelerations (falls)
Energy transfer from blunt instruments (blackjack, baseball bat)
Frontal impact or head-on collision
Lateral impact or T-bone collision
Basic mechanisms of penetrating motion injuries:
Falls on fixed objects
