1

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.

2

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.

3

Essential equipment:

1. PPE
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.

4

Mechanism of injury:

The means by which the patient was injured.

Kinetic energy = 1/2 (M X V2)

5

Potential injury patterns for frontal impact
(Deformed steering wheel, dashboard knee imprints, spiderweb deformity of windscreen):

C-spine #
Flail chest
Myocardial contusion
Pneumothorax
Aortic disruption
Spleen / liver laceration
Posterior hip dislocation
Knee dislocation

6

Potential injury patterns with lateral impact (T-bone)

Contralateral neck sprain
C-spine #
Lateral flail chest
Pneumothorax
Aortic disruption
Diaphragmatic rupture
Laceration of spleen, liver, kidney
Pelvic #

7

Potential injury patterns for rear impact:

C-spine injury

8

Potential injury patterns for ejection:

Exposure to all mechanisms and mortality increased

9

Potential injury patterns for pedestrian vs. car:

Head injury
Aortic disruptions
Abdominal visceral injuries
# lower extremities and pelvis

10

3 separate events for MVA:

Machine collision
Body collision
Organ collision resulting in rupture, shearing and bruising

12

Basic mechanisms of blunt motion injuries:

Rapid forward decelerations (collisions)
Rapid vertical decelerations (falls)
Energy transfer from blunt instruments (blackjack, baseball bat)

13

MVAs forms:

Frontal impact or head-on collision
Lateral impact or T-bone collision
Rear-impact collision
Rollover collision
Rotational collision

14

Basic mechanisms of penetrating motion injuries:

Projectiles
Knives
Falls on fixed objects

15

What do you do when you approach a scene in your vehicle?

1. Determine nearest safe place to park.
2. Park facing away from scene.
3. Determine safety to approach patient.
4. Windshield survey.
