Study Notes
Motor Vehicle Crashes and Injuries
- Rollover crashes significantly increase the risk of ejection, leading to serious injuries or death.
- Internal assessments in crashed vehicles help EMTs predict potential injuries by identifying contact points.
- The severity of deceleration injuries can be reduced by airbags, which cushion the impact.
- In incidents with fatalities, all surviving occupants are likely to have sustained similar trauma.
Trauma Centers
- Adult trauma patients with a GCS score of 13 or lower should be transported to the highest-level trauma center available.
- Level 1 trauma centers are required to have general surgeons present 24 hours a day, unlike level 3 centers.
Patient Assessment and Injuries
- The force over a distance is defined as work, crucial for understanding trauma dynamics.
- When assessing falls, factors such as the height of the fall are relevant; the speed is not as critical.
- For elderly patients, osteoporosis presents a risk where even minor falls can lead to fractures.
- The index of suspicion refers to an awareness of potential serious injuries during assessments.
Kinetic Energy and Mechanics
- Kinetic energy describes the energy of a moving object and increases exponentially with speed; if speed doubles, kinetic energy quadruples.
- In vehicle collisions, the mechanism of injury can be assessed by examining damage within the vehicle.
Gunshot and Blast Injuries
- Gunshot wounds can result in unpredictable internal injuries due to bullets tumbling or ricocheting.
- The phenomenon of cavitation involves pressure waves from a bullet causing damage distant from the initial path.
- Signs of pulmonary blast injury include coughing up blood; it is crucial to avoid providing oxygen under positive pressure in these cases.
Trauma Response
- Rapid transport to a trauma center is critical for the outcome of patients with multisystem trauma.
- Deployment of airbags is less indicative of high-energy trauma compared to other signs, such as vehicle damage.
