Study Notes

Mechanisms of Injury

Energy transmission to the spine is likely the cause of back pain after a 12-foot jump.
Control of obvious bleeding in a gunshot abdomen wound is crucial, followed by assessing for an exit wound.
Blunt trauma refers to injuries caused without penetrating soft tissue or organs.

Pediatric Considerations

Spinal stabilization is vital for a 15-year-old struck by a vehicle, regardless of helmet use.
Concerns for neck and facial injuries arise in child passengers involved in car accidents, especially with improper seatbelt use.

Trauma Transport Guidelines

Adults with a Glasgow Coma Scale (GCS) score of 13 or less should be transported to the highest level trauma center.
Air medical transport should be considered when ground transport is delayed due to traffic, affecting patient outcomes.

Energy and Trauma

When vehicle speed doubles, the kinetic energy quadruples, increasing injury risk.
Potential energy is calculated as mass, gravity, and height, relevant in fall-related injuries.

Types of Injuries

Intracranial bleeding is a primary concern in patients displaying confusion and severe headache post head injury.
Aortic ruptures are commonly associated with the third collision in motor vehicle accidents.
Cavitation from penetrating injuries involves pressure waves damaging nearby structures.

Patient Assessment

The index of suspicion represents awareness of potential serious injuries during assessment.
Rollover and rotational collisions pose heightened risks for multiple impacts in vehicle accidents.

Blast Injuries

Primary blast injuries in explosions are easily overlooked but may lead to significant complications.
Symptoms of pulmonary blast injury include chest tightness and coughing blood.

Trauma Statistics

A fall from over three times a patient's height is deemed significant, with the risk of severe injury increasing.

Brain Injury Types

A coup-contrecoup brain injury describes a compression injury to the brain's anterior portion alongside stretching in the posterior part.

Critical Interventions

Rapid transport to a trauma center is essential for patients with multisystem trauma to improve outcomes.
