Questions and Answers

A man jumped from the roof of his house and landed on his feet. He complains of pain to his heels, knees, and lower back. This mechanism of injury is an example of:

  • Hyperflexion
  • Hyperextension

  • 3 (correct)
  • 4

    Study Notes

    Mechanisms of Injury

    • Axial loading occurs when a person lands directly on their feet from a height, often causing injury to lower extremities and back.
    • Hyperextension spinal injuries frequently result from hangings.

    Head Injury Assessment

    • An abnormal flexion response in extremities indicates a motor response score of 3 on the Glasgow Coma Scale (GCS).
    • Rapid deterioration of neurological signs can suggest an expanding intracranial hematoma.
    • Common indicators of serious head injuries include CSF leakage from ears, decerebrate posturing, and widening pulse pressure; a rapid, thready pulse is not typical.

    Helmet and Patient Management

    • Tight-fitting motorcycle helmets should remain unless airway assessment is hindered by the helmet.
    • In cases of severe head trauma with airway issues, suctioning the oropharynx may be necessary for up to 15 seconds.

    Structural Considerations

    • The central nervous system comprises the brain and spinal cord.
    • The spinal column consists of five sections: cervical, thoracic, lumbar, sacral, and coccygeal, listed from top to bottom.
    • The sympathetic nervous system activation excludes pupillary constriction, which is typically a parasympathetic response.

    Moving and Immobilization Techniques

    • The ideal method to transfer an injured patient to a backboard is the four-person log roll technique.
    • Once a cervical collar is applied, it should only be removed if airway management is compromised.

    Breathing Patterns and Secondary Injuries

    • Irregular breathing, with variable patterns and apnea, signals increased intracranial pressure.
    • Secondary brain injury is often caused by hypoxia and hypotension, rather than being a direct result of the initial trauma.

    Patient Signs and Recommendations

    • A slow pulse in a patient with a head injury raises concern for significant brain injury.
    • If bloody fluid drains from an ear, it may indicate tympanic membrane rupture following head impact.
