Study Notes
Spinal Cord and Protection
- The spinal cord is protected by the spinal canal.
- A cervical collar should only be removed if it hinders airway management (ABCs).
Patient Immobilization
- Apply a cervical collar after assessing distal neurovascular functions.
- Short backboards or vest-style devices are suitable for clinically stable patients in a sitting position.
Central Nervous System (CNS)
- The most protected part of the CNS is the brain stem, vital for cardiac and respiratory functions.
- The CNS comprises the brain and spinal cord.
Head Injuries and Hematomas
- An epidural hematoma occurs due to bleeding between the skull and dura mater.
- Rapid head deceleration leads to anterior compression injuries and posterior stretching or tearing.
Assessment of Head Injury
- Thin, bloody fluid from the ear suggests tympanic membrane rupture due to head impact.
- Avoid excessive pressure on scalp lacerations with potential skull fractures.
Nervous System Response
- Activation of the parasympathetic nervous system results in decreased heart rate and dilated blood vessels.
Vital Signs and Cushing's Triad
- Cushing's triad is characterized by elevated blood pressure (190/110 mm Hg), bradycardia (pulse 55 beats/min), and irregular respirations (30 breaths/min).
Ventilation in Head-Injured Patients
- The efficacy of positive-pressure ventilation in head-injured patients can only be determined through appropriate assessment methods.
