Trauma to the Head, Neck & Spine Flashcards
Nervous System Overview
• Controls thought, sensations, and motor
functions
Central nervous system
– Brain, spinal cord
Peripheral nervous system
– Vertebral nerves
– Cranial nerves
– Body’s motor and sensory nerves
Anatomy of the Head - what are the bones
• Cranium • Facial Bones (14) – Mandible – Maxillae – Nasal bones – Malar (zygomatic)
Anatomy of the Spine - Vertebrae - what are the bones
– Cervical (7) – Thoracic (12) – Lumbar (5) – Sacral (5) – Coccyx (4)
Scalp Injuries- characteristics
– Lots of blood vessels
– Profuse bleeding
Skull Injuries - types
– Open head injury
– Closed head injury
Traumatic Brain Injuries (TBI) - types
– Concussion – Contusion • Coup • Contrecoup – Laceration – Hematoma • Subdural Hematoma • Epidural Hematoma • Intracerebral Hematoma
Think about it - Trauma to the Head, Neck & Spine
- Does my patient have a serious or potentially serious head injury? Should the patient be transported to a trauma center?
- Do my patient’s complaint and MOI indicate spinal stabilization? Is immobilization warranted?
Injuries to the Head & Face
• Cranial injuries with impaled objects – Stabilize object in place • Injuries to the face and jaw – Primary concern: Airway – When possible, position to allow for drainage from mouth
Nontraumatic Brain Injuries
- Many signs of brain injury may be caused by an internal brain event (hemorrhage, blood clot)
- Signs are the same as for traumatic injury, except no evidence of trauma and no MOI.
Glasgow Coma Scale (GCS)
• May use GCS in addition to AVPU for ongoing neurological assessment
• Considerations for use of GCS
– Eye opening
– Verbal response
– Motor response
• Do not spend extra time at the scene calculating
Wounds to the Neck
- Large, major vessels close to surface create the potential for serious bleeding
- Pressure in large vein is lower than atmospheric pressure
- Great possibility of air embolus being sucked through
- Treatment: stop bleeding, prevent air embolism
Treatment: Open Neck Wound
- Ensure open airway
- Place gloved hand over wound
- Apply occlusive dressing
- Apply pressure to stop bleeding
- Bandage dressing in place
- Immobilize spine if MOI suggests cervical injury
Injuries to the Spine
• Assume possible cervical-spine injury if MOI exerts great force on upper body or if soft-tissue damage to head, face, or neck
• Spinal cord is a relay between most of body and brain for sending messages
• Neurogenic shock: form of shock resulting from nerve paralysis; causes uncontrolled
dilation of blood vessels
Assessment: Spinal Injury - what to consider
- Paralysis of extremities
- Pain without movement
- Pain with movement
- Tenderness anywhere along spine
- Impaired breathing
- Deformity
- Priapism
- Loss of bowel or bladder control
Treatment: Spinal Injury
- Provide manual in-line stabilization
- Assess ABC’s
- Rapidly assess head and neck; apply rigid cervical collar
- Rapidly assess for sensory and motor function
- Apply appropriate spinal immobilization device
- Reassess sensory and motor function
Steps for Applying a Cervical Collar
• Always maintain manual stabilization
• Use in conjunction with a long
backboard
Immobilizing a Seated Patient
• Low priority: Use a short board or vest-immobilization device
• High priority: Maintain manual
stabilization while moving patient
