TBI and Subdural Hematoma Vocabulary

Vocabulary flashcards covering key definitions, GCS classifications, clinical signs, interventions, and complications related to traumatic brain injury and subdural hematoma.

Traumatic Brain Injury (TBI)

Brain dysfunction from an external force such as a fall, collision, or impact.

Mild TBI GCS Range

A Glasgow Coma Scale score range of $13\text{--}15$.

Moderate TBI GCS Range

A Glasgow Coma Scale score range of $9\text{--}12$.

Severe TBI GCS Range

A Glasgow Coma Scale score range of $3\text{--}8$.

Subdural Hematoma

Bleeding between the dura and arachnoid, often resulting from torn bridging veins.

Older Adult Subdural Hematoma Risk Factors

Falls, cerebral atrophy/bridging vein vulnerability, and possible anticoagulant use.

Findings of Worsening TBI or Hematoma

Declining LOC, worsening headache, vomiting, new weakness, pupil changes, and seizures.

First Priorities After Head Trauma

Airway/cervical spine precautions as indicated, breathing, circulation, and serial neurologic assessment.

Anticoagulation Significance in Head Trauma

History of anticoagulation that increases concern for intracranial bleeding.

Purpose of CT in Head Injury

To identify acute intracranial hemorrhage and structural injury following a concerning head injury.

Management of Large Subdural Hematomas

Surgical evacuation/decompression when indicated.

Complications Requiring Ongoing TBI Assessment

Increased ICP, seizures, neurologic deterioration, cognitive/behavioral deficits, and impaired mobility.

Discharge Teaching for Mild Head Injury

Instructions to recognize worsening headache, repeated vomiting, confusion, weakness, seizures, or declining alertness and seek urgent care.
