Study Notes
Traumatic Brain Injury (TBI)
- TBI results from external forces causing alterations in brain function.
- Non-Traumatic Brain Injury (NTBI) includes internal injuries like strokes and tumors.
- Distinction between head injuries and TBIs: head injuries may occur without brain damage.
Types of TBI
- Open TBI: Skull is fractured, allowing penetration of brain tissue; disrupts dura mater.
- Closed TBI: Skull remains intact while internal brain injury occurs.
- Mild TBI: Accounts for 80% of cases, often including head contusions.
- Moderate and Severe TBI: Each constitutes 10% of cases.
Epidemiology
- Leading cause of death and disability in the U.S.; falls among the elderly account for a significant rise.
- Key causes include being struck by objects, motor vehicle accidents, assaults, and self-harm.
Subjective Examination
- Gather patient demographics, chief complaints across neuromuscular, cognitive, neurobehavioral, and communication domains.
- Utilize RLA (Rancho Los Amigos) Level 7 & 8 for assessing consciousness and responsiveness.
Neurological Examination Components
- Evaluate orientation (person, place, time, situation) and attention span.
- Assess memory through long-term memory (LTM), short-term memory (STM), and recall.
- Test general information understanding, basic calculation skills, abstract thinking, and judgment.
Glasgow Coma Scale (GCS)
- Widely used tool to assess the severity of brain injury.
- Scores range from 3 (lowest, indicating deep coma) to 15 (highest, indicating full consciousness).
- Prognosis for recovery correlates with the initial GCS score, particularly motor and eye response.
Signs of Injury
- Bruising around the eyes (Raccoon’s eyes/Panda bear sign) and behind the ears (Battle Sign) can indicate skull fractures.
- Note any swelling and diaphoresis, which may signal increased sympathetic activation.
Respiratory Patterns
- Assess breathing patterns and document if the patient is intubated or breathing spontaneously.
- Recognize abnormal patterns like Cheyne-Stokes and erratic breathing and their implications.
Psychological Changes
- Mood swings and behavioral issues may arise post-injury; relatives often note these changes.
- Observe for lability, where patients may display unexpected emotional responses.
Cognition and Prognosis
- Inquire about levels of consciousness during the injury; longer unconsciousness typically leads to poorer outcomes.
- Note the sequence of recovery during assessment, such as the emergence of eye opening without cognitive function.
Objective Component
- Familiarize with patient attachments (e.g., ventilators, tracheostomy tubes) in acute care settings.
- Ensure proper attachment of critical elements; report any dislodgements to nursing staff promptly.
