Study Notes
Vehicle Manufacturing and Injuries
- Vehicle manufacturing today allows for limited antero-posterior movement due to superior cerebral vein attachments and lateral gliding restricted by the falx cerebri.
Leading Causes of Traumatic Brain Injury (TBI)
- Unintentional falls are the primary cause, especially among the elderly and children.
- Motor Vehicle Accidents (MVAs) rank second, particularly among young adults.
- Fatalities from MVAs are significantly influenced by alcohol intake and various risk factors like ADHD, anti-social behavior, firearm use, and lower socioeconomic status.
- Struck by an object incidents occur frequently in sports and assaults.
Brain Lobes and Their Functions
- Frontal Lobe: Responsible for intelligence and cognitive functions such as judgment, long-term memory, critical thinking, calculations, communication, and personality development.
- Also involved in planning, programming, and execution of motor movements.
Classification of TBI
- Mild TBI: Duration of symptoms less than 1 day.
- Moderate TBI: Symptoms lasting more than 1 day but less than 7 days.
- Severe TBI: Symptoms persist for more than 7 days.
Blast Injury
- Significant concern in military contexts due to frequent exposure to explosives, leading to unique injury mechanisms.
- Includes primary injuries from direct blast overpressure and secondary injuries from shrapnel or flying debris.
- Tertiary injuries occur when victims are thrown against objects, and quaternary injuries stem from asphyxia and toxic inhalant exposure.
Memory Loss Types
- Retrograde Amnesia: Loss of prior memories occurring after an accident.
- Anterograde Amnesia: Inability to learn new information post-injury.
Ancillary Procedures Post-TBI
- Skull X-rays to identify fractures or lesions.
- CT Scans for tumors, hemorrhage, and cerebral edema.
- Mean Arterial Pressure (MAP) calculated to assess perfusion efficiency for vital organs.
Patient Assessment and Examination
- Vital signs may show increased readings indicating potential dysautonomia.
- Assessments focus on responsiveness, capacity to follow commands, and observable cognition levels.
Rehabilitation and Care Approaches
- Engage caregivers to help with patient instruction and to create familiarity during treatment.
- Recommended to keep stimulation low, avoid overwhelming sensory input, and structure activities to reduce agitation.
- Emotions and behaviors can be unpredictable, thus requiring gentle and adaptive approaches to therapy.
Documentation
- Accurate documentation of patient responses and treatment progress is essential, especially under conditions of agitation or confusion.
- Regular assessment of range of motion and responsiveness is critical, as varying levels of arousal can influence care insights.
