Study Notes
Cerebral Injuries
- Subdural hematoma affecting the pupil and limb can cause unequal pupil size and limb weakness.
Subarachnoid Hemorrhage Symptoms
- Symptoms of subarachnoid hemorrhage include severe headache, stiff neck, and vomiting.
Injuries Causing Intracerebral Laceration
- Intracerebral laceration can result from penetrating injuries, such as gunshot wounds or stab wounds.
Management of Protruding Foreign Bodies
- Protruding foreign bodies found in the skull should not be removed, as this can cause further injury.
Prognosis of Gunshot Wounds and Fragment Wounds
- The prognosis of gunshot wounds and fragment wounds is determined by the velocity and kinetic energy of the projectile.
Defining Characteristics of Concussion
- Concussion is defined by a brief loss of consciousness or transient alteration of consciousness.
Condition Resulting from Tearing of Brain Fibers
- Diffuse axonal injury results from tearing of the brain's long connecting nerve fibers.
Symptom of Extradural/Epidural Hematoma
- Typical symptom of extradural/epidural hematoma is a lucid interval followed by rapid deterioration.
Causes of Contusions in the Brain
- Contusions in the brain are caused by coup or countrecoup injuries, which occur when the brain collides with the skull.
Brain Injuries Requiring Rapid Evacuation
- Extradural/epidural hematoma requires early diagnosis and rapid evacuation to a surgical unit.
