A broad classification that includes any injury to the head as a result of trauma
head injury
Most common cause of TBIs is
falls
Groups at highest risk for TBI include
0-4 y/o
15-19 y/o
65 above y/o
MALE
what is the best approach for head injury
prevention
consequence of direct contact to head/brain during the instant of initial injury
primary injury
what type of injury: contusions, lacerations, external hematomas, skull fractures, subdural hematomas, concussion, diffuse axonal
primary injury
what type of injury: damage evolves over ensuing days and hours after the initial injury
secondary injury
what type of injury: caused by cerebral edema, ischemia, ог chemical changes associated with the trauma
secondary injury
a bruising of the brain surface
contusion
a temporary loss of neurologic function with no apparent structural damage to the brain
concussion
a transient period of unconsciousness following A VIOLENT BLOW TO THE HEAD
concussion
involves localized bleeding and swelling in the brain tissue, which can lead to more severe complications
contusion
tend to bleed heavily and portals of infection
scalp wounds
ecchymosis behind the ear
battle signs
halo sign-ring of fluid around the blood stain from drainage
csf leak
also called as raccoon eyes or black eye
periorbital hematoma
acceleration/deceleration injury occurs when the head accelerates and then rapidly decelerates, damaging brain tissue
closed TBI
blunt trauma
closed TBI
object PENETRATES the brain or trauma is so severe that the scalp and skull are opened
OPEN TBI
contusion or concussion
more severe injury with possible surface hemorrhage
CONTUSION
contusion or concussion
a temporary loss of consciousness with no apparent structural damage
concussion
widespread axon damage in the brain seen with head trauma
diffuse axonal injury
TYPES OF INTRACRANIAL BLEEDING
epidural
subdural
intracerebral
blood collection in the space between the skull and the dura
epidural
