Head and Spinal Injuries Flashcards
Head injuries include trauma to what?
scalp, skull, brain
Scalp Injuries can be….
open or closed
Why does the scalp bleed heavily?
the scalp is highly vascular
Skull fracture is an indication of what?
injury to the brain
Linear Fracture
do not present with deformity or depression
Depressed Fracture
noticeable upon palpation and has an increased risk of brain injury
Basal Skull Fracture
Occur at the base of the skull
cerebrospinal fluid may leak from nose and ears
bruising behind ears
raccoon eyes
Concussion
temporarily cause brain function to be disrupted
Signs and Symptoms of Concussion
Altered mental status
brief loss of consciousness
nausea
vomiting
Anterograde Amnesia
cant remember what happened after the injury
Retrograde Amnesia
Cant remember events before the injury
Cerebral Contusion is accompanied by
edema and/or concussion
Epidural Hematoma
bleeding beneath the skull but above the dura mater
Epidural Hematoma includes significant
arterial bleeding
Epidural Hematoma increases
intracranial pressure
Epidural Hematoma is often accompanied by
temporal skull fracture
Subdural hematoma
Bleeding above the brain
beneath the dura mater and above the arachnoid meningeal layer
Subdural Hematoma is often caused by
venous bleeding following cerebral contusion
Subarachnoid Hemorrhage
bleeding within the subarachnoid space
Subarachnoid Hemorrhage allows blood to enter the
cerebrospinal fluid
Intracerebral Hemorrhage
bleeding within the brain tissue
Intracerebral Hemorrhage has a high….
mortality rate
Herniation Syndrome
when the brain is compressed due to excessive intracranial pressure
Cushings Response
Hypertension
Bradycardia
Altered respiratory pattern
