TBI and Spinal cord Injuries Flashcards
TBI
7 million per year, motor vehicle accidents, sports, violence
people greatest at risk OA (falls), males of all ages, adolescents 15-19
Scalp Injury
avulsion, laceration (infection and bleeding)
Concussion
temporary loss of neuro function, no structural brain damage
blunt trauma- contact sports, etc- 80% of TBIs
Open TBI
fractured/ perforated skull
Closed TBI
blunt trauma, skull is intact
Concussion symptoms
headaches, nausea, fatigue, photophobia, sound sensitivity, foggy sensation (improves with rest)
Concussion red flags
decrease in LOC, worsening headache, irritability, seizures, slurred speech, pupillary changes, numbness/ weakness in arms/ legs
Concussion- monitoring
headache, N/V, photophobia, amnesia, vision and pupil changes
awaken the pt q2h and check for difficulty speaking, confusion, severe headache
Chronic Traumatic Encephalopathy (CTE)
repeated concussions, degenerative brain disease with cerebral atrophy- found in athletes
similar to alzheimers- personality changes, memory impairments, speech and gait disturbances, Tau protein destroys brain cells
Types of skull fractures
Simple (hairline), comminuted (splintered, compound), depressed (embeds in brain tissue), basilar (base of skull)
Diagnosis of Skull fractures
CT/MRI
Symptoms of a skull fracture
localized pain, headache, bleeding/ drainage from nose/ ears (may cause meningitis), battle’s sign (ecchymosis at mastoid), raccoon eyes
If CSF leak is suspected in the nose, what is contraindicated?
NG tube, nose suctioning, NOTHING in the nose
Dextrostix
diagnostic for CSF, determines if sugar is present in fluid
Halo Sign
if you allow leaking fluid to drip on a gauze pad, if the blood coalesces to the center and a yellow ring encircles the blood, the ring is CSF
Cerebral contusion
more common in frontal and temporal, may cause altered LOC, cerebral edema, cerebral hemorrhage, elevated ICP
Coup
contusion found at the site of impact
Contrecoup
location opposite the site of impact
