Neuro issues
- cigarette smoking: 4.7% students monthly, 2.6% weekly
- eCigarettes/vaping: 12% student monthly, 8% weekly
- binge drinking: 1 in 5 monthly. prevalent among 17+yo
- marijuana use: 23% ever, 4.1% weekly
- other drugs: 3.7% ever
TBI/head injury- define, types
define: alteration in brain function caused by external force. affect brain tissue. Blunt or penetrating injury.
- blunt/closed TBI- skull still intact
- open/penetrating TBI- skull damaged, brain exposed
types:
1. Focal TBI: localised injury
a. contusion: brain/neuron damage at impact point
- coup injury: damage at initial point of impact
- contrecoup injury: damage at point opposite to coup injury due to rebound effect
b. hematoma: blood collection
- epidural: between bone and dura
- subdural: between dura and arachnoid
- subarachnoid: between arachnoid and pia mater (blood mixed w/ CSF)
- intracerebral: within cerebral tissue
-
diffuse TBI: blunt injury causing widespread damage. concussion to severe diffuse axonal injury (DAI)
a. concussion: mild-sever (concouse coma)
b. severe: significant neuronal tearing/damage = unrecoverable coma
TBI/head injury
long term disability:
- fatigue, cognition changes, behavioural changes
- repeated TBI leads to Chronic Traumatic Encephalopathy
risk: hypoxia due to increased ICP = decreased circulation, impaired mobility, social isolation
management:
- GCS assessment
- ICP monitoring
- oxygen therapy
- positioning, slight sedation, control noise and light
- supportive care (counselling, physio/OT/SLT)
