Traumatic Brain Injury
Consider NAI
Leading cause of death and disability from trauma
GCS 15: 3% risk
GCS 14 9% risk
GCS 13 27% risk
Ix
CT for acute bleed
MRI less sensitive particularly early
May occur with or without skull fracture
Complication of skull fracture: growing skull fracture
Subgleal
Subperiosteal: doesn't cross suture lines
Extradural (aka epidural): lentiform doesn't cross suture lines (particularly parietal > middle meningeal artery bleed)
Subdural: not in gyri (veins between dura and arach)
Subarachnoid: in gyri
Parenchymal
Intraventricular
PTA testing
Post-traumatic amnesia
