Complications following extradural haemorrhage (operated) sustained in an electric scooter incident (rider)
AI-generated summary
A 39-year-old man died from complications of extradural haemorrhage sustained in an e-scooter fall. He was riding a high-powered e-scooter (capable of 84 km/h, exceeding legal limits) while under the influence of methylamphetamine, without a helmet. He initially presented to ED with GCS 13 but rapidly deteriorated to GCS 4 with fixed dilated pupil, indicating critical intracranial injury. CT imaging revealed large extradural haemorrhage with midline shift, base of skull fracture, and subarachnoid haemorrhage. He underwent emergency craniotomy at The Alfred Hospital but experienced minimal neurological recovery. Treatment was withdrawn after poor prognosis discussion with family. Clinical lessons: high-speed e-scooter use poses significant head injury risk; drug impairment substantially increases crash risk; helmet use is critical—studies show traumatic brain injury rates of 24.5% without helmets versus 5.3% with helmets; rapid clinical deterioration in head injury patients requires urgent imaging and neurosurgical consultation.
