Electric scooter - related CT - positive brain injuries: a five - year single - centre experience overview.

The popularity of electric scooters (ES) during the last five years due to climate neutrality and public availability led to increased numbers in traffic accidents with significant injuries. This study was conducted to overview e-scooter related computed tomography (CT) positive traumatic brain injuries, exploring circumstances, clinical course, outcomes and possible relations to behavioral patterns. We retrospectively reviewed medical data of all patients treated in our center during the period 2019 to 2023, medical records were analysed and statistically processed. This review included 45 patients, 75.7% were males and median age was 40 years old. Patient numbers did not differ between weekdays, working days versus weekends and time of the day. Eighty percent of patients were injured from falling off the scooter, the rest were hit by another vehicle while riding. None of the patients were known using helmet, significant alcohol intoxication was found in 68.8% of cases. The most common traumatic intracranial features were subarachnoid hemorrhage (55.6%), followed by brain contusions (48.9%), epidural (26.7%), subdural (26.7%) hemorrhages. Age had a positive correlation with alcohol intoxication (r = 0.596, p = 0.007) and poor outcomes (r = 0.522, p = 0.004), also, men over 40 years old were more likely to undergo surgery (p = 0.024), meanwhile operated patients suffered more infections (p = 0.011) and more often ended with poor outcomes (p < 0.001).
