Abstract Objective: The influence of blood alcohol level (BAL) on outcome remains
unclear. This study investigated the relationships between BAL, type and number
of diffuse axonal injury (DAI), intraventricular bleeding (IVB) and 6-month
outcome. Methods: This study reviewed 419 patients with isolated blunt traumatic
brain injury. First, it compared clinical and radiological characteristics
between patients with good recovery and disability. Second, it compared BAL among
DAI lesions. Third, it evaluated the correlation between the BAL and severity of
IVB, number of DAI and corpus callosum injury lesions. Results: Regardless of
BAL, older age, male gender, severe Glasgow Coma Scale score (<9), abnormal
pupil, IVB and lesion on genu of corpus callosum were significantly related to
disability. There were no significant differences between the BAL and lesions of
DAI. Simple regression analysis revealed that there were no significant
correlation between BAL and severity of IVB, number of DAI and corpus callosum
injury lesions. Conclusions: Acute alcohol intoxication was not associated with
type and number of DAI lesion, IVB and disability. This study suggested that a
specific type of traumatic lesion, specifically lesion on genu of corpus callosum
and IVB, might be more vital for outcome.
