Effect of alcohol in blood on neurological outcome and survival of patients with combination of polytrauma and head injury

The association between blood alcohol level (BAL) on mortality and neurologic outcome in patients with polytrauma and head injury is not clear and the data in the literature are sometimes conflicting. Some studies suggest a possible neuroprotective effect of alcohol and increased survival while others show the opposite. The rationale for this study was to investigate whether BAL has any impact on presentation, neurologic outcome and survival in patients with combination of polytrauma and head injury.
