Subdural Hematoma Occurrence: Comparison Between Ethanol and Cocaine Use at DeathHeninger, Michael MDThe American Journal of Forensic Medicine and Pathology: September 2013 - Volume 34 - Issue 3 - p 237–241 doi: 10.1097/PAF.0b013e3182834b32 Original Articles Abstract Author Information Objective The objective of this study was to show that, in a medical examiner population, ethanol intoxication is associated with an increase in the occurrence of subdural hematoma (SDH), whereas the presence of cocaine is not associated with an increase in the occurrence of SDH. Design This was a retrospective evaluation of 967 SDH including the investigative information, autopsy, and toxicological findings derived from 18,314 medical examiner cases over 8 years. Results Subdural hematoma is found in 7% to 9% of cases with either no ethanol or less than 100 mg/dL of ethanol. Subdural hematoma is found in 18% of cases with ethanol levels of greater than 100 mg/dL. Subdural hematoma is found in 11% of cases negative for cocaine, whereas SDH is found in 9% of cases with any form of cocaine present at death.
