title: Endogenous ethanol production in trauma victims associated with medical treatment.
abstract: Four cases of trauma, where endogenous ethanol production was suspected to have been occurred in association with medical treatment, are reported. To discriminate endogenous ethanol produced de novo by bacteria from exogenous ethanol by drinking, various tissues and body fluids, such as brain and cerebrospinal fluid, together with blood obtained from various locations, were subjected to analysis for both ethanol and n-propanol. The first individual was a 40-year-old man who had been stabbed in the abdomen with a knife and had died of bleeding about 12 h after peritoneotomy, and autopsied 12 h later. In the heart blood, 0.44 mg/g ethanol and 0.005 mg/g n-propanol were detected. Ethanol levels in the cerebrospinal fluid, vitreous humor and brain, reflecting exogenous ethanol levels, were 0.08-0.16 mg/g, and no n-propanol was detected in any of the specimens. The second individual was a 45-year-old man who had been punched hard in the head and face and had died of traumatic shock about 12 h after hospitalization, and autopsied 12 h later. The heart blood concentrations of ethanol and n-propanol were 0.15 and 0.008 mg/g respectively, and a subdural hematoma contained only 0.05 mg/g ethanol and non n-propanol. The third individual was a 34-year-old man who suffered incised wounds of the left arm and head with a sickle and had died of hemorrhagic shock. In the heart blood, 0.30 mg/g ethanol and 0.026 mg/g n-propanol were detected; there was 0.04 mg/g ethanol and no n-propanol in the brain. The fourth individual was a 76-year-old woman who had been hit by a motorcycle and had died of liver rupture about 1 h after admission to a hospital. The heart blood contained 0.22 mg/g ethanol and 0.002 mg/g n-propanol. Only a trace of ethanol and no n-propanol were detected in the pericardial sac fluid and cerebrospinal fluid.
