[Ethanol concentrations in multi-site sampling blood in forensic autopsy cases--a retrospective analysis over a period of six years (1994-1999) in Kumamoto University].
Ethanol and n-propanol concentrations in forensic autopsy cases determined in Department of Forensic Medicine, Kumamoto University School of Medicine were reviewed retrospectively. Out of 388 autopsies in 6 years (1994-1999), ethanol was positive in 88 (22.7%) cases. Higher positive rates were observed in bleeding and burning cases compared to other cases. Histograms of the blood ethanol concentrations in all ethanol positive cases had two peaks at 0.1 mg/ml to 0.5 mg/ml and 1.5 mg/ml to 2.0 mg/ml ranges, which indicated that not only an intermediate but also a weak drunkenness level could be a risk factor of being involved in forensic fatalities. There were no differences in mean ethanol concentrations in the blood samples of the right, left and whole heart blood collected from each victim. The femoral blood, however, was slightly higher than those of heart blood. N-Propanol, an indicator for postmortem ethanol production, was detected in 14.7% of stomach contents samples as early as 6 to 12 hours of post mortem intervals, whereas it was not remarkable in urine and femoral vein blood.
