Blood alcohol (ethanol) concentrations in decomposed bodies can mean drinking during life and/or endogenous production after death. The correct interpretation is important in medicolegal cases. This retrospective study of 286 autopsied medical examiner cases was undertaken to evaluate alcohol concentrations and distribution in various fluids and tissues in decomposed bodies. Cases with alcohol present were classified as endogenous production, ingestion, or unable to determine based upon one or more of the following criteria: the presence of ethanol in only one of more than one body fluids, an atypical distribution of ethanol in body fluids, reliable scene or historical information, the presence of C3 alcohols in body fluids. Alcohol was classified as endogenously produced in 55 cases. The presence of alcohol was attributed to ingestion in 130 cases. No alcohol was detected in 39 cases. We were unable to determine the source of the remaining 62 alcohol concentrations. The highest blood alcohol concentration derived from endogenous production was 0.07% in the cases with other fluids negative. The mean blood alcohol concentration was 0.06% and ranged as high as 0.16% in cases having atypical ratios. Alcohol was found in blood and bile while urine and vitreous fluid were negative or had lower concentrations in cases with endogenous production. We conclude that for the majority of cases in which endogenous blood production of alcohol occurs the concentration in blood may be as high as 0.15%.
腐败尸体中的血液酒精（乙醇）浓度可能意味着生前饮酒和/或死后内源性生成。在法医学案件中，正确解读这一结果很重要。本研究对286例法医尸检病例进行了回顾性分析，以评估腐败尸体中各种体液和组织中的酒精浓度及分布情况。根据以下一项或多项标准，将检测到酒精的病例分为内源性生成、摄入或无法确定：仅在一种以上体液中检测到乙醇、乙醇在体液中的分布不典型、有可靠的现场或病史信息、体液中存在C3醇。55例病例的酒精被归类为内源性生成。130例病例中酒精的存在归因于摄入。39例未检测到酒精。其余62例酒精浓度的来源我们无法确定。在其他体液呈阴性的病例中，内源性生成的最高血液酒精浓度为0.07%。非典型比例病例的平均血液酒精浓度为0.06%，最高可达0.16%。在内源性生成的病例中，血液和胆汁中发现了酒精，而尿液和玻璃体液呈阴性或浓度较低。我们得出结论，对于大多数发生酒精内源性血液生成的病例，血液中的浓度可能高达0.15%。
