BAC与腹肌酒精浓度的相关性:在严重损伤病例中有前途的降落伞基质
乙醇是全世界滥用最多的药物,也是对药物引起/相关死亡的毒理学分析中最常证明的药物之一。当以严重创伤为特征的死亡无法获得血液样本时,需要一个替代矩阵来估计损伤。提出了死后血液与腹直肌乙醇浓度的相关性。采用顶空气相色谱/质谱法测定血液和肌肉中的乙醇浓度。选取29例BAC阳性法医病例进行相关性研究。在所有选定病例中,死亡后的情况和时间都是已知的。肌肉分析表明,在0.03-0.9 mg /gmuscle范围内,分析响应呈线性关系。三种QC样品(0.15-0.3和0.6 ml /gmuscle)的定量可与基于基质的定量重叠。通过特异性、生物基质回收率(92.5%)、灵敏度(LOD为0.15 mgeethanol /gmuscle, LLOQ为0.03 mgeethanol /gmuscle)、定量分析偏差在3.5% ~ 6.1%之间进行了验证。采用方差分析f检验确定运行内和运行间精度,结果均小于20%。在选定的死后样本中,BAC与乙醇肌肉水平之间存在线性相关性,并将相关方程(y = 0,5837x + 0,0353; R²= 0,8661)用于无法获得血液的三个法医案例的BAC估计。腹直肌被证明是估计死亡时血液酒精浓度和损伤的良好候选者。

期刊介绍: Forensic Science, Medicine and Pathology encompasses all aspects of modern day forensics, equally applying to children or adults, either living or the deceased. This includes forensic science, medicine, nursing, and pathology, as well as toxicology, human identification, mass disasters/mass war graves, profiling, imaging, policing, wound assessment, sexual assault, anthropology, archeology, forensic search, entomology, botany, biology, veterinary pathology, and DNA. Forensic Science, Medicine, and Pathology presents a balance of forensic research and reviews from around the world to reflect modern advances through peer-reviewed papers, short communications, meeting proceedings and case reports.
