摘要

估计死后间隔时间(PMI)主要基于尸体冷却状态、死后生动(livor mortis)和死后肌肉僵硬(rigor mortis)。然而,这些死后现象的发展时间跨度受到与死者尸体和尸体发现环境有关的各种因素的影响。因此,在确定这些现象的状态时,PMI 的上限和下限会有很大差异。此外,对尸斑、尸僵等死后现象的解释以及对亨斯格名义图校正系数的解释都是主观的。因此,对 PMI 的估计往往过于宽泛,可能无助于回答与刑事调查有关的问题。因此,建议结合不同方法的结果来估计 PMI,即所谓的复合方法。通过对骨骼肌的机械刺激产生的眶上肌反应是复合法中一个鲜为人知的方面。在此,我们介绍了一系列案例,在这些案例中,肌肉上皮反应有助于更精确地估计 PMI。

Estimation of the post-mortem interval; added value of mechanical excitability of human skeletal muscle

Estimation of the post-mortem interval (PMI) is mainly based on the state of body cooling, post-mortem lividity (livor mortis) and post-mortem muscle stiffness (rigor mortis). However, the time span of development of these post-mortem phenomena are influenced by a variety of factors concerning the body of the deceased and the environment in which the body is found. Subsequently, this leads to a substantial spread in upper and lower limits of PMI based on determination of the state of these phenomena. Moreover, interpretation of post-mortem phenomena like lividity, rigor and interpretation of the correction factor for Henssge's nomogram is subjective. For this reason, PMI estimations are often broad, possibly too broad to be helpful for answering questions which are relevant for the criminal investigation. Therefore, combining the outcome of different methods for estimating the PMI, the so-called compound method, is recommended. Supravital muscle reaction by mechanical stimulation of skeletal muscle is a less known aspect of the compound method. Here we present a series of cases series in which supravital muscle reaction contributed to a more precise estimation of the PMI.
