Abstract

Objective: To compare the accuracy of determining the postmortem interval using the best methods of single and dynamic thermometry of a corpse in the presence of metrological errors and to find ways to increase it for methods of dynamic thermometry of a corpse.

Material and methods: A controlled comparative analysis of errors in determining the postmortem interval using C. Henssge methods and nonlinear programming was performed for one- and two-hour time intervals between measurements of cadaver temperature. The database of G.S.W. De Saram and co-authors, which contained data from 37 observations of standardized dynamic rectal thermometry, was used as research objects.

Results: The results of determining the postmortem interval by dynamic postmortem thermometry due to an increase in the number of temperature measurements are more susceptible to the negative influence of metrological errors than estimates of methods based on single thermometry of a corpse. It is possible to increase the accuracy of dynamic thermometry methods by reducing body temperature measurement errors, increasing the time interval between them and reducing their number.

Conclusions: The results of determining the postmortem interval by postmortem dynamic thermometry due to an increase in the number of temperature measurements are more susceptible to the negative influence of metrological errors than estimates of methods based on single thermometry of a corpse. It is possible to increase the accuracy of dynamic thermometry methods by reducing body temperature measurement errors, increasing the time interval between them and reducing their number.

[通过对尸体进行单次和动态测温来确定死后时间间隔的准确性对比分析]。

目的：比较在存在计量误差的情况下，最佳尸体单次测温法与动态测温法测定死后时间间隔的准确性，并探讨如何提高动态测温法测定死后时间间隔的准确性。材料和方法：采用C. Henssge方法和非线性规划对尸体温度测量间隔一小时和两小时的误差进行对照比较分析。G.S.W. De Saram及其合著者的数据库包含了37项标准化动态直肠测温的观测数据，作为研究对象。结果：由于测温次数的增加，动态测温法确定死后间隔的结果比单次测温法估计的结果更容易受到计量误差的负面影响。可以通过减小体温测量误差、增加误差之间的时间间隔和减少误差的次数来提高动态测温方法的精度。结论：由于温度测量次数的增加，通过尸体动态测温来确定死后时间间隔的结果比基于单一尸体测温方法的估计更容易受到计量误差的负面影响。可以通过减小体温测量误差、增加误差之间的时间间隔和减少误差的次数来提高动态测温方法的精度。
