项目摘要

We performed automatic continuous monitoring of rectal and ambient temperatures using button-type thermo data loggers in autopsy cases. The button-type data loggers (SEC-CD16TB, Sanyo) have a battery-powered memory that can record 2048 temperature readings. The measurement intervals and other initial settings are determined by computer software, and the measurements were taken at 5-minute intervals for this study. At autopsy, the data loggers were retrieved and recorded temperature graphs were produced. In the Miyagi prefecture, this method has been used since July 2004. For 21 months, 152 cases were monitored from 375 autopsies, and 103 were available. We estimated the postmortem interval (time of death) using monitoring results in many cases. In one case, the button-type data logger was not discharged regardless of how the body was moved after the device was inserted into the rectum. In two other cases, the cooling curves of the rectal temperature readings clearly followed changes in ambient cooling conditions. The advantages of the tested devices are their small size (diameter, 17.4 mm; thickness, 5.9 mm) and ease of insertion into the rectum, requiring no special skills. Many temperature-based algorithms to determine time of death have been developed, and as a matter of course, the temperature values must be accurate and reliable. Ensuring the validity of each temperature reading requires continuous data from an internal data logger. Even if a two exponential formula is used, the extraction from these sequence data is recommended to get more reliable estimation. Button-type data loggers are suitable for this purpose, and this study demonstrates their application in practical cases. We present application to help introduce this method to other areas.

我们进行了自动连续监测直肠和环境温度使用按钮型热数据记录仪在尸检病例。按钮式数据记录仪（SEC-CD 16 TB，Sanyo）有一个电池供电的存储器，可以记录2048个温度读数。通过计算机软件确定测量间隔和其他初始设置，并且对于本研究，以5分钟间隔进行测量。在尸检时，取回数据记录器并生成记录的温度图。宫城县自2004年7月以来一直采用这种方法。在21个月的时间里，从375例尸检中监测了152例病例，其中103例可用。我们在许多情况下使用监测结果估计死后间隔（死亡时间）。在一个病例中，按钮型数据记录器在插入直肠后，无论身体如何移动，都不会放电。在另外两种情况下，直肠温度读数的冷却曲线清楚地跟随环境冷却条件的变化。测试装置的优点是尺寸小（直径17.4 mm;厚度5.9 mm），易于插入直肠，不需要特殊技能。已经开发了许多基于温度的算法来确定死亡时间，当然，温度值必须准确可靠。确保每个温度阅读的有效性需要来自内部数据记录器的连续数据。即使使用双指数公式，也建议从这些序列数据中提取以获得更可靠的估计。按钮型数据记录器适合于此目的，本研究展示了它们在实际案例中的应用。我们提出的应用程序，以帮助介绍这种方法到其他领域。
