To assess the influence of anaerobic bacterial heat production in human stools as a confounding factor in postmortem rectal temperature measurements, in vitro experiments were carried out with human stools incubated at 37 degrees C for 6 h and at decreasing temperatures simulating a postmortem body cooling. Although a statistical significant heat production was observed, it was not relevant enough to explain a postmortem temperature plateau or a substantial rise in the postmortem body temperature. The experiments suggest that stools merely reflect the environmental thermal changes rather than producing bias and confounding by a bacterial heat production.
为评估人体粪便中厌氧细菌产热作为死后直肠温度测量中的一个混杂因素的影响，进行了体外实验，将人体粪便在37℃下孵育6小时，并在模拟死后尸体冷却的降温条件下进行实验。尽管观察到有统计学意义的产热，但这一产热不足以解释死后体温平台期或死后体温的大幅上升。实验表明，粪便仅仅反映了环境温度变化，而不会因细菌产热产生偏差和混杂影响。
