春季尸体腹腔腐败气压在法医学死亡时间推断中的应用研究

The development and changes of pressure of putrefactive gas in cadaveric enterocelia in spring and its forensic application

目的 研究尸体腹腔腐败气压在春季的发展变化规律及其用于推断死后经过时间的方法。方法用实验动物山羊57只,分陆地处死和水中溺死两大组,用自行研制的“腐败气压测定仪”,定时系统测量动物尸体腹腔内的腐败气压。结果 得出尸体腹腔内腐败气压的发展变化规律,并据此建立测量腹腔腐败气压推断死后经过时间的方法。研究了数种死亡方式、尸体所处环境和个体差异等的影响。结论 该研究成果填补了法医学中尸体腐败气压发展变化规律研究、检测腐败气压推算死后经过时间和腐败气压测定仪等的多项空白,丰富了该领域的法医学内容。

Objective To study the development and changes of pressure of putrefactive gas (PPG) in cadaveric enterocelia in spring,and to explore its application in estimation of postmortem interval (EPI). Methods 57 goats were divided into 2 groups according to means of death,on land or in water. Celiac PPG were observed timely and systematically. Results The development of PPG in cadaveric enterocelia,which can be divided into raising phase,peak phase,and declining phase was observed,and a model to estimate postmortem interval by changes of PPG was founded. Conclusion Measuring PPG in cadaveric enterocelia could be used in forensic EPI.
