摘要
目的:研究扼颈窒息死亡的血液生化学变化,探讨血气分析和K+,Cl-的检验对鉴定扼死的法医学意义. 方法:将家兔用扼颈的方法处死,进行血气分析和K+,Cl-的测定. 结果:扼死家兔血中pH值下降(P<0.005),PCO2增高(P<0.01),PO2降低(P<0.05),O2SAT下降(P<0.01),HCO3-增加(P<0.005),TCO2增加(P<0.05),BE变化不明显.静脉血中K+浓度明显增高(P<0.01),Cl-浓度变化不明显. 结论:扼死家兔血气分析和K+浓度发生明显变化,检验血气分析和K+,Cl-浓度对鉴定扼死具有法医学意义.
Abstract
AIM: To study the biochemistry change in blood and the significance for forensic medicine to measure the consistency of K+ and Cl- in venous blood and analysis of the gases in blood by manual strangulation. METHODS: The rabbits were put to death by manual strangulation and the gases in blood and the consistency of K+ and Cl- in venous blood were measured respectively. RESULTS: The pH dropped (P ＜ 0.005). The PCO2 was increased (P ＜ 0.01). The PO2 decreased (P ＜ 0.01). The O2SAT also reduced (P ＜ 0.01). The HCO3- increased (P ＜ 0.05), and so was the TCO2 (P ＜ 0.05), the concentration of K+ rose remarkably (P ＜ 0.01). The change of Cl- was not evident. CONCLUSION: The change on the biochemistry in blood for rabbits were obvious. There are significance for forensic medicine to measure the consistency of K+ and Cl- in venous blood and analysis of the gases in blood.
