膈肌疲劳在家兔体位窒息死亡中的作用

The Role of Diaphgram Fatigue in the Death from Hanging with Bound upper Limbs of Rabbits

目的探讨膈肌在固定双上肢悬挂致死中的作用。方法将家兔固定双上肢悬挂,并监测家兔膈肌肌电图(EMGdi)的变化。结果在连续记录的EMGdi中早期的EMGdi与晚期的EMGdi比较高频与低频(H/L)的比值显著降低,提示膈肌疲劳确实存在。结论膈肌疲劳在固定双上肢悬挂致死中起着重要的作用。

Objective To explore the role of diaphgram fatigue in the death from hanging with bound upper limbs of rabbits. Methods Rabbits were hanged with upper limbs bound, then the data of EMGdi. were gathered Results By analyzing power spectral of EMGdi in experiment, we compare the ratio change of H/L between pre-experiment and post-experiment. There is a significance decrease of the ratio of H/L, so it indicates that diaphgram fatigue does exist. Conclusion Diaphgram fatigue plays an important role in the death from hanging with limbs of rabbits bound.
