A Case of Forensic Pathology Identification of Choking
Choking is asphyxial death caused by a foreign body blocking the respiratory tract from the inside and obstructing the exchange of gas.In forensic pathology identification,choking is rare,and its identification is mainly based on the discovery of foreign bodies in the throat,trachea,bronchus and other parts of the deceased during autopsy,which can be food,such as lumps,or non-food.There have been previous reports of cases of choking caused by mistakenly swallowing balloons.The similarity with this case is that foreign bodies may have one-way valve effect,but the difference is that the parts of the foreign bodies obstructing the airway are different.The foreign body in this case was dried glutinous rice cake,which was mainly dry and hard,and the total amount of foreign bodies in the airway was large,which completely blocked the left and right main bronchus and caused the asphyxial death.The identification opinion of choking death must go through a systematic autopsy,exclude other causes of death,and make a comprehensive analysis and judgment in combination with the case,so as to diagnose the cause of death.The vast majority of choking deaths are accidental.This paper systematically summarized a case of accidental choking,sorted out the pathological features and points of identification with other causes of death,hoping to provide valuable reference for forensic colleagues.
