Aspiration of food or liquids can result in suffocation, evolving in coughing, difficulty breathing and forced exhalation. Asphyxia occurs when the aspirated material occludes the upper airways, either in the proximal or distal tract, resulting in the inability to breathe. The risk of asphyxiation death, is increased if a person makes sudden movements while eating, walks or runs while eating, or even becomes distracted or frightened. It is higher in individuals with neurological diseases, intellectual disability (ID), cognitive impairment, psychiatric pathologies or their pharmacological treatments and people carrying additional physiological impairments, which can cause oral dysfunction and dysphagia. Protective mechanisms may sometimes lack or fail to expel food fragments stuck in the airways, which completely obstruct them.
The authors present some peculiar cases of subjects who died from food bolus choking, namely a case of mozzarella-cheese clogging in a young subject (25 years old) undergoing rehabilitation treatment following a stroke; a 38-year-old man with middle-grade mental retardation died from first airway food bolus (mush of bread) clogging; a 26-year-old subject with epilepsy died from tripe clogging in the course of a seizure; a 38-year-old subject in psychiatric treatment for depressive disorder who died from clogging with octopus tentacles.
Food bolus clogging asphyctic deaths generally occur in subjects with psychic/neurological pathologies, resulting in altered deglutition mechanisms or lack of protective reflexes. Foodstuff, especially if large or viscous, obstruct the proximal or distal airways, leading to acute respiratory failure and death. Autopsy is diriment in ascertain the cause of death.
食物或液体的吸入会导致窒息,表现为咳嗽、呼吸困难和被迫呼气。当吸入的物质阻塞上呼吸道时,会发生窒息,无论是在近端还是远端气道,导致无法呼吸。如果一个人在进食时突然移动、边吃边走或跑,甚至分心或受到惊吓,窒息死亡的风险会增加。患有神经疾病、智力障碍(ID)、认知障碍、精神病理学或其药物治疗以及存在其他生理障碍的个体,如口腔功能障碍和吞咽困难,风险更高。保护机制有时可能会缺乏或无法排出卡在气道中的食物碎片,从而完全阻塞气道。
作者介绍了一些因食物团块窒息而死亡的特殊病例,即一名年轻患者(25 岁)在中风后接受康复治疗时因马苏里拉奶酪堵塞;一名 38 岁中度智力障碍男子因第一气道食物团块(面包糊)堵塞而死亡;一名 26 岁癫痫患者在癫痫发作时因牛肚堵塞而死亡;一名 38 岁因抑郁障碍接受精神科治疗的患者因章鱼触手堵塞而死亡。
食物团块窒息性死亡通常发生在患有精神/神经病理学的患者中,导致吞咽机制改变或缺乏保护反射。食物,尤其是大块或粘性食物,会阻塞近端或远端气道,导致急性呼吸衰竭和死亡。尸检对于确定死因至关重要。
