摘　　要：目的观察机械性窒息主要征象——瘀点性出血经过高温(烘烤、水煮)作用后的病理学特点及其变化规律。方法采用扼压颈部以及前位缢型缢死的方式建立家兔机械性窒息死亡动物模型,将处死的家兔随机分为烘烤组和水煮组,每组4只。对烘烤组家兔的喉室及心肺组织进行烘烤3 min、6 min、10 min后,对瘀点性出血部位进行观察并拍照。将水煮组家兔的喉室及心肺组织置于沸水(100℃)中加热,在30 s和60 s时观察并拍照。最后将所有实验家兔的喉室、双肺组织进行组织病理学检验。结果 8只家兔喉室、气管及肺组织瘀点性出血经高温作用后未消失,肉眼可见其颜色加深,与周围正常组织区别明显,易辨别,镜下亦可见出血。结论机械性窒息所致的瘀点性出血可能与致伤方式、作用力度、作用时间以及个体差异有关,在高温作用后不会消失。Objective To study the main features of mechanical asphyxia--the pathological characteristics of petechial hemorrhage after high temperature effect(roasted,boiled)and its changing rules.Methods Rabbit model of mechanical asphyxia death with choking neck and death from anteposition hanging was established.The experimental rabbits were randomly divided into roasted group and boiled group(n=4,in each group).The laryngeal ventricles and cardiopulmonary tissues in the roasted group were roasted for 3,6 and 10 min,and the positions of petechial hemorrhage were observed and photographed.The same organs and tissues in the boiled group were heated in boiling water(100℃),and were observed and photographed at 30 and 60 s.Then histopathological examination was performed on all the laryngeal ventricles and cardiopulmonary tissues.Results The petechial hemorrhage originating from laryngeal ventricle,trachea and lung did not disappear after high temperature treatment in the eight rabbits.The deepened color was visible to naked eyes and distinct from the surrounding normal tissues,with bleeding under the microscope.Conclusion Petechial hemorrhage caused by mechanical asphyxia would not disappear under high temperature,which might be related to the manner of death,the intensity and time of action,and the individual differences.
