单纯不同温度干热气体导致犬喉部不同部位组织烧伤后病理变化
发布时间:2018-10-26 16:19
【摘要】:目的:对不同温度干热气体导致犬喉部不同部位组织烧伤后的病理变化进行分析,并与临床分型进行对比分析。方法:用18只成年公犬建立动物模型,吸入80℃、160℃和320℃的干热气体,吸入时间为20 min,然后取会厌、喉前庭、声襞、气管的不同部位组织进行病理学观察。结果:80℃组的组织病理主要表现为局部黏膜萎缩样改变,160℃组以喉部黏膜下组织的中度水肿变化为主,320℃组有重度水肿型及萎缩硬化型两种病理改变。结论:喉部由于其特殊的解剖和功能,对不同温度的热气损伤反应不一,通过病理学上的观察和分析可以看出,80℃组、160℃组的喉烧伤的病理改变基本符合充血型及水肿型的喉镜表现,而320℃组却有重度水肿型及萎缩硬化型两种不同的病理改变,故喉烧伤的病理学分析作为临床分型的补充有着重要意义。
