A preliminary histomorphological examination of the nasal mucosa of 8 heatstroke patients who presented without epistaxis, showed stromal vascular damage and degenerative changes in the basal lamina of the overlying epithelium, severe enough in two cases to indicate impending epistaxis, even in the absence of disseminated intravascular coagulation (DIC). It is suggested that direct damage by the extreme heat to mucosal structures, especially the prominent, thin-walled blood vessels, plays an important role in the genesis of epistaxis in heatstroke even in the absence of DIC.
对8例无鼻出血症状的中暑患者鼻黏膜进行的初步组织形态学检查显示，基质血管受损，上皮层基底膜出现退行性变化，其中2例变化严重，即使在没有弥散性血管内凝血（DIC）的情况下，也预示即将发生鼻出血。研究表明，即使在没有DIC的情况下，酷热对黏膜结构，尤其是突出的薄壁血管的直接损伤，在中暑鼻出血的发生中也起重要作用。
