对一般情况而言,鼻出血只不过是“小菜一碟”,并非大病。但高血压患者倘若发生鼻出血,将有65％的人在半年内发生中风。这是老年医学专家经过大量研究后得出的结论。 人到老年,体内大小血管都不同程度的硬化,鼻腔内的血管尤为显著。加上鼻粘膜较为薄弱,又常受寒冷、炎热、干燥、外伤及致病微生物的侵袭,血管易受损伤破裂。当血压升高而颅内血管未破裂之前,鼻腔内的血管往往先期破裂,成为中风先兆。如兼患慢性支气管炎、支气管扩张、肺气肿、肝硬化、血液病及尿毒症时,则发生鼻出血的可能性更大,出血量也更多,且不易止血。 一旦发生鼻出血,首先要保持镇静,以免因精神紧张使血压继续升高,加剧出血。头勿后仰,以免血液呛入气管而出现窒息危险;速
In the general case, the nosebleed is only a piece of cake, not a serious illness. However, in the event of epistaxis in hypertensive patients, 65% of people will have a stroke within six months. This is the result of extensive research conducted by geriatricians. People to the elderly, the body size of the blood vessels are hardened to varying degrees, the blood vessels within the nasal cavity is particularly significant. Coupled with the nasal mucosa is relatively weak, but also often cold, hot, dry, traumatic and pathogenic microorganisms invasion, vascular vulnerability to rupture. When the blood pressure and intracranial blood vessels did not rupture before the nasal often premature rupture of blood vessels, a sign of stroke. Such as suffering from chronic bronchitis, bronchiectasis, emphysema, cirrhosis, hematology and uremia, the greater the possibility of epistaxis, bleeding more, and not easy to stop bleeding. In the event of nasal hemorrhage, we must first remain calm, so as to avoid mental stress so that blood pressure continues to rise, exacerbating bleeding. Do not lean back, so as not to choke the blood into the trachea and choking hazard; speed
