In brief Epistaxis typically originates from the nasal septum when the nasal mucosa overlying a dilated blood vessel is injured. Epistaxis may, however, signal an underlying condition such as a coagulation disorder, so the treating physician must be alert for signs of serious illness. Most nosebleeds stop spontaneously within 5 minutes with or without pressure to the forehead, nose, or upper lip. Some require anterior nasal packing. A few arise from posterior arteries and require anterior-posterior nasal packing and a referral.
简而言之,鼻出血通常起源于鼻中隔,即覆盖扩张血管的鼻黏膜受伤时。然而,鼻出血可能预示着潜在疾病,如凝血障碍,因此治疗医生必须警惕严重疾病的迹象。大多数鼻出血在5分钟内会自行停止,无论是否对前额、鼻子或上唇施加压力。有些鼻出血需要进行前鼻孔填塞。少数鼻出血起源于后鼻孔动脉,需要进行前后鼻孔填塞并转诊。
