作者对91个习惯性鼻衄患者进行疾病筛选。所有患者在过去二年里每年至少鼻出血4次,69%一年中超过12次。检查前10天患者停用水杨酸类药物。筛选试验包括:血小板计数、出血时间(IVY 氏法)、活化部分凝血活酶时间(APTT)、凝血酶原时间、纤维蛋白原、凝血时间、纤维蛋白(原)降解产物、凝血因子Ⅷ促凝活性(Ⅷ:C)种毛细血管脆性试验。如果筛选试验异常,再检查是否有止血 The author of 91 patients with habitual nose disease screening. All patients had at least 4 episodes of epistaxis each year over the past two years, and 69% had over 12 episodes a year. Patients stopped using salicylate 10 days prior to the exam. Screening tests include platelet count, bleeding time (IVY’s method), activated partial thromboplastin time (APTT), prothrombin time, fibrinogen, clotting time, fibrin (prot) degradation products, coagulation factor VIII procoagulant Activity (Ⅷ: C) Capillary fragility test. If the screening test is abnormal, check if there is any hemostasis
