In the case of nasal bleeding, patients are advised to keep their heads low, not to tilt their heads, and they need to relax and not to panic. They can use their own hands to compress the nasal flank, which has a better effect on stopping the bleeding at the front of the nasal cavity. Patients need to go to the ENT department as soon as possible. After the consultation, routine blood and coagulation tests can be done to determine whether there is a blood disorder. If there is a blood disorder, symptomatic treatment is needed and a nasal endoscopy is required. The purpose of the nasal endoscopy is to clarify the specific bleeding point inside the nasal cavity. Many patients can use hemostatic materials to fill the nasal cavity to stop bleeding by compression, but there are some patients with large bleeding or hidden bleeding location, the effect of simple filling to stop bleeding by compression is not good, in this case, it is necessary to consider nasal endoscopic surgery to explore and stop bleeding.
