The 3 principles of treatment for nosebleeds are: 1. To stop the bleeding immediately, generally the site of nosebleeds lies in the bleeding-prone area at the front of the nasal septum, so anterior nostril stuffing can be done. If you can see the bleeding point, or if there is a hemangioma, you can do nasal electrocoagulation to stop the bleeding.2. To maintain vital signs and prevent acute haemorrhagic shock, actively resuscitate haemorrhagic shock, replenish blood volume and maintain vital signs.3. Only then can the nosebleed be completely treated.
