Most nasal electrocoagulation is required for hospitalization. Nasal electrocoagulation is the use of bipolar electrocoagulation or an electric knife to stop bleeding from ruptured blood vessels in the nasal cavity. Both bipolar electrocoagulation and electrodebrider are disposable medical supplies, and for some of the blood vessels that are easily found in the anterior part of the nasal cavity, they can be performed on an outpatient basis if the patient can cooperate well. However, for most deep nasal vascular bleeding or persistent nasal bleeding, usually in the fornix of the inferior nasal tract or the olfactory fissure of the nasal septum, repeated examination by nasal endoscopy under general anesthesia is required to identify and clarify the responsible vessels and then to stop the bleeding by electrocoagulation. Therefore, most of the nasal hemorrhages need to be treated by hospitalization.
