If a patient has a nosebleed, it may flow down the throat and cause bloody sputum, which is normal. Because the nasal cavity and the pharyngeal cavity are connected, if the bleeding volume is relatively large, it will lead to the patient’s throat spitting bloody phlegm. The main treatment is to stop the nosebleed, you can apply recombinant human epidermal growth factor gel inside the nose, or use a swelling sponge to fill in. Electrocoagulation can be used to stop the bleeding effectively and quickly by directly coagulating the bleeding area. When the nosebleed is relieved, the patient’s spitting of bloody phlegm inside the throat will also improve significantly. In life, patients should pay attention to the protection of the nose, try not to be hit by external forces, and do not use the hand to dig the nostrils, so as not to cause the blood vessels or mucous membrane inside the nasal cavity rupture, resulting in bleeding.
