A month ago, a 6-year-old child (pseudonym) was infected with H1N1 fever and his symptoms of runny nose did not improve. However, his parents did not take it to heart because they felt that the child did not have any other discomfort. Until recently, Tong Tong caught his mother's attention due to multiple nosebleeds and came to Nanjing Tongren Hospital for treatment. After the doctor inquired about the medical history and endoscopic examination, it was found that there was significant vasodilation and mucosal erosion in the front end of the child's nasal cavity. The preliminary diagnosis was that the child's nasal bleeding was caused by dry nasal scabs caused by excessive nasal mucus after acute rhinitis, which was often caused by digging the nostrils. "In addition to nosebleeds, there is also vestibular inflammation, which is two common hazards caused by frequent nostril digging, and such patients are also very common in outpatient clinics." Sun Chuan, Deputy Chief Physician of the Department of Otolaryngology and Head and Neck Surgery at Nanjing Tongren Hospital, introduced, "The lumps formed by substances such as mucus, shed skin cells, moisture, dust, and bacteria in the nasal cavity, or dry scabs formed by nasal mucus, can stimulate the local mucosa, causing discomfort in the nose. Firstly, it will make us feel itchy and unable to resist scratching." Sun Chuan explained that the capillaries in the nasal cavity are relatively rich, and places like the nasal cartilage area are shallow, with frequent and excessive digging of the nostrils Sharp nails, etc., may scratch blood vessels, leading to nosebleeds. "At this time, bacteria on the fingers and nails can easily enter the nostrils, causing infection and forming vestibular inflammation. Common symptoms include redness, swelling, pain, and even pus discharge from the nasal vestibule. In severe cases, bacteria may also directly invade the bloodstream from the wound, causing intracranial infections." Sun Chuan reminds that when nasal mucus and feces increase, You can consistently use physiological saline for nasal cleaning, ensuring at least 3-5 times a day. In addition, it is not recommended to use tools such as ear spoons, tweezers, cotton swabs, etc. to dig the nostrils and avoid hard objects scratching the nasal cavity.
