At home, the child was treated with antibiotics and anti-flu medication, and his symptoms improved slightly when the medication was used, but recurred after the medication was stopped. Nasal endoscopy was performed firstly after the consultation, and it showed that the mucosa of the nasal cavity and the inferior turbinate were pale and edematous, the nasal septum was roughly centered, and the edematous inferior turbinate was in contact with the septum, and a large amount of clear watery nasal mucus was adhered to the nasal cavity, and no new organisms had grown in the nasal cavity after the suction device was cleaned up. Allergen testing showed a marked increase in total serum IgE, and the child was allergic to pollen (++++) and dust mites (+++). Through the child’s medical history and examination, the final diagnosis was pediatric allergic rhinitis. After communicating with the parents of the child, the following treatment plan was formulated for the child, and the family expressed their understanding and willingness to cooperate with this treatment plan. 1, first of all, we need to avoid contact with pollen, dust mites and other known contact allergens, regular cleaning of bedding, to avoid the peak of allergy pollen dispersal, in order to reduce the onset of symptoms; 2, with physiological sea saline cleaning nasal cavity, the nasal cavity of the clear water slugs rinsed thoroughly, can reduce nasal congestion, dilute nasal secretions, thus improving the sense of smell; 3, nasal spray with anti-allergic rhinitis drugs (budesonide nasal spray), and oral anti-allergy drugs (budesonide nasal spray), as well as the use of oral antiallergic drugs (oral antiallergic drugs), the family is willing to cooperate with this treatment plan. At the same time, oral anti-allergic drugs (levocetirizine hydrochloride oral drops). After regular medication and lifestyle improvement, the child came to our department for follow-up in half a month, complaining of itchy nose, nasal congestion, runny nose, headache and other related symptoms, which were obviously improved, and there was no more open-mouth breathing and waking up, and the quality of sleep was greatly improved. Nasal endoscopy revealed that the nasal mucosa no longer had obvious mucosal pallor and edema. The patient resumed his normal life condition and his quality of life was significantly improved. IV.
