The symptoms and signs score, treatment index and total effective rate were evaluated before and after treatment, and the nasal conjunctivitis related quality of life questionnaire (BQLQ) was used to evaluate the life quality of patients.There were significant differences of the symptoms, signs scores, the treatment index, the total efficiency and BQLQ between the two kinds of lavage fluid used for patients before and after treatment(<0.05). No significant adverse reactions occurred during follow-up.Hydrogen-enriched saline is safe and effective for allergic rhinitis.
