H2-Rich Saline for Allergic RhinitisScientific Research
original title: Changes of nasal nitric oxide in the treatment of allergic rhinitis with hydrogen-rich saline lavage of nasal cavityDOI: 10.13201/j.issn.2096-7993.2020.03.014
Objective:To observe the effect of hydrogen-rich saline on the concentration of nitric oxide in the nose, and to explore the mechanism of its treatment of allergic rhinitis. Method:Twenty patients with moderate to severe persistent allergic rhinitis were enrolled in a randomized, double-blind, self-controlled study. The nasal cavity was lavaged with hydrogen-rich normal saline and normal saline, and the nasal nitric oxide（nNO） value was tested weekly. Result:The test value of nNO was correlated with the diagnosis and curative effect of allergic rhinitis. The difference of nNO test values before and after treatment of the two lavage fluids was statistically significant（P<0.01）.
Conclusion:Hydrogen-rich saline lavage can cause nNO change in nasal cavity which may be used in the treatment of allergic rhinitis.
