The role of rhino bronchial reflex in bronchospasm in patient with allergic rhinitis and bronchial asthma.
Abstract
Introduction:The nasal cavity is the main entrance for air to the lungs, and therefore the upper and lower respiratory tracts are closely related to each other. This is what prompted us to study this reflexive functional relationship between the nose and bronchi and prove it through this study.
Patients and methods :The study included 75 patients who attended the ear clinic with a history of allergic rhinitis or patients who had asthma symptoms but were not diagnosed with asthma in July 2020 and July 2021 AD at Tishreen University Hospital in Lattakia. Where a complete clinical history of the patient was taken, then a measurement of the patient's lung function was done before provocation of the nasal mucosa or scratching it with a cotton holder, and after provocation the lung function was re-measured
Results :A decrease in lung function values after nasal mucosal irritation or provocation was observed in the majority of patients, with statistically significant differences (P>0.001) for all lung function tests, as all values decreased compared to the values before nasal mucosal irritation.
Conclusions:There is an important reflexive functional relationship between the upper respiratory tracts and the lower respiratory tracts
