0.9% sodium chloride solution (also known as saline) is an isotonic solution that does not cause irritation to the nasal mucosa. Rinsing the nasal cavity can keep the nasal cavity clean and moist, flush out the mucous and purulent secretions as well as bacteria and allergens in the nasal cavity, and keep the nasal mucosa in a clean and healthy state.
When using 0.9% sodium chloride injection to flush the nasal cavity, special attention should be paid to the strength and frequency, frequent excessive rinsing is easy to destroy the normal microenvironment in the nasal cavity, resulting in weakening of the local immune system, while too much strength will wash the secretions or bacteria to the vicinity of the Eustachian tube, increasing the risk of secondary otitis media.
