The study investigated the effect of saline nasal lavages on upper airway symptoms in COVID-19 patients who tested positive for SARS-CoV-2.
Participants performed daily nasal rinses for 12 days, reporting a 24.7% reduction in symptoms like blocked or runny nose compared to a control group.
Most users found the nasal lavages easy to use, with 90% satisfaction, but other symptoms like anosmia and infection duration showed no significant difference between groups, highlighting the need for further research.
Study examines nasal lavage as an alternative method for detecting SARS-CoV-2, aiming to address discomfort linked with traditional swabs.
Results from 49 positive subjects show that nasal lavage has a sensitivity of 97.7%, specificity of 100%, and accuracy of 98.9% when compared to standard swabs, with strong agreement in test outcomes.
Authors conclude that nasal lavages are reliable and better tolerated, suggesting further investigation with larger samples is needed to confirm efficacy as a substitute for nasopharyngeal swabs.
