Efficacy and Variations of Nasal Irrigation as a Home Treatment for Allergic Rhinitis in Pediatric Populations

This project is a scoping review that aims to map the extent, characteristics, and nature of the available evidence on nasal irrigation as a home-based treatment for allergic rhinitis in pediatric populations. The review will be conducted in accordance with the JBI methodology for scoping reviews. It will consider studies involving children aged 2–18 years diagnosed with allergic rhinitis and will focus on variations in nasal irrigation methods, including saline solution type, delivery systems, dosage, frequency, and duration, as well as reported clinical outcomes, safety, and tolerability. A comprehensive literature search will be conducted in MEDLINE (PubMed), EMBASE, CINAHL, and CENTRAL. Eligible sources of evidence will include experimental, observational, qualitative studies, and systematic reviews published in peer-reviewed journals. Study selection and data extraction will be performed independently by two reviewers, with results presented using tabular mapping and narrative synthesis. The purpose of this scoping review is to provide an overview of how nasal irrigation has been studied and applied in pediatric allergic rhinitis and to identify gaps in the existing literature to inform future research.
