Effects of nasal dilator strips on subjective measures of sleep in subjects with chronic nocturnal nasal congestion: a randomized, placebo-controlled trial.

ABSTRACT:

Background

This exploratory study investigated effects of a new asymmetric butterfly-shaped prototype nasal dilator strip and the currently marketed clear Breathe Right Nasal Strip (BRNS) on subjective measures of nasal congestion and sleep quality.

Methods

In this randomized, double-blind study, subjects with chronic nasal congestion and sleep difficulties were assigned a BRNS clear strip, an asymmetric butterfly prototype, or an asymmetric butterfly placebo strip without springs, to use nightly for 2 weeks. The main outcomes included change from baseline to days 7 and 14 on the Pittsburgh Insomnia Rating Scale (PIRS), Nocturnal Rhinoconjunctivitis Quality of Life Questionnaire (NRQLQ), and Congestion Quantifier Seven-Item Test (CQ7).
