Background/Aims:
Nasal saline irrigation is a common procedure to relieve nasal symptoms in upper respiratory tract diseases. There is no consensus on the recommended nasal saline delivery devices. The objectives of this study were to evaluate efficacy, satisfaction, adherence, and adverse effects in patients with acute upper respiratory tract diseases using a syringe with a nasal applicator for nasal irrigation.
Methods:
Patients with acute nasopharyngitis, acute rhinitis, or acute rhinosinusitis were randomly allocated to use either (1) a syringe with a nasal applicator or (2) a syringe alone to irrigate one nostril. After the patients had completed irrigation with the allocated device in one nostril, they were instructed to perform nasal irrigation using the other device in the other nostril. All patients were instructed to use a syringe with a nasal applicator at home. The efficacy, satisfaction scores, adherence, and adverse effects were recorded.
Results:
Sixty-four patients were enrolled. The mean age of the patients was 33.95 years (18-59 years). The mean duration of symptoms was 4.80 days. None of the enrolled patients regularly performed nasal irrigation. Forty-two had acute nasopharyngitis, 10 had acute rhinitis, and 12 had acute rhinosinusitis. At baseline, the mean overall efficacy score for the syringe with a nasal applicator was 8.17 ± 1.43, and that for the syringe alone was 5.95 ± 2.02 (MD 2.23, p < 0.001, 95% CI 1.75-2.70). At 1 week, the syringe with the nasal applicator had significantly higher scores in 3 of 4 domains, including symptom relief, ease of use, and patients' willingness to recommend the device to others, compared to baseline (p < 0.05). None of the enrolled patients had epistaxis, retained/dislodged the applicator during irrigation, or experienced an allergic reaction to the applicator after 1 week of nasal irrigation.
Conclusion:
Use of a syringe with an applicator for nasal irrigation yielded high scores in overall efficacy.
