Frequency of symptoms. At 8 weeks, 40% of the irrigation group and 61% of the nasal spray group reported nasal or sinus symptoms “often or always.” The absolute risk reduction in symptom frequency with saline irrigations, therefore, was 0.21; 95% confidence interval, 0.02-0.38 (P=.01). The odds of frequent nasal symptoms were 50% lower in the irrigation group compared to the spray group.

WHAT’S NEW: One delivery method is better than another

Prior studies had proven the effectiveness of nasal saline for reduction of rhinosinusitis symptoms. This RCT demonstrated that large-volume, low-pressure nasal irrigation brings greater symptom relief than nasal spray.

The researchers found little difference between the 2 groups in the rate of adverse effects, and reported that nasal irrigation appears to be well accepted once patients become accustomed to it. The fact that the participants were recruited from the general population further suggests that the results will be generalizable to primary care patients.

CAVEATS: High dropout rate in irrigation group

The absence of a control group prevents us from knowing the effect of saline nasal spray or irrigation compared with no treatment. In prior studies, however, nasal saline spray was found to be more effective than placebo in reducing rhinosinusitis symptoms.^8,15

FAST TRACK

Large-volume, low-pressure nasal irrigation brings greater symptom relief than nasal spray for rhinosinusitis symptoms

It is notable that a significant portion (21%) of the irrigation group abandoned this treatment by 8 weeks; in comparison, just 7% of the nasal spray group discontinued treatment.

This lower rate of adherence makes the beneficial effects of the irrigation group even more impressive. But it also suggests that a significant portion of patients are unlikely to stay with this recommended regimen. For those who try saline irrigation and choose not to continue it or are unwilling even to try it, saline spray is a reasonable alternative.

It should be noted that financial support for this study was provided by NeilMed Pharmaceuticals, a manufacturer of nasal saline solution and irrigation devices. However, the sponsor was not involved in the design or conduct of the study, in data collection or analysis, or in the preparation of the manuscript.
