The impact of proper aspiration of nasal secretions during upper respiratory infection on the frequency and severity of symptoms of lower airways has never been investigated. The study was aimed at testing if cleaning the nasal cavities of children with recurrent wheezing using an automatic nasal aspirator improves the upper and lower respiratory symptoms during the cold season. Methods: Parents of wheezing children (age 3-72 mo.) answered questionnaires and learned using a nebulizer equipped

During a 90-days monitoring period parents filled an electronic diary (BreathMonitor, TPS, Rome, Italy) on their child's symptoms of the upper and lower airways. Results: Eighty-nine/91 patients (43 cases, 46 controls) completed the study. Less days with upper (25.0% vs 46.4%, p = 0.004) or lower (21.8% vs 32.8%, p = 0.022) airways symptoms and less days with salbutamol inhalation (12.2% vs 16.9%, p < 0.001) were reported by cases than by controls. The episodes of upper respiratory symptoms were shorter [4.3 days (95%CI:3.8-4.9) vs 5.7 days (95%CI:5.0-6.4), p = 0.007] but not less frequent [2.3 (95%CI: 1.8-2.8) vs 2.6 (95%CI:2.2-3.0), p = 0.122] among cases than among controls. Similarly, the episodes of lower respiratory symptoms tended to be shorter [3.8 days,2) vs 4.4 days, (95%CI: 4.4-6.0), p = 0.067] but not less frequent [1.9 (95%CI:1.5-2.3) vs 2.1 (95%CI:1.7-2.4), p = 0.240] among the group using the nasal aspirator. Conclusions: In our pilot study, the use of an automatic nasal aspirator in children with a history of recurrent wheezing was associated with an improved respiratory health during the cold season.
