Effects and safety of hypertonic saline combined with airway clearance in non-hospitalized children with recurrent wheezing.

Background: The International Study of Wheezing in Infants defines recurrent wheezing as the presence of three or more medically documented episodes of wheezing within one year. To date, there is no evidence on the use of hypertonic saline (HS) combined with airway clearance techniques (ACT) for children with recurrent wheezing treated in an outpatient setting. Therefore, this is the first study to explore the use of such interventions in infants with recurrent wheezing.

Safety of airway clearance combined with bronchodilator and hypertonic saline in non-hospitalized infants with acute bronchiolitis.

Background: Acute viral bronchiolitis (AVB) is associated with significant morbidity and no study has addressed the safety of airway clearance techniques (ACT) for non-hospitalized infants. This study aimed to evaluate the safety of the use of ACT combined with bronchodilator and hypertonic saline in non-hospitalized children with the first episode of AVB.

Methods: A quasi-experimental study of infants aged 2-12 months, with a clinical diagnosis of AVB (mild to moderate), was performed.

Immediate Effects and Safety of High-Frequency Chest Wall Compression Compared to Airway Clearance Techniques in Non-Hospitalized Infants With Acute Viral Bronchiolitis.

Background: No studies have investigated the use and safety of high-frequency chest wall compression (HFCWC) for non-hospitalized infants with acute viral bronchiolitis (AVB). The aim of the present study was to evaluate the immediate effects and safety of HFCWC as compared to airway clearance techniques in children with AVB.

Methods: In this randomized clinical trial in non-hospitalized infants (0-12 months old) with mild to moderate AVB, children were randomized into 2 groups: airway clearance techniques (20 min of prolonged slow expiration and provoked cough) or HFCWC (15 min).
