3 Hypertonic Saline and Acute Wheezing in Preschool Children Pediatrics Vol June 2012.On line May 2012

4 Background Rhinovirus - common cause of lower airway inflammation Change in electrolyte and water movement on the luminal surface of epithelial cells similar to RSV infection increases ATPase leading to decrease ATP level This decreases electrolyte movement and dehydration at luminal level

5 Hypertonic saline in theory may reverse some of the physiologic abnormalities

6 CLINICAL QUESTION PopulationPreschool children Intervention5% Hypertonic saline ComparisonPlacebo OutcomeReduce hospitalisation and duration of stay DesignRandomised double blind controlled trial

7 Literature search Hypertonic saline and wheeze

8 Methods A prospective, randomized double-blind controlled trial to investigate the efficacy of inhaled HS treatment of 1to 6- year-old children presented to the ED with acute wheezing episodes from January 2009 to January 2011

9 Inclusion criteria were children aged 1to 6 years who presented with acute wheezing illness and a CS ≥6 During RSV season, 2 to 6-year-old children were recruited to exclude infants with RSV bronchiolitis
