For the week ending June 29, 2012

Last week 258 articles were evaluated via DynaMed's Systematic Literature Surveillance and 140 were added to DynaMed content.   

 

Based on the editors' criteria of selecting "articles most likely to change clinical practice," one article of significant interest was selected for the DynaMed Weekly Update.

Feature Article

Nebulized Albuterol in Hypertonic Saline Rather than Normal Saline May Reduce Hospitalizations in Young Children with Acute Wheezing  

 

Virus-induced wheezing is a common cause of emergency department (ED) visits for young children, and symptoms often do not respond to bronchodilators and corticosteroids (N Engl J Med 2009 Jan 22;360(4):339,  N Engl J Med 2009 Jan 22;360(4):329).  There is previous evidence that nebulized hypertonic saline either alone or mixed with epinephrine may improve outcomes in infants with bronchiolitis (Cochrane Database Syst Rev 2011 Mar 16;(3):CD006458, J Pediatr 2010 Oct;157(4):630).  A new small randomized trial evaluated the effects of adding hypertonic saline to albuterol in 41 children aged 1-6 years visiting the ED with acute wheezing episodes.  Following a single inhalation of albuterol with normal saline, children were randomized to albuterol mixed with hypertonic saline 5% vs. albuterol mixed with normal saline.  The study drug was given twice in the ED with 20 minutes between doses and then 4 times daily if the child was admitted to the hospital.  Children with viral bronchiolitis were excluded.

 

Albuterol with hypertonic saline was associated with a significant reduction in hospital admission compared to albuterol plus normal saline (62.2% vs. 92%, p < 0.05, NNT 4)  The median hospital stay was 2 days with hypertonic saline vs. 3 days with normal saline (p = 0.027).  Clinical severity scores were significantly reduced in both groups compared to baseline, with no significant differences between groups (Pediatrics 2012 Jun;129(6):e1397).
