Persistent wheezing and laryngotracheitis occupy the leading part among ARIs in children of early age.The aim of our work was to evaluate occurrence of obstruction of respiratory tract among acute respiratory diseases in children's hospital.Methods. We performed a retrospective analysis of histories of children admitted at Department of respiratory infections of Saint Vladimir Childrens City Hospital in 2006-2007 and 2010-2011 years.Results. Our cohort included children with ARIs aged from 1 months to 15 years old (in 2006 - 2220, 2007 - 2455, 2010 – 3200, 2011 - 2960 children). Children with obstruction were mainly early age (from 1 months to 3 years old). We revealed high frequency of obstruction upper and lower respiratory tracts, most of these children had recurrent episodes in history.We have found reduction frequency of wheezing in different years of observation from 23.1% to 21.5% (2006 – 23.1%, 2007 – 38.3%, 2010 – 39%, 2011 – 21.5% of children with AIRs). Also we registered high occurrence children with obstructive laryngotracheitis (in 2006 – 42.5%, 2007 – 65.7%, 2010 – 50.4%, 2011 – 47% of children with AIRs). All children with obstruction received standard treatment.Conclusion: Reduction of frequency of wheezing and obstructive laryngotracheitis in children admitted at children's hospital is connected with introduction of modern principles of therapy obstruction of respiratory tract at a pre-hospital stage. %U https://erj.ersjournals.com/content/erj/40/Suppl_56/P4666.full.pdf
