Effect of Heliox on RSV Bronchiolitis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03171142
Recruitment Status : Completed

Brief Summary:
Helium is an inert gas with a density almost one-seventh of that of air. Based on its properties breathing a mixture of helium and oxygen (heliox) will lead to a reduction in resistance through narrowed airways and consequently decreases the work of breathing. Participating infants with RSV acute bronchiolitis will be supplied with heliox (ration of 21 oxygen and 79 helium) delivered through a flow nasal cannula to evaluate heliox effect in improving their oxygenation. Heliox will act as an additive therapy to improve oxygenation in patients with lower respiratory tract infection caused by respiratory Syncytial Virus (RSV) and will decrease the need for more complicated therapies.

Drug Information available for: Heliox

Arm Intervention/treatment
Active Comparator: Heliox group
receive Helium oxygen mixture 21:79 via nasal cannula 2L/min
Drug: Heliox
Heliox (21:79) via nasal cannula 2 litter per minutes

Active Comparator: Air group
receive oxygen 21%via nasal cannula 2L/min
Drug: Air
Air 21% via nasal cannula 2 litter per minutes

Primary Outcome Measures :
  1. Improvement in oxygenation [ Time Frame: change from baseline at 24 hours after treatment ]
    Arterial blood samples will be withdrawn through an arterial stab to determine partial pressure of arterial oxygen (PaO2)

Secondary Outcome Measures :
  1. improvement of respiratory distress [ Time Frame: change from baseline at 24 hours after treatment ]
    measured by the Modified Wood's Clinical Asthma Score
