RSV in severe cases may be necessary to provide intravenous (IV) fluids and humidified oxygen. Mechanical ventilation is a breathingmachine to ease breathing. A nebulized bronchodilator such as albuterol (ProAir HFA, Proventil-HFA, Ventolin HFA) may be used to relieve wheezing. This medication opens air passages in the lungs. Nebulized means it's administered as a fine mist that you breathe in. Occasionally, a nebulized form of ribavirin (Virazole), an antiviral agent, may be used.
In Canada, RSV is responsible for 5800 to 12,000 hospitalizations annually, with a documented increase in the incidence of admissions for bronchiolitis over the past two decades. In the United States, between 1997 and 2000, RSV bronchiolitis comprised 77,700 admissions annually and was the leading cause among hospitalized infants younger than one year of age, with an additional 25% increase in hospitalization rate reported between 1997 and 2002 in this age group.
