RSV in severe cases may be necessary to provide intravenous (IV) fluids and humidified oxygen. Mechanical ventilation is a breathing machine 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.
Twins comprised 7.6% (66/875) of hospitalized infants with RSV bronchiolitis during the study period. Infants in the twin group were younger (122.4 +/- 131.7 vs. 204.5 +/- 278.8 days, P = 0.014), had a lower mean gestational age (35.3 +/- 2.6 vs. 38.6 +/- 2.5 weeks, P < 0.001), and were more likely to have been born prematurely compared with singleton infants (65.6% vs. 13%, P < 0.001).
