Previously healthy infants may have increased risk of aspiration during respiratory syncytial viral bronchiolitis

Objective. Respiratory illnesses may cause feeding difficulties in infants. We studied the safety of oral feeding during respiratory syncytial viral ( RSV) bronchiolitis in previously healthy infants. Methods. Twelve previously healthy infants (3-12 months) with RSV bronchiol itis underwent barium swallow studies during the acute phase of illness. Th ose with abnormal studies underwent repeat studies 2 to 4 weeks later. Results. The initial barium studies revealed aspiration in 3 infants. All r epeat studies, performed 2 to 4 weeks later, were normal. Conclusions. Even previously healthy infants may be at risk of aspiration d uring RSV bronchiolitis.
