Insights
This study found no airway or pulmonary aspiration in infants hospitalized with moderate respiratory distress from respiratory syncytial virus (RSV) bronchiolitis. Swallowing evaluations were normal, indicating aspiration is unlikely in these cases.
Area of Science:
- Pediatrics
- Pulmonology
- Gastroenterology
Background:
- Respiratory syncytial virus (RSV) bronchiolitis commonly causes moderate respiratory distress in infants.
- The risk of aspiration (food or saliva) in these infants is not well-established.
- Understanding aspiration risk is crucial for appropriate clinical management.
Purpose of the Study:
- To evaluate the risk of airway and/or pulmonary aspiration in infants hospitalized with moderate respiratory distress due to RSV bronchiolitis.
- To assess swallowing function in infants experiencing their first wheezing episode.
- To determine if aspiration occurs in infants with moderate RSV bronchiolitis.
Main Methods:
- Prospective, descriptive study conducted over two RSV seasons.
- Inclusion criteria: otherwise healthy infants, first wheezing episode, modified Tal clinical score 5-9.
- Swallowing evaluation via technetium-99m colloid radionuclide salivagram and video fluoroscopy with contrast material.
Main Results:
- Fifteen infants (mean age 4.3 months) were included.
- All swallowing studies (salivagram and video fluoroscopy) were normal.
- No episodes of aspiration or laryngeal penetration were detected in any patient.
Conclusions:
- Infants hospitalized with moderate respiratory distress from RSV bronchiolitis do not appear to aspirate.
- Swallowing function is preserved in this patient population.
- Further research may explore aspiration in more severe cases or different etiologies.
Abstract:
The aim of this study was to evaluate the risk of airway and/or pulmonary food or saliva aspiration in infants with moderate respiratory distress who are hospitalized with respiratory syncytial virus (RSV) bronchiolitis. This prospective, descriptive study was conducted during two epidemic RSV seasons at the Ricardo Gutiérrez Children's Hospital in Buenos Aires, Argentina. Included were otherwise healthy infants in their first wheezing episode with a modified Tal clinical score between 5 and 9. Swallowing was evaluated using a dynamic technetium-99 m colloid radionuclide salivagram using a gamma camera, followed by video fluoroscopy using nonionic and ionic contrast material. Fifteen patients (7 boys) were included. Age at evaluation (mean ± SD) was 4.3 ± 1.5 months; clinical score was 7.5 ± 1.4. Patients required (mean ± SD) supplemental oxygen and hospitalization 7.5 ± 3.7 and 8.8 ± 4.3 days, respectively. All technetium-99 m salivagram (10/10, as the gamma camera equipment was out of service during part of the study) and video fluoroscopy (15/15) studies were normal. No episodes of aspiration or laryngeal penetration were detected in any patient. Our study found that infants hospitalized with moderate respiratory distress due to RSV bronchiolitis did not show aspiration.
