Severe Bronchiolitis Clinical Trial
Official title:
Prone Position Effects on Work of Breathing and Intrinsic PEEP in Children With Severe Acute Viral Bronchiolitis
Acute viral bronchiolitis is the first cause of respiratory distress in infant. Airway inflammation increases the respiratory system resistances and dynamic hyperinflation. This leads to an increase in the work of breathing. In Chronic obstructive pulmonary disease patients as in neonates, prone position (PP) improves lung function and decreases the end expiratory lung volume. The investigators hypothesized that in infants with severe bronchiolitis, prone position reduces the intrinsic Positive End Expiratory Pressure (PEEPi) and the work of breathing (WOB). The investigator designed a prospective randomized crossover study with 16 infants younger than six months who need ventilatory support by nasal continuous positive airway pressure (nCPAP) for severe acute viral bronchiolitis. Work of breathing (product time pressure) and PEEPi will be estimated using an esophageal pressure probe in prone and supine position.
