Determinants of invasive ventilation in infants with acute bronchiolitis: an observational study of pre-hospital and in-hospital treatments

In infants with acute bronchiolitis, younger age, presence of atelectasis, and higher Wood-Dowes-Ferres scores at admission were associated with invasive ventilation. Medications were frequently administered to the patients before and during hospitalization. This study emphasizes the need to consider these factors when caring for these infants and for clinical protocols to reduce the use of medications before and during hospitalization.
