A Retrospective Analysis of Feeding Practices and Complications in Patients with Critical Bronchiolitis on Non-invasive Respiratory Support

Limited data exist regarding feeding pediatric patients managed on non-invasive respiratory support (NRS) modes that augment oxygentation and ventilation in the setting of respiratory failure. We conducted a retrospective cohort study to explore the safety of feeding patients managed on NRS with acute respiratory failure secondary to bronchiolitis. Children up to 2 years old with critical bronchiolitis managed on RAM, CPAP, or BiPAP were included. Of the 178 eligible patients, 64 were reportedly NPO while 114 were fed (EN). Overall equivalent in severity of illness, younger patients populated the EN group, while the NPO group experienced a higher incidence of intubation. Duration of PICU stay and NRS were shorter in the NPO group, though intubation eliminated the former difference. Within the EN group, ninety percent had feeds initiated within 48 hours and 94% reached full feeds within 7 days of NRS initiation, with an 8% complication and <1% aspiration rate. Reported complications did not result in escalation of respiratory support. Notably, a significant improvement in heart rate and respiratory rate was noted after feeds initiation. Taken together, our study supports the practice of early enteral nutrition in patients with critical bronchiolitis requiring non-invasive respiratory support.
