Comparative Study between Noninvasive Continuous Positive Airway Pressure and Hot Humidified High-flow Nasal Cannulae as a Mode of Respiratory Support in Infants with Acute Bronchiolitis in Pediatric Intensive Care Unit of a Tertiary Care Hospital.

Background: Early initiation of appropriate noninvasive respiratory support is utmost important intervention to avoid mechanical ventilation in severe bronchiolitis.

Aim: This study aims to compare noninvasive continuous positive airway pressure (nCPAP) and hot humidified high-flow nasal cannulae (HHHFNC) as modes of respiratory support in infants with severe bronchiolitis.

Methods: Prospective, randomized, open-label pilot study done in a tertiary-care hospital Pediatric Intensive Care Unit (PICU).
