Factors Associated With Failure of Non-invasive Ventilation in Preterm Neonates Requiring Initial Respiratory Support.

Background: Non-invasive ventilation (NIV) modalities minimize the requirement for invasive mechanical ventilation (IMV) in preterm neonates, therefore improving neonatal outcomes, as IMV is linked to increased complications. However, NIV has demonstrated an elevated likelihood of failure, for which various studies have been done, but very little research is available addressing the factors that are responsible for NIV failure in resource-limited areas of developing nations. Understanding the underlying factors and their association with NIV failure in very and moderately preterm neonates at a tertiary care hospital would be important in devising targeted strategies to increase NIV success and newborn outcomes.
