Association of patent ductus arteriosus with extubation failure among preterm infants

The presence of symptomatic patent ductus arteriosus was associated with extubation failure. Further investigations are needed to establish whether there is a causal relationship between PDA and extubation failure and whether proactive screening for presence of PDA and treatment of the same, before extubation among these infants, improves chances of successful extubation and cardiorespiratory outcomes.
