Association of patent ductus arteriosus with extubation failure among preterm infants.
BACKGROUND: Mechanical ventilation is associated with mortality/morbidities in preterm infants. Nearly a third of these infants fail extubation, and this may increase morbidities. OBJECTIVE: To evaluate the association of moderate to large symptomatic patent ductus arteriosus (PDA) with failure of extubation among preterm infants. METHODS: This was a retrospective study on preterm infants (birth weight <1250 g and gestational age ≥23 weeks) born between January 2009 and December 2016, who were mechanically ventilated and extubated within the first 60 days of age. RESULTS: Three hundred and sixty infants were evaluated, of these, 26% failed, and 74% succeeded in the initial extubation attempt. On adjusted analysis, symptomatic PDA was associated with an increased risk of extubation failure. CONCLUSION: 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.
