Risk factors of symptomatic patent ductus arteriosus in very-low-birth-weight preterm infants
Keywords:
patent ductus arteriosus, very-low-birth-weight preterm infants, respiratory distress syndrome, maternal medical conditionsAbstract
Background: Symptomatic patent ductus arteriosus (PDA) can lead to complications, mortality and long term disability. Understanding the risk factors associated with symptomatic PDA can guide treatment and prevention.
Objective: To study the factors contributing to the development of patent ductus arteriosus and its associated complications in very-low-birth-weight (VLBW) preterm infants.
Methods: A retrospective study was conducted on very-low-birth-weight preterm infants diagnosed with symptomatic PDA who requiring treatment, compared with those without symptoms, from 2018 to 2023. Multivariate logistic regression analysis was used to find factors influencing the manifestation of symptomatic patent ductus arteriosus.
Result: Factors influencing the manifestation of symptomatic PDA included PDA size (aOR 67.41, 95%CI 6.47, 701.92), surfactant therapy for respiratory distress syndrome (aOR 43.04, 95%CI 2.66, 697.26). Complications associated with symptomatic PDA included increase in ventilator utilization (OR 26.74, 95%CI 0.35, 69.07), inotropic agents usage (OR 13.23, 95%CI 2.98, 58.71), bronchopulmonary dysplasia (OR 7.40, 95%CI 3.36, 16.30), and acute kidney injury (OR 10.23, 95%CI 1.26, 82.71).
Conclusion: The incidence of symptomatic patent ductus arteriosus requiring treatment in VLBW preterm infants is relatively high in Lampang Hospital. Reducing the incidence rate of respiratory distress syndrome in VLBW preterm infants may prevent this condition.
