Progress in the treatment of patent ductus arteriosus in extremely low birth weight infants / 国际儿科学杂志

ABSTRACT

With the progress of perinatal medicine and the improvement of cure rate in preterm infants, the diagnosis and treatment of patent ductus arteriosus in extremely low birth weight infants is a great challenge for neonatal medicine.Continuous left-to-right shunt through catheters can lead to systemic hypotension, pulmonary perfusion, increased left ventricular volume load, prolonged mechanical ventilation, and increased risk of complications and death such as pulmonary hemorrhage, bronchopulmonary dysplasia, necrotizing enterocolitis, and intraventricular hemorrhage.Conservative treatment is still the first choice and drug treatment is not completely effective, while the long-term impact of both on newborns is still unclear, which need a reasonable assessment of the pros and cons.Surgical ligation can improve cardio-pulmonary function, but the indication and time of the arterial catheter are also controversial for its self-closing, thus more evidence-based studies are needed.We review the current management status and controversy of patent ductus arteriosus in extremely low birth weight infants to explore the scientific and effective clinical measures.
