Patent Ductus Arteriosus in Premature Neonates

Abstract: Persistent patency of the ductus arteriosus is a major cause of morbidity and mortality in premature infants. In infants born prior to 28 weeks of gestation, a hemodynamically-significant patent ductus arteriosus (PDA) can cause cardiovascular instability, exacerbate respiratory distress syndrome, prolong the need for assisted ventilation, and increase the risk of bronchopulmonary dysplasia, intraventricular hemorrhage, renal dysfunction, intraventricular hemorrhage, cerebral palsy, and mortality.

“…Patent ductus arteriosus is an important clinical problem associated with exacerbation of respiratory distress syndrome (RDS), pulmonary hemorrhage, prolonged use of assisted ventilation, bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), renal dysfunction, necrotizing enterocolitis (NEC), periventricular leukomalacia (PVL), cerebral palsy and mortality in prematurity. 1 Classical hypothesis considering ductal closure includes fetal patency maintained by low oxygen tension and vasodilator prostanoids including prostaglandin E2 (PGE2) and prostacyclin (PGI2). Increase in PaO 2 and decrease in PGE2 and PGI2 after birth induce constriction of smooth muscle cells in the ductus arteriosus (DA) and result in functional closure of DA.…”

“…15 En el momento del nacimiento, al iniciar la respiración el RN, los pulmones se expanden y la saturación de oxígeno se eleva, esto da como resultado vasodilatación pulmonar y disminución en la resistencia vascular pulmonar con aumento de la resistencia vascular sistémica, que lleva a la inversión del flujo de sangre que se encontraba de derecha-izquierda, a pasar de izquierda-derecha a través del ductus. 3 El cierre funcional se produce horas después del nacimiento (entre 10 y 72), pero en la mayoría de los RN pretérmino, por lo general con peso inferior a 1.500 g y con síndrome de dificultad respiratoria del RN, este proceso se altera. El cierre espontaneo del DAP ocurre en cerca de 34% de los neonatos con peso muy bajo al nacer entre los 2 y 6 días de edad posnatal.…”

“…2 El DAP afecta al 80% de los recién nacidos de extremo bajo peso al nacer (< 1.000 g), al 45 % de los recién nacidos con peso menor a 1.750 g y sólo a uno de cada 5.000 RN a término. [2][3]18 No se encontraron estudios de incidencia de DAP en UCIN en Colombia, solo reportes de caso y un estudio de prevalencia realizado en Manizales por Acosta y col. donde se halló una prevalencia de DAP de 27.6% de todas las cardiopatías congénitas encontradas en un período de ocho años. 19 3.…”

“…Indomethacin is classically administered as 3 bolus doses at 12 h intervals although several different regimens for both Indomethacin and Ibuprofen have been described [50]. Indomethacin mediated reduction in systemic blood flow may be ameliorated by slowing the infusion rate to 20-30 minutes [51] or by continuous administration [52].…”
