Prostaglandin E1 in infants with congenital diaphragmatic hernia (CDH) and life-threatening pulmonary hypertension
2020, Journal of Pediatric SurgeryCitation Excerpt :Timing of the life-threatening event after birth (median 11 days) is also in accordance with a cause and effect relationship between restriction of the ductus arteriosus and the cardiorespiratory failure. Although the ductus arteriosus is functionally closed in 90% of healthy term babies by 72 h of life, infants with PPHN have a significant delay in ductal closure [13,14]. In this situation of cardiopulmonary failure, ECMO was shown to be effective [15].
Transitional hemodynamics in preterm neonates: Clinical relevance
2016, Pediatrics and NeonatologyCitation Excerpt :As a result of increasing effective pulmonary gas exchange and the circulatory changes, arterial oxygen saturation increases from 60–70% at 1 minute to above 90% within 10 minutes following delivery.13 To complete the transition, at least in term neonates, DA constricts within hours after birth and undergoes functional closure by 48–72 hours of life in the majority of healthy neonates.14 However, in preterm infants ductal closure is often significantly delayed.
Transitional cardiovascular physiology and comprehensive hemodynamic monitoring in the neonate: Relevance to research and clinical care
2014, Seminars in Fetal and Neonatal MedicineCitation Excerpt :In term neonates, a decrease in the heart rate with an increase in left ventricular stroke volume (SV) occurs [17]. The initial increase in the left ventricular output (LVO) peaks within the first 2 postnatal hours and is followed by a gradual decrease during the ensuing 22 h [18,39]. The decrease in LVO is attributed, at least in part, to the corresponding changes in blood flow through the ductus arteriosus with the initial constriction and subsequent closure of the duct.
Transitional changes in cardiac and cerebral hemodynamics in term neonates at birth
2012, Journal of PediatricsCitation Excerpt :They found a 2-fold increase in LVO at 1 hour after birth compared with in utero, followed by a decrease at 24 hours after birth, with no further change at 72 hours after birth. Walther et al7 studied the transitional circulation in healthy term infants from 30 minutes to 24 hours after birth and reported a decrease in LVO after the initial peak at 30-120 minutes. These results are consistent with our finding of decreased LVO at 26 hours after birth.
