Filter by:We hypothesize that feeding preterm infants while they receive indomethacin or ibuprofen therapy for treatment of a patent ductus arteriosus will decrease the incidence of feeding intolerance and shorten the time period that infants need to tolerate full enteral nutrition. We also hypothesize that this intervention will minimize the alterations in intestinal permeability that occur with these drugs and will improve the infants' hemodynamic response to enteral nutrition
Premature babies are affected by a condition known as "patent ductus arteriosus" in which the ductus arteriosus (a normal structure) fails to close after birth as it should. A very large ductus can put extra strain on the heart and lungs, making the baby's breathing dependent on a mechanical ventilator. Attending physicians can close the duct with medical\or surgical treatment but assessing whether this is justified can be difficult. The physician usually bases this decision on assessment of the baby's general condition and an ultrasound evaluation of the heart (called an "echocardiogram") but the last is particularly dependent on availability of skilled operators. The investigators have examined whether blood levels of a hormone called B-type natriuretic peptide (Nt pro-BNP)in the first week of life predict the need to treat a ductus arteriosus. This hormone is produced by the heart if it is under strain. If the test is helpful it could reduce dependence of physicians on echocardiography by skilled operators. Babies who were recruited had blood samples collected on days 1, 2, 3 and 7 for measurement of Nt pro-BNP. Each baby also had an echocardiogram performed between the fifth and seventh day of life. Decisions about treatment of the duct were made by attending physicians independent of the study. Physicians, investigators and echocardiographers were blinded to knowledge of the Nt pro-BNP concentration. Nt pro-BNP was also measured before and after treatment in all babies who had a PDA treated and echocardiography performed to confirm closure. Receiver operating characteristics (ROC) curves were used to assess the predictive value of Nt pro-BNP for samples collected at each time point. The investigators also compared the Nt pro-BNP levels in samples collected before and after treatment to assess the usefulness of Nt pr-BNP as an indicator of duct closure.
The objective of this study is to investigate the safety and effectiveness of the ADO II in patients with a PDA.
it is a prospective randomized simple-blinded pilot trial with the principal aim to compare efficacy and tolerance between oral ibuprofen and intravenous ibuprofen in early curative closure of PDA in very low birth weight infants. The likelihood of ductal closure with only one or two doses of treatment is a secondary objective.
AGA-004 - The objective of the study is to determine safety, effectiveness and clinical utility of the AMPLATZER Duct Occluder in patients with patent ductus arteriosus. AGA-007 - The objective of this study is to evaluate the long term safety and effectiveness issues that may not have have been adequately addressed during AGA-004.
The aim of the study was to evaluate BNP in preterm infants < 28 weeks on the second day of life, when it is still unknown, if a patent ductus arteriosus is hemodynamic significant or not. We hypothesized that high plasma BNP concentrations on day 2 are associated with the need of PDA intervention in the further course.
A patent ductus arteriosus (PDA) is associated with increased morbidity in premature infants. Standard indomethacin treatment is associated with intestinal and renal morbidity. B-type natriuretic peptide is elevated in significant PDAs. This study will determine whether BNP guided therapy could reduce doses of indomethacin.
The purpose of this study is to determine whether closure of the PDA in premature neonates using IV ibuprofen vs continuous IV indomethacin has different side effects, eg. effects on renal function, on blood flow velocity in the superior mesenteric artery, the anterior cerebral artery, and the renal artery.
The purpose of this study is to determine the safety and effectiveness of ibuprofen l-lysine iv in premature infants in the early treatment of Patent Ductus Arteriosus.
Purpose of the study: 1. To evaluate renal function maturation within the first month of life in very premature infants. 2. To determine whether a treatment with Ibuprofen for patent ductus arteriosus would alter renal function maturation at short term and up to 28 days of life.
