Filter by:The investigators propose that paracetamol will be similarly effective to ibuprofen in treating PDA in the premature neonate, with fewer side effects.
To determine whether oral or intravenous ibuprofen has a better or same efficacy and tolerance in closure of patent ductus arteriosis in extremely-low-birth-weight preterm infants.
Patency of the ductus arteriosus (PDA) is functionally essential for fetal circulation, however persistence of ductal patency postnatally may have significant adverse hemodynamic effects in the neonate. Medical therapy for PDA predominantly involves the administration of one of two non-steroidal anti-inflammatory drugs: indomethacin or ibuprofen. Both of these therapies have been shown to be successful in mediating ductal closure in approximately 70% of treated infants. However, the need for a second course of treatment for PDA closure remains quite common. The investigators hypothesize that, because of small differences between the two drugs, a greater percentage of infants who did not respond to a first course of therapy with indomethacin will respond to a second course with ibuprofen than to a repeat course of indomethacin. As such, the investigators aim to compare secondary therapy with a repeat course of indomethacin to secondary therapy with ibuprofen in infants whose ductus remained patent after a first course of therapy with indomethacin.
The purpose of this research is to address the comparative effectiveness and harm of the therapeutics frequently given to pregnant women and their young infants including antibiotics, tocolytic agents, non-steroidal anti-inflammatory drugs, H2 blockers, and steroids. Our overall hypothesis is that the use of an existing electronic medical record with additional resources for precise data collection and 18 month follow up will successfully address current knowledge gaps in therapeutic effectiveness and relative therapeutic harm. We will use an existing electronic medical record into which detailed healthcare information is entered for over 100,000 newborns each year. These infants will comprise the "Source Cohort". Nested within that database, we will prospectively enroll 10% of the population (10,000 newborns) as the Follow-Up Cohort. The current electronic medical record for the Source Cohort does not capture therapeutic dosing with sufficient precision to conduct comparative effectiveness research sufficient to change medical practice. The proposed research will: 1) ensure accurate data collection through electronic monitoring and real-time quality assurance evaluation in the Source Cohort; and 2) conduct 18 months post-hospital follow-up for neurologic outcomes and disability for the Follow-Up Cohort. We will complete assessments of neurologic outcomes and disability using an interactive web-based system, mail, telephone follow up, and in-person examination.
The purpose of this study is to determine if increasing the ibuprofen dose will increase the likelihood of closing the patent ductus arteriosus in premature babies.
The primary objective is to evaluate the PDA closure rate of early vs. late use of Ibuprofen (Ibu). The investigators believe that early use of Ibu will have a higher PDA closure rate than later use of Ibu. Early use is defined as medication given before the infant reaches 96 hrs old. Late use is defined as medication given when infant is more than 96 hrs old. The secondary objective is to measure the stress hormone and metabolic response (plasma catecholamines, glucose, and lactate) of neonates undergoing Ibu treatment of the PDA. The investigators believe that early ibuprofen will blunt the stress response greater than later use.
The investigators propose the present study with the following aims: - to determine whether early patent ductus arteriosus (PDA) treatment with ibuprofen treatment at the onset of clinical symptoms is superior to late ibuprofen treatment only when symptoms of a hemodynamically significant PDA are present in the evolution of bronchopulmonary dysplasia (BPD) defined as duration of supplemental oxygen exposure during the first 28 days - to determine whether early PDA treatment with ibuprofen will be superior to late treatment with ibuprofen in efficacy of PDA closure, need for rescue therapy, need for PDA ligation and incidence of major complications of prematurity. Hypothesis: Early pharmacologic closure of PDA with ibuprofen will improve respiratory course and reduce BPD as reflected by a reduction in duration of supplemental oxygen during the first 28 days of age vs. late pharmacologic treatment with ibuprofen. Outcome variables: The primary outcome of this study is the number of days spent on supplemental oxygen by each infant during the first 28 days. Other outcomes to be determined between groups include: - Mortality - Other respiratory variables: total days on supplemental oxygen, days on mechanical ventilation, oxygen dependence at 36 weeks post menstrual age, age at final extubation. - Other respiratory complications: pneumothorax, pulmonary interstitial emphysema, need for high frequency ventilation, pulmonary hypertension - Efficacy of PDA closure: number of courses of medication required, need for ligation - Other neonatal complications: intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), retinopathy of prematurity (ROP), necrotizing enterocolitis (NEC), intestinal perforation, sepsis, renal dysfunction (oliguria, elevated creatinine) - Time to achieving full enteral feedings, time to regain birth weight, weight at discharge. - Length of hospital stay
This is a retrospective chart review to look at the timing of using indomethacin and ibuprofen for PDA closure for infants admitted into the NICU of the University of Utah Hospital from 1/2007-8/2008. The purpose is to compare the outcomes of medical intervention in preterm infants if intervention occurs day of life 4 or less, or day of life 5 or greater, with the birthdate being counted as day of life 1.
Approval of surfactant by the FDA in 1989 for the treatment of Respiratory Distress Syndrome (RDS) in premature infants greatly improved survival rates. Newer surfactants approved by the FDA were more concentrated and had a more rapid onset of action. The overall efficacy of newer surfactants appeared similar until in 2004, Ramanathan and colleagues suggested that a double dose of Curosurf improved survival in infants 25-32 weeks gestational age, compared to infants treated with Survanta, the most commonly used surfactant preparation in the United States. While the data was suggestive, it was not clear that the improvement in survival was reproducible or that Curosurf was responsible for the improved survival rates. The purpose of this study was to investigate the role of Curosurf in improving lung function and survival rates and reducing the complications of prematurity in very premature infants < 30 weeks gestational age at birth.
A large patent ductus arteriosus (PDA) is associated with congestive heart failure, pulmonary hemorrhage, chronic lung disease (CLD), necrotizing enterocolitis (NEC) and intraventricular bleeding. Indomethacin is the first line of treatment for PDA. Failure of ductal closure with the first course of indomethacin is reported in 30-40% of infants, with a higher failure rate in infants weighing < 1000 gm. PDA ligation is associated with early postoperative hypotension, oxygenation failure and adverse neurodevelopmental outcome in preterm infants. The use of escalating doses of Indomethacin in the treatment of persistent PDA was found to be safe and decreased the need for PDA ligation without adverse effects in one observational study.We hypothesize that the use of an escalated dose of intravenous indomethacin will result in an increase in the probability of survival without need for surgical ligation of PDA as compared to a standard dose indomethacin in newborn infants < 29 weeks of gestational age with persistent PDA.
