Filter by:Presence of Patent Ductus Arteriosus is detrimental to an infant born prematurely. The primary objective is to study the efficacy of Paracetamol (proposed new treatment) in treating haemodynamic significant Patent Ductus Arteriosus (hsPDA) in comparison to Ibuprofen (current standard treatment) in preterm infants. Outcome of such treatment will check on the conversion of hsPDA to non-hsPDA. All preterm infants (born at <32 weeks gestational age or birth weight < 1500 grams) with haemodynamically significant patent ductus arteriosus (hsPDA) who are ≤ 28 days old will be included over 2 years. Sample size 32. Secondary outcomes of this study will compare 1) BPD (broncho-pulmonary dysplasia) free survival at 36 weeks post menstrual age (PMA), 2) incidence of complications of prematurity in each group and 3) to record any evidence of adverse effects with Paracetamol or Ibuprofen.
In preterm infants with neonatal respiratory distress syndrome (RDS), exogenous pulmonary surfactant(PS) replacement therapy is one of the most important therapeutic breakthrough to reduce neonatal incidences of bronchopulmonary dysplasia(BPD) and/or death. But not all preterm infants with RDS can be beneficial. Otherwise, the international neonatal acute RDS (NARDS) collaborative group provides the first consensus definition for NARDS in 2017. And whether or not PS being beneficial in preterm infants with NARDS remains unknown.
The aim of this study is to investigate whether there is a relationship between echocardiographic measurements regarding closure of PDA and serum D-Dimer and Fibrinogen levels in premature infants born before 32nd gestational week and weighing less than 1500 grams.
The investigator's purpose is to study the population pharmacokinetics of paracatamol and ibuprofen in neonates with patent ductus arteriosus (PDA) and assess the feasibility of dosage individualization.
The purpose of this post-marketing clinical use database surveillance is to observe the frequency, type, and degree of adverse device effects and adverse events in order to assure the safety of the medical device, and to collect safety and efficacy information for evaluating the results of its clinical use.
Respiratory distress syndrome (RDS) is among the most common complications of preterm birth, and typically becomes manifested soon after birth. A failure of the rapid reuptake of fetal lung fluids after birth, with subsequent liquid retention in the alveolar space, together with the deficit of surfactant proteins ensuing from lung immaturity represent the leading mechanisms for the development of RDS, which may require different levels of respiratory support. An increasingly used method for the evaluation of the neonatal lung is pulmonary ultrasound, which allows assessing alveolar fluids and other pathological conditions in a non-invasive manner, and has been shown to predict the need for respiratory support and for surfactant administration in preterm infants with RDS. However, this method requires specific training, is operator-dependent and does not provide a trend able assessment over time. Transthoracic electrical bioimpedance (TEB) allows continuous and non-invasive monitoring of static and dynamic thoracic fluids. It has been recently introduced in neonatal clinical practice to assess such hemodynamic parameters as cardiac output and also quantifies static thoracic fluids contents (TFC). This method provides continuous and non-operator dependent data on the pulmonary fluid status over time and does not require specific training. The combination of lung ultrasound with TEB could open to new diagnostic and prognostic perspectives in preterm infants with RDS.
Patent ductus arteriosus (PDA) is the most common cardiovascular problem that develops in preterm infants. Persistent PDA may result in higher rates of death, chronic lung disease (CLD), pulmonary hemorrhage, necrotizing enterocolitis (NEC), acute kidney injury (AKI), intraventricular hemorrhage (IVH) and cerebral palsy. Currently available options to treat a PDA include indomethacin, ibuprofen or acetaminophen followed by surgical or interventional closure of the PDA if medical therapy fails. Wide variation exists in PDA treatment practices across Canada. A survey conducted through the Canadian Neonatal Network (CNN) in 2019 showed that the most common choice of initial pharmacotherapy is standard dose ibuprofen. In view of the high pharmacotherapy failure rate with standard dose ibuprofen, there is a growing use of higher doses of ibuprofen with increasing postnatal age (with 32% of respondents currently adopting this practice) in spite of the fact that effectiveness and safety of higher ibuprofen doses have not been established in extremely preterm infants [<29 weeks gestational age (GA)]. In view of this large practice variation across Canadian neonatal intensive care units (NICUs), we are planning a comparative effectiveness study of the different primary pharmacotherapeutic agents used to treat the PDA in preterm infants. Aims Primary: To compare the primary pharmacotherapeutic practices for PDA closure and evaluate their impact on clinical outcomes in extremely preterm infants (<29 weeks GA) Secondary: To understand the relevance of pharmacotherapeutic PDA treatment with respect to clinical outcomes in the real world. Methods: Participants: Extremely preterm infants (<29 weeks gestational age) with an echocardiography confirmed PDA who will be treated according to attending team Interventions: 1. Standard dose ibuprofen [10-5-5 regimen, i.e., 10mg/kg followed by 2 doses of 5mg/kg at 24h intervals] 2. Adjustable dose ibuprofen [10-5-5 regimen if treated within the first week. Higher doses of ibuprofen up to a 20-10-10 regimen if treated after the postnatal age cut-off for lower dose as per the local center policy] 3. Intravenous indomethacin [0.1-0.3mg/kg every 12-24h for a total of 3 doses]. 4. Acetaminophen [Oral/intravenous] (15mg/kg every 6h) for 3-7 days Outcomes: Primary: Failure of primary pharmacotherapy (Need for further medical and/or surgical/interventional treatment following an initial course of pharmacotherapy). Secondary: (a) Receipt of 2nd course of pharmacotherapy; (b) Surgical/interventional PDA closure; (c) CLD (d) NEC (stage 2 or greater) (e) Severe IVH (Grade III-IV) (f) Definite sepsis (g) Stage 1 or greater AKI; (h) Post-treatment serum bilirubin; (i) Phototherapy duration; (j) All-cause mortality during hospital stay.
Persistent ductus arteriosus (DA) is a common entity in the premature newborn and is associated with high morbidity and mortality. There is still controversy about which is the best treatment for its closure. Children with AD who receive pharmacological treatment present more frequently than other premature children, necrotizing enterocolitis or isolated intestinal perforation. At the present time, the conventional treatment of DA consists in the administration of intravenous ibuprofen, slow bolus in 3 daily doses 10-5-5 mg / kg / day. Recently, it has been observed that treatment with ibuprofen in continuous iv infusion for 3 days seems to be more effective in closing DA than conventional treatment for 3 days with the same dose but in slow iv bolus. This experimental treatment reduced the incidence of associated necrotizing enterocolitis. Our group demonstrated in a previous pilot trial that the guided treatment with echocardiography (EchoG) of DA with ibuprofen compared with conventional treatment, allows to reduce the number of doses to the patient. The EchoG treatment thus presents a potential reduction of side effects associated with medication, this resulted in a tendency to have a lower incidence of necrotising enterocolitis in the experimental group. This multicenter clinical trial aims to test the hypothesis that the combination of 2 experimental treatments, the use of ibuprofen in continuous perfusion and EchoG, reduces the incidence of digestive side effects (necrotising enterocolitis or isolated intestinal perforation) compared to the treatment also guided by echocardiography but slow bolus iv.
Patent ductus arteriosus (PDA) is an important morbidity of that the diagnosis and treatment is controversy in premature infants. A number of scoring systems have been developed, including the findings of echocardiography on the diagnosis and treatment of PDA. This study aimed to develop a new clinical scoring system that will enable the rapid, standard and noninvasive evaluation of hemodynamically significant PDA earlier, without relying on echocardiographic findings in premature babies with extremely low birth weight, and to determine the role of this scoring system in early diagnosis and treatment.
Multicentric, double-blind clinical trial, which will evaluate the efficacy of iv paracetamol versus standard treatment with ibuprofen in the closure of patent ductus arteriosus in the preterm newborn. Secondarily, we intend to compare the safety of both treatments, increase our knowledge about the pharmacokinetics, pharmacodynamics and pharmacogenetics of paracetamol and ibuprofen in the neonatal period and make a pharmacoeconomic assessment of the use of both drugs.
