Filter by:The ductus arteriosus (DA) normally closes after birth as a result of exposure to oxygen. Its persistence of DA (PDA) occurs in 20 to 50% of very preterm infants and is associated with significant morbidity and mortality: prolongation of respiratory assistance, pulmonary haemorrhage, -necrotizing enterocolitis (NECU), intraventricular haemorrhage and death. PDA management is one of the most discussed aspects in neonatology. The treatment is either conservative (controlled fluid intake, monitoring of cerebral flows, diuretics), or pharmacological (ibuprofen or paracetamol per os), or surgical (thoracotomy + ligature or catheterization + plug). The success rate of pharmacological treatment of CAP is 30% in the most immature children. When medical treatment fails, surgical or endovascular treatment is considered. However, these are associated with complications such as recurrent nerve lesion, thoracotomy, failure to close DA, migration of the plug. Therefore individualized assessment balances the expected benefits of CAP treatment against the risks associated with the treatments for each patient. The main complication of CAP is the impossibility of weaning the patient from ventilatory assistance. On the one hand because of PDA, but also very often because of the concomitant development of bronchopulmonary dysplasia (BPD) due to pulmonary lesions secondary to assisted ventilation and especially to inflammation. At 3 weeks of life, if attempts at ventilatory weaning have failed, postnatal corticosteroid therapy is considered in the 4th week of life in accordance with current recommendations. The most commonly used postnatal corticosteroids are dexamethasone (DXM), hydrocortisone hemisuccinate (HSHC) and betamethasone (BTM). DXM (intravenous) is effective and is the most widely used product worldwide, but its use is associated with impaired postnatal growth and suboptimal neurodevelopment. HSHC (intravenous) is an alternative to DXM and has shown some effectiveness, without the adverse effects of DXM. The BTM is also an alternative, but has been used less than the other products because it is not widely available in some countries. Its advantage is that it can be given orally, but there is little published data on the effect of BTM. In this context, it has been used in some neonatal units and have shown some effectiveness. In the Neonatology department of the Croix Rousse hospital, oral BTM has been used since 2005 and has been evaluated favorably, since it allows the child to be weaned from ventilatory assistance. When using BTM, we observed not only a positive respiratory effect, but also DA closure, reducing the need for ligation of the ductus arteriosus by surgery or catheterization

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.
The decision to treat patent ductus arteriosus in preterm infants, varies from a conservative, medical or immediate surgical treatment; although, at present, there is some controversy about this decision. This study aims to determine the efficacy and safety of surgical versus pharmacological treatment of patent ductus arteriosus in preterm infants.
Present randomized, controlled, double-blind trial investigates the efficacy and safety of early (<24 h) intravenous paracetamol therapy for pain medication in very small premature infants. This phase 2 drug study focuses on the efficacy and safety of short-term use. The pharmacokinetics and pharmacodynamics of paracetamol, as well as the long-term effects, are studied. This study recruits preterm infants born less than 32 weeks gestational age and treated at the neonatal intensive care unit of Oulu University Hospital. The informed consent is asked from all parents. The first drug dose is given before 24 hours of age. Masked study drug is paracetamol infusion solution 10 mg/mL or placebo, 0.45% saline solution. The loading dose is 20 mg/kg, and the maintenance dose 7.5 mg/kg every 6 hours for 4 days. The exact date of the closure of ductus is studied by repeated echocardiographic examinations. The symptoms of pain are screened by a pain scale of preterm infants (NIAPAS). Patients are monitored for signs of possible side effects. After discharge from hospital, patients are examined at follow-up clinic for the first year every 3 months and at 2 years of age.
