About

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.

180 participants in 2 patient groups

Ibuprofen in continuous (24 hours) iv infusion and EchoG

Experimental group

Description:

The first dose of ibuprofen will be 10 mg / kg to be administered as a continuous infusion for 24 hours. An echocardiogram will be performed before each of the following 2 doses of 5 mg / Kg and will only be administered if it meets echocardiographic criteria that indicate open DA (observation of ductus permeability with color Doppler regardless of its size). Each dose will be administered as a 24-hour continuous infusion.

Treatment:

Drug: Ibuprofen in continuous (24 hours) iv infusion and EchoG

IV bolus Ibuprofen slow (15 minutes) and EchoG

Experimental group

Description:

The first dose of ibuprofen of 10 mg / Kg to be administered in slow iv bolus (15 minutes). Before each of the following 2 doses of 5 mg / Kg, echocardiography will be performed and will only be administered if it meets the echocardiographic criteria indicated by open DA (observation of ductus permeability in color Doppler regardless of its size). Each dose will be administered in iv boluses in 15 minutes

Treatment:

Drug: IV bolus Ibuprofen slow (15 minutes) and EchoG
