E.3 | Principal inclusion criteria |
Male or female preterm infants with no limitation of race.
Gestational age 25+0-31+6 weeks.
Age 24-72 hours.
Echocardiographic evidence of hemodynamically significant patent ductus arteriosus at the first 24-72 hours of life.
The diagnosis of hemodynamically significant PDA requiring treatment will be made by echocardiographic demonstration of a ductal left-to-right shunt, with a left atrium-to-aortic root ratio >1.3 or a ductal size >1.5 mm and excluding the cases in which the closing flow pattern suggests a restrictive PDA [Varvarigou 1996, Su 2008].
Willingness of the parents/legally authorized representative/child to sign the Informed Consent Form.

Neonati pretermine maschi e femmine con nessuna limitazione etnica.
Età gestazionale 25+0-31+6 settimane.
Età 24-72 ore.
Evidenza ecocardiografica di dotto arterioso pervio ed emodinamicamente
significativo tra le prime 24-72 ore di vita.
La diagnosi di dotto arterioso pervio ed emodinamicamente significativo, che
richiede trattamento, sarà effettuata tramite evidenza ecocardiografica di shunt
duttale sinistro-destro, con rapporto tra atrio sinistro e radice aortica >1,3 o una
dimensione del dotto >1,5 mm ed escludendo i casi in cui il pattern del flusso
suggerisce un PDA restrittivo [Varvarigou 1996, Su 2008].
Volontà dei genitori, o del rappresentante legalmente riconosciuto, del bambino a
firmare il modulo di consenso informato. |

Hydrops fetalis.
Pulmonary hypertension diagnosed in the first 24-48 hours of life by means of heart ultrasound when the presence of a right-to-left shunt through the foramen ovale or ductus arteriosus is demonstrated, or when the estimated pulmonary pressure, in terms of the tricuspid regurgitation jet, is greater than two-thirds of the systemic arterial pressure.
Grade 3 or 4 intraventricular haemorrhage (IVH).
Urine output <1 ml/kg of body weight/h during a 24 h collection period or urine output <0.5 ml/kg of body weight/h in case it is measured at 24 hours of life of newborn.

Severe liver failure, defined as elevated liver enzymes (ALT/GPT and AST/GOT) > 2 times the upper boundary of the normal range. For this kind of population the following normal ranges will be considered [Rosenthal, 1997]:
- ALT/GPT: 6-50 U/L
- AST/GOT: 35-140 U/L
Medical need of administering other Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) different from ibubrofen.

termini di rigurgito tricuspidale è maggiore di due terzi rispetto la pressione
arteriosa sistemica.
