Title: Oral Paracetamol Versus Oral Ibuprofen Treatment
Brief Summary: The purpose of this study is to determine whether oral paracetamol or ibuprofen has a better or same efficacy and tolerance in closure of patent ductus arteriosus in preterm infants.


Options:
A: Inclusion Criteria:

* Birth weight below 1250 gram
* Diagnosed patent ductus arteriosus by Echocardiographic examination

Exclusion Criteria:

* Accompanied other congenital cardiac anomalies
* Urine output of less than 1 ml/kg/h during the preceding 8 h,
* Serum creatinine level \>1.6 mg/dl,
* Platelet count \<60,000/mm3,
* Liver failure,
* Hyperbilirubinemia requiring exchange transfusion
* Severe intracranial bleeding (Grade III - IV)
* Intestinal abnormality and necrotising enterocolitis
B: Inclusion Criteria:

* (1) Age over 18 years
* (2) Twin pregnant women at 34weeks 0days to 36weeks 5days of gestation
* (3) At risk for preterm birth such as preterm labor, preterm prematrue rupture of membrane or maternal-fetal indications that need preterm delivery. Preterm labor is defined as regular uterine contractions with or without the following symptoms; pelvic pressure, backache, increased vaginal discharge, menstrual-like cramps, bleeding/show, cervical changes
* (4) Availability of written informed consent.

Exclusion Criteria:

* (1) Gestational age before 34weeks 0days or after 36weeks 6days
* (2) Lethal major fetal anomaly, fetal distress or fetal death in utero
* (3) Expected to deliver within 12 hours; for example, advanced cervical dilatation (\>8cm) in preterm labor or active phase labor (cervical dilatation\>4cm) in preterm premature rupture of membranes
* (4) History of a previous administration of ACS before 34weeks of gestation for fetal lung maturation
* (5) Administration of systemic steroid for medical indications
* (6)Diagnosis of clinical chorioamnionitis Fever \>37.8 and the presence of two more following conditions: uterine tenderness, foul-odored vaginal discharge, maternal leukocytosis(\>1500), maternal tachycardia(\>100) or fetal tachycardia(\>160)
C: Inclusion Criteria:

1. Male or female preterm infants with no limitation of race.
2. Gestational age 25(+0) - 31(+6) weeks.
3. Age 24-72 hours.
4. 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.
5. Willingness of the parents/legally authorized representative/child to sign the Consent Informed Form.

Exclusion Criteria:

1. Outborn patients.
2. Major congenital anomalies, including but not limited to congenital heart defects, Down syndrome newborn and/or new born suffering from congenital anomalies diagnosed during the fetal period.
3. Known positive HIV and/or known positive Hepatitis C Virus newborn's mother.
4. Life threatening infection, complicated or not by multiple organ dysfunction and failure syndrome.
5. Fetal hydrops.
6. 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.
7. Grade 3 or 4 intraventricular haemorrhage (IVH).
8. 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.
9. Serum creatinine concentration \> 1.5 mg/dl (132 μmol/l).
10. Platelet count \< 50,000/mm3.
11. Major bleeding, as revealed by hematuria, or blood in the endotracheal aspirate, gastric aspirate, or stools, or consistent oozing of blood from puncture sites.
12. Severe liver failure, defined as elevated liver enzymes (ALT/Glutamate-Pyruvate Transaminase and Aspartate aminotransferase/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/Glutamate-pyruvate transaminase: 6-50 U/L
    * Aspartate aminotransferase/GOT: 35-140 U/L
13. Medical need of administering other Nonsteroidal Antiinflammatory Drug (NSAID) different from ibuprofen.
14. Participation to another trial involving any investigational drug.
D: Inclusion Criteria:

* Preterm infants of ≤32 weeks of gestational
* Preterm infants ≤ 1500 gram of birth weight

Exclusion Criteria:

* Major congenital abnormalities
* Neurological dysfunction
* Infants who were mechanically ventilated and/or sedated, hemodynamically unstable
* Infants \> 32 weeks of gestational
* The infants whose parents denied consent were also not included.
