Plain English Summary

Background and study aims
Patent ductus arteriosus (PDA) occurs when a blood vessel in the heart does not close after birth. For most babies, this vessel closes in the first few days after birth. However, when babies are born early the blood vessel can remain open as it is unable to close on its own. This can cause the baby to have to work harder to breathe and prevent the baby from gaining weight. A PDA can be closed in a preterm baby over the first 48 hours by being given ibuprofen (an anti-inflammatory (swelling) medication) through a needle in a vein. Studies have shown this to be safe way to close the PDA and prevent babies from requiring surgery. In some countries, the medication is not available through a needle in the vein and therefore studies need to be done to see if medication being given through the mouth is safe and effective. Using paracetamol (a commonly used pain medication) to close PDA has been suggested as an alternative. This study aims to compare two different types of medication (ibuprofen and paracetamol) that are given to babies by mouth to see how well they work at closing the PDA.

Who can participate?
Premature infants and newborns that weigh less than 1500 grams

What does the study involve?
Participants are allocated to one of two groups. Those in the first group are given a syrup form of paracetamol by mouth every six hours for three days. Those in the second group are given a syrup form of ibuprofen once daily for three days. Participants are followed up with an echocardiogram (a scan that uses sound waves to create a picture of the heart) after 24 hours to see if the PDA has closed. If the PDA has not closed yet, participants will receive a second course of the same medicine. If the PDA has not closed after the second course of medicine, they are given the other medicine.

What are the possible benefits and risks of participating?
Participants will benefit from having the PDA closed. There are no risks to participating.

Patent ductus arteriosus (PDA)


Participants are randomly allocated to receiving either oral paracetamol or oral ibuprofen. Randomisation is done through a computer generated numbers placed in opaque envelopes with sequential numbers.

Group 1 (oral paracetamol): Participants receive 10 mg/kg/dose of paracetamol orally (as a syrup) followed by 1-2 cc 0/9% saline every six hours for three days.

Group 2 (oral ibuprofen group): Participants receive 10mg/kg/dose of ibuprofen orally (as a syrup) followed by 1-2 cc 0.9% saline once daily for three days.

An echocardiogram is done within 24 hours of last treatment dose to assess the PDA. If the treatment fails, another course of the same assigned drug is given. If the treatment fails after the second course of the same drug, the patient will receive the drug from the other group. Participants are followed up if there are respiratory distress symptoms.

Drug names

1. Paracetamol
2. Ibuprofen

Primary outcome measure

1. Closure of PDA is measured by an echocadiograph within 24 hours post treatment
2. Mortality is assessed through daily follow up of the patients and their medical records.

Secondary outcome measures

1. Respiratory distress syndrome (RDS) is measured using physical examination for clinical signs of respiratory distress and chest X-ray finding at baseline
2. Bronchopulmonary dysplasia (BPD) is measured using clinical examination of the patient for the need of respiratory support or supplemented oxygen at 36 weeks post conceptional age
3. Mechanical ventilation (MV) is measured using clinical examination and reviewing patient record any time during hospital stay until discharge
4. Necrotizing enterocolitis (NEC) is measured using abdominal X-ray for the presence of pneumatosis intistinalis any time during hospital stay
5. Retinopathy of prematurity (ROP) is measured using binocular indirect ophthalmoscopy exam at 32 weeks post conceptional age for premature infants born < 28 weeks gestation or at 4 weeks chronological age for premature infants born > 28 weeks gestation
6. Intraventricular hemorrhage (IVH) is measured using trans-fontanel cranial ultrasound at 7 days of age
7. Periventricular leukomalacia (PVL) is measured using trans-fontanel cranial ultrasound at one month of age
