Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Initial echocardiogram will be done by by the expert personnel (either medical officer or technician) - to assess the size of patent ductus arteriosus, left atrium / aortic ratio (LA/AO), and shunting direction of patent ductus arteriosus (PDA). If the patient fulfill the inclusion criteria and exclusion criteria and has hemodynamically significant PDA with echocardiography evidence, patient will be randomized for either treatment oral paracetamol or intravenous paracetamol.
Oral paracetamol will be administered orally either directly oral or through an orogastric tube at 15 mg/kg per dose in 6 hourly intervals for 3 consecutive days. The serving of medication will be signed and monitored on the patient’s medication chart.
Echocardiography assessment will be done after 24 hour post completion of each course of the investigational treatment (last dose of the course) by the expert personnel (either medical officer or technician), verified by paediatric cardiologist.
If echocardiography assessment showed PDA still open after first course of paracetamol treatment, patient will receive another course of similar route of paracetamol for 3 days and reassessment will be done after 24 hour complete treatment.
If PDA fails to close after second course, patient will be given the rescue therapy based on patient’s condition (ibuprofen/indomethacin) and they will be fully managed by the hospital neonatal team.
After they complete second course of investigational treatment, either PDA close or still open post second treatment, they are considered complete our trial and we will monitor the complication until 30 days post completion of treatment. Subsequently, if they fail the rescue therapy, patient will undergo surgical/medical intervention based on their suitable condition and this will be fully managed by the neonatal team

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
At randomisation, 50% of the infants will be allocated to the active treatment of oral paracetamol, while the other 50% will have the intravenous paracetamol.
The enrolled patients will be allocated with the treatment arm using sequentially numbered, opaque, sealed and stapled envelopes. The parents, hospital staff, and medical personnel directly involves in the patient’s care are blinded to group allocation. Corresponding envelopes are opened only after the enrolled participants complete all baseline assessments and it is the time to allocate the intervention.
After acceptance of a patient by the panel, the appropriate numbered envelope is opened; the card inside will reveal the patient will to be an O or a I case, and this information is noted to the medical officer in charge to be endorsed. (O = Oral paracetamol, I = Intravenous paracetamol)
Oral paracetamol or intravenous paracetamol will then administer by the neonatal intensive care unit nurses based on the route stated in the envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The patient will be randomly assigned following simple randomization procedures (by computer-generated random numbers) to one of the 2 treatment groups (oral paracetamol or intravenous paracetamol) with 1:1 ratio.
The person who will generate the random sequence will not involve in any other aspect of the trial.

Statistical methods / analysis
Sample size is calculated using Arifin W.N. sample size calculator (version 2.0) 2017
Previous study by Rania A et al (2019) reported that the mean ductal diameter is significantly reduced after the first course of oral paracetamol with standard deviation of 1.06 and 0.4 after second course of oral paracetamol. Based on our clinical experience, 1 mm difference is significant for ductal diameter reduction after treatment with paracetamol.
Thus, this study will need 24 patients in each group to be able to reject the null hypothesis that the proportion between the groups are equal, with the power of study 0.90. The Type 1 error probability associated with the test of this null hypothesis is 0.05. Taking into accounts 10% drop rate, total sample size required is 27 in each group.

Summary
Brief summary
Background: Persistent patent ductus arteriosus (PDA) is diagnosed when the ductus arteriosus fails to close after 72 hour of life. The shunting of the circulating blood volume from the systemic to the pulmonary circulation may cause pulmonary overflow and impaired end organ perfusion. Therefore, treatment of PDA is important to prevent these complications.

Hypothesis: the oral paracetamol is better than the intravenous paracetamol in treatment of premature neonates with hemodynamically significant patent ductus arteriosus.

General Objective
To compare the efficacy and safety of intravenous paracetamol versus oral paracetamol in premature neonates with patent ductus arteriosus

Specific Objectives
1. To compare the number of complete closure of patent ductus arteriosus (Echo verified) in premature neonates following treatment with oral paracetamol versus intravenous paracetamol
2. To determine the safety profile of oral paracetamol and intravenous paracetamol in premature babies with patent ductus arteriosus

Trial Design
Single centre, randomized control trial (RCT) involving premature neonates with gestational age of 26 – 33 weeks 6 days who are admitted to Neonatal Intensive Care Unit (NICU) Hospital Universiti Sains Malaysia in Kelantan, Malaysia.

Patients who meet the inclusion criteria will be randomized and started on the 3 days course of investigational treatment. Parental consent will be taken before starting this study. Patients are randomly assigned to one of investigational treatment with allocation ratio of 1:1. Echocardiography assessment will be done after 24 hour complete treatment. If PDA remains open after first course, the patients will be treated with another course of similar route of investigational treatment.

If PDA fails to close after second course, patient will be given the rescue therapy based on patient’s condition (ibuprofen/indomethacin) and they will be fully managed by the hospital neonatal team. After they complete second course of investigational treatment, either PDA close or still open post second treatment, they are considered complete our trial and we will monitor the complication until 30 days post completion of treatment. Subsequently, if they fail the rescue therapy, patient will undergo surgical/medical intervention based on their suitable condition and this will be fully managed by the neonatal team.

Early complications during treatment and late complications during 30 days post completion treatment are observed to assess the safety of paracetamol in patent ductus arteriosus.
