Prophylactic IV Paracetamol in Extremely Premature Infants

Purpose of the research Everyone is born with an opening between the chambers of the heart, called a ductus arteriosus. In most people, it closes on its own, but in infants born at less than 30 weeks or less than 1250 grams, there is a higher chance that it won't close on its own. So we give drugs to make it more likely that it closes. There are different medications that can do that, so we want to compare them to find which has the best effect. Type of Research Intervention The drug will be given at age of 6 hours, then every 6 hours through IV. Participant selection We are inviting suitable children with gestational age less than 30 weeks or birth weight less than 1250 grams. Voluntary Participation Your participation in this research is entirely voluntary. It is your choice whether to participate or not. Whether you choose to participate or not, all the services you receive at this clinic will continue and nothing will change. If you choose not to participate in this research project, you will offered the treatment that is routinely offered in this hospital for the disease, and we will tell you more about it later. You may change your mind later and stop participating even if you agreed earlier. The drug we want to give is paracetamol, it is a safe drug that has been tested on children of this age and proved to be safe. It has also been tested for this disease and shown to be effective. Some participants in the research will not be given this drug. Instead, they will be given Indomethacin, which is the most commonly used to prevent Ductus Arteriosus. Procedures and Protocol To compare the different medications, you will be randomly chosen as to whether you will receive which drug. Standardly, different hospitals offer different treatments for the prevention of PDA. Some offer paracetamol, some offer indomethacin and some offer nothing. We will compare these options. An echocardiography (imaging of the heart) will be done after 72 hours to check if the ope
