What are the drugs used to treat patent ductus arteriosus?

What are the drugs for treating patent ductus arteriosus? After the occurrence of patent ductus arteriosus, it will definitely bring too much harm to the patient. Once patent ductus arteriosus occurs, we must insist on treatment and care, but people don’t know much about the treatment methods of patent ductus arteriosus. Here we will introduce to you the drugs for treating patent ductus arteriosus.

The ductus arteriosus was originally a normal blood flow channel between the pulmonary artery and the aorta during the fetal period. Since the lungs do not have respiratory function at that time, the pulmonary artery blood from the right ventricle enters the descending aorta through the ductus, while the blood from the left ventricle enters the ascending aorta. Therefore, the ductus arteriosus is necessary for the special circulation mode during the embryonic period. After birth, the lungs expand and assume the function of gas exchange. The pulmonary circulation and systemic circulation each perform their respective duties. Soon the ductus will close automatically due to disuse. If it continues to not close, it will constitute a pathological condition, which is called patent ductus arteriosus.

Prevention and treatment of infective endocarditis, respiratory tract infections and heart failure with cardiotonic diuretics and oxygen inhalation.

We should pay attention to preventing the occurrence of infective endocarditis in our daily lives. For example, children must take antibiotics under the guidance of a doctor before and after tooth extraction and tonsil surgery.

For premature infants with patent ductus arteriosus, 0.2-0.3 mg/kg of indomethacin or 20 mg/kg of aspirin can be taken orally 4 times a day to inhibit prostaglandin synthesis and close the ductus. For older children or adults with pulmonary hypertension, tamponade or closure agents can be injected through the catheter to block the shunt.

The patent ductus arteriosus of the child is relatively large. Due to the large blood flow, the blood volume in the lungs increases. Children under 1 year old often suffer from complications such as pneumonia and heart failure. Parents should take their children to the hospital for treatment in time and actively use antibiotics.

Premature infants with patent ductus arteriosus often experience breathing difficulties and heart murmurs soon after birth. At this time, doctors will use oral or intravenous indomethacin to promote closure of the ductus, depending on the condition.
