Is patent ductus arteriosus normal in newborns?

Patent ductus arteriosus in newborns is a common phenomenon, but whether it is normal needs to be determined based on the specific situation. The ductus arteriosus is a blood vessel that connects the aorta and the pulmonary artery during the fetal period, and usually closes within a few hours to a few days after birth. If it does not close, it may affect heart function and requires timely evaluation and treatment.

1. Causes of patent ductus arteriosus

Genetic factors may affect the closure of the ductus arteriosus, and some families have a genetic predisposition. Environmental factors such as infection during pregnancy, medication use, or maternal diabetes may also cause the ductus arteriosus to close. Physiological factors include delayed closure of the ductus arteriosus in premature infants because their development is not yet fully mature. Pathological factors such as congenital heart disease or other systemic diseases may also affect the closure process.

2. Treatment of patent ductus arteriosus

For asymptomatic mild patent ductus arteriosus, doctors may recommend observation and regular echocardiography. Indomethacin or ibuprofen are commonly used for drug treatment to promote ductal closure by inhibiting prostaglandin synthesis. Surgical treatment includes ductal ligation and minimally invasive occlusion, which are suitable for children with obvious symptoms or ineffective drug treatment.

3. Daily care and precautions

In terms of diet, breastfeeding is the best choice to ensure balanced nutrition. In terms of exercise, avoid strenuous activities and focus on light activities, such as massage or passive exercise. Regularly follow up heart function, monitor growth and development indicators, and detect abnormalities in time.

Whether the patent ductus arteriosus of a newborn is normal depends on the specific situation. Early detection and early treatment are the key. Parents should closely observe their children's performance. If they have symptoms such as shortness of breath and feeding difficulties, they should seek medical attention in time. Through scientific treatment and daily care, most children can restore normal heart function and grow up healthily.
