The characteristic signs of patent ductus arteriosus in children are

Patent ductus arteriosus (PDA) in children is usually characterized by a continuous heart murmur and requires prompt medical attention for evaluation and treatment. The ductus arteriosus is an important channel in the fetal blood circulation. It should usually close after birth, but in some infants it remains open, which may cause abnormal blood flow and heart stress. Characteristic signs of PDA include a machine murmur, which is a continuous murmur audible when the heart is auscultated and is usually more obvious near the lower edge of the left clavicle. PDA may also cause symptoms such as rapid heartbeat, rapid breathing, feeding difficulties, poor weight gain, and easy fatigue in infants and young children.

For parents, knowing these signs of PDA can help identify problems early and take their children to the doctor in time. During routine physical examinations, doctors will also detect this abnormality through auscultation and recommend an echocardiogram to confirm the diagnosis if necessary. Some babies' PDAs may close on their own, especially in premature babies. However, if the PDA fails to close within a certain period of time, the chance of failure to adjust on its own increases. The doctor may recommend medication, catheter intervention, or surgery to close the duct to avoid further health problems in the heart or lungs.

In daily care, parents should pay attention to their children's breathing, heartbeat, and overall growth and development. If any abnormal manifestations are found, the pediatrician should be contacted as soon as possible to ensure that the child receives professional diagnosis and treatment. Once PDA is diagnosed, it is very important to follow the doctor's orders for regular follow-up. Parents must prevent their children from infection, because PDA increases the risk of endocarditis in children. Learning to identify related symptoms such as fever, fatigue, or unexplained rash can also help with early intervention to avoid serious complications. Most importantly, don't be afraid to consult a professional doctor's advice, because timely treatment and observation can greatly improve quality of life and health prognosis.
