Symptoms of patent ductus arteriosus in infants

summary

In daily life, most newborns have a variety of small diseases caused by different reasons after birth. At this time, we need professional doctors to help them take reasonable treatment measures and treatment programs. Generally, the catheter is small and the shunt is small; The number of premature infants with coarser patent ductus arteriosus was more than one week after birth. There are also some full-term infants, generally after 6-8 weeks, the pulmonary vascular resistance of infants decreases, the left to right shunt aggravates, and the symptoms begin to appear. Here's a brief introduction to common sense.

Symptoms of patent ductus arteriosus in infants

The symptoms of infants of different months are also different. In patients with large volume distribution, the left thorax is slightly elevated, apex pulsation is enhanced, localized tremor can be felt at the left edge of sternum, and there is a loud continuous machine like murmur in auscultation. Family members of patients may as well try to observe the symptoms of children. It is forbidden to infuse a large amount of fluids in order to avoid aggravating the burden on the heart and leading to heart failure.

A small number of children with large ductus arteriosus who survive without treatment will have irreversible pulmonary vascular lesions due to the increase of pulmonary vascular resistance. And the systolic blood pressure increased, diastolic blood pressure decreased, can appear peripheral vascular sign, such as pulse pressure difference increased, pulse flood, carotid artery pulsation enhanced, water pulse, nail bed or skin mucosa capillary pulsation sign, and can hear gunshot sound. Once the infection occurs, the infection should be actively controlled.

Finally, we should also know that children with PDA with large flow distribution are easily irritated, tachycardia, shortness of breath and difficult to feed. Simple PDA patients get compensation in childhood, few symptoms, but poor development, thin, easy to catch a cold and pneumonia, and not easy to cure. We should take some protective measures against this disease,

matters needing attention

Children with good cardiac function and activity tolerance should be vaccinated at that time, but after vaccination, systemic and local reactions should be observed for timely treatment. Avoid emotional excitement, try not to make children cry, reduce unnecessary stimulation, so as not to increase the burden of the heart, when necessary, to go to the regular hospital for treatment.
