Case: A newborn baby was born 10 days ago, the first child was born by normal delivery, weighing 3.5kg, and had good growth and development. However, on the second day after birth, the child occasionally appeared purple around the mouth, the parents did not pay attention to it, when the condition further deteriorated, only to come to the hospital, the examination was congenital heart disease, ventricular septal defect, the parents heard, at that time, full of tears. A. Why does a child get congenital heart disease? In fact, congenital heart disease is a more common childhood heart disease, the incidence of congenital heart disease in newborn infants in China is not low, the incidence of congenital heart disease in China accounts for about 5%, most of the congenital heart disease children, if early detection, are able to get early treatment, according to the condition of a reasonable choice of timing of surgery, timely surgery is expected to be completely cured. It does not affect the normal learning and growth of the child. If not detected in time, the treatment may be delayed, resulting in some complications and death. How can the disease be detected in the early stage? This requires further analysis by the doctor according to the child’s symptoms, together with various examinations, in order to make a clear diagnosis. The index data of pregnant women during physical examination or ultrasound can be used as the basis of judgment, but the disease is less found in the fetal period, and some babies can be found at birth, such as newborns with shortness of breath and heart failure. However, if the child usually has no symptoms, normal growth and development, and a lot of activity, like normal children, it is only easy to be found to have congenital heart disease only when the doctor finds heart murmur during physical examination when the child visits the doctor for cold or respiratory infection. Third, for this situation, as parents can learn from the following points whether the child has congenital heart disease. 1. Frequent colds. Children are more prone to colds than other children, and if they don’t pay attention to them, they will have fever, cough and sputum after almost 10 to 20 days. This is mainly due to some specialized pathophysiological processes, such as ventricular septal defect and atrial septal defect, which cause the blood that should be in the body circulation to flow into the lung circulation. In short, there is more blood in the lungs, like a culture medium, where bacteria and viruses are more likely to grow leading to colds or aggravate to pneumonia. 2, slow growth and development. Watching the children of the same age are growing taller and taller, the child’s weight is always not growing, and the size is low. This is mainly due to the slow growth of children with congenital heart disease, just like flowers do not get sunlight, rainwater irrigation, congenital heart disease children due to the pathological blood circulation, can not completely nutrients to the organism caused. 3. The lips of the mouth are purple. The child’s lips always look purple, how to look abnormal, this is also due to some complex malformations of congenital heart disease such as: Farrer’s tetralogy of Fallot, transposition of the great arteries, single ventricle, etc., some blood does not go inside the lungs for oxygenation, no oxygen blood color is black, so the most can show the blood color of the lips look purple purple. 4, inexplicable fainting, gasping for air. The child inexplicably faints and gasps for air with light activity, which is also mainly caused by some complex malformations of congenital heart disease, due to the inability of blood to perfuse the brain, as well as the need for more and more oxygen as the child grows older, but cannot satisfy itself, resulting in such and such symptoms. If your child has such a problem, it is important to seek early medical attention, because some congenital heart disease exists the best time to treat, if you miss it, then the effectiveness of treatment, the effectiveness of surgery will also decline with it. But here’s wishing all the children in the world are happy and healthy!
