As parents of children, how to identify congenital heart disease as early as possible and achieve early treatment? There are two types of congenital heart disease: cyanotic and non-cyanotic: 1. Cyanotic congenital heart disease is easy to recognize because the face is cyanotic and the lips are blue immediately after the delivery of the newborn, so it should be seen by the doctor as early as possible for clear diagnosis and early treatment. 2.The non-cyanotic type of congenital heart disease is not so easy to recognize, because it does not have purple face and cyanotic lips in the early stage, so it is not easy to be detected by parents. The main early manifestations of non-cyanotic congenital heart disease are for parents’ reference when identifying congenital heart disease: 1, the baby’s cry is weak and feeble after birth. 2. The infant is weak in sucking milk, showing fatigue, stopping to eat milk, intermittent sucking, and often overflowing milk and choking cough. 3. The respiratory rate is significantly faster than that of infants of the same age, and it is more obvious during sleep. 4. The child often cries excessively, and bruises can be seen around the lips at this time. 5. The child is prone to sweating and weight gain is often not standard. 6.The child is prone to recurrent respiratory and pulmonary infections. 7.When visiting the doctor, a murmur of the heart can be heard on examination of the body, at which time an early cardiac ultrasound should be performed to clarify the diagnosis. Regardless of the type of congenital heart disease, once diagnosed, regular follow-up visits should be made to the hospital and treatment should be given when appropriate.
