After a long period of time, here is what you should do if you find out that your child has (or is suspected to have) congenital heart disease. The first step is to quickly consult a cardiac surgeon for professional advice and to complete relevant tests as soon as possible. When we determine that a child has or is suspected to have congenital heart disease, because there are many types of congenital heart disease and the condition of the child varies greatly and changes quickly, we should consult a cardiac surgeon clinician as soon as possible to get professional advice and improve the examination (such as cardiac ultrasound, CT, etc.) as soon as possible according to the doctor’s requirements, and if the condition is serious, we should contact the hospital’s fast track medical service to get the child treated as soon as possible. Step 2: Children who do not need treatment for the time being should be fed carefully at home as recommended by the doctor. Some of the precordial diseases can be fed at home for observation and regular review because of the comprehensive consideration of the child’s young age and poor tolerance to treatment or a few diseases (such as small ventricular septal defect, atrial septal defect, etc.) have the possibility of closing by themselves and other factors. However, feeding at home should not be careless, to should pay attention to the following points: 1, feeding should be carefully and carefully, should not be too fast and too violent, to avoid choking and coughing; 2, avoid provoking the child, minimize crying, so as to reduce the burden on the heart and lungs. 3, to prevent colds, children with precordial disease are prone to sweating should be dried in a timely manner, the child’s home should keep the air circulation. Step 3: Regular review and follow-up of discomfort. In the first step of consultation with the clinician, we were informed of the date of review should be kept in mind, do not miss the time, delaying treatment. However, if the child has recently had any of the following conditions, an earlier review is required: 1. feeding difficulties, frequent sweating, and markedly increased bruising of the lips and end extremities 2.Recurrent and increasingly severe pneumonia. 3.Heart failure and hypoxic attackers. The above cases need to be reviewed immediately and early.
