Pediatric ventricular septal defects are one of the most common types of pediatric congenital heart disease, and these children are prone to lung infections and colds due to excessive blood in the lungs. A small percentage of these children have feeding difficulties, which can affect their growth and development, and therefore require prompt treatment. Pediatric ventricular septal defects are large and not closed, then need to be treated with surgery, but some children can be closed without surgery, so, under what circumstances surgery is more appropriate? First, the conditions of pediatric ventricular septal defect surgery 1, the size of the defect generally based on the size of the defect to determine the self-healing situation, if the ventricular septal defect is less than 5mm, the usual colds, pneumonia is not much, before the age of 5 years old can be regularly rechecked, and then do it before the age of schooling, there is a possibility of self-healing. If the ventricular isthmus is larger than 5mm, and you often have colds, pneumonia and fever, then you should have the surgery early. 2, the defect site The defect site is also the key to determine whether there is a possibility of self-healing, such as the pulmonary artery or double arterial under the defect (dry under the type), generally no self-healing, and easy to cause aortic valve prolapse and regurgitation, affecting cardiac function, it is advisable to early surgery. 3.Severe symptoms The children have growth retardation, repeated respiratory infections, congestive heart failure, feeding difficulties and other symptoms, and even complications of bacterial endocarditis, the drugs can not control early surgery is recommended. Instead, follow up every 3-6 months to see if the defect is self-healing. Note: Newborns or infants with large ventricular septal defects with high shunt flow, complicated by life-threatening persistent heart failure and pulmonary insufficiency, and ineffective active medical therapy, should create conditions for surgery, even within 3 months of birth. How to take care of pediatric ventricular septal defect after surgery 1, pay attention to the prevention of infection ventricular septal defect surgery to prevent infection, and, within three to six months to limit strenuous activities. 2.Reasonable diet After surgery for ventricular septal defect, family members should educate the patient to eat small meals, not too full, not to overeat, and try to control snacks, drinks, so as not to increase the burden on the heart. 3, take medication on time Patients with ventricular septal defects should not stop taking medication or increase or decrease the dosage of medication. Generally 3-6 months after the operation, you can go to school, and go to the hospital for rechecking after the operation according to the doctor’s instruction. 4, clean living environment Housing should be sunny, clean, warm and comfortable, regularly open the windows to ventilate the air, beds should be kept clean and comfortable, baby ventricular septal defect patients should be diligent after surgery to change clothes, to prevent skin infections. Third, pediatric ventricular septal defects need to pay attention to what 1, to avoid excessive crying, try to let the child to keep quiet, to avoid excessive crying, to ensure adequate sleep. Older children should live a regular life, combination of static and dynamic, strictly prohibit running and jumping and strenuous exercise. 2, avoid staying in crowded places, indoor air circulation, children try to avoid going to crowded public places, should be with the weather warm and cold timely increase or decrease in clothing, to reduce respiratory tract infections. If the stool is dry and difficult to defecate, excessive force will increase the abdominal pressure, aggravate the burden on the heart, and may even have serious consequences. Tips: pediatric ventricular septal defect is a congenital disease, and this disease occurs due to a combination of reasons. Congenital heart disease should be prevented before pregnancy, both husband and wife need to be exposed to bad habits, active screening for hereditary diseases, and active treatment of diseases affecting the fetus; during pregnancy to do a good job of pregnancy checkups, prevention of colds and flu, and it is best to avoid the use of drugs.
