After surgical treatment, the child with congenital heart disease has been corrected and the parents have been relieved of a “heart disease”. As the saying goes: patient recovery “three parts are treatment, seven parts depend on care”. Although the successful discharge of the child after surgery is a great success, but not everything is fine, post-surgical care is essential for the full recovery of the child. The main aspects of care for children after discharge are as follows: (1) Wound care The main surgical incisions for children with congenital heart disease are median sternal incision (front), such as the implementation of ventricular septal defect, tetralogy of Fallot and other intracardiac direct vision surgery. The other type of incision is the thoracic incision (lateral), such as for procedures such as patent ductus arteriosus and aortic constriction. With the improvement of medical sutures, most of the incision sutures for congenital heart disease surgery are now absorbable sutures, so the incision does not need to be removed after surgery (except for chest tube sutures). However, it is still very important to keep the area around the wound clean and dry after surgery. Children with precardiac disease are prone to sweating, so parents can wipe their children’s bodies with hot water frequently after discharge, and it is best to change underwear once every 1-2 days. Sometimes blood scabs and occasionally small white threads can be seen at both ends of the wound, mostly because the absorbent threads sewn into the skin are not completely absorbed, parents do not need to tear them urgently, they will generally fall off on their own after a few weeks. It is normal for children to complain of itchy wounds after surgery, so it is important to avoid harassment or picking at the wound. (2) Medication management Many children with congenital heart disease, especially some severe and complicated children, need to take medication for a period of time after surgery, mainly cardiac drugs and diuretics. Some children with heart rhythm disorders also need to take anti-arrhythmic drugs. Parents of children who take medication after surgery must strictly follow the instructions of the doctor or nurse at the time of discharge, so that they can give their children medication on time and in the right amount. If the child is taking digoxin, the parents must routinely check the child’s heart rate before taking the medication, and must stop taking the medication if the heart rate is too slow. In addition, potassium chloride must be used in combination with diuretics. Children taking antiarrhythmic drugs need to be closely monitored and followed up regularly. Patients with valve replacement should be properly hydrated in summer, have their coagulation function monitored regularly, and adhere to daily anticoagulation such as warfarin. Because these drugs have some side effects, parents should never increase, decrease or stop the medication without permission. (3) Dietary care This is an important part of the child’s post-surgical recovery. The child needs proper nutrition after surgery, which is not only beneficial to the healing of the wound, but also to enhance the resistance of the child and promote the overall recovery of the body. The diet of children after surgery should be high in protein, low in fat, light and low in salt. For example, children can drink more fish soup, meat soup, chicken soup, etc. after surgery. After the soup is cooked, it is best to remove the oil from it and eat some lean meat in moderation. You can also drink milk, eat cereals, steamed eggs, etc. in the morning and evening. In addition, the child should also have a moderate amount of vegetables and fruits. It must be emphasized that the more the child eats after surgery, the better. Excessive intake, especially eating too much salt can increase the burden on the heart of the affected child. Generally speaking, it is admitted that the taste is heavier than that of pediatricians, and northerners eat more salty than southerners. Therefore, in the family of children with congenital heart disease, especially in the early post-operative patients should implement the system of sharing food, it is best to give the children to eat the dishes separately burned or in the process of burning but not yet put salt first part of the process, do not be adults can taste as the standard. (4) Psychological care People often say that children with congenital heart disease are particularly smart, they are not “lack of heart”, but “more heart”. This is because they are more intelligent than others, which is probably related to the fact that parents, relatives and friends often give more sympathy and care to children with congenital heart disease since they are small. But this wang wang can also bring some side effects. Children with congenital heart disease are often very capricious and self-centered, throwing tantrums, crying, dropping toys and sometimes even protesting with “hunger strikes”. Before surgery, many parents make concessions and accommodations, fearing that their children will suffer from hypoxic attacks (cyanotic children) or heart failure (congestive children). Some children are frail and sickly from childhood, and have little contact with the outside world and few activities in general, forming a timid and silent psychological state. Therefore, after the surgery of children with congenital heart disease, parents must pay great attention to the early education of children, to do “rules”, not to over-pamper the child, not only to make the child in the physical aspects of a smooth recovery, but also in the psychological aspects of healthy development. (5) Activities and sleep The early life of children with congenital heart disease after surgery should be regular, which is very important for the recovery of health. Many children look rosy and have good appetite when they are hospitalized, but soon after they are discharged home, they look pale, have edema, swollen liver and do not want to eat, which is often related to insufficient rest and improper diet of the children. After the child is discharged from the hospital, depending on the condition, he or she can do appropriate activities indoors and also go outdoors in the sun, but should not go to public places. Children need to take a nap for 1~2 hours after lunch every day. In particular, it is important to emphasize that children should not watch TV for too long after surgery. Although watching TV programs can enrich children’s knowledge and develop their intelligence, uncontrolled TV viewing not only affects children’s eyesight, but also hinders children’s normal rest, which is very unfavorable to the recovery of children with congenital heart disease after surgery.
