Congenital heart disease is the primary congenital defect disease that threatens the life and health of children with congenital heart disease. Because of the heart defect, most children with congenital heart disease have heart dysfunction, poor physical fitness and love to be sick than children of the same age, while waiting for surgery and after surgery, home care plays a vital role in the mitigation and recovery of the disease. So, what should be paid attention to in winter care for children with precordial disease at home? Preventing upper respiratory tract infection Children with ventricular and atrial defects and other precordial diseases have poor health, and a cold can easily trigger lung infection, leading to recurrent pneumonia, deterioration of heart function and heart failure. Prevention of upper respiratory tract infections in the cold winter is the first care, the main attention should be paid to do a good job of cold and warmth, while taking care not to wear too many clothes, so as not to sweat caused by secondary cold leading to cold; avoid crowded public places, so as to avoid infectious diseases; indoor regular ventilation, keep the air circulation; if the family has a cold, should avoid contact with the baby; take the baby more sunshine, more breathing Fresh air; give children to wear looser clothes, you can also put a small dry towel on the chest and back to avoid catching a cold when changing clothes frequently. Diet and nutrition Children with precocious heart disease generally have thin bodies, poor appetite, poor appetite, parents are afraid that their children’s nutrition can not keep up with the child’s tonic, and even eat appetizing drugs, in fact, these methods are not desirable. The crux of poor appetite lies in the child’s condition, and diet control is also a very important link, parents effectively and reasonably change the child’s diet to help strengthen the child’s body before treatment to accept the intensity of some high surgery, parents are advised to give their children more eggs, chicken, fish, milk, lean meat, fresh vegetables, these foods have high nutrition, but also easy to digest and absorb. The child’s poor resistance, easy to get sick, usually should pay more attention to appropriate exercise to enhance resistance. In fact, except for children with severe cardiac insufficiency or some special heart malformations, children with precordial disease can do more good than harm by participating in sports, but they need to pay attention to the correct amount of exercise for children and avoid strenuous exercise. The actual fact is that many parents are not convinced that the winter temperatures are low, so they should wear more clothes. Yes, cold will catch a cold, but the heart of children with prediabetes is already poor, too much clothing will not only increase the burden on the child, once sweating too much, it is also very likely to cause a cold, we should pay attention to this point. Parents are advised to change the child’s loose underwear and lining the chest and back with a small dry towel, so that the towel can be changed several times a day without changing clothes, so that the child can avoid catching a cold. The immunization is a very hot topic, can children with precocious heart disease be immunized? In fact, as long as there is no serious cardiac insufficiency, children can be immunized on time with various immunization programs, including BCG, polio vaccine, pertussis vaccine, diphtheria vaccine, measles vaccine, etc. to improve immunity to diseases. However, if your child has a fever, diarrhea, pneumonia, or other illnesses that prevent him or her from getting vaccinated, he or she can get the vaccination after these illnesses are cured. A few children with prediabetes have to take medication for a longer period of time, such as digoxin, Kepone and diuretics. These drugs have a strict method of administration, parents must follow the doctor’s prescription, on time, according to the dosage, can not arbitrarily increase or decrease the dose and stop the drug, otherwise it will affect the effectiveness of treatment, affect the accuracy of the doctor’s judgment of the condition, and may even cause the child drug overdose and poisoning. The infusion of large amounts of flu is often required when sick with a cold, and if a child with precordial disease must be infused, the drip rate should be slow to prevent increasing the burden on the heart and leading to heart failure. In addition to careful attention to diet and activities, it is also necessary to give sufficient attention to psychological aspects. The child should not be overly pampered, nor should the requirements be lowered because the child has heart disease, which will make the child have low self-esteem and timid psychology. First aid for hypoxia Children with cyanotic precordial disease can often have hypoxic episodes triggered by crying, defecation, cold or trauma during infancy, manifesting as irritability, difficulty in breathing, aggravation of cyanosis, weak crying, etc. In severe cases, it can be life-threatening. In such cases, parents should immediately administer oxygen, flex the child’s lower limbs, place the child in the chest and knee position, and go to the hospital as soon as possible.
