Below is a list of the following four major points, including strict control of salt intake and not eating too much chocolate and other sweets. First: Strictly control the intake of salt. Salt is mainly composed of sodium and chlorine, and sodium in the body has the role of “hydration” tissue, most of the body’s sodium and chlorine are excreted from the urine. The high concentration of sodium ions in the blood will cause a large amount of water retention in the body, resulting in generalized edema, liver enlargement, increase the burden on the heart, and in severe cases, can also lead to heart failure. At the same time, too salty diet is also an important cause of hypertension. So the diet of children after congenital heart disease surgery must be lighter, salted products, salted eggs, salted fish and other foods containing too much salt try not to eat. Secondly: it is not advisable to eat more chocolate and other sweets. After heart surgery, when the children do not want to eat, many parents like to stuff chocolate to the children to eat, thinking that this can ensure nutrition. Chocolate is mainly composed of fat and sugar, calories are very high, but the proportion of protein and fat and the normal needs of children is very different. Eat more chocolate easy to cause pediatric indigestion, constipation, loss of appetite. At the same time, chocolate contains caffeine and other ingredients, eating too much will not only make the children over-excited, affecting the rest, but also on the children’s brain development to bring certain adverse effects. Third: it is not advisable to eat more canned drinks and cold drinks. Canned beverages sold on the market a wide variety of drinks, many of the ingredients are mainly sugar or saccharin, spices, coloring and water, nutrition is often insufficient. Cold drinks are also children’s favorite food, but after major surgery children’s digestive organs are still in the stage of recovery and adjustment, when the children’s digestive function is often weaker. Too cold food into the stomach will stimulate the gastric mucosa vasoconstriction, gastric juice secretion decrease, affecting the food in the gastrointestinal tract digestion process; at the same time will also weaken the ability of the digestive tract sterilization, resulting in gastrointestinal tract infectious diseases. Fourthly, it is not advisable to take ginseng blindly. Some parents think that ginseng has a tonic effect, so they give ginseng soup to their children after surgery. Ginseng does have the function of strengthening the heart and body, replenishing qi and generating fluids, but different ginsengs have different properties, and taking improper ginseng will cause symptoms such as loss of appetite, nose bleeding, and irritability. Some other supplements are not suitable for children during growth and development.
