Congenital heart disease has an impact on the growth and development of children, with shortness of breath, dyspnea, malaise and severe cyanosis after activity or exertion. Due to their low resistance, children are prone to respiratory infections, lung infections, and recurrent attacks, which can easily lead to congestive heart failure. Children with tetralogy of Fallot often have fainting or convulsions due to cerebral hypoxia after crying or activity, and severe attacks can lead to death. How should a child with congenital heart disease be cared for at home? 1, daily life smart arrangements: both to enhance exercise, improve the body’s resistance, but also to rest properly, avoid overwork. If the child is competent, he or she should try to live and study together with normal children, but should prevent strenuous activities. At the same time, children should be educated to have confidence in the treatment of the disease and reduce pessimism and fear. 2. Indoor air circulation is desirable: windows should be opened regularly in winter to enhance air convection. Children with persistent bruising should avoid high indoor temperatures, which can lead to sweating and dehydration. 3.Reasonable diet: Give a high protein, high calorie, vitamin-rich diet to enhance physical fitness. Avoid eating too much. Children with cyanotic heart disease should be given enough water to avoid dehydration that may lead to thrombosis. Infants with congenital heart disease are more difficult to feed, and they tend to stop sucking because of shortness of breath when sucking, and they are prone to vomiting and sweating a lot, so a dropper can be used when feeding to reduce the physical exertion of the child. After feeding, gently lay down on your side to prevent vomit inhalation and asphyxia. 4.Emotional excitement should be avoided: try not to make the child cry and reduce unnecessary stimulation so as not to increase the burden on the heart. 5, bowel movements should be kept: for children with cyanotic type, do not use too much force when passing stool, so as not to increase the burden on the heart. If there is no stool for two days, you can use the open plug laxative to pass stool. 6, a large number of infusions need to be prohibited: if you must infuse fluids, the drip rate must be slow to prevent the burden on the heart, resulting in heart failure. 7, special position can be maintained: children with tetralogy of Fallot take a squatting position, and often take the initiative to squat for a moment when walking or playing. This is because squatting can make the symptoms of hypoxia relieved, if the child has this phenomenon, parents must not forcibly pull the child up. 8. Vaccination should be considered: children who usually have good heart function and activity endurance should receive vaccination according to the time, but after vaccination, systemic and local reactions should be observed more often for timely treatment. 9. Avoiding infection is the key: children with congenital heart disease are weak and prone to infections, especially respiratory diseases, and are prone to heart failure, so careful care should be taken to increase and decrease clothing with the change of seasons. If a family member has an upper respiratory tract infection, isolation measures should be taken, and children should be taken to public places as little as possible. Once the child has an infection, the infection should be actively controlled. 10, critical moments to the hospital: if the child is found to have shortness of breath, irritability, rapid heart rate, breathing difficulties and other symptoms, heart failure may occur, should be promptly sent to the hospital for treatment.
