With the advancement of relevant medical technologies, pediatric cardiac surgery techniques have become quite mature, and age and weight are no longer the main factors limiting surgery. Pediatric patients are not the epitome of adults, and postoperative management is completely different from adults, with its own characteristics and rules. This places a higher demand on postoperative monitoring and care in pediatric cardiac surgery. How to make your child safely through the postoperative recovery period of precordial disease? Cheng Duan, Department of Cardiac and Macrovascular Surgery, Xinjiang Cardiovascular and Cerebrovascular Hospital Post-operative monitoring: Unlike adults, children under 3 years of age, especially infants and children under 6 months of age, have immature functional development of various organs and extremely poor adaptability after surgery. The function of the heart, brain, lungs, kidneys and other important organs of children after heart surgery is in an extremely unstable state, so they must be monitored and cared for intensively in the cardiovascular care unit. The monitoring room is equipped with precise medical monitoring equipment suitable for pediatric patients and high level pediatric professional monitoring physicians and nurses, which provide 24-hour continuous monitoring of the child’s vital signs. Through monitoring, abnormal changes are detected in a timely manner, accurate calculations are made, and timely treatment is provided to ensure that the function of each organ of the child is in a stable state, so that the child can safely pass the most dangerous stage after surgery. It can be said that under the premise of satisfactory correction of cardiovascular malformation and good protection of important organs such as heart and lungs during surgery, postoperative monitoring is the key to improve the success rate. Post-operative care: Generally, after the child’s condition stabilizes 1 to 3 days after surgery, the child is transferred from the monitoring room to the general ward, and while cooperating with the doctor’s active treatment, the parents’ careful care is also important. First of all, try to keep the child quiet, avoid excessive crying, and ensure sufficient sleep. It is advisable for the child to eat less and more meals, not to drink a lot of soup at once, to ensure sufficient protein and vitamin intake, to eat as diversified and easily digestible as possible, and to keep the bowel movement smooth. Keep air circulation in the ward, let the child sit up, turn over, pat the back and cough up sputum to reduce the chance of respiratory infection. The child’s heart function has not fully recovered after surgery, and he or she sweats a lot, so it is necessary to keep the skin clean and change clothes regularly. The child can move appropriately, paying attention to the principle of gradual progress and not fatigue. Post-operative follow-up: Some families think that after the heart surgery is done, the child is discharged from the hospital and the child is completely well. In fact, it takes a long time for the heart to fully recover after surgery, usually about 3 months, and some children have to continue to take medication after discharge. Therefore, it is important for children to come to the hospital for regular follow-ups after discharge, and to continue to take medication and diet under the guidance of the doctor, so that the child’s heart function can recover smoothly.
