With the rapid development of cardiac surgery technology and the increasing update of cardiac surgery instruments and equipment, brought about the rapid development of infant cardiac surgery, at present, it can be said that cardiac surgery has no age limit, as small as a few months, or even a few days after birth can receive cardiac surgery treatment, and for some cardiac surgery, like aortic and pulmonary artery transposition of aortic transposition, the earlier the surgery, the greater the chance of successful surgery For complex congenital heart disease and non-surgical treatment of Farrow’s tetralogy, 50% of children die within 2 years of age. Large ventricular septal defects and most complex congenital heart diseases also die within the first year of life due to pneumonia and heart failure. Therefore, the development of infant and child cardiac surgery not only has good social and economic benefits, but also reflects the level of cardiac surgery, but also reflects the overall level and comprehensive strength of a hospital, which is of great significance to the long-term development of cardiac surgery. First, the need to carry out infant cardiac surgery 1, infant cardiac surgery and coronary surgery are two active and full of potential in the development of cardiac surgery, representing the direction of development of cardiac surgery, is an important growth point for cardiac surgery. In recent years, 10Kg children have been operated successfully, and good results have been achieved for children under 5Kg. 2. Minimally invasive surgical closure of atrial septal defect, ventricular septal defect and patent ductus arteriosus not only simplifies the operation and trauma to the children, but also improves the success rate of the operation. 3.It is conducive to the exercise, development and improvement of the overall level of cardiac surgery and related departments. 4.It is conducive to the sustainable development of cardiac surgery, increasing the number of cardiac surgery and improving the competitiveness of our cardiac surgery department. 5.It has good social and economic benefits. Its hospital deposit is generally 30,000 yuan. Second, the conditions for carrying out infant cardiac surgery 1, good anesthesia techniques for infants and young children: infants and young children intravenous infusion line to establish and small arteries and veins of puncture placement are infants and young children anesthesia is a difficult problem. For critically ill patients, rapid anesthesia is also required to establish extracorporeal circulation as soon as possible. 2.Smooth extracorporeal circulation technique, pre-filling of extracorporeal circulation fluid and management of extracorporeal circulation for infants and children also have strange peculiarities. 3.Fine and skillful surgical operation technique, inserting 5 tubes in a small egg-sized heart is a more difficult operation space which is already very limited. 4, high-performance infant ventilator, ventilator is not only a respiratory support measures after cardiac surgery for infants and children, but also its effective treatment means. 5, highly responsible, and has a solid basic knowledge of cardiac surgery monitoring and operating experience of the nursing team.
