At present, the main incision for pediatric congenital heart disease surgery is the central incision and the right incision, the central incision has been used for many years, and with the demand for aesthetic incision, the right incision has been popularly used in the country for many years after its creation in the early nineties. The right side incision is relatively more painful than the right side incision; 3. The wire will be under greater force after the median incision, and the wire will be cut, and the sternum will need to be fixed by surgery again if necessary; the right side incision will be cut by the intercostal muscle due to the force, and the rib will need to be fixed by surgery again if necessary. 4, the median incision is suitable for most of the surgery, the field of view exposure is relatively clear, the right side of the incision has a selection of diseases, at present, basically applicable to atrial septal defect, ventricular septal defect, tetralogy of Fallot and other diseases with clear exposure, the range of disease types is relatively small; 5, the median incision postoperative scars are more obvious than the right side, especially for girls after adulthood, especially now focus on the psychological impact of children after surgery, the median incision The child’s psychological pressure is greater as he grows up, which is less conducive to psychological health; 6, the median incision is longer than the right incision due to the sternal restriction, and the damage to the child is relatively greater than the right incision; 7, the median incision appears after surgery because the sternum is cut and fixed again, and the postoperative chicken chest appears more than the right incision; for both incisions parents need to pay attention to the following aspects in the process of postoperative care: 1, the median incision Avoid the child’s arm extension force, that is, reduce the force on the sternum similar to the nature of push-ups, in order to reduce the force on the wire and avoid the wire cutting the sternum for secondary surgery. 2.After discharge, pay attention to wound hygiene, bathing is not recommended within one week to avoid wound infection, which can be wiped. 3.Some children will have suture rejection, and in serious cases, the incision will become pus, so they need to go to the hospital in time to deal with it and cut off the rejection wire; 4.Some children have repeated pus in the incision after surgery, so after excluding the suture rejection factor, we should suspect osteomyelitis, and in similar cases, we need to go to the hospital in time to diagnose and deal with it; 5.After removing the suture after surgery, children can use the treatment of chicken chest, scar removal paste, etc. For the larger heart with the incision in the middle For children with larger heart with median incision, it is recommended to use chicken chest treatment instrument and scar removal patch because the sternum is cut, and the effect of scar removal patch varies greatly among individuals.
