Most children with congenital heart disease have preoperative augmentation of the precordial region or pheochromocardium of different severity, and the median incision will make it obvious after surgery; children without preoperative augmentation or pheochromocardium may also have changes in the median incision after surgery. The sternum can be flattened and fixed with the use of a chicken chest control device to make it grow smoothly and beautifully. If you have any questions about the process of treatment of chicken chest with the chicken chest control device, you can contact me by telephone consultation. In addition, silicone scar spirit can be used to soften the scar tissue and make the wound more flat. Precautions are as follows: 1, the chicken breast treatment instrument began to use after discharge from the hospital, continue to wear for 6 months. 2.24 hours continuous use, charging 3 times a day for 30 minutes each time. 3.Please tighten the band when using (to the extent that the skin is not strangled red and can be stretched into the pinky finger for the right elasticity). 4, the summer heat, can cause prickly heat, eczema growth, can reduce the appropriate wearing time, wear the prevention and control instrument should be avoided due to prickly heat leading to skin infections eventually lead to sepsis. 5.Sleeping in supine position or side lying position can be adopted to avoid pressure on chest wound. 6.The scar patch can be used repeatedly and cleaned with cool water, not with hot water or sterilized water. Can be used at the same time with the chicken breast control device, scar paste use 6-9 months. (For details, please refer to the instructions.) Parents must read the above precautions carefully to ensure better recovery of their children after surgery. If parents have any other questions about their child’s post-operative period, especially for some out-of-town patients, they can contact me by phone consultation and I will try to talk to you on the same day.
