Similar to the complications of the Nuss procedure, the most likely complications of minimally invasive sternal sinker are pneumothorax, fixed frame displacement, and wound infection. 1, Pneumothorax: Pneumothorax occurring after roentgenography is mostly caused by a wire passing through the back of the rib cage and puncturing the pleura, which can be avoided by thoroughly expanding the lung mostly when closing the incision. 2, support frame displacement: minimally invasive sternal sinker is most likely to occur is fixed frame dislodgement, fixed frame dislodgement displacement is the most common cause of re-operation, the literature reports the incidence of 1.2% to 29.9%. For one week after surgery, no flexion, no violent rotation of the chest and waist, no rolling, keep lying down, and it is better to be assisted when getting up. After discharge, pay attention to the posture and position; no rolling, less flexion; usually war standing, walking to keep the chest and back straight, do not do rapid, violent upper body twisting, can prevent the fixed frame from dislodging displacement. 3, wound infection: because the fixed frame is located under the incision, especially in the chest wall of thin pediatric patients, once the wound infection is likely to remove the fixed frame. This requires intraoperative to minimize the damage to the tissue at the incision, suture the incision before thorough hemostasis, try to wrap the muscle fixator, and apply antibiotics to prevent infection. Sleep as flat as possible after surgery. Try not to perform antagonistic movements before taking the fixator to avoid collision in and around the wound and causing rejection of the plate and wire. Early removal of the plate affects the long term results. Pneumonia and pulmonary atelectasis may also result from bed rest or reluctance to cough up sputum due to pain after chicken chest surgery. It usually only prolongs the hospital stay and does not affect the prognosis. On the first day after surgery, you can get up and move around with assistance, strengthen respiratory physiotherapy, nebulized aspiration, and perform deep breathing exercises after waking up.
