Cleft lip and palate are congenital developmental malformations that require surgical solutions for cleft lip and palate deformities and tissue displacement defects. Surgery that is too large or when the child is too small requires cleft lip repair and cleft palate repair under general anesthesia, with the following main risks: 1. Bone dysplasia after surgery: some surgical methods must amputate the jaw bone, and after the developing jaw bone is amputated, it may affect the blood flow of the jaw or damage the growth center, resulting in the development of the upper jaw, lower jaw, and other facial bones not developing proportionally, causing shortening of the upper jaw; 2. Anesthesia risk: If the airway is obstructed, it can affect breathing. Children with cleft lip surgery are mostly 3-6 months old, younger in age, with incomplete development of trachea and airway, prone to edema, spasm, infection and inflammation during anesthesia intubation, all of which greatly increase the difficulty and risk of anesthesia operation; 3. Intraoperative blood loss: because the child cannot swallow well, acute obstruction of the respiratory tract can easily occur, resulting in respiratory impairment or even death; 4. Lung infection: if there are preoperative Slight infection symptoms or inflammation, intraoperative intubation may lead to the occurrence of pneumonia; 5, hemorrhagic shock: infants with small blood volume and a little more bleeding may easily cause hemorrhagic shock; 6, cleft lip and palate recurrence and cleft.
