& ltp> Prosthetic breast augmentation and plastic surgery hospitals are all under general anesthesia, and local anesthesia is not allowed. & lt/p & gt； Local anesthesia of<p> is only suitable for some surgical projects with shorter operation time and less trauma, while the whole process of breast augmentation with prosthesis from opening wound to implantation to scar treatment usually takes about 2 hours, which is a large and medium-sized surgical project with greater trauma and requires general anesthesia. & lt/p & gt； & ltp> General anesthesia is an anesthetic that acts on the central nervous system (brain and spinal cord) to inhibit it, showing that consciousness disappears and the whole body feels no pain, that is, when people completely lose consciousness and pain, they unconsciously complete the operation and the whole process is relatively comfortable. & lt/p & gt； & ltp> What needs to be emphasized here is that the risk of local anesthesia surgery is not small, and the risk of general anesthesia surgery is great. What kind of anesthesia is used mainly depends on the specific surgical method. In addition, anesthesia has been used in plastic surgery for a long time, and its safety is relatively high. Through a large number of clinical proofs, as long as there is no frequent anesthesia experience in a short period of time, a single anesthesia will not cause damage to the brain. & lt/p & gt；
