Local anesthesia is only suitable for some surgical projects with shorter operation time and less trauma, and the whole process of breast augmentation with prosthesis from opening wound to implantation to scar treatment usually takes about 2 hours, which belongs to medium and large surgical projects with greater trauma and requires general anesthesia.

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, people unconsciously complete the operation under the condition of completely losing consciousness and pain, and the whole process is relatively comfortable.

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 high. 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.
