When it comes to liposuction, one of the topics that must be mentioned is: general anesthesia or local anesthesia for the surgery? Some candidates asked me, “Director Chen, does the surgery hurt? Is it possible to have general anesthesia?” There is more than one. In fact, liposuction surgery anesthesia and anesthesia way of also have a big door. The choice of anesthesia for liposuction is related to the following factors: (1) the amount of fat extraction; (2) the size of the liposuction area; (3) the patient’s health status and requirements; (4) the patient’s economic status. Liposuction anesthesia is performed by: (1) local infiltration anesthesia (super-wet and swelling anesthesia techniques) (2) conscious sedation techniques (combined with local swelling anesthesia techniques); (3) general anesthesia; (4) local nerve block anesthesia. Each type of anesthesia has its own indications, and there is no conclusive evidence as to which type of anesthesia is significantly safer and more effective than the others in fat aspiration. Before deciding on the type of anesthesia to use, the physician will be informed about the patient’s health, anxiety level, and specific factors related to anesthetic complications, such as allergies to anesthetics, which the patient should also inform the physician about in advance.
