Be sure to have the necessary tests before surgery, such as ECG, blood count, and any bleeding disorders. Communicate carefully with the surgeon before surgery to understand the results, the way of surgery, possible complications and how to deal with them. Don’t do more than one part of the surgery at a time, such as multi-site liposuction. Don’t pursue perfection, for example, if more skin is removed for eye bag surgery, the lid may be ectropion, and if more fat is removed, it will be sunken. Do not do the surgery that can be done or not. Risky surgery depends on the availability of resuscitation measures. For example, bleeding, airway obstruction. The prosthesis placed in the body is regular, non-toxic, universal, removable and absorbable. Close observation after surgery is required to detect and deal with complications in a timely manner. Strictly follow the medical advice after surgery, such as activities, local compression, cold compresses, and observation.
