At present, more and more people have improved their body shape, reduced their burden and obtained good plastic surgery results through liposuction, while some people have one or another problems after receiving liposuction, and there are even reports of life-threatening problems. So what are the possible complications of liposuction? How to prevent and treat these complications? Generally speaking, liposuction surgery can be divided into dry liposuction and wet liposuction. Dry liposuction is less used because it has more bleeding and is more dangerous, but at present, wet liposuction is more widely used, and we generally use wet over-expansion mechanical crushing negative pressure liposuction method, whose advantages are safety, quickness, no hospitalization, complete liposuction, less rebound and less complications. The following talks about the possible complications of this procedure and its preventive measures: 1, anesthesia accident and cardiovascular system accident during surgery: it refers to the accidental situation (rare) caused by anesthesia, etc. or the problem caused by surgical stimulation during surgery, which can be life-threatening in serious cases. The main preventive measures are to strictly grasp the indications before surgery, accurately understand the whole body, except various hidden diseases such as heart disease, hypertension, cerebrovascular disease, etc., and choose the appropriate anesthesia and anesthetic drugs, etc., and have good resuscitation conditions during surgery; 2. Intraoperative bleeding: dry liposuction has relatively large bleeding during surgery, while wet expansion liposuction has less bleeding. It is indispensable to understand the bleeding and coagulation function of the patient before the operation, and many factors such as the operation of the doctor and the preparation of the expansion agent are also very important. If the amount of bleeding is large, the patient should be treated with fluids and blood transfusion accordingly, but it should not happen in general; 3. Intraoperative accidental injury to the main organs: such as accidental entry of the suction tip into the chest cavity and abdominal cavity during the operation. The incidence of such cases is very low; 4, fat tethering: the incidence of such complications is very low, but if they occur, they are more dangerous and need to be actively and strictly rescued. It is generally believed that with wet expansion liposuction, the possibility of such complications is very small; 5, postoperative infection: the infection rate of such surgery in regular hospitals is about 2% to 5%, which mainly depends on the aseptic conditions of the hospital, the operation of the doctor, the physical condition of the patient, the postoperative recovery conditions, whether to reasonably apply antibacterial drugs prophylactically and other factors; 6, postoperative skin flap necrosis: if the surgery If too much subcutaneous fat is sucked out during the surgery, which destroys the blood circulation of the skin, skin blistering or even necrosis may occur, leaving a scar after surgery and affecting the appearance, in this regard, the technical level of the doctor is very important; 7. 8, postoperative wound delayed healing: liposuction wounds are generally a few millimeters, healing is easier, but if the damage is too heavy, infection, fluid accumulation and other factors, there may be delayed healing, and the small scar left after healing is also more obvious; 9, postoperative numbness and abnormal sensation: after liposuction, liposuction area skin sensation is bound to be affected, numbness and abnormal sensation such as occasional pins and needles, ant The numbness and abnormal sensation, such as occasional pins and needles, ants, etc., will be gradually recovered in 1 to 3 months after surgery; 10. Slightly hard texture of the operation area: the texture of the operation area after liposuction is slightly hard compared with that before the operation, which is caused by the formation of subcutaneous fat layer scar and edema and other factors, and can generally recover on its own about 3 months after the operation; 12, serious asymmetry of the liposuction area: this is caused by improper design and operation before the operation, and should be avoided. The main complications of liposuction and its preventive measures as described above, it should be stressed that liposuction is a typical plastic surgery, not a general life cosmetic project, the selection of indications, preoperative preparations, intraoperative operations and postoperative treatment should be carried out strictly, so the regular plastic surgery medical institutions and strictly trained, objective attitude of plastic surgeons is the only correct choice for such patients. In this way, the risks and complications of liposuction can be minimized and the occasional complications can be handled correctly to achieve a good body shape improvement.
