Fat aspiration has been quietly emerging in the national cosmetic surgery institutions for several spring and autumn, which is undoubtedly the majority of obesity and focus on physical beauty friends of the gospel, this method due to the pain is small, the post-operative immediate effect is remarkable, especially the rebound rate is low, safe and reliable, has been increasingly recognized and accepted. Here is a brief answer to some of the problems and countermeasures encountered by friends after surgery. At present, most of the commonly used methods are wet expansion liposuction, of which there are two methods: ultrasonic fat shredding and vacuum negative pressure liposuction. The so-called wet liposuction is to inject “expansion fluid” including saline, local anesthetic and other drugs into the subcutaneous fat layer to make it expand and increase the pressure, and then the fat particles (cells) together with the expansion fluid will be Suction, because the specific gravity of fat is lighter than water, so the pure fat being sucked out floats in the upper layer of liquid, so that the local accumulation of fat disappears and beautiful curves are recreated, but it does not help much to reduce weight, after the operation, in order to drain the residual subcutaneous fluid fully and smoothly. Dressing, elastic bandage or elastic lap band infiltration can be placed around it clean absorbent sanitary napkin or skim cotton, or to the institution where the surgery to find the doctor to change the dressing, must not be loosened and replaced by themselves, so as not to contaminate the operating area or improperly wrapped affect plasticity. After the drainage tube is removed, the dressing should be tightly wrapped to facilitate the skin and deep tissues to be close together and reduce the generation of cavities. Some subcutaneous bruises and skin unevenness may occur, especially in the lower extremities (thighs and calves) within 7-10 days after liposuction drainage removal should reduce activities, elevate the lower extremities to reduce the cause of calf and foot swelling, subcutaneous bruises and even mild skin pigmentation is not terrible, generally 3-6 months with subcutaneous sensory numbness and unevenness gradually recovered and disappear, the majority of “Big belly” friends skin elasticity can be self-retraction, with strict wearing elastic pants, elastic belly band to help shape so that you can get the body shape satisfied. Only individual older, poor skin elasticity and obese, sagging skin patients need to perform abdominoplasty in the second stage to remove part of the excess skin, even so it greatly reduces the risk of multiple complications of direct abdominoplasty. In addition, liposuction should routinely take some oral antimicrobial agents to prevent the occurrence of infection, do not bathe until the drainage opening is removed to prevent unclean water from entering the wound, and wear some loose and easy to take off clothes, etc. is also to be noted. Within half a year after surgery, there may be occasional itching, pins and needles, mosquitoes, etc. These are normal phenomena of tissue healing, the success of surgery is the key to cooperation between doctors and patients. Therefore, autumn, winter and early spring are the three golden seasons for liposuction.
