Candidates who do not know much about liposuction may be worried about loose skin after liposuction. In fact, liposuction is not about extracting fat in one place, but nowadays most of them use circumferential suction, so candidates do not need to worry too much. However, any surgery may have some complications, and of course liposuction is no exception. 1.Local complications include: bleeding and hematoma, seroma, abnormal skin sensation, skin necrosis, infection, insufficient liposuction and excessive liposuction, asymmetry and unevenness, skin laxity, accidental injury of abdominal wall organs and local skin color change. 2, systemic complications include: fat embolism and fat embolism syndrome, venous thrombosis and pulmonary embolism, fluid imbalance and pulmonary edema and lidocaine toxicity. These complications seem terrible, regular hospitals through the physician’s standardized operation can avoid this risk as much as possible. 1, from the “liposuction surgery” (1) routine sterilization, laying sterile sheets, so that the entire operation in a sterile environment to avoid infection. (2) The surgical area is injected evenly with swelling solution, first injecting and infiltrating the deep layer, then infiltrating the shallow layer, so that the liposuction area has an orange peel-like appearance. And when injecting the swelling solution, strive to be smooth and even to avoid the occurrence of unevenness after suction due to uneven injection of swelling solution. (3) Insert the suction needle into the deep subcutaneous fat tissue through the skin incision or puncture hole, and use the “piston-like” reciprocating motion to suction evenly from deep to shallow layer by layer and area by area. When suctioning, not only should pay attention to observe the suction mixture, but also should always judge the condition of the remaining subcutaneous adipose tissue, including the thickness, symmetry, whether the skin surface is flat, etc., if there are defects at any time to correct. (4) Repeated and repetitive suction at a certain point is strictly prohibited. (5) After the end of suction, squeeze the suction area in a circular motion to eliminate the accumulation of fluid under the skin. 2, from the “liposuction surgery postoperative treatment” (1) local treatment: postoperative wear elastic clothing continuous pressure for 48 hours, change the dressing. If drainage is placed, pull out the drainage strip and continue to wear elastic garment with pressure. Remove the stitches in 7~10 days after surgery and wear elastic garment for 3~6 months. (2) If the liposuction range is wide and the amount of fat sucked out is more than 2000ml, it is advisable to replenish fluids appropriately and take oral antimicrobial drugs for 3 days, and stay in the hospital for observation for 2~3 days if necessary. Through the above explanation, it is easy to see that to try to avoid the risk of liposuction, it is crucial to choose a regular hospital.
