Liposuction plastic surgery can create a perfect body shape. Many beauty seekers may think that liposuction plastic surgery is a minor surgery and feel indifferent. In fact, the risk of liposuction plastic surgery, especially for a large area, is not small. Therefore, when it comes to large area liposuction, we usually take liposuction in stages. The more you do, the better. Safety is the first priority. The more liposuction you do, the more traumatic it is. It’s not just the fat that is extracted by liposuction, but also the blood. Because liposuction is performed under blind vision, the doctor can only rely on experience and the feeling of the hand to operate the movement of the liposuction needle, so it is inevitable that the blood vessels will be injured. The more liposuction is performed, the greater the amount of medication used. The drugs injected into the patient’s body include the anesthetic lidocaine and the vasoconstrictor epinephrine. The latest research proves that more than 90% of the lidocaine injected into the body during liposuction will be absorbed; and after epinephrine is injected, although only less than 1/3 will be absorbed, the concentration of arsenic in the blood will reach several times of normal entry, similar to the concentration of epinephrine in the blood when a car accident occurs. If multiple sites are injected at the same time, the patient will have abnormalities such as elevated blood pressure, tachycardia or even cardiac arrest. Therefore, the amount of swelling solution should be moderate when liposuction is performed. Another point is that the area extracted is too large, and the post-operative feeling will be more unnatural and the activities will be more restricted. Therefore, liposuction is a body sculpting plastic surgery carried out on the premise of safety, not to be greedy and not to save things.
