Those who undergo liposuction or lipofilling surgery are normal people, and some people think that there is no need to use any medication after surgery. In fact, the postoperative wound looks like a small hole, but there is a large area of trauma under the skin where liposuction is performed, and usually the doctor will recommend wearing a shapewear and applying pressure for at least 2 months. This is because the early application has the effect of compression to stop bleeding, and the continuous pressure in the later stage has a molding effect on the fat tissue remaining under the skin, which can fix the skin fat layer in the correct position, making the skin flatter and recovering faster. Meanwhile, in order to prevent the occurrence of subcutaneous hematoma and infection in the surgical area, antibiotics and hemostatic drugs are usually applied prophylactically within 24 hours after surgery. For larger liposuction areas, antibiotics are applied in the form of intravenous fluids. If it is only a small facial filler procedure, oral antibiotics are sufficient. Inevitably, there will be some postoperative pain, if necessary, you can take oral painkillers, such as Sanli pain, etc.; in the case of a larger operation, hospitalization, the pain is particularly sensitive can be injected intramuscularly or intravenous infusion of the appropriate pain medication. In order to reduce the swelling and recovery faster, you can take oral herbal rhinoceros infusion tablets (elimination), Yunnan Baiyao and so on. The specific amount and method of medication must listen to the doctor’s guidance, can not be unauthorized indiscriminate use of medication, in order to avoid unnecessary danger. Generally the next day after surgery, the doctor will change the medicine, this change does not mean that the use of special drugs, mainly refers to the replacement of clean dressings, clean wounds mean, at the same time, you can observe the postoperative skin swelling, there is no bruising and so on.
