2. Lidocaine is a local anesthetic commonly used in cases. Each liter of swelling fluid contains 400mg lidocaine with a concentration of 0.04%, which is also the lowest concentration for patients to reduce postoperative anesthesia requirements.
3. Adrenaline may promote vasodilation, which is not conducive to reducing intraoperative bleeding. Therefore, liposuction monopoly should be carried out after injecting swelling liquid for 20 minutes, giving blood vessels a full and firm annual ring. The expanded liquid can gradually combine with fat cells, thus liquefying fat organs for easy suction and control.
As for the injection amount of subcutaneous swelling liquid, it depends on the amount of liquid to be sucked out. When the ratio of them reaches 1: 1, it can not only replenish the lost fluid, but also play a role in hemostasis and analgesia.
5、
6. A large number of cases flashed. When swelling fluid is injected into subcutaneous superficial fat, the safe dose of lidocaine can reach 50mg/kg.
7. Therefore, assuming that the total amount of swelling fluid exceeds 3000ml, the amount of lidocaine contained in each volume will reach the limit of human body. In order to use lidocaine safely and reasonably, surgeons must be fully familiar with the pharmacokinetics of subcutaneous diluted swelling solution, and anesthesiologists should also limit the amount of intravenous infusion during operation. In this way, doctors can suck out a lot of subcutaneous fat in an environment with less bleeding. Generally speaking, they can suck up to 5000 ml of liquid without blood transfusion and fluid replacement.
