Fat filler embolization, a risk that is well known to the general public due to its emergence in the last two years of fat fillers that have led to the death of candidates. Very serious complications can occur after lipofilling embolization. Minor ones such as problems with eye vision and localized tissue necrosis, while pulmonary embolism and cerebral embolism can be life-threatening. For fat embolism, in terms of regular hospitals, the incidence is actually relatively low. However, due to the fat filling boom in recent years, many organizations and many beauty salons are doing what they can and cannot do, and some beauty seekers have even lost their lives as a result. For fat embolism, it is actually fat injected into the blood vessels. For its prevention, the first point to mention first is anesthesia. Some doctors think that local anesthesia is good, local anesthetics plus parathormone can make the blood vessels constricted, and the chance of insertion will be smaller after the blood vessels become thinner. However, I emphasize that fat filling needs to be done with general anesthesia. If you inject local anesthesia, the amount of filler, the symmetry of the left and right, fat uniformity, can not be reasonably grasp, general anesthesia can be more intuitive. Secondly, after local anesthesia, the blood vessels are fixed, while under general anesthesia the blood vessel wall is sliding, a very full state, a push will go, coupled with the needle is blunt, can greatly reduce the damage to the blood vessels as well as the chance of bruising. The second point is that lipofilling must be injected using a receding needle. When injecting, first open the tunnel, separate a very good cavity, in the case of not injecting, with the needle must be a little bit divided. When injecting, back off the needle injection, one milliliter divided into 60 times to push, slowly, the effect is better and safer. The third point, if the blood vessels are encountered during injection, we must carry out local compression. In the bleeding area, stop filling in time. Because there is a negative pressure in the vein, even if the fat is not pushed into the blood vessels, it is very easy to cause local embolism after being sucked into the blood vessels because the fat contains oil droplets and small particles. Fourth, the amount of injection should not be too large, the range of injection should not be too large, the injection should be loosely injected, if the pressure is too large, the fat droplets and fat particles will be pressed into the blood vessels, it is possible to produce the symptoms of embolism, I hope it can help my friends who are concerned about my doctor.
