Coincidentally, when we interviewed the beauty seekers of liposuction recently, we found that a small number of beauty seekers were instilled with such a (wide) method (accusation)-the less bleeding during liposuction, the higher the skill of the operator; Skilled doctors can even suck out golden yellow pure fat without a trace of blood.
Then the question is, is the level of liposuction really judged by whether there is blood or not? Can a highly skilled doctor really suck out pure fat without a trace of blood when doing liposuction?
Put the conclusion first, no!
First, the doctor's liposuction level can't be judged by the amount of bleeding!
Secondly, liposuction done by any doctor belongs to liposuction mixture, and high-purity fat cells can only be obtained by centrifugation and purification.
Will there be blood in the liposuction mixture?
Yes!
There are two sources of blood during liposuction. One is the blood bank of fat itself. To supply nutrients to fat cells, there must be more or less nourishment from blood.
As we all know, before liposuction, a certain amount of swelling liquid should be injected into the liposuction site. The swelling fluid is actually normal saline plus lidocaine (anesthetic) and epinephrine (hemostatic). You can also understand it as a lubricant to help relieve pain and stop bleeding, separating fat cells from surrounding soft tissues and blood vessels.
In our body, fat is divided into three layers, the layer closest to the skin is subcutaneous fat, and there are many capillaries under the skin. When doing liposuction, you should protect this layer of subcutaneous fat and not damage it. The distribution of our blood vessels is very similar to that of branches. The thinner the blood vessels, the more. On the contrary, the deeper the blood vessels, the less they are, but the thicker they are. Similarly, although the deep blood vessels surrounded by deep fat are thick, they are few in number and easy to avoid. Plastic surgeons with solid anatomical knowledge and rich liposuction experience can easily avoid these large blood vessels. At this time, the bleeding amount of liposuction surgery is only a little loss of fat "nutrition pool".
Liposuction mixture is generally yellow, but it will have a hint of pink. After standing for a period of time, the liposuction mixture will be layered, from top to bottom, which is oil droplets, fat cells and blood water. This is a normal phenomenon, not a poor doctor's skill or liposuction violence.
In addition to the above, liposuction surgery also has a source of bleeding, that is, liposuction needles damage blood vessels during liposuction.
Although this is a very, very rare thing in the hands of plastic surgeons with solid anatomical knowledge and rich liposuction experience in regular medical beauty institutions, I also want to share this knowledge with you.
Careless damage to blood vessels during liposuction may cause fat embolism, that is, free fat cells may enter blood vessels through small wounds on blood vessels. If only a very small amount of fat enters the blood vessels, the protection and defense system of the blood vessels themselves can cope, but if more fat enters the blood vessels, it is likely to block the blood vessels and form vascular embolism. What is even more frightening is that this embolism will be pushed forward by blood and swim in the blood circulation system. Once it reaches the heart or lungs, it may endanger life.
Knowing this, let's go back to the topic itself. Why can't the amount of liposuction bleeding be used as a criterion for doctors' liposuction techniques?
Because it is related to the amount of bleeding, it is not only related to the doctor's liposuction technique and technique, but also related to the preparation work before hand operation-swelling fluid. Liposuction is a blind operation, and doctors can't look directly into the liposuction area. Doctors who have a full understanding of blood vessels and tissue structure will avoid blood vessels through rich clinical experience while deeply liposuction. But many times, if you want to avoid blood vessels better, you have to rely on topical detumescence liquid.
As mentioned above, swelling fluid is actually normal saline plus lidocaine (anesthetic) and adrenaline (hemostatic), in which adrenaline is used to contract blood vessels of skin and mucosa, dilate blood vessels of heart, liver, bones and muscles, and maintain vital signs. Adrenaline constricts blood vessels, which means that the amount of bleeding is reduced. After injection, swelling fluid and fat can be fully mixed to ensure a better effect of constricting blood vessels.
Generally speaking, the ratio of swelling fluid to liposuction is strictly controlled, and the ratio of swelling fluid to liposuction is generally around 1: 1, which needs to be slightly adjusted according to the actual situation of beauty seekers. If there is too little swelling fluid, it will easily become "dry suction" in the later stage of operation, and the damage of "dry suction" to tissues will only increase. In addition, the process of liposuction is actually a "dehydration" process, and the function of swelling liquid is not only to separate fat, but more importantly to "replenish water". "Replenishing water" is also a question asked by universities. The more "hydrating", the more anesthetic and adrenaline in the swelling fluid. But the amount of anesthetic that our body can bear is fixed, and the safe value is 35mg/kg. Once it exceeds this value, toxic reaction may occur, which is one of the reasons why we think that one-time large-dose liposuction is not desirable.
Here, let me summarize the main points for you.
Back to the topic itself, the amount of bleeding in liposuction surgery can not be used as a basis to measure the doctor's liposuction technique, because the factor affecting the amount of bleeding in surgery is swelling fluid. The better the early swelling fluid is combined with the body, the better the effect of adrenaline on vasoconstriction, and the less the possibility of bleeding during operation. At the same time, the expanding liquid is directly proportional to the volume of fat extracted. The more fat to be extracted, the more swelling fluid to be injected in the early stage, and the greater the risk. Finally, I hope that beauty seekers will polish their eyes on the road to beauty. If you want to succeed in liposuction surgery, you not only need to find a plastic surgeon who is proficient in human anatomy, skilled and experienced, but also need to check whether there are anesthesiologists with the same skills and experience in your doctor team.
