Su Hongwen came up with this surgical plan has always been considered unbelievable, but why is it unbelievable? It is because he wants to replace the blood supply blood vessels of the fetus with artificial blood vessels, and at the same time block the umbilical arteries and veins, which is equivalent to the child living in Liu Dongmei's uterus, but the nutrients needed are supplied by the blood in the external pump until the child is born at term, which is equivalent to separating Liu Dongmei and the child into two separate individuals, Liu Dongmei's asthma needs medication, and she can rest assured that she can use medication after the operation is completed.

At that time, her blood will not supply nutrients to the child, so she doesn't need to care about the bad impact of the medicine on the child, and the nutrients that the child needs are all supplied by other blood, so that the child will not be underdeveloped due to lack of oxygen, which is also the reason why Su Hongwen needs so much blood for Lang.

Now all the blood collected is the same type of blood of young women, and the reason for using this blood is that these women, whether they have had children or not, have in their blood a special hormone that the fetus needs, which is the main hormone that promotes fetal development, which is not found in the blood of men.

Now it is clear that Liu Dongmei and the child are one, but Su Hongwen used this method to "separate" them and treat them differently, this surgical method is indeed incredible, but it also proves the strength of Su Hongwen's divergent thinking, he is also an earthling, what can he think of, but others can't think of this surgical method?

Su Hongwen has indeed been genetically modified to make him smarter, but his IQ is not to the point of a monster, just smarter than ordinary people. Aren't there billions of people on earth who have an IQ similar to his? The answer is definitely yes, but their divergent thinking is not developed enough, and the education they receive is also different from Su Hongwen, he was taught by the Zhiyuan Star people who are far beyond the earth technology for thousands of years, although this education is not long, but it is enough for Su Hongwen to have a very strong divergent thinking, so that he continues to innovate some new surgical methods in medicine.

The previous surgery has been completed, and now the most difficult thing is to change the umbilical artery vein that supplies the child with nutrients to an artificial artery vein, and you have to block the maternal abdominal artery vein. But if you block it first, the three children will not be able to get oxygen. The three of them have developed slowly due to lack of oxygen, and their bodies are not fully developed yet, even if they block the blood supply like ordinary babies, they will not be able to do anything if they connect the artificial arteries and veins as soon as possible to make timely offerings.

But these three children could die if they cut off the offerings. It's just that their bodies are too fragile. This is also due to lack of oxygen.

However, the arteries and veins of the umbilical cord are not blocked first. Instead, it is not possible to connect the artificial artery and vein first, because the three children only have these two blood vessels for them to feed, and if you want to connect the artificial artery and vein, you have to cut the umbilical artery and vein. How else to connect?

This walked into a dead end, but Su Hongwen came up with a very unique method, he first used a hemostat to lift a section of the umbilical cord, and then a little free, until the two parallel arteries and veins were exposed, at this time he taught the two instruments in his hand to the assistant, and he anesthetized next to Liu Dongmei's abdominal navel, and then used a scalpel to make a small incision, which is the position of the artificial arterioven.

Open this opening and enter the abdominal cavity, Su Hongwen and the nurse wanted to prepare the artificial artery and vein of the uterus and insert it, and punch an eye in the uterus to let the two artificial arteries and veins enter it.

The so-called artificial artery and vein is actually a tube with two pipes, one tube goes to the vein, and the other goes to the artery, this kind of tube is very common and not unusual, but today's tube is a little weird compared with others, the front end was separated by Su Hongwen in advance, and the accounting is to become two tubes, and cut out sharp stubble with scissors.

After this artificial artery and vein entered the uterus, Su Hongwen picked up the hemostat and tweezers and began to continue to free the two blood vessels, this step is a little weird, obviously the arteries and veins in the umbilical cord have been free and leaked in the surgical field, what else is free?

However, those experts in the monitoring room knew that Su Hongwen was dissociating the blood vessel wall and making the blood vessel wall as thin as possible, so as to facilitate the smooth insertion of the front end of the artificial artery and vein.

The blood vessel wall is not thick, unless it is those big blood vessels in the human body, the umbilical artery vein that Su Hongwen peeled off during the operation is not a big blood vessel, so that the blood vessel wall is thinner, and such a thin blood vessel will become thinner, which is very difficult.

Some people say that if you find an artificial arteriovenous tube with hard material, the front end will be eliminated into a sharp stubble and inserted directly, which will not work at all, because this tube will enter the human body and be connected to the blood vessels, and this tube is a foreign body for the human body, which will make the human body have a foreign body rejection reaction.

Foreign body reaction may not be understood by many people what is going on, for example, if you have a very small thorn in your hand, you don't care about it, after a few days you will find that the position of this thorn bulges a small packet, if you pick it up, you will see this small thorn, if you don't pick it up for a while, this small bubble will also break, and the thorn inside will come out with the tissue fluid inside.

This is the foreign body rejection reaction of the human body, the hard tube is there, but this thing is not accepted by the human body, it is okay to use it for a short time, but there will be foreign body rejection reaction after a long time, you must know that the artificial artery and vein of the Lang Dao will stay in Liu Dongmei's stomach for a long time, until the child is born at term, such a long time will definitely have a rejection reaction, and the most difficult one is either the tube falls off, or it causes a serious rejection reaction that threatens the life of Liu Dongmei and the child, both of which can put their mother and son to death.

If you want to avoid this situation, you have to use artificial arteries and veins made of special materials, which will not cause rejection of the human body, but the hardness is not enough, in order to make this artificial artery and vein can be smoothly connected with the blood vessels, Su Hongwen has to choose the most risky peeling off the blood vessel wall.

The umbilical artery and vein are not thick, and they are slightly thicker than the human index finger, which is still the thickness of the two blood vessels superimposed together, and now a single blood vessel is taken out of this can be even thinner, and it is difficult to peel off the blood vessel wall layer by layer with a hemostat on such a thin blood vessel, and the child will be in danger if the blood vessel is ruptured by a slight accident.

There can be no mistakes in this step, so Su Hongwen's movements are very slow, and the hemostat keeps gently clamping something on the blood vessel wall, but you can't see what the hemostat has picked up from the monitor, as if Su Hongwen himself is using the hemostat to clamp the air.

But the actual situation is not like this, Su Hongwen is tearing the blood vessel wall little by little with this slow and light seemingly useless method, this step seems to have no skills, but there are high requirements for the size of the force, the blood vessels may be broken if the force is large, and the force is light There is no effect at all, ordinary people can't grasp the size of this force at all, and only Su Hongwen's genetically modified sensitive hands can master this strength, and he is constantly exploring the toughness and strength of the blood vessel wall with the developed and sensitive nerves in his hands. It is constantly pinching up a layer of blood vessel walls that are thinner than cicada wings.

The people in the monitoring room saw that Su Hongwen was doing this step very hard, and felt that Su Hongwen was doing useless work, as if he was playing, at this time Cai Yufen shouted: "What the hell is he doing?" Isn't that a fool of that? Could it be that he was holding amniotic fluid there? ”

Feng Xu finally couldn't help it, and said unhappily: "If you are talking, give me a mouth." ”

Cai Yufen saw that Feng Xu was so protective of Su Hongwen, and she felt jealous again, but she didn't dare to say anything, she still wanted to come to Anhe Hospital to work, if she offended Feng Xu ruthlessly, don't think about it, she could only be very Su Hongwen in her heart, and she also hated Feng Xu for being blind and appreciating Su Hongwen so much.

Time passed little by little, and after about an hour, Su Hongwen finally stopped his "useless" action, clamped a pipe with a hemostat, and gritted his teeth and ran to the blood vessel wall that he had peeled off and inserted it.

But fortunately, as soon as the pipeline touched the blood vessel, it was inserted as if it did not encounter resistance, and everyone was happy when they saw this scene, Su Hongwen also breathed a sigh of relief, and he did not delay and inserted another pipeline into another blood vessel, and after fixing these two pipelines, Su Hongwen shouted: "Turn on the extracorporeal circulation pump quickly, and the frequency of pumping blood must be the same as the patient's heartbeat." ”

The extracorporeal circulation pump is used to circulate blood for the patient outside the body, but there are requirements for frequency, which must be the same as the number of heartbeats of the patient.

Now the child in Liu Dongmei's belly is more fragile than ordinary people, so the frequency of this blood pumping must be mastered, otherwise it will kill the three little guys.

Watching the blood in the pipeline injected into the child's body, Su Hongwen breathed a sigh of relief, if there was no accident, the operation was basically completed, and he did not delay to quickly fix the artificial arteries, and then block the umbilical arteries.

After getting these done, Su Hongwen didn't rush to withdraw the endoscope, but first asked Miao Sihui to give Liu Dongmei medicine, and he still needed to observe for a while to confirm that Liu Dongmei and the child had nothing to do before he could pull out the endoscope.

The experts and professors in the monitoring room saw that the faces of the experts and professors were excited again, the operation was basically successful now, and the success of this operation means that someone in China has finally created a new surgical method, so that the medical workers in China can face the international counterparts with their chests held up.
