On the reader, it was an X-ray of the shoulder blade, and the bullet slightly larger than peanuts was in the center of the shoulder blade, it turned out that Chang Tiejun was suffering a gunshot wound, but when Gu Feng saw that it was this position, his head couldn't help but hurt.

Gu Feng, who has learned a lot of anatomical knowledge, knows that in this location, there are branches of the deep brachial artery, axillary artery, common carotid artery, long thoracic nerve, ulnar nerve, costal nerve, choroid nerve, intertwined and complex.

Although the difficulty of the operation is very high, these experts are all experts in surgery, and any one of them can remove the bullet within an hour, but this is not the most serious problem now.

The bullet has been deeply embedded in the shoulder blade, from the X-ray side view, the bullet has penetrated into the bone, stuck in the scapular fossa, deep into the muscle layer, buried in the vascular nerve vein plexus, to take out the bullet, it is necessary to peel off layer by layer to do it, to open layer by layer, blood loss is inevitable, which is inevitable to transfusion.

Moreover, before this, Chang Tiejun had already lost a lot of blood, and blood transfusion had become the top priority, and if there was no blood transfusion, no one would dare to do such an operation.

The problem lies in this part of the blood transfusion, Chang Tiejun is a Rh-negative blood type patient.

It's well known (uh, there may be some people who don't know, so let's explain it briefly here)

Rh negative blood type is a very rare and rare blood type.

Rh is the first two letters of the foreign name of the rhesus macaque (Rhesus Macacus). In 1940, when Landsteiner and other scientists conducted animal experiments, they found that rhesus macaques and most human red blood cells had antigenic substances of Rh blood group, hence the name. Any red blood cell in the human body that has Rh antigen (also known as D antigen) is called Rh negative. In this way, the four main blood types of red blood cells A, B, O, and AB have been found to be divided into two types: Rh-positive and negative.

According to relevant information, the Rh-positive blood type accounts for about 99.7% of the Han and most ethnic groups in China, and about 90% of individual ethnic minorities. In some ethnic groups abroad, about 85% of people with Rh-positive blood type are present, and among them, about 15% of people with Rh-negative blood type are in European and American Caucasians.

There are four types of Rh-negative blood types: Rh-negative blood type A, Rh-negative blood type B, Rh-negative blood type O, and Rh-negative AB blood group, and their ratios are: Rh3:3:3:1.

Shencheng belongs to Guangzhou Province, where the majority of the population is Han population, there are very few foreign ethnic minorities, and there are even fewer people with Rh negative blood type, and there is not one among 100,000 people, so the reserve amount of all Rh negative blood in the blood bank center in Shencheng is only about 5,000 ML, and the smallest proportion of Rh negative AB blood is only 800 ML.

Unfortunately, Chang Tiejun is the patient with the rarest proportion of Rh-negative AB blood in this proportion, but even more unfortunately, the only 800 ml of Rh-negative AB blood in the blood bank center has been used by another injured person yesterday.

As a result, the difficulty of the operation has also increased, to the point where even a group of experts are helpless.

Gu Feng was also the first two big after listening to the four-eyed expert, although he had been in the laboratory a lot of operations under Yan Xinyue's special guidance, but most of them were some animal specimens, and he didn't have much real human combat, so he could be said to be a raw hand, and when he encountered such force majeure conditions, his eyes were even blacker.

Several experts saw that Gu Feng didn't react at all after hearing about the condition, thinking that he was stupid by such a tricky condition, so they ignored him and continued their discussion.

"Dean Zhao, do you think this will work, let's do a ligation of several large arteries in the front and back so that the blood does not flow, and then start the operation, so that there is no longer a need for blood transfusion?" The four-eyed expert said to the bald Dean Zhao.

Dean Zhao shook his head and asked rhetorically, "Director Sun, you have ligated your blood vessels, how long do you expect to get the bullet out!" ”

"Depending on the position of this bullet, it will take forty minutes to say the least!" Director Four-Eyed Sun replied.

"Stopping the blood supply and oxygen to the surrounding muscle plexus for 40 minutes will not only cause muscle necrosis, but also may cause kidney failure, no, this method will not work!" Another Humpty Dumpty expert immediately vetoed it.

“”

A group of experts were discussing, with different opinions and opinions, but they couldn't think of a good way, at this time, Gu Feng, a small character who had been forgotten by a group of experts, suddenly opened his mouth and said: "If the front doesn't work, then can you try the back?" ”

"Ah?!!h As soon as the word came out, the audience was shocked!

Gu Feng stepped forward and made a gesture to the four-eyed Director Sun, and then pointed to the X-ray photo and said slowly: "The bullet entered from the front chest, passed through the muscle layer, hit the deepest shoulder blade fossa, stuck in the middle, hidden in the dense layers of complex tendons and veins, from the front, it had to be picked up layer by layer, and a large amount of blood loss could not be avoided, but from the back, it became extremely simple, the shoulder and back muscles in the back were the majority, there were no complex neurovascular, as long as the muscle layer was opened, the shoulder blade was exposed, Cut a small shoulder blade along the edge of the bullet, and then don't you take the bullet out? ”

After listening to Gu Feng's words, a group of experts were dumbfounded and half resonated, it turned out that in their eyes, it was an extremely difficult and even invincible operation, but in the eyes of young people who can only be their sons at this age, they have become children who have completed no challenges and no skills.

At this moment, the hearts of a group of experts, professors, and deans are really embarrassed!

"Well, this one, that one seems to have some sense, we can try it from behind!" Dean Zhao, who was thick-skinned, came back to his senses first.

"yes, why can't we think of such a simple solution?" Director Sun also said.

They have been thinking hard about the surgical plan from the front, why haven't they thought of finding another shortcut and starting from the back! A group of experts also looked at Gu Feng one after another, with surprise, admiration, and jealousy in their eyes

Gu Feng didn't say anything more, but he didn't think so, if you want to get it, then why do you want me as the protagonist!

The surgical plan was quickly formulated in the discussion of experts, and it was conservatively estimated that the total blood loss of the entire operation was at least about 50 milliliters, and the maximum was not more than 100 milliliters, and there was no need for blood transfusion.

Everything is ready, it doesn't matter if there is Rh negative AB blood or not, so what are you waiting for, the experts sharpened their knives, and then the operation began.

Although this surgical plan was proposed by Gu Feng, in front of a group of experts, he was not qualified to operate, but they did not drive him out, but let him stay and observe, juniors, you must always be generous and give a chance to learn!

Gu Feng was not disgusted, and stood on the side to watch the performance of a group of experts.

However, an expert is an expert, and although his brain is not very good, he does have a few brushes in his hand.

The main knife was Dean Zhao, who was a little bald and a little weak, and I saw him cut down on Chang Tiejun's shoulder and back, no more, no less, just five centimeters.

The four-eyed Tian Ji Sun Director looked like he had bad eyes, but his hands and feet were also quite sharp, and he picked up a high-frequency electric knife and divided the body tissue by dividing it by two

A few old guys fiddled with each other, and in just a few minutes, the shoulder blade saw that the bullet that came in from the front and stuck in the shoulder blade also showed a little horn, although it was only a little, but it was enough for an expert to locate.

Once the position is set, the next step is to cut the bones, cut the bones together, and then stitch them together, and then you're done, maybe the whole process won't take more than 20 minutes!

However, it was at this time of cutting the bones that the accident happened.
