On the reader, it was an X-ray photo of the shoulder blade, and the bullet slightly larger than peanuts was in the center of the shoulder blade.

Chen Ling, 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, and costal nerve...... The choroid nerves are intertwined and intertwined, and if you are not careful, you will cut an artery or a nerve, which is very likely to cause irreversible consequences.

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, it is 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 transfuse.

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 blood transfusion, Chang Tiejun is an RH-negative blood type patient.

As everyone knows...... (Well, there may be some people who don't know, so let's explain it briefly here)

The rh negative blood type is a very rare and rare blood type.

RH is the first two letters of the rhesus macaque's foreign name. In 1940, when Landsteiner and other scientists conducted animal experiments, they found that rhesus monkeys and most human red blood cells had antigenic substances of rh blood group, hence the name. Any RH antigen (also known as D antigen) on the red blood cells of the human body is called RH negative. As a result, 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 about 15% of them are Rh-negative people in Europe and the United States.

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, 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 5,000ml, and the least proportion of Rh-negative AB blood is only 800ml.

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.

Chen Ling is also a head two after listening to the four-eyed expert, although he has been in the laboratory a lot of operations under the special guidance of Yan Xinyue, but most of them are some animal specimens, and he doesn't have much real human combat with Ben, so he can be said to be a raw hand, plus he encountered such force majeure conditions, then his eyes are even blacker.

Seeing that Chen Ling didn't react at all after hearing about the condition, several experts thought 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 make a ligation of several large arteries in the front and back to stop the blood flowing, and then start the operation, so that there is no longer a need for blood transfusion?" said the four-eyed expert 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 would take forty minutes to say the least!" replied Director Four-Eyed Sun.

"Forty minutes of stopping the blood supply and oxygen to the surrounding plexus will not only cause muscle necrosis, but also cause kidney failure, no, this method will not work!" Another short and fat expert immediately vetoed.

“......”

A group of experts was discussing, with different opinions and opinions, but they couldn't think of a good way, at this time, Chen Ling, 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!

Chen Ling 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 enters from the front chest, passes through the muscle layer, hits the deepest shoulder blade fossa, gets stuck in the middle, hides in the dense layers of complex tendons and veins, and the knife from the front has to be peeled off layer by layer, and a large amount of blood loss cannot be avoided, but the knife from the back becomes extremely simple, the shoulder and back muscles are the majority, there is no complex nerve and blood vessels, as long as the muscle layer is opened, the shoulder blade is exposed, and a small piece of the shoulder blade is cut along the edge of the bullet, so don't you take the bullet out?"

After listening to Chen Ling's words, a group of experts were dumbfounded and half resounded, 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, who said that seems to have some truth, we can try to come from behind!" Dean Zhao, who was thick-skinned, came back to his senses first.

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

They had been thinking hard about the surgical plan to start from the front, why didn't they think of finding another shortcut and starting from behind! A group of experts also looked at Chen Ling one after another, with surprise, admiration, and jealousy in their eyes......

Chen Ling 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 Huo Huo sharpened his knife, and then the operation began.

Although this surgical plan was proposed by Chen Ling, in front of a group of experts, he was not qualified to operate, but they did not drive him out, but asked him to stay and observe.

Chen Ling was not disgusted, and stood aside 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 neat, 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.
