You just pretend

On the video reader, there is an X-ray photo of the shoulder blade. The bullet slightly larger than peanuts is in the center of the shoulder hole. It turns out that Chang Tiejun suffered a gunshot wound, but when Gu Feng saw that it was in this position, his head couldn't help but feel pain.

Gu Feng, who has learned a lot of anatomical knowledge, knows that at this location, there are deep brachial artery, axillary artery, branches of common carotid artery, long thoracic nerves, ulnar nerves, ribs nerves... The vein nerves are intertwined and intersected. If you do an elastic surgery in this place, if you are not careful, you will cut an artery or a nerve, which may cause irreversible consequences.

Although the operation of bullet removal is very difficult, these experts are all authoritative surgical operations. Any one can remove the bullet within an hour. However, the most serious problem now is not this.

The bullet is already deep in the scapula. When viewed from the X-ray lateral film, the bullet has been penetrated into the bones and is stuck in the scapula, penetrated deep into the muscle layer, buried in the vascular nerve veins. If the bullet is to be removed, it must be peeled off to achieve it. If it is opened, blood loss is inevitable, and blood transfusion is inevitable.

Besides, before this, Chang Tiejun had lost a lot of blood, and blood transfusion became the top priority. If he did not have blood transfusion, no one would dare to perform such a surgery.

The problem lies in the blood transfusion process. Chang Tiejun is a patient with RH-negative blood type.

As we all know, rh yin blood type is a very rare and rare blood type.

rh is the first two letters of the foreign name of rhesus macacus. When scientists such as Landsteiner conducted animal experiments in 1940, they found that rh blood type antigens on rh monkeys and most humans' red blood cells, so they were named. Anyone with rh antigen (also known as d antigen) on the red blood cells in human blood is called rh negative. This makes people with the four main blood types of red blood cells that have been discovered, a, b, o and ab, divided into two into rh positive and negative.

According to relevant information, rh-positive blood type accounts for about 997% of the Han and most ethnic groups in my country, and about 90% of individual ethnic minorities. Among some ethnic groups abroad, rh-positive blood type is about 85%, of which in European and American white people, rh-negative blood type accounts for about 15%.

The rh-negative blood types are divided into four types: rh-negative type A blood, rh-negative type B blood, rh-negative type O blood, and rh-negative ab blood. Their ratios are: rh3:3:3:1.

Shenzhen City belongs to Guangzhou Province. The vast majority of the population here is Han nationality, with very few foreign ethnic minorities, and even fewer people with RH-negative blood type, not one out of 100,000 people. Therefore, the reserve amount of RH-negative blood in the center of the blood bank in Shenzhen City is only about 5,000 ml, and the smallest proportion of RH-negative A-type blood type is only 800 ml.

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

As a result, the difficulty of the operation has increased so much that a group of experts are helpless.

After listening to the four-eye expert's story, Gu Feng was also one of the first two. Although he had already put a lot of surgery in the laboratory under Yan Xinyue's special guidance, most of them were animal specimens. He didn't have much real human physical combat, so he could have been said to be a newbie. In addition, he encountered such force majeure conditions, and his eyes turned black.

Several experts saw that Gu Feng had no reaction after hearing about his illness. They thought he was shocked by such a difficult condition, so they ignored him and continued their discussion.

"Director Zhao, do you think this is OK? Let's ligate a few large arteries in the front and back, so that the blood is not flowing, and then the surgery is started. Isn't there any more blood transfusions?" The four-eyed expert said to the bald Dean Zhao.

President Zhao shook his head and asked back: "Director Sun, you have ligated your blood vessels. How long does it take to remove the bullet!"

"It will take at least forty minutes to see the position of this bullet!" Director Sun, Four-eyed Eyes, replied.

"Stop supplying blood and oxygen to the surrounding muscle plexus forty minutes will not only cause muscle necrosis, but may also cause kidney failure. If not, this method will not work!" Another short and fat expert immediately rejected it.

“…”

A group of experts were discussing each other in a row, with different opinions and different opinions, but they could not think of a good way. At this moment, Gu Feng, a small character who had been forgotten by a group of experts, suddenly opened his mouth and said, "If the front does not work, can you try the back?"

"Ah?!!" After the words were spoken, everyone was shocked!

Gu Feng walked up and asked Director Sun to lean against the four-eyed eyes, then pointed to the x-ray photo and said slowly: "The bullet penetrated from the front chest, passed through the muscle layer, hit the deepest shoulder hole, stuck in the middle, hidden in the dense and complex duct ducts. When the surgery comes from the front, it needs to be opened layer by layer, and a large amount of blood loss cannot be avoided. However, when the surgery comes from the back, it becomes extremely simple. The shoulder and back muscles behind it are mostly there, and there are no complicated nerve blood vessels. As long as the muscle layer is opened, the scapula is exposed, and a small piece of shoulder blade is cut along the edge of the bullet, will it be taken out?"

After listening to Gu Feng's words, a group of experts were dumbfounded and couldn't come back to their senses. It turned out that in their eyes it was a very difficult and even invincible operation. At this age, young people who could only be their sons had become children without challenges and skills.

At this moment, the experts, professors and deans of a group of experts, professors and deans were so sad!

"Well, this guy, what he said seems to make 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 method?" Director Sun from Glasses also interfered.

They have been thinking hard about the surgical plan that started from the front, but why have they never thought of taking another shortcut and starting from the back! A group of experts also looked at Gu Feng, with surprise, admiration, and jealousy in their eyes... Gu Feng didn't say anything else, but he didn't agree. If you want to get it, why do you want me, the protagonist?

The surgical plan was quickly formulated in the discussions of experts. Conservative estimates were that the total blood loss of the entire operation was at least about fifty milliliters and the maximum was no more than one hundred milliliters, so there was no need for blood transfusions.

Everything is ready. It doesn’t matter whether there is RH negative ab blood or not. So what are you waiting for? Experts sharpen the knife and then start the surgery.

Although this surgery was proposed by Gu Feng, he was not qualified to take it in front of a group of experts, but they did not drive him out like he was, but asked him to stay and observe. As juniors, you must be more generous and give him a learning opportunity!

Gu Feng didn't dislike it and stood by and watched the performance of a group of experts.

However, experts are experts. Although their brains are not very good, they do have a few brushes on their hands.

The principal was Dean Zhao, who had a little bald head and a little weak kidney. He saw him slashing Chang Tiejun's shoulders, no more or less, just five centimeters.

The four-eyed Frog Director Sun seemed to have bad eyes, but his hands and feet were quite neat. He picked up the high-frequency electric knife and separated the body tissues in a few seconds... Several old guys fiddled with each other. In just a few minutes, the scapula saw the bullet shot in from the front and stuck on the scapula, and even though it was only a little bit, it was enough for an expert to locate it.

After setting the position, the next thing is to cut the bones, cut the bones together and sew them together, and then the task is done. Maybe the whole process will not take twenty minutes!

However, it was the time when the bone was cut, and an accident happened.
Chapter completed!
