Medical Immortals come from the future

Chapter 221 Preoperative Preparation
The people onlookers were curious when they saw the stretcher carrying a patient for the first time, but they all automatically made way for them.

As the patient entered the Sacred Heart Hall, everyone rushed towards the Sacred Heart Hall. Nan Rumeng also knew what happened, so he asked the guards of the palace to stop the people who came, but the people It was too powerful, and in the end seven or eight of them slipped in. You run a medicine hall, so you can't drive them out.

The three members of the Jin family stood at the door of their own medicine hall, watching this incident seem to be a little miraculous.

Shopkeeper Jin said: "Master, should we also go and see? What if they really saved that man..."

Jin Er Shizu sneered: "How is it possible? Do you really believe that little girl has such a great ability? Let's just watch the fun. It will be just right if someone dies in their medicine hall later. They don't open today. People were put to death on the first day of opening, I see how they can continue to open! With so many eyes watching, who would dare to go to them to see a doctor and buy medicine at that time, even if I have the support of the king of heaven !"

The master of the Jin family looked at the opposite side, but he didn't say a word. After a while, he turned and walked back to his medicine hall, saying: "Go back and wait for the news."

Jin Ershizu patted his sleeves and led the two dog legs in.

Shopkeeper Jin thought for a while, called a little apprentice, whispered a few words, and then saw the little apprentice nodded, ran towards the opposite side quickly, squeezed into the crowd and disappeared.

……

What happened outside is none of Sima Qing's business for the time being.

The patient was carried on a stretcher into a room in the backyard of the Sacre Coeur.

This room is also the "operating room" specially opened up for such emergencies before. Of course, apart from a convenient "operating bed" like the one used for Nan Rumeng's operation last time, there is actually Nothing else, lights?How can there be no power supply?
If you really want to say something different, that is, there are some masks, gloves, sterilized surgical gowns and patient gowns inside. The location is also the best in the entire backyard, and the windows on all sides are well lit. During the day It can satisfy the lighting problem of the operation process, of course, the premise is sunny and some relatively small operations that do not need to be too subtle.

Before, except for Nan Rumeng and Mei Ruotian, everyone else was still wondering what Sima Qing was doing in such a room on purpose.Come to know now, it turned out to be for this purpose, what is it called "operating room".

Although everyone seemed curious, Sima Qing didn't have time to explain to them right now.

She took out several first-aid kits. Apart from some regular items such as medical alcohol, cotton, bandages, and blood pressure monitors, they were surgical instruments used in general operations.Take out all the seven or eight bottles of medical alcohol inside, let Chunxi and Mei Ruotian disinfect the operation area in the room, and then put all the instruments needed for this operation on the plate one by one, and then re-sterilize again.

What I want to talk about is the people who participated in the operation this time.

It is impossible for Sima Qing to be alone in one operation, and compared with Nan Rumeng's last operation, this operation is really nothing.Nan Rumeng is the little witch, and this is the great witch.

So she needs at least two assistants this time. Needless to say, Mei Ruotian must be the first assistant. Not to mention his previous experience, he is also one of these people who knows these surgical instruments.

The second choice is Chunxi. Although she is relatively timid, she has always stayed by her side before. She has occasionally given her science education about the things in the medicine box. Although the silly girl has always been ignorant, But at least I won't feel too strange about these things and what she is going to do, and it's good to stay and wipe her sweat.

For the third option, Sima Qing was thinking about whether she needed it or not, but just to be on the safe side, she decided to keep another one. This person is none other than Nan Rumeng.

To say that Nan Rumeng is better than Chunxi by a little bit. Although she is not a doctor or a nurse, she is like Sima Qing. She is a person who understands modern medicine. Qing would not be surprised by anything she would do, so her psychological quality should be the best among them. If she stays, she can help to be a lead, a thread or something.

Nan Rumeng also agreed, but Xiaoyao Wang was not very happy when he heard it.

He said that Nan Rumeng didn't know medical skills, so why did he involve her?He had watched Sima Qing's surgery on Nan Rumeng last time, and he probably knew what this so-called "surgery" was all about. It was so bloody that even a grown man couldn't stand it, and he didn't want his wife to go through it These.

How did he know that his daughter-in-law's "knowledge" is much more than him, isn't it just surgery?She has seen a lot on TV in her previous life. Although she has never seen it with her own eyes, she will definitely not be more afraid of him than him!On the contrary, she was looking forward to having such a chance to be on the operating table in person, of course, as the standing one, not the lying one.

Fortunately, although Xiaoyao Wang was not very happy, he was still sensible, and he couldn't hold back his own wife. Nan Rumeng convinced him with a few words. After all, manpower is needed now, and human life is more important than heaven!And guarantee, only this time, the next time will not be an example.

Therefore, Sima Qing, Mei Ruotian, Chunxi and Nan Rumeng were the ones who went to the operating table together in the end.

The rest, like Liu Yu, Ling Ruyin, and Imperial Physician Du, can observe outside the operating area, but the patient's family members are not allowed to enter and have to wait outside the operating area.

Originally, Sima Qing wanted to isolate all of them except for the three assistants outside the operating room so that they could not see the process, because she had the idea of ​​sending the patient into the space for several examinations with instruments, but in this situation, There are too many eyes staring at him, so there is no chance for such a living person to disappear out of thin air, so the operation can only be performed directly under the current environment!
Fortunately, Sima Qing was still very confident in her medical skills. Without relying on modern scientific and technological equipment, she relied on experience and knowledge to judge the patient's condition, and then worked out a surgical plan in her mind.

When these preoperative arrangements were made, Sima Qing had already established intravenous access for the patient.

The establishment of intravenous access is the most important measure and fundamental condition for rescuing patients, which can ensure rapid replenishment of blood volume and injection of rescue drugs.

Use 18G and 20G intravenous indwelling trocars to puncture peripheral superficial veins, such as the cephalic vein, great saphenous vein, and external jugular vein.When necessary, the great saphenous vein or internal jugular vein should be punctured for administration, so as to replenish blood volume better and more effectively, and the blood transfusion speed should be adjusted according to heart rate, blood pressure, urine output, etc.

In fact, the most important problem that patients are currently facing is excessive blood loss.

To establish a venous channel, in addition to infusing some anti-inflammatory first aid drugs, the main thing is blood transfusion!

This problem gave Sima Qing a headache. According to the amount of bleeding from the patient, at least 400cc of blood was needed to supplement the entire operation.

But we all know that blood type testing is a more complicated issue.

Simply put, blood type is a genetic trait expressed in the form of blood antigens, divided into three types, abo, and there are special ones.

In a narrow sense, blood type specifically refers to the differences in red blood cell antigens among individuals; but it is now known that in addition to red blood cells, there are also antigenic differences between individuals in white blood cells, platelets and even some plasma proteins.Therefore, blood type in a broad sense should include the differences among individuals in the antigens of blood components.

Usually people's understanding of blood type is often limited to ABO blood type and blood transfusion issues. In fact, blood type has a wide range of practical value in anthropology, genetics, forensic science, clinical medicine and other disciplines, so it has important theory and practice. significance.

Blood types are generally divided into four types: A, B, AB, and O. In addition, there are more than 10 extremely rare blood type systems such as Rh-negative blood type, MNSSU blood type, P blood type, and D-deficient blood type.

Among them, type AB can accept blood transfusion of any blood type, so it is called a universal blood recipient, and type O can export blood to a human body of any blood type, so it is called a universal blood transfusion person or a supernatural blood recipient.

The principle of blood transfusion testing is also complicated.

A system of blood types based on the presence or absence of specific antigens (agglutinogens) A and B on the surface of red blood cells.

If the blood type is incompatible during blood transfusion, the transfused red blood cells will agglutinate, causing vascular obstruction and massive hemolysis in the blood vessel, resulting in serious consequences.

Therefore, blood typing must be done before transfusion.

Under normal circumstances, only people with the same ABO blood type can transfuse each other.

In the emergency situation of lack of the same type of blood source, because the O red blood cell has no agglutinogen, it will not be agglutinated, and it can be transfused to any other blood type. People with type AB have no agglutinin in their serum and can accept any type of red blood cells.

However, when the amount of abnormal blood transfusion is large, the agglutinin in the transfused blood cannot be highly diluted, which may cause the recipient's red blood cells to agglutinate.Therefore, the same type of blood should still be used in massive blood transfusion.

In addition to identifying the ABO blood type before blood transfusion, in addition to the principle of agglutination reaction, the blood of the donor and the recipient is cross-matched to confirm in vitro that the blood of the two is mixed without agglutination before transfusion can be performed to ensure Safety.

Therefore, without glass slides and a microscope, Sima Qing has no way to test whether the blood type is the same as that of the patient, and who can provide blood!

Now, the only way she can think of is blood donation from immediate family members!

That is, let one of Zhang Yuanwai and his wife draw blood to transfuse their son!

Because everyone's blood type is regularly inherited from their parents, so compared with other people who are not related by blood, the probability of his parents' blood type being the same as his is much higher, and the probability of blood clotting is also lower. Relatively much smaller!
