It has been decided to use the knife for Yu Jungong, and the time is set for three days later.

Huang Yiyun took advantage of the past three days to plan the plan to use the knife for Yu Jungong, as well as the problems that may arise when the knife is used.

So as not to use the knife when you get it, you are in a hurry.

During the past three days, Huang Yiyun did not go out for medical treatment, and was thinking about Yu Jungong's plan for using the knife at home.

Anticipate an emergency situation that may arise when you go under the knife, and if you encounter it, how will you solve it at that time?

After Huang Yiyun thought about the plan to go under the knife, he made an appointment with Lin Chuannian and Imperial Doctor Jiang to discuss the operation.

After all, one person has a short memory and two people are long, although Lin Chuannian and Jiang Imperial Doctor do not have their own abilities, but the two of them have the experience of using the knife many times, the insight and vision, as well as some unique insights, as well as what emergency situations will occur after the knife, the two of them are far more than they have seen.

Sometimes, the two of them can often inspire themselves with a single sentence.

"Is this the tube used for blood transfusions?" Huang Yiyun saw Imperial Doctor Jiang take out two transfusion vessels, she took them and pulled them hard, this transfusion vessels had a toughness and was constantly pulling.

It's just that I don't know what this blood vessel is made of, it is white, and there are sharp needles at both ends of the front and back, which are used to penetrate the human body.

"When the time comes, we will transfuse blood to Yu Jungong, and we will rely on these two blood transfusions." Lin Chuannian nodded.

"How is this a blood transfusion?" Huang Yiyun asked a little confused.

She only remembered that in the case of blood transfusion, the person who donated the blood was packed in a medicine bag after special treatment, and if the blood transfusion was to be used, it seemed to be directly injected into the human body like a drip.

In ancient times, there were no such instruments and techniques, but Huang Yiyun looked at the needles at both ends of the blood vessel.

"One person inserts one end of the blood vessel, and one person inserts the other end, both of which are inserted into the end of the arm blood vessel!" Jiang Yuyi said.

By the way, the location of the blood transfusion was also compared.

The blood transfusion is located in the blood vessel of the elbow joint.

"Dr. Huang, this is not a blood transfusion, I haven't used a knife! I haven't seen a blood transfusion either.

However, this blood transfusion is also particular, it cannot be all transfused at the same height, the blood transfusion person needs to be higher than the position of the transfused person, and the two sides will insert the transfusion vessel, and the blood in the transfused person's body will slowly enter the transfused person's body from the body. When Lin Chuannian saw Huang Yiyun asking, he knew that she had never used a knife on the person who wanted a blood transfusion, nor had she seen a blood transfusion.

"I see?" Huang Yiyun heard Lin Chuannian explain the principle of blood transfusion, she understood and nodded.

The position of the transfused person should be higher than the position of the transfused person, and then the tube is inserted, the transfusion vessel is lowered, and the person lying in the high position will have the pressure in the body higher, and then the blood in the body will slowly flow out, forming a phenomenon of water flowing to a lower place.

"What about the speed of the blood output, if it is too slow, these two transfusion blood vessels alone will not work, in addition to the two arms, in addition to the blood transfusion, in fact, there is also a large blood vessel in the foot, which can also be used for blood transfusion." Huang Yiyun thought of this, and she hurriedly asked.

Because when the time comes, he will cut the blood vessels connected to Yu Jungong's brain, and he will need to bleed heavily, and the congestion of the blocked blood vessels in his body will inevitably bleed at that time, Huang Yiyun is afraid that the speed of blood transfusion will be too slow, and it will be bad at that time.

"The speed of blood transfusion is not fast, as for whether it is slow or not, it is difficult for us to describe it now, you need Huang Imperial Doctor to see it yourself before you can get the results.

After all, it was Imperial Doctor Huang who used the knife this time, and we didn't have such a dangerous operation this time, so it is unknown how fast the blood will flow out of Yu Jungong's body and whether the speed of blood transfusion can keep up. Imperial Doctor Jiang shook his head and said.

"If the blood vessels in the feet can also be transfused, there are four blood transfusions in it, it should be about the same, and, when the time comes, we will first let people transfuse blood to Yu Jungong, let Yiyun you see the speed of blood transfusion, you are calculating.

If you transfuse blood first, you can first ensure that the blood in Yujun Gong's body is sufficient, and enough blood is stored, so that it is convenient for you to use the knife at that time. Lin Chuannian thought for a while.

"Dr. Lin is a good idea, just do it." Huang Yiyun nodded with bright eyes.

"That's it, then I'll go to the imperial hospital to take out two blood vessels." Imperial Doctor Jiang also followed.

Huang Yiyun and the three of them discussed the steps of the knife in detail, and after the manpower and the prescription to be drunk were also discussed, Huang Yiyun said goodbye and left.

The day before waiting for the Duke of Yu County to move the knife, Huang Yiyun came to the Yu Mansion to check the pulse of the Duke of Yu County and check his situation.

And let him not eat that day, just drink some soup and water, and see that everything is ready, just wait for tomorrow to come.

This knife operation is the most dangerous, difficult and exciting one in Huang Yiyun's history.

At night, Huang Yiyun actually had insomnia and couldn't sleep.

In desperation, Huang Yiyun lit incense to help him sleep.

What surprised Huang Yiyun was that the calming incense he extracted was so good, not only did he fall asleep in a short time, he had no dreams all night, and slept until dawn.

If it weren't for Huang Yiyun's heart to remember that she was going to use the knife for Yu Jungong today, she wouldn't have woken up so early.

When she woke up from this night, Huang Yiyun's spirit reached its peak, she was full of confidence and strength.

After eating breakfast, Huang Congjiang personally sent Huang Yiyun to Yu's house.

........。

"Wechen has seen His Royal Highness the Prince." Huang Yiyun came to the Yu family, but he didn't expect the prince to come to the Yu family, seeing him like this, he was ordered by the emperor, and he was waiting for himself to finish using the knife for Yu Jungong, to see if Yu Jungong could survive, and to go back to Emperor Ming Xuan.

As for Lin Chuannian, Imperial Doctor Jiang, Jiang Yan, and Doctor Xiao, they had already arrived, and they arrived three quarters of an hour earlier than the agreed time, so it seemed that they were also in a calm mood or worried about something, so they came to Yufu early.

"Imperial Doctor Huang is exempt from courtesy, and today he will use the knife for Yu Jungong, but please ask Imperial Doctor Huang.

The Huang Imperial Doctor has already arrived, and everything has been prepared, can you use the knife for Yu Jungong now. His Royal Highness the Crown Prince gave Huang Yiyun a handful.

"Naturally, you can." Huang Yiyun nodded and replied.

Subsequently, Huang Yiyun and his entourage went to the main house of Yu Jungong.
