The dose of anesthetic is too small, the patient is likely to have multiple shocks during the operation, these shocks are quite fatal, and a shock coma accidentally occurs and the operation must be stopped immediately, which undoubtedly increases the difficulty.

"Therefore, anesthetics should not be taken in large doses, they can only be injected locally and abandoned!" Chen Hanyu weighed it and began to pour out the ice cubes in the ice machine, and he was going to use the anesthetic effect of traditional Chinese medicine to cooperate with the ice cubes to expand the anesthetic effect to the extreme.

Xu Feng came quickly, he didn't bring a lot of people, and after asking, he learned that it was the hostess of No. 552 who asked for it, so when he came alone, Chen Hanyu was a little surprised.

"Dean Xu!" Chen Hanyu nodded towards the person who was slowly walking towards the door.

"Brother Chen, this is a tricky thing. Xu Feng smiled bitterly and walked over to Chen Hanyu, he put the box in his hand on the operating table, and then spread it out.

Should you give up on tricky things, this is obviously impossible, Chen Hanyu did not give up the word in his dictionary, let alone flinched.

Animal glue is first taken out to heat, the heating time is to be strictly controlled, the time is too short animal glue is soft collapse is not suitable for filling, and too long animal glue will become hard and cracked, so not suitable for filling.

Watching Chen Hanyu roast the animal glue under the alcohol lamp, Xu Feng quietly began to cooperate with Chen Hanyu to take out the anesthetic, and he skillfully put the herbs in the medicine cup and pounded them.

These herbs are for medicinal juices, and the leaves and other residues are of no use.

The ice cubes of the ice machine were taken out, and the reason why the temperature was not kept at a low temperature was to make the temperature of the medicine more suitable for the current situation.

"Dean Xu, I'm going to start the operation, I'm going to bother you here, just configure all the Chinese medicines I need according to the list!" Chen Hanyu said with a smile, these tasks are easy for Xu Feng, the director of the Chinese medicine hospital, and he doesn't need to tell him how to do it.

Chen Hanyu skillfully wrapped the scalpel around the patient's scalp, and he found that there were originally stitches on the scalp, indicating that someone had already used the knife before.

The stitches are very dense, and it should be carried out by a doctor who can do a good job, but it should be because he can't do anything about the occipital bone that he chose to suture again.

"The second suture was a huge challenge for me, and I really didn't know how important it was to take on this job. Chen Hanyu said with a wry smile.

In this way, it was only necessary to use the knife on the basis of the original wound, and Chen Hanyu cut off the entire scalp with almost no difficulty.

Considering that the wound could not be exposed to the air for too long, Chen Hanyu still turned on the sterility instrument in advance, and what he had to do now was to fit the head and fill the animal glue into it.

But now he clearly saw the condition of the patient's cranial cavity, where the occipital bone should have appeared, only a thin membrane remained, and this membrane was well isolated from the cortex, so that the normal brainstem tissue inside would not fly out.

"The one who did this surgery is a master!" Chen Hanyu saw that the stitches around this membrane were actually added the day after tomorrow, and they should be the traces left by the previous one who operated on the patient.

I have to admire this person's handwriting, Chen Hanyu has never seen anyone use such a seemingly non-rigorous method to complete a thing that requires extreme rigour.

"Dean Xu, come and see whose handwriting this is, there are not many people who can make such a thing?" Chen Hanyu glanced at Xu Feng and asked.

"Not much, let's not talk about this kind of operation in Yunfan City, but the number of doctors who dare to open the craniotomy like this is not more than this number!" Xu Feng said and stretched out five fingers, he looked at Chen Hanyu and said, "You Chen Hanyu is one of them!"

Craniotomy has been conquered by modern medicine as early as the last century, not that this operation is difficult, but it is really difficult to ensure absolute safety, and no one dares to bear the risks brought by this operation 100%.

"It's really appalling to say this!" Chen Hanyu smiled bitterly and fixed the prepared animal glue on the outside of the film, he resampled it and began to do simple stitching, leaving a small edge to prevent the harm caused by abrasion.

Because the back of the head does not have any support points, and such a straight pillow is bound to pierce this layer of film, and the force points of the occipital bone are only scattered at the edge, and once the other places are forced, the result is that it begins to collapse from a hollow place in the middle, which is the most difficult problem at present.

"I obviously didn't think about it that much. Chen Hanyu fell into deep thought, just now he didn't expect that there would be such a membrane in the cranial cavity, and now that the last step of his animal glue is about to be placed, it is still too late to change his mind temporarily.

After thinking about it carefully, Chen Hanyu re-sorted out the problem.

"Hou Jin, go and see what it smells like outside this door!" Chen Hanyu frowned unhappily, this smell of burnt paste made him smell very uncomfortable.

Hou Jin quickly ran back, and he told Chen Hanyu that the master of the pastry shop was making cakes outside, but the taste was more unique, so the taste was a little bigger.

"Eggs?" Chen Hanyu asked suspiciously.

"Uh-huh!" Hou Jin didn't know that he was wrong, it was indeed an egg.

A strange idea suddenly popped up in Chen Hanyu's mind, the structure of the egg is the most stable, and there is another similar to the egg, that is, the triangular structure, but it is impossible to use the triangular structure in the back of the head, so this idea was immediately denied, but the egg can indeed be tried.

"I decided to use the egg method to fill the back of my head!" Chen Hanyu made a big decision.

When this decision was spoken, not only Xu Feng, but even Hou Jin looked at him suspiciously, filling it with eggs, isn't it whimsical.

"Brother Chen, are you serious?" Xu Feng asked cautiously, he didn't know where Chen Hanyu's basis was, so it was not easy to ask directly.

Chen Hanyu nodded, he said that he was not joking, but now he needs to find a good angle.

He then looked at Hou Jin and ordered, "Hou Jin, you go to the pastry chef and ask for a basket of eggs, you don't need too much, three or five are enough!"

After waiting for a while, it was the proprietress who brought the eggs, and she walked up to Chen Hanyu in wonder and said, "I'm not good at surgery, but you're the first one to ask for eggs!"
