The main component of ketamine is ketamine hydrochloride, which has an analgesic effect. It is an intravenous general anesthetic that can usually be used for anesthesia before minor operations.

If he hadn't been afraid that the patient would be harmed, Chen Qi would have really wanted to fight poison with poison and poison the cobra directly.

The venomous snake on the screen didn't know whether it was suffering because its head was stuck, or it was struggling because of the pain in the stomach acid environment. Anyway, it was twisted very badly.

Those who are not afraid of snakes don't know, but those who are afraid of snakes are afraid to watch the snakes twist. If someone touches Chen Qi's skin at this time, he will find that it is covered with dense goose bumps.

The clear and calm look on his face is all fucking fake, in order to maintain his demeanor as a people's teacher.

The anesthesiologist quickly retrieved the ketamine needle, and Chen Qi put it into a special syringe. The needle installed at the top of the gastroscope began to prick the venomous snake.

How can cobras be so easy to prick? I'm not a big sow. I can inject with my eyes closed.

Snakes are all slippery and have a thick layer of scales on their body. In addition, the venomous snake is still twisting and turning and cannot be fixed.

So Chen Qi, like Aunt Rong, kept pricking, pricking, pricking with the needle, but couldn't prick the poisonous snake, or the needle slipped away after hitting it.

This made the people operating next to me anxious. They all wanted to go up and inject the poisonous snake themselves, and they all complained that their own dean was stupid.

Master student Zhu Jianwei is from the mountains of Guizhou. He has been dealing with snakes since he was a child. He is not afraid of these cold-blooded animals and he also knows the anatomy of snakes very well.

When he saw that his teacher couldn't prick the poisonous snake after trying it for a long time, he became anxious:

"Teacher Chen, you can't pierce the snake's body with such a short needle. You have to pierce the snake's mouth or anus. These two locations are the weakest."

Snake anus?

The chief surgeon and the doctors next to him were all confused. What is the snake's anus? Where is it? What does it look like?

Zhu Jianwei looked confused when he saw Big Eyes, so he quickly said to the screen:

"Look here, at the tail end of the snake, are there several large scales? Below these scales is the anus?"

Chen Qi and other students all moved closer to the display screen. The display screen in this era was a picture tube TV, and the resolution was not high. In addition, the poisonous snake was twisting around, and everyone looked lonely.

Zhu Jianwei was anxious: "That's it, that's it. You can't see such a big anus. I could clearly see the scales just now."

"Where? Is this it?"

"No, no!"

"here?"

"Oh, you're so stupid! Oh, Teacher Chen, I'm not talking about you!"

Chen Qi was about to vomit blood at this time, and directly handed the gastroscope operating handle to Zhu Jianwei:

"Come on, come on, you do it, you do it, leave professional matters to professionals. You old man from Guizhou knows venomous snakes better. Come and inject its anus. Oh my god, I'm exhausted. My eyes are dizzy."

.”

Zhu Jianwei didn't refuse. He had been practicing endoscopic surgery for half a year, and he had absolutely no problem with basic skills.

Doctors in later generations went to higher-level hospitals to learn gastroscopy, which only lasted half a year or a year at most. Before students like Chen Qi, who had an endoscope in hand and had them practice day and night, they could have left the novice village long ago.

So after Zhu Jianwei took over the operating handle, he immediately laughed:

"Thank you, Teacher Chen, for the opportunity!"

Guan Zelong patted his thigh: "Damn, Jianwei is the first one to get the chance to perform surgery."

The classmates all laughed. Although there was a little envy, their eyes were not really red with jealousy. The drama of workplace drama is quite far away from these students.

After Zhu Jianwei took the operating handle of the endoscope, his eyes were fixed on the display screen, and the needle was ready to be fired at any time.

Just as the venomous snake twisted around and its scales lifted up to reveal the gap between its anus, Zhu Jianwei moved quickly and directly inserted the needle into the venomous snake's anus, and then quickly pushed in the anesthetic.

"Teacher Chen, how much anesthetic should be pushed in?"

"Push it all away, not a drop is left."

When Zhu Jianwei saw his teacher gnashing his teeth, he thought he was vindicating the patient's injustice, so he "viciously" injected all the anesthesia into the snake's body.

"Okay~~~"

Seeing that the anesthesia needle was finally inserted, there was a burst of applause both inside and outside the operating room.

Zhu Jianwei proudly wanted to return the operating handle to Chen Qi, but Chen Qi waved his hand:

"You did a good job. Today's endoscopic surgery is very simple. I will guide you and you will perform the surgery."

Zhu Jianwei was stunned for a moment, and then said ecstatically: "Thank you, Teacher Chen, thank you, Teacher Chen."

Now the other students in the master's class are really a little jealous. This is a great thing to show up in front of professors and major doctors, and he is also the first among his classmates to perform endoscopic surgery.

Who can remember the second highest mountain in the world?

It was a snake after all. An adult-size anesthetic injection was injected into it, and it stopped moving after a while. I don’t know if it was dead or drunk.

The master's students didn't dare to talk much when the teacher was performing the surgery. Now, weren't their classmates performing the surgery? So they all started to chatterbox and kept urging:

"Old Zhu, hurry up, the snake has stopped moving, pull it out quickly!"

"It can't be pulled out. This snake house is too fragile and cannot be clamped by the endoscope!"

"Cut it into sections, you still have to take it out piece by piece."

The classmates were chattering, making Zhu Jianwei's head hurt. After all, he was a newbie and he had no experience.

At this time, Chen Qi silently took out a special ferrule for endoscopes and said, "Use this!"

Condoms are available, but that doesn't mean this surgery can be easily solved. Now I have another headache.

The snake stopped moving, and the ferrule was inserted through the snake's tail. However, due to the limitations of the endoscope, the ferrule could not be tightened. So the surgeon in charge used a little force and the ferrule would loosen, making it impossible to pull the snake out.

What's more important is that the snake's head is stuck by the pylorus, and it can't be pulled out.

what to do?

Master students, you look at me, I look at you, and then we all look at Professor Chen Qi.

There was also a lot of discussion in the multimedia classroom, especially after seeing that the ferrule kept slipping, they had lost confidence in endoscopic surgery.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Zhu Huoyan also signaled his assistant to quickly prepare the operating room. The doctor carried out disinfection work in advance and could accept the operation at any time.

Chen Qi blinked: "Why are you all looking at me? Keep going!"

Zhu Jianwei's face was as red as a monkey's butt: "Teacher Chen, I, I can't pull it out, the snake's head is stuck in the pylorus."

Chen Qi seduced: "The pyloric circular muscle is spasming and contracting tonic. What would you do if you were a doctor?"

Jin Meng was the first to answer: "First we should relieve spasms and relieve muscle tension."

Chen Qi asked: "Then how can we relieve spasm?"

Teng Yuqin raised her hand: "I know, I know, you can use 654-2 injection first."

Chen Qi shook his eyebrows: "It seems that you all know it, why can't you apply it flexibly? Take the medicine quickly."

654-2, also called anisodamine, has obvious peripheral anticholinergic effects. It can resist the contraction of intestinal and bladder smooth muscles and the decrease in blood pressure caused by acetylcholine, and can reduce intestinal tension in the body. The intensity of its effect is similar to that of atropine.

The nurse quickly took out the 654-2 injection, and Zhu Jianwei quickly injected it into the circular muscle next to the pylorus, and the effect was very fast.

In less than 10 minutes, the pyloric ring muscle relaxed.

Chen Qi reminded again: "Just set the trap in the direction of the snake's head, yes, set it a little, move it back a little, move it a little..."

Zhu Jianwei spent a long time in the trap, and he broke into cold sweat visible to the naked eye:

"Teacher Chen, that's not possible. The snake's scales all grow along the way. Now that we have to reverse the car, the scales have turned into reverse scales and we can't pull them out."

Many doctors in the multimedia classroom are discussing:

"Look, I said there are snake scales, so you can't pull them out by pulling them backwards."

"The snake's head is also a bit thicker, and the muscles are not completely relaxed yet, so it will be a bit difficult to pull it out."

"Endoscopes still have limitations. They can see snakes, but they can't remove them."

Chen Qi walked around in the operating room, and then said to a glass bottle on the shelf:

"Bring over the brown bottle."

Jin Meng reacted quickly and ran over immediately. He even looked at the label and his eyes suddenly lit up.

Chen Qi originally wanted to say something, but when he saw Jin Meng's look, he knew that the little girl had guessed the intention, so he smiled and nodded.

Jin Meng gave the brown bottle to Zhu Jianwei:

"Zhu Jianwei, you are so stupid. You don't know how to work around it. The snake's head is thick and big, and the neck is narrow here, so it gets stuck there and cannot move. In addition, the snake scale barbs increase the friction, so let's think

There is a way to reduce the friction. Here, this is a lubricant. After using it, you can move in and out freely."

Oh~~~~

Then the master's students suddenly realized: "Oh, why didn't we think of it? It must be Teacher Chen."

Chen Qi raised his hands and smiled brighter than a chrysanthemum: "How could I be your teacher otherwise, haha."

The application of lubricant and 654-2 needle quickly solved the two biggest problems.

I saw Zhu Jianwei really pulling the poisonous snake out of the pylorus centimeter by centimeter.

Just when everyone was watching anxiously, Zhu Jianwei felt that the resistance in his hands suddenly disappeared, and the snake's head was completely pulled out of the pylorus.
