Chapter 75 Anesthetizing Pigs (Please recommend, please collect, thank you!!!)

Seeing experimental animals for the first time, in addition to Lin Xiaobei and Bian Wengang, the other two people, Xu Zhenzhen and Liu Xu, couldn't help but be curious and walked to the cage to watch with interest.

It may be that it is about to make an honorable dedication to medicine, or it may be for the needs of experiments. The pig was washed all over, and it was washed very clean. The stench of the animal is very light and can hardly be smelled.

The pig is also quite docile, lying motionless in the cage, probably because it is full and wants to sleep well.

Just like the ancient prisoners sent off before execution, animals would also be fed a good meal before entering the laboratory, if there is no taboo, to express their gratitude for their dedication.

Liu Xu is like a child going to the zoo, she loves the pig, strokes its belly gently with her hand, and tickles it.The pig became more comfortable, turned over and lay down lazily, enjoying himself very much.

Everyone pushed the pig cage into the laboratory.In order to prevent the pig from running around in the laboratory and damaging the equipment, it should be fully sedated before opening the cage.

Unlike humans, the route of drug administration in animals mostly chooses the marginal ear vein.

This is because their ears are the most unresponsive when they are quiet, their blood vessels are relatively thick, and their ears are large, which is easy to operate.

There are only two people here who have done animal experiments before: Lin Xiaobei and Bian Wengang.

Bian Wengang sat there as stable as Mount Tai, acting as if he had nothing to do with it, so Lin Xiaobei had no choice but to do it himself.

He took the sedative and pulled the pig's ears outside the cage to look for blood vessels.

Catkins continued to gently tickle the pig's belly.This pig is really made comfortable by her, Lin Xiao

Bei didn't resist when he tugged on its ear, and he didn't even struggle when the needle went in.

When Lin Xiaobei was pushing the sedative, he suddenly thought of an idiom: be prepared for danger in times of peace.

This pig enjoys comfort so much, but he doesn't know that this is his last happiness.

After pushing the medicine, the pig soon fell asleep, and Lin Xiaobei patted its head vigorously, but there was no response.

Liu Xu also stopped tickling it, took out a small notebook from her body, and recorded the name and dosage of the drug Lin Xiaobei used to anesthetize the pig.

More than 100 kilograms is not very heavy, but it is also very laborious to get it out of the iron cage.

The old man who followed took out four buckles from his pocket, and put them on the pig's four feet respectively, then took out two iron rods from the iron dragon cart, and passed through the buckles on both sides respectively.

As expected, he is an animal breeder, so experienced.

Liu Xu and Xu Zhenzhen are both girls, no matter how old Bian Wengang is, he is too embarrassed to sit aside, because Director Li Aiguo is resisting.

Four people dragged the pig out of the cage and easily carried it to the experimental table.Lin Xiaobei directed them to work together to lay the pig on its back, and then use bandages to fix the limbs and pig's head.

The old breeder packed up his things, pushed the iron cage and left.

Generally, the large vein is used for pig infusion, but this pig is in a supine position, so it is better to choose the position of the anterior vena cava.

The porcine anterior vena cava is located near the junction of the first rib and the manubrium sternum. Because the left side is close to the phrenic nerve, the right branch is generally used for blood collection and infusion.

Xu Zhenzhen has never given injections to animals, so she doesn't know how to set up an intravenous infusion channel for pigs.

Lin Xiaobei marked the location of the anterior vena cava so that she could barely feel it.

Because it was the first time, Lin Xiaobei demonstrated in person, Xu Zhenzhen and Liu Xu watched carefully, and even Li Aiguo came over to join in the fun.

After the venous channel was established, Lin Xiaobei asked Xu Zhenzhen to prepare the suction device.

This pig has a full stomach and is prone to vomiting and aspiration under the action of anesthetics.Although its final outcome is to give "Ease*" after the experiment is over, it must be guaranteed to be alive during the experiment.

"Liu Xu, have you ever put a gastric tube on a pig?" Lin Xiaobei asked, and then laughed at himself. Isn't this a useless question?

"No, let me try it?" The little girl couldn't help being curious.

Because it was her first operation, Lin Xiaobei first helped her expose the pig's mouth, and the esophagus was obvious.

Start anesthesia after the pig's stomach contents are almost drained.

It was the first time for Liu Xu to intubate an animal's endotrachea, and she was very nervous, so she carefully probed in with the tube.

"It's the same as humans, except that the throat of pigs is higher and the glottis is deeper." Lin Xiaobei instructed her.

Unlike humans, animals rarely have anatomical variation, except for congenital disabilities.But such special cases are very rare, and no ordinary person would bother to raise them unless needed for scientific research.

Another reason is that animals seldom "end old" like humans. Most of them die in young adults, and their physical fitness is in the healthiest period of their lives.

Liu Xu took a deep breath, indicating that she was successfully intubated.

This is indeed the case, because the carbon dioxide waveform on the monitor jumps out very regularly and coherently, like a frame-by-frame animation that keeps moving forward without beginning or end.

The operation can begin now, but Lin Xiaobei pursues better and better anesthesia effects.

Although he is here to cooperate with Li Aiguo and the others, is it not a good opportunity for him to study?
"Would you like to give the pig a nerve block and target injection?" Lin Xiaobei asked Liu Xu.

"Of course I do."

It is very new to give pigs general anesthesia, and it is so interesting and exciting to give them more detailed nerve blocks and target injections.

"But, Mr. Lin, there is no ultrasound here?" She searched around the two rooms and returned empty-handed, and said very dejectedly.

"Who said an ultrasound is needed? Couldn't anesthesia be done without an ultrasound?" Lin Xiaobei educated her annoyedly.

Relying too much on high-tech products does not make a good doctor.

"You mean blind typing?" Liu Xu asked in surprise.

In the Department of Anesthesiology, before doing almost all operations, Mrs. Wenxin must use ultrasound to carefully locate the patients.

It has a good name: No matter how powerful the bow and arrow are, they can't stand up to the sniper rifle, and no matter how good the feeling is, it is not as accurate as the aim.

"if not?"

Lin Xiaobei smiled, could it be possible to bring the ultrasound from the anesthesiology department?

Liu Xu pumped up the local anesthetic, "Okay, you can help me locate it. I really don't understand the distribution of nerves in pigs."

Today, Director Li Aiguo mainly performs appendicitis surgery, so Lin Xiaobei performed celiac ganglion block on this pig.This operation is too difficult for Liuxu. It is almost taught by hand. After the block is completed, select a few target points for injection. Relatively speaking, it is much easier, and Liuxu learns it quickly.

Then Lin Xiaobei taught her to perform a nerve block on the limbs of the pig, using roxime, and the dose was given conservatively, trying to reduce the total dose to avoid local anesthetic poisoning.

"You can start." After finishing, Lin Xiaobei said to the two outsiders and three people standing aside watching.

Now the two teams work together, Li Aiguo leads Bian Wengang to perform appendectomy on pigs, and Xu Zhenzhen is a full-time equipment nurse.

And Lin Xiaobei led Liuxu to practice various blood vessel puncture techniques.

Although it is blind typing, the effect of local anesthetic is still obvious.In the absence of additional intravenous analgesics, when Li Aiguo and the others cut the skin, the indicators on the monitor did not fluctuate significantly.

Lin Xiaobei first taught catkins to thread the pig's central vein to monitor the central venous pressure.Then choose the heel artery catheter in the forelimb to monitor the arterial pressure.Pig's feet are all hoof tissue, as well as gelatinous hooves, and the dorsalis pedis artery is at the root of the hoof.

When doing scientific research, many people use a scalpel to dissect out the animal's heel artery after anesthesia.But Lin Xiaobei doesn't need it, his hand feels very good, and you can see the red spot at the end of the needle with a light prick.

In one step, Xu Zhenzhen on the stage was secretly amazed.

What kind of hands he has!

After Lin Xiaobei put on one forelimb, he handed the needle to Liuxu to pierce the other forelimb.Anyway, it's an experimental animal, and it's a pity to waste it if it doesn't wear white or white.

After completing the puncture of the arteries of the limbs, Lin Xiaobei asked her, "Do you still want to continue the puncture?"

"Think about it!" Liu Xu happily replied, but remembered that she had already put on all she needed to wear, and then asked, "Where else should I wear?"
