Chapter 154: Especially You

Why me?

Tu Yu was very unconvinced, the store alone was not to praise the twenty criticisms who could accept it, but because of what had just happened, he didn't dare to refute, nodded obediently, and responded: "Yes!." ”

Lu Ning was quite satisfied, and continued: "Next, repeat the steps just now, put the needle forceps in the middle of the two wires, and wrap the long end around the needle forceps, yes, just go around a circle, the needle forceps clamp the short end, pull tight, don't pull the line upwards, and then tie one or two, so that the knot is good-looking, square, and will not loosen." ”

Li Tingxuan saw that it was called a concentrated attention!

It turns out that knots should be tied like this, and you need to use needle holding pliers!

He got it!

Lu Ning used simple intermittent sutures to close a five-centimeter-long wound, put down the instrument and said, "Isn't it very simple to look at?" ”

No one dared to say "yes" and all shook their heads.

"You have to remember that surgical suturing is not as simple as you seem, and there is a lot of knowledge in it! This simple intermittent stitching is legal, and you can't master it well without a lot of practice! ”

The five nodded in unison: they got it!

After the painful lesson just now, I don't know that there are ghosts!

"Do you want to practice it yourself, or do you want me to show you how to sew next?" Lu Ning asked.

Li Tingxuan thought about both, so he looked at Doctor Li, of course Doctor Li wanted to see the demonstration!

With his current hand, it must take a lot of effort to practice simple intermittent suturing well, so when will he see the next kind of suturing!

He said, "Ah Ning, you better show us again!" ”

Others have no opinion, and of course, there is one opinion that they dare not express.

Seeing them like this, Lu Ning nodded, and said to Doctor Li, "Then you can introduce the continuous sewing method again." ”

"Huh!" Doctor Li responded, hurriedly began to flip through the book, found the corresponding position, took the book far away, squinted his eyes, and hurriedly read: "Continuous suture method, is the most commonly used suture method for suturing cuts, knotting after the first stitch is sutured, and then the entire wound is sutured with the thread, and the stitch before the end is pulled out and left on the opposite side to form a double thread and a knot with the heavy thread tail." ”

"I'll do it now, and you have to watch it carefully." Lu Ning said, picking up the needle holders and toothed forceps again.

"Okay!" Everyone didn't dare not take a serious look, if it weren't for the fear of blocking Lu Ning's relationship and being scolded, they would have gotten close one by one.

"Continuous suture is also a simple suture method, so in the same way, 90 ° angle, both sides of the needle in and out of the needle should be maintained at a 90 ° angle, the same way, surgical knot, this sheep intestine is very expensive, pay attention to saving, this short end should not be left long, so as not to the back of the thread is not enough to suture the wound, especially you. Li Qigongzi! ”

Li Tingxuan: "......"

"Okay." He said with a smirk, secretly rolling his eyes.

Lu Ning didn't see it, and continued to move his hands: "The surgical knot is the same, continuous suture as the name suggests is that there is no need to cut the thread, but for the beauty of the wound, the distance between the needle and the needle should be evenly proportioned when we suture, and the stitch and the stitch and the skin edge should keep the same distance from each other. ”

"Of course, I'm saying it's early, and you definitely can't do it now, but this is what I expect from you, and it's your ultimate goal, you know?"

Everyone: "Yes! ”

"This kind of suture method must be at a 90° angle to the needle and keep a symmetrical distance, so that the skin will turn outward, and if you insert the needle too far each time, or the needle is too shallow, the skin will turn inward, so that the wound will not heal properly."

"In addition, it should be noted that the suture must be pulled tightly enough, so that the skin margins on both sides will contact and come together, but if the suture is pulled too tightly, it will cause ischemia and leave a bad scar, so how to grasp this degree is what you have to do in the future."

"Finally, make a simple needle insertion at the end, making sure that there is enough tension on the sutures throughout the wound, and then tie a surgical knot at the end."

At the end of Lu Ning's demonstration, looking at their expressions as if they understood or not, she encouraged: "You don't need to be too nervous, study surgery, the most important thing is to connect, isn't there a saying, who can make perfect, it's not very difficult, I believe, you can." ”

Five: "Hehe." ”

Looking at something that is not difficult, only the person who operates it knows how difficult it is to operate!

"These two types of sutures are relatively common, and they can generally be used for trauma, and there are also those suitable for internal sutures, that is, the sutures of the viscera after the abdomen, but for you now, these two types of sutures are enough."

Lu Ning continued: "So I will teach the other sewing method in the future, you will master these two first, the first three days, first use bananas to practice, three days later, well, use pork, other meat with skin is also fine, okay, free practice, if you don't understand, just ask." ”

"Yes!"

The five of them quickly returned to their positions, and picked up the needle forceps and toothed tweezers with their hands, although they knew that they could not be able to suture perfectly, but in their hearts, they must feel that they were not bad, and one day they could impress Lu Ning!

Lu Ning was on the podium at the top of the class, holding a charcoal pen and starting to prepare for class.

Suturing is only a very basic course in surgery, and they have a lot to learn, but the time is limited, and what Lu Ning has to do now is fixed-point teaching.

What kind of military doctors are needed on the battlefield, Lu Ning will train them.

Soldiers who could not be saved by one blow also said that broken hands and feet, external injuries, internal injuries, infections, fevers, and erosion of wounds were all common injuries.

Fortunately, there were no hot weapons such as forced shells in ancient times, and relatively speaking, the danger of ancient wars was much lower than that of modern wars, but now that medical conditions are limited, the mortality rate of soldiers is still high.

Ninety-nine points of the 99.999 percent are complications caused by inflammation, which is a headache for Lu Ning.

The cultivation of penicillin is not easy, even if every soldier is not allergic, but so many soldiers, the penicillin she cultivated is still not enough!

It seems that this will have to be discussed with Daddy to see if it can be expanded.

Ah!

His thoughts drifted away, and Lu Ning came back to his senses and drew a diagram of the structure of the human body with charcoal.

Lu Ning also gave them such a lesson, but it was all words, far less intuitive than the pictures, because the next course will teach intramuscular injection and intravenous injection, and it is better to popularize it with the human structure.

Thinking of injection, Lu Ning's brain is buzzing, modern people are used to using disposable needles, and now the needles are made of iron, how expensive iron is!

She didn't have the luxury of throwing one away!

So they all continued to use after sterilization, although she knew that it was not in accordance with the regulations, but she ...... Poor!

Now I have to raise five more people, tsk, I regret that I didn't have a hand tuition fee at the beginning.

Ah, yes, this needle is not enough, I really waited for the war to start preparing, and the mosquitoes are sleeping!

So, I still have to find my father.

Daddy is omnipotent, and he is, and he is.

"Ahh Let's take a book

I don't know how long it took, Li Tingxuan stretched out his hand and stood up, feeling a sore back, his desktop was already half a table of bananas, and he took the most satisfactory one to Lu Ning.

"Not bad." Lu Ning looked at the uneven stitches, sometimes loose, sometimes tight sutures, and even the surgical knots were crooked, but Li Qigongzi said that this was his most successful suture, so Lu Ning encouraged him: "Come on, strive for better next time!" ”

"Okay!" Li Tingxuan happily went back.

Jiang Ji saw Li Tingxuan go up and down, and also took his "homework" up, waiting for the teacher's evaluation with a worried face.

Lu Ning: "...... Better than last time, come on, you are the smallest, there is a lot of room for upside! ”

Then came Tu Yu, Tu Peng, and Doctor Li......

Lu Ning thought about it for a while, she remembered that she didn't say that she had to hand in her homework, why are these students so self-conscious?

Although she was also very pleased, but at the same time she was also very congested, maybe she had never brought an apprentice, or she was used to seeing her own sutures and the sutures of the director next door, she really didn't want to believe that among the five people, she felt that Li Tingxuan Li Gongzi's sutures were the best at the beginning!

This was a major blow to her career as a mentor.

So she taught one-on-one by one, not to mention that the level of sutures has improved by leaps and bounds, but at least there is some disgraceful progress, and Lu Ning announced that she would leave the class.

After the lunch break, continue practicing.

Studying medicine is so boring, repeating the same thing day after day until you reach your own expectations, and then starting another thing and repeating it again.

If you do research in the laboratory, it will be even more boring, and the taste is not what most people can imagine.

Therefore, those who study medicine must endure loneliness.

Of course, the happiness of arsenic and honey is not something that ordinary people can experience.

Li Tingxuan: They are very happy now, it is the joy of exploring the unknown, and they are happy to do it.

Lu Ning and Xibao are back, and they are still sewing.

After class, they are still sewing and sewing.

It's been an hour after class, and they're still sewing and sewing.

Lu Ning is one hundred and twenty satisfied with studious students, but it must also be moderate, and it is okay to combine work and rest!

Too much sleep and food is really not good for the body, what is the most important thing for a doctor besides medical skills?

It's a healthy body!

Only when your health is better can you have a chance to save more people!

Otherwise, people can't stand up, what's the use of medical skills that climax again?

But she said it a few times, no one listened to her, she was still sewing and sewing there, Lu Ning didn't care about them, and took Xibao out to eat, for the sake of them working so hard, she would consider packing them a dinner and coming back.

But as soon as he took Xibao's little fat hand and went out to the door, he ran into Chunxiao who happened to get off the ox cart.

"Aunt Xiao!!" Hee-Po kept waving his little hands.

"Little boy!" Chunxiao lifted the shoulder bag he was carrying, changed the bamboo basket in his hand to one hand, waved to Xibao, and trotted over, but soon stopped not far away, looked at Lu Ning, and the smile on his face also retracted a lot.

"Didn't you say you'd be back in a few days?" Hee-po asked as he tilted his head while laughing.

"Because tomorrow is the little boy's birthday, the slave maid naturally wants to come back to make longevity noodles for the little boy," Chunxiao stood aside, his eyes full of Xibao.

She was really confused, and went back to the village in a fit of anger, if it weren't for Grandma Liu's mention that she would go to the county tomorrow to celebrate Xibao's birthday, she would have almost forgotten, thinking of this, she glanced at Lu Ning again.

Lu Ning didn't give her the tail of her eyes, and took Xibao's hand and walked out: "Let's go, let's go to Keyun Tower for dinner!" ”

In fact, she didn't take Chunxiao's running away from home to heart at all, her little boy who had worked hard was still here, where could she leave?

"Are you still going?" Xibao blinked his eyes: "I have already been there yesterday, will it be too extravagant to go today, with this money, we can ......."

Lu Ning: "......"

She covered Hee-bo's mouth, she didn't want to hear anything more from him about giving money and helping others.

Who's loser kid!

Xibao's big eyes blinked, pulling Lu Ning's hand down.

Knowing that Daddy didn't like him to spend money on others, he didn't continue to talk about it, but looked at Chunxiao and said to Lu Ning: "Daddy, let's let Aunt Xiao cook, I haven't eaten Aunt Xiao's cooking for a long time, and besides, there is a lot of pork at home, and if you don't eat it, it will be bad!" ”

How can Chunxiao not agree? Lian Lian Ying is that it is her honor that the little boy likes the food she cooks.

But seeing that Lu Ning hadn't spoken, she bit her lip: "Childe...... Slave cook, are you okay to eat at home? ”

Lu Ning is not an aggressive person who does not give up, although it is impossible for her to take the initiative to reconcile with Chunxiao-

First, she was not wrong, second, Chunxiao really broke her heart, and third, she Lu Ning, in her past and present lives, she never bowed her head to anyone!

But since Chunxiao took the initiative to soften, she would also give her a face-

glanced at her and nodded expressionlessly, if it weren't for Chunxiao looking at her all the time, she would hardly have seen the arc of her nod.

Chunxiao: "......"

To say that you are not sad is false.

She took the initiative to reconcile, and she didn't plan to bite the jade pendant, but why did Lu Ning still have this posture?

Are you planning not to talk to her for the rest of your life?

Are you going to drive her away?

No way!

The little boy is still here, she can't go!

Just when he wanted to say something, Xibao cheered: "Eat the meal cooked by Aunt Xiao tonight, can I eat fish fillet porridge?" ”

Chunxiao saw that Xibao was so happy, and she couldn't suppress it in her heart, and the words on her lips became: "Of course you can!" The little boy and Grandpa Liu thought of going together, and he also thought that you wanted to eat fish fillet porridge today, so let the slave and maid bring back the big grass carp, you see-"

The cloth covering the bamboo basket was lifted, revealing two large grass carp weighing five or six pounds, with water weeds through their noses.

Now that the market is closed, you can't buy fish, but fortunately, when Grandpa Liu gave her fish, she didn't shirk it, otherwise she wouldn't know where to find fish just now.
