Da Song a knife

Zhang Sijiu had to praise that this person really hit the mark when asking questions.

She glanced at the other party with approval, and then answered: "Babies and young children, because their bodies are too small, this method is really not applicable. So for them, another method is used. But now there are no props to demonstrate to you, Let me prepare."

Everyone thought they had asked Zhang Sijiu.

I also thought that this preparation would take a long time.

Unexpectedly, Zhang Sijiu asked Yang Yuanding to take off his shirt, and a baby-sized ball of clothes appeared on the spot: "This is the front, and this is the back."

"The first method is to let the baby lie on his lap, fix the head, and raise the head slightly - in fact, it is to fix the throat and not bend it, which will affect the way things come out. Use the palm of the other hand to remove Slap the baby on the back. The force must be controlled properly. Too much force may cause injuries to the baby's bones and internal organs. Too little force may cause things to not come out."

After completing the first method, Zhang Sijiu reversed the picture of the clothes: "The second method is to let the baby lie flat and squeeze the abdomen with the heel of your hand to let the things come out. But the best method is the first method. .”

"You can practice more usually. Many people will choke. Even if it's not for the patients, but just for the people around you, you should practice more."

After the demonstration, Zhang Sijiu returned the clothes to Yang Yuanding, who had a blank look on his face——

At this moment, Yang Yuanding had begun to doubt that if he were to take muscle and joint classes, he would have to be a mannequin.

He thought about the scene for a moment, shuddered silently, and made up his mind that he would never come to class with Zhang Sijiu again.

It makes no sense for a wife to be a teacher and her husband to be a prop...

After Heimlich finished teaching, Zhang Sijiu began to teach CPR again.

This time, everyone obviously studied more seriously - is it still very practical after all?

After being taught ordinary cardiopulmonary resuscitation, a student suddenly asked a question: "Ms. Zhang, what if your stomach is broken, or you need to do this during surgery? Doesn't the pressure squeeze out all the internal organs?"

Zhang Sijiu noticed that this student was the one who asked about baby Heimlich just now.

She looked over with approval again, and then smiled: "Good question. But I'm not going to answer it right away. You can think about it. What would you do if you encountered this situation? I've told you the principle."

Students who draw inferences from one example are good students.

Zhang Sijiu sat down, looking calm and unhurried.

The students were dumbfounded: Are you guessing?

After they looked at each other for a while, someone actually guessed: "If it leaks out, it will leak out. If you turn it back and stuff it back, it will be the same -"

Zhang Sijiu was shocked——

She asked the other party a question: "Do you think the intestines are leaking out and can they be stuffed back? Do you need to push them back and put them back in their original position?"

The other party scratched his head: "No need. It's all in the stomach anyway——"

Zhang Sijiu pressed his forehead and suddenly felt that he might not be suitable to be a teacher.

Finally, she suppressed her anger and looked at the other person with a smile: "Have you ever seen a pig being killed?"

The other person shook his head.Zhang Sijiu made up his mind to buy a pig and bring it over another day to give these students a vivid anatomy lesson.

She took a deep breath and said something serious to the bewildered students: "If you want to be a doctor who can prescribe prescriptions, check the pulse and cure diseases, don't learn bone-setting massage or ulcer medicine. You need to learn either of these." Strength, one needs not only strength, but also the courage to be a butcher.”

A group of students were unconvinced: "We have also seen patients, and we are not studying medicine on the first day -"

There are even people who have treated patients!
Zhang Sijiu nodded and expressed his relief: Very good, no one has backed down!

She continued to talk about the previous topic: "The human intestine is very long when it is straightened, much longer than yours. If it is not arranged properly when it is put back, once the intestines twist or torsion, it will be... Do you know the consequences?"

Everyone shook their heads in unison.

"Intestinal obstruction will occur." Zhang Sijiu sighed: "After intestinal obstruction, the food cannot be removed, and it will be blocked in the knot. That area will become swollen, congested, then necrotic and rotten - and the person will die. It’s too hot.”

"With this kind of high fever, people can easily die. If the fever cannot be cured, the person becomes weaker and weaker. The stomach hurts until the end, the stomach becomes hard, and the pain makes the person roll all over the floor——"

Perforation of intestinal obstruction is complicated by peritonitis.

Even with antibiotics, they are very dangerous.

Some students have already started taking notes with their heads down - they have never heard of these new words.

When Zhang Sijiu saw someone writing it down, he explained it carefully: "The word intestinal obstruction means that after intestinal obstruction, things in the intestine are blocked and cannot flow freely. The cause of intestinal obstruction is that the intestine is twisted. Bending or compression. Once intestinal obstruction occurs, laparotomy should be done as soon as possible. If it is timely, the intestines are not damaged and only need to be arranged properly. If there is already decay and necrosis, only A section of intestine can be cut off and reattached.”

The question-asking person couldn't help but ask: "Can that man still live?"

Zhang Sijiu smiled: "Have you heard of Gu Qingzhou? He performed a very successful intestinal anastomosis back then. Isn't the patient still alive and well now?"

Of course everyone has heard of Gu Qingzhou.

I was thoughtful for a moment.

"Of course, at this stage, it is easy for the operation to fail. If the intestinal anastomosis is not done well, there may be leakage of intestinal contents, or necrosis may occur directly at the anastomosis site, and the operation must be done again, but the vitality of the human body is It’s limited. No matter how good your physical condition is, you can’t withstand repeated surgeries. After all, this is a human being, not a dead thing.”

Zhang Sijiu looked at the students: "So remember, once you start operating one day, you must be careful not to artificially require a second operation. In that case, your patient's chance of survival will become lower and lower. .”

The students were nodding almost involuntarily.

At this time, the time was almost up. Zhang Sijiu packed up his things and said, "Get ready for get out of class to end. By the way, I will assign homework. Now I will choose a monitor to be my deputy. Which one of you is willing to come?"

None of the students took the initiative to apply.

This was expected by Zhang Sijiu. She was not annoyed at all. Instead, she smiled and said, "It's okay. I'll just order one. It's just you. You ask the most questions. What's your name?"

That man was stunned, how pitiful he was. He had so many questions because he was unconvinced and wanted to make things difficult for Zhang Sijiu!
But now that Zhang Sijiu was looking at him, he could only say in frustration: "Shen Tie."

"You go back and write a first aid summary each. Before the next class, Shen Tie, you put it away and give it to me." Zhang Sijiu was not polite at all, assigned the homework and left.

See you tomorrow~
