Out of the operating room, it's almost time for dinner.

Li Xiyang returned to the office to sort out some cases, and then went to the cafeteria.

At this time, there were not many people in the cafeteria, and Li Xiyang came to the window with a plate.

"Auntie, what are the dishes today?"

"Ah, Doctor Li, this braised pork has just come out of the pot, let me give you some?"

The cafeteria aunt was very welcoming.

They had only recently settled in Renhe, but a young doctor in the emergency department had been in the newspaper several times, and it had already spread among the people.

On top of that, the young man is also very handsome and very likable.

"Thank you, Auntie."

Li Xiyang handed the dinner plate to the other party.

"No thanks, no thanks, you work too hard as a doctor, you should eat more meat to make up for it!"

As she spoke, the aunt went down with a spoonful, and the braised pork instantly filled most of the plate.

Seeing this, Li Xiyang hurriedly waved his hand, "Auntie, it's a lot!" ”

I can't finish eating so much!

"Why can't you finish eating, Dr. Li, you're too thin, so you need to eat more!"

"I'll give you some other dishes, meat and vegetarian matching, this work is exciting!"

As she spoke, the aunt shoveled a few more vegetarian dishes for Li Xiyang, each of which was super large.

Li Xiyang smiled bitterly, this aunt is too enthusiastic.

In a few moments, a small mountain of plates was piled up.

Li Xiyang took it with a wry smile, thanked him a few more times, and then turned around and found a place to sit down.

Looking at the full plates, Li Li Xiyang smiled bitterly, let's eat as much as you can.

So he lowered his head and picked up the food.

After just a few bites, I saw Zheng Xiaoyu sitting next to him with a plate.

"How's it going, has the ballast been taken out?"

Li Xiyang thought that it must have been Dou Wenhua and her.

"Take it out, it's not as big as this rice!"

At this time, Zheng Xiaoyu noticed Li Xiyang's plate, and his eyes widened suddenly, "What's the situation, why do you have so many dishes?" ”

Li Xiyang glanced at the other party's plate, good guy, less than one-third of his own.

There are also braised pork on the key plates, and Zheng Xiaoyu's amount is pitiful.

looked at Li Xiyang, and then looked at the aunt over there, Zheng Xiaoyu instantly understood, and said angrily, "Hmph, it's really too much!" ”

She asked her aunt to give her more meat just now, but the other party said that she was too thin to eat and waste, so she asked her to eat and fight again.

This is a pure look at people and food.

"No, I'll reason with her!"

Li Xiyang hurriedly stopped and said with a smile, "Okay, you can eat quickly, I still have a lot of here, anyway, I can't finish eating, you just eat it." ”

Hearing Li Xiyang say this, Zheng Xiaoyu smiled and said, "Then since that's the case, I'll barely eat a little." ”

Li Xiyang smiled and shook his head, and continued to grill rice.

……

Time flies, and it's Friday in a blink of an eye.

Fridays in the emergency department are not very quiet, but because there are the most medical staff on duty, it is relatively relaxed.

also took advantage of the rare leisure, Li Xiyang went to the experimental building.

Today is the intern's first lab operation class!

When I entered the operation room, there were already many interns waiting inside.

"Hello Mr. Li!"

"Hello Mr. Li!"

The first time he was called a teacher, Li Xiyang is really a little unaccustomed!

"Hello!"

"Let's get ready, and when everyone is ready, let's start!"

But another ten minutes passed, and the agreed time had passed, but no newcomers came in again.

Li Xiyang counted the number of people, 18 people!

No, there should be 32 students assigned to him.

How did it suddenly fall short of 14.

"What about the others? Do any of you know why those people haven't come yet? ”

Li Xiyang opened his mouth to ask, and immediately noticed that everyone's faces became a little strange.

"What the hell is going on?"

Is it in the department or is it late?

Li Xiyang asked a few more times, but still no one spoke.

"Don't say yes, do you?"

"Okay, you don't need to take this operation class!"

Li Xiyang turned around and was about to step off the podium.

He didn't want to do anything to teach, and since no one believed him, he didn't bother to waste time here.

At this time, a chubby girl raised her hand, "Teacher Li, I know where they are!" ”

"Where?"

The girl pointed to the door, "It's right next door!" ”

Next door?

Li Xiyang was stunned for a moment.

Next door is the No. 2 operation room, which is the class taught by Dong Xiaoyun!

"What are they going to do there?"

"He... They said they wanted to learn from Mr. Dong, no... I want to learn from you. ”

The girl was stumbling and told the story.

Only then did Li Xiyang understand.

Just when everyone thought that Li Xiyang would be furious, they heard the former ask, "What about you, why don't you go?" ”

Some people spoke one after another, "I want to learn from Teacher Li!" ”

"Yes, I want to too!"

Not surprisingly, these are girls.

Although the rest of the boys also echoed, the expressions on their faces were unnatural.

Obviously, if it weren't for the fear of offending Li Xiyang, they must have followed at this moment.

Li Xiyang didn't care about this.

After all, when people go to higher places, they want to learn from better teachers.

In other words, he must also hope that the teacher is the best.

Understandable!

"If anyone else wants to go next door, if they want to go, they can go now!"

Everyone looked at each other, "What do you mean by Mr. Li?" ”

"You won't be angry, will you?"

"It doesn't look like it, I'm still smiling!"

"Is it true?"

"What, do you want to go over?"

"Ahem, I... I didn't..."

Seeing that no one left, Li Xiyang re-stepped onto the podium.

"Okay, since no one is leaving, then I'll assume that you want to learn from me."

"If I find someone leaving without permission next time, I will notify the academic affairs."

Li Xiyang rarely loses his temper, but there are still rules that should be there at work.

He didn't mind giving up his job as a teacher, after all, he was already very busy, and he really didn't have the leisure to do so.

But if someone is willing to learn from him, he will not be stingy.

"Okay, now let's get down to business, but before I start teaching you how to do it, I'd like to put you to the test."

Li Xiyang's eyes swept over everyone's faces one by one, and asked, "Can anyone tell me what is the most important point of debridement and suture?" ”

The chubby girl from before raised her hand, "I, I know!" ”

Li Xiyang nodded, "Okay, you can come!" ”

"It's the choice of suture tension and suture."

Li Xiyang nodded, "These are indeed important, but listen clearly to what I asked is the most important point." ”

"The heaviest either..."

A man with glasses thought for a moment and said, "It should be the doctor's technique and technique." ”

Li Xiyang still shook his head.

What's that?

Everyone, you look at me, I look at you, all with a puzzled face.

Seeing that no one raised his hand again, Li Xiyang said strangely, "Didn't anyone think of disinfection and sterilization?" ”

Sterilization?

Everyone is puzzled, how can this be the most important point of debridement and suturing?

Generally speaking, the debridement work is done by the assistant nurse, and suturing is the most important thing in wound management.

Seeing everyone's doubts, Li Xiyang said, "In any clinical operation, disinfection and sterilization are always the first step, without disinfection and sterilization, even if the surgeon's technique is good, the patient's postoperative wound infection will directly threaten Dao's life!" ”

Everyone nodded, saying that's true, but...

Obviously, the crowd still can't fully accept this statement.

Li Xiyang smiled and continued, "As early as the 18th century, surgery was very common in European countries, but the mortality rate of surgery was unimaginably high.

Historically, the post-operative mortality rate in Paris is 60%, in other words, 6 out of every 10 people in Paris who undergo surgery. ”

I'll go!

Everyone was shocked.

With such a high mortality rate, until now, those main knives have to be pulled and shot one by one!

Li Xiyang nodded, "This problem has lasted for a whole century, the appearance of Semmelweis!" ”

"Semmelweis?"

"The Hungarian obstetrician?" A Ph.D. intern asked, holding his eyes.

Li Xiyang nodded, "That's right!" ”

Semmelwes worked in the Department of Obstetrics and Gynaecology at the Vienna General Hospital, where he was responsible for welcoming a new baby.

At that time, a large proportion of these women would develop puerperal fever after giving birth, and the mortality rate of puerperal fever in the hospital was 18%.

Semmelwes soon discovered the strange thing, that is, the number of maternal and neonatal deaths due to the disease in the second maternity hospital, where birth attendants are trained, is significantly lower than that in the first maternity hospital, which is 2.7 per cent.

Even women who give birth at home are less likely to suffer from puerperal fever than in the first maternity hospital.

At that time, the cause of puerperal fever was unknown, and Semmelweiss proved that the "harmful gases" in the air, maternal fear, constipation, etc., were not related to the onset of the disease.

In addition, he tried to change the delivery position and postpone the lactation period, but found that he could not control the disease.

Until 1847, when a friend of his forensic doctor was doing a pathological autopsy, his finger was accidentally cut and infected, and he died of sepsis.

Post-mortem examination revealed pathological changes that closely resembled those of women who died of puerperal fever.

This incident inspired him, and he found that doctors and interns often went into the ward to examine or deliver mothers without washing their hands after a pathological autopsy.

It is inferred that puerperal fever is caused by the doctor's unclean hands or obstetric instruments that introduce some infectious material into the maternal wound.

For this reason, he ordered medical students to wash their hands with a bleach solution before examining the mother.

Sure enough, the infection rate dropped dramatically a month after the practice was implemented.

The following year, he soaked the surgical instruments with bleach, which reduced the postoperative mortality rate of the patients again.

In 1855 he became professor of obstetrics at the University of Pest, and his method of sterilizing obstetrics was recognized in Hungary.

In 1861, he published "The Etiology, Concept and Prevention of Puerperal Fever", in which he used a large number of statistical data to illustrate and demonstrate his findings and theories.

He sent his writings to prominent obstetricians and medical societies abroad, and his concept finally gained the attention of many.

Since then, the mortality rate of surgical procedures has been greatly reduced.

More and more patients are strikingly prolonging their lives through surgery.

It's just that the times have developed to this day, and disinfection and sterilization have become the first step in surgical operations, so many people ignore his importance.

A group of interns suddenly understood what Li Xiyang meant.

"Okay, I'm saying all that, I really just wanted to ask,"

After a pause, Li Xiyang's gaze swept over everyone one by one, "How many of you washed your hands just now?"
