I can see health

Chapter 283 The Wool

Lu Chen stood on the podium of the demonstration classroom, looking around at the trainees below.

Everyone looked at the question on the blackboard and remained silent for a long time, but still no one could answer the question.

This question involves the difference in body angle.

Lu Chen has experienced the National Medical Skills Competition, so he is naturally familiar with these operations, and he also has a deeper understanding of such skills.

But these students are different. Everyone is confused about many things when they first enter the clinic.

If you can do hepatic jugular reflux, it is already good.

"There is still some time in the future, everyone can read the book, or go to the clinic to practice it." Lu Chen smiled, "I will ask you this question again when we get off work."

Lu Chen made a fool of himself.

He asked all trainees to move about in the department on their own, to inquire about patients' medical history, and to check medical records in the office.

……

The team leader of the interns first came to the ward, tried to do a physical examination on the patient, and did a hepatic jugular reflux sign.

And there were a few other trainees who took out their mobile phones and began to Baidu the answers to Lu Chen's questions on the Internet.

However, after searching for a long time, no one has found the answer to this question.

In the ward, even though the team leader had done the hepatic jugular reflux, he still couldn't answer this question.

"Why is the patient in a semi-recumbent position of 30-40° when doing the hepatic jugular reflux sign? Can't it be in a supine position of 60° or other angles?"

With this question in mind, the team leader approached Cheng Peng.

Of course they asked in a low voice, so as not to be heard by Lu Chen.

"Ah? What's the problem?" Cheng Peng's fat face frowned, "The patient is in a semi-recumbent position of 30-40°? It can't be in a supine position of 60° or other angles? Is there any difference?"

Cheng Peng had never heard of such a weird problem.

The group leader was also quite surprised, even the fellow graduate students didn't know the answer to this question?
"Do you want to ask other teachers again?"

The team leader found Yin Xinhua again with questions.

Yin Xinhua just finished his work.

Seeing a trainee come to ask her a question, she smiled and said she would be happy to answer it.

However, when she heard this question, the smile on her face froze.

Seeing Yin Xinhua's expression, the team leader knew that she might not know either.

"Ah...is this question so difficult?"

……

Finally it was almost time to get off work.

A group of trainees stood beside Lu Chen, waiting for him to announce the final answer.

"You haven't found the final answer yet?" Lu Chen smiled.

The group leader stood up in front of Lu Chen, and quickly shook his head: "I searched all the information, but I still can't find it."

At this time, Cheng Peng also quietly moved his head over.

He is also very curious about this question.

"As for this question, I'll draw a picture, so you may understand it better." Lu Chen took out a blank A4 paper, "The central venous pressure of a normal person is 5-12 cm of water column."

"When supine, the jugular vein is parallel to the right atrium, and the filling of the jugular vein itself will occur, but the filling level is limited to the lower 2/3 of the distance from the upper edge of the clavicle to the mandibular angle."

"In the semi-recumbent position, the vertical distance between the jugular vein, the upper and lower cavities, and the junction of the right atrium is about 15-20 water columns. If the right heart is insufficient, systemic circulation congestion will occur, resulting in increased central venous pressure. If it is greater than 20 cm water column, there will be Distended jugular veins (the jugular veins fill more than 2/3 of the distance from the superior clavicle to the angle of the mandible."

"In the 60° supine position, the vertical distance between the jugular vein and the junction of the upper and lower cavities and the right atrium may be greater than 20 cm of water column. At this time, it is not easy to distinguish cardiac insufficiency."

So this is ah!

If Lu Chen's words were just dictated, everyone might still not be able to understand them.

But Lu Chen still drew the patient's position on the paper.

Clear at a glance!
Most of the trainees, all understand the principle.

This feeling of sudden enlightenment made everyone deeply impressed by the jugular reflux sign.

"Damn it, it turned out to be like this!" Fatty Cheng exclaimed, "You really deserve to be Lu Chen!"

At this time, Lu Chen also received a burst of system prompts.

"Congratulations, the thank you from Cheng Peng is worth +1!"

"Congratulations, the thank you from Ye Qian is worth +1!"

"Congratulations, I received +1 from Su Cai!"

"..."

Lu Chen looked happy, and received more than ten thank you points.

This time with trainees, it can be regarded as no leucorrhea!
……

During the working hours today, as long as Lu Chen finished his work, he would try to help the juniors and sisters in the department to solve the problems.

While constantly gaining gratitude, Lu Chen also gained a good reputation in the eyes of all the interns.

Back in the dormitory at night, on the system panel, the total thank you value reached 126!

When Lu Chen saw the value of gratitude clearly, he was also a little surprised.

This speed is too fast!

However, Lu Chen also knew that the work of taking interns like today can only happen once or twice.

In addition, the teaching of mentors and younger sisters in the department should be done in moderation.

If there is too much wool, they may suspect Lu Chen's attempt.

Especially those junior sisters, if Lu Chen is too enthusiastic, he might misunderstand others.

……

After eating in the cafeteria, Lu Chen thought of Wang Zihao who was hospitalized in general surgery.

He bought some fruit in the supermarket inside the hospital, and then went directly to the general surgery ward.

It was around seven o'clock in the evening.

The entire general surgery ward was relatively quiet.

Lu Chen carried the fruit and came to the No. 12 hospital bed where Wang Zihao was.

Pushing open the door of the ward, he was half leaning on the bed, holding a laptop in his hand.

But his sister Wang Ruoxi was not in the ward.

"Lu Chen, why are you here?" Wang Zihao felt someone coming in, looked up and saw it was Lu Chen, his face was happy.

"You're already in the hospital, of course I have to come here." Lu Chenxiao just put the fruit basket on the table, "Do you feel better now?"

Wang Zihao nodded with a smile: "It's much better, surgery tomorrow morning. Just now Lao Gu also came."

Sitting by the bed, Lu Chen saw that Wang Zihao was still checking documents on the computer.

"Reading a paper?" Lu Chen said.

"Yes." Wang Zihao nodded, "About my own subject."

In his opinion, Lu Chen in the same dormitory is so powerful, and he must try his best to keep up with Lu Chen's pace.

It was only then that Lu Chen remembered that he had promised Wang Zihao to help him check the data.

"Zihao, I have to prepare for the electrocardiogram competition in the next few days, so it may take some time before I can check the data for you."

"It's not urgent." Wang Zihao said with a smile, "You can help me if you have time."

Lu Chen chatted with Wang Zihao for a while.

Wang Zihao suddenly said: "By the way, Lu Chen, did you know my sister before?"

Lu Chen was slightly taken aback, "I didn't know each other before, I just saw it for the first time yesterday, what's the matter?"

Wang Zihao was a little strange.

"After my sister came back from the dormitory this morning, she has been asking about you."

"Ask me?" Lu Chen didn't know why.

"Yeah, I thought she knew you before." Wang Zihao said.

Lu Chen thought of Wang Ruoxi this morning, there must have been no conflict between the two.

Maybe just plain curiosity?
After sitting in the ward for more than ten minutes, Lu Chen returned to the dormitory.

Although he gained a lot of gratitude points today, there is still a certain gap from the 300 mark!
