Two days later.

Ten o'clock in the morning.

College of Liberal Arts Medicine.

At this moment, Zhao Heng was sitting in the classroom, and the person who was lecturing on the stage was Professor Huang Guangyu.

Sitting next to Zhao Heng was Shu Xin, a soft and cute schoolgirl, who glanced at Zhao Heng from time to time, and her mind was not listening to the class at all.

In this class, the old professor is still talking about clinical anesthesia.

Although Zhao Heng has already mastered some knowledge, but listening to the old professor speak again at this moment, Zhao Heng still has a refreshing feeling.

This knowledge is knowledge, understanding is understanding, medicine is a highly applied discipline, not just reading a book.

And Professor Huang Guangyu has also been engaged in clinical practice for many years, and now he will only change to teaching because he is old and his energy and physical strength cannot keep up.

After a while, when it was time for class to end, Zhao Heng stood up and walked to the podium.

"Xiao Zhao, you're here to listen to class again."

The old professor was very happy to see Zhao Heng, after all, at his age, fame and fortune were already clouds for him.

For the old professor, the happiest thing is that there are successors and the career has been inherited.

"Well, I'll rest today, and I'll come over."

Zhao Heng nodded, the old professor was very kind and kind, very similar to Zhao Heng's deceased grandfather.

Therefore, when facing the old professor, Zhao Heng always inadvertently thinks of his grandfather.

"What's wrong this time?"

The old professor said with a smile.

"That's right, the other day, I had an accident under anesthesia."

Zhao Heng talked eloquently, and told the old professor in detail about the sudden cardiac arrest of the patient during the operation a few days ago.

The reason why he said this thing is also to hear whether there can be any new discoveries from the perspective of the old professor, and it can be regarded as accumulating some experience from different perspectives, to see if he can find this hidden danger in the future and before the operation, so as to avoid the occurrence of such a serious accident.

This can be regarded as summing up experience and taking precautions.

"Right atrium air embolism? This is indeed extremely rare. ”

Hearing Zhao Heng's story, the old professor nodded thoughtfully.

"Xiao Zhao, in that case, you can think of doing TEE, and you can also carry out emergency superior vena cava catheterization, which is very good."

The old professor is knowledgeable, he has taught so many students, and in the kind of critical situation that Zhao Heng is facing, there are not many people who can react quickly and correctly.

"Professor, this accident happened too suddenly. From the patient's entry into the operating room, to anesthesia and surgery, the patient's heart rate and blood pressure were not found to be any problems. What could be the cause of such an accident? ”

Zhao Heng asked with some confusion.

What he has now is only the experience of only one class that has fallen from the old professor, so he really can't think of the cause of this possible right atrium air embolism for a moment.

"In general, the common causes of air embolism are thoracic injuries and iatrogenic injuries to the large and medium veins, especially thoracic injuries, which may cause air embolism after allowing gas from the bronchopulmonary to enter the pulmonary veins. In this case, as you said, the only possibility is that the patient has a very small chest injury before the operation, and during the intraoperative anesthesia resting state, the air enters the pulmonary veins and causes embolism. ”

"It's extremely rare, and it's just a coincidence that you come across this one."

The old professor thought for a moment and said slowly.

"Chest injury? If it is a chest injury, the patient should have symptoms before the operation, right? ”

Zhao Heng was still a little puzzled.

"The human body is an extremely delicate system, and any small and unnoticed damage can accumulate and cause serious consequences. When you have more clinical experience, you will be able to understand this. ”

The old professor said very kindly.

For this kind of diligent and talented student, he likes it from the bottom of his heart.

"Well, thank you, Professor."

Zhao Heng nodded, he somewhat understood, what the old professor meant was that the human body was very delicate, and some small injuries might be fine in normal times, but under anesthesia and surgery, the damage could be magnified and cause serious consequences.

is worthy of a professor, this kind of high-level view, ordinary doctors, can't say it at all.

"It's good that you can have this kind of idea and habit of summing up experience, we doctors are not gods, we will make mistakes, so at any time, we must not be careless, we must be cautious."

The old professor was very satisfied with Zhao Heng's attitude, and if he wanted to become an excellent doctor, he must have this attitude.

"By the way, classmate Xiao Zhao, I remember what Ling said last time, you are in the East Hospital, right?"

After a pause, the old professor seemed to remember something and asked Zhao Heng.

"Yes."

Zhao Heng nodded.

"Well, the Oriental Hospital is about to build a center for anesthesia and perioperative medicine, which is a national key project. Xiao Zhao, what is your identity now? ”

The old professor nodded and asked again.

"I've been doing instrument matching in the operating room, and now I'm doing anesthesia with Mr. Gao."

Zhao Heng said very calmly, there is nothing bad to say.

"What?! At your level, why did you only do equipment matching before, but now the East Hospital has really changed. ”

When the old professor heard Zhao Heng's words, he was very dissatisfied.

Zhao Heng didn't speak, at this time, it's not too good to say anything.

"Xiao Zhao, during this time, you are concentrating on preparing for the exam. When you pass the exam, I will recommend it to you. ”

Seeing that Zhao Heng was silent, the old professor naturally knew what was going on, and said very kindly.

In his opinion, an excellent young man like Zhao Heng is simply overkill and ruined by what equipment he does.

Of course, this is also because the old professor is not very satisfied with some of the current hospital's methods and regulations.

At the very least, meritocracy did not do this.

"Professor, won't it be too much trouble for you to get old?"

Zhao Heng was grateful in his heart, but such an old man, if he really wanted to be busy for him, he still couldn't help it.

"What's the trouble here, it's just a trifle."

The old professor said nonchalantly.

Indeed, the old professor is a member of the ministry's committee on anesthesia and perioperative preparation, and he still has a considerable voice, after all, this emerging discipline, the old professor is the originator.

It can be said that even the directors of the anesthesia and perioperative medicine centers of major hospitals, the old professors have the right to recommend and even decide, let alone recommend a young doctor.

After communicating with the old professor again, Zhao Heng returned to his seat, and the old professor, who had already finished class, walked out of the classroom.
