Let's eat some fruit pastries, drink some drinks, and take a break.

Song Zimo was on the podium, clapping his hands, and Zhang Lin shouted loudly: "Brothers, mute!" Mute! ”

The shouting worked, and everyone stopped talking and returned to their places.

If it was on this occasion in the past, there were few people and birds Zhang Lin, but now it is different, and his value has risen with Yang Ping and Song Zimo.

"Let's start a discussion?" Song Zimo asked Director Tian softly, mainly to show respect.

Director Tian nodded, and Song Zimo said: "It's time for discussion, everyone asks questions, and Dr. Yang will answer, don't be polite, just ask casually, there will be a prize for asking." ”

"What's the prize?" Someone shouted loudly.

"I don't check your medical records for a month." Song Zimo said.

The prize is enough, although it is not as good as not writing medical records for a month.

After Song Zimo finished speaking, he sat next to Yang Ping in the first row: "It's your turn." ”

Yang Ping stepped onto the podium, and everyone applauded, wave after wave.

The strength is here, and the aura is the internal and external release of strength.

In the absence of a few directors, everyone was much more relaxed and spoke boldly.

Director Tian is young, and everyone has no sense of pressure on him.

These young people usually like to ask Director Tian for advice if they have any problems, and if they make any mistakes, they secretly ask him to help intercede.

Dr. Jin was the first to stand up: "Dr. Yang, I would like to ask, your stress diversion is indeed very exquisite, but there is a question, how do you ensure that the bone block does not break under stress, and the steel cable is constantly stressed by it?"

"Yes, you have so much confidence in the steel cable? In case it is broken, it will all fall apart, and the patient will have to enter the palace twice, and the family will run wild. A doctor whispered.

Yang Ping said:

"There are data on the tensile stress, compressive stress, stiffness, strength, elastic modulus, etc., that the human bone tissue can withstand. The data are different for different ages and different parts. There is also data on the fatigue resistance of the steel cable, there is also data on the number of steps of the human body per day, and there is also data on the weight of the patient. ”

"I see, we who study medicine have to worship Hipporates, and now we have to worship Newton and Gauss." Dr. King joked.

A graduate student raised his hand and said, "If you go down to the ground so early, if the fracture is displaced, the patient will come to you for a lawsuit; If you go to the ground late, even if you don't recover well and cause complications in bed, it's better than going to court. ”

Yang Ping admired the young man's honesty and said: "Hip fracture, early to the ground, there is no doubt." Even if you can't do it completely, you can partially load it; I can't even carry some of the weight, so I don't carry the weight and walk up. Continuing to lie down after the operation has taken away the advantages of surgery and the disadvantages of surgery and conservative treatment. Horse-drawn galloping, neither running horses nor galloping. As for the lawsuits, I didn't make a comparison of the relevant data, whether there were more lawsuits in the early and late in the ground. ”

"Self-confidence is based on experience and data, not blindness." Yang Ping added.

The graduate student was very satisfied with the answer, indeed, it was just a matter of taking it for granted, and there was no place where a lawsuit could be avoided by going to the ground late.

"According to a multicenter retrospective study, there was no significant difference in life expectancy between people who flew and those who didn't!"

A certain cow man in the corner calmly threw out a sentence, with sugar in his mouth, and his words were not very clear.

It turned out to be a doctor of spine surgery, which is high-end and high-end. As soon as you open your mouth, others know that your academic qualifications must start with a master's degree.

"Teacher Yang!" One of the trainees asked shyly.

"It's that piece of bone stuck in the muscle, how do you pull it out, it seems to be very easy. In my impressions, I encountered this kind of bone several times, and I gave up if it didn't matter, and those that had to be dissected and reduced could only be incised. ”

The focus was on stress diversion, and I forgot to talk about this, so Song Zimo remembered.

"Just call me Dr. Yang or Senior Brother Yang, it is difficult for this bone to be minimally invasively reduced, first of all, you have to understand, which muscle is inserted into this bone block, and whether there are important nerves and blood vessels around, secondly, you must understand the depth in the muscle, whether the bone block forms a barb, whether it can slide out smoothly, and finally you must understand whether the bone block is attached to the muscle, if so, what muscle is attached, and understand the different positions and action states of each piece and each group of muscles. This bone block is inserted into the pubis muscle, and the iliopsoas muscle is attached to the bone block. During the abduction of this bone block, the pubic muscle is highly tense, squeezing and spitting out the bone block, the iliopsoas muscle is relaxed, and it comes out with a slight pry of peeling ions. ”

It turns out that pulling out a bone block requires such advanced anatomical knowledge.

"It's a bit brain-burning." A regular trainee sighed.

Everyone followed the sound and looked over, this guy looked old-fashioned, he had lost his head, and he had a lot of gray hair.

Looking at the hairstyle, it is obvious that he is already at the level of deputy chief physician, but his real identity is Gui Peisheng.

"Do you have any questions?" Song Zimo asked everyone.

It's all figured out, and there doesn't seem to be any problem.

Director Tian saw that everyone was fine, and said, "Doctor Yang, you had a comminuted lower end fracture of the humerus last time, and that reduction and fixation is amazing!" I re-followed your method and built a model with K-wire wire, which has self-stabilizing ability, and I simulated elbow flexion and extension movements, and during the movement, the model will have a certain self-tightening ability. What we usually do is a loose structure, but yours is a complete dynamic stable structure. ”

Dr. King thought of the child who had taken the screws and said, "The two screws have been removed, and if the symptoms are relieved, I will treat you to dinner and have a good chat." ”

"There's no problem, let's just break up." Song Zimo announced.

Everyone saw that there were still refreshments, so they all rushed to eat more, and chatted about it by the way.

"I'll have to go back and look at the anatomy, physiology, pathology. Really, last time a patient was infected, and he couldn't control it with antibiotics, so he used it according to the drug susceptibility test, and it was not possible to change the antibiotic, and it was not possible to increase the dose. Later, I consulted the nephrology department, saying that drugs to speed up renal excretion were used, and antibiotics could not be superimposed to maintain the benefits according to the regular doses, and the blood concentration of the treatment was always not reached. According to the consultation opinion, stop the kidney-excretion drugs, re-test the sensitive drugs and select the sensitive drugs. ”

"Yes, the operation can be done like this, if you don't listen to it today, it's an eye-opener."

Two graduate students, a few trainees, chatting while eating.

Professor Zhang appeared at the door, the nurse followed, and Tian Yuan, Yang Ping, and Song Zimo got up together.

Originally, Professor Zhang planned to give a few words to everyone before the meeting, but when he saw the animation on the screen, which was simple and clear, he changed his mind.

Young people have their own language and way, and it is purely superfluous to go on stage on their own, so they only listen for a while at the door.

"You can accumulate some more cases, do a mechanical analysis of these internal fixation structures, and then you can publish a book - Orthopedic Internal Fixation Structures", which is dedicated to the design of these stable structures.

Professor Zhang said to Tian Yuan Yang Ping, and after speaking, he went back to the ward with a cane.

That's how Saturday went.

Su Yixuan sent a WeChat message and told Yang Ping that in the shoe cabinet in his operating room, two pairs of slippers were placed, and his slippers were cracked.

Sunday was also calmer. The system did not issue any tasks, and it was very quiet.

Yang Ping calculated the points, and there were still 10,000 points away from purchasing pelvic fracture training, and the gap was a bit big.

Only after completing the pelvic fracture training can you be a little relieved.

Otherwise, if you suddenly fracture your pelvis, you may not be able to cope with it.

Although the basic skills of surgery have also entered the master level, the number of surgeries must be accumulated in order to be improved.

Pelvic fracture surgery, which must be taken down, is urgent.
