Let’s eat some fruit cakes, drink some drinks, and take a short rest.
Song Zimo clapped his hands on the podium, and Zhang Lin shouted loudly: "Brothers, Jingyin! Jingyin!"
Shouting works, everyone stops talking and returns to their original positions.
In the past, there would have been few people like Zhang Lin on this occasion, but it is different now. His worth has risen along with Yang Ping and Song Zimo.
"Let's start the discussion?" Song Zimo asked Director Tian softly, mainly to show respect.
Director Tian nodded, and Song Zimo said: "Now is the time for discussion. Everyone can ask questions, and Dr. Yang will answer them. You are welcome, just ask them casually, and you will be rewarded for asking."
"What's the prize?" someone shouted loudly.
"I won't check your existing medical records for a month." Song Zimo said.
This prize is worthy 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.
Strength is here, and aura is the inner energy of strength that is released outward.
Without the absence of several directors, everyone should be much more relaxed and speak boldly.
Director Tian is young, so no one feels any pressure on him.
These young people usually like to ask Director Tian for help when they have any problems. If they make any mistakes, they secretly come to him for help and intercede.
Dr. Jin was the first to stand up: "Dr. Yang, I would like to ask, your stress diversion is indeed very sophisticated, but there is a question, how do you ensure that the bones bear the stress without breaking, and the steel cables continue to bear the stress?"<
/p>
"Yeah, are you so confident in the steel cable? If it breaks and falls apart, the patient will have to go to the hospital for the second time, and the family will go berserk." A doctor said in a low voice.
Yang Ping said:
"There is data on the tensile stress, compressive stress, stiffness, strength, elastic modulus, etc. that human bone tissue can withstand. The data is different for different ages and different parts. There is also data on the fatigue resistance of steel cables.
Yes, there is also data on the number of steps taken by the human body every day, and there is also data on the patient's weight. By combining these data and calculating, you can know how long the steel cable can withstand. The steel cable only needs to hold on until the fracture heals." p>
"I understand, we medical students have to worship Hippocrates, and now we have to worship Newton and Gauss." Dr. King joked.
A graduate student raised his hand and said: "If you go to bed so early, if the fracture is displaced, the patient will file a lawsuit with you; if you go to bed later, even if the recovery is not good and bed rest complications occur, it is better than going to court."
Yang Ping appreciated the young man's frankness and said: "With a hip fracture, there is no doubt that you will go to the ground early. Even if you can't bear full weight, you can bear partial weight; if you can't even bear partial weight, you won't be helped to walk. Continue after the operation.
Lying down loses the advantages of surgery and takes in all the disadvantages of surgery and conservative treatment. A horse-drawn gallop cannot outrun a horse, nor can it outrun a Mercedes-Benz. As for the lawsuit, I have not done any relevant data comparison.
If there are too many lawsuits, it’s better to go to court later.”
"Confidence relies on experience and data, not blindness." Yang Ping added.
The graduate student was very satisfied with the answer. Indeed, this was just what he took for granted. There is no saying that going to bed late can avoid lawsuits.
"According to a multi-center retrospective study, there is no significant difference in the average life expectancy between people who fly and those who do not fly!"
A certain cool guy in the corner said something calmly, with candy in his mouth and couldn't pronounce the words clearly.
It turns out that he is a doctor of spine surgery, and his words are high-end and classy. As soon as he opens his mouth, others will know that his academic qualifications must start with a master's degree.
"The sample has survivor bias." A voice remembered from another corner.
Everyone looked around and saw Xu Stuttering from the emergency department again.
"Teacher Yang!" a graduate student asked shyly.
"It's the bone inserted into the muscle. How do you pull it out? It seems very easy. In my impression, when I encountered this kind of bone several times, I gave up because it didn't matter. If it needed to be anatomically reduced, it could only be cut open.
”
The focus was on stress shunting. I forgot to talk about it until Song Zimo remembered it.
"Just call me Dr. Yang or Senior Brother Yang. It is difficult to reduce this bone block through minimally invasive procedures. First of all, you need to understand which muscle this bone block is inserted into and whether there are any important nerves and blood vessels around it. Secondly, you need to understand the depth in the muscle and the bone."
Whether the block forms an underhook and whether it can slide out smoothly. Finally, we need to understand whether the bone block has muscles attached to it, and if so, what muscles are attached to it. We also need to understand the different postures and action states of each group of muscles. This bone
The bone block is inserted into the pectineus muscle, and the bone block is attached to the iliopsoas muscle. During the abduction process of this bone block, the pectineus muscle is highly tense, squeezing and spitting out the bone block, and the iliopsoas muscle relaxes. With a little pry with a peeler, it will
Come out."
It turns out that extracting a bone requires such advanced anatomy knowledge.
"This surgery is a bit brain-intensive." A trainee lamented.
Everyone followed the sound and looked over. This guy looked old, bald, and had a lot of gray hair.
Judging from his hairstyle, he is obviously at the level of deputy chief physician, but his true identity is that of a graduate student.
"Do you have any questions?" Song Zimo asked everyone.
I've figured it all out and there seems to be no problem.
Seeing that everyone was fine, Director Tian said, "Dr. Yang, the reduction and fixation you did last time when you had a comminuted lower end fracture of the humerus was amazing! I copied your method again and built a model using Kirschner wires.
The model has self-stabilizing ability, and I simulated the flexion and extension movements of the elbow joint. During the movement, the model will have a certain self-tightening ability. What we usually make are loose structures, but yours is a complete dynamically stable structure." p>
Dr. Jin thought of the child who had the screws removed and said: "The two screws have been removed. If the symptoms are really relieved, I will treat you to dinner and have a good chat."
"No problem, let's break up the meeting." Song Zimo announced.
Everyone saw that there were refreshments, so they all rushed to eat more and chat with each other.
"I have to go back and check out the anatomy, physiology, and pathology. Really, last time there was a patient who had an infection and couldn't control it with antibiotics. They all used the medicine according to the drug sensitivity test. It didn't work to change the antibiotics or increase the dosage.
Later, I asked the nephrology department for consultation. They said that they were taking drugs that speed up renal excretion. The antibiotics were dosed at regular intervals, which could not form a superimposed maintenance effect. The blood concentration of the drug was always unable to reach the therapeutic level. According to the consultation opinion, the drugs that promote renal excretion were stopped.
I re-tested the drug susceptibility and chose the sensitive drug. You said it worked really well, and the infection was slowly under control in a few days."
"Yes, surgery can be done this way. I wouldn't know it if I didn't hear it today. It's an eye-opener."
Two graduate students and several graduate students chatted while eating.
Professor Zhang appeared at the door, followed by the nurse, Tian Yuan, Yang Ping and Song Zimo got up together.
Professor Zhang originally planned to tell everyone a few words before the meeting ended, but when he saw the simple and clear animation demonstration on the screen, he changed his mind.
Young people have their own language and methods, and it is superfluous to go on stage by themselves, so they just listen at the door for a while.
"If you accumulate some more cases and do mechanical analysis on these internal fixation structures, you can publish a book in the future - Orthopedic Internal Fixation Structures" to specifically discuss the design of these stable structures.
Professor Zhang talked to Tian Yuan, Yang Ping and others, and then returned to the ward with a cane.
Saturday was spent like this.
Su Yixuan sent a WeChat message to tell Yang Ping that there were two pairs of slippers in the shoe cabinet in his operating room, and his slippers were cracked.
Sunday was also relatively calm. The system did not release any tasks and was very quiet.
Yang Ping calculated his points and found that he was still 10,000 points away from purchasing pelvic fracture training. The gap was a bit big.
Only after completing the pelvic fracture training can you feel a little relieved.
Otherwise, if you suddenly suffer a pelvic fracture, you may not be able to cope with it.
Although the basic skills of surgery have also reached the master level, the number of surgeries must be accumulated before you can master them.
Pelvic fracture surgery must be performed without delay.
