Chapter 55 Discussion
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!"
The shouting worked, everyone stopped talking and returned 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 there will be prizes 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 valuable enough, although it is not as good as not writing medical records for a month.
After Song Zimo finished speaking, he sat down 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 the aura is the inner energy of strength that is released outward.
With several directors away, everyone is much more relaxed and speaks boldly.
Director Tian is young and 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 will secretly ask him for help and intercede.
Dr. Jin was the first to stand up: "Dr. Yang, I want 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?"< br>
"Yes, you are so confident in the steel cable? If it breaks and falls apart, the patient will have to go to the palace for the second time, and the family will go berserk." A doctor said in a low voice.
Yang Ping said:
"There are data on the tensile stress, compressive stress, stiffness, strength, elastic modulus, etc. that human bone tissue can withstand. The data are 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."
"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 admired 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 can help him up and walk without bearing weight. Continue after the operation Lying down loses the advantages of surgery and takes advantage of all the disadvantages of surgery and conservative treatment. A horse can't outrun a horse, and it can't outrun a Mercedes. As for the lawsuit, I haven't done any relevant data comparison. There are many lawsuits, but it’s still late.”
"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 way to avoid lawsuits by going to bed late.
"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 spinal surgery, and his words are high-end and classy. As soon as you open your mouth, others will know that your 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.
"How do you pull out the bone inserted into the muscle? It seems to be 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 with minimally invasive means. First of all, you have to understand which muscle this bone is inserted into and whether there are any important nerves and blood vessels around it. Secondly, you have to understand the depth in the muscle and the bone. Whether the block forms an underhook and whether it can slide out smoothly, and finally, it is necessary to understand whether there are muscles attached to the bone block, and if so, what muscles are attached to it, and to understand the different positions and movements of each group of muscles. 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 the bone block out, and the iliopsoas muscle relaxes. Use a peeler to pry it off. Come out.”
It turns out that extracting a bone requires such advanced anatomy knowledge.
"This surgery is a bit brain-intensive." A graduate student sighed.
Everyone followed the sound and looked over. This guy looked old-fashioned, bald, and had a lot of gray hair.
Judging from his hairstyle, he is obviously at the level of deputy chief physician, but his real identity is a graduate student.
"Do you have any questions?" Song Zimo asked everyone.
Everything is figured 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 K-wires and steel wires. The model has self-stabilizing ability, and I simulate the flexion and extension movements of the elbow joint. During the movement, the model will have a certain degree of self-tightening ability. What we usually do is a loose structure, but yours is a complete dynamically stable structure.”
Dr. Jin thought of the child who had removed the screws 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 disperse 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 a patient 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 the drug was used to speed up renal excretion. The antibiotics were dosed at regular intervals and could not form a superimposed maintenance effect. According to the consultation opinion, the drug for promoting renal excretion was stopped. I retested the drug susceptibility and chose the sensitive drug. You said it worked, and the infection was slowly controlled 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 were chatting while eating.
Professor Zhang appeared at the door, followed by the nurse. Tian Yuan, Yang Ping and Song Zimo got up together.
Originally, Professor Zhang planned to say a few words to everyone 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. It is simply superfluous to go on stage by themselves, so they just listen at the door for a while.
"If you accumulate some more cases and conduct 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 calmer. The system has not released any tasks and is very quiet.
Yang Ping calculated the points and found that he was still 10,000 points away from purchasing the 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 start to improve.
Pelvic fracture surgery must be performed without delay.
Thanks to the dream-chasing mountain god for the reward. Thank you all for your recommendations and collections. Again, I am asking for recommendation votes and collections. During the current trial period, if the results are good, there will be recommendations in the future. Thank you all.
