Chapter 400 Professor Zhu(1/2)
Four emergency rooms were treated so quickly. This is really inappropriate.
Zhou Ziyu asked: "Are you there later? Are you going to have dinner together?"
Lu Chengcheng said: "I don't have one here anymore. If there is one more, Brother Ziyu, you will have to take my seat. But there is a machine in the Department of Orthopedics that replants severed fingers, and I want to take a look."
Lu Cheng joked and declined.
The Department of Orthopedics currently specializes in hand surgery and microsurgery. Although Lu Cheng also knows about replantation of severed fingers, that was all when he was in Changshi. Now that he is the chief resident, of course he needs to gain more knowledge.
Take a look at the differences between the professors in the Department of Orthopedics and your own philosophies.
It's already this late anyway, so I probably won't be able to sleep for long after I go back.
Zhou Ziyu nodded: "Then will you go back directly later or go to the operating room for a visit?"
Lu Cheng's surgery was finished. It was already two o'clock in the morning. Lu Cheng had also completed three emergency surgeries. At this point, even if he was hospitalized and went home to take a nap, no one would say anything.
Lu Cheng replied: "Let's go to the operating room and see. Replantation of severed fingers is still rare."
"Then I'll leave first. I wish you will step down soon."
"Good night dreams." Zhou Ziyu didn't want to imitate Lu Cheng, a pervert. Even though he was so good, he still had to study so hard and be able to complete his postgraduate and doctoral studies so quickly, and when he was admitted to the general hospital, there must be merit.
But being a doctor is a lifelong matter, and if you are gone, nothing will be left.
"Thank you, Brother Ziyu, you have such a good dream." Lu Cheng replied.
Chief residents, as you can tell by their name, are doctors who always live in the hospital. If you want to have a good dream, you must avoid emergency rooms.
Zhou Ziyu chewed betel nut, smoked a cigarette, and went to change clothes. It was probably time to go back to the department to rest...
The operating room was brightly lit, the anesthesiologist was dozing, and the vital signs on the anesthesia machine were very stable.
The difficulty in replanting a severed finger is the technique, which does not pose a great threat to the patient. Moreover, because the severed finger has a tourniquet or a blood-driving tape, there will not be a lot of bleeding during the operation.
On the operating table, several people were concentrating on the operation.
There were three people standing around one hand, and there were only two mirrors, which had been divided up long ago. Not to mention Lu Cheng, not even the operating class had a chance to see it. So they just watched from the audience.
No one noticed his arrival.
Lu Cheng watched as he recalled the surgical procedure for replanting a severed limb.
Now, when Lu Cheng recalls the surgical procedure, he is no longer as step-by-step as before.
Replantation of a severed finger is slightly simpler than replantation of a severed limb due to the size of the operation.
But the operation is not simple.
However, for all traumatic surgeries, the first principle will never change.
Rinse, debridement, rinse again, rinse thoroughly, debridement thoroughly, remove necrotic tissue and foreign matter from severed fingers!
If there is no thorough debridement and thorough removal of foreign matter, no matter how good the suturing and docking are, it will all be fake. The final effect will definitely be poor, and wound necrosis and infection will easily occur.
But it is a pity that this step has been completed long ago, and the process of connecting the bones has been completed. Professor Zhu has already sutured the blood vessels and nerves of the third finger, and is now in the finishing process.
But through those few Kirschner wires at zero point!
Lu Cheng also knew the second step in replanting a severed finger:
The second principle of replantation of severed fingers is to first harden then softly. The bone must be attached first and then the soft tissue. The soft tissue includes blood vessels, nerves and tendons; blood vessels have the highest priority.
Because only after the blood vessels are unblocked can we discuss the big topic of whether nerves can survive and whether tendons can survive.
If the nerves and tendons are necrotic in the end, no matter how good the suturing is, it will be useless.
The broken ends of the fracture are cross-fixed with Kirschner wires to form four semi-open triangles to fix the broken ends of the fracture.
The microscope was brought in and adjusted. With eyes facing the eyepiece, adjustments were started. After adjusting the focal length and interpupillary distance, the field of view was finally clear.
After the bones are connected, it is time to anastomose the blood vessels and nerves.
The stumps of the broken fingers and blood vessels that the professor is currently working on have been sorted and trimmed, and the broken ends of the blood vessels have already become clean and neat.
Moreover, the professor has already sutured more than half of the proper digital artery in a circle, and what he is currently doing is the proper digital artery on the ulnar side of the middle finger.
The proper palmar artery of the finger is divided into the radial and ulnar sides of each finger, commonly known as the inner and outer arteries.
The proper volar digital arteries of the middle finger all originate from the common volar digital artery. Professor Zhu held the fiber suturing needle and tweezers, but Chen Ding also needed to use a microscope to assist and cut the thread at the other end.
The diameter of the proper palmar artery is very small, perhaps only a little over a millimeter, but it requires at least six stitches around such a small blood vessel, which is obviously not an easy task.
Microscopic sutures, which are much thinner than a hair, are constantly inserted and pierced under the microscope in Professor Zhu's hands. This process is not very smooth, but it is not sloppy. Most of them are stitched to the end.
But in the process of tying the knot, it was very slow.
Because such a small blood vessel is very fragile, as long as the force is slightly greater, the blood vessel may be directly broken. In this way, most of the previous suturing operations are definitely possible.
So the professor is very cautious.
This operation has lasted for two hours so far.
The surgical class was so focused that they were a little distracted. The chief resident next to him saw his hands shaking slightly, but he didn't blame him. The surgical class were just students, and they couldn't be expected to have the same energy and abilities as those who had been on the battlefield.
.
With just one glance, he saw Lu Cheng who was watching the operation in the audience, and immediately asked: "Brother Xiao Cheng? Is this halftime? It's hard enough."
The former chief resident of the Department of Orthopedics was named Huang Minzhi, but he has completed the first term of general residency with Lin Hui, and now the chief resident is called Chen Ding, and he was the same term as Lu Cheng.
Chen Ding naturally thought that Lu Cheng came here for a casual look, after all, it was at this point.
"No, I just came over to study after I finished it." Lu Cheng didn't hide it either.
Chen Ding was stunned for two seconds. Even the professor next to him frowned slightly and said: "You have finished all three emergency rooms? Are you the chief resident of the trauma surgery department or the assistant chief?"
When he was preparing for the operation, he heard the nurses in the operating room complain that the trauma center was extremely busy, and there were three or four surgeries lined up for the surgery next door...
His tone was a little unhappy.
As a professor of microsurgery, he does not think that speed of surgery is something to be proud of. On the contrary, the ultimate result of surgery is what he pursues.
Lu Cheng's face was covered by a mask, but he looked young.
"Teacher Zhu, this is Lu Cheng from the trauma center. Teacher Zhou Xuanqing mentioned it before."
Lu Cheng looked quite embarrassed when he heard Chen Ding say the word "Professor Zhu". He had heard Fang Nixin talk about the grievances between Zhu Jun's teacher and his own teacher, Professor Li Dongshan.
If you come in hastily, will it cause displeasure to the other party?
When Lu Cheng looked at Zhu Jun, Zhu Jun also looked at Lu Cheng, and then asked very suddenly: "Do you still have the physical strength? Can you still go on stage?"
"If I can get on stage, I'll change with this little brother."
Professor Zhu naturally saw the hand tremors in the surgery class, but it was an emergency surgery and it was late at night. The other surgery classes were called away by Lu Cheng. No one was looking for him, so he had to make do with it.
Lu Cheng said: "Then I'll wash my hands right away."
When the surgical team heard this, their eyes lit up. Originally, he could not see many things with his naked eyes when replanting a severed limb like this.
He quickly said to Lu Cheng: "Thank you, teacher."
Lu Cheng smiled and said it was okay.
I quickly washed my hands and dressed, and then took my place in the surgical class.
Although Chen Ding and Professor Zhu each occupied most of the operating table's field of view with a mirror, there were not many assistants blocking the view at this moment, so Lu Cheng could still see very clearly how Professor Zhu sutured.
Professor Zhu continued to sew the next stitch, while Chen Ding continued to help him cut and pass the thread, occasionally holding the needle to fix it.
Lu Cheng helped the two of them fix their fingers and position themselves.
Because the proper palmar arteries are on both sides of the fingers, when suturing the radial end, the index finger will block the view and operation.
Moreover, the index finger has just been replanted after being severed, so it is not suitable for forcefully opening it.
However, Lu Cheng still pressed the patient's index finger and thumb slightly with his hand, and his field of vision was suddenly much wider than before. Moreover, he also asked the patrol to open an extra pair of gloves, and then used the gloves to cover the ring.
The first knuckles of the finger and little finger were pulled on the surgical drape.
It can perfectly expose the operating space.
With just such a move, Professor Zhu suddenly felt energetic. The movement of his hand sped up by at least three points. While taking out the needle, he asked: "Where did you learn this from?"
A layman watches the fun, an expert watches the door.
Professor Zhu has been replanting amputated fingers for so many years, but rarely has such a broad field of vision, and the stump of the patient's amputated finger is not written in the textbook, so there is no exposure during the operation.
strict standards,
Lu Cheng said: "Professor Zhu, during the regular training, an old director used it during surgery. I thought it was quite practical, so I wrote it down."
"I thought I might need it in the future, so I happened to use it today."
Chen Ding was afraid that Zhu Jun didn't understand Lu Cheng, so he quickly said: "Dr. Lu Cheng is from the place where live-in escorts come from, and he just came to Appendix 2 not long ago."
Professor Zhu nodded and praised without hesitation: "You know how to pay attention to details, which is very good."
“The ability to apply it flexibly is also very strong.”
"Have you ever done this?" Zhu Jun suddenly said something that surprised Lu Cheng.
Chen Ding's pupils also shrank slightly. Wasn't it rumored that Professor Zhu was not on good terms with Professor Li Dongshan?
