After the knee replacement surgery, Professor Min left work.

The arthroscopic surgery in the back can be handed over to Zhu Queguang and Lin You.

Of course, Professor Min's off-duty work is just that people are not in the hospital.

Although he has only been in the hospital for half a month, Lu Cheng also knows that Professor Min has always had the habit of looking for literature after work, and it is estimated that he is now going to study the 1st bed in the prison, whether to have surgery or not, and what are the indications for surgery.

As a junior doctor, Lu Cheng has such an advantage that as long as Professor Min studies this case, he can take the initiative to ask, which can reduce many detours for him.

After asking the answer, combined with Professor Min's statement at that time, Lu Cheng will be able to grasp the indications for surgery in patients with pulmonary infarction in the future.

These cases, which seem to outsiders to be almost absolute contraindications to surgery, can also be managed.

These are all cumulative.

Accumulation is the only way out for medicine.

Lu Cheng is not in a hurry, he will definitely not touch this case first, the accumulation is not enough.

Just by checking the literature, it is impossible to determine who is telling the truth and who is not telling the truth, and if you don't have enough clinical experience, you want to accurately grasp what others say, which is unlikely, but will make you fall into it and can't get out.

This has a big impact on my learning progress.

Hikaru Suzaku completed the two rotator cuff stitching.

It took more than three hours.

One of the hours is spent on transferring and inserting the patient and administering anesthesia. This is the time that has to be spent between surgeries.

The two rotator cuffs were stitched, and Lu Cheng seemed to understand it.

The main thing is that I don't know much about the shoulder joint.

Surgery is not just a way of surgery, but also a systematic understanding of anatomy, pathogenesis, approach, and so on.

The next meniscus is Lu mature, and he believes that continuing to observe will be more beneficial to his own growth.

Meniscus surgery, Zhu Queguang will not go on stage, and it will all be handed over to Lin You to do.

The patient was Lu Cheng's, so everyone else was arranged by Lin You.

Including Shi Ding and Chen Hui.

Shi Ding and Chen Hui were also happy, anyway, they were about to vomit with this kind of operation.

Since Lin You has the heart to cultivate Lu Cheng, a seedling that they are all optimistic about, they have no opinion, if Lu Cheng can grow up quickly, the work of their working group will only become easier and easier.

Wash your hands, disinfect, spread towels, put on clothes, and then lay the outer layer of knee joint waterproof sheet, Lu Cheng did it in one go.

Before disinfection, Lu Chengcheng took the initiative to find and mark the knee eye of the knee joint.

For Lin You, the mark of the knee eye is extra and unnecessary, but for Lu Cheng, it is indeed an important way to learn, and he does not need it if he has accumulated enough experience and experience.

Lin You watched Lu Cheng paste the waterproof membrane, and waited for him to come to the stage, and while wearing the waterproof clothing, he said with a smile: "You are quite well prepared." ”

"The tourniquet is hit, you drive in first?"

Lu Cheng glanced at Lin You, it seemed that Lin You was not joking with him.

"Okay. Master. ”

Lu Cheng replied while receiving the arthroscopy sleeve and irrigation tube.

Somewhat in a good mood.

Lin You is really a good master, and he has given him too many opportunities to do it.

From yesterday's tendon suturing to today's surgery, this is a treatment that the senior brothers of the second or third research institute do not have.

Since Lin You is not joking, then let's do it yourself.

After connecting the suction device, Lu Cheng shouted directly to the hand-washing nurse: "Teacher, give me a bent plate and add some kidney protection." ”

Lu Cheng recalled the preparations to be made before the opening of knee arthroscopy, and at the same time confidently put his mind calm.

Kidney protection is another name for epinephrine in joint surgery.

Before knee arthroscopy, it is necessary to fill the knee joint, and if it is filled with normal saline with epinephrine, it can reduce a lot of bleeding.

The nurse didn't know how many surgeries she had performed, so she directly brought up the curved disc with kidney protection, and Lu Cheng used a water dispenser to take out about 30 ml of water, and with a 10ml syringe, after pushing the patella, he was close to the patella and punctured it.

It was very smooth, and Lu Cheng easily felt the sense of breakthrough that the master said about entering the joints on weekdays.

To protect the kidneys, 30 ml pushes it in.

And, the last 5ml, push it into the subcutaneous eye of the knee joint of both knees.

This is the arthroscopy in the position, and with the addition of kidney protection, it can still reduce bleeding and better enter the knife.

Countless details, piled up into a perfect surgery.

"Teacher, sharp knives. Lu Cheng shouted again.

Lu Cheng took the sharp knife in his hand, took the outer knee eye as the approach, pointed the tip of the sharp knife downward, and poked it in according to the mark.

It is about 1cm into it, and it does not need to reach the joint cavity, but only needs to go to the synovial space, and then use straight forceps to penetrate the joint, which can further reduce joint damage.

This time, before Lu Cheng shouted, he washed his hands and gave the straight forceps over, and shouted: "Peeling time: 15:32:26. The operation has begun." ”

Lu Cheng was not nervous, and then pierced the joint space with straight forceps, and expanded the access for the water dispenser and arthroscope to enter.

After talking to the mirror, Lu Cheng finally inserted the arthroscope into the joint space, and there were many details that were needed, for example, when the arthroscope was placed, the knee joint needed to be flexed, and when it continued to go deeper, the knee joint needed to be straightened by flexion......

After finally coming to the infrapatellar space, Lu Chengcheng stopped, and then looked at Lin You, who was already wearing a waterproof suit and went on stage to the opposite side.

"Master, go in. ”

Lin You nodded, probably habitually asking a question: "Do you know why you put the sharp knife down just now?"

"Well, to protect the cartilage of the femur was scratched by a sharp knife. "Every detail of the operation, Lu Cheng naturally understands the reason, otherwise he wouldn't dare to make a move.

"Not bad. Lin You replied with two words, began to rotate the arthroscope and then observed the medial and external gaps.

After seeing the intact anterior and posterior cruciate ligaments, he suddenly asked, "Xiaocheng, do you think I will have surgery for rotator cuff sutures?"

When Lu Cheng heard this strange question, he was immediately stunned.

Then a stream of cold air immediately rises from the tail vertebrae.

Whether Lin You will or not, Lu Cheng doesn't know, because he has never seen Lin You do it.

Then why didn't Lin You do it?

The level is not enough.

Rotator cuff suture is a grade III surgery, and only the title of deputy senior or above.

Although the senior director is qualified, this is not the one who has just entered the half-moon season, and he can be called a senior.

"Master, I understand. Lu Cheng hurriedly admitted his mistake.

"It takes at least ten years to train a doctor. ”

"To ruin a doctor, it only takes hours, even minutes. ”

"So not only do you have to learn the technique professionally, but you also have to be very careful about the classification and grading of the surgery. ”

"We have to remember very clearly which surgeries can be skipped and which ones can't. ”

"Otherwise, you'll play yourself to waste!"

When Lin You said this, he raised his voice a little again, and said, "You are a resident doctor, just cutting a skin and piercing these are completely sufficient and qualified." ”

"Hmm!" Lu Cheng nodded.

He knew who Lin You was saying this to.

Not for him, not for the nurse, not for anesthesia.

but to the patient.

Because the patient of meniscus surgery is epidural anesthesia, he is awake, and he can hear every word in the operating room clearly.

The reason why studying medicine needs to be careful is because the pitfalls in medicine do not only come from diseases......

What Lin You wants to teach as a master, and what Lu Cheng wants to learn as an apprentice is not so simple.

"Follow me to the clinic on Saturday. Wake up early. ”

"Okay!" Lu Cheng didn't dare to speak too loudly now.
