The road to the rise of great doctors

Chapter 23 Good News
"Look here, is it thicker and fuller than the others?" Song Wei pointed at a few tubes with tweezers, and then said: "This is the seminiferous tubule. This kind of relatively thick and full one is easier to find mature ones. of reproductive cells."

There are generally two ways to obtain spermatogenic tissue during surgery, one of which is the seminiferous tubules mentioned just now, and the other is the egg tissue obtained by the surgeon using microscissors on the table.The former requires higher technology and experience.Liu Dong's current method of surgery is to remove the seminiferous tubules.

Song Wei put the removed seminiferous tubules into a pre-prepared petri dish filled with culture medium, and his assistant Wang Jie handed it to the waiting embryonic laboratory technicians, made tissue suspension and observed it under a microscope , look for mature germ cells.

"I found it, and there are still a few swimming around." Xiao Zhao, the technician, said to Song Wei after finding out.

After hearing this, Song Wei said, "Okay, I'm not busy with this station today. I'll find a few more and send them to the woman for backup."

The choice of assisted reproduction plan is divided into two types according to the time of the woman's egg retrieval cycle, one is synchronous and the other is asynchronous.

Synchronous means that the man will collect the reproductive cells on the day the woman retrieves her eggs or the day before. If they are retrieved, fresh reproductive cells will be used for the next step of assisted reproduction. If they cannot be retrieved, they will decide after the couple fully understands the doctor's advice. Is it egg freezing or using donated germ cells for the next step of assisted reproduction at the same time?The advantage of synchronization is that it is used fresh and does not need to go through the freezing and resuscitation process, which can reduce the risk of damage.The disadvantage is that if it cannot be obtained, you need to freeze eggs or use donor sperm to assist pregnancy.

Asynchronous means that the man takes the germ cells first, and if they are successfully obtained, they are frozen.Waiting for the woman’s egg retrieval day to thaw and revive the male’s reproductive cells.The advantage of asynchronous is that it avoids the physical and psychological damage and financial costs caused by using ovulation induction drugs and egg retrieval surgery on the woman without being sure whether male germ cells have been obtained.The disadvantage is that the technical requirements for the embryonic laboratory of the reproductive center are relatively high, and not all centers have the conditions to operate in this way. In addition, the male germ cells that are thawed and resuscitated may be lost. If the basic conditions are poor, they may not be used or the amount may be small, resulting in subsequent problems. The failure rate increases during assisted pregnancy.

Fortunately, the couple was lucky. The woman had no disease and passed all previous medical examinations.Although the man has a disease, currently, the number and vitality of the tadpoles swimming around can be found, which is already considered outstanding compared to people with the same disease.In this case, the probability of successful assisted pregnancy will be high!
"Okay, call it a day." Song Wei said.The operation went smoothly, and Song Wei was in a happy mood.

Before closing, the surgeons and nurses began to check whether the number of instruments and auxiliary materials were complete. After confirmation, the closure officially began.

He stopped the bleeding points one by one again, and after checking that there were no new bleeding points, Song Wei began to close them layer by layer.

Because Wang Jie and Liu Dong have communicated with Song Wei before, Liu Dong will be the first assistant in the next four operations. These are operations performed by two people.

Therefore, Wang Jie is responsible for sending patients back to the ward, writing medical records and issuing medical orders. If there is anything going on in the ward, Wang Jie will handle it first.

After replacing the new auxiliary materials and supplementing the used consumables, the roving nurse, urged by Song Wei, brought in the next patient waiting at the door of the operating room.

Liu Dong is about to participate in microsurgery, but he is not nervous at all.

During the three weeks before and after the urology surgery, Liu Dong has participated in many operations and has been baptized by emergency surgeries. Even if it is his first time to participate in microsurgery, he is still confident that he will perform well. .

After seeing the anesthetist start pushing medicine and putting on a mask to inhale oxygen on the patient, Liu Dong went out to brush his hands.When he came in again, the anesthetist just finished the anesthesia.Liu Dong picked up the sterilization bowl from the auxiliary cart next to the operating table, and the nurse poured iodine on it, then began to disinfect the perineum, spread drapes, and put on surgical gowns.

Song Wei stood aside and watched carefully. If there was any improper operation, he might severely correct him!After watching for a few minutes, he said: "Liu Dong, the disinfection and draping of the next few units will be carried out according to this time. It has passed the test."

After the operation started, Song Wei took Liu Dong along the established surgical incision, incised and separated it layer by layer.

Liu Dong plays the role of Wang Jie on the previous one, but from the operation, it can be found that Liu Dong is more proactive and has a higher degree of cooperation.Basically, wherever the surgeon's knife goes, Liu Dong, the first assistant, performs operations such as exposure, hemostasis and suction.It fully shows that this is the standard for a qualified first assistant: being familiar with every step of the surgical operation, having a pre-judgment for the surgeon's next operation, and having a strong concept of sterility.

This second patient found the seminiferous tubules that met the requirements after searching for two eggs.

The previous one was relatively lucky, but this one is the majority. The operation time will be longer, and the post-operative swelling and other symptoms will be different.This is the same kind of surgery, some end early and some end late.Some people are fine after the operation, and some can't get out of bed after the operation.Everyone's post-operative experience is not the same, because the name of the surgery is the same, the specific operations are different, and everyone's physical condition and disease are also different.

After the bleeding was stopped and the tunica albuginea was sutured, Liu Dong took the initiative and said: "Teacher Song, you have to do a few more surgeries today. I am very skilled in this kind of skin-subcutaneous suturing. Why don't you first see if I can do it?" Are you coming again?"

Song Wei no longer has any need to complete this kind of surgery, so he is happy to give young people a chance.

I saw him saying "Okay" and handing the needle holder and tweezers to Liu Dong. I saw Liu Dong operating it smoothly. Although each needle was not fast, under this rhythm, the spacing was balanced. , without any unnecessary movements, the whole thing was completed a few minutes faster than the combination of Song Wei and Wang Jie just now.

The next two microscopy surgeries followed similar steps to search for germ cells. The third one searched through both sides of the balls but still couldn't find them. It took almost as much time as the first two machines combined, but this is fate.The fourth unit continued the success of the first two units.

After finishing 4 sets, it was already noon, Song Wei and Liu Dong left the operating room and went to eat a work box lunch during the interval between dressing change in the operating room and anesthesia performed by the anesthesiologist.

Next, they have to undergo a major surgery!Microsurgery is a difficult operation...

Liu Dong looked at the progress of the task (9/10). It should be completed today. The abdominal closure surgery should be very useful for the next department to be rotated - general surgery!
