Chapter 2052

"Zheng Ren, are you sure?" Dean Yan asked seriously.

Director Kong sat aside, frowning.

Zhang Lin, director of the circulatory department, has the same expression. They are very strange to intrauterine interventional surgery and have no idea.

"Ding Dong ~"

Zheng Ren heard the task prompt sound.

[urgent task: a new life that may be abandoned.

Task content: one case of intrauterine interventional surgery was successfully completed.

Task time: 12 hours.

Task reward: 100000 experience points, 20000 skill points, master level skill book × 1, lucky value + 2.]

See the task of adding lucky value again! Zheng renlue was a little excited.

Compared with the lucky value, Zheng Ren looks forward to the success of intrauterine interventional surgery.

The brand-new operation, the safety of mother and son, and the system stamping certification mean that you can do surgical training after you buy the operation training time in the system.

In this case, Zheng Ren doesn't have to worry. After entering the system, the operating room is empty and there is nothing.

He bowed his head slightly, pretended to think, and went directly to the system space. Open the system mall and click to buy operation training time.

The system operating room sprang up and Zheng Ren went straight in.

The operation was not performed under X-ray, but under ultrasound guidance. Ultrasound, Zheng Ren's level is very high.

At least 912 director Qi has recognized Zheng Ren.

After starting the operation, Zheng Ren found a problem, which was the same as the problem of PICC tube falling off into the heart - he was alone and had no assistant.

MD！ Big pig hoof didn't know to equip himself with an assistant. Zheng Ren was disgusted.

However, although the difficulty is great, it is not like the last operation. The assistant must constantly cooperate with the injection of drugs. Once the patient's heart is relaxed, the patient's heart will stop beating.

And Zheng Ren's level of simultaneous operation of left and right hands is very high. It's just difficult to do it alone, but there's no problem.

Ultrasound set up on the belly of the experimental body and began to look for the connection between the fetus and the experimental body - umbilical cord blood vessels.

At 32 weeks of gestation, the umbilical cord blood vessels should be about 3-4mm.

But I don't know why. The umbilical cord blood vessels are very thin in the connection between pregnant women and children. Zheng Ren repeatedly measured it, which is about 1.8mm.

Almost half the diameter was narrowed, which made the operation more difficult. It is almost impossible to succeed in one puncture.

But for Zheng Renlai, who is taller than ever after the peak, that's the case.

Waiting for the fetus to turn over and change position takes a long time.

Zheng Ren is not in a hurry. He knows that he must wait.

You can find the most ideal position when you come up. It's an adult operation, definitely not an intrauterine operation.

After 23 ′ 12 ", the child finally changed to a position satisfactory to Zheng Ren. He punctured directly and hit the nail on the head.

Then Zheng Ren began to use sedative drugs to stop the fetus temporarily.

Intrauterine surgery, if the fetus moves constantly, there is basically no possibility of success. Even if it is successful, we should try our best to see whether the child moves during the operation.

So it is necessary to give the fetus a place to live.

On the left side of the fetus, the fetal abdominal wall, uterus and left ventricular outflow tract formed a smooth path, and Zheng Ren began to slide the guide wire in.

When the position was determined by B-ultrasound, the guide wire and balloon came to the point of congenital stenosis, Zheng Ren began to expand the balloon.

Accustomed to adult surgery, the balloon was expanded only once, and the operation failed.

Too much pressure, children's fragile blood vessels directly burst.

Zheng Ren knew that he was careless, perhaps because he was in the system operating room.

This is quite bad. Zheng Ren immediately made a self-examination.

Absolutely not. If you have surgery outside in the future, you don't consider all aspects and come up so suddenly

Zheng Ren thought of this, and the sweat on his back came down.

Start the operation again and wait for the fetus to change to the left position again. Puncture and guide wire entry.

In Zheng Ren's view, the difficulties of others are not at all difficult.

B-ultrasound is a master level, and it can convert images from B-ultrasound to X-ray images or even 3D reconstructed images.

This advantage is unparalleled.

Especially in intrauterine surgery, compared with other doctors, Zheng Ren had already started at the same time and was only one step away from the end.

For boss Zheng, the only difficulty is to adapt to the anatomical structure of the fetus and the hardness and elasticity of the tube wall.

The second operation was very successful. A little bit of balloon was used to expand the position of aortic stenosis. Ultrasound showed that the fetal aortic cross valve velocity decreased to 3m / s and the pressure difference decreased to 36mmhg.

This means that the severe aortic stenosis has been reduced to moderate to mild.

At this time, the operation completion rate given by the big pig hoof is 96%.

If you stop now, there's no problem.

Children can wait in the mother until natural delivery. Although there will be a little bit of problems after birth, it can be expected to wait until you grow up to have aortic valve surgery.

Nevertheless, Zheng Ren is still a little dissatisfied.

He continued to dilate the narrow aortic valve with a slight movement, but it backfired.

The operation time is an insurmountable barrier.

The sooner it ends, the fewer complications. If you insist on turning the aortic stenosis into mild stenosis, it will take too long, and the uterine cavity of pregnant women will contract once, resulting in complete failure of the operation.

The precision required for this operation is so high that the fault tolerance rate is very small.

Zheng Ren sighed and repeated the operation several times. This time he didn't pursue perfection, but just accept it when it's good.

The surgical completion rate was 96%, which was completely acceptable.

Pull out the guide wire and balloon, and amniocentesis shows that there is no blood substance, which means that there is no bleeding in pregnant women and children.

The operation was successful!

Zheng Ren smiled.

For him, this operation is not as difficult as the previous operation to take PICC catheter in cancer hospital.

But the significance of intrauterine surgery is extraordinary!

This gives children with congenital heart disease an opportunity for early treatment!

From implantation to the 8th week of pregnancy, the fetal heart development is basically finalized. Whether the fetal heart is normal, whether congenital heart disease will occur, and what problems it will be have been finalized.

By the 11th to 13th weeks of pregnancy, congenital heart disease will show signs. According to the report on the prevention and treatment of birth defects in China (2012), there are 130000 children with congenital heart disease every year, which is still the data in 2012.

You know, there was no second child at that time.

Now, it is certain that this figure has increased further. Hundreds of thousands of fetuses need treatment, but clinicians are helpless.

It is of great significance to use interventional surgery for intrauterine treatment of children. No matter how difficult it is, it can at least give clinicians an idea, rather than give up when they come up.

Zheng Ren came out of the system space, raised his head and looked directly into Dean Yan's eyes. "Dean, I have only one requirement - surgery can be done, but it should be broadcast live."
