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

Director Kong sat aside, frowning.

Director Zhang Lin of the Circulation Department also had the same expression. They were unfamiliar with intrauterine interventional surgery and had no idea.

"Ding Dong~"

A task prompt sound rang in Zheng Ren's ears.

[Urgent Mission: A New Life That May Be Give Up.

Task content: Successfully completed an intrauterine interventional surgery.

Mission time: 12 hours.

Mission reward: Experience value 100,000 points, skill point 20,000 points, master-level skill book x1, lucky value +2.]

I saw another task of adding lucky value! Zheng Renluo was a little excited.

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

The brand new surgery, the safety of the mother and son, and the system cap stamp verification means that you can do surgical training after purchasing the surgical training time by yourself.

In this case, Zheng Ren doesn't have to worry about the system operating room being empty and nothing after entering.

He lowered his head slightly, pretended to think, and went directly to the system space. Open the system mall and clicked to buy the surgical training time.

The system operating room rose from the ground, and Zheng Ren went in directly.

The surgery is not done under X-ray, but is done under ultrasound guidance. Zheng Ren’s level is very high.

At least Director Qi from 912 has recognized Zheng Ren.

After the operation started, Zheng Ren discovered a problem, and the problem of picc tube falling out into the heart was the same as himself, single-handedly without an assistant.

md! The big pig's hoof didn't know how to give him an assistant, Zheng Ren complained in his heart.

However, although it is very difficult, it is not like the last operation. Assistant must constantly cooperate with the injection of drugs. If the patient relaxes a little, the heart will stop beating.

Moreover, Zheng Ren's left and right hands are very high at the same time. It's just a bit difficult to do it by himself, but there is no problem.

Ultrasound was placed on the belly of the experiment subject and began to find the connection between the fetus and the experiment subject.

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

But for some reason, the umbilical cord blood vessels between the pregnant woman and the child in front of me were very thin. Zheng Ren repeatedly measured it, which was only about 1.8mm.

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

But for Zheng Ren, who is even higher than the mountain after the peak, it is just that.

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

Zheng Ren was not in a hurry, knowing that they had to wait.

You can find the ideal location when you come up, which is for adult surgery, definitely not for intrauterine surgery.

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

Then Zheng Ren began to use sedative drugs to prevent the fetus from moving for the time being and stop the fetal movement.

Intrauterine surgery, if the fetus keeps moving, there is basically no possibility of success. Even if it is successful, you have to be lucky, and see if the child moves at all times during the operation.

Therefore, it is necessary to set the fetus.

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

The b-ultrasound determines the position, guidewire, and balloon to the point of congenital stenosis, and Zheng Ren begins to expand the balloon.

I am used to adult surgery, and the balloon is expanded only once, and the surgery is declared a failure.

If the pressure is too high, the fragile blood vessels of the child will explode directly.

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

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

This is absolutely not possible. If you do not take into account all aspects of the surgery outside in the future, you will be able to get up like this...

When Zheng Ren thought of this, the sweat fell on his back.

Start the surgery again and wait again for the fetus to switch to the left position. The puncture is made and the guidewire enters.

In Zheng Ren's opinion, the difficulties of others are not any difficulties at all.

The b-ultrasound level is master level and can convert images, reconstruct them from b-ultrasound to X-ray images or even three-dimensional reconstruction images.

This advantage is unparalleled.

Especially in intrauterine surgery, Zheng Ren, compared with other doctors, was only one step away from the finish line while starting.

For Boss Zheng, the only difficulty is to adapt to the fetal anatomy structure and tube wall hardness and elasticity.

The second operation went smoothly. The balloon was used to expand the aortic valve stenosis little by little. Ultrasound showed that the fetal aortic flow rate dropped to 3m/s and the pressure difference dropped to 36mmhg.

This means that the severe aortic valve stenosis in the child has dropped to moderate to mild.

At this time, the surgery score given by the big pig's hooves was 96%.

If you stop at this time, there will be no problem.

The child can wait for natural delivery in the mother's body. Although there will be a little problem after birth, it is expected to undergo aortic valve surgery when he grows up.

Despite this, Zheng Ren was still a little dissatisfied.

He continued to dilate the narrow aortic valve with a slight movement, but things went against his wishes.

The operation time is a hurdle that has been taken through.

The earlier it ends, the fewer complications will occur. If you insist on turning the aortic valve stenosis into mild stenosis, it will take too long and the uterine cavity of the pregnant woman will contract at one time, resulting in a complete failure of the operation.

The accuracy required for this kind of surgery is so high that the fault tolerance rate is extremely small.

Zheng Ren sighed and repeated several more surgeries. This time he did not pursue perfection, but stopped when he saw the situation.

The completion degree of surgery is 96%, which is completely acceptable.

Pulling out the guidewire, balloon, and amniotic fluid puncture shows no bloody substances, which means that there is no bleeding in pregnant women and children.

The operation was successful!

Zheng Ren smiled slightly.

For him, the difficulty of this surgery was not as difficult as the one I had before when I took a picc catheter in a tumor hospital.

But the significance of intrauterine surgery is extraordinary!

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

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

By the 11th to 13 weeks of pregnancy, congenital heart disease will appear. The "China Birth Defect Prevention and Treatment Report (2012)" mentioned that there are 130,000 children with congenital heart disease every year, which is the data from 2012.

You know, the second child was not open at that time.

Now, this number is growing further. Hundreds of thousands of fetuses needing treatment, but clinicians are helpless.

It is of great significance to be able to use interventional surgery to treat children intrauterine cavity. Regardless of the difficulty, it can at least give clinicians an idea, rather than giving up when they come up.

Zheng Ren came out of the system space, raised his head, and looked Dean Yan in the eyes, "Director, I only have one request for surgery, but I need to broadcast it live."
Chapter completed!
