Chapter 2051 I Want to Live Broadcast the Surgery (Leader GZ86LG Plus 4)

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

Director Kong sat aside, frowning.

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

"Ding dong~"

A mission notification sounded in Zheng Ren's ear.

[Urgent mission: A new life that may be abandoned.

Task content: Successfully completed a case of intrauterine interventional surgery.

Task time: 12 hours.

Task rewards: 100,000 experience points, 20,000 skill points, master skill book x 1, lucky value +2. 】

See also the task of adding luck! Zheng Ren was slightly excited.

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

The brand-new surgical procedure, the safety of the mother and child, and the system's stamped certification mean that they can do surgical training after purchasing surgical training time from the system.

In this case, Zheng Ren didn't have to worry about the system operating room being empty and empty after entering.

He lowered his head slightly, pretending to be thinking, and went directly to the system space. Open the system mall, click to buy surgery training time.

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

Surgery is not done under X-rays, but under ultrasound guidance. Ultrasound, Zheng Ren's level is very high.

At least Director Qi of 912 recognized Zheng Ren.

After starting the operation, Zheng Ren discovered a problem, which was the same as the problem of the PICC tube falling off into the heart - he was alone, without an assistant.

MD! Big pig's trotter didn't know how to assign him an assistant, Zheng Ren slandered inwardly.

Although the difficulty is great, it is not like the last operation, which requires the assistant to continuously cooperate with the injection of drugs, and the patient's heart will stop beating if he relaxes for a moment.

Moreover, Zheng Ren's ability to operate with both hands at the same time is very high. It is a bit difficult to do it by himself, but there is no problem.

The ultrasound was placed on the experiment subject's stomach, and began to search for the connection between the fetus and the experiment subject—the umbilical cord blood vessel.

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

But I don't know why, the umbilical cord blood vessels connecting the pregnant woman and the child are very thin. Zheng Ren repeatedly measured it, and it was only about 1.8mm.

The diameter is almost reduced by half, which makes the operation more difficult. It is almost impossible to get a successful puncture.

But for Zheng Ren, who is taller than a mountain after the peak, that's the case.

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

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

You can find the most ideal position when you come up, it is for adult surgery, definitely not for intrauterine surgery.

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

Then Zheng Ren began to use sedative drugs to keep the fetus still for a while, and the fetal movement stopped.

Intrauterine surgery, if the fetus is constantly moving, there is basically no possibility of success. Even if it is successful, you have to fight your luck to see if the child does not move during the operation.

So it is necessary to give birth to the fetus.

The fetus was positioned on the left side, and the fetal abdominal wall, uterus, and left ventricular outflow tract formed a smooth pathway, and Zheng Ren began to insert the guide wire.

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

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

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

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

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

Absolutely not like this, if you do surgery outside in the future, without considering all aspects, come up all at once...

When Zheng Ren thought of this, the sweat dripped down his back.

Start the procedure again and wait for the fetus to transition to the left side again. Puncture and guide wire entry.

In Zheng Ren's view, other people's difficulties were not difficulties at all.

The level of B-ultrasound is master-level, and images can be converted, reconstructed from B-ultrasound to X-ray images and even three-dimensional reconstructed images.

This advantage is unparalleled.

Especially in the intrauterine surgery, compared with other doctors, Zheng Ren had already started the race and was only one step away from the finish line.

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

The second operation went well. The aortic valve stenosis was dilated little by little with a balloon. Ultrasound showed that the transvalvular flow rate of the fetal aorta dropped to 3m/s, and the pressure difference dropped to 36mmHg.

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

At this time, the completion rate of the operation given by Da Zhu Trotter was 96%.

If you stop at this time, there is no problem.

The child can wait in the mother's womb until natural delivery. Although there will be a little problem after birth, it can be expected to wait until the aortic valve operation is done after growing up.

Even so, Zheng Ren was still a little dissatisfied.

He continued to dilate the narrowed aortic valve with slight movements, but it backfired.

The operation time is a hurdle that cannot be overcome.

The sooner it is over, the fewer complications there will be. If you insist on turning the aortic valve stenosis into mild stenosis, it will take too long, and the pregnant woman's uterine cavity will contract once, resulting in a complete failure of the operation.

The precision required for this type of surgery is so high that there is little room for error.

Zheng Ren sighed, and repeated the operation several times. This time he didn't pursue perfection, but just let it go.

The completion rate of the operation is 96%, which is completely acceptable.

The guide wire and balloon were pulled out, and the amniocentesis showed no bloody substance, which meant that neither the pregnant woman nor the child was bleeding.

The operation was successful!

Zheng Ren smiled slightly.

For him, this operation is not as difficult as the operation to remove the PICC catheter performed in the cancer hospital before.

But the significance of intrauterine surgery is extraordinary!

This gives children with congenital heart disease a chance for early treatment!

Counting 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 will occur have all been finalized.

By the 11th to 13th week of pregnancy, congenital heart disease will show its clues. The "Report on the Prevention and Control of Birth Defects in China (2012)" mentioned that there are 130,000 cases of congenital heart disease in children every year, and this is still the data in 2012.

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

And now, this number will further increase for sure. Hundreds of thousands of fetuses need treatment, and clinicians are helpless.

It is of great significance to be able to use interventional surgery to treat children in the uterus. No matter how difficult it is, at least it can give clinicians an idea, instead of giving 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 only have one request - the operation can be performed, but it must be broadcast live."
