Chapter 2057

"Did the fetus stop moving after anesthesia?" Xie Ning asked.

"Anesthesia has not started yet. The fetus will have autonomous movements in the uterus, such as turning over, changing position and so on." Lao he explained, "when you change to a position satisfactory to boss Zheng, the anesthesiologist begins to give drugs to fix the position of the fetus in the uterus."

"How long will it take?"

"Not necessarily." Lao he said, "when giving the fetus four-dimensional color Doppler ultrasound, sometimes it takes an hour or two to wait for the fetus to turn over. If you don't turn over all the time, you have to wait for the next time. There is a certain probability. It's not very easy to say when you can start the operation."

As Lao he said, if the B-ultrasound probe is pressed at a certain position, it will no longer move greatly, but only make small-scale adjustment.

When doctors in B-ultrasound room do four-dimensional color Doppler ultrasound for pregnant women, serious and responsible doctors will wait for a long time and let pregnant women move in the middle.

However, most pregnant women and their families do not understand the meaning, and some even think that the doctors who finish it with a few strokes have a higher level.

This makes people laugh and cry.

"Here is the fetal heart. Now the fetal heart is only a little bigger than an almond." Lao he made an analogy, holding a laser pen in his right hand and comparing the size of almonds to Xie Ning in his left hand.

"This is not the space for surgery. Boss Zheng needs to use the thinnest guide wire to find the position of the aortic valve, and then use the lower balloon to open the narrow position."

With a metaphor, the seemingly boring B-ultrasound images have become more three-dimensional and vivid.

The heart is like an almond. You should be careful in all operations, which is not difficult to understand.

The difficulty of the operation and the required technical level are clear at a glance under Lao he's explanation.

There were countless bullets. Some people asked questions and others tried to answer them. Lao he took advantage of this time to continue to give Xie Ning popular science about the difficulties of intrauterine interventional surgery.

As mentioned before, this operation has only succeeded in more than 200 cases worldwide, and the difficulty can be imagined.

Then Lao he began to introduce how many similar fetuses in China would need treatment in a year.

Because this operation is still in the exploratory stage internationally, many domestic doctors do not know its existence at all.

In case of similar pregnant women and children, induction of labor can only be recommended.

I don't even have a chance to try.

Whether from a medical point of view or from a commercial point of view, the development and promotion of this operation is of great significance.

Lao he himself has a deep theoretical foundation, especially the high level of B-ultrasound and quotes scriptures.

He himself said that B-ultrasound can see pneumothorax.

This is a hard bar. Many doctors don't even know that b super can see pneumothorax. Only the top-level third-class hospitals have this business, and only anesthesiologists like Lao he are proficient in this kind of business that seems not related to anesthesia.

Suddenly, the fetus moved in the uterus. Lao he took a look. The live broadcast of the operation has passed 34 ′ 34 ″.

Don't move all the way, just to wait for this moment.

But fortunately, although it took a long time, this moment came.

The so-called quiet if virgin, that's it.

Seeing boss Zheng holding a B-ultrasound probe in his left hand and making a gesture in his right hand, Lao he felt all kinds of envy, jealousy and hatred.

This is to ask the anesthesiologist of the women's and children's hospital to give anesthesia. The operation will officially begin.

After anesthesia, Su Yun took over the B-ultrasound probe and Zheng Ren began to operate carefully.

A puncture needle as thin as a hair appears on the screen under ultrasound guidance.

The puncture needle is so thin that if you don't look carefully or have bad eyes, you'll miss it directly.

Through the abdominal wall, uterine wall, amniotic cavity, fetal chest wall and other tissue structures of pregnant women, it reaches the fetal left ventricle and fetal heart aortic valve.

"Uncle Ning, this is the focus of the operation." Lao he explained step by step. Seeing Xie Ning's dignified face, he knew he really understood.

Not a family, don't enter a house.

Boss Zheng's father-in-law is not an ordinary person. His explanation of this difficult operation is a little academic. A layman can understand it!

Lao he sighed in his heart, and then saw boss Zheng send the balloon in.

The balloon was introduced and dilated to open the narrow aortic valve.

Seeing that the balloon began to expand, Lao he's heart began to beat faster.

This is the most critical step for him to find relevant reports. Every report only said successful cases, without mentioning failed operations.

However, some case reports will say that balloon expansion is the most important step. Because there is no relevant standard, the speed of fetal growth in pregnant women is uncertain.

Therefore, there is no theoretical basis and data support for how much force should be used and to what extent the balloon should be expanded. We can only rely on boss Zheng's rich experience to complete the operation.

Lao he stared at the LED screen tightly. At this moment, he forgot his task and the whole person was immersed in the tense operation process.

B-ultrasound showed that the balloon had reached the position of fetal narrow aortic valve.

Then the balloon expanded slightly. Lao he immediately felt his chest tightness and shortness of breath. It seemed that a balloon was opened at his aortic valve.

The whole fetal heart is the size of an almond. The balloon is not opened fast, and it is very subtle, very slow, very slow. But for the high level of B-ultrasound, Lao he couldn't be sure what boss Zheng was doing.

This has to be right. What's the operation like?!

Lao he sighed and glanced at the ultrasound data of the fetus.

The aortic valve differential pressure began to decrease from the peak of 88mmhg. Lao he held the laser pen in his right hand and creaked.

But he didn't notice.

At this moment, Lao he has crossed time and space and is used to "standing" on the head side of patients on the operating table, staring at the data of ventilator and monitor.

And while observing countless values, I have been watching boss Zheng's operation and thinking about what I should do next to perfectly cooperate with boss Zheng's operation.

With the narrowing of fetal aortic pressure difference, Lao he saw boss Zheng continue to expand the balloon.

88mmHg……83mmHg……81mmHg……

Surgery is the most dangerous at the moment.

Once there is uterine contraction or the fetus cannot tolerate balloon dilatation and the fetal heart stops beating, laparotomy is necessary.

75mmHg……64mmHg……

Lao he's heart all mentioned his voice, and boss Zheng is still expanding the balloon.

The idea in his mind was that if he changed to himself, he might stop expanding the balloon at this time and accept it when he saw it.

After all, it is the first intrauterine intervention in Asia. Even if the fetus has a little problem, it can grow up completely.

When you are five years old, you can have a thoracotomy. Everything is still in time. Even at the age of three... Two... A few months after birth, the risk of reoperation is lower than now.

But boss Zheng was unmoved and continued to expand the balloon at a speed that was difficult to distinguish with the naked eye.

53mmHg……49mmHg……
