"Didn't the fetus stop moving after anesthesia?" Xie Ning asked.

"The anesthesia has not started yet, and the fetus will have autonomous actions in the uterus, such as turning over, changing positions, etc.," Lao He explained, "When you change to a satisfactory position of Boss Zheng, the anesthesiologist will start giving the medicine to fix the position of the fetus in the uterus."

“How long will it take?”

"Not necessarily." Lao He said, "When performing a four-dimensional color ultrasound for the fetus, sometimes it takes one or two hours to wait for the fetus to turn over. If you never turn over, you have to wait for the next time. There is a certain probability here, and it is not easy to say when the operation will start."

Just as Lao He said, when the B-ultrasound probe is pressed at a certain position, it no longer moves greatly, but only makes small-scale adjustments.

When the doctor in the b ultrasound room performs four-dimensional color ultrasound for pregnant women, the serious and responsible doctor will wait for a long time and let the pregnant women move.

However, most pregnant women and their families do not understand the meaning, and some even think that doctors who finish the work in a few strokes are higher.

This makes people laugh and cry.

"This is the heart of the fetus. Now the heart of the fetus is only slightly larger than an almond." Lao He made an analogy, holding a laser pen in his right hand and showing Xie Ning the size of the almond with his left hand.

"This is not the space for surgery. Boss Zheng has to use the thinnest guidewire to find the position of the aortic valve, and then push the balloon opens the narrow position."

After a metaphor, the seemingly boring B-ultrasound image has become much more three-dimensional and vivid.

The heart is like almonds, and you must be careful in everything you do. There is nothing difficult to understand.

How difficult the operation is and how high the technical level is required is clearly visible after Lao He's explanation.

There are countless barrages, some people raise questions, and some people tentatively answer them. Lao He took advantage of this period to continue to give Xie Ning a picture of the difficulties of intrauterine interventional surgery.

I said before that this surgery has only been successful in more than 200 cases worldwide, and the difficulty can be imagined.

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

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

When encountering similar pregnant women and children, it is only recommended to induce labor.

There is no chance to try.

Whether from a medical perspective or a commercial perspective, the development and promotion of this technique are of great significance.

Lao He himself has a deep theoretical foundation, especially his B-ultrasound level is very high, and he quotes classics and speaks very well.

He himself said that B-ultrasound can be used to see pneumothorax.

This is a hard bar. Many doctors don’t even know that B-ultrasound can be seen. Only the highest-level Grade A hospital has this kind of business, and only anesthesiologists like Lao He are proficient in this kind of business that seems to be unrelated to anesthesia.

Suddenly, the fetus moved in the uterus. Lao He took a look at the time and the live broadcast of the operation had already passed 34′34″.

I didn't move the whole process just to wait for this moment.

Fortunately, although it took a while, this moment still came.

This is what is called quiet as a virgin.

Seeing Boss Zheng holding the B-ultrasound probe in his left hand and making a gesture with his right hand, Lao He felt envious and jealous.

This is to ask the anesthesiologist of the Women and Children's Hospital to give him anesthesia, and the operation is about to begin.

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

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

The puncture needle is so thin that you will miss it if you don’t look carefully or have a bad look.

Through the pregnant woman's abdominal wall, uterine wall, amniotic cavity, fetal chest wall and other tissue structures, it reaches the fetal left ventricle and fetal aortic valve.

"Uncle Ning, this is the key point of operation." Old He explained step by step, and saw Xie Ning's serious look on his face, he knew that he really understood.

It’s not a family, it’s not a family.

Boss Zheng’s father-in-law is not an ordinary person. The operation he explained was a little more academic than the explanation of this difficult one, but he was a layman who actually understood it!

Old He sighed in his heart, and then saw Boss Zheng send the balloon in.

The balloon is sent to and expanded to open the narrow aortic valve.

Seeing that the balloon began to expand, Lao He's heartbeat began to rise faster.

This is the most critical step, he found relevant reports. Each report only talks about successful cases and does not mention failed surgery.

However, some cases report say that the step of balloon expansion is the most important step. Because there is no relevant standard, the rate of fetal growth in the uterus of pregnant women is not fixed.

So how much power should be used and how much balloon expands to, there is no theoretical basis or data support. We can only do it ideally in the operation and rely on Boss Zheng’s rich experience.

Old He stared at the LED screen tightly. At this moment, he forgot his task and was immersed in the intense operation.

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

Then the balloon expanded slightly, and Lao He immediately felt chest tightness and shortness of breath, as if a balloon was stretched open at his aortic valve.

The entire fetus' heart is as big as an almond, and the balloon is not spread fast, and it is very subtle, very slow, and very slow. If it weren't for the super-b level, Lao He would not be able to determine what Boss Zheng was doing.

What does this have to be precise in operation?!

Lao He sighed in his heart and glanced at the ultrasound data of the fetus.

The pressure difference of the aortic valve began to drop from the peak of 88mmhg. Lao He held a laser pen in his right hand, creaking.

But he didn't notice.

At this moment, Lao He has crossed time and space, and is used to being naturally "standing" on the patient's head of the operating table, staring at the data of the ventilator and monitor.

And while observing countless numbers, I was always watching Boss Zheng’s operations, thinking in my mind what I should do next to perfectly cooperate with Boss Zheng’s surgery.

As the fetal aortic pressure difference narrowed, Lao He saw Boss Zheng continue to expand the balloon.

88mmhg…83mmhg…81mmhg…

The surgery is the most dangerous at this moment.

Once uterine contractions occur or the fetus cannot tolerate balloon dilation and the fetal heart stops beating, laparotomy surgery is required.

75mmhg…64mmhg…

Lao He's heart was in his throat, and Boss Zheng was still expanding his balloon.

His thought was - if it were for himself, he would probably stop expanding the balloon at this time and would stop when he saw it was better.

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

When you have to undergo thoracic surgery after the age of five, it is still too late. Even three years old... two years old... the risk of surgery a few months after birth is lower than now.

But Boss Zheng was unmoved and continued to expand the balloon steadily at a speed that was difficult to distinguish with the naked eye.
Chapter completed!
