Chapter 2056 Almond-Sized Heart

"Then after the anesthesia, did the fetus not move?" Xie Ning asked.

"The anesthesia has not yet started, and the fetus will have voluntary movements in the uterus, such as turning over, changing positions, etc." Lao He explained, "When the position is changed to Boss Zheng's satisfaction, the anesthetist will start administering drugs to fix the fetus in the womb. location in the palace."

"How long?"

"Not necessarily." Lao He said, "When doing a four-dimensional color ultrasound for the fetus, sometimes it takes an hour or two to wait for the fetus to turn over. If it still doesn't turn over, then you have to wait for the next time. There is a certain probability here. , It is not very specific to say when the operation can start.”

Just like what 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 doctors in the B-ultrasound room perform four-dimensional color Doppler ultrasound on pregnant women, the serious and responsible doctors will wait for a long time, and will let pregnant women move around in the middle.

But most of the pregnant women and their family members do not understand the meaning, and some even think that doctors who can finish it with just a few strokes have a higher level.

This makes people dumbfounded.

"This is the heart of the fetus. Now the heart of the fetus is only a little bigger than an almond." Lao He made a metaphor, holding a laser pointer in his right hand, and showing Xie Ning the size of an almond with 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 balloon to prop up the narrow position."

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

The heart is like an almond, and everything should be handled with care, which is not difficult to understand.

How difficult the operation is and how high the technical level is required are clear at a glance from Lao He's explanation.

There are countless bullet screens, some people ask questions, and some people try to answer them. Lao He took advantage of this time to continue to explain to Xie Ning the difficulties of intrauterine interventional surgery.

As I said before, this operation has only been successful in more than 200 cases worldwide, so the difficulty can be imagined.

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

And because this surgery is still in the exploratory stage internationally, many doctors in China don't know its existence at all.

When encountering similar pregnant women and children, we can only recommend induction of labor.

Didn't even have a chance to try.

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

Lao He himself has a solid theoretical foundation, especially the high level of B-ultrasound, and he quotes classics, but he speaks clearly and logically.

He himself said that pneumothorax can be seen at the B-ultrasound level.

This is a hard bar. Many doctors don't even know that B-ultrasound can detect pneumothorax. Only the highest-level tertiary hospitals have this kind of business, and only anesthesiologists like Lao He are proficient in this kind of business that seems unrelated to anesthesia.

Suddenly, the fetus moved in the womb. Lao He glanced at the time, 34'34" had passed since the surgery live broadcast.

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

But fortunately, although it has been a little longer, this moment has come.

The so-called quietness is like a virgin, that's it.

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

This is to let the anesthetist of the Women's and Children's Hospital give anesthesia, and the operation will officially begin.

After the anesthesia was completed, 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 the guidance of ultrasound.

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

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 heart aortic valve.

"Uncle Ning, this is the key point of the operation." Lao He explained step by step, and seeing Xie Ning's serious face, he knew that he really understood.

Not a family, do not enter a door.

Boss Zheng's father-in-law is not an ordinary person, and his explanation of this difficult operation is a bit academic, and a layman can understand it!

Lao He sighed inwardly, and then saw Boss Zheng deliver the balloon.

A balloon is delivered and inflated to open the narrowed aortic valve.

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

This is the most critical step, he found relevant reports. Every report only mentions the successful cases and does not mention the failed operations.

However, in some case reports, it will be mentioned that the step of balloon expansion is the most important step. Because there is no relevant standard, the speed of fetal growth in the pregnant woman's womb is also uncertain.

Therefore, there is no theoretical basis or data support for how much force should be used and how far the balloon should be expanded. It can only be done ideally during the operation, relying on Boss Zheng's rich experience.

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

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

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

The heart of the whole fetus is as big as an almond, and the expansion speed of the balloon is not fast, and it is very small, very slow, very slow. If it weren't for the super-high level of B-ultrasound, Lao He wouldn't be able to determine what Boss Zheng was doing.

What kind of fine-grained operation does this have to be? !

Lao He felt emotional and glanced at the ultrasound data of the fetus.

The pressure difference of the aortic valve began to drop from the peak value of 88mmhG. Lao He held the laser pointer in his right hand and creaked.

But he didn't notice.

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

And while observing countless values, he has been watching Boss Zheng's operation, thinking about what he should do next in order to perfectly cooperate with Boss Zheng's operation.

With the reduction of fetal aortic pressure difference, Lao He saw Boss Zheng continue to expand the balloon.

88mmHg...83mmHg...81mmHg...

Surgery is the most dangerous right now.

Once the uterine contraction occurs or the fetus cannot tolerate the balloon expansion, if the fetal heart stops beating, a laparotomy is required.

75mmHg...64mmHg...

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

The thought in his heart was——if it was him, he would probably stop dilating the balloon at this time, and stop it as soon as it was good.

After all, it is the first intrauterine interventional operation in Asia, and the fetus can fully grow up even if there is a little problem.

Wait until after the age of five to have a thoracotomy, everything is still in time. Even at three years old...two years old...a few months after birth, the risk is lower than it is 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...
