Then, will the fetus not move after the anesthesia? "Xie Ning asked.
"The anesthesia hasn't started yet. The fetus will have autonomous movements in the uterus, such as turning over, changing positions, and so on," Lao He explained. "When the position is changed to Boss Zheng's satisfaction, the anesthesiologist will begin to administer the medicine and fix the position of the fetus in the uterus."
"How long will it take?"
"Not necessarily," Lao He said. "When doing a four-dimensional ultrasound on the fetus, sometimes it takes an hour or two to wait for the fetus to turn over. If it doesn't turn over, then we'll have to wait for the next time. There's a certain probability here. It's not easy to say when the surgery will start. "
Just as Lao He had said, the ultrasound probe would no longer move by a large margin once it was pressed on a certain position. Instead, it would only make a small adjustment.
When the doctor in the ultrasound room performed the four-dimensional ultrasound on the pregnant woman, the serious and responsible doctor would wait for a long time and even let the pregnant woman move around in the middle.
However, most of the pregnant women and their families did not understand the meaning behind this. Some even thought that the doctor who finished it with a few strokes was even more skilled.
This made people not know whether to laugh or cry.
"This is the heart of the fetus. Right now, the heart of the fetus is only slightly bigger than an almond." Lao He made an analogy. He held a laser pointer in his right hand and gestured to Xie Ning the size of an almond with his left hand.
"This is not the space for the surgery. Boss Zheng needs to use the thinnest guide wire to find the position of the aortic valve and then use the balloon to open the narrow position."
With a metaphor, the seemingly boring ultrasound image became much more three-dimensional and vivid.
The heart was like an almond. Everything had to be done carefully. This was not difficult to understand.
The difficulty of the surgery and the level of skill required were obvious at a glance under Lao He's explanation.
There were countless bullet screen comments. Some people raised questions, and some tried to answer. Lao He took advantage of this time to continue to teach Xie Ning about the difficulties of intrauterine interventional surgery.
Previously, he had said that there were only more than 200 successful cases of this surgery in the world. One could imagine the difficulty.
Then, Lao He began to introduce how many similar fetuses in the country needed to be treated in a year.
As for this surgery, because it was still in the exploratory stage internationally, many doctors in the country did not even know of its existence.
When encountering similar pregnant women and children, they could only recommend induction of labor.
They did not even have the chance to try.
Whether it was from a medical perspective or a business perspective, the development and promotion of this surgical method was extremely significant.
Lao He himself had a deep theoretical foundation, especially his B-scan level, which was very high. Quoting from classics, what he said was clear and logical.
He himself had said that he could detect pneumothorax with a B-scan.
This was a tough nut to crack. Many doctors did not even know that a B-scan could detect a pneumothorax. Only the highest-level Class Three Grade A Hospitals had this kind of business, and only an anesthesiologist like Lao He was proficient in this kind of business that seemed to have nothing to do with anesthesia.
Suddenly, the fetus in the uterus moved. Lao He looked at the time. The live broadcast of the surgery had already passed 34 ′ 34 ″.
He hadn't moved the entire time just to wait for this moment.
Fortunately, although it took a long time, the moment had finally arrived.
This was the so-called quiet as a virgin.
Seeing Boss Zheng holding the ultrasound probe in his left hand and making a gesture with his right hand, Lao He's heart was filled with envy, jealousy, and hatred.
The anesthesiologist from the Women's and Children's Hospital was going to anesthetize the patient. The surgery was about to begin.
After the anesthesia was complete, Su Yun took the ultrasound probe and began to operate it carefully.
The needle that was as thin as a hair appeared on the screen under the guidance of the ultrasound.
The needle was so thin that if one did not look carefully or if one's eyesight was not good, one would directly miss it.
It passed through the pregnant woman's abdominal wall, uterine wall, amniotic cavity, fetal chest wall, and other tissue structures to reach the fetal left ventricle and fetal heart aortic valve.
"Uncle Ning, this is the main point of the operation." Lao He explained step by step. Seeing Xie Ning's solemn face, he knew that he really understood.
If they were not a family, they would not enter the same door.
Boss Zheng's father-in-law was not an ordinary person. For such a difficult surgery, his explanation was a little more academic, but a layman like him actually understood it!
Lao He sighed in his heart. Then, he saw Boss Zheng send the balloon in.
He sent it into the balloon and expanded it to open the narrow aortic valve.
Seeing that the balloon began to expand, Lao He's heart started to beat faster.
This was the most crucial step. He found the relevant report. Every report only mentioned successful cases and did not mention failed surgeries.
However, some case reports would mention that the balloon expansion step was the most important step. Because there was no relevant standard, the speed at which the fetus grew in the pregnant woman's uterus was not fixed.
Therefore, there was no theoretical basis or data to support how much strength should be used and how much the balloon should be expanded. He could only rely on Boss Zheng's rich experience to complete it during the surgery.
Lao He stared intently at the LED screen. At this moment, he forgot his mission and was immersed in the nervous surgery process.
The ultrasound showed that the balloon had already reached the position of the fetus's narrow aortic valve.
Then, the balloon expanded slightly. Lao He immediately felt his chest tightened and he was short of breath. It was as if a balloon had opened up at his aortic valve.
The entire fetus' heart was the size of an almond. The speed at which the balloon opened up was not fast. It was very, very, very, very slow. If it were not for the ultrasound, Lao He would not have been able to determine what Boss Zheng was doing.
Just how meticulous was his 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 the laser pointer in his right hand and creaked.
However, he did not notice.
At this moment, Lao He had already crossed time and space. He was used to "standing" at the side of the patient's head on the operating table, staring at the data of the ventilator and monitor.
Moreover, while observing the countless values, he had been watching Boss Zheng's operation. In his mind, he was thinking about what he should do next to perfectly cooperate with Boss Zheng's surgery.
As the pressure difference of the fetus' aortic artery narrowed, Lao He saw Boss Zheng continue to expand the balloon.
88mmhg … 83mmhg … 81mmhg …
The surgery was the most dangerous at this moment.
Once there were uterine contractions or the fetus could not withstand the balloon expansion and the fetal heart stopped beating, they would have to perform a laparotomy.
75mmhg … 64mmhg …
Lao He's heart was in his throat. Boss Zheng was still expanding the balloon.
The thought in his heart was — if it were him, he would probably stop expanding the balloon at this moment and stop while he was ahead.
After all, this was the first intrauterine intervention surgery in Asia. Even if the fetus had a small problem, it would still be able to grow up.
There was still time for thoracotomy after the age of five. Even if it was three years old … two years old … a few months after birth, the risk would be lower than now.
However, Boss Zheng was unmoved. He continued to expand the balloon at a speed that was difficult to distinguish with the naked eye.
53mmhg … 49mmhg …
