"Zheng Ren, are you sure?" Dean Yan asked seriously.
Director Kong sat aside with a sad face.
Director Zhang Lin from the Circulation Department also had the same expression. They were all unfamiliar with intrauterine interventional surgery and had no idea.
"Ding dong~"
A mission reminder sounded in Zheng Ren's ears.
Urgent mission: a new life that might have been abandoned.
Task content: Successfully completed an intrauterine interventional surgery.
Mission time: 12 hours.
Mission reward: 100,000 experience points, 20,000 skill points, master level skill book × 1, luck value +2.
See the task of increasing luck again! Zheng Ren was slightly excited.
Compared with luck, Zheng Ren was more looking forward to the success of the intrauterine interventional surgery.
The brand-new surgical technique, the safety of the mother and child, and the system stamping and certification means that you can do surgical training after purchasing surgical training time from the system.
In this case, Zheng Ren doesn't have to worry about finding the system operating room empty with nothing after entering.
He lowered his head slightly, pretended to think, and came directly to the system space. Open the system mall and click to purchase surgical training time.
The system operating room rose from the ground, and Zheng Ren got directly into it.
The surgery is not done under X-ray, but under ultrasound guidance. Ultrasound, Zheng Ren's level is very high.
At least Director Qi from 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 working alone without an assistant.
MD! Big Pig Hotter didn't know how to assign himself an assistant, Zheng Ren cursed in his heart.
However, although it is difficult, it is not like the last operation. The assistant must continuously cooperate with the injection of drugs. The patient's heart will stop beating if he relaxes for a moment.
Moreover, Zheng Ren's ability to operate both his left and right hands at the same time is very high. It is a little difficult to do it by himself, but there is no problem.
The ultrasound was placed on the subject's belly and began to search for the connection between the fetus and the subject - the umbilical cord blood vessels.
At 32 weeks of pregnancy, the umbilical cord blood vessels should be about 3-4mm.
But for some unknown reason, the umbilical cord blood vessels connecting the pregnant woman and the patient in front of her were very thin. Zheng Ren repeatedly measured it, and it was only about 1.8mm.
The diameter was narrowed by almost half, which made the operation more difficult. It is almost impossible to achieve a successful puncture.
But for Zheng Ren, whose mountain after the peak is higher than the other, that's all.
Waiting for the fetus to turn over and change positions took a long time.
Zheng Ren was not in a hurry, knowing that everything had to wait.
You can find the most ideal position when you come up. That 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.
Zheng Ren then began to use sedative drugs to stop the fetus from moving for the time being, and the fetal movement stopped.
Intrauterine surgery has basically no chance of success if the fetus keeps moving. Even if it is successful, it still depends on luck and depends on whether the child moves during the operation.
Therefore, it is necessary to stabilize the fetus.
On the left side of the fetus, the fetal abdominal wall, uterus, and left ventricular outflow tract formed a smooth path, and Zheng Ren began to insert the guide wire.
B-ultrasound determined the position, the guide wire and balloon reached the point of congenital stenosis, and Zheng Ren began to expand the balloon.
As is customary to adult surgeries, the balloon only expanded once and the surgery failed.
If the pressure is too high, the child's fragile blood vessels will burst.
Zheng Ren knew that he was careless, maybe because he was in the system operating room.
This was quite bad, and Zheng Ren immediately made a self-examination.
This must not be the case. If we perform surgery outside in the future and do not consider all aspects, it will happen all at once...
When Zheng Ren thought of this, sweat started to pour down his back.
Start the operation again and wait for the fetus to transition to the left side. Puncture and guide wire entry.
In Zheng Ren's opinion, other people's difficulties are not difficulties at all.
The B-ultrasound level is master-level, and it can convert images from B-ultrasound reconstruction to X-ray images or even three-dimensional reconstructed images.
This advantage is unparalleled.
Especially in intrauterine surgery, Zheng Ren, compared with other doctors, had already started and was only one step away from reaching the finish line.
For Boss Zheng, the only difficulty is adapting to the anatomy of the fetus and the hardness and elasticity of the tube wall.
The second operation went smoothly. A balloon was used to expand the stenosis of the aortic valve bit by bit. The ultrasound showed that the fetal aortic transvalvular flow velocity dropped to 3m/s and the pressure difference dropped to 36mmHg.
This means that the child's severe aortic valve stenosis has been reduced to moderate to mild.
At this time, the operation completion rate given by Big Pig Hoof was 96%.
If you stop now, there will be no problem.
Affected children can wait in the mother's womb until natural delivery. Although there will still be some minor problems after birth, it is expected that the patient will undergo aortic valve surgery when he grows up.
Even so, Zheng Ren was still a little dissatisfied.
He continued to use slight movements to dilate the narrowed aortic valve, but it backfired.
The operation time is an insurmountable hurdle.
The sooner it's 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 at once, resulting in a complete failure of the operation.
The precision required for this kind of surgery is so high that there is little room for error.
Zheng Ren sighed and repeated the operation several more times. This time he didn't pursue perfection, but just quit when it was good.
The surgery completion rate was 96%, which is completely acceptable.
The guide wire and balloon were pulled out, and the amniocentesis showed no bloody material, which meant that neither the pregnant woman nor the child was bleeding.
The operation was successful!
Zheng Ren smiled slightly.
For him, this operation was not as difficult as the previous operation to remove the PICC catheter at the cancer hospital.
But the significance of intrauterine surgery is extraordinary!
This gives children with congenital heart disease an opportunity 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 it will cause have all been determined.
By the 11th to 13th week of pregnancy, congenital heart disease will show signs. The "China Birth Defects Prevention and Treatment Report (2012)" mentioned that there are 130,000 children with congenital heart disease every year, and this is still the data in 2012.
You know, the second child was not allowed at that time.
Now, this number is certain to grow further. Hundreds of thousands of fetuses need treatment, but clinicians are helpless.
It is of extraordinary significance to be able to perform intrauterine treatment on children with interventional surgery. No matter how difficult it is, it can at least give clinicians an idea instead of giving up right away.
Zheng Ren came out of the system space, raised his head, and looked directly into Dean Yan's eyes, "Dean, I have only one request—the surgery can be performed, but it must be broadcast live."
