Chapter 1632 Correcting the ultrasound scan

Zheng Ren did not show any emotion and did not notice the other party’s rudeness. He inserted the film into the film reader.

It was the same as the x – rays he saw in the system space. There were two X – rays and a three – dimensional CT scan.

The bullet entered about one – third of the area inside the right collarbone. The chest X – ray showed that the bullet was in the shadow of the heart at the lower edge of the heart. There was no hemorrhapsody or pneumothorax.

The position of the collarbone’s fracture had already been fixed with external fixation, and this was very clear.

However, the 3D CT scan did not find the exact location of the bullet.

Zheng Ren took a look at the scan and began to flip through the medical records.

According to the victim, he had leaned forward when he was injured. The other medical histories were of no use to him.

There was still no point in looking through the surgery records of the Affiliated Hospital of the medical University.

Zheng Ren was a little confused.

The vertical x – ray film showed that the bullet was under the shadow of the heart, but the three – dimensional CT image did not show it. This was not a problem of skill level. He did not see the image of the bullet when he reconstructed it in his mind.

The ultrasound of the heart and the conventional four – Chamber ultrasound still did not find the location of the bullet. There was only a slight trisuplete valve reflux.

Zheng Ren hesitated for a moment. According to logic, the bullet had gone missing.

However, the two X – rays showed that the bullet did not change its position.

The patient’s lifeblood was stable. The heart rate was 96 bhp, the blood pressure was 110/70 mmhkg, and the breathing rate was 17 beats per minute. Her electrocardiography, as well as blood indicators such as carcalline protein T, were all normal.

Could it be in his heart? Zheng Ren suddenly had this thought.

He did not see a bullet in a normal ultrasound, so he would try to correct it.

M – Type ultrasound was prone to the phenomenon of distortion of the detection results due to the wrong position of the ultrasonic beam.

There was a specialized research on the problem of directional angle error in ultrasound and the search for a simple and effective method to correct the error, but it was rarely used in clinical practice.

The measurement of the heart’s structural parameters had to follow the law of symmetry. Based on the mathematical principles of the left Chamber’s geometric model, it was proven that there was a functional relationship between the error value and the real value that deviated from the angular orientation, coshorns.

Thus, the mathematical expression of the relevant correction error was created, and a simple method to measure the deviation angle and correct the error with the coshe��function was provided.

Seeing that Zheng Ren was looking at the x – ray silently, Mr. Tian pouted and said coldly,””Chief MA, we can go if old Gu doesn’t want to come. What’s the meaning of you bringing a doctor here?”

“Director Tian, that’s enough!” “This is one of the nominees for this year’s Nobel Prize, Dr. Zheng Ren,” director MA said angrily.”He’s not some random doctor. “

“A Nobel Prize?” Department Director Tian was stunned for a moment, but he still said in disdain,”the one in the Department of interventional services? Nonsense, clinical skills can’t win the Nobel Prize. This is like ...”

Then, he sneered.

“Just like how that group bought an award at the National Music Awards. Show your face and lip – Sync.” The professor beside chief physician Tian said.

Chief MA couldn’t sit still anymore.

In his heart, he thought that this was a high probability thing, but saying it like this in front of the person involved, wasn’t this a slap in the face?

What does it have to do with you whether she’s willing to sing little apple or eat little apple?

If 912 wants to play with these things, then let them play. If you want to do it and have the ability to do it, then do it yourself! What was the point of standing here and directly exposing The Emperor’s New Clothes?

If this matter wasn’t handled well, the two deans would have to come forward in the end.

If things got to that point, and the Ministry was involved ...

Director MA didn’t dare to think any further.

Such disputes had happened two or three times in the past 20 years. Every time it happened, it would shake the entire medical world.

It was great to watch the show from the side, but it was definitely not a pleasant thing to involve himself.

“Chief MA, what’s the meaning of this?” Lin Ge said sinisterly,”comrade Zheng Ren is a member of the health care team. He’s very skilled and has just returned from a mission in Southeast Asia. So, your Affiliated Hospital of the medical University either wanted to have a consultation or couldn’t find the problem, so you called us from 912 to vent your anger?”

“...” Chief MA was helpless.

Damn it, he would definitely find an opportunity to suppress the cardiothoracic Department to the death and let them be so arrogant.

“The CT scan looks fine, but it’s caused by overlapping shadows in the medical imaging. After the correction, we can confirm that the bullet is in the heart. ” Zheng Ren suddenly said indifferently.

Lin Ge was a little hesitant at first. If boss Zheng couldn’t find out where the bullet was, it would be useless no matter how fierce he was.

However, boss Zheng had discovered the bullets and occupied the high ground. He could not kill them!

As for what boss Zheng said, Lin Ge didn’t care. According to his “rich” clinical experience, boss Zheng was never wrong!

Zheng Ren still did not care about what the others were doing. After he found the problem in the 3D reconstruction, he went to the system space, bought the surgery, and entered the system operating theater.

The surgery training began!

The chest was opened up, and the sternum was split open. The buzzing sound of the sternum saw reverberated in the system operating theater.

As Zheng Ren did it, he felt that it was a little dangerous, and the danger might come from Su Yun.

It was such a major surgery, and the bullet was removed from the heart. If he was not called, would he fall out with her?

Let’s not worry about that for now. We have to determine from the anatomical structure that the bullet is in the heart.

He opened the diaphragm, fixed the heart with the octopuses, and cut open the right ventricle.

A Yellow Bullet appeared in his field of vision.

It wasn’t the shrapnel he had imagined, but standard bullets.

The bullet was in the right ventricle membrane. After taking it out, the heart was sutured. When there was no active bleeding, the operation was announced to be over.

The surgery was not difficult for Zheng Ren.

The moment he finished the surgery, another thought suddenly appeared in Zheng Ren’s mind.

It seemed that the bullet could be removed through interventional surgery at this position without opening up the chest.

Zheng Ren was shocked by the outrageous thought.

The originally “simple” surgery had become extremely complicated with this.

Do you want to try?

However, when this thought rose from the bottom of his heart, Zheng Ren could no longer hold back his desire for this strange tactic.

Try it?

Let’s try.

After calming himself down, Zheng Ren recalled the location of the bullet and the possibility of extracting it.

It was still possible.

The patient was lucky that he didn’t suffer any major injuries from the gunshot wound. This was considered a heaven – defying fortune. However, Zheng Ren still wanted to minimize the damage to the overseas staff.

‘Shouldn’t I spend some time experimenting with new surgical methods?’

It should be, and it was very necessary.

Zheng Ren himself was full of respect for these state – owned enterprise employees who worked overseas. Although it seemed a little “wasteful,” the problem could be solved with surgery.

But he still wanted to try.

The surgical method was different from the previous surgical methods. Zheng Ren used a 16-Fr – R E – sheath to perform a puncture in the right femoral vein under the guidance of an ultrasound while the experimental subject was awake and calm.

The guide wire and catheter entered the femoral vein, the inferior vena cava, and finally the right ventricle.
