Zhao Heng moved the ultrasound probe while looking at the images on the B-ultrasound screen next to the bed, and kept restoring and reconstructing the patient's anatomical three-dimensional structure in his mind.

This ability only slowly emerged after he picked up the skills and experience of many surgeons and fused them all.

As a surgeon, the requirements for space and distance are very high.

You know, in many cases, there is not enough field of vision for surgery, and in this case, it is necessary to rely on the surgeon's spatial perception.

To be a good surgeon, you can have some of these abilities.

The surgeon's surgical experience naturally includes the experience and experience of spatial cognition and perception.

And Zhao Heng, who has integrated so much experience as a surgeon, has outstanding ability in spatial perception.

Looking at Zhao Heng's operation, everyone present was a little confused, and they didn't know what Zhao Heng was doing.

Soon, Zhao Heng's three-dimensional modeling in his mind was completed.

"It's okay, the B-ultrasound can be pushed over."

Zhao Heng felt that the three-dimensional anatomical modeling in his mind had been basically completed, and said to nurse Xiaoli.

"Well, okay, Dr. Zhao."

Xiaoli hurriedly took the B-ultrasound probe in Zhao Heng's hand, put it on the B-ultrasound instrument, and pushed the B-ultrasound instrument aside.

"Zhanpeng, Wang Chao, next you fix the patient's position, especially no shaking."

Zhao Heng said to Zhanpeng and Wang Chao, who were standing on both sides of the operating table, supporting the super mother, who were already very struggling and laborious.

"Okay."

Zhan Peng and Wang Chao replied in unison.

No matter what kind of thoughts they had, at this time, it was impossible for them to go against Zhao Heng.

"Prepare the needle."

Zhao Heng said to nurse Xiaohong again.

"What?!"

Hearing Zhao Heng ask the nurse to prepare the puncture needle, He Wei couldn't help but exclaim.

You must know that the biggest problem with anesthesia for this heavyweight pregnant woman is that after the fat layer on the back of the mother, the current puncture needle cannot penetrate, and since the distance is not enough, it is naturally impossible to reach the epidural space and inject anesthetic drugs.

"Doctor Zhao, do you want to change to something else, the length of this puncture needle doesn't seem to be enough."

He Wei couldn't help but ask suspiciously.

"Yesterday I went to the instrument room of the operating room to see it, and this 8.5cm puncture needle is already the longest."

Zhao Heng shook his head slightly and said.

"The patient's fat layer is as high as 10cm, and if the puncture needle is only 8.5cm, this distance is not enough, how can it be punctured?"

He Wei asked the doubts in the hearts of everyone present at this time.

"The patient's fat layer is indeed 10cm, but through this lateral decubitus position, the skin on the patient's back is tightened, which reduces the position of at least 1cm, and the patient's fat layer is relatively loose, and it can be shortened by squeezing, which is enough."

Zhao Heng explained slowly.

As soon as he said this, He Wei and everyone present suddenly realized.

Fine, this operation is so fine!

Everyone looked at Zhao Heng and couldn't help but sigh.

"And what about body markings?"

He Wei asked suspiciously.

In the face of this super fat man, the body surface signs that ordinary people will appear on this patient are almost invisible.

Without the guidance of body surface landmarks, it is simply impossible to determine the exact location of the puncture.

"Through the B-ultrasound test just now, I have basically established the local anatomical model of the patient, and this position can still be found."

Zhao Heng explained simply.

"This..."

He Wei was shocked by Zhao Heng's words.

Just now, the resident doctor Xiao Huang was still saying that the human brain is not a computer, and it is impossible to build a three-dimensional model in the human brain.

I didn't expect this to be slapped in the face so quickly.

This Zhao Heng, who is sacred?!

At this moment, He Wei couldn't help but sigh in her heart.

Soon, nurse Xiaohong pushed the workbench with the needle over to the table.

Zhao Heng put on gloves and picked up the puncture needle from the workbench, while nurse Xiaohong Xiaoli disinfected the skin and laid out a hole towel.

The most critical puncture was about to begin, and everyone in the operating room stared at Zhao Heng tightly, not daring to blink their eyes.

In the eyes of others, this patient is a mountain of meat, not to mention finding the exact puncture position, or being able to basically distinguish the anatomical position and structure, which is already very laborious.

But Zhao Heng is going to blind wear in this very difficult situation.

To puncture in this case, it is necessary to have a special feeling that pierces the fog.

This feeling is spatial perception.

Everyone has spatial perception, but to varying degrees.

Spatial perception refers to the perception of spatial characteristics such as distance, shape, size, and orientation of objects.

The most common intuitive is the sense of direction.

Just like applying for the pilot, you must take the test of spatial perception, this test is to fix the test person on the centrifuge, and then rotate at high speed, and after stopping, the test subject must accurately say the four directions of south, south, west, and north.

In real life, some people can't even tell the difference between left and right, let alone this level of spatial perception.

It can be said that this is a rare ability that very few people have!

"Hold down both sides of this position."

The three-dimensional model in Zhao Heng's mind continued to operate, allowing him to determine the exact location of a puncture, and after it was determined, Zhao Heng said to nurses Xiaoli and Xiaohong.

"Well, okay, Dr. Zhao."

Nurses Xiaoli and Xiaohong hurriedly stepped forward, stood on both sides of Zhao Heng, and squeezed both sides of the position Zhao Heng said.

Think about it, a big fat man is lying on the operating table, two people are supporting on both sides, and two nurses are squeezing the thick fat with all their might before they can perform the final puncture.

That's a lot of work!

Zhao Heng took a deep breath, picked up the puncture needle, aimed it at the position, and stabbed it in, without a slight pause, and he was sure of the essence of being ruthless.

As a doctor is like this, the preparation time may be much longer than the actual operation time.

It can be said that success or failure is in such a moment.

Life and death in an instant is something that is often encountered in the profession of doctors.

Seeing that Zhao Heng didn't pause or hesitate at all, he directly inserted the needle, and everyone present paused.

For fear that making a little sound would affect Zhao Heng, as long as Zhao Heng's hand shook slightly, this anesthesia could be said to have failed!

Laugh at!

When the puncture needle entered a place, Zhao Heng seemed to hear the sound of the puncture needle piercing the periosteum.

He was now quite sure that the needle had entered the epidural space.

Thinking of this, he pulled out the puncture needle in the sleeve needle, turned his head and said to He Wei: "Doctor He, please take the anesthetic." ”

Obviously, nurses Xiaoli and Xiaohong must squeeze the patient's fat at all times, otherwise, the thick fat will push out the needle that has entered the cavity in an instant.

"Okay."

Hearing Zhao Heng's call, He Wei immediately nodded, put on gloves, picked up the syringe, took a tube of anesthetic, and handed it to Zhao Heng.

"Thank you."

Zhao Heng said casually, and then injected the anesthetic into the cavity along the trocar.
