The deepest root of the tumor has not yet been fully dug out, and the last adhesions with the nerve nucleus have not yet been separated.

The ballet on the tip of the knife continued, and the scalpel, which had already undergone three death threats, did not flinch and continued to move forward.

The last adhesion has already crossed the shallow layers of the nucleus, deeper than the previous time, the previous time it was peeled off, this time it was dug out.

Yang Ping knew in his heart that the first three dangers were not the most thrilling, and the next cardiac arrest was completely different from the previous one.

Once there is cardiac arrest, it cannot be rescued immediately, and if the operation is to be successful, he must complete the last danger zone separation on the basis of Professor Feng's cardiac arrest.

In other words, after cardiac arrest, he must wait for the successful completion of the operation before he can be rescued.

If his surgery is not successfully completed, there will be no chance of rescue, and if his operation takes too long, even if the operation is completed, the best opportunity for rescue will be lost.

The time for the brain to tolerate ischemia is only 4-6 minutes, and there is still time for everyone to rescue.

Yang Ping calculated that there were only sixty seconds left for his heart arrest surgery.

These 60 seconds will be under tremendous pressure to complete the operation accurately and accurately in the most dangerous areas within the time limit.

This kind of test, if it weren't for the strong mental quality cultivated by countless devils, there would be no way at all, and it would be almost hopeless.

Johanneson has been tortured to death, if he is a layman, it's okay, it doesn't hurt or itch, look at the excitement, as the world's top neurosurgeon, almost every step is clear.

Every time Yang Ping operated, the laser knife was like operating on the tip of Johannathan's heart, and he could almost feel his heart expand and contract strongly.

The rush of adrenaline in the body is the peak of the body's excitement, followed by bursts of cold sweat and persistent muscle soreness.

"Saved!"

Director Han told Professor Zhang that the eighty-year-old man's clothes were all wet: "I know ---"

But when it comes to this moment, I don't know how many monstrous waves have been turned in my heart, even if there is an 80% probability, but when it comes to this operation, it is a choice between zero and 100%.

The mysteries of the human body are so complex that no one can guarantee that they will be able to overcome danger every time.

"How's it going?" Dean Chen couldn't stay in the locker room and came out to do activities.

"After passing the ghost gate three times, I almost couldn't get through it just now." Professor Zhang said.

Dean Chen approached the small window on the operating door and looked inside, where the operation was underway.

Extreme tension is followed by uncontrollable relaxation.

The entire observation room was full of doctors, mostly orthopedic and neurosurgeons, all of whom had the feeling of the aftermath of the catastrophe.

But the laser knife did not let up at all, it was still separating, and the separation would go into the deepest part, and the deepest one would now be dug out.

The most dangerous step is coming, and whether the operation can be successful depends on this step.

Even the third time, as long as twenty-one cardiac compressions and defibrillations, is a brush with death.

This time is different, Yang Ping directly has to do surgery when the heart is stopped, that is, he directly does death crossing, and moves forward side by side with the god of death.

"It's incredible, there is no fluorescence imaging, no navigation aids, and the boundaries of the tumor are located so precisely." Johannathan's worshipful mood.

Johanneson felt that the main knife behind the screen was no longer the young doctor, but his mentor.

His wisdom, his courage, his perseverance, his extreme intellectual brilliance in the face of illness.

He is not in a hurry, not dry, not threatened by death, always methodical and meticulously following the scientific plan.

He can come up with a plan to deal with any accident.

Unfortunately, the operation was only allowed to be made public, and if it could be broadcast live in front of doctors around the world, Johanneson would have asked all his colleagues to put down any work they were doing and concentrate on the operation.

What is the limit of human precision, the limit of stability, the limit of rationality---

This surgery is not only the incomparable surgical operation, but also the thorough study of the anatomy, pathology and pathophysiology of the disease before the operation.

"The heart is going to arrest again, everyone remember, don't panic, in addition to drug rescue, any other rescue measures must wait for me to complete the operation before it can be implemented." Yang Ping reminded everyone for the last time.

Because the shock caused by the rescue will affect the operation, and the nerve nucleus damage caused by the operation error will not be rescued in any case.

Yang Ping didn't plan to rest anymore, taking advantage of the current state of being very good, he went all out and took the most difficult step.

While separating, while stopping the bleeding, the laser knife continues to go deeper.

Deep in the tiny medulla oblongata, the laser knife gets deeper and deeper, and the roots of the tree extend in all directions, winding between the nerve nuclei.

Intertwined with the center of life, Yang Ping is ready to dig out this last one.

Eventually, the surgery interfered with the vital center, and the ECG on the screen turned into a frightening ventricular fibrillation wave.

Once the ventricular fibrillation wave becomes a full-hearted arrest, the chance of rescue will be very slim.

For ventricular fibrillation, the sooner the electrical defibrillation, the better, but at this time, the sterile sheet cannot be opened at all, let alone the electrical defibrillation, and even the anesthesiologist is cautious about adrenaline, for fear of interfering with Yang Ping's operation.

Everyone stared at the ventricular fibrillation waves on the screen, their hearts clenched tightly and screwed together.

The operating room was unusually quiet, and Director Ma looked at the ventricular fibrillation waves, worried that it would suddenly turn into a straight line and progress into a full-hearted arrest.

Others kept urging in their hearts: hurry, hurry, hurry.

Dr. Wu's two hands were on the handle of the defibrillator's electrode plate, ready to defibrillate, and the hands of the itinerant nurse had already grasped the tail of the sterile sheet, ready to lift it.

But Yang Ping is still in the operation, and there is no end to it.

Once the golden defibrillation time passes, there is no chance, but I dare not urge, I can only do it in a hurry, and my heart is like fire.

The time on the wall panels, the numerals of the second hand, are constantly increasing, and time is losing little by little.

Yang is as smooth as Mount Tai, the instruments of both hands cooperate, cut, separate, stop bleeding, faster and faster, and the dance of the tip of the knife is going to complete the most difficult scene.

"What's going on?"

In the observation room, everyone couldn't understand what was going on.

Ventricular fibrillation and still operating? Not salvage? Once the best opportunity is lost, no one can save it.

Johanneson muttered, "Completing the operation as quickly as possible while the skipping period is stopped, and the rescue will be carried out after the operation, this is a face-to-face gamble with death." ”

Perhaps, only Johannesen can understand the difficulty, risk and obligation of this last resort.

How much self-confidence and courage is required to do such an operation.

No way, under the current medical conditions, this is an impact on the limit.

Johannathan's adrenaline was so exhausted that he could no longer support his full attention, but he gathered his strength, barely stood up, saluted the main knife behind the screen, and sat back down like mud.

The last straw of life floats on the surface of the water and could sink at any moment.

The laser knife was not affected in the slightest, and the bottom of the tumor was separated as quickly as possible, and finally, it was like digging a sweet potato, and the deepest and last root of the medulla oblongata was successfully dug out.

"Defibrillation!"

A loud and clear command.

Everyone was like an arrow that had been charging for a long time, and they were in place, when the electrode plate of the defibrillator pressed against Feng Lao's back.

One, two, three, four, five, six---

This time, it only took six rounds to successfully electrically cardiovert.

Cardioversion!

Sure enough, a big gamble with the Grim Reaper, the ultimate gamble with no way out, he won.

Successfully complete a death crossing.

As if through a long period of darkness, everyone was exhausted, and finally saw the light of hope, the tumor in the brainstem area was completely removed, and the remaining part of the upper cervical cord appeared very simple.

When the last tumor root isolated, the tumor is like a handful of tree roots, with a trace of blood, thrown into a metal basin.

Under the microscope, the field was clean, and the observation was for five minutes, and there were no bleeding spots, before Yang Ping began to rinse.

"He succeeded?" Griffin was exhausted and hoarse when he spoke.

Woodhead's eyes were blank and he asked, "Succeeded?"

And Johanneson was so excited that he couldn't speak, he didn't hear Griffin's words at all, he looked at the screen with blank eyes, and said to himself: "Success, success, success---"

The whole observation operating room was jubilant, shaking hands with each other and hugging each other.

In the operating room, the work does not stop, irrigation, hemostasis again, cervical skull base fixation, placement and drainage, layered sutures, head and neck incision coverage.

Remove the mount and shift the position to a supine position.

After three hours, a long three hours, the door to the operating room opened.

Professor Zhang, Han Jiangong, Hong Zhigang, and Dean Chen, as well as the doctors who were looking at this side from afar, all gathered here.

"Vital signs are stable, ready to go back to the ICU!"

Yang Ping stood at the door and said.

Director Han hugged him in his arms, his eyes were blurred, and he didn't know what to say.
