Boss, that's awesome. Seeing that Professor Rudolf Wagner was gone, Su Yun came to Zheng Ren's side with a smile, gave a thumbs up, and praised: "You are really skilled in using the method of agitation." ”

"There's no agitation. Zheng Ren said indifferently: "Tell the truth, don't embarrass Fugui'er." What I said before was very simple, and it was no wonder that he was suspicious. ”

"Che, do you think that if you say that, he will have no doubts in his heart?"

"Do your best, what else can I do? Do I want to break in and operate on Dr. Mehar? When I do the surgery, my heart can stop at any time. If you have the opportunity to do it, you should be prepared to defibrillate. Zheng Rendao.

"I am one of the most professional experts in the study of myocardial current, boss, you can rest assured. Su Yun clenched his fist with his right hand and knocked his left chest muscle, which made a bang.

For the specialty of cardiothoracic surgery, Su Yun is still quite confident.

"Knowing that you are an expert, I dare say that the chances of success are high. Zheng Ren was a little tired, slowly closed his eyes, and said as if he was talking in a dream: "I definitely don't trust this face, and I don't believe it either." So if you can't cooperate with the doctor who is circulating with them, once you have cardiac arrest during the operation, it is up to you. ”

"Rest assured. ”

The conversation between the two ends here, what they are talking about is also nonsense and meaningless.

Zheng Ren closed his eyes to recuperate, but Su Yun was chatting with his mobile phone energetically.

There was silence in the observation room. The nursing physician attentively monitored vital signs, and the nurse occasionally went into the room to change Dr. Mehal's intravenous nutrition medication.

A few minutes later, a shrill siren rang out in the room.

Without warning, almost all of the machines roared hoarsely. The doctor in the observation room outside immediately jumped up and rushed into the ward.

The values of all instruments are displayed on a screen in the observation room. Zheng Ren frowned, opened his eyes, and saw that the ECG oscilloscope had turned into a messy waveform.

Sinus rhythm is no longer present, and rapid ventricular fibrillation is shown on the ECG monitor.

Ventricular fibrillation is a rapid and weak contraction of the ventricular muscles or uncoordinated rapid fluttering.

As a result, the heart beats but no blood is pumped out, heart sounds and pulses disappear, blood perfusion stops in organs such as the heart and brain and surrounding tissues, and A-S syndrome attacks, and in the most severe cases, sudden death occurs within a few minutes, or even a minute.

To put it simply, Dr. Mehal's life has come to an end.

Su Yun jumped up as if he had pressed a spring, as if he was in the ICU of Haicheng First Hospital, and wanted to rush in to participate in the rescue.

But in less than a second, he stopped, and a smirk appeared on his handsome face.

"Forget, not at home. Su Yun said.

Zheng Ren didn't speak, staring closely at the busy and orderly rescue behind the transparent glass.

A doctor compresses the heart outside the chest, and the nurse draws the medication and injects it into the patient's intravenous access as quickly as possible.

Another doctor quickly picked up the defibrillator and quickly and evenly applied the conductive paste to the defibrillator.

The upper edge of the STERNVM electrode plate is placed in the second intercostal space on the right side of the sternum, and the upper edge of the APEX electrode plate is placed in the fourth intercostal space of the left midaxillary line.

Everything is carried out very professionally and quickly.

Chest compressions are ineffective, and defibrillation is performed immediately.

Dr. Mehal's body was vaguely shaking, and the waveform displayed on the monitor was still a ventricular fibrillation waveform, without any change.

Zheng Ren forgot that this was the ward of the Carolinska Institute of Medical Surgery in Stockholm, and that the patient being resuscitated inside was Dr. Mehal.

In his opinion, there is only ongoing rescue, trying to save a life.

Compression, medication, and defibrillation have no effect, and all kinds of methods and means commonly used in clinical practice are used.

If you don't get over, the patient dies.

Zheng Ren quickly entered the system space and clicked on the surgical training.

As usual, the test subjects provided by the system are exactly the same as those of the most recent patients.

At this point, the big pig's trotters are still very kind.

Zheng Ren quickly entered the operating room of the system, and picked up the defibrillator according to the operation process.

In the standard position, Zheng Ren pressed the discharge button with both thumbs at the same time to defibrillate.

Exactly as expected, defibrillation failed.

Intravenous β receptor blockers and changing the concentration of various drugs have not been effective.

The subject's heart rate still shows ventricular fibrillation, and after a few minutes, the ECG oscilloscope gradually changes to a straight line.

Subject died.

Zheng Ren frowned and stood in the operating room of the system and began to think.

Countless journals and literature came to mind, and various complex cases provided Zheng Ren with a direction for thinking.

In the subject's case, chest compressions are definitely ineffective.

Zheng Ren's 120 doctors in Haicheng and Yuandian counties said that the rescue method for non-cardiogenic cardiac arrest.

As long as you give a force, you can solve the problem quickly.

The standard time required to prepare before defibrillation is 20 seconds, which can be done without wasting.

However, the subject's condition is that his life force tends to be depleted, and the cardiac biocurrent has weakened to a certain extent, which leads to ventricular fibrillation.

This......

Maybe it's really hopeless.

But Zheng Ren was not reconciled, Dr. Mehal could still have surgery, and he died like this, and he couldn't get over it.

After pondering for a long time, Zheng Ren suddenly had an extremely bold idea in his mind.

Giving up the drug, Zheng Ren increased the direct current of the defibrillator from the standard 200J to 300J. The electrode plate is pressed against the subject, and the thumbs of both hands are pressed to the discharge button at the same time to shock defibrillation.

There was a "bang".

The subject bounces up on the operating table and falls down again. The location of the bilateral electrode plates was a little scorched, but the heart rate only recovered for a moment, and then ventricular fibrillation reappeared.

Not enough, but the direction seems to be right.

Zheng Ren frowned and increased the current of the defibrillator again.

400J！

But this time, the subject's heartbeat stopped directly......

Zheng Ren scolded in his heart, the test subject was electrocuted by himself!

Fortunately, this is a system operating room, and fortunately, I am working with the subject and not the patient.

If you are wrong, you can do it all over again, what a happy thing it is.

Zheng Ren seemed to feel a certain pattern, and his mind began to calculate the relationship between the cardiac biocurrent and the current intensity of the defibrillator.

Several similar articles also surfaced.

After a quick calculation, Zheng Ren adjusted the power of the defibrillator to 330J and then started defibrillation.

With a "bang~", the subject "jumped" on the operating table, and then smashed his body heavily on the operating table.

Zheng Ren immediately looked back at the ECG monitoring.

A new ECG oscilloscope emerges from the left side of the ECG monitor, and the heart rate returns to sinus rhythm.

Although it is in the system space, Zheng Ren sees the waveform of sinus rhythm, which is so beautiful.

That's it!
