Chapter 623 Wrong, You Can Do It All over Again

"Boss, you're awesome." Seeing Professor Rudolf Wagner leaving, Su Yun came to Zheng Ren's side with a smile, gave a thumbs up, and praised, "You are really proficient in using aggressive methods."

"There is no aggressive method." Zheng Ren said indifferently: "To be honest, don't make things difficult for Fu Guier. What I said before was very simple, so it's no wonder he has doubts."

"Tch, do you think he has no doubts in his heart after you say that?"

"Do your best, what else can I do? Do you want to break in and directly operate on Dr. Mehal? When the operation is performed later, the heart can stop at any time. If you have the opportunity to do it, you must defibrillate Get ready." Zheng Ren said.

"I'm one of the most professional experts in the research of myocardial current. Boss, don't worry." Su Yun clenched his fist with his right hand and knocked on his left chest muscle, making a bang.

Regarding the cardiothoracic surgery specialty, Su Yun is quite confident.

"I know you are an expert, so I dare say that the operation has a high chance of success." Zheng Ren was a little tired, slowly closed his eyes, and said as if he was talking in sleep: "I will definitely not trust you in front of me. I don’t believe it either. So the doctors who circulate with them can’t cooperate, and once a cardiac arrest occurs during the operation, it’s up to you.”

"rest assured."

The conversation between the two ended here, what they were talking about was also nonsense and meaningless.

Zheng Ren closed his eyes and rested his mind, but Su Yun was chatting on his mobile phone in high spirits.

In the observation room, there was silence. The nursing doctor focused on monitoring the vital signs, and the nurse occasionally went into the ward to change the parenteral nutrition for Dr. Mehal.

A few minutes later, a sharp and piercing siren suddenly sounded in the ward.

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

The screen in the observation room has the values ​​of all instruments. Zheng Ren frowned, opened his eyes, and saw that the ECG oscilloscope had become a messy mess.

Sinus rhythm was absent and rapid ventricular fibrillation was shown on the ECG monitor.

Ventricular fibrillation is rapid, feeble contraction or uncoordinated rapid fibrillation of the ventricles.

As a result, the heart beats but no blood is pumped out, the heart sound and pulse disappear, the blood perfusion of the heart, brain and other organs and surrounding tissues stops, and the A-Sydrome attack occurs. Sudden death occurred.

Simply put, Dr. Mechal'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 the first hospital in Haicheng City, wanting to rush in and participate in the rescue.

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

"Forget, not at home." Su Yun said.

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

A doctor presses the heart outside the chest, the nurse draws the medicine, and injects the medicine from the patient's intravenous access as quickly as possible.

Another doctor quickly picked up the defibrillator and spread the conductive paste on the defibrillator quickly and evenly.

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

All operations are extremely professional and swift.

Chest compressions were ineffective, and defibrillation was performed immediately.

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

Zheng Ren forgot that this was the ward of the Karolinska Institute of Medicine and Surgery in Stockholm, and that the patient being rescued inside was Dr. Mehal.

In his view, there is only ongoing rescue, an effort to save a life.

Compression, drugs, and defibrillation all had no effect, and all the methods and methods commonly used in clinical practice were used.

If not, the patient dies.

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

And as usual, the experimental subjects provided by the system had exactly the same symptoms and physical conditions as the recent patients.

In this regard, the big pig's hoof is still very kind.

Zheng Ren quickly entered the operating room of the system, followed the operating procedures, and picked up the defibrillator.

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

Exactly as imagined, defibrillation failed.

Intravenous injection of β-blockers, changing the concentration of various drugs, still has no effect.

The subject's heart rate still showed ventricular fibrillation, and after a few minutes, the electrocardiogram gradually became a straight line.

The subject died.

Zheng Ren stood in the system operating room with a frown, and began to think.

Numerous periodicals and documents emerged in his mind, and various complicated cases provided Zheng Ren with the direction of thinking.

In the case of the experimental subject, chest compressions are definitely ineffective.

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

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

The standard time of 20 seconds to prepare before defibrillation can be wasted.

However, the condition of the experimental subject is that the vitality tends to be exhausted, and the heart bioelectricity has weakened to a certain extent, so it leads to ventricular fibrillation.

this kind of...

Maybe it's really hopeless.

But Zheng Ren was not reconciled. Dr. Mehar could still undergo surgery, so he just died like this, and he couldn't bear it.

After thinking hard, an extremely bold idea suddenly appeared in Zheng Ren's mind.

Giving up the medicine, 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 simultaneously press the discharge button to shock and defibrillate.

There was a "bang".

The experimental subject bounced up on the operating table, then fell down again. The location of the electrode plates on both sides was a bit blackened, 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 heartbeat of the experimental subject stopped directly...

Zheng Ren cursed in his heart, the experimental subject was electrocuted to death by himself!

Fortunately, this is a system operating room, and fortunately, the object of my operation is the experimental body instead of the patient.

Wrong, you can do it all over again, what a happy thing this is.

Zheng Ren seemed to have grasped a certain pattern, and his mind began to calculate the relationship between the heart bioelectricity 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 sound of "bang~", the experimental subject "jumped" on the operating table, and then fell heavily on the operating table.

Zheng Ren immediately looked back at the ECG monitor.

A brand-new ECG oscillogram appeared from the left side of the ECG monitoring, and the heart rate returned to sinus rhythm.

Although it was in the system space, Zheng Ren saw the sinus rhythm waveform, it was so beautiful.

It's done! That's right.
