The operation for smoke disease was successfully completed, but Zheng Ren noticed that the ECG monitoring of the experimental subject began to fluctuate violently, and his heart rate instantly reached 120…130…150…180…

Before Zheng Ren could do anything, the heart rate of the experiment fell like a cliff and went directly to zero.

Without opening the chest, he performed heart compression in the chest under direct vision, and the system prompted the experiment subject to death.

Well……

Zheng Ren looked at the experimental subject speechlessly, without any loss, but a little excited.

Although the experiment subject died, the system space used this method to tell him that he should first go to the outer membrane lung, and then go to the operating room for surgery on the machine pushing the outer membrane lung. Or, the patient can be pushed to the operating room for the outer membrane lung.

Although it's troublesome, this is the only way to do it.

This also explains why the system performs 50% surgery for bypass surgery for smoke disease.

Just find the reason! It’s enough to make improvements in subsequent surgery.

Zheng Ren immediately started the next surgery.

First, start giving the outer membrane lungs under the experiment.

There are two ways of transfusion in the extracorporeal membrane lungs to adapt to different needs of the disease.

V-v transfer, venous blood is drawn out through the vein and oxygenated through the oxygenator and carbon dioxide is eliminated before being pumped into another vein.

This method is suitable for patients with lung failure. The v-v transfer method is a lung replacement method and is often used in patients with cardiac function but lung failure.

Respiratory departments are more commonly used and can be used for in vitro support for patients with acute respiratory distress syndrome, acute respiratory failure caused by acute lung injury and some other respiratory failure patients. It mainly uses the ecmo membranous lung system to provide patients with sufficient oxygenation and gain time for the recovery of respiratory system function.

V-a transfer, venous blood is drawn out through the vein and oxygenated through the oxygenator and carbon dioxide is eliminated before being pumped into the artery.

This method is a replacement method of heart and lung combination, which is commonly used for heart failure and heart and lung failure.

If the patient may experience long-term cardiac pumping insufficiency or the heart stops beating, the aa-v pathway can be used, that is, two cannulations are introduced from the left and right atria respectively, and oxygenated through an oxygenator and carbon dioxide is eliminated before being pumped into the artery.

This method can not only ensure sufficient blood flow assisted support, but also prevent cardiopulmonary thrombosis and prevent pulmonary edema.

If you are awake, before intubation, use muscle relaxants such as pancuronium bromide or chlorosuccincholine, and give morphine intravenously and locally lidocaine.

However, in the system operating room, the experimental subject itself was in a state of general anesthesia, so Zheng Ren saved this step.

After 100u/kg of heparin was given, cervical arteriovenous cannulation was performed.

The intubation chosen by Zheng Ren is not very thick, and it can provide a flow rate of 2-3l/min. Incise and look directly at the intubation. The intubation is not deep and tilts at a certain angle to avoid disintegration and blood spraying when the pressure of the vertical intubation is too high.

After insertion, confirm under the x-ray, and after the intubation cannula is sutured, then fix the pipe.

Connecting the machine, Zheng Ren started to have another operation for smoke disease.

The operation went smoothly, this was the 14th training session.

Zeiss' microscope is still very good. Zheng Ren did not experience dizziness and other symptoms like the last surgical training of suturing the intestine.

The surgery is 98% complete!

Zheng Ren finally let out a long sigh, it must be done!

But he didn't go back immediately. He had spent so much time in surgery. Why not make the surgery perfect?

Eight more surgical training sessions were conducted, and the completion rate increased by 1% to 99%. The operation time was shortened by about 30%, and Zheng Ren was quite satisfied with this result.

The next step is to convince the patient's family to perform the operation.

If the patient's family is in financial difficulties, they can choose to perform live surgery.

Zheng Ren calculated everything, calmly left the system space, and returned to the eicu ward.

"Boss Zheng, please ask for a consultation in the whole hospital." Zhao Yunlong suggested on the side, "Look at the neurosurgery department. If you feel there is a problem, let them make a treatment plan."

"Okay." Zheng Ren nodded.

Organizing a hospital-wide consultation is also a normal procedure. This is not a hospital run by oneself, and Zheng Ren cannot do whatever he wants like in the system operating room.

In fact, it cannot be said that he is doing whatever he wants and can reason outside. However, the big pig's hoof never reasoned with Zheng Ren, and the task is random, rather than based on the severity of the disease.

Perhaps in the systematic judgment, the patient in front of him is the kind of extremely difficult to treat, and it may not be necessary to issue a task at all.

"Xiao Zhao." As he was speaking, Professor Zhang walked in.

"Professor Zhang." Zhao Yunlong replied respectfully.

"The patient's family refused to rob..." Professor Zhang looked at the patient and saw that Iabp had already gone in, so he was stunned for a moment.

Is it so fast?

When did Zhao Yunlong do things so quickly? Well, he is also very quick in normal times, but this IABP is too fast.

Professor Zhang then looked at the ward. When he saw Zheng Ren, he immediately understood what was going on.

"Refusing to rescue?" Zheng Ren frowned.

"Yes." Professor Zhang nodded and said, "I communicated with the patient's family. I had little hope and the cost was still very high. The family was unable to bear it, so I decided to give up."

He had a pretty good impression of Zheng Ren.

Although Professor Zhang was more or less embarrassed when he had a fish bone or mediastinal abscess surgery, this is how the medical treatment is. If someone can do the surgery, that is, that's the ability.

Anyone who knows something in his heart must admit this.

Professor Zhang has no objection to this.

Young people are young people, and it is really passionate to rescue them. Professor Zhang looked at Zheng Ren, Su Yun and Zhao Yunlong and thought to himself.

Isn’t it the same when I was young? It has changed so far. For me, this is just a job.

You won’t compete with yourself because of a patient who cannot be rescued.

Everyone in the ward was silent at the same time.

Professor Zhang felt that the atmosphere was wrong and said that the patient's family agreed to give up the rescue. Shouldn't everyone breathe a sigh of relief?

Why is the atmosphere so depressing?

"Professor Zhang, that's right." Zheng Ren said: "The patient's condition is quite special, but I think I can still save it."

"Also?" Professor Zhang said in surprise.

Iabp has been on all, but the patient's heart rate is still unstable, and the heart is still too heavy and it is difficult to maintain.

Judging from experience, the patient will soon suffer from heart failure.

With the technical strength of 912, I breathed a sigh of relief and continued to rescue, and I could do this.

But does it make sense to do this?

Professor Zhang was a little angry.

In order to show off one's skills, young people use the lives of patients as sacrifices. Is there such a thing for them?
