Chapter 1791

The operation of moyamoya disease was successfully completed, but Zheng Ren noticed that the ECG monitoring of the experimental body began to fluctuate violently at the moment of leaving, and the heart rate instantly reached 120... 130... 150... 180

Before Zheng Ren did anything, the heart rate of the experimental body fell like a cliff and returned to zero directly.

Without thoracotomy, intrathoracic cardiac compression was performed under direct vision, and the system prompted the subject to death.

Uh

Zheng Ren looked at the experimental body speechless. He was not lost, but he was a little excited.

Although the subject died, the system space told him in this way that he should first go to the outer membrane lung, and then go to the operating room to operate with the machine pushing the outer membrane lung. Alternatively, you can push the patient to the operating room for extracorporeal membrane lung.

Although it is troublesome, it is the only feasible way.

This also explains why the system makes a 50% surgical completion for moyamoya disease bypass surgery.

Just find the reason! Subsequent surgery can be improved.

Zheng Ren starts the next operation immediately.

First, we began to give the experimental lower body adventitia lung.

Extracorporeal membrane lung has two ways of bypass to meet the needs of different conditions.

V-V bypass, venous blood is led out through vein, oxygenated by oxygenator and carbon dioxide is removed, and then pumped into another vein.

This method is suitable for patients with pulmonary failure. V-V bypass is a lung replacement method, which is often used in patients with acceptable heart function and pulmonary failure.

Respiratory department is commonly used for in vitro support of some patients with acute respiratory distress syndrome, acute respiratory failure caused by acute lung injury and other respiratory failure. It mainly uses the membrane lung system of ECMO to provide sufficient oxygenation for patients and strive for time for the recovery of respiratory system function.

V-A bypass, venous blood is led out through vein, oxygenated by oxygenator and carbon dioxide is removed, and then pumped into artery.

This method is the combined replacement of heart and lung. Heart failure and cardiopulmonary failure are commonly used.

If the patient may have cardiac insufficiency or cardiac arrest for a long time, aa-v pathway can be used, that is, two cannulas can be led out from the left and right atrium respectively, and pumped into the artery after oxygenation through oxygenator and carbon dioxide elimination.

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

In case of conscious patients, muscle relaxants such as pancuronium or chlorosuccinylcholine shall be applied before intubation, morphine shall be given intravenously and lidocaine shall be given locally.

However, in the system operating room, the experimental body itself was in general anesthesia, and Zheng Ren saved this step.

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

The intubation selected by Zheng Ren is not very thick. It can provide 2-3l / min flow. Incision, direct vision intubation. The intubation is not deep and tilted at a certain angle to avoid collapse and blood ejection due to high vertical intubation pressure.

After insertion, it shall be confirmed under X-ray. After intubation and suture, the pipeline shall be fixed.

Connecting the machine, Zheng Ren started the operation of moyamoya disease again.

The operation went well. This is the 14th training.

Zeiss's microscope is still very good. Zheng Ren didn't have dizziness and other symptoms like the last surgical training of suturing the intestines.

Operation completion 98%!

Zheng Ren finally breathed a sigh. It should be a success!

But he didn't go back right away. He has spent so much time on surgical training. Why not make the operation perfect?

Another 8 times of operation training were carried out, and the degree of completion increased by 1% to 99%. The operation time was shortened by about 30%, and Zheng Ren was satisfied with the result.

The next step is to persuade the patient's family to have an operation.

If the patient's family members are financially difficult, they can choose to live broadcast the operation.

Zheng Ren decides everything, calmly leaves the system space and returns to the EICU ward.

"Boss Zheng, please consult the whole hospital." Zhao Yunlong suggested, "take a look at neurosurgery. If you feel something wrong, let them make a treatment plan."

"OK." Zheng Ren nodded.

It is also a normal procedure to organize a hospital wide consultation. This is not his own hospital. Zheng Ren can't do whatever he wants like in the system operating room.

In fact, we can't say we do whatever we want. We can reason outside. But big pig hoof never reasoned with Zheng Ren, and the promulgation task was random, not according to the severity of the disease.

Perhaps in the system judgment, the patients in front of us are very difficult to treat, and there may be no need to issue tasks at all.

"Xiao Zhao." Just then, Professor Zhang came in.

"Professor Zhang." Zhao Yunlong replied respectfully.

"The patient's family refused to rob..." Professor Zhang looked at the patient and was stunned when he saw that IABP had gone in.

Is it so fast?

When was Zhao Yunlong so quick in handling affairs? Well, it's usually very agile, but the IABP is too fast.

Professor Zhang then glanced at the ward. When he saw Zheng Ren, he immediately understood what had happened.

"Refuse rescue?" Zheng Ren frowned.

"Yes." Professor Zhang nodded and said, "I communicated with the patient's family. I didn't have much hope and the cost was still great. My family couldn't afford it, so I decided to give up."

He had a good impression of Zheng Ren.

Although Professor Zhang lost face in the last operation on fish bone and mediastinal abscess, that's how medical treatment is. People can do the operation, that's their ability.

Anyone who has points in mind has to admit it.

Professor Zhang has no objection to this.

Young people are young people. It's really hot blood to rescue them. Professor Zhang looked at Zheng Ren, Su Yun and Zhao Yunlong and thought to himself.

When I was young, wasn't it the same? But now it has changed. For myself, this is just a job.

Not to compete with yourself because of a patient who can't be saved.

All the people in the ward were silent.

Professor Zhang felt that the atmosphere was wrong. He said that the patient's family agreed to give up the rescue. Shouldn't everyone be relieved?

Why is the atmosphere so depressing?

"Professor Zhang, that's right." Zheng Ren said: "the patient's situation is quite special, but I think I can rescue it."

"Can you?" Professor Zhang said in surprise.

IABP is on, but the patient's heart rate is not stable. Seeing that the load on the heart is still too large to maintain.

According to experience, the patient will soon have heart failure.

With the technical force of 912, we can do it by hanging our breath and constantly rescuing.

But does it make sense?

Professor Zhang is a little angry.

Young people, in order to show off their skills, take the patient's life as a sacrifice. Is there such a thing to do!

He stared at Zheng Ren and said coldly, "boss Zheng, tell me about the patient."
