Chapter 596

Teacher Meng's words directly made these "Chencang backup group" dumbfounded!

Director Tao closed his eyes and said nothing. Xia Gaofeng looked even worse. I don't know. Ask him.

Cui Yuanwu looked at Meng Xi: "director Meng, don't lie to us. Director Tao gave us all the explanations. Xiao Chen is saving his strength and breaking out at the critical time, right?"

Speaking of this, Cui Yuanwu lowered his voice, smiled and said, "it's all right. We're very strict!"

Meng Xi rolled his eyes when he saw this!

How can these people be blindly confident in Chen Cang!

Meng Xi just turned around and saw that Cui Yuanwu and his teacher Yang Jianshu had opened.

Meng Xi couldn't help sighing.

……

……

As soon as Chen canggang came in, the two examiners were stunned because they had seen Chen Cang yesterday!

Chen Cang just used the repair of ascending aorta injury yesterday. The two examiners discussed that they couldn't sleep all night. Unexpectedly, they met Chen Cang again today!

The two examiners were surprised and delighted!

Even... There is a little expectation in my heart.

However, the two of them can't be too obvious under the surveillance camera.

Examiner sun is happy to look at Chen Cang. He is a little happy in his heart, but he still said faintly: "please note that at this time, another operation is being carried out in the operating room of the emergency center. There is not enough centrifugal pump to use. Please use the available instruments to start your operation!"

After listening, Chen Cang nodded.

"Are the candidates ready?"

Chen Cang: "ready!"

"Start now!"

As soon as the voice fell, the voice of ECG monitor began to ring, and the descending aorta continued to flow out of blood!

Chen Cang was dumbfounded when he saw the wound!

This... This wound is completely different from what I met yesterday

The difficulty of operation has been greatly improved.

Although they are the same descending aorta repair, the repair methods need to be used are different due to different injury sites and wound sizes.

Today's operation is obviously no longer a simple vascular repair and suture, and the difficulty is greatly improved!

Chen Cang stared at the bleeding point of the wound and did not stop bleeding rashly, let alone directly use hemostatic forceps!

Keep thinking about all these surgical methods in your mind!

The wound has a large crack and multiple injuries. The direct blocking blood flow suture method is only applicable to the wound with small crack in case of emergency. It can be repaired directly, but the time is strictly controlled!

Similarly, it is also required to clamp the aorta to suture the fissure. The time for the aorta to receive occlusion is very limited!

Chen Cang's suture speed is very fast, but it can't. this is not an optimal choice.

Sometimes, the method you choose must have fault tolerance, which is the best choice for surgery!

This is not to say that this risky rapid suture is not good. It can only be said that when there are no other surgical methods available, this is the only choice.

We should know that doctors are human and have the chance to make mistakes, not machines. People will be very random.

After several seconds of consideration, Chen Cang made a choice in an instant!

At this moment, in this state, it is the best choice to use centrifugal pump for partial flow!

There is no need for heparinization, just need to bypass from the left atrium or left upper pulmonary vein to the descending aorta at the distal end of the tear according to the patient's condition.

Unfortunately, there is no centrifugal pump for Chen Cang to use!

This tests a doctor's adaptability!

Chen Cang thought a little, turned around without hesitation and said to the nurse:

"Hemostatic forceps!"

The nurse immediately handed it over.

Sun happily looked at Chen Cang's operation and frowned slightly. What should Chen Cang do?

Deputy examiner Hou Liang also pondered. Should he challenge his limits, give full play to his advantages of rapid suture, and directly choose rapid suture when clamping blood vessels with hemostatic forceps?

In this way, even if they succeed, they may not give the highest score, because Chen Cang did not use the optimization principle in the selection of surgery.

After stopping bleeding, Chen Cang said to the nurse, "shunt heparin treatment!"

As soon as the words came out, the two examiners were relieved and nodded happily.

He didn't take risks!

Choose Gott shunt method!

After the operation, Chen Cang cut the open heart package directly in front of the left phrenic nerve to expose the ascending aorta from the pericardium!

Carefully separate the ascending aorta and descending arch, free and block the distal and proximal thoracic aorta and the proximal left subclavian artery.

Although the Sims are not very similar to humans, Chen Cang still pretends to be nervous and avoids them carefully

Well, although it's a simulant, you should also pretend to look like a real person.

Chen Cang thinks he is Chen Yingdi now!

Chen Cang inserted the proximal lumen of the plastic tube into the ascending aorta and the distal end into the distal end of the descending aorta, and then sewed the 3-0 non-invasive suture with two layers of purse strings, tightening carefully!

After removing the accumulated gas in the pipeline, open the intubation and circulation!

In this way, the wound site is just separated, and the operation can naturally have enough time to repair the descending aorta!

But!

Gott shunt method has a fatal disadvantage!

That is, the flow can not be controlled.

What do you mean?

Once the bypass is opened, there is enough blood flow in the pipeline, which is not conducive to the operation, but even coagulation!

Even if the blood flow is too fast, there will be some negative effects.

Chen Cang's previous operation was very accurate, just like the textbook Gott shunt operation.

However, the examiners sun happy and Hou Liang looked at Chen Cang with great interest, because the next thing waiting for Chen Cang is not just a difficult operation!

Even an accident!

you 're right!

Do you think the Sims won't have an accident?

These are all program settings, okay

After all, human surgery also has accidents, and this kind of high price simulation human accident can be simulated.

Sure enough!

When Chen Cang was preparing to suture, the operation immediately encountered an accident. The patient had problems with bypass flow because his blood pressure was very low!

Even... Caused reflux!

Sun looked at Chen Cang with great interest and wanted to see how he handled it.

But

Chen Cang was unmoved, gently adjusted the shunt tube to an angle, and suddenly a one-way valve appeared!

All of a sudden, the two examiners were stupid!

When will the boy put a one-way valve in the shunt pipe!

Did he already guess?

Sun Xiaoxing keenly realized that Chen Cang did not guess, but designed it according to the patient's blood pressure.

This is the basic professional quality that a good surgeon should have.

This is a high degree of grasp and control of the operation!

Be prepared for any accident.

However, at this time, Chen Cang said to the nurse, "give me two silk threads!"

Sun Xiaoxin and Hou Liang looked at each other. What were they doing with the silk thread?
