Chapter 597 Perfect!

Teacher Meng's words made this group of "Chen Cang Support Team" dumbfounded!

Director Tao closed his eyes and didn't say a word, Xia Gaofeng even looked like I don't know, you ask him.

And Cui Yuanwu looked at Meng Xi: "Director Meng, don't lie to us, Director Tao explained everything to us, Xiao Chen is preserving his strength and breaking out at a critical time, right?"

Having said this, Cui Yuanwu lowered his voice and said with a smile, "It's okay, we are very strict!"

Seeing this, Meng Xi rolled his eyes!

How could these people have blind confidence in Chen Cang!

As soon as Meng Xi turned around, he saw that Cui Yuanwu and teacher Yang Jianshu had already opened the market.

Meng Xi couldn't help sighing.

...

...

As soon as Chen Cang came in, the two examiners were stunned for a moment, because they had met Chen Cang yesterday!

Just yesterday, Chen Cang used the ascending aorta injury repair surgery to make the two examiners talk about being unable to sleep for one night. I didn't expect to meet Chen Cang again today!

The two examiners were both surprised and delighted!

There is even a little hope in my heart.

However, under the surveillance cameras, the two of them could not be too obvious.

The chief examiner, Sun Xingxing, looked at Chen Cang, feeling a little happy, but he still said lightly: "Please note, candidates, at this time, another operation is going on in the operating room of the emergency center, and there is not enough centrifugal pump to use, please use the available centrifugal pump. instrument to start your operation!"

After Chen Cang heard this, he immediately nodded.

"Are students ready?"

Chen Cang: "Ready!"

"Start now!"

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

After Chen Cang saw the wound, he was dumbfounded!

This... This wound is completely different from the one I encountered yesterday...

The difficulty of surgery has been greatly increased.

Although they are both descending aortic repairs, the repair methods that need to be used are different depending on the site of injury and the size of the wound.

Today's surgery is obviously no longer as simple as simple blood vessel repair and suture, and the difficulty is greatly improved!

Chen Cang stared at the bleeding point of the wound, but he did not stop the bleeding rashly, nor did he directly use the hemostatic forceps!

I keep thinking about all these surgical methods in my mind!

The laceration of the wound is large and there are multiple injuries, and the direct blocking of blood flow suture method is only suitable for wounds with small lacerations in an emergency. It can be repaired directly, but the time is strictly controlled!

In the same way, clamping the aorta to suture the tear also has this requirement, and the time for the aorta to receive the blockage is very limited!

Chen Cang's stitching speed is very fast, but no, this is not an optimal choice.

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

Not that this risky quick suture isn't good, it's just that it's the only option when no other surgical options are available.

You must know that doctors are human beings and have the chance to make mistakes, not machines. Humans have a lot of randomness.

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 a centrifugal pump for partial flow!

Heparinization is not required, and only a diversion from the left atrium or left superior pulmonary vein to the descending aorta distal to the tear is required according to the patient's condition.

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

This is a test of a doctor's adaptability!

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

"Hemostatic forceps!"

The nurse immediately handed it over.

Sun Xingxing looked at Chen Cang's operation and frowned slightly, what exactly is Chen Cang going to do?

Deputy examiner Hou Liang also pondered, should he challenge his own limits, give full play to his advantages of quick suture, and directly choose to fast suture the blood vessel with hemostatic forceps clamped?

In this way, even if they are successful, the two will not necessarily give the highest score, because Chen Cang did not use the optimization principle in terms of surgical selection.

After Chen Cang stopped the bleeding, he said to the nurse, "Shunt tube for heparin treatment!"

As soon as these words came out, the two examiners breathed a sigh of relief and nodded in relief.

He didn't take risks!

Use Gott's shunt method!

After the operation, Chen Cang cut the pericardium directly in front of the left phrenic nerve and exposed the ascending aorta from the pericardium!

The ascending aorta and descending arch were carefully separated, and the distal and proximal thoracic aorta and the proximal left subclavian artery were freed and blocked.

Although sims and humans are not very similar, but... Chen Cang still pretended to be neurotic and carefully avoided...

Well, even though it is a simulation, but also pretend to look like a real person.

Chen Cang felt that he was now the film emperor Chen!

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

After removing the air in the tube, open the cannula and flow!

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

but!

Gott shunting method has a fatal disadvantage!

That is, the flow of traffic cannot be controlled.

What does that mean?

Once the bypass is opened, there is enough blood flow through the pipeline, which is not only unfavorable for the operation, but even causes blood coagulation!

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

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

However, the chief examiners, Sun Xingxin and Hou Liang, looked at Chen Cang with great interest, because what awaited Chen Cang next was not just a difficult operation!

There was even an accident!

That's right!

Do you think sims will have no accidents?

These are all programmed or not...

After all, human surgery is also accidental, and the accident of this kind of high-priced simulant can be simulated.

really!

Just when Chen Cang was about to be sutured, the operation immediately encountered an accident. Because the patient's blood pressure was already very low, there was a problem with the diversion flow!

Even...caused reflux!

Sun Xingxing looked at Chen Cang with interest and wanted to see how he would deal with it.

But……

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

All of a sudden, the two examiners were dumbfounded!

When did this kid put a one-way valve in the shunt!

Did he already guess it?

Sun Xingxing was keenly aware that Chen Cang did not guess, but designed it himself based on the patient's blood pressure.

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

This is a high degree of grasp and control of surgery!

Be prepared for any accident.

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

Sun Xingxing and Hou Liang looked at each other, what were they doing with the silk thread?
