When a doctor opened a plug-in

At this time, the ambulance was already driving quickly.

But I don't know why, Ma Yuehui still feels a little slow!

He wanted Ferrari to build an emergency car!

wrong!

He thinks that there should be a new project on the F1 arena, which is the ambulance speed competition.

Seeing that the sweat on Ma Yuehui's head was like self-perspiration due to yang deficiency, Xu Aiqing took a deep breath and felt that he should persuade the leader of the big brother: "Old Ma, let me give you a suggestion."

Ma Yuehui was taken aback, then turned to look at Xu Aiqing: "What advice?"

Xu Aiqing said earnestly: "You are not a young man anymore. Be careful and behave like this. I didn't say you...Whose man is like this at the age of 40? I have to talk to my sister-in-law about this someday! "

When Ma Yuehui heard this, she was stunned and didn't react for a while.

But someone reacted, and the patient lying in the ambulance couldn't help but smiled directly: "Hahahaha...Ohhhhhhhhh! Doctor, look at it, it's bleeding, I'm bleeding!"

The patient who was patronizing and laughing, suddenly found out that the wound had broken away?

Ma Yuehui also reacted, and cast a blank glance at the patient, wanting to say something worthy of it!

...

...

Chen Cang looked at Qin Fang and his wife and explained all the situation: "This is the situation now, and you have to make a decision!"

Qin Fang's husband looked at Chen Cang and took a deep breath: "Doctor, I believe you!"

Qin Fang also nodded: "You can do it without worry, I don't want my child to..."

Seeing the trusting eyes of the two, Chen Cang nodded and left. The moment he turned around, Qin Fang was already in tears behind him.

Perhaps this may be her last reunion with her child...

And Chen Cang also felt heavy trust and hope.

This battle will be won!

...

In the operating room, anesthesiologist Zhou He has already begun preparations.

If you want to do such an operation, and the child is only 5 years old, he must be considerate!

And here Zhang Yuan and Yang Hui are already sweating!

Chen Cang saw that their hats were wet, and suddenly asked curiously, "Are you nervous?"

Zhang Yuan was taken aback, dumbfounded, he was very tired!

It's worse than nervousness!

For the first time they looked forward to the operation to begin!

The anesthetic gradually took effect, and Chen Cang watched the child's red eyes close, and took a deep breath.

Take the scalpel from the little nurse.

In the affectionate encouragement of the little nurse, Chen Cang clenched tightly.

Chen Cang did not know how many of these operations in the special training space, and he was familiar with it.

This kind of surgery has a time limit. Once it takes too long, it will cause the necrosis of myocardial cells, and even all kinds of troubles will follow!

Regular chest solemn incision to open the chest!

Then cut the happy bag decisively!

There is almost no difference from normal surgery!

The purpose of the operation is actually very simple. The one-way door of the two rooms is damaged. It was originally a whole, and it can work smoothly under the drive of the door shaft.

But now the door is scattered, and even part of the door shaft is not connected.

So at this time, the door needs to be sewn together with needle and thread.

Of course, you can also change this door directly!

However, this is not mitral valvuloplasty, but mitral valve replacement.

As early as the 1960s, after artificial valves were used in clinical practice, angioplasty was almost replaced by valve replacement.

However, practice has proved that artificial valves are not ideal enough, and there is a certain potential risk after valve replacement. In recent years, plastic surgery has increased again.

Mitral valvuloplasty is aimed at restoring the physiological function of the mitral valve, and targeted correction of insufficiency caused by valvular disease.

For this small patient, choosing valvuloplasty is not only low in cost, but in the long run, the effect is more significant!

Do not underestimate this valve, it is very expensive!Although it's only a big fart... For this family working in Beijing, Chen Cang should also consider it.

In fact, sometimes, doctors need to consider many things, not just seeing a doctor!

Looking at the constantly moving heart, at this time, Yu Yonggang asked to choose cryogenic surgery, which can reduce the difficulty of surgery!

A nurse looked at Chen Cang, snapped this watch, and looked at the time: "Doctor Chen? Start?"

Chen Cang took a deep breath: "Start!"

The clock counts down 15 minutes to start!

Even if the operation cannot be completed by that time, you must give up.

Time began to flow like an hourglass.

Chen Cang's eyes were fixed on his heart, and he chose the point of the knife.

And Zhang Yuan, who fixed the retractor on the side, was also a little nervous. This was the first time in his life that he saw someone undergoing beating heart surgery, and he was a little nervous.

The same is true for Yu Yonggang. He has been studying the series of non-stop heart surgery for these years, but he is just getting started now.

He didn't expect Chen Cang to do it!

For Yu Yonggang, there are some expectations.

Zhou He's eyes were fixed on the patient's vital signs, and he was ready at any time.

No one dared to relax in this operation!

After cutting open the heart, Chen Cang decisively explored the mitral valve!

Time does not allow people to hesitate any more.

With the help of the system, Chen Cang quickly found out that he had been prepared by four-dimensional echocardiography and suddenly he underestimated the damage of the mitral valve!

Mitral valve leaflet chordae rupture!

Especially the rupture of the main tendon of the anterior lobe, what should I do?

Chen Cang said directly: "Rupture of the chordae of the mitral valve leaflet!"

Yu Yonggang was shocked, it was not a good thing to rupture the tendons.

"Do you want to change the extracorporeal circulation machine?" Lao Yu frowned and looked at Chen Cang.

Once a chordal rupture occurs, when repairing, in addition to repairing the broken valve leaflet, an artificial chordal must be established!

It takes about ten minutes at the fastest to make this process even with the chest open.

Lao Yu is really worried!

And Chen Cang shook his head faintly, and said, "No need."

This stunned Yu Yonggang!

At this time, if Tao Mi and others were on the scene, they would definitely say, "Hey! Look! Look, Xiao Chen is about to start acting!"

...

I saw Chen Cang not hurried, turned to the nurse and said, "4-0 expanded polytetrafluoroethylene suture!"

The nurse nodded quickly!

After Yu Yong just heard it, he stared at Chen Cang, this kid...who needs to perform artificial chords while the heart is beating!

Correction of mitral valve insufficiency by replacing broken tendons with artificial chordae.

So courageous!

I saw Chen Cang holding the suture needle, his hand very steady!It's heavy, and it's a coincidence!

The suture needle is equipped with a 4-0 expanded PTFE suture, which can quickly and accurately sew the gasket on the middle muscle of the musculus muscle!

Then sew on the edge of the valve leaflet at the rupture of the chordae, and then adjust the length of the suture to tie.

This series of operations is simple to say, but the difficulty is much harder than imagined!

Yu Yong just turned around to see the time!

And the nurse kept reminding the time: "There are still 12 minutes...and..."

With the beating of his heart, Chen Cang's stitching is getting faster and faster!

The key to the operation is to adjust the length of the artificial chords so that they are neither too long to cause prolapse of the mitral valve leaflets, nor too short to cause restricted movement of the leaflets!

So the difficulty of the operation is far higher than expected, and... the most important thing is that the heart is still beating at this time!

The difficulty of stitching makes it terrible to think about it!

Yu Yonggang watched Chen Cang's hand speed like wearing a butterfly, like a magician playing cards!

And the few nurses on the side looked at Chen Cang's dexterous hands, fast-moving fingers, steady and strong arms, some blushing for some reason!

"There are still 10 minutes!"

"There are nine minutes left!"

At this moment, Chen Cang breathed a sigh of relief: "Change the line!"

Yu Yonggang was taken aback and looked at Chen Cang: "Done?"

Chen Cang nodded and smiled slightly: "Yes!"

Suddenly, everyone was stunned.

Even Zhou He looked at Chen Cang incomprehensibly, this is only... six minutes less than seven minutes, right?

...
