Chapter 807 Mother's Self-Reproach

The ambulance was already moving very fast.

But for some reason, Ma Yuehui still felt a little slow!

He can't wait for Ferrari to make emergency vehicles!

wrong!

He felt that a new project should be added to the F1 arena, which is the emergency vehicle speed competition.

Seeing that the sweat on Ma Yuehui's head was the same as Yang Xu's self-perspiration, Xu Aiqing took a deep breath and felt that she should persuade the big brother team leader: "Old Ma, I have a suggestion for you."

Ma Yuehui was stunned for a moment, then turned to look at Xu Aiqing: "What advice?"

Xu Aiqing said earnestly: "You're not a young man anymore, pay attention to restraint, it's not like this, I'm not telling you... Whose man is like this at the age of forty? I'll have to talk to my sister-in-law about this someday! "

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

But someone reacted, and the patient lying on the ambulance couldn't hold back and laughed directly: "Hahahaha... oops... oops! Doctor, look, there's blood spurting, I spurting blood!"

The patient who was patronizing and laughing suddenly found that the wound had broken open?

Only then did Ma Yuehui react, and he rolled his eyes at the patient, wanting to say that he deserved 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 in you!"

Qin Fang also nodded: "You can do it with confidence, I don't want my child to..."

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

Perhaps, this could be her last reunion with her child...

And Chen Cang also felt a heavy trust and hope.

This battle must be won!

...

In the operating room, the anesthesiologist Zhou He has already started to prepare.

If he wants to do such an operation, and the child is only 5 years old, he must think carefully!

And here Zhang Yuan and Yang Hui are already sweating on their heads!

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

Zhang Yuan was stunned for a moment, not knowing whether to laugh or cry, he was very tired!

Worse than being nervous!

For the first time, they look forward to the surgery to start soon!

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

Take the scalpel from the nurse's hand.

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

Chen Cang has performed this kind of operation in the special training space, and he is very familiar with it.

This operation is time-limited. Once the time is too long, it will cause myocardial cell necrosis, and even various troubles will follow!

Regular chest solemn incision chest opening!

Then decisively cut off the heart!

There is almost no difference from normal surgery!

The purpose of the operation is actually very simple to describe. 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, you need to sew the door with needle and thread.

Of course, the door can also be replaced directly!

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

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

However, practice has proved that the artificial valve is not ideal enough, and there is a certain potential risk after valve replacement. In recent years, there is an increasing trend for angioplasty.

Mitral valvuloplasty aims to restore the physiological function of the mitral valve and correct the insufficiency caused by valvular disease in a targeted manner.

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

Don't underestimate this valve, it's very expensive! Although it's only a bit bigger... Chen Cang should also consider it for this family who came to Beijing to work.

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

Looking at the constantly moving heart, at this time, Yu Yong just let him choose cryogenic surgery, which can reduce the difficulty of the surgery!

A nurse looked at Chen Cang, stuck the 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 then, it must be abandoned.

Time began to run wild like an hourglass.

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

Zhang Yuan, who was fixing the retractor on the side, was also a little nervous. This was the first time in his life that he had seen someone perform an operation without a heartbeat. He was a little nervous.

The same is true for Yu Yonggang. He has been researching the series of non-stop cardiac surgery over the years, but he is just getting started.

He didn't expect Chen Cang to do it!

For Yu Yonggang, there is some expectation.

Zhou He's eyes were fixed on the patient's vital signs, ready for all kinds of preparations at any time.

No one dares to relax in this operation!

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

There is no time for any hesitation.

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

Mitral valve leaflet chordae tendineae rupture!

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

Chen Cang said directly: "The chordae tendineae of the mitral valve leaflets are ruptured!"

Yu Yonggang was suddenly shocked, the rupture of the tendon chords is not a good thing.

"Should I change the cardiopulmonary bypass machine?" Lao Yu frowned and looked at Chen Cang.

Once the chordae tendineae is ruptured, when repairing, in addition to repairing the damaged valve leaflets, it is also necessary to build an artificial chordae tendineae!

The production process, even under the chest opening, should take about ten minutes at the fastest, right?

Lao Yu is really worried!

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

This Yu Yonggang was stunned for a moment!

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

...

Seeing that Chen Cang was in a hurry, he turned to the nurse and said, "4-0 expanded polytetrafluoroethylene sutures!"

The nurse nodded quickly!

Just after Yu Yong heard it, he stared at Chen Cang, this kid... he wants to make artificial tendine cords while his heart keeps beating!

Correction of mitral regurgitation by replacing the ruptured chordae tendineae with artificial chordae tendineae.

What audacity!

I saw Chen Cang holding a suture needle, and his hand was very steady! Very heavy, but also very coincidental!

The suture needle is equipped with 4-0 expanded polytetrafluoroethylene suture, and the spacer is quickly and accurately sutured to the middle muscle of the genital muscle!

Then suture the edge of the leaflet where the chordae tendineae ruptures, and then adjust the length of the suture and tie it.

This series of operations sounds simple, but the difficulty is much more difficult than imagined!

Yu Yong just turned around and looked at the time!

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

With the beating of his heart, Chen Cang's sutures are getting faster and faster!

The key to the operation is to adjust the length of the artificial chordae tendineae, so that it is neither too long to cause prolapse of the mitral valve leaflets, nor too short to cause limited movement of the valve leaflets!

Therefore, 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 this stitching is scary to think about!

Yu Yonggang looked at Chen Cang's hand speed like a butterfly wearing a flower, like a magician playing poker!

A few nurses on the side looked at Chen Cang's dexterous hands, fast-moving fingers, and steady and powerful arms. For some reason, they blushed!

"Ten minutes left!"

"Nine minutes left!"

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

Yu Yong was stunned for a moment and looked at Chen Cang: "Done?"

Chen Cang nodded and smiled slightly: "Yes!"

Suddenly, everyone was stunned.

Even Zhou He looked at Chen Cang in disbelief. This is... six minutes less than seven minutes, right?

...
