At six o'clock the next morning, Fang Han and Solis had already arrived at the hospital again, and there were still two heart surgeries this morning, and the two heart surgeries to be performed today were aortic valve replacement.

"Dr. Solis, Dr. Fang!"

Entering the ward, the patient and his family hurriedly greeted Solis and Fang Han.

The two patients who need surgery are placed in a single ward.

One patient was a middle-aged patient in his forties, and the other was a young patient in his twenties.

Although both patients had aortic valve replacement surgery, the situation was very different.

Today's two aortic valve replacement surgeries, one is a conventional arterial valve replacement, the other is a second operation, the patient has had a heart valve replacement three years ago, but the original mechanical valve has fallen off, this time the operation has to take out the mechanical valve that has fallen off, and then replace it with a metal valve with memory function without stitching.

Comparatively speaking, this secondary valve surgery is the most difficult of the four surgeries this time.

"Dr. Solis, Dr. Fang!"

Zhou Chen's parents stood on the edge of the hospital bed, looking at Solis and Fang Han, their eyes full of anticipation.

Zhou Chen is the patient who needs to have a second valve surgery today.

A second valve replacement surgery is much riskier and more difficult than a first valve surgery.

Removing an artificial mechanical valve that has not completely fallen off or adding a new metal valve is more difficult and risky than the first valve replacement.

In addition, the patient had undergone a heart valve replacement operation three years ago, and the heart function was very poor, and even after the operation, the patient had to take anticoagulant drugs for a long time, and the patient's heart could be said to be full of holes.

In the case of patient Zhou Chen, at present, no similar surgery has been performed in China, and even the big hospitals in Yanjing are a little weak.

"Don't worry, we'll do our best, Dr. Solis is a top expert in the heart, and Dr. Fang is also a first-class expert in our country. Kuang Mingzhuo comforted the patient's family.

"Well, we know, we know. ”

Zhou Chen's parents nodded again and again, their red eyes holding back their red eyes to prevent tears from slipping down.

My son is only twenty-two years old, and he had an operation at the age of nineteen, and he thought he could spend a few years safely, but he didn't expect that it would only be three years, and he would experience another risk, and even this time the risk was much greater than the last time.

"Are you scared?"

Fang Han walked to the edge of the hospital bed and asked while examining Zhou Chen.

"Hmm!"

Zhou Chen nodded, a twenty-two-year-old young man, if he wasn't sick, he would normally be in school and college, and he hadn't entered society, so he was relatively fragile in terms of responsibility and mood.

"Don't be afraid, have confidence in yourself, the stronger the belief, the higher the success rate of the operation, doing the operation is not only our doctor's business, but also your own business, let's work together." Fang Han patted the back of Zhou Chen's hand.

"Well, I will, thank you, Dr. Fang. ”

Zhou Chen looked at Fang Han and said, "Doctor Fang, I've heard of you a long time ago, you're only three or four years older than me, right?"

"I'm more than three years older than you, and I'm five months ahead of my twenty-sixth birthday. Fang Han smiled and nodded.

"Doctor Fang, I will work hard and learn from you. Zhou Chen cheered himself up and said with a smile: "I don't want to have a third operation, or a heart transplant in the future......."

Kuang Mingzhuo on the side also felt that his nose was a little sour, if this operation did not go well, Zhou Chen probably would not have the opportunity to have a third operation.

After encouraging Zhou Chen for a while, Fang Han walked to the front of another hospital bed.

The patient is in his forties and middle-aged, but he is stronger than Zhou Chen.

"Doctor Fang!"

"How do you feel?" Fang Han stepped forward and asked.

"Fortunately, we fully followed the instructions of the hospital and did not dare to be sloppy. ”

"Hmm. Fang Han nodded: "Don't worry, don't worry too much, we will do our best, like the young man next door, you also have to have confidence in yourself, your belief is strong, and the effect is greater than any medicine." ”

"I am very confident that my surgery will definitely be successful. The middle-aged man nodded.

Walking out of the ward, Fang Han and Solis walked towards the operating area, Kuang Mingzhuo followed Fang Han's side, and said in a low voice: "Doctor Fang, will Zhou Chen's surgery be arranged in the first one?"

For today's operation, Zhou Chen is the first, and the middle-aged patient is the second.

It's just that relatively speaking, Zhou Chen's surgery is quite risky, and if the first operation does not go well, it will affect the subsequent surgeries.

"It is precisely because the first operation is difficult and may take a long time, so it will be ....... later."

Fang Han didn't say much, but Kuang Mingzhuo understood.

The operation is complicated, time-consuming, and the physical and energy consumption of the doctor is very large, Fang Han can naturally insist, but Solis, after all, he is in his fifties, if he puts it in the second station, in case Solis is not physically and energetic......

........

At seven o'clock in the morning, the operation began on time.

Because Zhou Chen's condition is complicated, the operation may be difficult and time-consuming, so today's operation was half an hour ahead of schedule, starting at seven o'clock.

"The first surgery to be performed today is the second replacement of the aortic valve, the patient had a mechanical valve replacement three years ago, and now the mechanical valve has fallen off three-quarters.......

At the main venue and the observation room of Jiangzhong Hospital, Lin Xintong and Zhao Manni also introduced the operation to the experts who came at the same time.

"The second valve replacement is much more difficult than the first one. ”

"You have also read the patient's information, the patient's condition is quite poor, this time we should not have many hospitals in China to do this operation, right?"

"I don't know, I don't know if Director Zhang of Xiehe and Director Wang of Yanjing can do it, anyway, our hospital doesn't dare to do it. ”

The experts who came here discussed in a low voice.

In the operating room, Fang Han, Solis and others had already changed into surgical gowns and walked to the operating table.

"Patient, Name"

"Zhou Chen!"

The anesthesiologist performs routine preoperative confirmation.

Fang Han walked over and looked at Zhou Chen, and encouraged: "Don't worry, sleep for a while, it's good to wake up." ”

"Hmm. Zhou Chen nodded.

Fang Han nodded to the anesthesiologist, and the anesthesiologist gave him anesthetic, and Zhou Chen fell asleep in an instant.

Walking onto the operating table, Fang Han still did a routine chest open.

"Electric knife!"

"Gauze!"

Fang Han's voice sounded in the operating room from time to time.

"It's more difficult to open the chest. ”

"yes, it's full of sinuses, and if you touch it a little, it will bleed. ”

The sinus discussed by several doctors refers to the folded part of the arterial vein, a thing that slowly forms after the lesion, and this sinus can bleed if touched slightly.

"Heparin internal neck review meridian administration!"

"Chainsaw!"

In the operating room, Fang Han did it very seriously, and his hands were orderly.

"This Fang Han is really amazing, and today's open-chested work is also quite stable. ”

"Yes, didn't you say yesterday that Fang Han had done heart valve chordae tendinae repair independently, it seems that the level is really not ordinary. ”

"The pericardium is exposed!"

After an hour and ten minutes of thoracotomy, the patient's pericardium was finally exposed.

"The patient's heart is so big!"

"I'll go, it's so big, it's twice the size of a normal person's heart, right?"

"More than twice as much, with such a big heart, the operation is even more difficult. ”

"Fortunately, it's Dr. Solis who is the main surgeon, and this situation has changed us, hehe......"

"Director Wang, what do you think of this operation?"

In the observation room, Zhang Jiahao also discussed with Wang Zhicheng.

"It's hard to say, the patient's condition is not optimistic, the heart condition is poor, and it is a second valve replacement, step by step crisis. ”

Zhang Jiahao nodded.

He was not completely unsure of this operation, but he definitely didn't dare to say how sure he was.

"In addition to the big heart, you see, the inflammatory hyperplasia is also very powerful. ”

"At the root of the aorta, there is bleeding with every step of separation. Wang Zhicheng nodded.

"Ready to build cardiopulmonary bypass!"

"Cool down, left flow strengthened!"

As the pericardium opened and cardiopulmonary bypass was established, Solis began to dignify a lot, ready to remove the mechanical valve that had been replaced earlier.

"Cardiopulmonary bypass has been established, and hopefully it will go smoothly!"

"Yes, cardiopulmonary bypass should generally be controlled within two hours, so as to reduce the damage to the heart as much as possible, if the cardiopulmonary bypass is more than two hours, the damage to the patient's heart and whole body organs is too great, and the patient may not be able to bear it. ”

All the experts analyzed from a relatively professional point of view.

It is inevitable that the shorter the time of cardiopulmonary bypass for cardiac surgery, the less damage to the patient's heart function and organs.

This is also why when Fang Han operated on Long Yaxin last time, he reduced the time of cardiopulmonary bypass as much as possible.

Long Yaxin is recovering so well now, and she looks no different from a normal person, and it is also because of this reason.

"Flap height 4.6!"

Fang Han and Solis were talking in the operating room.

"4.6, if a memory metal flap is placed, a transverse incision should be made at a position of 4.6 cm. ”

Zhang Jiahao and Wang Zhicheng also exchanged in a low voice.

"Well, through this incision, not only will the original artificial mechanical valve be removed, but a new memory metal valve will be placed. ”

“4.6！”

"I'm going, it's going to be so long, it's going to be very troublesome to locate. ”

"It's not just troublesome, it's quite difficult, how to locate such a long distance?"

The doctors discussed, and soon the mechanical valve that had been placed before was also exposed, whether it was the main venue or the observation room of Jiangzhong Hospital, all the doctors could see it clearly through the video.

The engineer in the operating room who debugged the video equipment even gave a close-up.

"I'll go, it's sticking together!"

"How do you take this?"

"It's not easy to take, you can't pull it forcibly, if it causes heart damage, it's troublesome, but the adhesion below is too strong. ”

With the exposure of the surgical field and the close-up on the display screen, all the doctors saw the situation clearly, and the roots of the original mechanical valve that had not fallen off and the semi-annular wall were almost stuck together.......
