When he entered the operating room, Zheng Ren saw Xie Yiren and the tour nurse were tapping the equipment. Although Xie Yiren did not look at him, he still left a smiling face at Yiren.

Putting on clothes and gloves on stage, Hu Yanhui put on live glasses again, and the operation officially began.

Zheng Ren silently said in his heart that he must be better luck, so he immediately reached out and slapped the lancet into the palm of his hand.

The plum tree with the pattern was left with only the trunk exposed in the field of surgery. Zheng Ren chose to open his chest in the middle, slightly tilted the position of the scar left by the last operation, and cut it layer by layer.

Unscrew the wire that fixes the sternum for one operation and remove it.

In the operating room, only the songs of good luck were floating, and no one was talking. The medical team was like a machine, and all communication was based on tacit understanding and eyes.

The chainsaw buzzed, and bone debris and blood drips splashed on the sterile gauze in Su Yun's hand.

Carefully protecting the thymus, Su Yun suddenly asked: "Boss, is it caused by continuous valvular diseases?"

"It's possible." Zheng Ren said while exploring the pericardium: "Dr. Satchithananda of Papworth Hospital, Cambridge, UK, reported in 2001 a 28-year-old male patient with a congenital aortic valve. He received a tattoo once a month for a total of five years."

"There are many reports of cases. Why is this child tattooing such a big plum tree on his body?" Lao He said.

Before he started the external circulation, he still had time to chat for a few words to relax his nervous nerves. Lao He also felt a little regretful that Boss Zheng did not win the Nobel Prize. However, he was older and did not participate in the whole process, so he was not very frustrated.

"For the sake of beauty, you, a man, don't think about it. If you change a girl, think about how ugly it is to have such a big scar on the front chest, and you can't even wear a swimsuit." Su Yun said.

Friends of women can look at this issue from a female perspective, and tattoos are quite necessary.

Zheng Ren opened the pericardium and found that there was no adhesion in the pericardial cavity. He left some of the pericardium and handed it to Xie Yiren.

"Glutaraldehyde." Xie Yiren said softly.

The instrument nurse poured glutaraldehyde into an empty bowl on the sterile table and soaked the pericardial slices that Zheng Ren had just cut.

Zheng Ren looked down at the "familiar" surgery area, looking forward to it, hoping that the operation would be better!

"Prepare for extracorporeal circulation!" Zheng Ren said.

Lao He did not ask his assistant to write an anesthesia record sheet. He did his best to have all the operations on Boss Zheng.

30 minutes before the operation, 75 mg of petidine and 0.3 mg of scopolamine were injected into intramuscularly.

After entering the room, a mask was given to inhaled oxygen, and the electrocardiogram and pulse oxygen saturation were routinely monitored, and the radial artery puncture was used to monitor the arterial blood pressure. The blood pressure in the room was 143/74 mmhg. Anesthesia was used to induce imidazolam 3 mg, etomidate 20 mg, atracurium cisphenylsulfonate 10 mg, and sufentanyl 150μg.

After intravenous injection, the tracheal intubation was intubated, mechanical ventilation was performed, the tidal volume was set to 500ml and the breathing frequency was 12 times/min.

Looking at the records on the anesthesia record sheet, Lao He felt impeccable.

Just a glance and eliminated any problems, his vision returned to the art area.

Boss Zheng rarely comes to the stage now, especially rarely calls himself. But whenever he calls himself on stage, the operation is extremely difficult.

This is trust in oneself. It is not enough to do all his strength, so how dare Lao He be distracted?

"Preparinized." Zheng Ren said in a deep voice.

As soon as he finished speaking, Lao He had already started to act. Heparinized the whole body, and then carried out extracorporeal circulation.

Extracorporeal circulation is established through the ascending aorta and the superior and inferior vena cava cannulation, blocking the ascending aorta, and attracting it through the right upper pulmonary vein.

The establishment of extracorporeal circulation is followed by the most important part of the operation - the abscess of the free aortic valve and the dissection that invades the heart and the aortic wall.

The aortic root incision is obliquely incision, and the left and right coronary arteries are scattered and the heart stops and be satisfied.

Zheng Ren was fully focused, and Zheng Ren reached out and slapped the bleeding-stop pliers into the palm of his hand.

The aorta was investigated with three leaflets. A 15x10mm-sized necrota can be seen in the left coronary valve. The left coronary valve has no coronary valve and is formed at the fiber junction of the aortic valve-mitral valve. There is no necrota in the mitral valve.

After 16′23″, Zheng Ren asked the technician outside to call out the dynamic images of the patient's coronary angiography.

Looking up at the image, as shown in the system operating room, he recalled that he had just undergone dozens of hours of surgical training, and all the operations were in the body's memory.

According to the normal surgical procedure, the aortic valve of the lesion should be removed first. Because it is a secondary operation, there are abnormal hyperplasia in local tissues and huge abscesses, and the anatomical structure between square meters is extremely complex.

Zheng Ren lowered his head, stretched out his hand, and slapped the lancet into the palm of his hand.

He cut it with one size fits, 0.62cm away from the aortic valve, and then slapped the lancet on the patient's leg, and Xie Yiren patted the smallest microscopic forceps in Zheng Ren's palm.

Zheng Ren began to wander carefully, and from the root of the aortic mechanical valve, he skillfully dissected the heart tissue, and "selected" all the ends and slightly thicker capillaries.

It was not until this time that Su Yun understood what Zheng Ren was just about to have a coronary angiography.

This method does not exist in previous surgeries.

When making a general specimen, inject anticorrosion fluid from the artery, and then leave a mouth in the vein to allow the excess anticorrosion fluid to flow out.

In this way, the general teacher's blood vessels will become hardened. Then, the skilled anatomy teachers will dissect, arteriovenous, and even capillaries will be vivid.

Of course, it is not easy to make a general specimen like this, mainly because it is difficult to find a skilled anatomy teacher.

Unexpectedly, my boss actually wanted to show off his anatomy and show off his skills in front of him.

Su Yun was speechless. Can normal human blood vessels compare with the blood vessels of the general teacher who is infused with preservative fluid?

This anatomical level and surgical technique are so high that it is so high! This is not all. Su Yun knew that the most difficult thing was to use the instantaneous contrast agent image of coronary angiography to find the capillaries in the actual anatomical position.

The level of watching the movie is the same as the level of surgery, and it is so inhumane, Su Yun murmured in his heart.

"Electric acid, don't get distracted." Zheng Ren lowered his head and used pliers to escape a capillary under the mirror. After pausing for a second, he saw that the electric acid had not yet arrived, so he said in a deep voice.

Su Yun frowned, and he was still a little surprised.

I just saw the image of coronary angiography myself, and the black contrast agent flashed away, especially the capillaries at the ends, which only had a very unseen black appearance, and then disappeared.

The boss will tell at a glance that this is incredible.

But after thinking about it, Su Yun did not delay the operation. He threw away his distracting thoughts and surprises and gently touched the hemostatic forceps in Zheng Ren's hand with electric burn.
