v3 Chapter 2461： Non-human surgery

Entering the operating room, Zheng Ren saw that Xie Yiren was tapping the equipment with the mobile nurse. Although Xie Yiren didn't look at himself, he still kept a smiling smile on Yi Ren.

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

Zheng Ren meditated in his heart, luck must be better, then reached out his hand, the lancet patted in the palm of his hand.

Only the trunk of the plum tree was exposed in the surgical field. Zheng Ren chose to open the chest in the middle, slightly away from the location of the scar left by the previous operation, and cut open layer by layer.

Unscrew and remove the wire that fixes the sternum during a surgery.

In the operating room, only the songs of good fortune wafted, and no one spoke. The medical team is like a machine, all communication depends on tacit understanding and eyes.

The chainsaw buzzed and bone fragments and blood dripped on the sterile gauze in Su Yun's hand.

Be careful to protect the thymus, Su Yun suddenly asked, "Boss, continuous valvular disease, did you get a tattoo?"

"It's possible," Zheng Ren said as he explored the pericardium. "Dr. DKSatda of Papworth Hospital, Cambridge, England, reported in 2001 a 28-year-old male patient with a congenital bicuspid aortic valve. He received monthly Tattoo once for 5 years. "

"There are many case reports. This child is fine. Why is a plum tree so big?" Lao He said.

Before he started extracorporeal circulation, he still had time to chat and relax his nervous nerves. Lao He also regrets that Boss Zheng did not receive the Nobel Prize. But he is relatively old and has not participated in the whole process, so his frustration is not very strong.

"For the sake of beauty, you gentlemen won't think about it. For a girl, you think about how big and scary such a scar is on the chest. You can't wear a swimsuit." Su Yundao.

Friends of women can see 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, and he took part of the pericardium and gave it to the Xie Yi people.

"Glutaraldehyde," said the Shea softly.

The equipment nurse poured glutaraldehyde into an empty basin on a sterile table, and soaked the pericardial slice just cut by Zheng Ren.

Zheng Ren looked down at the "familiar" operation area, with some expectations in his heart, hoping that the luck of the operation would be better!

"Ready for extracorporeal circulation!" Zheng Ren said.

Lao He did not ask his assistant to write an anesthesia record sheet, and he went to great lengths for all the operations related to Boss Zheng.

Injected 75 mg of pethidine and 0.3 mg of scopolamine 30 minutes before the operation.

After entering the room, he was given a mask to inhale oxygen, routinely monitor the electrocardiogram and pulse oximetry, and completed a radial puncture catheter to monitor the arterial blood pressure. Induction of anesthesia was given 3 mg of midazolam, 20 mg of etomidate, 10 mg of atracurium cis besylate, and 150 μg of sufentanil.

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

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

Just glanced at the problem, and his vision returned to the operation area again.

Boss Zheng rarely comes to power now, especially rarely calls himself. But every time I shouted that I was on stage, the operation was extremely difficult.

This is trust in oneself. It is not enough to go all out. How dare Laohe go away.

"Prepare for heparinization," Zheng Renshen cried.

As soon as the words came down, Lao He had begun to act. Systemic heparinization followed by extracorporeal circulation.

Extracorporeal circulation was established through cannulation of the ascending aorta and the superior and inferior vena cava, respectively, and the ascending aorta was blocked and attracted through the right superior pulmonary vein.

After the extracorporeal circulation is established, the most important part of the operation is the free aortic valve and the abscess that invades the heart and aortic wall.

The oblique incision was made through the aortic root, and the cardioplegic solution was perfused through the left and right coronary artery openings, and the heart stopped beating satisfactorily.

Zheng Ren fully focused, Zheng Ren reached out, and the hemostatic pliers clapped in his palm.

Exploring the aorta consists of three leaflets, a 15X10mm size vegetation can be seen in the left coronary valve, and an abscess formed at the fibrous junction of the aortic valve and mitral valve under the left coronary valve and without the coronary valve. The mitral valve is free of vegetation.

After 16′23 ″, Zheng Ren asked an outside technician to retrieve the patient's coronary angiography dynamic image.

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

According to the normal surgical procedure, the diseased aortic valve should be removed first. Because it is a second operation, there is abnormal proliferation of local tissue, and there is a huge abscess, and the anatomical structure between square inches is extremely complicated.

Zheng Ren lowered his head, reached out, and lancet patted in the palm of his hand.

Cut it with a knife, 0.62cm from the aortic valve, and then pat the lancet on the patient's leg. The Xie Yi took the smallest mirror pliers in Zheng Ren's hand.

Zheng Ren began to loosen carefully, starting from the root of the aortic mechanical valve, skillfully dissecting the heart tissue, and "picking out" the peripheral and slightly thicker capillaries.

Until then, Su Yun didn't understand what Zheng Ren had just done for coronary angiography.

This method is not non-existent in the previous surgery.

In this way, the blood vessels of the general teacher will harden. Then a skilled anatomy teacher dissected the arteries and veins, and even the capillaries.

Of course, the gross specimens made in this way are not easy, mainly because the skilled anatomy teachers are difficult to find.

I did not expect his boss to show anatomy in front of his eyes and show his skills.

Su Yun is speechless, can normal human blood vessels be compared with blood vessels of a general teacher who is filled with antiseptic solution!

This level of anatomical and surgical techniques is high! This is not all. Su Yun knows that the most difficult thing is to find the capillaries in the actual anatomical location with the contrast agent image of the ephemeral coronary angiography.

The level of watching movies is the same as the level of surgery. They are all non-human, so Su Yun slandered.

"Electric burn, don't let yourself go." Zheng Ren lowered her head, and a capillary was freed under the microscope with pliers. After a pause for one second, he said Shen Sheng before seeing the electric burn.

Su Yun frowned, and his mood was still a little bit confused.

I just saw the image of coronary angiography myself, the black contrast agent flashed off, especially the capillaries at the end, there was only a trace of extremely invisible black, and then disappeared.

The boss knows at a glance? This is incredible.

But thinking about it, Su Yun didn't delay the operation. He threw his thoughts and surprises out of Jiu Xiaoyun and touched the hemostatic forceps in Zheng Ren's hand with electric burn.

A tiny crackling sound came, and a capillary was frozen.
