The system takes me for surgery

Both Shen Weiwei and Cao Chong thought they heard it wrong, and they couldn't believe the gaze they cast on Lu Chenhao.

She remembered that she felt weird at first, and thought that the operation would be too difficult for her, so Lu Chenhao asked Liang Yi to come over to be his assistant, but found something wrong!

not……

Shen Weiwei asked: "Do you want Liang Yi to perform this operation?"

Zhang Jiayue also thought she heard it wrong, and asked, "Director."

Lu Chenhao was obviously right. He smiled slightly, with the corners of his mouth raised, and said, "If I didn't let him come back to be the chief surgeon, then why would I let him come here?"

Such a dangerous and difficult operation was actually handed over to Gui Peisheng. It is said that he is a lunatic, but he is not so crazy!
Shen Weiwei and Cao Chong looked at each other in disbelief.

The anesthetist Lao Hong just wanted to say something.

Lu Chenhao said to everyone in the operating room: "Let's start, we are here for surgery, not for a meeting. The meeting should be held outside."

Zhang Jiayue knew that her director didn't want to explain too much, and didn't dare to ask any more, so she hurriedly disinfected the towels.

Director Shen Weiwei also followed, and she asked, "Director Lu said we have to stay here."

Lu Chenhao nodded and said, "Yes, of course it's best for you to be here, and now you have to go out and have trouble with their families for a long time, so it's better to stay here."

What he said was the truth. If he went out now, he would definitely run into Lin Yiyi's husband and explain to him a lot of the situation in the operating room. Rather than getting along with such angry family members, it would be better to stay in the operation room The patient is guarded in the room, so that the patient has an extra layer of security.

Liang Yi put on new gloves. To be honest, he felt a little uneasy at this time. He had read a lot of aortic dissection surgery cases, and sometimes encountered such a condition as aortic dissection rupture. Powerless.

Of course, this is a kind of pressure. On the other hand, it can be seen from her husband's state that he doesn't trust them doctors very much. If there is any problem, the consequences will be disastrous.

Acute type A dissection, regardless of the presence or absence of aortic insufficiency, should be treated with emergency surgery.

Chronic type A dissection combined with aortic insufficiency has indications for surgery regardless of the diameter of the tumor, and surgery must be performed as soon as possible.

For patients with acute type A dissection combined with cerebral insufficiency, it is not a contraindication for surgery, but an indication for emergency surgery.

In the above three situations, the general conclusion is that type A dissection should be operated on as soon as possible. Thinking of this, Liang Yi kept the family factor in his heart, because this is an emergency operation that must be done.

Lin Yiyi, who is currently under general anesthesia, can't see her child for the first time like other mothers. In Liang Yi's view, Lin Yiyi is a great mother, and the process of her pregnancy is really difficult.

The most common and important symptom of acute thoracic aortic dissection is sudden severe pain like tearing. The patient will have a severe feeling of dying. Liang Yi can imagine how painful she was in the operating room.

Lu Chenhao watched from the side as the second assistant. In non-emergency situations, he took a wait-and-see attitude. Zhang Jiayue was Liang Yi's assistant.

Shen Weiwei watched from the side, glanced at Cao Chong, and muttered, "Does he even intend to go on stage?"

Cao Chong whispered: "With his state and position, it seems that he wants to be a hands-off shopkeeper."

Liang Yi read Lin Yiyi's image inspection report again, closed his eyes, paused for ten seconds, opened his eyes, collected himself, held a lancet, under the shadowless lamp, the blade was covered like a layer of frost, and looked extraordinarily cold .

He chose to make an incision in the middle of the sternum, and in consideration of arch replacement, he extended the incision to the left supraclavicular fossa appropriately.

Liang Yi raised his head and said, "Prepare for arterial cannulation."

The equipment nurse gave it to Zhang Jiayue.

Considering Lin Yiyi's femoral artery pulsation was poor, and considering femoral artery dissection, Liang Yi chose to intubate the right subclavian artery.

Liang Yi said: "Turn on the body circulation and adjust to the deep low temperature mode."

The human heart is full of flowing blood. In heart surgery, extracorporeal circulation technology can replace the patient's own cardiopulmonary function. It not only ensures that the heart is emptied of blood, stops beating, facilitates surgery, but also ensures the normal operation of other organs in the body.But at normal body temperature, if an organ is deprived of a blood supply, damage or death will occur rapidly.

Scientific research shows that low temperature will reduce human metabolism, that is to say, cooling can prolong the time for organs to tolerate ischemia, slow down metabolism, and ensure the survival of tissues and organ functions.

The extracorporeal circulation machine draws the blood out of Lin Yiyi's body, uses a thermostat to cool down the blood, and then reinfuses the blood back into the body to cool down the temperature of various parts. After slow cooling, Lin Yiyi's body temperature is reduced to about 15 degrees. In addition to the selective brain perfusion and continuous blood supply to the brain, the blood circulation in all parts of the body is completely stopped. Since the low temperature only prolongs the ischemic tolerance time of the organs, it will cause hypoxia throughout the body if it exceeds a certain period of time. The best time to stop the circulation The shorter the better.

So they have to shorten the operation time as much as possible, and now they need to infuse the first dose of cardioplegia into it.

Generally, the ascending aortic dissection is incised and perfused directly through the opening of the left and right coronary arteries, followed by continuous reverse perfusion through the coronary sinus.

When Zhang Jiayue was just doing the perfusion, Lu Chenhao vaguely noticed that something was wrong, and Liang Yi shouted decisively: "Immediately change the perfusion method, and adopt intermittent perfusion through the opening of the left and right coronary arteries."

Lu Chenhao gave him an appreciative look and said, "You're fine, you're sharper than me. It seems like you're a sensitive little daughter-in-law. She has an accurate sixth sense."

Why did the words that should have been praised sound so awkward in his mouth?

Liang Yi could only smile helplessly and said, "Thank you, I am sensitive by nature, and the size is just like this."

Shen Weiwei and Cao Chong saw that Liang Yi's reaction speed was faster than that of the chief thoracic surgery director. At first, they doubted whether Liang Yi could be competent, but now they felt that their worries seemed a little unnecessary.

Cao Chong said, "Liang Yi is very stable."

Shen Weiwei said: "Look more, although it is not scientific, but the surgical operation is not divided, his rhythm is very good, study hard, I am also learning."

Cao Chong had never heard of the director having such a high opinion of a young doctor.

"Student Zhang, this infusion is very particular." Lu Chenhao watched from the side. He trusted Liang Yi's technique, so he didn't pay too much attention to his specific operation, but explained the key points to Zhang Jiayue.
