Chapter 1027

Li Xinyu looked at the questions that her fiance had specially prepared on the table, and some of them indicated the importance with symbols. She knew that her fiance had deliberately done so, which made her look more professional. She directly glanced at the first key question and read it out as a repeater.

"For this case, which method will Dr. Chen use to collect blood vessels for bypass operation?"

Gu Ning knows that these technical problems are commonplace for a few experts, but they are technical problems for most doctors. If Chen Qun were to explain it himself, I'm afraid most people would be drowsy in less than ten minutes, and the remaining few were just operation maniacs.

The reason why he listed it and let his wife pretend to be an expert is to please others. Besides, he is not afraid of jokes from other doctors. After all, the most powerful volunteer nurse in the hospital is Miss Dongfang, who absolutely supports him to please girls, so he does it in a reasonable way.

"This problem is a specific problem, specific analysis. According to the current image of the patient's coronary artery, all the patients' heart arteries belong to stenotic vessels. According to the characteristics of this blood vessel, Dr. Chen will adopt the simplest and most suitable method, take materials nearby, and directly cut off the internal thoracic arteries on both sides to connect with the right artery. "

"Look at the picture, Dr. Chen has completed the thoracotomy, revealed his heart vision, and started to collect blood vessels. Please pay attention to Dr. Chen's left hand movement, which uses the back of the scalpel to complete the blunt separation of blood vessels, rather than using hemostatic forceps and surgical tweezers. Of course, this can save operation time, but for general doctors, it is not recommended to use the scalpel, because as long as a slight error, it will lead to unpredictable consequences. Well, in our words, Dr. Chen has completed the vascular Union. Maybe for most cardiologists, the speed is incredible, but for Dr. Chen, it's a slow teaching mode. As for Dr. Chen, the fastest speed is to complete the Union in 57 seconds. "

"Wait a minute, Dr. Gu, I don't understand what you mean. You just said Dr. Chen finished the combination in 57 seconds. What's the difficulty and significance of this? For me, it doesn't seem to be very difficult. How many pipes are sewn together? It's like I can do it

"Host, you are wrong here. Many things we seem to be able to do, but we can't do them at all. Just like diving, the same one meter board diving, I can only fall into the water in an irregular ball, but the athlete can turn a somersault in the air, and then drill into the water in a beautiful way. These are all skills, not words. Well, you take the problem far away and go back to the operation in front of you. "

"Well, I just asked if I didn't understand. Now I see Dr. Chen collecting blood vessels. What are the requirements? Please give us an introduction. "

"Look at the blood vessels. Let me enlarge the image. You can pay attention to it through the small picture. The survival rate of myocardial cells will be reduced because the blood flow of anterior wall is blocked due to vascular infarction. In view of this situation, Dr. Chen used LCX of circumflex artery and RCA of left coronary artery for bypass grafting. After the channel was made, the left anterior descending artery was used for bypass grafting. "

"I can understand every word you say, but together, I don't know anything. It looks like a mountain. I see that the introduction here says that the operation needs to cut the necrotic myocardium. How can I judge which myocardium is necrotic? Does it depend on the muscle color? "

"With the progress of science, there are many ways to judge the necrotic myocardium. But at this time, Dr. Chen used the most traditional and simple, in fact, the most difficult method to make a judgment, that is to use the touch of his palm to make and complete the determination. The intact myocardium and the dead myocardium can be felt by touch. "

As soon as Gu Ning's words are finished, he immediately slides the picture on the computer and enlarges the picture of Chen Qun's ongoing actions. It happens that Chen Qun is gently touching the heart wall with a "picky" meat buying technique, and he also gently pinches it from time to time.

Seeing this picture, Li Xinyu can't help holding one of his palms and pinching the muscle on the other arm, as if he didn't notice any difference.

Gu Ning saw that her fiancee, a rational woman, even showed such a child's attitude. He couldn't help laughing and gave her a little explanation.

"Although the requirement of this technique is very low, it actually needs a long period of training for doctors to distinguish the stiffness and weakness of the necrotic part of the myocardium, which is impossible for ordinary people to distinguish in a short time. For our hospital, the most advanced image data comparison has been used to determine the lesion location, while the original method is to determine the lesion part through long-term observation of ultrasonic image. "

Li Xinyu immediately caught the blind spot of this problem.

"Why didn't this demonstration operation adopt the most advanced way of the hospital to determine? Is it easy to demonstrate, or will it take a long time? ""You've asked the right question. The reason why we use the touch of the palm of our hand is that it doesn't need any instruments and it's easy to use. Many operations are carried out in hospitals with incomplete equipment, and some of them are emergency operations, so the external conditions are not so good. Therefore, Dr. Chen used the most traditional methods for demonstration. He also wanted to tell you a simple truth, that is, many traditional methods still have strong vitality in the face of high technology and new technology. We don't need to be eliminated! "

Gu Ning just finished, see Chen Qun suddenly stopped any action, and issued an instruction.

"Check the color Doppler ultrasound and pay attention to the position of the mitral valve. Just now I felt a myocardial necrosis on the mitral valve. This necrosis will inevitably lead to infection of the mitral valve, leading to heart failure and even rupture. Get ready for cardiopulmonary bypass and mitral valve replacement! Give me the scissors and prepare two side cutters! Xiaoxin, do real-time imaging projection immediately! "

Chen Qun's words were not surprised at all. He gave orders in front of countless doctors staring at the live operation. Then a heart the size of a washbasin emerged from Chen Qun's side, as if a huge heart bulge jumped out of the patient's chest, which shocked many people.

"Keep enlarging the left ventricle!"

Chen Qun gave an order to the first lady. Originally, he thought that he didn't need this facility. He deliberately abandoned it. In fact, he didn't want to cause a dispute that "instruments are more important than technology".

But now we suddenly find that the patient's mitral valve has a problem. The most simple and clear demonstration method is to let the eldest lady have a simulation display, and the subsequent real video will also prove that his judgment is correct.

With Miss Dongfang's fingers pounding on the keyboard, she picked up her heart, which expanded to the left ventricle. The two mitral valves, which stretched and stretched to affect the beating of the atrium, were obviously different. One mitral valve seemed to be much thicker than the other, and the long and narrow mitral valve was known to have pathological changes without looking at it, It has shrunk a part, and the fracture will happen sooner or later.

"Blood transfusion tube, drainage vessel, OK, it's connected. Start cardiopulmonary bypass. The reserved vascular access has been completed, and now it's time to start
