Chapter 412 Let Me Try

Remember [new] in one second! "What?! He started operating again?"

Wan Jingshui turned around and looked at operating room No. 3.

Sure enough, Lu Chen moved again!

The chief surgeon also came back and brought in the cardiac ultrasound machine.

When Wan Jingshui saw the cardiac ultrasound machine, his heart suddenly shook, "Is this going to..."

Everyone who saw the change here did not leave and sat back down one after another.

From beginning to end, there was only one person who remained motionless, and that was Yao Jie.

She stared closely at Senior Brother Lu Chen on the screen, with uncontrollable joy in her eyes.

…

Cath lab, operating room three.

"Classmate, are you sure you want to do this?" The surgeon in charge looked at Lu Chen with an extremely solemn expression on his face.

"Yes." Lu Chen nodded, "I did this not only because of my assessment, but also because of this patient. If this patient is not solved at once, he will have to undergo puncture, intubation and anesthesia next time. Why bother? What about this second sin?”

The surgeon was unsure and said, "Let's do this. You use cardiac ultrasound to locate it first. I have already contacted Professor Qin and he will be here soon."

"Okay." Lu Chen nodded slightly, then took the heart ultrasound probe and positioned it on the patient.

Why use cardiac ultrasound?

Because Lu Chen thought of a feasible solution, which is to perform ablation from the opposite side of the endocardium, that is, on the epicardium side, so as to achieve the effect of "internal and external attack".

However, this plan requires the insertion of a catheter to the outside of the heart after pericardial puncture, which is extremely difficult and risky.

This is the only solution Lu Chen can think of at the moment.

With usual pericardiocentesis, patients generally have moderate to large pericardial effusion.

Although there are certain risks, as long as the positioning is correct, the needle is inserted into the pericardium and the fluid is drained.

With the current puncture, the patient does not have any pericardial effusion. After the needle penetrates the pericardium, it can easily damage the myocardial tissue.

The difficulty and risk are several times higher than those with pericardial effusion!

And there is another point. Is Lu Chen capable and qualified to perform this kind of puncture surgery?

So much so that the surgeon in charge needs to contact Professor Qin Sifeng, the examiner this time, in order to make the next diagnosis and treatment plan.

…

Soon, Lu Chen performed a cardiac ultrasound on the body surface, and Qin Sifeng also rushed to the catheterization room.

"What's going on? You're calling me here in such a hurry?" Qin Sifeng walked at the front of the crowd with his hands behind his back.

The chief surgeon in operating room No. 1 followed Qin Sifeng and whispered: "The patient in operating room No. 3 is a little special. I originally thought it was a routine premature ventricular ablation, but I just discovered that the origin seems to be in the epicardium."

"Epicardium?" Qin Sifeng paused slightly, "We don't encounter many here! Which student with a dark face picked up this case?"

"It seems to be called Lu Chen." The surgeon in charge of operating room No. 1 said.

"Is it him?" Qin Sifeng was stunned and listened to the footsteps.

In the eyes of all the instructors in the training class, it was a sure thing that Lu Chen would advance to the next stage. Unexpectedly, Cheng Yaojin showed up halfway!

After all, he had won the second place three times in a row. Whether it was the students or instructors in the training class, everyone was very optimistic about Lu Chen.

"Did he give up?" Qin Sifeng thought to himself, "No, if he gave up, he wouldn't come to me."

The chief surgeon in operating room No. 1 continued: "Professor Qin, he did not give up, but came up with a way to insert a catheter from the epicardium through pericardial puncture."

When Qin Sifeng heard this, he frowned deeply at first, and then smiled, "This boy really knows how to do things, it's not easy!"

"That's why we called you over." The chief surgeon in operating room No. 1 said.

"Okay, let's go take a look." Qin Sifeng nodded slightly and continued walking towards the operating room No. 3.

…

In operating room three.

Lu Chen had already used a cardiac ultrasound machine to mark the area near the right ventricle.

As long as the catheter is punctured from here and the catheter is inserted, epicardial ablation can be performed.

However, this was the first time for Lu Chen to experience such ablation without fluid accumulation.

Taking advantage of Qin Sifeng's arrival, he was already training in the system's simulated surgery room.

Pericardiocentesis is one of the clinical skills that Lu Chen is familiar with, and his proficiency level has reached about 90%.

Now he will specifically remove the pericardial effusion and simply practice puncture without pericardial effusion.

Because of his previous foundation, Lu Chen's training process was relatively smooth.

At this time, Qin Sifeng arrived.

Wearing a surgical gown and a lead gown, he slowly walked into operating room No. 3.

"Professor Qin!" Lu Chen stepped forward immediately.

"Well, the origin of your patient's ventricular malfunction is in the epicardium?" Qin Sifeng said straight to the point.

"Yes." Lu Chen nodded helplessly, "I have had endometrium ablation many times, and it had a certain effect, but after the discharge was removed, the endometrium had long since recovered."

"So you think the origin of ventricular premature disease is in the epicardium?" Qin Sifeng glanced at Lu Chen.

"Well, to be more precise, the origin of ventricular premature disease is between the endocardium and the epicardium, but closer to the epicardium, so it has a certain effect on the endocardium, but it cannot be maintained." Lu Chen said slowly.

Hearing this, Qin Sifeng nodded slightly, "It makes sense. This kind of ventricular premature originating from the epicardium is very rare. This should be the first case our hospital has encountered this year!"

In the auditorium of the demonstration classroom, everyone was talking a lot.

On the big screen at this time, only the No. 3 operating room was shown, and the conversation between Lu Chen and Qin Sifeng was also broadcast.

"Epicardial ventricular premature beats?" Fang Ruzhang was shocked, "Director, we haven't encountered such a case in the third area of ​​the heart for several years."

Wan Jingshui nodded, "The last time was three years ago, when we encountered an epicardial ventricular premature beat."

"How did you deal with it then?" Fang Ruzhang asked again.

"I did a second operation." Wan Jingshui thought for a while and said.

...

In the catheterization room.

Qin Sifeng looked at Lu Chen with a smile, "It's not easy for you to see these things. The next operation is completely beyond the scope, so you don't have to do it. As the chief examiner of this assessment, I will apply for an additional assessment for you."

Everyone was stunned when they heard this.

Apply for an assessment again?

"Professor Qin, this is against the rules, isn't it?" said the surgeon in the No. 1 operating room. "Although none of us expected this situation, this is an assessment after all, and we need to bear these uncertainties."

"Really?" Qin Sifeng's eyes were like torches, UU reading wｗw.ｕukａnｓｈu.net "Then what do you think is the significance of our assessment?"

"This assessment is to select a group of excellent students." The surgeon in the No. 1 operating room paused and said.

"You said it yourself, to select a group of excellent students, not to embarrass them!" Qin Sifeng snorted coldly, "Take this epicardial ventricular premature beat as an example. If it were you, could you diagnose it and give corresponding treatment?"

The surgeon was stunned and did not reply for a while. He glanced at Lu Chen and was thinking in his heart, if it was him who encountered an epicardial ventricular premature beat, could he be as calm as Lu Chen and successfully interpret the cause of the ablation failure?

The answer is uncertain.

The surgeon in the No. 1 operating room himself did not dare to guarantee that he would be able to diagnose and treat it!

At this moment, Lu Chen suddenly said, "Professor Qin, let me try."

This voice seemed a little abrupt to everyone.

But Lu Chen's eyes were firm. He looked back at Qin Sifeng and said in a deep voice, "I am sure of pericardial puncture, and with the positioning of the cardiac ultrasound machine, the risk will be minimized!"
