Chapter 418 Passed the assessment!

Everyone turned their attention to Lu Chen.

A doubt arose in everyone's heart, who gave the young man in front of him the courage?

"You don't want the chance of the second assessment?" Qin Sifeng asked back.

"Yes, of course it's the best." Lu Chen smiled, "If not, then I have to win this patient for myself!"

"Good boy!" Qin Sifeng smiled and patted Lu Chen's shoulder, "Are you so sure?"

Lu Chen nodded slightly, but his eyes were unquestionable.

Pericardial puncture, this is also one of his most confident operations!

……

Show outside the classroom.

"Director, you mean that Lu Chen wants to have a pericardiocentesis?" Fang Ruzhang was a little surprised.

To be honest, the current specialties are becoming more and more refined.

Operations such as pericardiocentesis and thoracentesis are performed in dedicated ultrasound intervention rooms.

The Cardiology Department performs pericardiocentesis in the ward itself, and this kind of opportunity is less and less, because the current doctor-patient relationship does not tolerate any risk.

Fang Ruzhang has not done pericardiocentesis for a long time, let alone this kind of puncture without effusion, the difficulty will only be higher!
"That's right, didn't you see that he has been positioned by echocardiography?" Wan Jingshui said, "He wants to put the catheter in the epicardium through pericardiocentesis, and then perform ablation."

"But our assessment this time is for electrophysiological interventional surgery, not puncture?" Fang Ruzhang was taken aback, "Is this embarrassing?"

At this time, Yao Jie on the side spoke up.

Although she knew that it was not appropriate to speak out in this occasion, she still couldn't help but speak out.

"Senior brother Lu Chen, he, he passed through blindly before!"

"Ah?" Fang Ruzhang looked back at Yao Jie, "What did you say? Blind piercing? Blind piercing for pericardial puncture?"

"Yeah." Yao Jie couldn't help nodding, "It was in the elevator..."

After Yao Jie briefly explained the situation at that time, Fang Ruzhang and Wan Jingshui looked at each other, and both could see the shock in each other's eyes.

It is one thing to be able to puncture, but another to dare to wear it!

And it's still blind!

How much courage is needed for Lu Chen to perform blind penetration under such circumstances.

"Everyone in the cardiology department knew about this matter..." Yao Jie emphasized in a low voice.

"Yeah, how did I forget that he is the champion of the National Medical Skills Competition..." Fang Ruzhang shook his head slightly.

"It seems that I still underestimated him!"

Wan Jingshui focused his attention on the big screen again. He is now more and more interested in this student named Lu Chen!

Maybe, he can really succeed...

……

catheter room.

After informing the patient and family members of the risks and obtaining consent for the operation, Lu Chen began to perform pericardiocentesis under Qin Sifeng's guidance.

Everyone else came to the outside of the catheterization room, and watched the situation inside the room through the glass window.

"This kid is really tough!" The chief surgeon in the No. [-] operating room shook his head helplessly, "Actually, if Professor Qin insists on giving him a second chance for the assessment, then I can't object!"

"Don't tell me, I looked at this student's eyes, his calmness is really not fake." Another doctor said, "Besides, it's not like you didn't see the speed of his blood vessel puncture before. With such a technical level, going for a pericardial puncture is not easy?"

The doctor in the No. [-] operating room thought about it, and the words were not rough.

Everyone was thinking about the difficulty of pericardial puncture, but they forgot the speed and accuracy of Lu Chen's blood vessel puncture before!

"Yu Hewei, do you think Lu Chen can do it?"

The other assessment students gathered around Yu Hewei, and now Lu Chen's grades have determined their rankings.

From the heart, most of them don't want Lu Chen to pass the examination.

Yu Hewei narrowed his eyes, and he stared closely at Lu Chen in the catheterization room, "I hope Lu Chen can pass."

Only in this way, he will have a sense of urgency.

Otherwise, he has been leading by a large margin in the training class, and he is a little slack.

……

At this time, Lu Chen had washed his hands again and put on his gloves.

"Have you selected the puncture point?" Qin Sifeng stood beside him and asked softly.

"Well, I've marked it." Lu Chen made a mark on the surface of the right atrium of the patient's heart.

"Then let's get started."

Qin Sifeng stood beside Lu Chen like a door god, ready to take over his job at any time.

Lu Chen breathed lightly and adjusted his state.

In my mind, the process of piercing kept appearing.

Anesthesia, puncture, needle insertion, catheter access.

Every step appeared so clearly in my mind.

After the anesthesia was over, Lu Chen started to puncture.

This puncture is different from conventional pericardiocentesis,
When pericardiocentesis is performed with effusion, the puncture needle goes a little deeper, and there is no major problem.

But for this patient Lu Chen, once the puncture is a few tenths of a millimeter deeper, it may injure the myocardial tissue!

At this moment, Lu Chen moved.

He held the puncture needle in his right hand, and the needle was inserted at the mark on the body surface!

Lu Chen stared at the operating needle in his hand, and slowly pushed it forward.

Qin Sifeng was not idle at the side, he held an echocardiogram probe and "guided" Lu Chen's puncture.

This is also a double layer of insurance!
Lu Chen can understand the dynamics of the puncture needle through the real-time image of the ultrasound.

"It's in position!" Feeling some resistance, Lu Chen immediately paused the needle insertion.

On the screen of the ultrasound machine, the puncture needle also reached the predetermined position smoothly.

"Huh..." Lu Chen also heaved a sigh of relief in his heart.

It seemed a simple operation, but Lu Chen's palms were sweating.

The remaining step is to enter the catheter.

Lu Chen didn't dare to relax at all. He took the catheter handed over by the nurse and slowly inserted it into the puncture needle.

Under the guidance of the CARTO cardiac three-dimensional electrophysiological navigation system, he sent the catheter to the opposite side of the previous ablation site on the endocardial surface.

After the catheter entered, the puncture needle was removed.

"Okay!" Lu Chen whispered, "The puncture was successful!"

Qin Sifeng nodded slightly aside, and gave Lu Chen an appreciative look.

Although these steps take a short time, the operations involved are not simple.

The technique, the direction of the force, the position, there must be no error in every point!
Outside the catheter room, everyone was silent.

Everyone never expected that Lu Chen's piercing would be so easy.

Yu Hewei looked at Lu Chen in the catheterization room, with a smile on his lips, "Lu Chen, you really didn't disappoint me! The next second stage will be interesting!"

And in the demonstration classroom.

Fang Ruzhang also realized that the blind piercing of the pericardium that Yao Jie said had some credibility!
Lu Chen's proficient operating skills are no longer comparable to ordinary attending doctors or deputy chief physicians.

Without years of clinical training, it is absolutely impossible to have this kind of proficiency!
Wan Jingshui also shook his head slightly, and sighed: "I really don't know how Lu Chen trains?! Can Jinghua Second Academy cultivate such outstanding talents?"

……

Catheterization room, in the third operating room.

When the catheter reached the designated position, Lu Chen started the discharge operation.

This time, after the discharge ablation, the chamber disappeared!
In order to avoid the previous situation, Lu Chen consolidated and ablated several times, and the effect was obviously better than before.

A few minutes of extended observation time, there are still a small number of premature beats, consistent with the preoperative morphology.

Lu Chen adjusted the position of the catheter calmly, and detected the fragmentation late potential at a position slightly outside and down, which indicated that it was closer to the origin point!

After continuous discharge ablation and consolidation again, VZZA finally completely disappeared!

However, the surgery is not over yet.

After ablation, induction experiments must be performed to ensure that the arrhythmia will not recur easily.

Lu Chen stopped the discharge, asked the patient to hold his breath, and injected isoproterenol at the same time, trying to induce premature ventricular discharge.

Observed again for more than 20 minutes, on the ECG monitor, I did not see a ventricular premature!
Lu Chen walked off the operating table when all of them were in normal sinus rhythm.

The ablation of the "internal and external" attack was successful!

At this time, the catheter is outside.

"Lu Chen, congratulations, you passed the test!"

Everyone was stunned for a few seconds. Led by Qin Sifeng, the whole catheterization room burst into endless applause!

　After get off work, I still have to drink with the leader, there is no way!
　　I have gained weight recently...

　　There are two more today, everyone go to bed early.
