Chapter 413: Passed the Test!

Remember [New] in one second! Everyone turned their eyes to Lu Chen.

Everyone had a doubt in their hearts. Who gave this young man the courage?

"You don't want the second chance to be assessed?" Qin Sifeng asked back.

"Yes, of course it's the best." Lu Chen smiled, "If not, then I have to fight for 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.

...

Outside the demonstration room.

"Director, do you mean that Lu Chen wants to do 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 all completed in special ultrasound intervention rooms.

There are fewer and fewer opportunities for the cardiology department to do pericardiocentesis in the ward, because the current doctor-patient relationship does not allow for any risk.

Fang Ruzhang hadn't done pericardial puncture himself for a long time, not to mention this kind of puncture without effusion, which would be even more difficult!

"Yes, didn't you see that he had already used cardiac ultrasound to locate it?" Wan Jingshui said.

"But our assessment this time is about electrophysiological intervention surgery, not puncture?" Fang Ruzhang was stunned, "Is this a problem?"

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

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

"Brother Lu Chen, he did it blindly before!"

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

"Yeah." Yao Jie nodded constantly, "It was in the elevator at that time..."

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

Knowing how to puncture is one thing, and whether you dare to do it is another!

Lu Chen needed so much courage to do it blindly at that time.

"Everyone in the cardiology department knew about this at the time..." Yao Jie whispered.

"Yeah, how could I forget that he was the champion of the national medical skills competition..." Fang Ruzhang shook his head slightly.

"It seems that I still underestimated him!" Wan Jingshui refocused his eyes on the big screen. He is now more and more interested in this student named Lu Chen!

Maybe he really succeeded!

...

In the catheter room.

After notifying the patient and his family of the risks and obtaining consent for the operation, Lu Chen began to perform pericardiocentesis under the guidance of Qin Sifeng.

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

"This kid is really tough!" The surgeon in the No. 1 operating room shook his head helplessly, "In fact, if Professor Qin insists on giving him a second chance to take the test, then I can't object!"

"You know what, I see from the look in this student's eyes that his calmness is really not fake." Another doctor said, "Besides, you haven't seen his speed in vascular puncture before. With this level of technology, pericardial puncture should be a piece of cake?"

The doctor in the No. 3 operating room thought about it and realized that this was a rough but true statement.

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

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

The other students who were taking the test gathered around Yu Hewei. Now Lu Chen's results determined their ranking.

In their hearts, most of them didn't want Lu Chen to pass the test.

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

Only in this way would he feel a little bit of urgency.

Otherwise, he would have been a little lax after leading by a large margin.

…

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

“Have you chosen the puncture point?” Qin Sifeng stood beside him and whispered.

“Well, I’ve marked it.” Lu Chen marked 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 work at any time.

Lu Chen breathed gently and adjusted his state.

In his mind, the puncture process continued to appear.

Anesthesia, puncture, needle insertion, and catheter insertion.

Every step appeared so clearly in his mind.

After anesthesia, Lu Chen began to puncture.

This puncture is different from conventional pericardial puncture.

When pericardial puncture is performed with effusion, the length of the puncture needle does not make any difference.

But for Lu Chen’s patient, the puncture must be a few tenths of a millimeter deeper.

That could damage the myocardial tissue!

At this moment, Lu Chen moved.

He held the puncture needle in his right hand and inserted the needle at the marked point on the body surface!

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

Qin Sifeng was not idle at the side either. He held the cardiac ultrasound probe and "guided" Lu Chen's puncture.

This is also a double insurance!

Lu Chen can understand the dynamics of the puncture needle through the real-time ultrasound image.

"It's in place!" Lu Chen felt some resistance and immediately stopped inserting the needle.

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

The remaining step is to enter the catheter.

Lu Chen did not 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 endocardial ablation site.

After the catheter entered, the puncture needle was withdrawn.

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

Qin Sifeng nodded slightly and cast an admiring look at Lu Chen.

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

The technique, force direction, and position, there must be no error at every point!

Outside the catheter room, everyone couldn't help but breathe a sigh of relief.

Yu Hewei looked at Lu Chen in the catheter room, and a smile appeared at the corner of his mouth, "Lu Chen, you really didn't let me down! The next second stage will be interesting!"

And in the demonstration room.

Fang Ruzhang also realized that Yao Jie's blind pericardial puncture was somewhat credible!

Lu Chen's skilled operation skills are not comparable to those of ordinary attending physicians or deputy chief physicians.

Without years of clinical training, it is absolutely impossible to have such proficiency!

Wan Jingshui also shook his head slightly and sighed: "I really don't know how Lu Chen was trained! Can Jinghua Second Hospital cultivate such excellent talents?"

...

Catheterization room, operating room No. 3.

When the catheter reached the designated position, Lu Chen began to perform discharge operations.

This time, after discharge ablation, the premature beats disappeared!

In order to avoid the previous situation, Lu Chen consolidated the ablation several times, and the effect was significantly better than before.

After extending the observation time for a few minutes, a small number of premature beats still appeared, which was consistent with the preoperative morphology. UＵ看书www.uukanshu． net

Lu Chen adjusted the catheter position calmly and measured the fragmented late potential at a position slightly outside and below, which indicated that the place was closer to the origin!

After continuing the discharge ablation and consolidation, the premature beats finally disappeared completely!

However, the operation was not over yet.

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

Lu Chen stopped the discharge and asked the patient to hold his breath, while injecting isoproterenol to try to induce premature ventricular contractions.

After observing for more than 20 minutes, no premature ventricular contractions were seen on the ECG monitor!

Lu Chen walked off the operating table only when the heart rhythm was normal.

The "inside and outside" ablation was successful!

Outside the catheter room at this time.

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

Everyone was slightly stunned for a few seconds, and under the leadership of Qin Sifeng, the entire catheter room rang with long-lasting applause!
