Chapter 422: Thrilling

Remember [New] in one second!     On the bed, the patient's face was full of pain.

Lu Chen immediately stepped forward and walked to the operating table.

At this time, the patient was already lying on the operating table, and the surgeon had completed the puncture.

"What's going on?" Lu Chen frowned tightly.

A little nurse next to the bed said: "The patient's ventricular tachycardia just now occurred again, and the blood pressure dropped to hg!"

Ventricular tachycardia, a highly malignant arrhythmia, has a very high mortality rate!

If ordinary people have a series of ventricular tachycardia, it would be very dangerous.

Not to mention, with this kind of continuous ventricular tachycardia, the patient may go into shock or even die suddenly at any time!

"The patient's ventricular tachycardia has stopped, but the blood pressure has not risen yet, and he is still in a state of shock."

Lu Chen then understood the reason for the three minus signs in the patient's life value.

If the ventricular tachycardia is allowed to occur, the patient's life value will definitely continue to decline.

"Time is urgent, wait until the blood pressure rises to normal, and start dry pericardiocentesis immediately!" Lu Chen said in a deep voice.

"Okay." Yu Hewei nodded seriously and brought the pericardiocentesis kit.

This time, although Lu Chen was only an assistant, he was actually the real surgeon, and Yu Hewei was his assistant.

Since the last time he encountered this ventricular tachycardia originating from the "epicardium", Lu Chen went back and conducted targeted simulation training.

Dry pericardiocentesis is very difficult because there is no effusion.

The direction of the guidewire must be very precise. If you are not careful, you may puncture the heart or coronary vessels!

After Lu Chen trained several times, he finally mastered this skill.

...

After the ventricular tachycardia stopped, the patient's blood pressure gradually recovered, and the ablation operation officially began.

With Yu Hewei as an assistant, Lu Chen did not need to do the disinfection and draping before the operation.

It was not until the puncture that Yu Hewei gave up his position.

"Lu Chen, be steady. If there is any abnormality, we will withdraw the guidewire!"

Outside the catheter room, Qin Sifeng said to the room through the microphone.

Lu Chen did not look back, but nodded slightly in response.

Recalling the training process in the simulated operating room, Lu Chen took a deep breath, his eyes were unusually firm.

On the side, Yu Hewei even felt that Lu Chen's momentum had changed.

He thought he was not as confident as Lu Chen.

Holding the puncture needle in his right hand, under the guidance of the ultrasound probe, Lu Chen began to perform pericardial puncture.

The needle pierced the skin and entered the pericardium layer by layer.

Lu Chen's movements were very gentle, without any drag.

Everything seemed to be moving in a good direction.

But at this moment, the ECG monitor next to the patient sounded another "beep" alarm!

"Oh no, ventricular tachycardia again!" Yu Hewei shouted secretly.

Outside the catheter room, everyone saw the changes on the ECG monitor.

On the ECG monitor, all turned into ventricular tachycardia waveforms!

What worried everyone was that the patient's blood pressure collapsed again!

From 100/60mmhg just now, it dropped directly to 50/30mmhg.

On the operating table, the patient groaned.

Ventricular tachycardia occurred during the operation, which was really fatal!

"What should we do? Should we withdraw the guidewire?" Yu Hewei turned his head and looked at Lu Chen.

Forcing the puncture is extremely risky.

If the patient has a large movement, it is very likely that the guidewire will penetrate the pericardium, and even gods will find it difficult to save him!

However, if the guidewire is withdrawn, the next puncture may be more difficult.

Moreover, there is no guarantee that the patient's arrhythmia will not recur again during the next operation!

Lu Chen also noticed the sudden change, and he did not hesitate at all, and his hands did not slow down at all.

"Brother Yu, watch my operation. Once I find the origin of the ventricular tachycardia, you will cooperate with me and perform ablation immediately!"

"Ah?" Before Yu Hewei could react, Lu Chen completely penetrated the guidewire into the pericardium.

The origin of the arrhythmia has begun to be displayed on the electrocardiogram next to the operating table.

"Quick, discharge ablation!" Lu Chen said hurriedly.

Yu Hewei's brain was a little empty at this time, but he still followed Lu Chen's instructions and mechanically performed the discharge ablation operation.

"Nurse, open another intravenous channel!" Lu Chen said, "Then use a group of dopamine, and make sure to stabilize the blood pressure!"

"Received!"

...

Outside the catheter room.

Everyone was even more nervous than Lu Chen and Yu Hewei in the catheter room.

However, in addition to being nervous, everyone began to discuss.

"Lu Chen is really brave!"

"Directly perform radiofrequency ablation during ventricular tachycardia, maybe few people dare to do this operation?"

"Which hospital is Lu Chen from?"

"I remember it seems to be from Jinghua, and he is still a graduate student. This kind of talent, I want our director to dig it out!"

Qin Sifeng looked at the calm Lu Chen, and his heart was very hot. At this moment, he especially wanted to dig Lu Chen to their Kyoto University First Affiliated Hospital.

"That old guy Ouyang Ming is really lucky!" Qin Sifeng shook his head helplessly.

The ability demonstrated by Lu Chen is not only his skilled operating techniques, but also his ability to adapt to changing circumstances and remain calm and composed!

Technology is important, but as an interventional surgeon, what is more important is this kind of mentality of not being surprised by praise or criticism.

…

In the catheter room.

Sweat oozed from Lu Chen's forehead. In such a high-risk situation, it would be a lie to say that he was not nervous at all.

Fortunately, Yu Hewei cooperated very well. When the ablation was halfway through, the patient's ventricular tachycardia finally stopped!

Then, the blood pressure also rose to hg.

Lu Chen breathed a sigh of relief.

"Brother Yu, do the ablation." Lu Chen said, "I just detected that there are many origin points in the epicardium, and there are also in the endocardium. Bilateral ablation may be required!"

"Okay!" Yu Hewei nodded, and his face finally returned to normal.

He was frightened by Lu Chen's operation just now.

He asked himself in his heart, if he encountered this situation, he would definitely stop the operation and would not take such a risk!

However, the risk is proportional to the result.

Almost all the origin points of the patient in the epicardium have been found.

On the operating table, the patient's condition has calmed down.

His life value also gradually increased from the previous 54.

The three minus signs behind the life value also turned into one!

"Induce again!" Lu Chen ordered.

How to determine the success of ablation?

At this time, artificial induction is required. If arrhythmia cannot be induced, it proves that it is initially successful.

"Received." Yu Hewei nodded and began to inject drugs into the patient for induction experiments.

One minute...

Two minutes...

Five minutes...

Ten minutes...

On the ECG monitor next to the operating table, the patient's heart rhythm is always sinus rhythm, and no series of ventricular tachycardia can be seen!

"Congratulations, UU reading wwｗ.uukanshu.net system upgrade completion rate has increased!"

"Congratulations, received Yu Hewei's gratitude value +1!"

"Congratulations, received Qin Sifeng's gratitude value +5!"

"..."

A series of system prompts sounded, and Lu Chen's face also showed a relieved ablation.

The epicardial ventricular tachycardia ablation was successful!

At the same time, outside the catheter room, everyone burst into exclamations.

I don't know when, all the interventional doctors outside the catheter room came over to watch.

"Fuck! Really amazing, which master trained this young doctor?!"

"At his age, I don't even know what radiofrequency ablation is!"

"This doctor is not very old, he probably doesn't have a girlfriend, I beg for his contact information!"

...
