Chapter 1057 Glasses fell all over the floor

The operation has begun. When Director Li put the medical record clip on the operating table, he suddenly saw that the imaging had begun on the screen.

What's the thing?

Director Li's hand suddenly numb.

On the screen, the micro guidewire is placed in the right ventricle and pulmonary artery...

At the same time, Zhou Congwen's voice came from the intercom.

"The microguidewire is selected from 0.014" to 0.038", with a length of 150-180 cm soft or hard loach guidewire, and cross the narrow pulmonary valve along the right heart catheter and enter the distal end of the pulmonary artery to establish a track."

"Be sure to pay attention to gentle operation, try not to touch the blood vessel wall or right ventricle."

Zhou Congwen's voice was very soft, but it felt like thunder rolling in Director Li's ears.

What does a guide wire mean? Try not to touch the blood vessel wall or right ventricle!

What,

damn it,

Try not to touch the blood vessel wall or right ventricle when asked!

Director Li really wanted to grab Zhou Congwen's neck and ask him, "What, fuck, call me, try not to touch the blood vessel wall or right ventricle!"

The blood vessels in the human body are winding and tortuous, and the guide wires are walking in the blood vessels. It is already a very strong surgical technique to be able to choose from them in place.

Many times, microguidewires rely on the blood vessel wall and other tissue structures to provide the direction of reaction force conversion.

This is the most basic common sense.

Zhou Congwen's request actually required the guide wire not to touch the blood vessel wall!

Director Li stared at the screen in a daze. He knew what Zhou Congwengang said - to prevent stimulating the ventricular wall from irradiating the tract spasm, or ventricular arrhythmia.

But that's not human operations at all.

However, when everything appeared in front of him, Director Li would not be questioned.

The 0.035" guidewire is almost invisible, as thin as an artifact. This shadow floats in the pulmonary artery and the right ventricle, and has no contact with the blood vessels and the heart.

Even the 0.035" guidewire did not touch the narrow pulmonary valve!

This is also...this is also...

Director Li seemed to have not woken up, and was still dreaming, looking at the screen and the micro guidewire as if he was still dreaming.

Then the heart catheter went down and the angiography began.

Cardiocatheography can clearly show that the pulmonary valve is severely stenosis, with the maximum open valve inner diameter of only 1.7mm, and the pressure difference between the right ventricle and pulmonary artery is 134mmHg, which is almost consistent with the 137mmHg measured previously.

"Here, the ratio of balloon diameter to pulmonary valve annulus diameter is 1.2 to 1.4."

Zhou Congwen's voice floated out again.

"We used a 10mm×20mm balloon to expand the pulmonary valve of the child."

"Sent into the balloon catheter along the track so that the center of the balloon is exactly on the valve, and dilate the pulmonary valve with a pressure of 3 to 4 atm 2 to 3 times."

"Please note here that you must not rush to dilate the balloon first, but use dilution contrast agent to dilate the pulmonary valve 2 to 3 times with a pressure of 3 to 4 atm."

"The principle has been explained before, just remember it. If you do too much surgery, you will understand it with a little memory."

Director Li was stunned, and he had never heard of what Zhou Congwen said.

In Director Li's understanding, the most awesome technique is balloon dilation, and he also prays that he must not have any complications.

As for using diluted contrast agent to punch the valve, this incredible way...

"Director Zhang?" Director Li whispered.

But Zhang You didn't say anything. He looked at the screen intently and didn't hear Director Li's words at all.

When will you show off and when will you learn, Zhang You can know clearly.

How wonderful the surgery was, it was meaningless to Zhang You.

I can’t watch it every day, and I can’t be shocked and dropped every day. After watching too much, I think this is the case even if I have awesome surgery.

Besides, if you don’t know anything, just ask Zhou Congwen directly. He never hides his own private skills.

It’s just that Zhang You can’t do it himself.

Not only Zhang You, but Tengfei also feels that she will never be able to achieve Zhou Congwen's level in her life.

After flushing the diluted contrast agent, the balloon expands continuously to open the narrow pulmonary valve.

Director Li was extremely shocked.

Shouldn’t this step be cautious and dilate the pulmonary valve a little bit like walking on thin ice? If there is any stimulation, it is also easy to treat.

Grey sweat began to emerge from his face without realizing it.

Half of it was caused by excitement, and the other half was caused by Director Li's fright.

Director Li didn't even understand half of the operation.

"It's almost like that." Zhou Congwen's voice came from the intercom, "Now, the transvalve pressure is measured. If it is less than 25, the operation will be successful. I estimate that the transvalve pressure of the child is between 18-20."

After Director Li heard Zhou Congwen's confident words, his heart seemed to be pinched by an invisible big hand, and even the most basic blood circulation could not be supplied in sufficient supply.

Is this the end?

What exactly did Zhou Congwen do? Why did the operation end?

If the patient insists on undergoing surgery in the first year of Medical College, Director Li can be sure that he will not be able to get out of the hospital for 5-6 hours, if the patient's life is really great.

But in Zhou Congwen's hands, it was over at the beginning...

Director Li bent down and wanted to get close to the screen and take a closer look.

After all, the micro guide chosen by Zhou Congwen is too thin, and Director Li is not presbyopia yet, but it is difficult to easily see the micro guide with his vision...

Bent over, before Director Li could get close to the screen, his glasses slid down the sweat on his face.

Director Li was looking at the screen with all his attention, but he didn't expect his glasses to fall off.

Before he could even save the action, he heard a "pop" sound, and his glasses fell to the ground innocently.

Director Li was confused when he squatted down in panic and picked up his glasses.

After the operation was completed, it seemed that it only took less than 15 minutes, which was shorter than the 30 minutes Zhou Congwen said before.

Even if the time and finishing work of measuring transvalve pressure are added, it is estimated that it will only be about 25 minutes.

How could it be done so quickly?

His heart was in a mess.

The operation...Director Li didn't know how to describe it, and there was a voice deep in his heart telling him something seemed to be wrong.

The sound became louder and louder, but Director Li was confused. He thought that it must be because the operation was done well, so that he was scared that his glasses fell to the ground.

The moment Director Li squatted on the ground and picked up glasses, he was shocked to remember a picture just now - Zhou Congwen continuously expanded the balloon, and the vital signs of the child displayed on the screen in the operation room did not change at all!

Even the heart rate has not changed!

This is impossible, absolutely impossible!

Even if there are no arrhythmias such as ventricular fibrillation, it is natural that the heart rate changes, at least it should be faster.

But the value is there, and there is no change at all...

Director Li squatted on the ground, pinching his glasses with his hands, and holding his head up and motionless.

"The cross-flap pressure of 20 mm Hg is done!" Zhang You clenched his right fist and smashed it on his left palm, saying loudly.

Then he took a step back, but was tripped by Director Li who was squatting on the ground behind him.
Chapter completed!
