Seeing that Liu Dongfang was about to puncture, the instrument nurse on the side hurriedly asked.

"Director Liu, do I need a dilator to expand the skin when I place a catheter?"

"No!"

Liu Dongfang shook his head and said: "The dilator will damage the skin and have an impact on the child's future healing. ”

"However, if you don't use it, it's likely to lead to catheter failure!"

The nurse's eyes were full of worry.

After all, the ECMO that will be taken in a while has extremely strict standards for the tubing itself and the position of the catheterization!

Discounted and twisted tubing will affect the speed of the blood pump!

The deviation and adherence of the catheter placement position will affect the blood flow rate!

Both will have a series of complications such as insufficient cardiac output, unable to maintain the oxygen supply required by the body, and a series of complications such as increased lactate, which will eventually lead to the failure of the operation!

"Don't worry!"

"Since I said no, you can wait and see. ”

Liu Dongfang smiled confidently!

His catheterization of the femoral vein has long reached the point of perfection.

The sharp needle, under the reflection of the shadowless lamp, appears to sparkle.

Liu Dongfang is positioned with his left hand and holds a needle in his right hand!

A bright needle pierces directly into the skin!

Liu Dongfang did not hesitate.

Push your fingers hard.

I felt an elastic touch coming from the needle.

As the needle tube gradually gushed out a bright red.

A smile hung on the corner of Liu Dongfang's mouth.

"Prepare the guidewire-guided tube!"

After that, Liu Dongfang stretched out his hand and prepared to take the guidewire!

But he waited left and right, and the guidewire that should have appeared in his hand was nowhere to be seen.

This abnormality made Liu Dongfang couldn't help frowning.

"Huh?!"

"Sorry, I was distracted just now!"

The instrument nurse, who had just woken up from a dream, hurriedly handed the guidewire in the puncture box to Liu Dongfang.

At this time, her face was flushed and her heart was pounding!

In addition to the uneasiness, there is more shock and consternation in my heart!

She never thought that femoral vein puncture and catheterization would be so simple!

You know, it usually takes at least about ten minutes to puncture like this.

When encountering some difficult blood vessels, it is like a skinny little girl in front of her, and it will take at least 30 minutes to get down!

But what about Liu Dongfang?

From puncture to catheterization, it takes no more than two minutes before and after!

This is still a femoral vein puncture completed without the assistance of a dilator, relying on personal experience and surgical skills!

"It's just too strong!"

The instrument nurse couldn't help but say.

However!

The anesthesiologist, who had been silent, suddenly spoke.

"Director Liu, the blood in your catheter is a little wrong, right? ”

"What's wrong?"

At this time, Liu Dongfang had already threaded the guidewire into the blood vessel and was ready for catheter placement.

Seeing this, the anesthesiologist hesitated for a moment, but still said: "Generally, if the intravenous catheter is placed, the blood drawn will be dark red!"

"But the blood you just came out of the catheter is so red, it's arterial blood at all!"

The anesthesiologist swears.

After all, his work, in addition to anesthesia medication and routine intubation, general deep venous catheterization also belongs to the category of anesthesiologists!

For example, subclavian vein puncture and internal jugular vein catheterization are operated by anesthesiologists on the operating table!

If it weren't for the fact that this catheterization was too special, otherwise it wouldn't be Liu Dongfang's turn to do it!

"Arterial blood?"

After listening to the anesthesiologist's remarks, Liu Dongfang smiled and did not explain.

But the movement of his hands was not slow.

Moment!

The catheter has been followed along the guidewire and into the blood vessel, and the femoral vein catheterization has been completed!

"Director Liu, you?!"

Seeing this, the anesthesiologist was obviously stunned!

Immediately, a wave of anger rose in his heart.

He had obviously explained it just now, but Liu Dongfang ignored it and still completed the catheterization!

This kind of self-doing behavior naturally makes the anesthesiologist a little uncomfortable!

"Director Liu, the nature and characteristics of arteries and veins, I don't need to say, you also know!"

"Once the movement and static are mixed, not to mention that the treatment effect is greatly reduced, and even worse, there will be serious complications!"

"At that time, the operation was unsuccessful, and the girl's life was put into it in vain, which is a bit too much to lose!"

The anesthesiologist's tone became colder and colder, and in the end, they all began to accuse Liu Dongfang sharply!

After all, in his opinion, how could a person who couldn't even distinguish between arteriovenous and vascular vessels complete such a complicated operation!

Suddenly, the scene was embarrassing!

The instrument nurse stood in place, looking torn!

"Why don't you check your blood gas first and see if the partial pressure of oxygen is normal?"

The nurse suggested.

As soon as these words came out, the anesthesiologist at the bedside immediately answered.

"Yes, wait for the POCT test results to come out before proceeding to the next step, only in this way is the safest!"

But!

Their suggestion was directly rejected by Liu Dongfang!

"Absolutely not!"

Liu Dongfang shook his head, his expression extremely serious.

"A girl's blood vessels are already fragile, and over time, the elasticity will decrease, which will inevitably affect the operation of the machine!"

"And if the probe stays in the blood vessels, it will also increase the chance of bloodstream infection!"

Seeing that the two sides did not agree on the same opinion, the anesthesiologist seemed a little anxious!

"Are you so confident?!"

"I don't doubt it at all, if this needle pierces the artery, the consequences will be unimaginable!"

Liu Dongfang faced the question from the anesthesiologist and said with a smile: "I'm sorry, I've always been so confident!"

He took out a tube of blood and put it on the operating table: "If you have to insist on your opinion, the blood can be handed over to you for examination, but I will not wait for your results to come out!"

In other words, Liu Dongfang didn't care about the result of blood at all.

Because in his opinion, these are all unnecessary things!

If you don't show mercy, you will be furious with the anesthesiologist!

"You're not confident, you're arrogant!"

The anesthesiologist grimaced and took the bright red tube off the operating table.

"Deliver it to me!"

"Once the results are found out by the laboratory department, let me know as soon as possible!"

The anesthesiologist gave the blood to the roving nurse and told her to send it for testing as soon as possible.

The little nurse who got the order, without saying a word, opened her legs and ran towards the laboratory department.

At the same time, ECMO, which had been wiped with chlorine disinfectant and irradiated with ultraviolet light, was finally pushed into the operating room.

The body is extremely smooth and has a cold sheen.

Arm-thick pipes are staggered, giving people a sense of thickness.

"So this is ECMO extracorporeal oxygenated membrane lung?"

Everyone present was amazed.

They look at them like curious babies, as if they are looking at a priceless treasure.

Seeing this scene, Huang Sen's expression was a little proud.

After all, like this only machine in the city, it is very well kept on weekdays, so many people have never seen it!

Even Huang Sen himself, when he saw this machine for the first time, had the same expression.

"This is the ECMO you've come to expect!"

"It can help people maintain the normal oxygenation supply of the body without a heartbeat by simulating the lungs and heart of the human body!"

"This is the membrane lung (artificial lung) and the blood pump (artificial heart)"

Just as Huang Sen was about to continue to explain the working principle and basic equipment of ECMO, a cold voice suddenly sounded.

"Lao Huang, I'll talk about this later!"

"Now grab the connection line and get ready to get on the plane!"

Liu Dongfang looked a little impatient.

After all, I'm waiting for surgery here, but Huang Sen is not finished, it's a delay!

"Lao Huang?!"

After hearing this, Huang Sen was stunned at first, and then his face changed slightly.

He is also the emergency manager of the best hospital in Nakajima City, so how can he not be called Teacher Huang!

However!

How did it get to Liu Dongfang's mouth and become Lao Huang?!

Isn't that scolding?

"Okay, Lao Huang, it's important to save people!"

"I'm waiting for you!
