Seeing Liu Dongfang preparing for puncture, the instrument nurse on the side quickly asked.

"Director Liu, do you need a dilator to expand the skin when inserting the catheter?"

"Need not!"

Liu Dongfang shook his head and said: "The dilator will damage the skin and affect the child's future healing."

"However, if it is not used, it is likely to cause failure of the catheter placement!"

The nurse's eyes were full of worry.

After all, the ECMO that will be put on soon has extremely strict standards for the pipeline itself and the location of the tube!

Broken or twisted pipes will affect the running speed of the blood pump!

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

Both of them will suffer from insufficient cardiac output, unable to maintain the oxygen supply required by the body, and will suffer from a series of complications such as increased lactic acid, ultimately leading to surgical failure!

"rest assured!"

"Since I said no, just wait and see."

Liu Dongfang smiled confidently!

He has already reached the level of proficiency in the placement of femoral vein cannulae.

The sharp needles sparkle under the reflection of the shadowless lamp.

Liu Dongfang is positioning with his left hand and holding the needle with his right hand!

The bright needle penetrates directly into the skin!

Liu Dongfang didn't hesitate at all.

Push your fingers hard.

I only felt a elastic touch coming from the needle tube.

As a bright red color gradually emerged from the needle.

A smile appeared on Liu Dongfang's lips.

"Prepare to enter the tube under guidewire guidance!"

Having said that, Liu Dongfang stretched out his hand, ready to take the guide wire!

But he waited and waited, but the guide wire that should have appeared in his hand was still missing.

This abnormality made Liu Dongfang couldn't help but frown.

"ah?!"

"Sorry, I was distracted just now!"

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

At this time, her face was flushed and her heart was beating fast!

In addition to being uneasy, I was more shocked and surprised!

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

You know, a puncture like this usually takes at least ten minutes.

When encountering some difficult blood vessels, just like the skinny little girl in front of me, it will take at least thirty minutes to do it!

But what about Liu Dongfang?

From puncture to catheter placement, it takes no more than two minutes!

This is a femoral venipuncture performed without the assistance of a dilator, relying solely on personal experience and surgical skills!

"It's simply too strong!"

The equipment nurse couldn't help but say.

However!

The anesthesiologist, who had been silent until now, suddenly spoke.

"Director Liu, there's something wrong with the blood in your catheter."

"What's wrong?"

At this time, Liu Dongfang had already inserted the guide wire into the blood vessel and was preparing to insert the catheter.

Seeing this, the anesthesiologist hesitated for a moment and then said: "Generally, when a venous catheter is inserted, the blood drawn out will be dark red!"

"But the blood that just flowed out of the catheter was too red. It was simply arterial blood!"

The anesthesiologist vowed.

After all, his job, in addition to administering anesthesia drugs and routine intubation, general deep vein catheterization also falls within the scope of an anesthesiologist!

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

If it weren't for the special nature of this catheter placement, it wouldn't have been 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 movements of his hands were not slow.

moment!

The catheter has followed the guide wire and entered the blood vessel, completing the femoral vein catheterization!

"Director Liu, you?!"

Seeing this, the anesthesiologist was obviously taken aback!

Then a surge of anger arose in his heart.

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

This kind of behavior that goes its own way naturally makes the anesthesiologist a little embarrassed!

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

"Once movement and stillness are mixed, the therapeutic effect will be greatly reduced, and worse, serious complications will occur!"

"At that time, if the operation fails and the girl's life is wasted, it will be too much!"

The anesthesiologist's tone became colder and colder, and in the end, he began to accuse Liu Dongfang harshly!

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

Suddenly, the scene became awkward!

The instrument nurse stood there, looking in a dilemma!

"How about checking the blood gas first to see if the partial pressure of oxygen is normal?"

The nurse suggested.

As soon as this was said, the anesthesiologist at the bedside immediately answered.

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

but!

Their suggestions were directly rejected by Liu Dongfang!

"Absolutely not!"

Liu Dongfang shook his head, his expression extremely serious.

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

"And if the probe remains in the blood vessel, it will also increase the chance of blood tract infection!"

Seeing the disagreement between the two parties, the anesthesiologist seemed a little anxious!

"Are you so confident?!"

"I have no doubt at all. If this needle pierces an artery, the consequences will be disastrous!"

Facing the doubts from the anesthesiologist, Liu Dongfang smiled and said: "Sorry, I've always been so confident!"

He took out a tube of blood and put it on the operating table: "If you insist on your opinion, I can give you the blood for testing, but I won't wait for your results!"

The implication is that Liu Dongfang doesn't care about the consequences of blood at all.

Because in his opinion, these are unnecessary things!

If you are merciless, the anesthesiologist will be furious!

"You are not confident, but arrogant!"

The anesthesiologist took the bright red tube off the operating table with a cold face.

"Help me deliver urgently!"
