Four o'clock in the morning.

Shengbei Hospital, Emergency Department.

A half-human-tall, uniquely shaped machine is being removed from the ambulance.

"Pay attention to handle it gently, this piece of equipment can't be bumped into it!"

Huang Sen's eyes were staring at the device tightly, for fear that one would accidentally smash it!

"Brother Huang, don't worry, this machine, even if I sell the house, I can't afford to pay for it!"

"Naturally, you have to be careful!"

The agent of the instrument who is unloading is also full of energy, and he is afraid that the instrument will be damaged!

Finally!

After a lot of hard work, this only ECMO in the city has finally landed!

Seeing this, Huang Sen breathed a sigh of relief.

"Liu Dongfang, I brought the instrument, ready to dock!"

He turned his head to look at the emergency hall, but he didn't find any trace of Liu Dongfang at all.

"What a big shelf!"

Huang Sen snorted coldly!

He personally escorted such valuable equipment.

But Liu Dongfang is good, he doesn't even show his face!

Even if you don't want to see me, you should send someone to pick me up!

It's a big night, what's the matter with hanging us here!

Just when Huang Sen couldn't help but complain, not far away, a person hurriedly ran over!

He saw ECMO next to Huang Sen, and without saying a word, he was about to leave!

Such a move made Huang Sen completely anxious!

He grabbed the machine and stepped forward to stop, "What are you doing?"

Hearing this, the man's eyes were full of surprise, and he wondered, "Aren't you here to deliver the instrument?"

As soon as these words came out, Huang Sen's face suddenly changed.

He also worked as an inpatient in the emergency department of the city hospital!

Some of them have nearly twenty years of clinical experience!

It is also to master the maintenance and overhaul of first-aid equipment!

How did it get into his mouth and become a transmitter?

"I came all the way to send you equipment, not to mention the hard work, and now I don't even have a word of thanks, isn't it too much!"

Huang Sen was a little annoyed.

Even if you have a good relationship with the dean and say hello in advance, you can't meet without saying anything, just take something and have someone!

Just when Huang Sen was indignant, a cold voice sounded!

"Thank you!"

The man pulled his face, and after saying the words of thanks with a blank face, he was ready to push the device away again!

"Wait!"

With the stop again, Duan Kailiang, who was anxious, finally changed his face.

"I've thanked you, why didn't you let me go?"

"In the operating room, the child is waiting for surgery!"

"If Director Liu's time is delayed because of you, can you afford to take responsibility?!"

The accusations one after another directly stunned Huang Sen.

He glared, looked at Duan Kailiang, who was more than ten years younger than him, in disbelief, and muttered to himself.

"I'm here to help, not to make trouble!"

"This person's emotional intelligence is made of stone!"

But!

Following his words, Huang Sen suddenly reacted.

"Kid, what are you going to do?"

Faced with the inquiry, Duan Kailiang became vigilant.

"Why do you ask this?"

Seeing this, Huang Sen waved his hand again and again and explained: "I don't mean anything else, if you want to operate for Nexus Tetralogy, I'm afraid ordinary catheters will not work for children!"

These remarks made a trace of surprise flash in Duan Kai's bright eyes.

"How do you know we're going to have a surgery?"

Hearing this, Huang Sen said with a smile: "There are only a few surgeries that can use ECMO, and it is a child, except for the tetralogy of the law, I can't think of anything else!"

With that, Huang Sen turned his head and took out another set of pipes from the car.

"This is a special material for children, just this set, let Liu Dongfang use it carefully!"

Huang Sen's attitude was sincere, his language was sincere, and although he had a bad face, Duan Kailiang still instinctively took the material.

Inside is a disposable circulation line that connects the instrument at one end and the child's blood vessels at the other.

Duan Kailiang held it in his hand and felt heavy.

"By the way, such a set of children's pipes is worth the price of a car, don't make a mistake!"

With Huang Sen's reminder again, this time Duan Kailiang was speechless in shock.

Although he knows that it will be very expensive to start ECMO once!

But when he held it in his hand, he realized that this thing was more expensive than he imagined!

When Huang Sen saw him like this, he already knew that the latter had not been exposed to ECMO at all!

Otherwise, you won't be overwhelmed just by hearing the price!

"The ability of one person to start using ECMO is definitely not enough!"

"If you can, let me come along!"

"It's safer!"

Don't look at Huang Sen's usual days, but once it comes to the interests of the patients themselves, it is still more reliable!

In the face of his proposal, Duan Kailiang was also a little shaken!

After all, Director Liu's surgery is about to begin!

Linlin has also entered the state of anesthesia.

Now!

There is no room for error!

"Come with me!"

After weighing the pros and cons, Duan Kailiang took Huang Sen with him and rushed to the operating room!

......

"Director Liu, ECG monitoring has been started, and the ventilator parameters have been set!"

"When will the surgery begin?"

As the anesthesia deepened, the nurse had already attached various lead wires to Linlin's body.

Tiny wires are interspersed with various parts of Linlin's body.

With each beat of the monitor, the telecommunications converge to present the data in front of everyone's eyes.

"Heart rate 88 beats per minute!"

"Breathe 15 breaths per minute!"

"Blood pressure 96/55mmHg, oxygen saturation 99!"

"Vital signs are stable!"

With the values accurately recorded by the nurse on the surgical order, everything is ready to go!

"What about ECMO?"

Liu Dongfang was wearing a surgical gown, with his hands crossed and placed on his abdomen.

He glanced at the time and frowned slightly.

Seeing Liu Dongfang's inquiry, the roving nurse immediately said: "Director, the instrument is being disinfected next door, and it is estimated that it will be pushed in a while!"

"Good!"

Liu Dongfang nodded, and a fine light flashed in his eyes.

"The operation has officially begun!"

"Yes!"

As soon as the words fell, everyone present spoke in unison!

"Time: 10 a.m."

"Start recording!"

“00：01！”

“00：02！”

With the operating room, the wall watch on the dark green wall starts to kick in!

There was a trace of irrepressible excitement and excitement in everyone's eyes!

After all!

The first quadruple surgery under ECMO in the hospital will start under their witness!

This kind of feeling can only be felt in the operation of an external specialist!

But now!

They can actually experience this excitement in this hospital, and an inexplicable sense of pride arises spontaneously!

Seeing that they were all full of energy, Liu Dongfang also had a smile on the corner of his mouth.

Although the smile was fleeting, it was imperceptible through the heavy mask.

But the firm gaze, revealing incomparable self-confidence, gives people a sense of stability and stability!

"Vecuronium bromide is pumped intravenously to keep the patient in a state of continuous muscle relaxation!"

"Yes!"

As the drug began to take effect, Liu Dongfang said again.

"The patient is an eight-year-old girl, with a height of 120cm, a weight of 20 kg, a BMI index of 13.9, which is less than the normal low value of 18.5, and her physique is thin!"

"The diameter of the common catheter is too thick, which is easy to cause blood vessel tearing, prepare a 10F femoral vein cannula to reduce the risk of surgery!"

"Good!"

The instrument nurse had already handed over the catheter that had been prepared for a long time.

With the completion of iodophor disinfection on the surface, Liu Dongfang touched the groin with one hand and felt the fluctuation from the femoral artery.

A one-inch-long metal puncture needle was then removed and moved inward by another 0.5 centimeters at the most pronounced area.

And there, that is the ultimate goal of his catheterization this time!

Femoral vein puncture site!
