"This?!"

Duan Kailiang was confused for a while!

Without blood return, how could this be a successful puncture!

"The needle is inserted 0.5cm medial to the femoral artery, and the puncture depth is 4cm according to the patient's cortical layer, and the needle is directly inserted!"

At this time, Liu Dongfang had already finished installing the pipeline and came to Duan Kailiang's side!

His eyes were like torches, he glanced at the patient's groin, and directly analyzed the results!

"Really?!"

Duan Kailiang was shocked in his heart, although he knew that Liu Dongfang's medical skills were good!

But like this, you can see through the direction and structure of the patient's blood vessels at a glance!

You can even tell how deep the needle is inserted!

Could it be that his eyes are made of B-ultrasound and can see everything?!

"Try it!"

Liu Dongfang smiled but did not speak.

This self-confidence, even Duan Kailiang himself, also feels it!

He positioned himself with his left hand, held the needle in his right hand, and according to Liu Dongfang's retelling just now, he directly inserted the needle!

Sure enough!

No blood return at all!

You can't even feel the touch of your fingertips!

Is 4cm really good?!

Duan Kailiang was puzzled, but he still followed Liu Dongfang's instructions and moved forward 4cm!

"Alright, let's unsheath it!"

After that, Liu Dongfang turned his head directly and pushed the blood filtration machine on the side to the bed!

So confident?!

Even the little nurse who was waiting for instructions on the side was curious.

After all, this kind of femoral vein puncture is different from the previous puncture!

The femoral vein, along with the femoral artery, is the most important blood vessel in the body to transport blood!

It has a long diameter, good elasticity, and is the size of a thumb!

Crucially, it has a blood flow rate of up to 130 per second!

This is equivalent to a car driving on the highway at top speed!

Therefore, a slight carelessness may cause subcutaneous hematoma and even massive bleeding in the body!

"I pulled it out!"

Duan Kailiang deliberately shouted!

But in the face of the indifferent Liu Dongfang, Duan Kailiang sighed secretly and pulled out the guide wire!

With the insertion of the tube diameter, Duan Kailiang couldn't wait to start withdrawing with the syringe!

At this moment, a slightly black blood flowed out of the lumen!

Venous blood!

Duan Kailiang recognized the nature of blood at a glance!

"It's really in the veins!" exclaimed the nurse next to her.

With just one glance, you can pinpoint the location of the blood vessels!

This kind of technique is unheard of!

"How did you do that?!"

Duan Kailiang's eyes flashed with a gleam, for Liu Dongfang's medical skills, he had reached the point of admiration to the extreme!

"Do more, you can too!"

Liu Dongfang smiled, and in the face of their adoring gaze, he was a little embarrassed!

After all, it's the basics!

There's nothing to brag about!

However, everyone was still in shock, and they couldn't come back to their senses for a long time!

Although I can't bear to interrupt them, the patient needs further treatment!

Liu Dongfang opened his mouth and said: "Since the catheterization is successful, hurry up and do CRRT treatment!"

"Good!"

Duan Kailiang, who had just woken up from a dream, knew that there was still work to be done now, and immediately calmed down!

"Director Liu, blood filtration mode?"

Liu Dongfang thought about it for a moment and replied: "First continuous static - venous blood filtration!"

"Good!"

Duan Kailiang turned on the machine and turned to CVVH mode!

Seeing that the blood filtration machine began to operate, Liu Dongfang said again.

"Blood flow rate: 120 ml/min!"

"Front replacement: 2000 ml/h!"

"Dehydration: 200 ml/h and adjust at any time according to the patient's urine output!"

"Sodium citrate: 220 ml/h, adjust at any time according to blood gas analysis!"

As the doctor's orders were issued, Duan Kailiang quickly adjusted the buttons on the blood filter machine!

As the blood pump turned on, a bright red streaked out of the patient's body!

The blood is broken down and filtered in the machine and finally re-enters the patient's body!

The whole continuous process is called hemofiltration!

That is, commonly known as the exchange of blood!

After about half an hour, Liu Dongfang suddenly showed a smile.

"It's time for him to wake up!"

"Really?"

Hearing this, Duan Kailiang was shocked and said, "It's only been a long time, isn't it a little too fast!"

As soon as the words fell, I saw Zhang Lin lying on the hospital bed, slowly opening his eyes.

Liu Dongfang didn't have anything to do with this change, but Duan Kailiang on the side was speechless in shock!

Blood filtration has such a miraculous effect!

It was only half an hour before and after, and the patient on the verge of death was pulled back!

It's amazing, too!

Seeing this, the little nurse on the side quipped: "It's not because the parameters set by Director Liu have worked!"

"Otherwise, how could a single blood filter machine cure his disease!"

"Yes, yes, I just ignored the most critical factor!" Duan Kailiang said thoughtfully.

Seeing that they take turns complimenting, it doesn't seem to mean the end!

Liu Dongfang couldn't stand this posture, and scolded with a smile: "Okay, go on duty, I'll just watch here!"

"Don't have a sick number at that time, you can't see anyone, it's time to complain about us again!"

As soon as these words came out, the little nurse was immediately frightened and hurriedly stretched out her finger and put it on her lips!

Hush!

"Director, don't you know that we are evil!"

"You can't just say that!"

Before the words fell, I only heard a noisy sound outside the emergency department!

Seeing the nurse leave, Liu Dongfang's resentful little eyes made Liu Dongfang shudder!

"It seems that it is better to say less in the future!"

Liu Dongfang, who had made up his mind, came to Zhang Lin's side and asked, "How do you feel now?"

If you are familiar with it, Zhang Lin, who is still a little confused, suddenly opens his eyes!

"It's you?!"

"Where am I?!"

"What are you going to do to me?!"

Seeing that the enemy was in front of him, but he had no strength at all!

This made Zhang Lin feel a sense of fear of letting the flesh of the mermaids!

"The last time I told you, don't eat supplements indiscriminately, I just don't listen!"

"If it hadn't been for the timely rescue this time, you would have confessed a long time ago!"

Liu Dongfang's reprimand made Zhang Lin look stunned, and then he realized that he was in the hospital!

"Are you a doctor?" Zhang Lin said tentatively.

Combined with the confrontation at the last bidding meeting, Liu Dongfang's words were fulfilled one by one!

This made Zhang Lin feel more and more that the person in front of him was not ordinary!

Sure enough!

As Liu Dongfang nodded to confirm, Zhang Lin actually had a feeling of the rest of his life!

"Thank you!"

"From now on, I, Zhang Lin, owe you a life!"

"You can always come and pick it up if you want!"

In the face of his former enemy, he has become a lifesaver at this moment!

This contrast makes Zhang Lin, who practices martial arts for a living, a little overwhelmed!

Seeing Zhang Lin's solemn face, the corners of Liu Dongfang's mouth rose slightly, and he said with a smile: "I'm a doctor, not the king of Hades, what's the use of asking for your life!"

"That's not good, I owe your life, I must pay it back!" Zhang Linwen said angrily.

Seeing Zhang Lin's serious expression and resolute attitude, he obviously looked like he was admitting death, which made Liu Dongfang a little helpless!

"Then you treat the disease first, and when you need it, I will naturally take it!"
