There was no need for positioning at all. Dark red blood was slowly flowing out of Xiao Chenguang's cannula.

The skin around the puncture was intact, and there was no subcutaneous emphysema.

Director Xiao was really amazing.

The anesthesia and the inspection were stunned.

You should know that patients who have already gone into shock not only have very poor blood vessel elasticity.

Sometimes, it is even difficult to tell whether the blood vessels on the skin are blood vessels or blue veins.

When encountering such patients, it is often difficult to get a needle. If there is edema, it is really possible that even if the waist is broken, there is no chance of getting a needle.

However, Xiao Chenguang just glanced at it lightly, and his technique was so skillful that they all felt that such an operation seemed not worth mentioning at all.

But is this really the case?

The anesthesia suddenly looked at the patient who was standing sideways with his head down and his feet high, and the surprise in his eyes increased instead of decreasing.

The patient's position was definitely not specially placed for puncture.

Even this special position changed the original direction of the blood vessels.

But even so, Xiao Chenguang still hit the nail on the head, and he continued to insert the guide wire into the needle cavity.

He pressed the wire with his left hand, pulled out the puncture needle with his right hand, took out the intravenous catheter in the kit, and continued to extend it along the wire.

During this period, he did not use any auxiliary tools, and his hand kept pushing the guide wire into the blood vessel.

Seeing this scene, everyone in the operating room did not dare to speak easily.

Especially Xiao Chenguang's focused eyes, which were vaguely revealing a hint of frightening momentum.

This made Sun Chengwu, who was standing aside, suddenly have an illusion.

It seemed that the person on the stage was a respected surgical expert he had studied with in his early years.

That concentration and unquestionable posture were like being carved out of a mold.

At this moment, Xiao Chenguang's guide wire had reached the key fork.

This is the only way from the clavicular vein to the superior vena cava. As long as the guide wire can pass smoothly, it can reach the final destination, the heart.

In fact, operations like this are performed in the catheter intervention room in the future, with professional imaging equipment, and there is no need to cross the river by feeling the stones.

Even if there is no intervention room, the artery and vein can be distinguished by the Doppler effect of B-ultrasound and orderly operations can be performed.

But at this time, because the situation is urgent and the hospital has no funds to build an intervention room, everything now depends on Xiao Chenguang's rich clinical experience.

Although it is a bit difficult, the operation experience of the previous life is deeply engraved in Xiao Chenguang's mind.

This is just like the family members who were treated for anaphylactic shock in the general surgery ward just now, and there is no need to think about it carefully.

Everything depends on the operation instinct and can be easily solved.

"Anesthesia, pay attention to the waveform changes of the ECG monitoring in the patient's ICU."

"Tell me immediately when the patient has ventricular tachycardia."

Faced with Xiao Chenguang's request, anesthesia responded immediately.

"Director Xiao, don't worry, I never took my eyes off the monitor."

Although he didn't know why Xiao Chenguang had such a request, as the anesthesiologist of this operation, he had the obligation and responsibility to report the patient's condition to the surgeon at any time.

"Okay."

With the help of anesthesia, Xiao Chenguang no longer paid attention to the values ​​on the monitor. At this moment, he concentrated on the hair-thin guidewire in his hand and began to operate with full concentration.

The surrounding sounds were quiet, as if the whole world was left with only Xiao Chenguang and the operation in front of him.

The touch in his hand became more and more obvious.

Even in his mind, the entire blood vessel direction has been formed into a movable map.

He only needs to follow the guidance of the map to find any place he wants to find.

The guidewire moved slightly in his hand, changing the angle, and every time it touched the blood vessel wall, it gave him a clearer direction.

At this time, Xiao Chenguang's movement suddenly stopped.

The unique touch made Xiao Chenguang know that the guidewire had reached the most critical position.

Then he began to insert the deep venous catheter.

The anesthesiologist who had been paying attention to his operation looked at the monitor sideways.

The heart rhythm was still normal QRS wave, although the T wave was a little flat, but this was related to the patient's low blood pressure and insufficient return of blood to the heart.

No matter how you look at it, it doesn't look like the waveform of ventricular tachycardia that Xiao Chenguang just said.

But at this time, Xiao Chenguang had already started to pull out the guidewire, as if the operation had been completed.

What is he doing?

The anesthesiologist was a little anxious. Could it be that because the operation was too difficult, Xiao Chenguang couldn't find the position and was ready to give up.

That's right.

Originally, blind puncture is a matter of luck.

No matter how strong Xiao Chenguang's ability and operation are, if he wants to find the position accurately from the invisible blood vessels, he will have to wait for a long time.Right atrium is also an impossible thing.

It seems that this time, everyone will fall in this operation.

Anesthesia showed a bitter smile.

In his mind, he was already thinking about whether his anesthesia record was written in accordance with the rules, whether the conversation with the family members was in place, and whether the angry family members would go to court because of some negligence.

"Director Xiao..."

Just when Anesthesia was about to ask what to do next, the originally calm heart rhythm on the monitor suddenly seemed to be convulsed.

The regular QRS wave group was instantly replaced by a large wave line like a tide.

"The patient... really has ventricular tachycardia!"

Anesthesia stared at everything in front of him in disbelief.

How did Xiao Chenguang do it?

He could actually predict in advance that the patient would have ventricular tachycardia.

Could it be that he just paused because he had already explored the right atrium?

Just when Anesthesia was confused, Xiao Chenguang, who had already pulled out the guidewire, immediately found a 30ml empty needle.

He pulled out the needle, put it on the end of the deep vein catheter, and pulled it hard. Nearly 20ml of impurities mixed with black blood and foam were pulled out.

Looking at the tube of blood foam in Xiao Chenguang's hand, everyone was stunned.

"Director Xiao, is this the air of embolism?"

Although they already had a hunch in their hearts, they still couldn't help asking.

"That's right."

Xiao Chenguang said lightly.

After getting his affirmation, everyone's throat surged and their expressions were astonished.

The anesthesiologist at the bedside seemed to have thought of something, and his expression became more and more excited.

"Director Xiao, your technology is too amazing. The ventricular tachycardia that the patient just had was because your guidewire stimulated the right atrium."

After thinking about all this, Anesthesia finally understood why Xiao Chenguang asked him to pay attention to the waveform of the heart rate on the monitor in advance.

It turned out that Xiao Chenguang had anticipated all this.

No wonder when the patient had air embolism and everyone was at a loss, only Xiao Chenguang remained calm.

Such rescue, in the eyes of ordinary people, is like a terror, but for him, it is a piece of cake.

"You can check the patient's precordial area now to see if there is any sound of blister rupture."

Xiao Chenguang smiled and looked at the still shocked Anesthesia. His warm voice was like a spring breeze, giving people a sense of solidity and warmth.
