Under the cover of a sterile cloth, the field of vision appears a little dim.

But this is enough for Zhang Tianyang to find what he wants.

His gaze was fixed on the patient's forehead.

The endotracheal cannula extending from the patient's mouth has a noticeable bend there!

The degree of bending does not seem to be completely blocked, but white spider web-like creases have already appeared on the transparent tracheal cannula.

The mist condensed into droplets, clinging to a small section of the tube wall on either side of the crease, and trembling rapidly with the rate of breathing.

It is enough to show what kind of aggrieved state the patient is in.

Zhang Tianyang has reason to believe that this bend is gradually aggravated.

This is because the patient's heart rate changes over a long period of time.

Seeing this tube, which was bent by nearly 80%, combined with the patient's heart rate change pattern, he could even imagine the process of the tube gradually compressed, the breathing passage gradually compressed, and the breathing gradually became difficult.

If the tube had been folded like this at the beginning, the patient would have ggled a long time ago!

The dead knot that he couldn't figure out in his mind was sorted out in an instant, and in a thousandth of a second, Zhang Tianyang quickly stretched out his hand-

Straighten that damn tracheal cannula!

Then, he rushed to the computer belonging to the anesthesiologist and increased the oxygen flow to the patient by two bars.

"What are you doing!"

Pan, who was limping, was the fastest one.

"The tracheal cannula is broken. ”

Zhang Tianyang gently lifted the heavy sterile green cloth and pinched the freshly bent part of the tracheal cannula for Pan to see.

There were still white reticulated cracks left in the bends, and there were still droplets of adherent water that had not had time to rise.

Pan was a little stunned, "It's really!"

The ventilator pumped out the air step by step, and the oxygen flow rate was deliberately increased by Zhang Tianyang and dispersed into the patient's body along the re-opened pipe.

"Didi, Didi"

Visible to the naked eye, the heart rate, which had just been rising, suddenly stopped increasing at a pace that continued to increase.

Then, there was a gentle decline.

On the computer screen dedicated to anesthesiologists, the folded line belonging to the heart rate rises together, like a mountain, and finally slowly stabilizes.

"Heart rate, back to 76 beats per minute!"

Senior Brother Meng stared at the monitor and quickly reported the data.

"Whew-"

The female anesthesiologist next door who was pulled by Sun Yu breathed a sigh of relief, and then left with a relaxed body.

The nurses in the audience, who were ready for battle, also breathed a sigh of relief and turned to focus on the instrument nurses.

"Did you violate the principle of sterility when you first ran out?"

The anesthesia intern exhaled a breath of turbid air tremblingly, and suddenly felt a little soft under his feet and a little black in front of his eyes.

He quickly leaned against the wall next to him, and then slowly crouched down.

Some want to cry, some want to laugh.

"Scared the hell out of me!"

He almost thought that he had only been in the anesthesiology department for three days, and he was going to be persuaded to retire because of a major accident!

......

Crises come and go quickly.

The patient's heart rate spiked to nearly 100 within a minute and then dropped back within two minutes.

Finally, it stabilized at 70-80 beats per minute.

The foreign aid returned to their respective homes, and the instrument nurse also returned to the instrument table.

The chief director picked up the operating lever, and Senior Brother Meng took out the laparoscope.

After Zhang Tianyang "sacrificed his sterile self and saved the life of a patient who was about to suffocate to death", the operation was finally continued.

Of course, the position near the patient's head was well protected by the anesthesia intern with a frightened face, and the sterile cloth was also lifted up by him to fix a small corner so that the inside could be observed at any time.

He didn't want to do it again!

Anesthesiologist Pan stared at Zhang Tianyang in amazement for a long time, and then twisted his ass and began to record something in front of the computer.

Zhang Tianyang's attention was on his round stool.

There is a round stool next to it, and he doesn't even sit on it?

Still twisting your ass?

emmmmmm

I feel like I've accidentally found something interesting~

......

"Student Zhang......"

When Zhang Tianyang pestle was removing his "contaminated" surgical gown next to the trash can, Sun Yu quietly came over.

Her breath was a little gasping, and the fright and running just now left fine sweat on her forehead.

She turned her head to look at the crowd around her, who didn't mean to ask.

Some hesitation, some embarrassment, but in the end I asked in a low voice.

"How do you know that the tube of the endotracheal tube is broken......?

The problem is in the corner where he can't see out of sight, how did Zhang Tianyang accurately judge it, and then fight the consequences of contaminating the surgical gown to pick up the sterile cloth there?

"Yes, Xiao Zhang, you can talk about it. ”

The chief director on the operating table not far away heard the movement here, but encouraged him.

"Other people talk to each other during surgery, I don't like to talk, but I can do it while listening. Tell me about your judgment?"

Senior Brother Meng instantly turned his head to look at Zhang Tianyang, and his eyes were instantly full of curiosity.

Just now he tragically wrapped himself in, and countless possibilities were messed up in his mind like a mess of yarn that could not be untied.

But how did Zhang Tianyang find the thread?

"Xiao Meng, my vision is crooked!"

The chief snorted coldly, and finally called his soul back.

But obviously, Senior Brother Meng's afterglow is still floating towards Zhang Tianyang.

The instrument nurse looked down at the table full of instruments, apparently indifferent.

But Zhang Tianyang, who has a keen sense of hearing, noticed that the sound of her breathing suddenly disappeared.

It's clearly holding your breath, and your attention is all on yourself!

I accidentally became the focus again......

"I ...... at the time"

Zhang Tianyang briefly recounted his first two judgments and gave the reasons for rejecting them.

"So, in the end, I think the reason for the patient's increased heart rate is the lack of oxygen!"

"The proof is the oxygen saturation on the monitor, although it was still 100 at the beginning, but when the heart rate reaches 95, the saturation jumps to 99, and when the heart rate reaches 96, the saturation jumps to 98, and there is a downward trend. ”

Senior Brother Meng hugged the laparoscope and nodded busily.

He noticed this, but he still couldn't think of it.

"There are many possible causes of hypoxia, why ......"

Sun Yu picked it up next to him, "Why can you be sure that it's this, and not the cause such as pneumoperitoneal sequelae?"

The gas that makes the pneumoperitoneum happens to be carbon dioxide, and it is indeed related to the lack of oxygen.

"I also suspected that it was an artificial pneumoperitoneum. ”

Zhang Tianyang paused.

"Among the complications of artificial pneumoperitoneum, there is indeed hypercapnia, and there will also be symptoms of increased heart rate and decreased blood oxygen saturation.

However, this complication is usually caused by the long operation time and high pneumoperitoneum pressure, which is not in line with our situation.

And this kind of thing, there must be a process of change, and the situation just now is progressing too quickly.

It's like ......"

"Like the airway is blocked?"

Zhang Tianyang nodded at Sun Yu with a smile, "Congratulations, you have learned to answer." ”

"Of course, there is one more piece of evidence. ”

He pointed to the ventilator's slightly lit screen.

"There are a few values here, and they have changed just now. If the anesthesiologist is here, he should be the first to realize that the endotracheal tube is bent. ”

Next to him, the anesthesiologist Pan, who was pouting his skin in place, nodded approvingly.

"It's not unusual, but it's probably the first time I've encountered it as an intern. ”

The anesthesia intern bowed his head beside him, and his head drooped even more when he heard the words.

"I see. ”

On the operating table, Senior Brother Meng was thoughtful.

So Senior Brother Zhang was able to find out the wrong thing so quickly, is it because he is even proficient in the field of anesthesiology medicine?

In other words, do you want to try to dabble in anesthesiology as well?

He looked at Anesthesiologist Pan, who was standing strangely next to him.

I always feel that this anesthesia teacher is a little unlucky......

The director continued the operation in silence, skillfully separating various tissues, and sometimes cutting with an electric knife.

After a moment of silence, he suddenly burst into words.

"Xiao Zhang, let me ask you. ”

"Huh?"

"Do you think gastroenterology is better, or is it better for us to urology?"

Zhang Tianyang instantly cheered up.

The word "we" is used.

This question is a proposition!
