But just for a moment, the heart rate of the experimental body directly returned to zero, which didn't give Zheng Ren a chance to respond at all.

Zheng Ren immediately put down his equipment and began to press his heart. Then he bought an anesthesiologist assistant to help with the rescue.

Do cardiac compression by yourself and instruct the anesthesiologist to inject lidocaine, adrenaline and atropine intravenously.

But it's totally useless. No matter how many drugs are given or how to do extrathoracic cardiac compression, the heart rate of the experimental body just can't return.

Even in the end, Zheng Ren directly cut open and looked directly at the external chest cardiac compression. The patient's heart seemed to have lost its vitality, and there was no independent contraction at all.

After 20 minutes of rescue, Zheng Ren simply gave up. He silently stood beside the experimental body and wondered what had happened, so that a healthy young man would lose his heartbeat in an instant.

Later, he had some ideas, walked out of the system operating room and was ready to click to buy operation training time.

"Boss Zheng, are you tired?" Gu Xiaoran's voice sounded in his ear.

Zheng Ren was very helpless. He sighed.

The patient hasn't come up yet, everything hasn't happened, there are people around, and there's no chance to concentrate. Unless you've been squatting in the system operating room, but it's completely unnecessary now.

Even one second before the patient's heartbeat stops, he can't figure it out. He can go to the system operating room in time.

"No." Zheng Ren left the system space and said softly.

"I saw you walking and suddenly stopped walking. I thought you were not feeling well." Gu Xiaoran stood beside Zheng Ren and said with concern. His hand was next to Zheng Ren's arm. As long as his body shook, he could hold it immediately.

Zheng Ren glanced at Gu Xiaoran's hand, looked at him carefully and smiled, "thank you, Xiaoran. I just feel something in my heart and thinking about things."

"Boss, you won't have hypoglycemia." Su Yun is talking to Lao he shoulder to shoulder in front of him. He hasn't forgotten to listen to the conversation between the boss and Gu Xiaoran behind him.

"No, Su Yun, don't talk nonsense with Lao he. Come and let me ask you something." Zheng Renhe and Su Yun said.

"Huh?" Su Yun was very confused. His boss rarely spoke to himself in this tone.

Is this asking for your own opinion? What happened?

"I've felt something wrong since I saw the patient." Zheng Ren said frankly, "I always think there may be something missing, but after thinking about it several times, I always don't know where the problem is."

"Are you okay?" Su Yun looked at his boss suspiciously. The three-layer mask couldn't stop the kind of disdain on his face.

"Seriously, no kidding." Zheng Rendao.

"Urethra, even if it is torn, the urinary catheter will be fine in the next period of time. You see the patient's spirit, it doesn't seem to have signs of urethral infection." Seeing Zheng Ren's solemn expression, Su Yun also began to try to analyze it.

Lao he didn't even know what the patient was like. He looked confused and couldn't say a word. But on second thought, six hands. When boss Zheng talked to Su Yun, he walked quickly to six hands.

"Xiao Zhou, when will the patient go?" Lao he asked hurriedly after entering the house.

"Lao he, what's up?" The emergency anesthesiologist smiled and said to Lao he.

"What patient is it?" Lao he said with an emphasis.

"Er... A patient with a foreign body in the urethra, I saw an eye film and nine nails in the urethra." The anesthesiologist saw Lao he in a hurry. Although he didn't know what had happened, he immediately told Lao he what he knew.

"The patient's vital signs are stable, there is no pyuria and a little hematuria. It is said that it hurts badly when urinating, so it's choking."

"Is there anything else?"

"No, the tour has gone to pick it up. It's time to come up." The anesthesiologist said, "the patient can still walk, but he has to chop his legs. It doesn't look like there is a problem. Do you know him?"

"I don't know." Lao he recalled what anesthesiologist Xiao Zhou said. There was no pus, there was a little blood, he could walk, and his vital signs were stable. It didn't look like a problem.

Is it because boss Zheng is too nervous and misjudged? The idea had just come to Lao he's mind and was immediately extinguished.

No, will boss Zheng be wrong? It's also possible, he said. There may be a problem, but I don't know what's going on.

Clinicians' weird instincts? Lao he is very serious about looking at the patient first.

"In this operation room, you go to the operating table first." The itinerant nurse had brought the patient back. She pointed to the operating table and said, "can you go up by yourself? If you don't eat hard, I'll move a footstool for you."

"No." The patient said something shyly, then supported the operating table with his hands in a slightly strange position and sat directly on it. He is very vigorous and looks stronger than himself. Lao he has the most basic judgment on the patient through observation.

He took the operation handover form from the touring hand and looked at it. The patient belongs to the emergency department, and the medical record is estimated to have not been written. These are the only available data.

There is no problem with vital signs. With the action of just "jumping" on the operating table, Lao he doesn't think the patient will have a problem.

Boss Zheng must be a little nervous, Lao he thought.

He walked out of the operating room with a smile and saw boss Zheng and Su Yun standing in a position slightly closer to the inside, whispering something.

"Boss Zheng, Brother Yun, I took a look at the patient... Nothing's wrong now." Lao he said with a smile.

"Well, I think it's all right. The boss has to brainstorm." Su Yun also shrugged and stood up helplessly.

"There's a feeling in my heart. I can't tell. I just feel wrong." Zheng Ren shook his head slightly and sighed.

He and Su Yun discussed some possible situations, but there was no constructive idea. Up to now, Zheng Ren still doesn't know why the patient stopped in the operation center.

Just walk in and stop? No one would accept it.

It's really special, Zheng Ren thought to himself.

No way, he had to come to the operating room to see the anesthesiologist bandage the patient with spinal anesthesia. ECG monitoring has been connected, all vital signs are intact, and normal ones can no longer be normal.

"Mr. Yu, how is the patient's hematuria?" Zheng Ren asked.

"Not much. There is a small amount of exudate and no pus. I looked at it and there was only a little blood." President Yu whispered, "boss Zheng, are you coming?"

"No." Zheng Ren turned and sat in the corner on the round stool after the itinerant nurse was busy, squinting his eyes to observe the patient.

Just now, I couldn't tell Su Yun in too much detail. I can only hold it in my heart to predict sudden cardiac arrest in advance. Zheng Ren felt very uncomfortable. If he could say it in advance, Lao he might be able to put forward some opinions for reference.

There must be some "small" problems that I haven't noticed.
