"Boss Zheng, are you sure?" Zhao Yunlong asked in a low voice.

"Try it. I think it should be all right."

In the song of good luck, Lao he began to give medicine and intubation.

Everything went well and there were no unexpected complications. Seeing that the patient's vital signs were stable, director Xu was also relieved. As long as the anesthesia level can pass, it has nothing to do with yourself. As for the rest, naturally thoughtful people worry.

In the case of pulling the board, director Xu thinks it's best not to have surgery. It's none of his business, and he doesn't bother to think more.

"Boss Zheng, what are you doing recently?" Director Xu smiled. The patient was anesthetized and his voice was a little louder.

"This is not the collective poisoning of students in No. 2 middle school at noon. I went to take samples to find the cause of the disease." Zheng Rendao.

"No. 2 middle school... I heard that the food in the student canteen is pretty good."

"Well, I went to have a look. Everything was fine." Zheng Rendao, "it is now suspected that there is a problem with fresh juice, which leads to acute copper poisoning among students."

"..." director Xu was stunned and looked at boss Zheng, who was speechless. Acute copper poisoning is rare. Boss Zheng is really busy day by day. I don't know when he can follow the patient.

"By the way, boss Zheng, didn't you say you had a live operation this afternoon?" Director Xu asked.

"I didn't do it. I'm just busy with food poisoning." Zheng Ren sighed and hoped that the CDC would do the laboratory examination as soon as possible and solve the problem. It's a good thing to carry out the operation live broadcast early. What he cares about mainly lies in the reward given by the system task.

"Copper poisoning, but it's rare. Today, this patient is also rare." Director Xu said with a smile, "boss Zheng, I think I need thoracotomy when I see the film. However, the risk of thoracotomy is also very large, which interferes with your work."

"You're welcome, director Xu. I was already busy when you asked Fang Lin to call. Take the oranges in the fresh juice machine to the CDC for testing. It is estimated that the results will be available in two hours without delay."

Zheng Ren said with a smile.

"Will there be a lot of copper in oranges? How do you get in? Is it fresh or looks better?" Director Xu has some doubts.

"I also don't understand. I haven't heard that copper will help oranges."

"Generally, orange sellers will wax the skin, which makes it look more shiny, but the amount is small." Su Yun said, "but the copper element doesn't help to sell, and I don't want to understand."

Director Xu wanted to say something. His mouth moved slightly, but there was no sound at last.

Zheng Ren understood and said with a smile, "I don't think there should be any mistakes when doctor Chang asked about the medical history. The medical history shows that the students with food poisoning have a common experience - drinking freshly squeezed orange juice."

"Wait and see, the details are not clear." Su Yun twists his mobile phone in his hand and looks at the TV screen of director Li's endoscopic surgery. He doesn't know what he's thinking about.

The operation went well and ended in less than an hour.

Before waking up from general anesthesia, Zheng Ren gave the patient another echocardiography and found that the heart returned to the left a few tenths of a centimeter. The patient's vital signs were stable without any abnormality.

If it were not for the routine CT before the operation to find the problem, if it were not for the solid basic clinical skills of 912 medical staff, they could directly see the heart torsion, I'm afraid the patient would be ignored.

Even many doctors will look at this as a congenital right heart.

"Boss Zheng, where will the patient go next?" Director Xu asked.

"Go to ICU or general ward. The most dangerous time is intubation. After this period, the patient can recover slowly." Zheng Rendao.

After thinking about it, director Li of the liver and gallbladder sent the patient to the ICU. Are you kidding? If a patient with cardiac torsion accidentally stimulates the vagus nerve during reset, what about cardiac arrest.

If you go back to the general ward, do you have to arrange special guardianship?

Zheng Ren didn't care about these things. Seeing that the patient woke up, he smiled and said, "if it's all right, we'll go first."

"OK, I'll contact you when I have something."

When he came to the dressing room, Su Yun asked, "boss, are you sure?"

"Almost. If there is a heart hernia, there will be symptoms long ago. It won't attack again when the heart is slowly reset." Zheng Ren said more definitely.

"Who gives you confidence?" Su Yun asked suspiciously.

"I speak vaguely. You tell me not to talk to you in the tone of explaining the patient's condition. I'm sure I can't. what do you want?" Zheng Rendao.

Su Yun stood up and looked up at the sky.

[they say...]

Zheng Ren answered the phone.

"Nothing? No way."

"Good forest, I know."

After a brief exchange, Zheng Ren hung up the phone, screwed his eyebrows together and pondered carefully.

From the phone, Su Yun already knew what had happened. He was also very confused. According to the medical history asked by Chang Yue, there should be no problem. Is there anything else he didn't take care of?

It's really weird. Su Yun rarely thinks seriously.

But there is really no idea. Zheng Ren straightened things out. Just now director Lin said that there are only some small problems in the various samples collected in the canteen, and has been ordered to make rectification. But small problems refer to things like molds and bacteria, which have nothing to do with copper.

What the hell is going on... Or go to see the students in eye No. 2 middle school? Zheng Ren had such an idea.

Before Zheng Ren made a decision, the mobile phone rang again.

This time it's fan Tianshui.

"Mr. Zheng, someone wants to move the machine." Fan Tianshui's voice was low and his speech was a little urgent.

"Hmm? Moving the machine?" Zheng Ren asked suspiciously that he had no idea. Listening to fan Tianshui, he suddenly remembered that there might be something wrong with the machine.

"Wait, I'll go right away." Zheng Ren said, "are you from the school?"

"It is said that they said they would call the police if they didn't let them move."

"I'll contact Lin Chu and you... Try to delay. By the way, don't hang up and don't hurt people, old fan!" Zheng Ren finished and hung up in a hurry.

This day by day, but really tossed, Zheng Ren sighed.

"There must be a ghost to move the machine at this time!" Su Yun said definitely.

"I think so. There may be a problem somewhere in the juicer." Zheng Ren quickly changed his clothes and straightened out his thinking, "what is the pH value of orange juice?"

"It is generally 3-4. The lower the pH value, the more sour it will be. Freshly squeezed may be concentrated, resulting in further reduction of pH value." Su yundao.

"It's possible! I remember two cases of copper poisoning caused by exposure of copper parts of coke machine and immersion in coke with pH value of about 2." Zheng Ren said, "hurry up, call a car and catch up right away."
