Physiological processes in human bodies have feedback mechanisms, which are divided into two categories: positive feedback and negative feedback.

For example, eating is a negative feedback mechanism.

When you eat a certain amount, the stomach will give the brain a negative feedback message that the stomach is full, and then the brain will feel full and naturally command your mouth not to eat anymore.

However, this kind of feedback from the stomach is slow, so eating quickly makes you prone to eating too much, and you will get fat over time.

So it is true that you eat quickly and get fat easily. As the saying goes, it is also true that you eat 80% full. Because the feedback will be in place after a while, and the feeling of fullness will come.

The process of emptying such as urination and defecation, vomiting and other ejaculation is a positive feedback mechanism.

Once the whole process starts, the bladder, rectum, and stomach will give the brain a positive feedback message that "it's so comfortable, continue, don't stop."

This feedback stimulation will create a comfortable feeling until all the contents are emptied.

Although boys have learned what positive feedback is in books, they have never seen the power of this mechanism.

The patient is aroused by vomiting reflex, and with the decompression of the gastric tube, the entire fermented feces accumulated in the gastrointestinal tract will continue to surge outwards, until the body feels that it has been empty.

At the beginning of the second wave of outbreak, he couldn't stand the stench that was far beyond ordinary people, and escaped with the two girls.

"It's said it's difficult..."

Qi Jing couldn't see Shen Xing's embarrassing appearance, so he ran to the debugging room and took out several disposable surgical gowns and threw them at the scene of the incident. Then he called the cleaning lady and cleaned the battlefield as soon as possible after everything was over.

Otherwise, in just a short while, the smell will spread throughout the first floor of the emergency room.

When it comes to the operation of the entire emergency system, it may be a doctor and nurse for the patients. But for medical staff, the most important thing is definitely these cleaning aunts.

They are dealing with various body fluids, blood stains, and semi-solids on weekdays, including disinfection of the inspection area.

Without them, the emergency room may be shut down within one day. If you encounter a few more excessive patients, the time will be shorter.

"Sister Zhao, come quickly, the door is in a hurry."

Sister Zhao was wearing plastic gloves and masks and hats. She stood at the door, holding a mop in her hand: "I vomited with intestinal obstruction? I was still wondering what the smell is, so heavy!"

When the two returned to the scene, the scene was so tragic that only those who were really watching could understand.

If you really want to make a comparison, you will lose a bomb in the feces pumping truck and explode it directly.

However, for Sister Zhao, this situation has been seen a lot, and she doesn't care whether it is dirty or not.

She wore waterproof rain boots, didn't bother to take a lot of it and stepped on it. Then she held the plastic bucket in one hand and put it in front of the patient: "I won't be able to hold this bucket in my hand, you see, vomiting everywhere!"

Shen Xing had long been stupid, just scold him. It would be a blessing to have someone to help him, but he still has so much to care about.

However, Sister Zhao's suggestion made the patient see clearly what he vomited. Suddenly, the visual and olfactory stimulation further aggravated his vomiting reflex, and the third wave that was originally ranked behind actually came out in advance.

"If you guys do anything more, I won't do it!"

"Isn't this an accident?"

"Let's be careful next time..."

After the matter came to an end, Sister Zhao called the good sisters on the second and third floors to help. She laid paper and mopped the floor. Finally, she sprinkled two bottles of disinfectant water on the entire emergency area before finally covering the smell off.

Qi Jing sat in the clinic, looking at the medical records in his hand, and couldn't get any interest.

The symptoms of these patients who came to the evening were very typical, and there was no problem. They were solved by Yan Dingfei and Qu Yi in a few strokes.

The three students did not come again, probably already had a serious shadow. If someone could come back without running or taking a shower, Qi Jing really wanted to take her with her to try her best.

After all, Hu Dongsheng is far from enough.

He sat quietly in the chair until he got off work.

In order to spend time, we also chatted with Zishan and Hu Dongsheng for a while.

Lu Zishan asked for leave during the day and is now making up for the case, so she greeted each other and said goodbye after a few words.

Hu Dongsheng just got up and had a meal, and was about to read through books and start a new nightlife. He never expected that Qi Jing would come to him on his own initiative.

【Tomorrow, be my younger brother】

Looking at this message, he carefully studied the definition of the word "little brother" for a while, and then replied.

[Emergency Department? What did Director Wang say there? I was almost caught last time.]

【Just come just to come, I'll do it for the old man】

Hu Dongsheng has long been tired of boring books. He can earn money if he can enter the clinical clinic half a month earlier than others. It is definitely a fake to say that he is not moved.

【When do I need to arrive?】

【Tomorrow I will work early at 7 o'clock, why should I go to work earlier than my elder brother?】

When Hu Dongsheng saw the words, he looked like Qi Jing was sitting on the chair and smiling. Naturally, he had the expression on his face that he was hiding and trying to kill the other party.

【Okay, I'll arrive before 7 o'clock】

He just got up now and it was almost time to sleep for three hours by reading a book.

However, Qi Jing seemed not very satisfied with this time.

[You are living in the dormitory building of the hospital, and the emergency room is not closed. Are you embarrassed to come so late?]

【What time should I do?】

[When I am not seeing a case, you have to get familiar with the patient first and remember at least half of the patients' main complaints, symptoms, diagnosis and treatment]

[So many requirements... One hour is not enough]

[As long as you can do these things, I have no objection to what time you want]

Hu Dongsheng gritted his teeth and had the urge to rush to the emergency room now. But if you think about it, you should forget it. The body is the most important capital, and over-consuming is not good.

【I understand, it will be at five o'clock】

......

After arranging Hu Dongsheng, Qi Jing came to the gate of the emergency room and took a breath of fresh air: "It's finally going to start. Let's go back and have a good rest. Tomorrow he has to make the magazine window well."

After a long stretch, an ambulance sounded from a distance. The sound came from far to near. When I entered the hospital gate, I turned left and opened the slope at the door of the emergency room in a short while.

Qi Jing was bored for an afternoon and stood aside to see what patient was loading on the car.

As soon as the car stopped, a doctor following the car jumped off the back door and held the emergency list: "The patient is 53, a man, vomiting a lot of blood, probably about one liter, and now his blood pressure is 88/56..."

The person who was treated was Wu Tongshan, who had just come to take over, felt it was difficult to see the patient's anemia. In addition, there was a large area of ​​bright red blood on the edge of the stretcher's bed, which obviously had just vomited blood.

Major bleeding in the upper gastrointestinal tract is often dangerous and it is very difficult to stop bleeding. Patients who have already had anemia are prone to have severe bleeding and direct shock.

It will be really difficult to save it.

Qi Jing leaned up curiously and looked at the patient. His face was pale and thin, and he was not energetic, but he gave him a very familiar feeling.

emmm.........!

He suddenly remembered the gout patient who asked him to prescribe medicine at noon. Although he had only met for less than five minutes, he still left some impression on Qi Jing.

Ying Taiqing, prednisone, upper gastrointestinal bleeding...

Qi Jing had a very bad premonition in his mind.
