Chapter 90 90. A Strong Mother

In the next few days, except for the night shift, several people stayed in this small operating room.

Gao Feng, Cheng Song, and Hu Jiaran's injection skills have advanced by leaps and bounds. Gao Feng feels that it is almost done, and the rest will have to be done with real knives and guns.

"What? The mouse is half dead?!" Hu Jiaran said in surprise.

Qi Nannan looked embarrassed, "It was fine yesterday, but I don't know what happened today, more than 20 people died."

"It's not an infectious disease, is it?" Cheng Song looked worried.

"It's nonsense, and I didn't take it out, where did the infectious disease come from?" Gao Feng was also a little puzzled, and the few people had undergone a simple disinfection every time they came in, and they were all wearing isolation gowns.

Li Youliang hurriedly called the people from the manufacturer, and the guy who delivered the goods last time came very quickly.

"Too many feeds, these are all strangled to death, and there are many needle holes in these bodies, were they stabbed to death by you?" The young man picked it up and observed it for a long time.

Hu Jiaran was speechless, "Qi Nannan, can you have some snacks, can you eat the same as you when you are a mouse?"

"Idiot!" Cheng Song uttered a second blow to Qi Nannan.

Gao Feng breathed a sigh of relief, then there is no problem, just now he was very nervous, if he made a mistake at the beginning, it would be a fatal blow to their new team.

Tomorrow, the manufacturer will send 200 mice. Li Youliang discussed with Gao Feng.They are going to start the injection tomorrow, and the soluble antigen has already been prepared.

"The biggest problem we have right now is that we don't have any experience. I think the sooner the experiment starts, the better." Gao Feng called everyone together, "We can solve problems if we find problems during the process."

"It's fine if the project can be completed completely, it doesn't matter if the result is not achieved." Li Youliang told Gao Feng specifically, "It's just for practice for the first time."

Li Youliang was telling the truth. Director Shen and Director Zhao both noticed Gao Feng's project. They were just Tu Yile, and they never thought that the project would be transformed into results in the end.

"Then I'm relieved. I was worried that I wouldn't be able to get things out and make business deals." Gao Feng took a reassurance, "But we can't underestimate ourselves." He said.

"Nan Nan, what are you doing after work in the afternoon?" The roommates were a little surprised. In the past, this little chubby girl would lie on the bed after work and watch dramas.

"Raise rats." Qi Nannan yawned. These little things have made her mentally exhausted recently, especially when she went there today and found that almost half of them were dead, she was almost scared to death.

"What kind of mice?"

"It's a white mouse." Qi Nannan took out his mobile phone and showed them, "There are two teachers who are doing experiments and asked me to help."

"Just keep mice?"

"Don't you need to do anything else?"

The roommates asked questions one after another.

"Keeping a mouse will kill me, and I don't know how to talk about other things." Qi Nannan is a self-aware person, and he doesn't like to use his brain.

"Do you want to send money?" A roommate was very concerned about this.

"Currently, I'm generating electricity for love, but if it produces results, it should be distributed." Qi Nannan was not very sure.

"It's just how much money you can send, Nan Nan, you've lost weight, let's see if you're fat." The other little girl spoke bluntly.

I thank you, Qi Nannan thought.

Just after checking the room in the morning, Gao Feng received a call from Dr. Ma Liang.

"Are you busy? There is a patient who wants to invite you to see it." Ma Liang said, "I just had a chest CT scan, and I can't understand it."

"I'll go now." Gao Feng talked to Dong Qianqian, and then took Zhang Tianci to the emergency department.

The female patient, 32 years old, has repeatedly experienced symptoms of chest tightness and fatigue after giving birth in the past year. 1 days ago, the symptoms aggravated after being exposed to cold at night, and she had obvious dyspnea. She was taken to the emergency department by 3 ambulance half an hour ago.

"What is this? Could it be a space occupation?" Ma Liang opened up the chest CT for Gao Feng to see.

Gao Feng looked at it carefully for a long time, "It looks like a pulmonary artery fistula, but she has a lot of fistulas, there must be 5.6."

"Is the patient's oxygen saturation low?"

"Yes!" Ma Liang replied, "Now the mask is inhaling oxygen, 8L/min, but the oxygen saturation is only 87%."

"You should have had a similar situation before, right?" Gao Feng asked the patient.

"It happened several times during pregnancy." The patient's husband replied beside him, "The color Doppler ultrasound said that the heart is not good, and we don't understand what pulmonary hypertension is."

"How many children have you had?"

"Two sons," replied the patient.

Gao Feng admired this patient from the bottom of his heart. In this situation, he was able to give birth to two children smoothly. The patient's strength was a bit outrageous.

"Why didn't you have a chest CT at that time?" Zhang Tianci was a little puzzled.

"Are you stupid? She is pregnant with a child, who will let her have a CT scan." Hu Jiaran and Zhang Tianci are also very familiar.

"Give her this to the interventional department." Gao Feng suggested that these fistulas must be blocked, otherwise the blood from the pulmonary artery will flow to other arteries or veins through the fistulas.Patients will definitely have dyspnea, cyanosis, chest tightness, hemoptysis, fatigue and other symptoms in the later stage.

"The cost is estimated to be quite a lot." Gao Feng reminded the patient's husband that he might not be able to afford without 10 yuan.

"That's okay." The other party's expression relaxed, "I was scared to death just now, and I'm planning to sell the house."

Everyone.

After work in the evening, Gao Feng rushed to the scientific research building.The mice have already been delivered, Qi Nannan took half a day off in the afternoon, Li Youliang and the guy from the factory have already settled the mice.

"Let's eat first." In fact, everyone was not in the mood to eat, so Gao Feng dragged them to a nearby restaurant to eat.

Today is the beginning of the experiment, and everyone is very dignified. Gao Feng and Qi Nannan selected the healthy mice, and 162 of them were eliminated.

Qi Nannan was in charge of the elimination. She fixed the back of the mouse's head with her thumb and index finger, pinched the tail of the mouse with her right hand, and pulled it back and upwards forcefully. When she heard the rat's neck rubbing sound, the cervical spine was dislocated, the spinal cord was broken, and the mouse died instantly.

It's called a cervical dislocation, and every medical student knows it.

Gao Feng, Hu Jiaran, and Cheng Song were in charge of the next work. After the mice were fixed, a needle was inserted from the outside of the lower abdomen, and the antigen and Freund's incomplete adjuvant were injected.

Soluble antigens have weak immunogenicity, and generally adjuvants are added, and the antigen and adjuvant are also required to be mixed together in equal volumes and ground into a water-in-oil chylus.

Each mouse was injected with about 1.5ml. The three of them were a little slow at first, but they became relatively proficient later on. Hu Jiaran was the fastest.

This still dealt a certain blow to Gao Feng. His mental strength is far beyond ordinary people, and his physique is also so strong. It is reasonable.
But it just didn't make sense, Hu Jiaran not only did it quickly, but his technique was also very standard, it was completely a textbook-level operation.

"You are so awesome." Cheng Song lay down straight, he no longer pursued speed, and tried to be more standard.

"Jiaran will become an excellent scientific research migrant worker in the future." Li Youliang said to Gao Feng, "It needs to be trained well."
