After a while, Wang You put down his sleeves, his eyes were red, and the whole person looked several years old.

"Girl, can you save the three girls with this medicine you have?" He raised his head and looked at Chen Ying beggingly, as if looking at a faint hope.

"That medicine it...... Does it work? He asked again, the corners of his eyes moistened.

However, the hope and eagerness in his eyes were so strong.

Chen Ying looked at him in a daze, and couldn't answer for a while.

She has always felt that Wang Minyi was seriously injured and she had an unshirkable responsibility.

If she didn't go hunting at that time, but stayed with Wang Minyi; If the first thing she did after going down the mountain at that time was to run to find Wang Minyi, maybe ......

Chen Ying shook his head suddenly.

In this world, there are no ifs.

It has already happened, and facing it squarely and solving it is the right way, and self-blame and guilt will not help.

"With penicillin, there is indeed a certain risk, and this risk is very fatal." Chen Yingqi said, a very soft voice, as if talking to herself: "It has a miraculous effect on wound infection, but not everyone can use it, if it is not used by people who are not suitable, it will have terrible consequences." ”

She looked up a little dazedly.

So, what to do?

How can this risk be minimized?

Chen Ying looked ahead, as if he wanted to look through this heavy curtain and look at the Cangyun Mountain.

Pei Shu came over with concern, the two looked at each other, and he smiled at her.

Chen Ying was stunned, and then smiled.

Somehow, such a look and smile made her feel at ease.

It is better to have someone to share the burden than to bear it alone, even if that person does not say or move, it is enough to stay with him not far away.

Pei Shu looked at Chen Ying carefully.

I haven't seen it for more than a month, she seems to have grown a little more, black eyebrows and beautiful eyes, clean and cold, on the green skirt corner of Xiangshui, is a crane with wings ready to fly, the crane beak next to a few poles to repair bamboo, leaves like splashing ink, the more she is clear.

The more Pei Shu looked at it, the more happy he became, and the corners of his mouth grinned to the sides.

He knew her very well, and knew that her face was calm at this time, but in fact, her mind was spinning, and maybe she had already come up with seventeen or eight clever plans, so he didn't bother her, but only looked at her from afar.

Just let her do what she's good at, and he'll just be by her side.

At this time, Chen Ying was indeed thinking desperately.

With the passage of time, many memories have been blurred, especially the memories of the first life, which are almost not left.

Suddenly, Chen Ying's eyes lit up.

By the way, how did she forget that important thing.

"Skin test!" She suddenly spoke, her eyes still looking up ahead, her eyes empty: "I remember, before using penicillin, you have to do a skin test." ”

She curled her lips and looked back at Zheng Ruhui: "As long as there is no allergic reaction during the skin test, the patient can use penicillin." ”

Penicillin skin test can distinguish between allergic and non-allergic people.

Chen Ying remembers that in modern times, once in a chemistry class, the chemistry teacher suddenly became interested and told them the history of penicillin development for a whole class, including skin tests and even the preparation of normal saline.

It's just that there aren't many things she can remember now.

But in any case, something is better than nothing, and if there is a way, you need to try it hard.

"The owner, but I don't know what the skin test is?" Zheng Ruhui stepped forward to ask, her eyes were blazing, and she subconsciously pinched her fingers in turn.

She is a medical idiot, and she will exhaust the answers to everything related to medical skills, otherwise she will not even be able to sleep.

Chen Ying didn't have time to answer her, but turned around to walk by the small bookcase, rolled up her sleeves, and wanted to take the inkstone, but a slender hand suddenly came out horizontally, and took off the inkstone first.

Chen Ying looked back, it turned out to be Pei Shu.

"Do you want pen and ink?" He asked.

The mellow voice carries a little cold, a little cold, and the old wine is also similar.

Chen Ying withdrew her hand and smiled at him: "There is a little marquis." ”

Pei Shu grinned, took the inkstone with his hand, picked up the ink strip next to him, and concentrated on studying the ink.

The servant of the Wang family happened to come from the inside, and when she saw this situation, her eyes opened wide in shock.

This is really rare, there has never been only red sleeves to add fragrance, and I have never seen a big black man add fragrance.

Pei Shu didn't care about others, he happily studied the ink, and his heart was so beautiful that he was bubbling.

It's rare to be able to help his daughter-in-law, he is happy, what do ordinary people know?

Chen Ying picked up a brush, put it in the pen wash and moistened it, and then turned to Zheng Ruhui: "The so-called skin test is to dilute penicillin in saline, reach a certain proportion, put this reagent into the syringe, and then inject it into the horizontal stripe below the person's wrist. This needle should not be pierced deeply, but only punctured through the skin. ”

She held the jade tube back, inspected the tip of the pen, and said in a casual voice: "Normally, after two moments, this skin test will work. If the patient is not allergic to penicillin, a white pinch the size of a mosquito bite will bulge on the surface of the skin; If the skin is red and itchy, it is penicillin allergy. ”

She suddenly remembered something, and turned her head to look at Zheng Ruhui: "How is Dr. Zheng's injection technique?" ”

"I'm a little more proficient than before." Zheng Ruhui whispered and looked at Wang You on the side.

Wang You still stood in place, looking worried, obviously not reacting.

The words of this big girl Chen are as straight as a book from heaven, Rao is a rich man, and he is also a little confused at this time.

Chen Ying also looked in Wang You's direction and said calmly: "Don't worry, I will think of a way not to make the third girl take risks, but this method will take some time to verify, please don't worry." ”

The voice is as clean as water, and it teaches people to be calm.

Wang You seemed to wake up, but his expression was still dazed.

Chen Ying raised his voice slightly: "Come here with the truth." ”

Zhishi has been helping in the inner room, and when she heard the sound, Chen Ying asked her: "Can the doctor give the third girl an arrow?" ”

Several imperial doctors have been discussing the method of diagnosis and treatment, and when Chen Ying left, the arrow on Wang Minyi's chest had not been removed.

Zhishi hurriedly replied: "If you go back to the girl, several adults are still discussing the medicine." The maid just went to take a look, and the three girls slept peacefully, but the arrow did not come out. ”

Chen Ying nodded, ordered her to guard again, and then turned to Wang You and said, "The imperial doctors are highly skilled, they should be able to come up with a safe way, and I will only make a backup here." ”

Penicillin is still too risky, and you can't use it.

Wang You nodded, walked to the side of the desk, and looked down at Chen Ying writing.

Chen Ying was trying to remember that chemistry lesson, and whenever she remembered it, she immediately wrote it down.

She still remembers the ratio of normal saline, 0.9 percent, but only distilled water can be used;

The ratio of penicillin to normal saline, Chen Ying also vaguely remembers, is about 1 to 10.

She writes while thinking, first put down the pen calmly, and after a while, she becomes thinking more and writing less, and sometimes she can only write a few words after a long time.

Everyone did not dare to speak out for fear of disturbing her thoughts.
