It's not that hard to open a hospital in another world, right?

Chapter 13 Allergy skin test?Make your own medicine

Since it is to be handled by modern medicine, it is natural to follow the ideas of modern medicine.Gray settled down and looked at the child again: what he observed before was right, the child's face was swollen, and there were lumps of wind on his face and hands, mainly due to allergies.He turned to the peasant woman who came in with the child, and continued to ask:
"No strange fruit? No flowers? Where did the child go this afternoon?"

"How can you play! Little Remy is sensible. Two years ago, he would help the family work!"

Uh...disrespectful.Gretel wiped away the cold sweat.How Yuan Shi's childhood lived, the memory has not been connected yet, he can't remember for a while.But in the previous life, at the age of seven or eight, he was clearly still a primary school student!
Carrying a small schoolbag and going to school every day, I didn't even have time to start thinking about how to blow up the school!
However, Grete knew how naughty seven or eight-year-old children were.In the past, when I was in the emergency department, parents rushed in every day with their children in their arms, injured, sick, for various reasons, and they were simply challenging the limits of human imagination.Sometimes adults can't think of it, and children's companions may not know-

"Are there any children working with him? Can you call in and ask?"

Gretel asked patiently.The peasant woman has not answered yet, but the farmer, Uncle Edmund, who is holding the child by his side, has already answered:

"There are! There are two or three! - What are you still doing, hurry up and call!"

Immediately someone ran away.Gretel frowned and continued to think hard, figuring out what the cause might be.On the other hand, after reading the priest in the throat of the child, he came over bored:

"Why are you asking these?"

Gretel: "..."

Check for allergens!

Gretel bit his tongue and almost stopped his words.Allergies, this word was very common in the past life, even if it was not a doctor, he would know what was going on.But say it in this strange world...

Gretel is [-]% sure that this curious baby priest in front of him will definitely ask the truth.When asked, how to explain?

——Hypersensitivity reaction, also known as allergy, refers to abnormal adaptive immune response that occurs when the body is stimulated by certain antigens, resulting in physiological dysfunction or tissue cell damage?
Very simple, very clear, there is only one sentence in the textbook...

It would be deadly to explain!
Don't talk about otherworldly worlds, even if Gretel asked a non-medical professional to explain the word "allergy" in his previous life, if you put a full set of 53 medical textbooks in front of him, he could struggle to turn the book for half an hour, and then shouted :
"Which book do you read for allergies?"

That's right, for half an hour, I didn't even read the book about allergies...

Fortunately, Gretel was the deputy director of the emergency department in his previous life. He was also very experienced in communicating with patients and their families.He sorted out the wording and answered slowly:

"I ask these questions to see if the child has eaten, drank, or touched something he can't stand."

"Poisoned?"

"It's not poisoning..."

Brother, who put the detoxification technique just now?Isn't that you?

After spending a long time talking and sweating, it was easy to explain the appearance of "allergies".The children's companions who played during the day were also called, there were three in total, the oldest was less than ten years old, and the youngest looked only four or five years old.Gretel carefully asked the question just now, and sure enough, he asked something different:

"It's salted fish! I saw Remy broke a piece of the salted fish hanging on the beam!"

"You nonsense! We Remy are the best, never stealing food!"

The peasant woman jumped up like a mother beast protecting her cubs, with her teeth and claws clasped and her voice sharp.The mother screamed, the child ran, the man stopped drinking, the hall became a mess, and the sound volume reached 120 decibels again.

Great Khan.He shouted with all his might amidst the noise of the hall:
"Don't be arguing! - Who is going to get that salted fish!"

No matter how much you suspect that salted fish is to blame, in the field of modern medicine, no doctor dares to make a diagnosis without doing an experiment.Gretel has a salted fish in his left hand and a bowl of water in his right, look left, look right—

"what fish is this?"

Forgive him in his previous life who only knew how to eat, never buy or burn.The cooked dishes are placed in front of you, and you can recognize what kind of fish it is. A raw fish is placed in front of you, this...

Can't do it, can't recognize it, say goodbye.

Fortunately, he didn't recognize it, someone else recognized it.The priest of the Spring Goddess stuck his head out, studied it for a while with great interest, and definitely came to the conclusion:
"It's the cod.—Is that what you eat?"

Cod is just right.Grete nodded secretly: People in this inland area usually can't eat sea fish, and it is normal to eat them once in a while to cause allergies.He smiled and nodded to the priest:
"I guess the possibility is not small. However, it still has to be verified."

"How to verify? - Let the child eat it again?"

"..."

Great Khan:
"The throat is so swollen, if you let him eat it, he will be able to swallow it!"

"What should I do?"

How to test, the doctors of the previous generations have paved the way for the latecomers.The doctor doesn't have to worry at all, suspecting an allergy, just send it for a skin test.

Do a few dozen yuan, poke two needles on the arm and drop a drop of antigen, and the result will be released within half an hour.But now, now...

To do a skin test, you must first have an antigen!
Antigens that are sterile, have no obvious toxic and side effects, and whose protein content has been measured, are placed in a large box in the laboratory, which seems to be readily available; but if there is no ready-made antigen product, it must be extracted from the raw materials...

Great's past life was a clinical major, not a pharmacy major.But he also heard the cry of his classmates in pharmacy. When he was doing the project, he extracted it himself. He had to cut the fish into pieces, grind it with liquid nitrogen, add acetone to remove the fat, stir, let it stand, and put it in a centrifuge...

It takes days and nights to walk down a set of procedures, so busy with unkempt facial features.As for how many medicines and instruments are needed in this process, it goes without saying.

In the previous life, various seemingly ordinary conditions were supported by the country's strong industrial strength.And in this other world, the only thing Gretel can be sure of is:

What he can currently do is the first step in the first step of preparing the antigen.

-Cut the fish into pieces and soak in water...

Gone.

Then, jump directly to the last step of the skin test.

"Bring two needles here! Another bowl of water!"

On the child's left forearm and right forearm, drop a drop of water and water mixed with fish meat, and then use two needles to penetrate the droplet and gently stab the skin, puncturing the skin, but not bleeding.Grete pinched his wrist, silently counted 60, wiped the droplets off the child's arms, and then—

"What are you doing now?"

"Wait."

Prick test in skin test, type I allergies—that is, seafood allergies, nut allergies, paint allergies, etc.—observe the results 20 to 30 minutes after antigenic stimulation.The child is temporarily out of danger, and the next treatment has to wait for the test results. What can be done now...

Just wait.

Look left, look right, sit where you are, doing nothing.

Gretel: "..."

No, it will take half an hour, no one will send me to eat? !
