[Infrastructure] Rose kissed Barcelona

"There are different types of human blood." Joy quickly explained, "There is no problem with blood transfusions of the same type, but transfusions of different types are very likely to cause transfusion reactions—that's why the mortality rate is so high."

"Ah..." The nurse looked at her in surprise, "Well, how do you know this?"

"I did an experiment." Joey didn't have time to explain too much.

When the two hurried to the vicinity of the operating preparation room, another nurse was checking the information of several blood transfusion recipients. "Mr. Muñoz? Okay, please follow this nurse to prepare for aseptic disinfection..."

"Wait a minute!" Joey stopped him, and gave a brief instruction: "First draw some blood from the patient, and bring it for examination."

"Uh, are you...?" The nurse receiving the blood transfusion turned her head suspiciously, "Ma'am, please do not enter the medical area for irrelevant personnel."

"She is Miss Gordy." The nurse who brought Joy quickly explained.He turned to Joey again: "However, Mr. Gordy has lost a lot of blood. Are you sure?"

Wouldn't that be more dangerous.

"I did the experiment." Joey repeated quickly, "Please believe me - I am his family. Please hurry up!"

"Ah," the nurse was stunned, "Okay, okay." He strode towards the preparation room.

"You are Miss Gordy?" The nurse who stayed behind stood up, he was a little excited, "I used the first aid technique you introduced to save people! It's amazing. What do you need me to do now?"

"Please trouble the gentlemen to take a little blood." Joey replied, "Ah, mine is fine too!"

Grasp the left hand with the right hand, stopping the slight trembling of the wrist and fingertips.She tried hard to control her brain not to think about the blood red she saw just now, and concentrated on searching every corner of her mind, recalling the mechanism of blood type.

It’s been too long since the college entrance examination, but most of her existing medical knowledge came from the biology class at that time—I don’t know whether it’s luck or misfortune, more than a century later, the medical knowledge of students who will only study hard is much better than it is now The most advanced doctors of this era must be clever.

But in this extremely tense situation, Joey couldn't think of the division method of several different blood types in the ABO blood type system for a while.And now that time is urgent, there is definitely no way to test the blood types one by one.

But fortunately, she still remembers that in blood of different blood types, there are antigens and antibodies that can cause blood coagulation reactions in red blood cells and serum respectively.

The corresponding relationship can’t be remembered for a while, but she knows that in her previous life, she had type O blood, also known as the “universal blood transfusion person”; and type AB blood is the “universal blood recipient”—of course, usually only in emergencies use.In the most ideal situation, blood transfusion of the same blood type is still required.

At this moment, she could only pray for God's blessing, that Antonio must not be of Rh-negative panda blood.Then she really has nothing to do.

Joey breathed steadily and tried to clear his mind: "Every piece of blood must be separated from red blood cells and serum."

"Ok."

Thank God.Because of the invention of the microscope, doctors today at least know the existence of red blood cells.

"When you get Antonio's blood sample, use the serum from other blood samples to mix with his red blood cells, and then use the serum to mix with the red blood cells from other people."

Joey thought nervously, wishing the reaction was visible.

When the scene was busy, a middle-aged man's voice suddenly came from behind: "Miss Gaudi, what do you want to do? The operation is in progress, and the patient's condition is not optimistic. Blood transfusion is needed immediately!"

Following the nurse was Leon, a highly respected surgeon at St. Paul's Hospital.

"Yes, I have heard of your name of saving lives, but do you know that we are already racing against death?" He stared at her angrily, with a cold gleam in his eyes: "I tell you, although you are the family member of the patient, But if malicious interference with medical treatment leads to serious consequences, we will not hesitate to prosecute you. You may face the charge of intentional homicide."

To be honest, working in the hospital for decades, he has seen the ugliest human nature.In the current situation, the injured only belonged to this family member... Usually it meant that when he died, the inheritance would go to her.

Is she really trying to save people?

I'm afraid only God knows.

Joey pressed the wound on his hand with a cotton ball, and replied calmly: "You have this right. But now, we need to do a cross-test immediately."

She raised her head coldly and glanced at the doctor: "I will not sign until the test is completed."

Although it is impolite, politeness is no longer the most important thing now.She doesn't care what they think of her, she just wants to save people.

Time is very urgent, if it is later, the blood will probably coagulate.

Antonio must be fine.What if... Joey suddenly felt dizzy, as if the symptoms of blood dizziness reappeared.

She pressed hard on the wound, and the pain from her hand made her tremble again.

No time to think, focus.

It was like the most important exam that year. During the countdown, I forced myself to calm down and write the most perfect answer I could.

Leon blushed with anger, gritted his teeth and replied: "...Okay, I'll just stay here and watch you!"

He turned his head and yelled at the nurse at the side: "What are you doing in a daze? Hurry up and do what she said!"

It's so unscientific.Leonyi was indignant in his heart.The law is always so rigid and impersonal—after so many years, doctors are still under the control of family members!

As he was thinking, he watched with a dark face as the nurse mixed the patient's serum and four parts of red blood cells in test tubes according to Miss Gordy's instructions, and quickly shook them well.

Another person did a similar operation, but mixed the patient's red blood cells with the four serums separately.

After shaking, the eight samples, numbered zero to eight, did not appear to make any difference.

Joey's heart sank gradually.Is her method wrong, or is it really such bad luck that none of the four people match in blood type?

Boundless cold and despair hit from all directions.

There was really nothing else she could do.

After wasting so much time, do we still have to resign ourselves to fate?

A bitter fire spread in the bottom of my heart, igniting the severe pain of tearing.

Leon couldn't stand it anymore.He took a step forward and glared at Joey viciously: "Miss Gordy, have you experimented enough? This is the medical area, I'm afraid I'm going to invite you out..."

"Doctor Leon!" A sudden exclamation came, "It has changed, it has changed!"

Another nurse's eyes widened in surprise: "There has really been a change!"

Leon turned around sharply.

Among the two neat rows of test tubes, one row of four showed no reaction, while in the other row, three of them all showed a small amount of floating agglomerates.

A row of unresponsive test tubes mixed with patient serum and donor red blood cells.

The row of three test tubes that showed a reaction was the patient's red blood cells and the blood donor's serum.

A light flashed in Joy's mind—she seemed to understand it all at once.

In the clinical medicine of the 21st century, whole blood is rarely transfused, and red blood cells are usually transfused.Therefore, if conditions permit, all four of them can give Antonio blood transfusions—he has a high probability of being a "universal blood recipient" with type AB blood.

And right now, no matter what, at least one person can give him a blood transfusion.

"Mr. Muñoz, your blood should be fine!" She excitedly shook the gentleman's hand, "Thank you very much!"

Leon was still staring at those test tubes in disbelief, and murmured, "This, is this true...Why didn't we think of it before?"

After a person who dies from a transfusion reaction undergoes medical autopsy, it is often found that the blood in the body has clotted.But doctors have never tried testing blood clotting before transfusions -- because blood clots after death, with or without a transfusion.

Although he didn't know what the reason was, it was obvious that if the other test tubes were coagulated and only this gentleman and the patient's blood did not coagulate, then their success rate of blood transfusion would be much higher than that of others.

"Doctor Leon!" Miss Gordy's trembling voice brought him back to reality: "It's ready now."

She looked at him earnestly: "I didn't have a good attitude just now—please forgive me. I believe in your skills, please save him."

Dr. Leon stared at her deeply, suppressing the countless questions in his mind. "Miss, please rest assured."

Watching the backs of them leaving, Joey suddenly felt a sense of loss of strength, so he had to sit down against the back of the chair.

She was still a little worried, "One person's blood transfusion may not be enough, can we find another person?"

The nurse was completely fascinated by the novel experiment just now, and said repeatedly: "Yes! As long as you give me a little more time, I can find many people."

"Hey, so we can't help?" The other two who participated in the cross blood test just now looked a little disappointed, "Our...then what, the red blood cells, didn't they clot too?"

The person who spoke glanced at the test tube, and his face was a little embarrassed: "Ah, but now it's condensed."

"Coagulation is normal now." Joey explained, "After all, no anticoagulant was added."

What was the anticoagulant in biology class at that time?

By the way, it should be sodium citrate.Seems like yet another thing that wasn't used in the 19th century.

She suddenly thought of a question: "Gentlemen, thank you very much for your enthusiasm... In times of need, you will save other people's lives."

Blood transfusion is a miracle of modern medicine, as if life is shared between organisms.

She hesitated again and again, but still couldn't help but asked in doubt: "However, I would like to ask, why are you so actively willing to donate blood?"

Even in the 21st century, when the management of blood banks is already very perfect, there will often be situations where blood banks are in a hurry.However, in the 19th century when there was no blood storage technology, blood transfusions could only be made from live people, so the possibility of finding a suitable blood source in time was greatly reduced.

But in fact, it seems that the difficulty is not so great, and three volunteers can be found in such a short period of time.

"Oh, bloodletting can not only save people, but also improve your health." One person replied, "Even if no one needs blood transfusion, I will come here regularly to do bloodletting."

"Yes. I live nearby, and it only takes a few minutes to come here." Another person nodded in agreement.

Joey froze.

……I see.

She suddenly remembered that when she read "Robinson Crusoe", it seemed that bloodletting therapy was also mentioned.

All right.She was in a complicated mood for a while, and didn't know what to say.

After thanking several volunteers again, she was guided by the nurse to the waiting room outside the operating room.

This is a hospital in the 19th century, and the doctors are all wearing gray and black robes.Accompanied by the pungent smell of disinfectant, the whole room looked dark and oppressive, as if sealed in a huge stone.

A sycamore tree leans in from the window, and the lush branches and leaves bring the only touch of greenery.

The waiting time was long and anxious.

The sky gradually darkened, and the hospital seemed to quiet down a little bit.

Joey seemed to be thinking about a lot of things, but he didn't seem to think about anything.The air froze into a thick jelly, and her vision flickered, and from time to time, a piece of red or green residual color flashed, like a spent old movie.

I do not know how long it has been.

"Miss Gordy."

A vague voice seemed to come from far, far away.

Joey raised his head in a daze, only seeing a oppressive black robe.She couldn't even see the face of the person who came, who was vaguely wearing a beak-shaped mask of terrifying shape.

"Miss Gordy...we are truly sorry."

The author has something to say: Thank you Rose for the cute mine!

Sorry for being a little late, the author of QAQ found that all the live broadcasts he watched won the championship! !So think hard and think I should make the most of it, watch the game instead of writing (bushi)
