Dark-Haired British Doctor Chapter 224

Episode 224 Blood transfusion [2]

Several needles had been made in advance.

Actually, aren't we in a time where disinfection isn't possible?

No, even in the days of good sterilization, needles were usually disposable.

If we are not careful, it could easily become a hotbed of infectious diseases.

Moreover, it is now the 19th century.

Even a person who looks healthy will probably be crawling with bacteria and viruses if you examine them.

I don't know, but… … .

“I wonder if our Lord Jamie here is carrying one or two of those age-old s*xually transmitted diseases, like syphilis or hepatitis C?”

“Why? Why not me? No way!”

Oh, and we didn't drain any blood from our Lord Jamie either.

It wasn't particularly out of respect for the elderly.

It was just medically dangerous.

Do you know why old people are old?

To put it simply, it's because I'm old.

Not only the outside but also the inside has aged.

If blood suddenly leaks out, the heart has to beat harder and faster to replenish it, while at the same time the blood vessels in the peripheral area have to constrict. Can our old Sir Jamie's body handle that?

“No, that’s not the reason.”

“Then why are you stopping me, a proud nobleman of the British Empire, from making the sacrifice?”

Can you say something like that?

The situation is already suspicious.

You have to give the right blood… … .

Haha.

Didn't you just blurt that out?

But you want me to talk about hemodynamics again?

That couldn't be possible.

“I think it would be bad if the age gap was too big!”

“Oh, I see. Aha.”

So I ended up saying something strange.

Something… … .

It's like the story of the witch who bathed in the blood of young men in the Middle Ages…

Well, it actually turned out to be a good thing.

Since there were already numerous stories with similar nuances, our Jamie Sir also understood it and moved on.

In fact, since Jamie wasn't even a direct descendant, it didn't really mean anything to me.

"ego……."

Meanwhile, I injected a needle into the patient's vein and drew some blood.

He put it in four iron containers and mixed it with the blood of the guardians.

Come to think of it, coincidentally there are four blood types.

Well… … it would be better if you take Rh- into account.

Let's just skip over it.

If you do something like that, I won't be able to have surgery!

“Hmm.”

“Is this true?”

“There is a matching blood… … This is too radical an idea.”

Anyway, we started looking at those four iron bars.

It didn't take that long.

Because if you mix with blood that doesn't match, it will mix right away.

Fortunately, there was one thing that held on without hardening.

“Huh? Is this really so?”

In less than a minute, we could all tell the difference between the hard and the soft ones.

The students were truly amazed.

So did Liston.

But it wasn't Blundell.

“No, actually, I’ve seen this a lot. When you mix blood, it just clumps together, right? I thought that the blood of sick people had that tendency… … .”

Would I have said something so radical without thinking, thinking I was crazy?

all…….

uh?

There are records from this era, that is to say.

Even experiments conducted over a century ago showed this.

Some blood clots, and some blood doesn't.

If you think about it, it's only natural.

This is a time when the spirit of experimentation has truly gone mad.

We just haven't been able to connect it clinically.

“If it weren’t for a country that fought so much like Joseon, well… … I could understand.”

Even so, since connecting itself is difficult, excuses had to be made.

“Huh… Is Joseon good at war?”

"hmm."

They say a lie begets a lie.

Was our country good at… …war?

At least they never invaded anywhere.

There is also a saying that we are a peace-loving people.

It's not a word I particularly like.

I said I didn't have the strength, and it sounded like the same thing over and over again.

'Ugh. Is this… the patriotism inside me?'

For a moment something stirred.

“A general named Eulji Mundeok even brought down the previous Qing dynasty.”

“Huh. Didn’t you say the country was much smaller?”

“The saying that a fight is 1 vs. 18 is a common saying in our Joseon.”

“18 people by yourself? Does that make sense?”

Blundell tilted his head.

Then I thought maybe I was being a bit harsh.

1 vs 18… … .

This is actually quite ridiculous.

“Why doesn’t that make sense?”

There was a salvation army.

Liston.

Haha.

18 people?

It would be difficult for 180 people to deal with one Liston with a knife.

In fact, momentum is much more important in a fight than you might think.

“There may be many people like me.”

“Oh, yes, yes. It’s not much, but it’s not that there aren’t any. People like Admiral Yi Sun-sin are part of the navy… … so, they’re like the Royal Navy.”

“Well, tell me. I like war stories.”

Now that we have confirmed that the blood is not clotting, the patient's older brother, who is the owner of the blood, is now in the blood bag row.

'Is up to 400mL safe?'

Will it be 400?

At best, it's one pack.

I don't know.

First of all, there is no suitable tool or method to measure it to that extent.

Actually, you shouldn't take it out like our Blundell did.

“He was a famous general who destroyed the Japanese army. He fought against 133 ships with only 12 ships.”

“Huh… … A great general like Nelson… … .”

“That’s what I mean.”

I made my brother lie down next to the patient, inserted a needle into the blood vessel, connected a metal tube to the back of the needle, and then inserted the needle into the patient's blood vessel again.

In fact, if my brother's position was higher, the blood would flow in faster.

Because it will create more pressure difference.

But if we do it artificially like that, our brother might die.

Above all, because it is an iron wall, if the direction is too wrong, blood may not flow well or the blood vessels on either side may be damaged.

“That’s amazing. I really need to go to Joseon sometime.”

Anyway, I finished this complicated task by talking about war.

Blundell started asking questions late, but that was okay.

I already connected it.

Besides, it's not without logic.

I also studied blood transfusions while preparing for a cesarean section.

It was no surprise, as one of the bloodiest surgeries I know of is gynecological surgeries, including cesarean sections.

“No, how can you do this? How can you bleed when you’re lying down the same way?”

“Haha. You know Robert Boyle?”

“I know. You’re a chemist.”

“That guy has already experimented with blood transfusions between dogs.”

“Experiment… …?”

“Okay. Okay, let’s think about it.”

Thank you, Boyle.

Boyle's Law was a headache to study and memorize, but it paid off in return.

Didn't the geniuses of the past delve into multiple fields rather than just one?

Boyle was the same way? He even gave her a blood transfusion.

They're not people, but dogs.

Anyway, it was quite an advanced… … better method than Blundell.

I don't think there was any particular medical consideration, but it does prove that the dog, if not the person, survived.

'It's a big deal if my brother dies, whether it's proof or not.'

Originally, when giving and receiving something, whether it was blood or organs, the giver was more important.

If a person who was not sick dies after receiving medical treatment, that would be a real disaster.

So I continued talking while observing the patient's facial expression.

“Now, if you dissect it, you’ll see that the blood vessels are all connected, right?”

“Yes. Well… … I haven’t found any tubes connecting the arteries and veins… … but I personally think there might be small blood vessels.”

“Haha, dude. There’s no rule that says it has to be like that, right? There’s even a theory that blood is made in the heart and then in the periphery.”

under.

What the fu*k.

I want to kill Liston.

But we can't kill it, so let's just move on.

We all know now that in the 19th century you shouldn't try to tell too much at once, right?

“Well… … Anyway, do you agree that there is blood in a confined space?”

“Of course, I said it would be connected by something small?”

“Well… … It’s the same space whether it’s being created or not.”

So I moved on.

Then I continued the story, which would have been difficult if I had thought about it alone.

Boyle.

He seems like a true genius.

“Well, then, that space is fixed and what fills it is blood. On one side, like this patient, a lot of blood has been lost. If it were solid, there would be empty space, but blood is liquid and when you dissect it, the blood vessels are soft, so what happens?”

“It’s going to shrink.”

“Yes. It becomes more certain when you feel the pulse, but it puts pressure on it.”

“Yes, blood pressure goes down. So the higher the blood pressure, the better.”

This time I wanted to kill Blundell.

How can you go around saying things so wrong so brazenly?

but…….

Well, it's not like I don't understand.

If your blood pressure drops, you die.

So, it's natural to think that high blood pressure is good.

This… …continued until the mid-20th century, which is a bit much.

This is something that you can find in the great classic <The Black-Haired US Army General>, so if you don't know, go and look it up.

Anyway, I passed this time too.

“Right. Okay, so this guy’s blood pressure is normal and this guy’s is low? Then what happens?”

“Ah… … Ah! So it’s going to push from a place of high pressure to a place of low pressure?”

“Yes. Boyle had already experimented with blood transfusions between dogs in the 17th century. He cut the blood vessels of one dog and let the blood flow out to lower its blood pressure, and then he sent blood from a healthy dog.”

“Oh, so if the pressure is equal, the blood won’t flow?”

“Yes, if that’s the case, then both of us will survive.”

“Aha, I see. This is… this is truly the perfect method!”

no.

If it were perfect, we would keep doing it this way, right?

Blood donation did not arise solely because of the ease of blood storage.

You said it would stop when the blood pressure equalized?

Is there any guarantee that blood pressure like that is normal?

It's nowhere.

What I'm saying is that there are bound to be cases where both of them end up dying.

Especially if you removed an area that is bleeding like now, it might not be so bad, but if there is a hole, blood will pour out like pouring water into a bottomless pit.

If you give them a blood pack, you can buy some time by giving them that and stop the bleeding.

So I gave you 10 and stuff.

If there are ten, then that person already has no blood left.

But do you do that while connected to a bio-pouch like this?

'Don't die… …don't die at all costs.'

It moves because of the pressure, right?

Is there a hole?

Then there is nothing to be gained other than making the blood flow faster.

Well, if that could buy some time and stop the bleeding in the meantime, then that would be another matter… … .

The problem is that it is an adventure that puts human lives at stake, not a waste of blood packs.

'Let's talk about it later.'

Yeah, it's alive now, right?

Okay.

I decided to laugh for now.

Even in the short conversation we had earlier, I realized that there were still a lot of remaining problems, such as blood pressure and such… … .

The more this happens, the more you have to laugh.

Otherwise you become the Joker.

This is a big problem.
