Chapter 1617 Blood Donation

Hearing Zhang Zian's words, Megan and the elves were all stunned.

"Blood transfusion? You mean to transfuse the cat?" Megan subconsciously confirmed.

Zhang Zian nodded, "That's right."

Fina's eyes lit up. It was never willing to owe favors, but this time it owed a huge favor because of its own carelessness. Although the blood transfusion could not be fully repaid, it could at least make it feel better.

So, it was the first to jump out and said, "Blood transfusion? Use my blood!"

"Scared? Transfusion... blood transfusion?" Snow Lion shrank back in fright, as if he was afraid of grabbing it to draw blood, "Blood transfusion, doesn't it hurt?"

Megan asked further: "You mean...the blood of the other three cats is going to be transfused to this injured blue cat?"

The other three cats, of course, refer to Fina, Snow Lion and Xinghai.

Zhang Zian shook his head, denying both Fina's request and Megan's inquiry, "No, not with their blood."

Snow Lion heaved a sigh of relief, "I'm scared to death..."

Megan and the other elves were stunned, because there were only four cats in total, and without the blood of the other three cats, where could they find blood for the blue cat?

Zhang Zian's eyes fell on Feimasi at the door, walked over and squatted down, and patted its body, "Femaus, can I lend some of your blood to Vladimir?"

"what?"

"Gah?"

"Squeak?"

"Meow meow meow?"

As soon as these words came out, Megan's eyes almost popped out, and the jaws of the elves almost fell to the ground, and they couldn't believe their ears.

"Quack! You idiot, I can understand your mood, but are you confused?" Richard poked his head out of the hood and shouted.

Snow Lion: "It's over, it's over, the stinky man's head is flooded!"

Fimacs was also in a daze. It always thought that it couldn't help, "Uh... I don't care, but can I lose my blood to Vladimir?"

Megan rushed over and grabbed Zhang Zian's arm,

"Hey! Are you crazy? Although I don't know much about pets, no matter how you think about it, you can't lose blood from a dog to a cat, right? It will definitely cause serious rejection, not only can't save its life, but it will even..."

This is a cross-species blood transfusion. In her view, even if humans and monkeys can transfuse blood, cats and dogs cannot. After all, they are not even distant relatives.

"can!"

Zhang Zian solemnly gave an affirmative answer.

"Cats also have blood types. Most of them are type A, a few are type B, and very few are type AB. Just like humans, different blood types cannot be mixed." He looked at Vladimir, and then glanced at other cats, "but I I don't know what blood type it is, and I don't know what blood type they are, and it's a gamble to draw blood from any of them and transfuse it to Vladimir."

In addition to this worry, he was also not sure whether the blood types of ancient cats like Fina and Snow Lion were different from modern cats.

"However, even if it's gambling, it has at least half the winning rate. Didn't you say that most of them are Type A?" Megan still didn't understand, and neither did the elves, "But if you use dog's blood, isn't it Don’t you even have a 1% chance of winning?”

Zhang Zian took out the syringe from the first aid kit, which was found in the bathroom cabinet of this house.

"You don't understand, a dog's blood can be transfused to a cat, and you don't have to worry about the blood type." He explained while preparing for the blood transfusion, otherwise Megan might refuse to help.

"Since 1962, more than 60 cats have survived through transfusion of dog blood, and 4 related papers have been published. The general principle is that the cat's immune system will not immediately reject the dog blood cells transfused into the body for the first time. , It will take about a week or so to produce a rejection reaction." He said.

"Huh?" Megan was dumbfounded.

"The point is, the half-life of dog blood cells in cats is only 4 days! Do you understand? Before the cat reacts, all dog blood cells have died naturally, and 4 days is enough to survive the dangerous period of urgent need for blood transfusion!"

As a good student with both good character and academics, Megan finally understood that this was due to a time difference. The cat’s immune system reacted slowly to the dog’s blood cells. Therefore, there will be no severe rejection reaction, which is far better than randomly transfusing cat blood to try luck when the blood type is unknown.

"It's amazing...there is such a relationship between cats and dogs..." she murmured, "There must be a reason why God arranged cats and dogs to be the closest animal friends of human beings..."

"Is it the other way around? Transfuse the cat's blood to the dog..." she asked curiously.

"No." Zhang Zian said: "The reverse is not possible, and this is only an emergency plan after all, because a cat can only receive dog blood once in a lifetime, if it is the second time, even if the blood still comes from the same dog, Transfused to the same cat, the transfused cat also experienced severe rejection."

The cat's immune system may respond slowly the first time, but it is not stupid. It will firmly remember the characteristics of dog blood cells and mark them as invading foreign bodies. If dog blood enters the body again, it will immediately show no mercy If the dog's blood is treated as a foreign body to expel the immune offensive, it will not save lives, but will lead to the death of cats.

He is not very clear about the situation in North America and Europe, but basically all pet hospitals in China do not have cat blood banks, not to mention China, even Fusang, a neighboring country that is much richer than China and treats pets better, also has no cats In the blood bank, when blood is needed, it can only temporarily draw blood from healthy cats in the hospital.

What if there were no healthy cats in the hospital at the time, or if the cat was too old, too young, too weak for a blood draw? That can only be widely advertised, and enthusiastic people are invited to voluntarily bring cats to donate blood for free.

What should I do if the location is remote and no one nearby voluntarily brings cats to donate blood, or the situation is extremely urgent and there are no cats who voluntarily donate blood?

If there is a dog nearby, as long as it is a healthy adult dog, it can be used as a temporary emergency blood donor, and dogs are usually larger than cats, and the impact of blood donation is also small.

However, there are very few people who know this, very few, maybe occasionally someone has heard it as an anecdote, but they don't understand the principle, even most of the veterinarians in China don't know it, but fortunately he knows a professional who is a master veterinary.

Zhang Zian handed a syringe to Megan, "If you understand, get ready to start and follow my instructions."

"it is good!"

Megan took the syringe excitedly, with a sense of sacred mission in her heart.

Femus squatted by the coffee table, put one of his front paws on the table, "Come on!"
