Drinking black tea calmly at Hogwarts

More than 20 minutes after Scarlett left, she returned to the ward with the Grangers carrying a first aid kit.

At this time, Zhang Xu was measuring Mr. Weasley's blood pressure.

Due to excessive blood loss, Mr. Weasley's blood pressure is now very low.

The Grangers who came to the ward did not exchange pleasantries. While checking Mr. Weasley's injury, they communicated with Zhang Xu and the therapists about Mr. Weasley's injury.

But it was all the therapists who were talking about something so magical that the Grangers couldn't understand, so Zhang Xu replaced it with words that they could understand.

On the contrary, some of the questions raised by the Grangers were also asked by Zhang Xu to translate them for the therapists to listen to.

After some communication, everyone began to formulate a treatment plan.

Zhang Xu only knew the other person's name when the blood type was tested just now. The chief therapist Heber Crates Mesik said: "We can easily solve the patient's rib fracture. The biggest problem we face is the patient's massive blood loss and exposure to toxins." The wound caused by the impact of the wound cannot stop bleeding and heal."

Hearing that the wound had stopped bleeding, Mr. Granger looked at the wound on Mr. Weasley's rib with a thin layer of ice, and his face twitched.

Then Zhang Xu pointed to the Pichu formed on Mr. Weasley's forearm due to the skin test and said: "Just now I gave Mr. Weasley an antivenom allergy test, and the result was negative."

"But my antivenom is a broad-spectrum antivenom, and the snake's venom contains a special compound toxin that has been modified by magic, so it can't completely neutralize the toxin, but it can solve the problem of wounds that cannot stop bleeding. The only problem is that the speed of wound healing will still be affected by some toxins."

Zhang Xu looked at the Grangers and said to them: "Just like broad-spectrum antibiotics, they are effective against most bacterial infections, but have limited effects on some special bacteria."

Just now Zhang Xu observed Pichu for a while in front of the antivenom manual, and found that there was still a trace of black line on Pichu.

After making a small cut with a scalpel next to Pichu, it was found that there was no problem in stopping the bleeding, but the healing of the wound was affected.

After all, it is an antivenom made from the venom of a young basilisk, and Voldemort's snake is probably upgraded, so it is not as effective as the venom of the thousand-year-old basilisk.

Zhang Xu then pointed to the blood type test strip on a small table next to him and said: "Mr. Weasley's blood type is O, and among our people, only this Mr. Augustus Pye has O blood type." type."

Augustus Pai was an intern therapist at St. Mungo's Hospital. When Zhang Xu first arrived at Hogwarts, he was in the seventh grade. Both of them were students of the Eagle Academy, and they also brushed the copy of Quirrell together.

Over the years, Augustus Pai, who aspired to become an excellent therapist since he was a child, has always wanted to try the treatment methods such as blood transfusion and stitches mentioned by Zhang Xu before, but he never had the opportunity.

"Can I transfuse a patient?" asked Augustus Pye.

Mrs. Granger looked at Augustus Pye and said, "Some diseases are transmitted through blood. Are you in good health?"

According to the standard procedures of modern hospitals, blood donated by blood donors must be tested before it can be used for transfusion.The direct blood transfusion method is only used as an emergency treatment method in places such as battlefields and disaster first aid.

But in Mrs. Granger's subconscious mind, in the magical world, it should be no problem to treat most blood-borne diseases.

After all, Hermione often told her parents that after the bones in her arms disappeared, they drank medicine and grew back.

Mr. Granger often thought when he was pulling out the kid's tooth, it would be great if his daughter could directly remove the cavities of the kid, so as not to hear the kid tearing it up.

Heartbreaking cries.

And Mrs. Granger's question is only out of professional habit.

"There's nothing wrong with my body, I don't have any disease," Augustus Pye said.

Augustus Pye was very excited to experience a blood transfusion for himself.

Mr. Granger said at this time: "I am also type O blood, and I can also give Mr. Weasley a blood transfusion."

"And one person should not donate too much blood at one time. I am physically stronger than you, and I donate more blood than you at one time, so let me transfuse Mr. Weasley."

"Since the wound is slow to heal, I can finally put stitches into the wound."

Augustus Pai looked at his small body, and had no choice but to give up the position of blood donor.

Later, when he heard of stitches, Augustus Pye's eyes almost lit up.

"Then let's give Mr. Weasley a blood transfusion and inject antivenom at the same time, and then treat the wound." Zhang Xu said after summarizing.

Although several people wrote a lot of words together, it only took a few minutes.

After the treatment began, Zhang Xu was glad that he had invited the Grangers. After all, it was best to leave professional matters to professionals. The half-bucket of water he had practiced on Wangcai could be done by tying a vein. Make a star in the sky to join the Big Dipper.

After more than 100 years of development, direct blood transfusion has also been regulated accordingly.

As an emergency blood transfusion method, the Grainger couple, who were trained in majors, were no strangers to the direct blood transfusion method, especially Mr. Granger, who had served in SAS, had received corresponding training back then.

The direct blood transfusion method is different from the two people in Zhang Xu's imagination lying separately and connected by a tube in the middle. This ancient method has been eliminated.

Mrs. Granger took out the largest intravenous syringe and two largest needles from the first-aid kit they brought, and Zhang Xu felt a little frightened.

After adding a small amount of anticoagulant into the syringe, Mrs. Granger drew a tube of blood from the hand of Mr. Granger who was lying on another hospital bed next to him, and then only pulled out the syringe but not the needle. Stupei can reduce the bleeding by applying pressure on the distal end of the vein with his fingers.

After a new needle was replaced, the blood was injected into the vein on Mr. Weasley's hand. Here, Zhang Xulai pressed the distal end of the vein with his fingers.

The three steps of blood drawing, transmission and blood transfusion that should have been completed by three people can only be completed by Mrs. Granger now.

Generally speaking, a person donates less than 40050 blood at a time, but this time Mr. Weasley lost too much blood, and he was worried that there would be accidents in the waiting treatment, so the Grangers decided to donate 80 blood at once after discussion. blood.

This is a very dangerous amount for an adult, but due to the existence of unscientific but magical blood tonic, Mr. Granger did not experience any side effects of excessive blood loss.

As the blood in Mr. Weasley's body was replenished, his body functions improved, which in turn promoted the absorption of the blood tonic that had been poured into his stomach earlier, and his face gradually became less pale.

After injecting Mr. Weasley with the antivenom prepared by Zhang Xu, Mrs. Granger went to rest aside. She was exhausted tonight.

With the antivenom still taking about an hour to take full effect, St. Mungo's healers began preparing for the final treatment.

Zhang Xu, on the other hand, took Mr. Weasley's blood pressure every once in a while and observed whether he had any adverse reactions.

Mr. Weasley's face began to flush as the antivenom took effect.
