More than twenty minutes after Scarlett left, she returned to the hospital room with the Grangers, who were carrying a first-aid kit.

At this time, Zhang Xu was taking 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 greet each other, and while examining Mr. Weasley's injuries, they exchanged information about Mr. Weasley's injuries with Zhang Xu and the therapists.

However, it was all the therapists who were saying that something that was too magical for the Granger couple to understand, Zhang Xu replaced it with words that they could understand.

On the contrary, some of the questions raised by the Granger couple were also translated by Zhang Xu to the therapist for them to hear.

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

Just now, when Zhang Xu was taking the blood type, the chief therapist of Hebkerate Smesuik, who only knew the other party's name, said: "The patient's rib fracture can be easily solved by us. The biggest problem we face is the massive blood loss of patients and the inability to stop bleeding and heal wounds due to toxins. ”

Hearing that the wound had stopped bleeding, Mr. Granger looked at Mr. Weasley's thin ice wound on his ribs, and his face twitched.

Then Zhang Xu pointed to the pichu on Mr. Weasley's forearm due to the skin test and said, "I did an allergy test for antivenom on Mr. Weasley just now, and the result was negative. ”

"But my antivenom is a broad-spectrum antivenom, and the venom of this snake 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 that the wound can't stop bleeding, but the speed of wound healing will still be affected by some toxins."

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

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

After making a small infusion with a scalpel blade next to Pichu, it was found that the hemostasis was fine, but the healing of the wound was affected.

After all, it is an anti-venom made from the venom of a young basilisk, and Voldemort's snake is estimated to have been upgraded, so it is not as easy to use 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 type O, and among the people here, only this Mr. Augustus Pai has a blood type O. ”

Augustus Pye was a trainee therapist at St. Mungo's Hospital, and when Zhang Xu first arrived at Hogwarts, he was in seventh form, and both were students at Eagle Academy, and they had also brushed Quirrell's copies together.

Over the years, Augustus Pay, who has aspired to be an excellent therapist since childhood, has always wanted to try the blood transfusions, stitches and other treatments mentioned by Zhang Xu before, but he has never had the opportunity.

"Can I give a blood transfusion to a patient?" Augustus Pye asked.

Madame Granger looked at Augustus Pay and said, "Some diseases are transmitted through blood, are you in good health?" ”

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

However, in Mrs. Granger's subconscious, in the magical wizarding world, the treatment of most blood infectious diseases should be fine.

After all, Hermione told her parents about things like the bones in her arms that grew back after drinking the medicine.

Mr. Granger often thinks about how good it would be if his daughter had just gone away with the bear's tooth decay and save him the heart-rending cry.

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

"I don't have any problems with my body, I don't have any diseases." Augustus Pye said.

Augustus Pay was thrilled to experience a blood transfusion firsthand.

Mr. Granger then said, "I also have blood type O, and I can give Mr. Weasley a blood transfusion as well." ”

"And the amount of blood donated by a person at one time should not be too much, my physique is stronger than yours, and I donate more blood than you at one time, so it is up to me to give Mr. Weasley a blood transfusion."

"Since the wound heals slowly, I can give the wound stitches at the end."

Augustus Pai looked at his small body and reluctantly gave up his place as a blood donor.

Later, as soon as he heard the stitches, Augustus Pay's eyes lit up.

"Then let's give Mr. Weasley a blood transfusion and antivenom injections before we treat the wound." Zhang Xu summed it up and said.

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

After the treatment began, Zhang Xu was glad that he invited the Grangers couple, after all, it is best to leave professional things to professionals.

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

As an emergency means of blood transfusion, the Grangers are no strangers to the direct blood transfusion method. Mr. Granger, who served in the service, had been trained accordingly that year.

The direct blood transfusion method is not the same as the two people lying down separately in Zhang Xu's imagination, and the middle is connected by a root tube, 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, which made Zhang Xu a little frightened.

After adding a small amount of anticoagulant to the syringe, Mrs. Granger drew a tube of blood from Mr. Granger's hand, who was lying in another hospital bed next to her, and then only pulled out the syringe without pulling the needle, but asked Augustus Pye to press his finger against the distal end of the vein to reduce bleeding.

After replacing the needle with a new one, the blood was injected into the vein in Mr. Weasley's hand, and Zhang Xulai was asked to press the distal end of the vein with his finger.

The three steps of blood drawing, delivery and blood transfusion, which were supposed to be done by three people, can now only be done by Mrs. Granger alone.

Generally speaking, a person can donate less than 400~500cc of blood at a time, but this time Mr. Weasley lost too much blood and was worried that the waiting treatment would cause an accident, so the Granger couple decided to donate 800cc of blood at a time after discussion.

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

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

Mrs. Granger had injected Mr. Weasley with the antivenom that Zhang Xu had prepared, and then went to rest, she was exhausted tonight.

It would take about an hour for the antivenom to fully work, and the therapists at St. Mungo's began to prepare for the final treatment.

Zhang Xu measured Mr. Weasley's blood pressure every once in a while and observed whether he had any adverse reactions.

As the antivenom took effect, Mr. Weasley's face began to turn rosy.
