Xiao Yu walked outside the temporary operating room, Bai Ling stood in front of the door, and when he saw Xiao Yu coming, he hurriedly greeted him: "Auntie...... Childe, everything is ready as you say, and there is no dust at all! Bai Ling proudly raised his feather duster.

"Okay, Bailing is really powerful." Xiao Yu smiled and complimented, "Childe, I really can't live without Bailing." ”

Bai Ling listened and excitedly spun around in place twice.

Bai Ling pointed to a room next to him: "Wash your hands and change your clothes in this room, the water and spirits are ready, and the potion boiled by Doctor Qin's recipe." ”

Xiao Yu nodded and looked around. The guards of the Yuanwang Mansion stood in the courtyard, and the commander of the army who patrolled the city that night actually didn't leave, squatting in the corner with his hands in his sleeves, looking like a lively turtle.

Xiao Yudao: "I need two assistants, are there any volunteers?" ”

The guards of the Yuan Wang's Mansion glanced at each other: "We don't know medical skills, how can we help Doctor Feng?" ”

"You don't need to know medical skills, just listen to my command." Xiao Yu said as he walked into the wash-washing room, "If you want to come, come to this room, you must wash your hands thoroughly first, and change into clean clothes." ”

Erjiu looked at the slightly hesitant colleagues around him, and stood up first: "I'll count one, I've seen Dr. Feng practicing medicine in Huaiqian City, and I'm not too unfamiliar." ”

Feng Zhaoyu seems to know more than ordinary doctors, isn't he just dirty and tired, he is not afraid, this wounded person is alone, no matter how dirty and tired he is, he can deal with the excrement of dozens and hundreds of patients every day when Huaiqian is treating the epidemic.

Erjiu followed Xiao Yu into the house, and everyone in the courtyard fell silent again.

The second one to stand up was actually the Wu Commander, he got up from the corner and stretched his arm: "Then I will also recommend myself in the next place, I have also bandaged the wounds of my injured brothers in the army, this is also experience, right?" Although there are not many who survived. So saying, he walked to the house.

"Boss." The two soldiers hurriedly stopped him, "Didn't you say that you should be nosy so as not to get into trouble?" What are you doing with it? ”

"This is not the other. He can't make up the excitement, but he can make up the excitement. Captain Wu laughed as he entered the house, only to be so anxious that a few small soldiers jumped straight behind him.

Xiao Yu had already poured three basins of hot water, and Bai Ling picked up one of the basins and slowly poured it down with a large basin.

Xiao Yu washed his hands under the running water, and said to Erjiu and Nawu Chang: "Erjiu, and this—"

The Wu Chang smiled and said, "I've seen Doctor Feng below." Under his name is Ding Peng. ”

Xiao Yu said: "Erjiu, Ding Peng, you look at my handwashing steps, you must be meticulous and strictly enforced." "The wounded were injured in the heart, and most of them had to undergo thoracotomy surgery, and he had no antibiotics, so he could only be as rigorous as possible in terms of sterility.

When surgery first developed in Western medicine, the operating table was like a Roman gladiatorial arena, with the surgeon performing the operation and the patient in the center of the amphitheater, and the audience could sit in the circular staircase around it, watching the operation with an uncertain outcome as if it were a play.

Xiao Yu didn't know what the probability of success of the operation was at that time, but there were always people who survived the infection of the surgical hand, right? Not to mention that he is now so strict with his hands and sanitization.

Forget it, psychological comfort is better than nothing......

Erjiu and Ding Peng stood aside and watched Xiao Yu wash his hands all the way to his elbows, and finally washed them again with spirits.

"Come on, you two, take off your coat first." Xiao Yudao.

Ding Peng took off his robe three times and five by two, revealing his strong and dark chest, this person only wore a layer of clothes in winter. Put on the clean shoes that Bai Ling brought, and Bai Ling waited for him and began to wash his hands.

Erjiu turned around a little awkwardly, avoiding Xiao Yucai and starting to take off. Regardless of whether Dr. Feng is a man or a woman, he is always the sweetheart of his family. Doctor Feng doesn't pay attention to it, he has to pay attention to it......

The two quickly washed their hands, put on a cotton robe in the same way as Xiao Yu, and covered a smock that reached to the ankles outside, wrapped their hair, mouth and nose, and raised their hands to their chests.

Xiao Yu glanced at the two of them: "Come with me." ”

Ding Peng was looked at by those two calm eyes, and couldn't help but stand up straight, and put away all the habits of hanging Erlangdang.

I always feel like this kid is like a different person after changing his clothes? With such a pair of ancient eyes without waves, where is there still a trace of frivolous youthful atmosphere?

Xiao Yu was the first to step into the temporary operating room, and in the center of the operating room was a low couch moved from the window, on which the injured man was lying, and there was a wooden table beside him with a variety of surgical instruments and medicines.

Xiao Yu said to Erjiu: "Give him the anesthetic first." He gestured to the pot-bellied and slender spout kettle on the table, and Erjiu understood, picked up the kettle and put the spout against the throat of the injured man, and skillfully poured his stomach.

Xiao Yu picked up scissors and quickly cut the bloody clothes on the man's chest, spread a disinfectant towel, and only exposed the left chest that needed surgery.

Disinfecting the skin and rinsing the wound are all familiar things, and Xiao Yu took advantage of the time when the anesthesia was effective to carry out preoperative preparations neatly.

Ding Peng and Erjiu stood aside and watched, Ding Peng was still a little suspicious: "This person is obviously sad in his heart, and he has been lying outside for at least an hour, is he really not dead?" ”

"He's not dead." Xiao Yu said, "Although the breathing pulse is weak, it is quite regular, and this person is not as seriously injured as you think." ”

Although the heart in this chest is injured, it is still beating hard to maintain the supply of the main body, and the heart is not dead, and this person is far from death.

"It's not heavy to break your heart." Ding Peng sighed, "Little doctor, don't boast about Haikou." ”

Xiao Yu said while rinsing the wound with salt water: "It's not a boast of Haikou. If the wound on the heart is large, it will cause you to lose too much blood and die within a few quarters of an hour. However, if the wound is not large, it may be blocked by a large blood clot, or the oil in the body, or even the lungs, and the bleeding will be temporarily stopped, but it will not die so quickly. ”

Ding Peng and Erjiu couldn't help but feel a pain in their chests when they heard him say what his lungs were blocking the wound on his heart to stop bleeding.

Xiao Yu continued: "If he can survive until now, he should belong to the latter." As he spoke, he had already cleaned up the mess on the wounded's chest, clearly revealing a knife about three centimeters long, and the skin and flesh on the side of the wound had turned white and bloomed.

Xiao Yu put down the tools in his hand, looked at the body on the couch without blinking, frowning slightly and thoughtfully.

Erjiu waited for a moment, but didn't see him move, and couldn't help but call: "Doctor Feng? ”

Xiao Yu turned a deaf ear and was still thinking quietly.

There are no X-rays, no ultrasounds, and all the qi qi can only be judged by experience......

Xiao Yu flattened the man's wrist and touched his fingers to the pulse, carefully picking up the pulse.

Seeing his familiar action, Erjiu and Ding Peng breathed a sigh of relief. This is what a doctor should do.

After a small wound on the heart temporarily stops bleeding, blood flows into the pericardial cavity, which is prone to bloody pericardium or cardiac tamponade.

What are the symptoms if cardiac tamponade occurs?

Xiao Yu's eyes flashed the textbooks as thick as bricks, the pages turned rapidly, and the dense five-point font flashed in front of him......

Signs of cardiac tamponade, tachypnea, jugular venous distention, rapid and weak pulse, and distant, weak heart sounds. Pulses paradoxus may be present, with the pulse disappearing on inspiration and becoming stronger at the end of expiration, or the venous veins may be markedly distended during inspiration.

Xiao Yu took the pulse while observing the breathing of the injured person.

In the absence of these symptoms, cardiac tamponade can be ruled out.

"Open your chest right away and do a heart repair." Xiao Yu finally blinked, and the voice under the mask came out muffled.

Erjiu and Ding Peng looked at him in disbelief: "What do you do immediately?" ”

Xiao Yu glanced at them: "The injured person has a wound on his heart, and I'm afraid there is blood in his left chest." Although the bleeding of the wound has temporarily stopped, it has not healed and must be repaired manually and the blood in the chest cavity must be removed. ”

To have thoracotomy surgery, Xiao Yu was more worried about the hypovolemia caused by the large amount of blood loss of the injured person, and the blood volume must be replenished.

But at this time, where to give him a blood transfusion?!

Xiao Yu picked up the scalpel from the white cloth on the table and looked at the man again.

Do your best and listen to the destiny of heaven.

Before Erjiu and Ding Peng could react, they saw that the sharp blade had already cut neatly on the man's dark skin, which was incredibly sharp, and blood beads came out instantly.

"Ding Peng, use gauze to wipe the blood clean." Xiao Yu didn't raise his head and said, without waiting for Ding Peng to say anything, Xiao Yu said again: "I said it before I came in, listen to my command." ”

Ding Peng pursed his lips, picked up a large stack of gauze resting on the white cloth and stepped forward, wiping the blood beads that came out.

"I didn't say I wouldn't listen to you."

The left anterior external chest incision was made through the fourth intercostal space into the chest, and after the chest cavity was opened, the injured part was exposed to the field of vision, and a large amount of blood had accumulated in the chest cavity of the injured person.

Xiao Yu stopped.

Erjiu looked at his delicate movements, Rao is hands already had several lives on his hands, and he couldn't help but want to retch.

He was wrong, he thought that only one person to be treated, it would definitely be much easier than the dozens or hundreds of patients when Huaiqian was treating the epidemic. He couldn't have been more wrong.

It's not easy at all, it's clearly more ...... I'm crazy.

Who does the prince have a crush on?!

"Twenty-nine." Xiao Yu's voice suddenly rang in his ears.

Twenty-nine excited, reflexively stood up, no longer retching, and responded in a loud voice: "Yes." ”

"You go out and call Bai Ling, and ask her to find some blood-invigorating herbs, what blood vine, safflower, red peony, is the potion that keeps the blood from coagulation, the doctor outside must know. Let her get it quickly, immediately, immediately, as soon as possible! ”

"Yes!" Erjiu didn't dare to ask so many questions, so he responded neatly and rushed to the door to call Bailing.

Xiao Yu looked down at the blood in his chest again.

There are no conditions for blood transfusion, aren't these? This method of autologous blood transfusion can also be used in wartime or in the event of a shortage of blood.
