Yang Zixi remembered a less commonly used surgical method: cryogenic surgery.

The full name of cryosurgery is actually called cryogenic arrest surgery. To put it simply, it is to take advantage of the opportunity of lower temperature, stagnation of the circulatory system in the body, and slowing down of blood flow, delaying the operation time, and reducing heavy bleeding.

The human body temperature is 38 degrees Celsius, and the higher the temperature, the faster the blood circulates. This is why it is easy to get a fever when you are infected, because the body's immune system automatically removes the virus from the body. It is precisely because of the increased blood circulation that the body temperature rises, leading to the appearance of fever.

In the same way, when the blood temperature decreases, the blood flow rate will also slow down accordingly, and cryosurgery uses this principle to reduce the blood temperature of the human body from 38 degrees Celsius to 20 degrees Celsius, so that the blood circulation in the patient's body will be stopped, thereby reducing the occurrence of heavy bleeding.

It is equivalent to 'flash freezing' the patient, and then 'freezing' after the surgery.

But cryosurgery also has its limitations, and that is time.

The patient's 'quick freezing' time should not exceed 40 minutes, otherwise the brain ischemia and hypoxia time will be too long, which may cause irreversible damage. At the same time, the temperature control must also be very accurate, otherwise once the patient enters cold shock, it will not be able to be saved at all. Therefore, although cryosurgery is very effective in the treatment of emergency trauma, it is rarely used.

At this moment, these two patients who have been 'skewered together' may be able to give it a try.

Yang Zixi didn't want to do the multiple-choice question, in her eyes, there was no difference between the value of life, let alone if she only saved one and let the other die. It's an insult to her medical skills!

If you want to save it, save both of them together!

"Han Ye, you go to the warehouse and bring the electric ice blanket!" She commanded.

Han Ye turned around without saying a word. Chen Yuqing's eyes rolled and became excited: "Little Master." Aren't ice blankets used by people with high fevers? Or are you going to have any particular surgery? ”

"Cryogenic arrest surgery, I will give you ten minutes to memorize the preoperative and intraoperative precautions in the book! I'll need you to monitor me the whole time. ”

"Order!" Chen Yuqing clenched her fists and shouted, and hurriedly rushed back to the house to get the book. She was faintly proud in her heart, Xiao Shi and Li Xiaofeng were busy taking care of the disemboweling guy, but they missed this feast! Such a rare operation, only she and the senior brother can observe it!

Soon the ice blanket was brought in, and it looked like a vacuum cleaner attached to a nylon blanket, with two long tubes filling the blanket with cold air from the instrument. It can introduce cold air and quickly cool down in more than ten seconds.

Chen Yuqing excitedly turned the book to the page of cryosurgery and handed it to Han Ye, and the two began to quickly recite the precautions.

Yang Zixi once again checked the condition of Commander Cao and the little soldier Wang Bao, fortunately, these two were men in the prime of life, and their hearts were relatively strong, and they could afford this adventure.

After the examination, Yang Zixi began to explain the operation process to the two patients: "Commander Cao, I will cool you down later." You may feel cold, but don't panic, it's something we have to go through and soon you won't be conscious. Then I will pan you off the spear. I'll do you a blood vessel suture ......"

Because Commander Cao injured his spine, he was chosen as the one who moved. The reason why Yang Zixi planned to operate on him first was because his survival rate was almost half that of Wang Bao.

But Wang Bao replied to the wrong meaning. Instantly excited.

Since he was sent to the hospital, Wang Bao began to think wildly. There is no doubt that he and Commander Cao are simply incomparable. Although the soldiers who sent them did not say it explicitly, he could feel that they were ignoring him.

If two can only live one, they will definitely not have the slightest chance.

At this moment, when he heard that Yang Zixi said that he would treat Commander Cao first, he collapsed instantly!

Before Yang Zixi's words were finished, the little soldier Wang Bao howled and cried, and choked up while crying: "I...... I knew it...... You don't care if I live or die! You guys...... You commanded the envoy to save Cao...... Must be ready to give up on me! ”

As he spoke, he tried to raise his hand, ready to grab the spear and make his own nonsense!

Yang Zixi was startled, and hurriedly shouted at the people around him: "Stop him!" Don't let him move! ”

The reason why the two of them were pierced and they were able to hold on until now was because the spear shaft happened to plug the wound and did not further expand the injury. But any movement can cause the wound to burst, accompanied by massive bleeding, which can be fatal in less than five minutes!

In an instant, the entire room was surrounded by people, and Han Ye grabbed the shaft of the spear and fixed it to prevent it from moving; Yang Yi and Yang San pressed Wang Bao's arm on the left and right; Yang Er, Yang Si, and Yang Wu helped hold the rest of his body.

Wang Bao was forced by five strong men to struggle, but Yang Zixi quickly grabbed an empty needle, plunged it into the anesthetic and began to draw fluid.

"Wang Bao! Don't get excited! The wound is dilated, the internal organs are displaced, and it is over! ”

"Don't try to lie to me! You guys...... You're just going to hold me ...... Good to save Commander Cao! Wang Bao shouted hysterically under the suppression of everyone.

"Bastard!" Suddenly, Commander Cao, who was opposite him, scolded, and spat Xingzi sprayed Wang Bao in the face, "Can you have some chance?!" The spear can't be pulled out, but if you want to pull me out first, which of the two of us do you say is more risky? Moreover, a good man will die when he dies, and he will be a good man again eighteen years later! What kind of thing is a crooked woman's flowing pee! ”

Wang Bao was stunned by his scolding, habitually shrunk his neck, drooped his head, and closed his mouth.

Yang Zixi breathed a sigh of relief and put down the anesthetic in his hand. Since the operation is ready immediately, it is better to do without anesthesia or not, so as not to repeat the agent during the operation, which is difficult to control.

"I didn't have time to make my words clear," she continued, "The reason why I operated on Commander Cao first was because when he moved down from the spear, the wound would rupture suddenly, and the risk factor was higher, and it was necessary to sew up the ruptured blood vessel as soon as possible." It's not because he's a commander, and you're just a creep. ”

These words made Wang Bao completely calm down, no matter whether Yang Zixi was lying to him or not, he had only one way to believe in her at present.

"I will finish Commander Cao's operation within thirty minutes, and then Han Ye will be responsible for warming him up." Yang Zixi instructed, "Then there is Wang Bao's operation, first to cool down, then to remove the spear shaft, and finally to operate." Wang Bao, I know you're scared, so when Commander Cao starts the operation, I'll give you anesthesia at the same time, and you'll find that when you wake up, everything will be solved. ”

"Really! Am I really alive? Wang Bao asked with tears in his eyes.

"I'll do my best." Yang Zixi said.

Everything was ready to stop, Han Ye took the anesthetic mask and gave it to the two of them, and in a few breaths, Commander Cao and the little soldier Wang Bao both fell asleep. Yang Yi and Yang Er supported Cao Commander, Yang San and Yang Si supported Wang Bao, and Han Ye was in the center and tightened his grip on the spear.

Then it began to cool down, and the ice blanket draped over Commander Cao's body was full of cold, and soon Commander Cao's hair and nose were covered with hoarfrost.

To quickly reduce the temperature of the blood, the temperature outside the body is at least minus ten or twenty degrees, everyone in the room felt the chill, and some even hugged their feet and began to shiver.

"Thirty-five, thirty-two, thirty" Chen Yuqing stared at the instrument to report the blood temperature, "Twenty-eight, twenty-four, twenty-one......"

"His heart stopped." Han Ye said.

"Let's go! Yang Yi Yang Er, you two have to push the roller bed flat! Linear motion! Be fast! Yang Zixi commanded everyone: "Han Ye, Yang San, you fix Wang Bao!" One! Two! Three! Push! ”

With the cooperation of several people, the roller bed moved in two different directions, and Commander Cao was instantly removed from the spear shaft!

Because the freeze had sealed the circulation, there was even a little blood left in the wound on his chest.

"Knife 10." Yang Zixi took the equipment handed by Yang Huan and quickly stepped forward to start the operation, she only had more than 30 minutes!

scalpels, tweezers, sutures...... Artificial blood vessel walls, aspirators, scissors...... Yang Huan couldn't even catch up with Yang Zixi's hand speed when he delivered the equipment alone, so Chen Yuqing hurriedly put on gloves and stepped forward to help.

Yang Zixi put down the knife quickly, and kept reporting the name of the equipment needed, Yang Huan and Chen Yuqing rushed to deliver it, and Yang Zixi took the tool from the person who delivered it first and continued...... The smooth operation didn't even have time to pause and breathe, Han Ye stared at the countdown instrument, reporting the time every five minutes.

Thirty minutes, this is the time limit given to himself by Yang Zixi!

"Twenty-eight minutes, twenty-eight minutes and thirty seconds, twenty-nine minutes, twenty-nine minutes and thirty seconds, it's time!"

With Han Ye's final time signal, Yang Zixi pulled out the last stitch with tweezers.

"The artery is stitched up, give him a temperature increase!" Yang Zixi commanded.

Everyone got busy again, the ice blanket was removed, Sister-in-law Huang and Sister-in-law Yu and others moved in a large bucket of hot water, Yang Zixi adjusted the temperature, and ordered someone to soak the back of Commander Cao's envoy in warm water.

"After the temperature rises, we will repair other organs, Yang Huan, Yuqing, we will start to save the second one!" Yang Zixi led people to Wang Bao's operating table again......

"It's like a race!" Afterwards, when Han Ye explained to Wang Xiaoshi and Li Xiaofeng, he said, "I have been pinching the time to report the number, but the little master can always finish the planned operation within the last time." ”

"The three girls and I handed the knife in pairs, and the little master was even faster than us!" That's what Yang Huan said.

"I'm out of breath," Yang Yi said, "I was dizzy when I looked at the movements of the little master, and then I deliberately staggered my eyes and didn't look at the operating table." ”

"We were able to complete two major chest and lung repair surgeries in half an hour!" Chen Yuqing said a little proudly, "It's a pity that you didn't see it!" (To be continued......)
