Chapter 363

Before the operation, ran Yan checked Liu Qingsong's large box.

"Ran Yan, this is catgut. I made it myself." Liu Qingsong carefully took out a long metal box from a wooden ice bucket, and took out a piece wrapped with silk handkerchief. There are only two catgut sutures. They are as thin as hair, but they are very dry and hard, like dead branches. But ran Yan knows that this is an excellent thing. It is a kind of thread that can be absorbed by the human body. It is suitable for suturing blood vessels and other places where it is difficult to remove stitches. It must be preserved in low temperature for a long time, otherwise it will deteriorate easily.

There are also various kinds of self-made wound medicine, disinfectant, and almost a complete set of scalpels in the box. There's even a magnifying glass!

Ran Yan eyes slightly wet, she felt at this moment that Liu Qingsong's existence is very necessary. With Liu Qingsong, a boring man, making these "boring" things, ran Yan has more confidence.

Even with these things, Liu Qingsong thinks that the success rate of the operation is limited. Even in the well-equipped operating room, sang Chen's injury is not a simple operation. In such an environment, it is an unique challenge for the chief surgeon. Four points depend on strength, and six points depend on luck.

In spite of this, Liu Qingsong's active cooperation was not careless. He put the catgut in salt water to soften, and then returned to ran Yan as an assistant.

Because of the Limited lighting conditions in the wilderness, all the torches can only be lit and held by officers and soldiers standing around the cottage.

In the middle of the clean thatched cottage, two officers and soldiers hold sang Chen. Ran Yan has cut off his clothes and robes, revealing his naked upper body. He is taking down the arrow little by little.

At the beginning of each move, sang Chen will be painful stuffy hum, but half a moment, then no longer hear his voice.

Ran Yan looked at a large number of bleeding, voice tight, "Liu Qingsong, can you test blood type?"

"Yes." Liu Qingsong immediately said that in the past ten years since he came to the Tang Dynasty, he did not succeed in any major event. Instead, he made a lot of unreliable inventions, and extracting serum is a rare and successful thing. Because usually, the serum can also be obtained by natural precipitation.

However, one of the most important functions of serum extraction is to identify blood type. In the absence of Western medicine, people should know what their blood type is for? Therefore, this technology can only be used as Liu Qingsong's occasional trick to cheat the little lady.

"Serum?" Ran Yan has been focused on the wound, but the voice of inquiry brings a little joy.

Under good preservation conditions, the serum only lasts for a week. Under normal circumstances, it stinks in five or six hours. If there is serum temporarily, it must be God's will to let sang Chen live.

"No, but I read an academic report before, and I can quickly extract serum. I have done it many times before, and the probability of success is very high." Liu Qingsong said, then got up and took out a bottle from the box. After hesitation, he said, "I have developed some anti-virus serum myself, but I have never done any experiments..."

One of the most important functions of antiviral serum is that it can prevent and cure tetanus, which is very necessary for sangchen.

Liu Qingsong here has a syringe and a needle from ran Yan's search. Ran Yandun's way says, "let the evening green sterilize the needles with boiling water."

Liu Qingsong didn't have any confidence in his anti-virus serum, but he felt that the syringe was made by sang Chen himself. Maybe he was destined to save his life today. So he stopped talking about it and went out to prepare.

The atmosphere in the room is dignified, and all the people even breathe unconsciously. More than ten pairs of eyes stare at ran Yan's movement.

She was wearing a mask, the sweat on her forehead converged into drops under the beating fire light, and Ge Lan constantly helped her wipe it.

Ran Yan has not had a live operation for many years. She only practiced in the brain Department of the hospital during the period of graduation. Even the chief surgeon had never done it. Three years later, she did the main operation, but only aimed at the corpse. But today, sang Chen's life is in front of her, and there is still room for recovery. Even if there is only one chance in 100000, she will never give up.

Sangchen, hold on Ran Yan secretly said.

Without any instruments, ran Yan could only observe the changes of the wound and sang Chen's life signs by visual inspection.

The arrow is taken off, ran Yan turns to Sang Chen, takes a deep breath, holds the feather arrow in both hands, and draws fiercely.

All of a sudden, blood splashed all over ran Yan's face. However, her expression did not change at all, and her voice was flat, "put him flat."

Ran Yan quickly changed a pair of clean gloves, "four knife."

Liu Qingsong has a complete set of surgical knives in his box. Although he has no chance to use it at ordinary times, he has serious disinfection every day. Each handle and body are marked with the model, which can be easily found by gellan.

After pulling out the arrow, ran Yan did not immediately sew it up. Instead, he cut the wound with a scalpel and cleaned it slightly with a cotton cloth stained with disinfectant.

"Number seven." Ran Yan puts down the scalpel in his hand and reaches for the longer scalpel handed over by Gelan.

No.7 scalpel is a kind of scalpel for deep cutting. Ran Yan knows the human body better than ordinary doctors. She has dissected almost every part of the human body, and the chest and abdomen are the most frequently dissected place for forensic medicine. Based on years of forensic experience, ran Yan can determine the location of the injured artery of Sang Chen according to the location of the injury and the amount of blood loss and other factors, and cut it slightly along the wound Skin and muscle tissue, and soon found that artery in the blood."Tweezers." She took the forceps, held the knife in her right hand and tweezers in the left hand, quickly and accurately stripped the blood vessels, and then temporarily tied up the arteries with silk to avoid shock caused by excessive blood.

During this period, she uses a cotton cloth to draw blood, so that the blood vessels can be more clearly exposed.

The artery was not completely ruptured, it was just a slight opening as the arrow passed by. Fortunately, ran Yan's judgment was correct. He first tried to remove the arrow and then pull it out. Otherwise, as long as the hand shook slightly, it might cause blood vessel rupture.

He temple is also kneeling not far away, watching this scene, the sweat on his forehead is more than ran Yan, his hands tightly clasped in his legs into fists, his heart is nervous and surprised, but he dare not close, because ran Yan said before that all people in the room are not allowed to move around, because the change of light and shadow will affect her sight.

His position can only see a piece of flesh and blood, as well as ran Yan calm expression.

After all this, ran Yan probes into sangchen's pulse, and his breath is also gradually declining. When ran Yan just clamped the blood vessel, he felt that the heart pulse and blood loss were very weak.

Ran Yan took a deep breath, took off his gloves and put on a pair of them again. He took out the soft catgut from the salt water and made Ge Lan wear it easily with a magnifying glass.

It is better to suture the blood vessels under a microscope. However, due to the limited conditions, we can only use a magnifying glass.

Ran Yan's final work of dissecting the corpse requires that the appearance of the suture be neat and tidy, and there is no need to consider the impact on the human body after suturing. In this regard, she is not as good as a doctor with many years of experience in surgery. However, her practice of embroidery helps her a lot in this matter. She can sew the blood vessels with fine stitches easily.

"Let the lantern come near." Ran Yan's voice did not have the slightest emotion, which made the hearers in awe. The soldiers with lanterns didn't need any more words from he temple, so they immediately leaned over.

In addition to torches, there are also four lanterns, which are essential for official business at night.

After adjusting the best lighting position, ran Yan asked Ge Lan to put the magnifying glass above the wound. She fixed the blood vessel with forceps in one hand and hung her head with a needle in the other hand to start suturing.

He temple is looking at ran Yan in the corner. At the moment, she describes herself as embarrassed, covered with blood. She kneels on the ground and lies on her back. She looks so solemn and devout. Her eyebrows have been tightly wrinkled and never let go for a moment. However, the only thing in her dark eyes is calmness and concentration.

Ge Lan is also very hard. Her hand holding a magnifying glass can't shake, but her other hand has to constantly wipe sweat for ran Yan, so that the sweat can't affect her vision or drip onto the wound.

Without oxygen mask and other equipment, ran Yan had to finish sewing as soon as possible in such a bad environment.

Fortunately, the wound was not big, and the whole sewing process did not last for a long time. However, everyone felt that it had been several decades, and everyone felt that they had lost their strength. Those soldiers with lanterns were stiff in their legs and held their hands tightly. At this moment, they looked at ran Yan with admiration, because she had never moved her kneeling on the ground from the beginning to the end.

After suturing the blood vessels, ran Yan quickly cleans up the wound, unties the silk that binds the blood vessels, and then begins to suture the external wound. Compared with the suture of blood vessels, ran Yan is really proficient.

However, sang Chen can not be like a corpse that does not have the slightest change, with the passage of time, his life signs are also gradually becoming stagnant.

Ran Yan had to suture the wound more quickly, and then CPR was performed on him.

Under normal circumstances, this work should be done by an assistant, but Liu Qingsong has to deal with the follow-up rescue preparations. He needs to have blood tests, draw blood, and find a suitable catheter for blood transfusion. No one can replace these. So now, ran Yan can only come by himself.

Sangchen blood vessels near the heart have just been sutured, ran Yan dare not press hard, can only use the form of massage.

There is also very important artificial respiration. When ran Yan straightens sang Chen's head and drops his head to his mouth, people around him are shocked and don't know how to react. They just grow up and stare at the scene.

But ran Yan is not a kiss. After a few times, everyone can see that she is breathing in the air and then crossing to Sang Chen. Even though this is really shocking, and no one has ever done this, isn't ran Yan's anatomy the divine skill that Hua Tuo used in legend!

Ran Yan does not stop, doing CPR massage, artificial respiration.

At this time, Liu Qingsong came in and saw this situation. He went to cooperate with her. Liu Qingsong did artificial respiration and ran Yan did heart massage.

About two minutes later, ran Yan explores the pulse of sangchen's nose, and finally has a weak response.

The two continued for another cup of tea, until sang Chen could regain her spontaneous breathing. Even though it was very weak, it was the hope of survival.

"Has the syringe been disinfected?" Ran Yan asked.

Liu Qingsong calls for night green to send in the syringe and needle.

Ran Yan took off her gloves, took over the syringe, drew a little from the anti-virus serum made by Liu Qingsong and rolled up her sleeve. Because of the continuous operation just now, her hand holding the syringe kept shaking.Liu Qingsong grabbed her hand and said, "ran Yan, what are you going to do! Can I try this thing at random? "

"What about that? His life is so weak now that he can't stand the test! " Ran Yan shook off his hand, and his voice was flat. (to be continued. If you like this work, you are welcome to start（ qidian.com ）Your support is my biggest motivation to vote for recommendation and monthly tickets. )
