Chapter 370: Difficult surgery

, , , , , , , , , ,
Before the operation, Yan Yan checked the large box that Liu Qingsong generally did not leave.
"冉颜, this is the gut, I made it." Liu Qingsong carefully took out a long strip of metal from a wooden ice bucket and took out a piece of stuff wrapped with a silk peg. There are only two guts in the gut. This thing is as thin as a hair, but it is very hard, like a dead branch, but Yan Yan knows that this is a good thing. This is a line that can be absorbed by the body. It is suitable for suturing blood vessels. The place where the wire is removed must be stored at a low temperature for a long time, otherwise it will easily deteriorate.
There are also a variety of Liu Qingsong's own wound medicine, disinfectant potion, and almost a full set of scalpels, and even a magnifying glass!
Yan Yanyan was slightly wet, and she felt that Liu Qingsong was very necessary at this moment. With Liu Qingsong, a boring person who made these "boring" things, Yan Yan had a little more confidence.
Even with these things, Liu Qingsong feels that the success rate of surgery is limited. Sang Chen’s injury, even in a well-equipped operating room, is not a simple operation. In this environment, for the surgeon, It is a unique challenge, with four points on strength and six points on luck.
Although I thought so, Liu Qingsong did not care about the cooperation. He put the gut in the salt water and softened it, then returned to Yan Yan as a deputy.
Because in the wilderness, the lighting conditions are very limited, only all the torches can be ignited, and the officers and men stand around the grass house.
The cleaned grass house was in the middle, and two officers and men supported Sang Chen. Yan Yan had cut off his robes and exposed the upper body of the , and was removing the arrow a little.
At the beginning of each move, Sang Chen was sorely snorted, but in a half, he could no longer hear his voice.
Yan Yan looked at a lot of bleeding, the sound was tight, "Liu Qingsong, can you test blood type?"
"Yes." Liu Qingsong immediately said that when he came to Datang for more than a decade, he did not do a big deal. Instead, he came up with a bunch of unreliable inventions, and extracting serum is a rare success. Because it is usually the case, serum can also be obtained by natural precipitation.
However, one of the most important functions of extracting serum is to identify the blood type. In the absence of Western medicine, people need to know what their blood type is. Therefore, this technology can only be used as a trick for Liu Qingsong to occasionally lie to Xiao Niang.

Is there serum?
Yan Yan has been focusing on the wound, but the voice of the inquiry has brought a little joy.
The serum is in good storage conditions, but it is only a week's time. Under normal circumstances, it will stink in five or six hours. If there is serum in the temporary, it is definitely God's will to let Sangchen live.
"No, but I used to read a report that I can quickly extract serum. I have done it many times before. The chances of success are quite high." Liu Qingsong said, he got up and took a bottle out of the box, hesitating. Only said: "I have cultivated some anti-venom serum myself, but I have never done experiments..."
One of the most important functions of anti-venom is to prevent and treat tetanus.
Liu Qingsong has a syringe and a needle scraped from Yan Yan, and Yan Yandun has not been authentic, saying: "Let the late green disinfect the syringe needle with boiling water."
Liu Qingsong did not have any confidence in the anti-venom serum he made, but he felt that the syringe was made by Sangchen himself. Maybe he would be destined to save his life today, so he would not say anything anymore. .
The atmosphere inside the house was dignified, and everyone was not consciously slowing down even breathing. More than ten pairs of eyes were not instantly staring at the movements of Yan Yan.
She wore a mask, and the sweat on her forehead gathered in a beating fire, and the blue was constantly helping her.
Yan Yan has not been doing live surgery for many years. She only had a physical internship in the hospital during the period of graduation. Even the surgeon had never done it. After the year, she did the main knife, but only for the body. But today, Sang Chen’s life is in front of her eyes, and there is room for recovery. Even if she only has a chance of one in 100,000, she will never give up.
Sang Chen, stick to it again... Yan Yan secretly.
No instruments are available, and Yan Yan can only rely on visual inspection to observe changes in the signs of life and sangchen.
The arrow was taken away, and Yan Yan turned to Sang Chen behind him, took a deep breath, held the feather arrow with both hands, and slammed it.
When the time was full of blood and splashes, the face was full of sputum, but her expression did not change at all, and the voice was flat. "Put him flat."
Yan Yan quickly changed a pair of clean gloves, "fourth knife."
Liu Qingsong has a relatively complete surgical knife in his box. Although he usually has no chance to use it, he disinfects it every day. The model number is marked on each tool holder and knife body, and the song blue is easy to find.
After removing the arrow, Yan Yan did not sew it immediately. Instead, he first cut the wound with a scalpel in a gripping manner, and cleaned it slightly with a cotton cloth dampened with disinfectant.
"No. 7." Yan Yan put down the scalpel in his hand and reached for the longer scalpel that Song Lan handed over.
The No. 7 scalpel is a scalpel for deep cutting. Yan Yan is more familiar with the human body than the general practitioner. Almost every part of the human body has been dissected. The chest and abdomen is the most frequently dissected place for forensic doctors. After many years of forensic experience, according to the location of the injury and the amount of bleeding, etc., the position of the injured artery of Sangchen was judged, and the skin and muscle tissue were slightly cut along the wound, and the artery was quickly found in a fleshy blood.
"Hey." She took the sputum, holding the knife in the right, holding the sputum on the left, quickly and accurately peeling off the blood vessels, and then temporarily tying the artery with silk to avoid shock and excessive shock.
During this time, she drew blood from a large amount of cotton cloth to allow the blood vessels to be exposed more clearly.
The artery was not completely broken, but it was a little bit open when the arrow passed. Fortunately, Yan Yan’s judgment is correct. First, the idea is to remove the arrow before pulling it out. Otherwise, if this hand is pulled, as long as the hand is slightly undetectable, it may cause the blood vessel to break.
He Temple is sitting still not far away, watching this scene, the sweat on his forehead is more than the face, his hands clenched fists on his legs, his heart is both nervous and surprised, but he dare not Close, because Yan Yan said before, everyone in the house is not allowed to move, because the change of light and shadow will affect her sight.
His position can only see a flesh and blood, and a calm look.
After doing all this, Yan Yan explored the pulse of Sang Chen, and his breathing was gradually declining. When Yan Yan was only holding the blood vessels, the pulsation and bleeding volume of the heart that was obviously felt was already very weak.
Yan Yan took a deep breath, took off his gloves, and replaced it with a pair of softly wrapped guts from the salt water, so that the song blue was separated by a magnifying glass, and it was easily worn.
It is best to suture the blood vessels under the microscope, but with limited conditions, only a magnifying glass can be used.
Yan Yan dissected the finishing work of the corpse, the general suture only needs to look neat, it does not need to consider the effect on the human body after suturing, at this point, she can not compare with the doctor who has many years of surgical experience, but Usually practicing embroidering has helped her a lot, and sewing the fine stitches of the blood vessels can be done relatively easily.
"Let the lanterns come close." Yan Yan's voice did not have the slightest emotion, which made the listener awe-inspiring. The soldiers who were carrying lanterns did not need to speak at all, and they immediately leaned over.
In addition to the torches, there are four lanterns, and the official business in the night, these two things are essential.
Adjusting the best lighting position, Yan Yan will let Song Blue put the magnifying glass on top of the wound. She fixed the blood vessel with her hand and started suturing with a needle.
He Temple is looking at Yan Yan in the corner. She describes her wolverine at this moment. She is covered in blood, kneeling on the ground, squatting, seemingly so awkward and sincere, a pair of exquisite eyebrows have been wrinkled and never let go for a moment, but black and heavy. Only calm and focused in the eyes.
Song Blue is also very hard. She can't shake her hand with a magnifying glass. The other hand has to constantly sweat the face, so that sweat can't affect her sight or drip onto the wound.
In the absence of equipment such as an oxygen mask, the face must be finished as soon as possible in such a harsh environment.
Fortunately, the mouth that was hurt was not big, and the whole stitching did not last for a long time. However, everyone felt that it had gone through decades and it was exhausted. The soldiers with the lanterns were stiff and stiff, and they kept their hands from shaking. At this moment, they looked at Yan Yan’s eyes with admiration, because from the beginning to the end, the movements on the ground did not move. .
After suturing the blood vessels, Yan Yan quickly cleaned the wounds, untied the vascularized silk, and then began suturing the external wound. This is relative to the sutured blood vessels, which is very familiar.
However, Sang Chen can't change like a corpse. As time goes by, his signs of life are gradually stagnation.
Yan Yan had to suture the wound more quickly and then cardiopulmonary resuscitation.
These tasks, if it is normal, should be an assistant, but Liu Qingsong must deal with the subsequent rescue preparations. He wants blood tests, blood tests, and catheters suitable for blood transfusion. No one can replace them. So now, Yan Yan can only come by himself.
The blood vessels near the heart of Sangchen have just been sutured, and Yan Yan does not dare to press hard, only in the form of massage.
There is also important artificial respiration. When Yan Yan puts the head of Sang Chen and hangs his mouth to the mouth, the people who are already surrounded by the stunned, do not know what to do, just grow up and stare at this scene.
But Yan Yan is not a kiss. In a few cases, everyone basically sees it. She in the air and then passes it to Sang Chen. Even though it is really shocking to do so, no one has ever done this before, but isn’t the anatomy of Yan Yan’s anatomy not the magical technique used by Hua Tuo in legend?
Yan Yan does not stop, reciprocatingly doing cardiopulmonary resuscitation massage, artificial respiration.
At this time, Liu Qingsong came in and saw this situation. She quickly went forward to cooperate with her. Liu Qingsong made artificial respiration and made a heart massage.
After about two moments, Yan Yan explored the pulse of Sang Chen’s breath and finally had a weak reaction.
The two continued to spend a cup of tea until Sang Chen was able to resume his own breathing, even though it was very weak, but it was hope for survival.

Is the syringe disinfected?
asked Yan Yan.
Liu Qingsong called the late green to send the syringe and needle.
Yan Yan took off her gloves, took the syringe, took a little from the anti-toxic serum made by Liu Qingsong, and rolled up her sleeve. Because of the continuous operation, her hand holding the syringe constantly trembled.
Liu Qingsong grabbed her hand. "Yu Yan, what are you doing, can this thing be tried casually?"
"What should I do? He is now showing signs of weakness and can't hold the test!" Yan Yan opened his hand and his voice was flat.
