Medical Immortals come from the future

Chapter 111

"It's debridement!" Sima Qing corrected, "The current wound condition doesn't need debridement, just suture."

Open wounds are generally divided into three categories: clean, contaminated, and infected.

Strictly speaking, there are very few clean wounds, and accidental wounds inevitably have varying degrees of pollution.If the pollution is serious, the amount of bacteria is large and the toxicity is strong, it can become an infected wound after 8 hours.The local blood supply of head and face wounds is good, and debridement can still be performed on contaminated wounds 12 hours after injury. Debridement should be performed for open wounds within 8 hours, and debridement should be performed for wounds that are more than 8 hours without obvious infection, if the wounded is generally in good condition.If the wound has obvious infection, do not debride the wound, just wipe the skin around the wound, disinfect the surrounding skin, and open it for drainage.

And Zheng Shisan's wound is just the simplest clean wound, and the wound time is extremely short. From being scratched by a dagger to now, it has only been about 10 minutes. To be on the safe side, she also did simple cleaning and disinfection So debridement or something is unnecessary.

"Sewing? Are you going to use these needles and threads to sew up my wound?"

Seeing Sima Qing picking up the needle and thread on the table, Master Zheng Shisan asked in horror, for some reason, he felt that the whole person was not well.

"Yes, how will your wound be better if you don't sew it up?" Sima Qing seemed to be talking about a very ordinary thing.

"No, miss, it's not that you can mend clothes if they are torn. You are too scary, not to mention that your female celebrity has not been very good..." Chunxi also shook her head in fright.

Sima Qing ignored her last words and said, "Chunxi, you are right. Clothes can be mended if they are torn, and human skin and muscles can be mended if they are torn."

Chun Xi: "..."

Zheng Shisan: "..." Is it true that you still want to mend the master's arm as a torn clothes?
Seeing the expressions on the two of them, Sima Qing couldn't help but want to laugh: "Don't worry, okay? It's not what you imagined, the needle and thread used to suture wounds and the needle and thread used to mend clothes are naturally different! You must never use the thread mending clothes to suture the wound, it will not help at all, and it will cause further infection."

Seeing that the two of them still didn't understand, Sima Qing sighed, knowing that it would take time for them to accept these things, so she stopped talking, took out another small medicine bottle from the first aid kit, and poured out a few red pills. Xiaowanzi gave Zheng Shisan: "You put this medicine under your tongue, it can relieve pain."

This medicine is a traditional Chinese medicine analgesic pill that she has researched and refined in the past two years. It is made of pure Chinese medicine and refined from more than 40 Chinese medicinal materials in the space. The bottle is with me, and the rest is donated to other patients in the valley.This medicine has a relatively good analgesic effect on trauma and bone injuries, and it works quickly. Although it is not as good as those special painkillers in later generations, this medicine has no side effects, and it will not cause any dependence. Therefore, the two It was very popular in [-], and many patients in the valley have used it.

Of course, for suturing such a large wound, the potency of this drug is definitely weaker, at least a small local anesthesia is required, but she has no better way, because there is no anesthesia in the snow lotus space medicine!Sima Qing protested to the God of Space about this, but she was shamelessly dismissed. The God of Space only told her that anesthesia is a special reward, and that it will be rewarded to her only when a special conditional system is activated.

A certain host just thinks that this dead space is simply using life to die!

"Although this medicine is used, the suture process will still be a little painful later, can you hold it back?"

"Heh, just go ahead. Is your master really like that kind of person who can't help the pain? Second Master Guan doesn't even wrinkle when he scrapes the bone to heal the poison. It won't hurt like that, right?" Zheng Shisan smiled easily .Of course, he wouldn't say anything if he was so scared in his heart!

"It shouldn't be more painful than that." Sima Qing really compared it seriously. After all, she also took her exclusive secret painkiller, and it will still be effective!

"Miss, I really, really need to sew..." Chunxi still felt a little numb.

"Yes!" Sima Qing rolled her eyes at her. If she is so timid, how will she be an assistant in the future? "Look carefully at the side, be serious, don't blink."

Seeing that her young lady was serious, Chun Xi could only purse her lips and nod her head.

Sima Qing took the instruments and began to suture.

Tissues and organs in different parts need to be sutured in different ways.Suturing can be performed with needle-holding forceps, or directly with straight needles with bare hands. In addition, there are skin staplers, digestive tract staplers, and closers.

"When suturing the wound, there should be no dead space and the tension should not be too large. Important vascular injuries should be repaired or anastomosed; ruptured tendons and nerve trunks should be repaired and sutured, and exposed nerves and tendons should be covered with skin."

Sima Qing did not forget to popularize knowledge to Chunxi while doing her hands.

I saw her holding the tweezers in her left hand, lifting the skin edge of the wound, holding a needle forceps in her right hand, using her wrist and arm to rotate in from the outside, piercing the skin along the arc of the needle, and passing through the skin edge of the incision on the opposite side subcutaneously. The toothed tweezers are pulled out along the arc of the front end of the needle, and the needle holder is pushed forward from the back of the needle at the same time...

Just like that, she shuttled the needle and thread over his wound, her movements were extremely neat, but her needle and thread were not sewing clothes, but skin. This kind of visual impact, no matter for Chunxi or Zheng Shisan, was undoubtedly important. It is shocking.

"There are several methods of suturing, and this one is the simplest 'simple interrupted suture method', a type of suture method that directly joins the two sides of the incision margin. It is easy to operate and most widely used. Knotted separately, mostly used for suturing skin, subcutaneous tissue, muscle, aponeurosis..."

"It is necessary to ensure a good alignment of the sutured wound or wound. Suture should be carried out in layers, according to the anatomical layer of the tissue, so that the tissue layer is tight, do not get involved or sewed into other tissues, and do not leave a residual cavity to prevent fluid accumulation. Blood and infection. The margin distance and needle spacing of the suture must be uniform, so that it looks beautiful, and more importantly, the force and shared tension are consistent and the suture is tight so as not to leak. Pay attention to the tension of the suture. Ligature and suture The tightness of the thread should be based on the close connection of the edges of the incision, and it should not be too tight. In other words, the healing of the incision is not completely proportional to the degree of tightness. Too tight or too loose can lead to poor healing..."

Sima Qing didn't care about their expressions, and concentrated on sewing. As for the popularized knowledge, she didn't need to think about it at all. Those theories had already been memorized in her mind, and she just said it out of her mouth.

Chunxi felt that the kung fu of her young lady was much better than embroidering on clothes or being a female celebrity!
"Watch out Chunxi, this is called inserting a needle, this is pulling out a needle..." Sima Qing deliberately slowed down her movements so that Chunxi could see it more clearly.

This is a pain for Mr. Zheng Shisan, who is regarded as an "exhibit". Girl, you are stitching Lao Tzu's wound, not embroidering!
In fact, Sima Qing's stitching speed is already very fast. The wound about 8 cm long was basically stitched up in less than 15 minutes, including occasional stops to explain and demonstrate to Chunxi.

When the needle is about to be pulled out completely, the resistance is very small. Sima Qing releases the needle holder, and continues to pull out the needle with tweezers alone. The needle is fully withdrawn, then the knot is quickly tied and the thread is trimmed.

With a bang, the needle holder and needle thread were gently thrown into the iron plate on the table.

"It's done." Sima Qing smiled easily.

Zheng Shisan couldn't help but heaved a sigh of relief, stretched out his arm and looked, and saw that the long opening that had been cut just now had been completely closed now, but the black stitching on it was like a centipede. It looks really hideous and weird.

"It's... just like this?" He was still a little unbelievable.

"Yes, the stitching is done like this." Sima Qing replied, "But of course it's not to keep your wound like this. After about seven days, when your skin is fully healed, the stitches on it must be removed." , can't stay there."

"It still has to be removed? If it is removed, won't the wound open again?"

"Haha, of course not! Do you still think this suture is really the same as mending clothes?" Sima Qing took out a roll of bandages and said, "Clothes are dead, but the skin and tissues of our human body are alive." , has the function of automatic repair and recovery. Using this needle and thread to suture the wound is actually just to help the muscle and skin heal and regenerate better and faster. When the skin and muscle are reassembled, these threads are useless. Then It has to be dismantled, or it becomes an obstacle.”

This time, although the two of them still only half understood, they seemed to understand better than the previous few times.

Chunxi curiously stretched out her hand, poked the wound on Zheng Shisan's arm... next to it, and asked, "Does it really not hurt?"

Zheng Shisan thought for a while and said, "It still hurts, but that's all."

Sima Qing thought to herself, it's no wonder that it doesn't hurt. There is no high-efficiency anesthetic or special painkiller. After all, the needle passes through the skin. Even if she takes her traditional Chinese medicine for pain relief, it won't have a significant effect. If ordinary people would definitely be in pain, this man could not make a sound during the whole process, he is really a pure man.

Afterwards, Sima Qing wrapped his arm with a bandage a few times, bandaged it and fixed it, and said: "Don't touch this wound within seven days, don't get wet, don't eat spicy food... By the way, this bottle of medicine Here you go, the wound may still hurt these days, take this medicine three times, twice a day."

Zheng Shisan took the bottle of medicine, touched the bandaged wound, and said with some admiration: "Girl, you are really amazing."

Sima Qing chuckled: "I'm sorry, this is just a trick."

Sutures are really just the most basic means of surgery in Western medicine. For her, they are "small skills and small dishes".
