The surgery is not very difficult, and in fact, the surgery that is too difficult cannot be done now.

Although Peng Yue was the most experienced, he was only among the few people present, in fact, he could only be helpless about the current situation, and the only solution was to cut off the carrion.

The knives are made of steel, baked at high temperatures, soaked in alcohol, and everything that can be done is done.

The cotton cloth that is constantly rinsed with warm salt water and is steamed and torn hard will break off will constantly suck away the contaminated warm salt water.

The wounded man suffered two main injuries, one on his left arm and one on his right calf, both of which were ulcerated, compared to the slightly less severe wound on the right calf.

As for the left arm, it is said that the lower arm was cut off at first, and the lower arm was amputated, but then the wound became infected and more serious symptoms appeared, so the entire arm had to be amputated.

But now the same thing is happening, and the wounded are still having a constant fever, a low-grade fever.

This time, Peng Yue did not choose to continue to intercept, there was no way to intercept it, cut off the carrion little by little, and then handed it over to the assistant to stop bleeding and bandage, and Peng Yue went to deal with the injury on his leg.

Here was shot by an arrow, the wound was not large, and it was not difficult to treat, but due to the passage of time, the area of ulceration increased rapidly, and the rotting flesh did not stop until the bone was seen, and at this time, even the color of that part of the bone changed slightly.

But Peng Yue obviously couldn't cut off the bones, he still dug out all the carrion, continued to wash it with warm salt water, and then bandaged it, and when all the procedures were completed, penicillin was injected.

The syringe used to inject penicillin is also very primitive, and there is iron to make the needle, but Li Yuanjing does not dare to use it, once he is infected with tetanus, it is useless even if the gods come.

In the end, the syringe was made of bamboo, and the needle looked very rough, similar to that used by later veterinarians, but there was no way, and at most it could only do this step, even so, the loss rate of the needle was still high when it was made.

"Injection in box A!" Seeing that the person in charge of recording took one out of box C, Peng Yue immediately spoke.

There is no hard and fast rule on which box to use, these are all random, but each casualty needs to be recorded, and the box used at the beginning must also be used in which box must be used next.

Different boxes represent different processes, and now they have no way of knowing which process is the best, so they can only use this method to investigate and explore little by little.

But it's not without a difference, at least Peng Yue knows that the penicillin in box A has the strictest process, and it has been purified, but it's hard to say what the effect is, it should be better than others anyway.

The recording staff put the penicillin back in box C and took one out of box A instead.

Peng Yue silently observed the wounded, in fact, the penicillin in the box has successful cases, but it has been improved by different processes.

According to the results of previous experiments, one is far from enough, and the effect of playing one stick a day is obviously better than playing two sticks a day, and it is precisely because of this that they thought of finding a way to purify it.

Many methods have been used, such as high-temperature distillation like extracting alcohol, but the extracted penicillin does not have any reaction at all, and no reaction means that the extraction fails, so this road does not work.

At this time, someone thought of Li Yuanjing's method of extracting juice, so he decided to use this method to give it a try, and the final test proved to be feasible, and in box A, there was only a large bowl of penicillin left after extraction, and the purity should be ten to twenty times higher than before according to the volume capacity.

Just when Peng Yue was a little hesitant, he suddenly thought of a passage left by Wang Henian when he was teaching them a few months ago, serious diseases need to be taken drastically, people are almost gone, what do you care about those sequelae? It's better to do anything than to save people first, and only when people are alive can they have a chance to solve other problems.

"Two!"

"Are you sure?" The recorder was stunned, this is purified penicillin, the theoretical purity is far greater than that in other boxes, this is the first test to dare to use two?

"Sure!" Peng Yue nodded heavily.

The two penicillin were injected into the wounded soldier's body by a crude needle, because the needle was too thick, he did not dare to pull it out directly after the injection, he had to stay in it for a while, let the liquid go farther before daring to pull it out, and after pulling it out, he had to press it, otherwise it would bleed with the needle hole.

The progress of the first wounded soldier was a little slow, but fortunately everything went well, and everyone finally breathed a sigh of relief when they saw the wounded soldier being sent out.

It took a lot of effort to take out the things that had been used just now and disinfect them, throw them away, clean them up, and the second wounded person was sent in.

As the number of people treated increased, Peng Yue became more and more proficient, and the operation speed became faster and faster, but the whole person also felt more and more tired.

By the time of the sixth wounded, Peng Yue already felt as if his body was not his own, and he could persist if he persisted, but if something went wrong, it would be over.

Even if he was unwilling, Peng Yue still gave up his position, moved a stool to sit on the sidelines, and personally instructed others to start the operation.

Although the speed is a little slower, there must always be a process, and Peng Yue does not think that he can handle all the wounded alone.

Of course, the medical officers in the barracks can also be used, but this group of wounded people wants to do it themselves, and only in this way can the data they learn can really be known.

The operation was from dawn to dark, the speed was not fast, and a team had just completed eleven units, and there were still twenty units waiting for them here, but Peng Yue was always worried that someone would not survive that time.

Who comes first and who comes next now is completely up to fate, and none of the people here are too ill, almost all of them have one foot in the ghost gate.

Ma Zhou did not continue to sit in the tent and wait for news, but as soon as the operation began, he came to wait outside the surgical tent.

Regardless of the wind and snow, Ma Zhou never left, no, every wounded soldier he dealt with, he would follow back, and personally told him to take care of it.

Later, it was really cold and couldn't do it, so he just followed the nearby soldiers to warm up the fire, from sunrise to sunset, he was busy inside for a whole day without dripping water, and Ma Zhou also froze outside for a whole day, and he also did not get a drop of water.

Seeing Peng Yue coming out of it, Ma Zhou immediately greeted him and said: "The wounded soldiers who have been dealt with are in good condition, at least so far, no worse news has been received, the first wounded soldier to deal with does not go away except for the low-grade fever, the others seem to be gradually improving!" ”

"I'm afraid that other people won't be able to get through it, and we really don't have the strength to continue doing it now, and the light inside is not enough, and my eyes can't stand it! I'm going to give each of the others one first, to see if I can help them delay, and the first five that I will deal with today will also play one for each person later, and the remaining few will play in the middle of the night! ”

"It's up to you to call these things!" Ma Zhou nodded, without any opinion on this.
