Chapter 556

Human bones, very hard.

The bones of the limbs, long bones, are among the best in hardness.

Ordinary people need to use a high-powered bone saw for amputation, but Cao Yicong's right hand needs to be amputated is still such a different limb, which is likely to be more rigid.

In this case, even the bone saw will be blocked.

And worst of all, there's no bone saw, no other electric saw, no hand saw.

So when Gu Jun said that he wanted to amputate his limb, except for Cao Yicong, who was more and more confused, Li Liangbin and Wang Yong were in a daze. Although they were not the ones to perform the operation and they were not medical students, some common sense still existed, such as the environment and conditions

"Dr. Gu, what are you going to do?" Li Liangbin couldn't help asking.

Wang Yong looked around anxiously, also looking for where there was any sharp weapon that could serve as a bone saw.

In fact, it's better to have a kitchen knife now. After all, the most primitive amputation is basically to cut it off directly and then wrap the cut-off surface with cloth.

But they didn't bring any cold weapons. The pistol couldn't cut the limbs. The small scalpel on Gu Jun's hand couldn't cut the limbs either

"I'm going to do it with this scalpel, including the sawing process." Gu Jun said seriously, this is the only opportunity at present.

Li Liangbin and they were stunned, but Gu Jun knew that he was neither joking nor trying blindly. It was also the bone penetration of the leg of a black goat cub that could not even be sawed by the electric saw. It's not the bone saw in karop's instrument, but he has room to operate.

"This scalpel is extremely sharp." "Anything harder than iron and stone can be broken," he explained

"Dr. Gu If you think so, you can try... " Cao Yicong bit his teeth, and his mind wandered. He was able to endure the great pain until now. He is worthy of the investigation department of Dongzhou, "if not Just give me a Happy Don't hesitate, don't blame yourself... "

"Deputy!" Li Liangbin can't help but rush, Wang Yong also rose red face.

They know, they understand, they all have written a suicide note, changed their own position will also say so.

Not only do not want to be trapped in pain, but also because of the harsh swamp environment, materials are extremely limited, but we do not know where the end is and when we can get recuperation and supplies. The team will not allow such a situation, which can only drag down the wounded of the whole team.

But, how can you.

"I won't promise you." Gu Jun interrupted them and put the portable medical box on the ground. He took out a morphine from the box and put it on the intravenous injection needle. "Deputy Cao, I'll give you pain relief first. You just hold on. It's just an amputation. Don't think it's too difficult."

There was no time left. Every move he made was as fast as possible, and he had already arranged it in his mind before he made the action.

After grabbing Cao Yicong's left hand, he rolled up his sleeve to expose the thick blood vessels on the inner side of his left elbow. He pulled out the cannula of the needle, pinched the elbow of the injured person with one hand, and pricked the blood vessel with a suitable angle with the other hand. The blood return was very good. It was no problem to inject and return blood again.

Gu Jun has not done intravenous injection operation for a long time, but the skill that he has practiced from a small white mouse has not been lost. He has hit the nail on the head and completed it in one shot.

The heart just slightly relaxed this breath.

He knew that the more confident and quick he was, the higher the patient's confidence in disease resistance and the stronger his will.

If a needle was not punctured just now, I'm afraid Cao Yicong's chances of survival will be greatly reduced.

But now, just as he expected, Li Liangbin and Wang Yong had a big confidence, and their eyes were different. Cao Yicong bit his teeth harder because morphine was taking effect quickly and his mind became clearer. He was willing to try to support him with all his strength: "I try to hold on to it."

These investigators were most proficient in emotional manipulation, but they lost their balance in the face of illness and pain.

Gu Jun looked around and decided to carry out the operation in situ. There was no good position in the marsh around. The light was good, and there was also a small piece of hard mud for shelter. As for shadowless lamp, operating table, sterile cloth and so on, of course, none of them.

If it is in the surgical building of the medical department, CT and MRI examination will be done before the operation. Even if it is difficult to do an X-ray film to see the bone condition, it is not available now.

Looking at something in the small medical box, Gu Jun quietly took a deep breath. Ordinary tourniquet, several rolls of sterile gauze, two bottles of normal saline, stitching needle and thread

Karop's scissors, forceps, hammers, needles, and several common instruments.

There are procaine for local anesthesia and hemagglutinin for hemostasis

There are not many things, but there are opportunities. They must be done at one time. There can be no waste at all.

While thinking about the operation plan, Gu Jun has already taken up the tourniquet and tied it to the abnormal end of Cao Yicong's right upper limb. The position of the osteotomy plane will be about 5cm below the upper end of the humerus, almost to the scapula. From the appearance, the whole hand will be cut off.

Gu Jun's confidence comes from the right upper arm amputation that he just participated in. He still remembers the operation steps, intraoperative precautions, postoperative treatment and complications. He can do what he should now."Hemagglutinin, used to prevent bleeding." He added medicine and gave Cao Yicong intravenous injection, while deliberately explaining to continue to enhance their confidence: "the operation will definitely meet blood, don't worry, it is normal, I will ligate all the large blood vessels and other blood vessels, there will be no big problem without massive bleeding."

Wang Yong and Li Liangbin nodded when they heard the speech. Even though they knew that this was the words to comfort them, they still felt comfortable.

Gu Jun's skillful hand is well-known in the Tianji Bureau. It is not the first time that Gu Jun has completed the operation in the field. It is hopeful.

"Deputy, you can hold on." Li Liangbin is responsible for pressing Cao Yicong's right hand with both hands. Gu Jun asked Wang Yongxian to go up and press Cao Yicong's right hand before he started to make the skin flap. Once the blade moves the skin of the other limb, the force of movement will increase several times or even ten times.

One of the biggest difficulties of this operation is that the affected limb can't be easily manipulated, and there is a lack of fixed tools.

You can't give up those delicate operations just because it's urgent.

Even if he had a kitchen knife nearby, Gu Jun would not choose to cut off the affected limb directly. If the blood vessels were not handled step by step, the injured person would not be able to survive in this alien wilderness if he had too much blood during the operation, could not stop blood after the operation, and could not get blood transfusion.

Therefore, incision and flap must be done well, the higher the quality, the higher the survival rate.

Gu Jun made local anesthesia for Cao Yicong's right shoulder. He took up the kalop scalpel again and began the operation in this harsh environment.
