The humerus of the cavity, Gu Jun didn't care about it for the time being, and he couldn't take care of it, and now if he wants to take care of it, he can only amputate it up and do scapular girdle dissection.

Normally, the bone can also have cavity-like lesions, fracture reduction is also easy to have cavities due to the compression of cancellous bone caused by impact, which is not fatal, the most important thing in the current situation is to save the life of the injured, the key is to prevent bleeding and infection.

Originally, in order to prevent blood and fluid accumulation in the incision, and to reduce the chance of tissue reaction and infection, drainage must be placed before the incision is closed, and it is generally necessary to keep it for three to five days. But now that there is no drainage device around him, Gu Jun can only choose to have an open amputation.

After trimming the bone end, he rinsed the wound with normal saline, removed the bone chips, blood clots and fragmented tissue, and completely stopped the bleeding, covered the stump wound with a sterile gauze pad, and then sutured the flap intermittently for a few stitches to prevent the skin from retracting.

Finally, it was bandaged with an elastic bandage, and the amputation was completed.

Gu Jun didn't let go of his mind, and then used a stethoscope and a blood pressure monitor to measure Cao Yicong's vital signs, his heart rate, blood pressure, etc. were fine, his face was a little pale, but there was no heavy bleeding, such a tall and strong person would not lose too much blood so quickly, and he could still hold on.

"Vice Captain Cao, how many fingers are here?" He asked, raising the three fingers of his right hand.

"Three ......"

Cao Yicong's mental state is fine, and he can answer a series of questions he asked, but there is some numbness in the stump of his right arm, and it is accompanied by phantom limb pain, so that he can feel his lost right hand, "Doctor Gu, I feel that my right hand is still ...... But there was a burst of pain, like a pinprick prick. ”

Li Liangbin and Wang Yong didn't quite understand what this meant, but Gu Jun's heart sank, and he only felt that his surroundings were even colder and darker.

Phantom limb pain is one of the common complications of amputation, and the pathogenesis is not well understood, and there is no effective treatment.

However, the symptoms of patients with heterodysesis before amputation are similar to those of patients with BIID. Patients with BIID crave the amputation of their limbs, and after the amputation is completed, there will be no phantom limb pain, only pleasure and satisfaction. But now patients with anodysalia once they get rid of the heterogeneity, it seems that it will be an amputation reaction of ordinary people.

"Vice Captain Cao, it's normal, it's usually fine after a while." Gu Jun said.

Phantom limb pain generally goes away gradually, and only a few people have severe and long-term pain, which he hopes is not the case with heterodysesis.

Now Cao Yicong can only endure it first, and Gu Jun's other worry is that when the local anesthesia in the operation area has passed, the injured person will have severe physical pain and more serious phantom limb pain. There is not much morphine and procaine left in the carry-on medical kit, so you have to save it.

Then, he cleaned, disinfected and stitched up the facial and hand injuries of the three people, and completed the field first aid.

At this time, Gu Jun breathed a sigh of relief, cleaned those dissecting instruments briefly, and took off the gloves that had been heavily contaminated.

Now the remaining supplies are extremely insufficient, and the water is not enough for the four of them to drink for a day.

There was no sign of clear water in the surrounding swamps, only stinking rotten water, and thousands of dirt were buried in it. The severed limb before could still beat on the muddy ground, Li Liangbin and Wang Yong were exhausted, Gu Jun was busy with the operation, and in an instant, it jumped into the mire and sank.

Maybe at this moment, the strange hand was at their feet, but it was hidden deeply, deeply.

This environment is full of dangers.

"Guys, let's go, and see if we can get out of this swamp."

Gu Jun's gaze was fixed in a direction, it was difficult to judge the southeast, northwest, and northwest here, but if the basketball hoop was the base point, Lin Jing's house was over there, and that was also the direction of the entrance to the alley.

The legs and feet of the three were not injured, but Cao Yicong was a little weak, and Li Liangbin and Wang Yong supported him.

Gu Jun returned the pistols of Li Liangbin and the others to them, took Cao Yicong's one himself, and walked in front carefully. There were places in the mire where the mud would sink if he stepped on it, and he had to walk very carefully, and before each step fell, he had to test it gently.

The gray sky seemed to be the same color forever, and the occasional crow crow could come from the branch of a dead tree.

They walked for a while, about two hundred meters, which was long enough to get out of the alley.

There was still a lot of saprolite around now, but they still found that there were patches of hard concrete on top of the mire, the roofs of the villagers' houses, which should have been ten or ten meters above the ground, but now they were all sunk in the mire.

"Doctor Gu, it seems to be Lin Jing's house."

At this time, Li Liangbin pointed to a roof.

Lin Jing's house is a two-story old house, built in the 80s of the last century, and has never been renovated, so the roof is still the old-style design with a half-tiled roof, and the TV antenna stand that was once used has not been removed, and has become the logo of the house.

On the roof sunk in the mire, there was a TV antenna stand crumbling.

Gu Jun looked at it and nodded silently, that's right, there it is.

The houses in the alley had sunk into the swamp, making it impossible for them to find anything. And...... I don't know what happened to the villagers and celestial personnel inside and outside the house, whether they escaped and survived, or sank with the house.

They didn't find any trace that could indicate the answer to this question, Wang Ke and others, Lin Jing's parents, all disappeared.

The Lin family's house was located in the middle of the alley, and the four of them continued to walk cautiously in the direction of the entrance of the alley, and the depth of the surrounding houses gradually deepened, and even the roofs could not be seen, and the dead trees in the distance became more and more sparse and withered.

If this is an abnormal area like the last Mobei, there will be a dividing line, and they can pass through the dividing line and return to their own earth world.

But this hope was soon extinguished by the vision in front of him.

Gu Jun and the three investigators had never seen anything like this, and at the entrance of the corresponding alley after the distance was widened, from the mud swamp to the high clouds, a wall-like membrane-like thing enveloped the whole world, and the membrane was between transparent and turbid, making it impossible to see the other side clearly.

With such a high membrane wall, they should have been able to see it from a distance, but in fact they could only see it when they got closer.

As soon as Cao Yicong saw the heavy membrane wall, the phantom limb pain suddenly became more intense, and his left hand pressed against his right arm, which did not exist.

"What's that......" Wang Yong muttered.

Gu Jun's heart was restless, and he saw the clue, "Amniotic membranes, it's amniotic membranes, we may be ...... Inside the womb of a black goat. ”
