"What's wrong with this person?" Tan Ying was startled by the bloodied appearance of the injured.

The zoo staff did not stop at their feet, carrying the injured person as he ran, and replied: "He is the keeper of the black bear house, and when the black bear escaped before, he tried to drive the black bear back, but he was attacked and bitten all over his body." It was also when we had just sent the black bear back to the museum that we found him lying in a pool of blood and dying......"

"How long does it take you to go to the hospital like this? I'll help you call a police car in and take him to the hospital!" Tan Ying hurriedly picked up the walkie-talkie and contacted the police who were maintaining order outside the zoo.

After Li Sichen looked at the face of the injured man, he suddenly shouted: "Put him down, quickly!"

"Why?" everyone was stunned.

Anyone can see that the injured person is in very serious condition at the moment. If you can't get to the hospital as soon as possible, your life is likely to be in danger. In this race against time against death, how could Li Sichen make such a request to delay time?

Even Tan Ying couldn't understand Li Sichen's intentions, frowned and said, "The condition of the injured person is so serious, can't you delay time......"

Li Sichen interrupted her words and said in a deep voice: "It is precisely because of the seriousness of the injured that I asked them to put people down! You see, the injured person is not only unconscious, but also has cyanotic lips, fast and weak nasal wings, pale and gray face, and the veins in his neck are also in a state of anger. All this shows that the injured person is in a state of breathlessness and hypoxic shock at the moment! If you take him to the hospital like this, I am afraid that he will die halfway through!"

"What?"

"So serious?"

Everyone was frightened by Li Sichen's words.

No one doubts whether he is alarmist, on the one hand, the ability and style he has shown before have been affirmed and admired by everyone. On the other hand, it is the situation of the injured at the moment, which is completely in line with Li Sichen's description.

Tan Ying hurriedly said: "I remember that you know medical skills, is there a way to treat this injured person!"

Li Sichen replied: "I told the injured person to be put down, just to give him first aid. ”

The zoo staff hurriedly put the bed board carefully on the ground.

Li Sichen squatted beside the injured and quickly checked the situation: "There is no foreign body in the injured person's mouth, and there are multiple bite wounds on his body, of different sizes and shades. Especially in the upper body and chest, there are many wounds. It is these chest traumas that allow the pleural cavity to come into direct contact with the outside atmosphere, causing developmental pneumothorax! Symptoms such as dyspnea and even shock are all caused by this!"

This description of the condition made everyone listen to the fog and fog, and they couldn't help but have a little more confidence in Li Sichen.

"What kind of pneumothorax is this, and how to treat it?" Tan Ying asked with concern.

"It is necessary to puncture the pleural cavity to decompress and relieve dyspnea. Otherwise, it won't be long before the injured person dies due to lack of oxygen! He is now in shock due to hypoxia, and the situation can be said to be very serious!" Speaking of this, Li Sichen raised his head and asked the surrounding zoo staff: "Are there any syringes and adhesive tapes in your zoo?"

"There's a syringe in the vet station, right next to here, I'll go get it. A zoo worker immediately responded.

"TO BE A LITTLE LARGER, AT LEAST 50ML OR MORE. Li Sichen admonished.

"Understood!" the man replied as he ran, "The syringes in our zoo are all big. ”

At the same time, another zoo worker said, "There's duct tape in my place of work, I'm going to get it." ”

When the two of them went to get something, Li Sichen was not idle, first took out a silver needle, and pricked a needle in the Suji acupoint in the center of the tip of the injured person's nose, as well as the Neiguan acupoint on the center of the horizontal stripe on the inside of the two wrists.

The Suji acupoint and Neiguan acupoint have the effect of correcting and relieving adversity, which can alleviate the situation of the injured who have difficulty breathing and are dying at the moment.

In addition to pricking needles, Li Sichen also took out gauze, hemostatic powder and other items from his shoulder bag.

He handed over the hemostatic powder to Tan Ying and instructed him to apply it to the wounds around the injured person to stop the bleeding and build muscle and relieve the danger. He himself, on the other hand, was holding gauze and wrapping it around the wounded man's chest, causing an open pneumothorax.

It was at this time that the zoo staff who had gone to get the tape ran back out of breath.

After taking the tape, Li Sichen immediately wrapped it around the outside of the gauze, circle after circle, until the entire gauze and even the side area were covered.

"Why do you have to wrap adhesive tape around the gauze?" Tan Ying asked puzzled. She also learned some simple first aid techniques, including how to dress wounds. But there is no mention of using adhesive tape......

Li Sichen explained simply: "I wrapped a layer of adhesive tape around the gauze in order to achieve a closed effect, so that the open pneumothorax becomes a closed pneumothorax. ”

In fact, he wrapped a layer of adhesive tape around the gauze, which was also a helpless move. After all, there is no other material in the hand, and if you use gauze alone, there are many mesh holes on it, which is easy to breathe, and it is difficult to achieve the desired sealing effect.

Not long after the gauze was wound, the syringe was also taken, which was the 50ML syringe requested by Li Sichen.

After receiving the syringe, Li Sichen immediately inserted the needle above the wound that caused the open pneumothorax, passed through the edge of the ribs, and entered the pleural space.

According to the normal requirements of paracentesis, it should be performed with a puncture needle. But there was no such device in the zoo, so it could only be used directly with the needle of a regular syringe.

After the puncture was successful, Li Sichen immediately twitched the core rod and decompressed. Because the needle of an ordinary syringe is smaller than the caliber of a puncture needle, the difficulty of pumping and decompression is also much higher. Fortunately, Li Sichen's strength is strong enough and his hands are stable enough, otherwise, it would not be easy to pull his qi out.

Soon, the syringe was full of gas, Li Sichen removed the needle, exhausted the gas in the cylinder, and then put the needle back on for a second pumping. After going back and forth several times, the pressure inside the chest cavity of the injured person gradually decreased, and the originally difficult breathing was greatly relieved.

After making sure that the injured person's breathing had returned to stability, Li Sichen stopped pumping and decompression, and ordered the zoo staff next to him: "He is out of danger, but he still needs to receive regular treatment, hurry up and send him to the hospital!"

"Thank you, thank you!"

After expressing their sincere gratitude to Li Sichen, the zoo staff lifted the injured man again and sent him to the police car that had just arrived, and took the police car all the way to the hospital.

Li Sichen didn't care about resting, and beckoned Tan Ying and said, "Let's go, let's go to Nanshan!"
