Until Wang Ge arrived at the scene of the accident he had seen with his own eyes, he didn't have time to glance at the messy news on his mobile phone.

He didn't know what was going on the network, but he knew what was going on at the scene.

Now, fire trucks have arrived at the scene, and rescuers have begun to rescue the scene.

The truck driver was unconscious before the crash and had no vital signs before the ambulance arrived at the scene, and the doctors did not know exactly what the man died and how it caused the serious accident, but they did not put much effort into him.

If something has happened, then we can only do as much as possible to remedial what has happened and minimize the impact, rather than finding out what the cause is and determining who is responsible.

And most netizens are very urgent about the process of things. A lot of people's intellectual curiosity makes them really want to know what this is all about, what is going on, and why it is happening.

However, no one can give an answer until the matter is dealt with. Everyone is busy saving people, and only after saving can we conduct an investigation and give you an answer, who has time to pay attention to your irrelevant curiosity and curiosity now!

Health care workers are consequentialists through and through. Anyway, the result is either life or death, no matter how much effort they put into the rescue process, only if the patient is alive, people will recognize the value of the doctor's rescue, if the patient dies, even if it is too much, as a doctor, they will think that their rescue is a failure.

They don't care about the cause and process of the matter, they only care about the life and death of the patient.

In addition to the ambulance from the Second Affiliated Hospital of Yaxiang, other hospitals also sent vehicles to reinforce and hit several private cars on the truck, the driver and passengers on it were not too seriously injured, the doctors just treated the wounds briefly, and then immediately took the person away from the scene.

The main task of the firefighters was to rescue two adults and a child who were still crushed under the truck.

The truck is empty, but fortunately, it is empty, otherwise these people under the car will definitely have no chance of being saved.

When the vehicle turned and hit the sidewalk, several pedestrians could not dodge, some were scratched and fell to the ground, some were hit by the front of the car, and the worst belonged to these three people, who were caught under the body.

The front axle of the truck has been broken, the wheels flew out directly in the process of impact, the chassis of the front half of the front half of the car is in direct contact with the ground, and the tires behind the truck are lifted, forming an angle.

And those three people were pressed by the front of the car, the gap was relatively small, and ordinary jacks really couldn't be put down.

After all, this is a truck, the tonnage is relatively large, even if everyone at the scene works together to lift, the front of the car is not moving, in fact, at the beginning of the accident, there were enthusiastic people at the scene who tried it.

The two adults are not relatives or friends of the children, in fact they do not know each other, but they suffer the same pain and fate.

A middle-aged man, and the child's head is facing outward, the middle-aged man is pressed against the abdomen, but the child's legs are compressed.

The two of them were quite conscious, and their emotions were relatively excited, and their expressions were very painful.

Another middle-aged woman was lying face down on the ground, her back was pressed by the front of the car, and her head was facing the inside of the front of the car, but she was motionless at the moment, and she did not respond to her shouting.

The child is about thirteen or fourteen years old, originally the parents said that the child had a little fever, stayed and went to the clinic to take a look, there was no big problem and asked for leave to go home to rest, but I didn't expect to encounter this kind of thing on the way home.

Now the child's parents have been pulled out of the fence, with tears in their eyes, and they keep looking inside.

"I'm afraid this woman won't be able to do it. Cao Shan said to Wang Ge and the doctors from other hospitals on the scene. He seems to know this doctor.

"Yo, Mr. Cao!" The man looked up and actually recognized Cao Shan, "I don't have blood pressure, I can't feel my pulse, and I can't breathe." The doctor next to him nodded. "We tested it just now. These two people are okay, and the women are enough to choke. ”

He was also waiting here, and when the people under the front of the car were rescued, he immediately began to rescue and brought them back to the hospital.

"Let's go over, some medicines can be used in advance. Cao Shan seemed to think of something, patted the king pigeon on the shoulder, and walked to the front of the truck.

The medical team from other hospitals also followed Cao Shan and Wang Ge over with them.

"Save the child first. When the middle-aged man saw Cao Shan coming, he hurriedly said, but his voice was a little small.

Cao Shan smiled, which can be regarded as relieving the atmosphere of the scene. "It's not a TV series, it must be the two of you who saved it together!

"Everything else is fine, but my chest is tight, I can't breathe, I can't move my lower body, but I still have consciousness. I want to smoke, driver, do you have a cigarette there? This middle-aged man spoke playfully and looked very open-minded.

"This is the scene of the accident, and fireworks are strictly prohibited. In case of oil leakage, we will all go to heaven to ignite the fire. Smoking is bad for your health, and you can't die yet. The king pigeon hurriedly said.

The man was lucky, he didn't feel too much wrong, internal bleeding, organ contusions, and the metal beam of the truck pressed against the softer parts of his body, and the damage was not so great.

In addition to this, the person had only a few abrasions on his body. Even if it's internal bleeding, it's not that serious.

On the other hand, the child next to the middle-aged man was a little frightened and speechless. The middle-aged man glanced at Wang Ge and Cao Shan, in fact, he was also easing the atmosphere just now, afraid that the child would be too frightened, and something would have happened if he was fine.

But this kid didn't say a word, which is quite worrying.

"Brother, how do your legs feel?" Wang Ge squatted down, "Manly man, don't be afraid, the firefighters will rescue you later." ”

"It hurt at first, but now it's numb, and I feel ...... It's a little cold. The child's immature voice trembled a little, "I heard that such a leg has to be amputated, I don't want to have no legs......"

"No, it's only been a long time! Wang Ge hurriedly comforted, then took out his mobile phone and glanced at the time, it should have been about half an hour since the car accident.

The child's legs were pressed and blood flow was poor, and if the compression was too long, it would definitely cause tissue cell necrosis.

A dead limb is like a piece of scrap flesh growing on a human body. After it is inactive, it will begin to decay, and various toxins will enter directly from the body's blood circulation, causing a variety of very serious complications.

If a tourniquet is used to stop bleeding in the limbs, if you want to prevent limb necrosis without affecting normal blood circulation, then at least once every hour.

It's been more than half an hour now, and it seems that the time is still in time.

Although the child's words were not long, they still brought Cao Shan three very useful information.

First, the blood circulation in the child's legs has been severely affected.

Second, although the feeling of pain has changed to a feeling of numbness, and it feels a little cold because of poor blood circulation, at least the child's legs are still sensitive. If you get people out now, it seems that these legs can still be saved.

Third, although the prime time is within an hour, that is for adults. Children are not fully developed, and their blood vessels are thinner, so they may be more fragile than adults. Poor blood flow for just 40 minutes can lead to limb necrosis.

You must know that this kind of pressure is theoretically much stronger than the blockage effect of blood circulation than that of a tourniquet.

Wang Ge grabbed a passing firefighter, "Comrade, how long will it take to get people out?"

The firefighters were busy with their feet not touching the ground, "Now the jack doesn't work, we have contacted the crane, and we are calculating the key points, tying the rope first, and then the car will come to try for a success." But if you have to wait for the bus to come, it will take about 15 minutes. ”

"Fifteen minutes, that's close to fifty minutes? Dr. Cao, in this case, you have to consider crush syndrome, right?" said another doctor.

Cao Shan nodded in agreement.

The catastrophe of the 2008 earthquake is still fresh in our minds, and the Chinese people have united to fight the earthquake and provide disaster relief, and finally work together to overcome the terrible natural disaster.

The ruins have been transformed into new towns, and the souls of the dead seem to have been laid to rest.

But in the midst of that disaster, many rescue problems were exposed.

Since most of the people involved in the disaster relief are armed police or soldiers, and do not have the corresponding medical knowledge, there are so many medical workers on the scene, which is also a helpless thing.

Moreover, in terms of disaster first aid, the traditional medical emergency knowledge also has shortcomings.

The rescuers stayed up for several days and dug up countless dead people, and suddenly found a wounded person who had been buried for more than ten hours under the rubble, and this person was still alive, and they immediately became excited.

Medical workers give oxygen, check the body, replenish nutrition and energy, and see that this person will become the next miracle to inspire.

When the casualty was finally dug out of the waste, the stones that had been pressed on him were removed, and the casualty was transferred to the medical station, within ten minutes the casualty had died of sudden acute renal failure and severe metabolic acidosis.

It was only then that the medical staff realized that it was crush syndrome.

As the name suggests, crush syndrome is generally a sequelae caused by severe and long-term squeezing of the human body, especially the limbs.

In the case of heavy compression, blood circulation is blocked, muscle necrosis, a large amount of myoglobin and potassium in muscle cells enter the blood vessels of the compressed and necrotic tissues, in addition to this, there are substances such as phosphate and sulfate.

In this way, the oppressed part becomes a gathering place of poisonous blood.

As soon as the weight is suddenly removed, blood circulation is restored, and this part of the blood, which contains a large amount of myoglobin, potassium, and acidic substances, immediately rushes to the whole body and enters various organs.

Myoglobin can cause renal dysfunction and even failure, high blood potassium can not be excreted through the renal circulation, and can soon reach a lethal dose, in high blood potassium at the same time as high blood phosphorus, magnesium, low blood calcium, increase the pressure and toxicity of the heart, there is a risk of cardiac arrest.

Not to mention acidosis, which can cause confusion, nausea and vomiting, and even multi-organ failure.

In the earthquake, it was pressed for more than ten hours or dozens of hours, and the blood accumulated more in the necrotic limbs, even if active prevention was carried out, or even a decisive amputation on the spot, the chance of survival was not large, this is just an extreme special case, and the time of being pressed is too long, so it can cause death within ten minutes.

Generally speaking, although crush syndrome comes quickly, it does not kill so quickly, and it usually gives people a chance to prevent and rescue.

For example, these two patients today.

Now the two doctors are not thinking about how to prevent the child from crushing syndrome, but about saving his legs as much as possible.

Once there is severe limb necrosis, gangrene, even if there is no crush syndrome, it is necessary to amputate the limb.

And the middle-aged man's condition is not optimistic, he said that he couldn't breathe was not a joke, and after a while, his face was a little pale, and his lips were purple, it seemed that his lungs might have some damage. Either hemopneumothorax or contusion.

"Oxygen, ECG monitoring, give me a blood oxygen concentration. Cao Shan was already thinking about thoracentesis for the middle-aged wounded.

"Open the meridian channels, give mannitol, furosemide, saline supplementation, five percent sodium bicarbonate intravenously, I don't have glue here. Another doctor looked at Cao Shan.

Cao Shan also shook his head, usually you don't have this thing in the car.

"Later, we have to cooperate well, first block the blood circulation, as long as the front of the car comes together, the person will be dragged out and immediately carry out the fascial septum incision and reduction. Cao Shan agreed with the doctor's advice.

"Xiao Wang, go buy some ice water, preferably ice cubes, wrap it in gauze, and apply a cold compress later. Cao Shan said to the king pigeon again.

The king pigeon immediately agreed, and ran to the side of the road to buy it, and the shopkeeper didn't confiscate the money at all when he heard about the use, and let the king pigeon take whatever he wanted.

Wang Ge was happy to see people, but he was not polite, took a few bottles of ice water and turned around and left.

A few minutes passed back and forth, and the crane came faster than the king pigeon thought. The preparation of the firefighters has already been completed, they carefully selected several points on the front of the vehicle, fixed them with fire ropes, and then tied the ropes to the mechanical arm of the crane to ensure that when the mechanical arm is lifted, the entire front of the vehicle will leave the ground at the same time, and will not let a certain place be stressed alone, only in this way can the greatest possible guarantee that the patient will not be injured twice.
