The scene of the car accident was a mess.

The dark green bus flipped on its side, and the front of the bus had been hit and dented in a large chunk. The green paint rubbed off the trail, some green, some white, and some strange black marks. The smell of diesel fuel was in the air, and all the glass on both sides of the bus had basically turned into granules and scattered on the asphalt floor of the highway.

When Sun Lien rushed to the side of the bus, he happened to see a little boy climb out of the window. He looked like he was about five or six years old. The face was scratched by the glass a few times, the wound was not deep, but the small face was a little pale. A middle-aged man was holding the little boy's buttocks and trying to lift him out of the window.

Sun Lien tried the test chassis with his hands, and a steel pipe that he didn't know what it did. The tube body is quite sturdy, and the temperature is not high. It's a little lukewarm to the touch. With the help of the steel pipe, he barely climbed onto the side of the car and took the little boy from the middle-aged man.

There is no time for a diagnosis right now, not even for a closer look. Sun Lien turned around and handed the child into Hu Jia's hands, then turned his head and climbed into the bus again. He believed that Hu Jia would be able to handle the situation. The casualties in the car were unclear, and the child looked in need of help, but he didn't have time to comfort an injured child right now.

"Help ......" There began to be a burst of wails in the car, some crying, some crying out in pain. After observing the car window, Sun Lien leaned on the side of the car, stretched out his hand downward, grabbed the hand of a middle-aged woman, and tried to pull her out.

It's not a way to go on like this, it's too slow. Sun Lien began to be a little anxious, and his position was on the left side of the bus. The wide bus lies directly on the highway, and the body of the car on its side becomes a cliff about two meters high. Although the seats in the car body can be used as stair treads, it is too much time to drag people out one by one. What's more, if someone has a broken bone, this method of evacuation can be extremely difficult, and it can also lead to more serious injuries during the climb.

Sun Lien bypassed the broken window, stepped on the emergency exit door next to the car to the roof of the car, and then jumped out of the car.

On the roof, there are two roof escape windows. Sun Lien twisted the handle on it vigorously and pulled the escape window hard.

Several young people who were not too seriously injured came out of this escape window, and as soon as they got out of the car, they were dragged by Sun Lien.

"How many people are in the car?" Sun Lien didn't care about his attitude now, he was almost shouting at the young people in a hurry. "Are there any serious injuries?"

"There are about a dozen of them. The young man who was dragged by Sun Lien seemed to have a cut in his eyebrow, but the bleeding speed was not too fast. Dark red blood dripped down his face, and he looked a little scary. "I don't know the injury, it seems that a few people were lying in the car just now and didn't move!"

"Go and wait outside the guardrail!" Sun Lien pointed to the highway guardrail behind him, "There is a doctor in the black car behind, you go to the black car!" As soon as he finished speaking, he lowered his head and got into the car.

The situation in the bus was a mess. The young men were probably wearing seat belts, but they were only slightly injured. As soon as Sun Lien climbed into the carriage, he was startled by the tragic situation in front of him.

At a glance, the status bar was directly filled with Sun Lien's field of vision. The three injured people lying in the window on the right side of the car have stopped moving. The status bar directly and simply displayed three words on the heads of these three people, "Dead". Sun Lien took a general look, and the three of them probably hit the ground directly when the vehicle rolled. The victim who died the most was gone, starting from the head and continuing to the position of the third thoracic vertebrae. Combined with the black marks that Sun Lien saw at the beginning...... I'm afraid that when the bus rolls, his upper body will be thrown out of the car. Then it was ground into a pulp by the body and the asphalt road.

The other injured people in the car who were still able to move began to gradually regain their movements, and they pushed open the safety door on the left side of the bus with difficulty and slowly. Unfortunately, because of the height, only one person climbed out. And the rest of the people climbed out through the roof escape door that had been opened amid Sun Lien's shouting and guidance.

There was also a middle-aged man lying by the window, staring wide-eyed and silent, and a young woman with an apparently broken femur in her left leg. The woman looked okay, Sun Lien glanced at her status bar, the femur of her left leg was fractured, the left foot was dislodged, the left arm was fractured, the fourth, fifth, and sixth ribs were fractured, and there was also an open pneumothorax.

These injuries are all first-level serious injuries even if they are placed in the emergency room, but compared to the middle-aged man, her injuries are really "okay".

"Song Hualin, male, 49 years old, fracture of the pivotal vertebrae, thoracic vertebrae, lumbar spine dislocation. The three symptoms on the top of the middle-aged man's head flashed, and Sun Lien only glanced at it, and felt a cool breath coming out of his back.

Any one of thoracic fractures and lumbar spine misalignment in a car accident injury will attract the attention of almost all doctors in the emergency room. If there are two concurrent incidents, in the Fourth Central Hospital, Director Liu Tangchun will personally be present to direct the rescue. But that's about it. Such an injury is serious, and high paraplegia is almost certain. But as long as the patient's vital signs are stabilized, saving his life is not a big problem.

But Song Hualin also has the symptom of a vertebral fracture.

The pivotal vertebrae are the second vertebrae of the human spine. The pivotal vertebrae are joined together by the odontoid process and the odontoid fovea of the atlas vertebrae, connecting the base of the skull with the rest of the spine. The odontoid process, which is responsible for connecting the pivotal vertebrae and the atlas vertebrae, was originally supposed to be the vertebral part of the atlas vertebrae. However, during development, it detached from the atlas and fused with the pivotal vertebrae.

As the hardest vertebral bone in the human body, the pivotal vertebrae are of great significance to the human body. This section plays the role of "connecting the upper and lower parts", and at the same time protects the vertebrae at the caudal end of the medulla, once a fracture occurs, the vast majority of patients will die at the moment of fracture. The medical community generally believes that the mortality rate of 15% of vertebral fractures in clinical statistics is seriously underestimated. These patients who were able to come to the hospital for imaging tests and were finally diagnosed with a vertebral fracture were actually lucky survivors.

During Sun Lien's 14 months of internship and regular training in the Fourth Central Hospital, he only saw one case of a patient with a vertebral fracture who was sent to the hospital for rescue. At that time, the patient was admitted to the Fourth Central Hospital because of an accidental fall from the building. Within five minutes after the imaging department confirmed a burst fracture of the pivotal vertebra combined with neuraxial dural hematoma, Zheng Guoyou and Liu Pingchuan rushed to the emergency room. At the same time, the two also brought almost all the backbone doctors in their department for a comprehensive consultation. Within fifteen minutes, the directors of the emergency department, imaging department, anesthesiology department, intensive care medicine department, neurosurgery department, and orthopedic department were all in place. In the end, everyone came to the conclusion of only one - emergency surgery must be performed immediately. Zheng Guoyou and Liu Pingchuan are pessimistic about the success rate of emergency surgery. Both argued that the procedure was life-or-death — that the patient's condition was too dangerous, and that the likelihood of dying from compression of the caudal medulla oblongata on the operating table was too high.

Outcome...... In the end, the patient was not able to go to the operating table and gambled on whether his life was good or bad. When the medical staff in the emergency room were about to transport him, his breathing and heartbeat suddenly stopped. With the help of a ventilator and an automated chest massage AutoPulse device, the patient was confirmed dead after an hour-and-a-half-long resuscitation.

With the assistance of six department heads, the rescue still failed. And in this kind of place where there are almost no rescue resources, Sun Lien saw such patients again. This made his heart feel cold, and the beads of sweat on his back almost instantly wet the clothes he was wearing.

"Dr. Sun!" was as Sun Lien was thinking about the treatment plan, and Dr. Pascal's shout sounded outside the carriage. "Are you still in the car?"

"Dr. Pascal!" Sun Lien realized that he was not fighting alone now. Of the seven people in the MPV, there were three doctors and one nurse. "I found two injured people, both of them are in serious condition, have you called the police?" After speaking, Sun Lien walked towards Song Hualin. "I'm a doctor, and I'm here to save you. Now please follow my instructions, stay relaxed, and never move. ”

Song Hualin said "yes" in a moaning voice. After Sun Lien walked to the position above his head, he half-squatted down, took off the down jacket on his body, picked up a few clothes and plastic water bottles scattered in the car, and put the plastic water bottles parallel to Song Hualin's jaw and collarbone, and carefully moved Song Hualin's neck in the way of "head lock" according to the operation process. I put the down jacket underneath and tied it up with the plastic water bottle.

"Your situation is not very clear, and I am worried that there may be a problem with your cervical spine. Sun Lien reassured while dealing with it, "In order to prevent the injury from changing, I have to wait until the fire brigade arrives to carry you out." "When rescuing in an emergency, it is easier to get the cooperation of the injured person by explaining the current situation and how you deal with it. If you just keep your head on your head, it may make the injured person feel emotionally excited again.

After briefly dealing with Song Hualin's cervical spine problem, Sun Lien, who had the remaining thoracic and lumbar spine injuries, did not deal with it for the time being - the middle-aged woman behind her had a condom injury, and if she didn't deal with the unbearable pain and continuous blood loss, she might die. And compared to blood loss, she now has a bigger problem with open pneumothorax.

Sun Lien leaned over to the middle-aged woman, "I'm a doctor." You ask you to lie down and not make any movements. He glanced at the middle-aged woman's neck, and the trachea was clearly deviating to the left. This indicates that the pneumothorax occurred in the right lung, and that the right lung is no longer functioning.

Sun Lien tore open the clothes on the middle-aged woman's body, and soon saw a bare bone in her right rib. There was a "hissing" sound at the wound.
