It is a small world.

The "dripping dirt and dirt" ambulance rushed to the door of the emergency hall with its siren, and the idle male doctors led by Liu Tangchun stood in a row at the entrance of the emergency hall.

The white coat was swept up by the cold wind at the door, and Liu Tangchun and the others stood at the door of the emergency hall without saying a word. The expressions on the faces of the police officers and security guards behind him were somewhat helpless.

"Female, 67 years old, with severe burns on her back. There is a conscious disorder...... "The pre-hospital emergency doctor pushed the cart and was about to run to the emergency room, but as soon as he looked up, he was startled by the situation in front of him.

"Doctor, help!" said the middle-aged woman who had left the emergency room two hours ago was now in tears. She staggered out of the ambulance, her knees limped, and she sat on the ground.

Liu Tangchun nodded to the policeman behind him, "Please record the whole process." Then he made a color to the doctors beside him, and Sun Lien and others rushed up and pushed Zhao Weihong and the bed into the emergency room.

Liu Tangchun stood beside the middle-aged woman with another policeman, "Go register and pay the fee, Officer Wang will ask you a few questions." ”

Officer Wang nodded at the middle-aged woman, took out a notebook and a pen, and said, "It's important to save people, you go to register first, and then call your family to come here." How did the patient get hurt? Did he go to a clinic for fire therapy?"

Sun Lien is a little younger after all, and he is naturally indispensable for things like pushing the bed at the door. And Cao Yanhua and others have more than five patients on hand, and there is really no extra experience to admit such a serious patient. Sun Lien's treatment team, which had just been established for less than three hours, received the first case in this way.

"Zhao Weihong, female, 67 years old, suffered third-degree burns and fractured corpus callosum. On the top of Zhao Weihong's head, such a line of words appeared.

After taking a closer look at Zhao Weihong's appearance, Sun Lien noticed that something was wrong. Zhao Weihong, who was lying on her side on the bed, exposed her back - all her burns were concentrated on her back, and her entire back had been burned out of a large gray patch, and there were not even blisters on the burns. This indicates that the burns on her back have reached the most severe third degree - all the dermal cells under the burned area have completely died. And the musculature under the skin is likely to have been seriously damaged, to put it bluntly, Zhao Weihong's back is now in a state of burnt paste - the skin is carbonized, but it is unknown how much is cooked inside.

Burns are the most obvious and direct injuries, but what makes Sun Lien most vigilant is the state of rupture of the corpus callosum.

The corpus callosum is an extremely important structural tissue in the human brain. It is responsible for connecting the left and right hemispheres of the human brain. By exchanging information between the two hemispheres, and through the close cooperation of the two hemispheres, it is possible to form normal thinking skills, text reading skills, and so on. Even ordinary daily activities actually require the corpus callosum to be coordinated.

This important structure is located in the center of the brain, below the cingulate gyrus and above the thalamus. The corpus callosum itself is actually a large bundle of tenacious nerve fibers that runs horizontally. It is unlikely that this structural damage was caused by burns.

However, damage to the corpus callosum is not considered a life-threatening symptom, and it is not under the control of the emergency department for the time being. The current work of the rescue room is to save Zhao Weihong's life under extensive burns.

"Establish an advanced airway, an upper ECG monitor. Sun Lien commanded several nurses who came to help. usually has a sweet mouth and calls it sister, but now it shows its advantage. The nurses pushed the ventilator with their hands and feet, and Xu Yourong picked up the scalpel and pounced on Zhao Weihong's side, and after the nurses disinfected under her throat, their hands reached down and made an incision directly under Zhao Weihong's thyroid cartilage.

After separating the tissues and muscles above the trachea with vascular forceps, Xu Yourong took out the knife again and cut Zhao Weihong's trachea. Throwing away the scalpel with his hand, Xu Yourong grabbed the curved pliers that had been placed beside him a long time ago. With extremely rough means, he probed the curved forceps into the trachea, separated the trachea, and said to Sun Lien, who was preparing to be next to him, "Intubation!"

Sun Lien inserted the trachea into the incision, and then pulled out the die in the ventilation tube. Xu Yourong loosened the vascular clamp and curved forceps, and began to fix the catheter with the assistance of the nurses.

"Ask the burn surgeon to come and consult. Sun Lien took two steps back and looked at Zhao Weihong, who was lying on his side on the hospital bed. The nurses had already attached the ventilators to the ventilation tubes, and the status bar was not showing anything new. It is still a rupture of the corpus callosum and extensive burns.

"Establish intravenous access, at least five. After a little thought, Sun Lien gave a new order to the nurses. "Thank you, please have a supper tonight. ”

ECG monitoring is finally working. Zhao Weihong's condition is quite critical, with a heart rate of 144 beats per minute and a blood pressure of only 85/55. This is a typical symptom of shock after a severe burn. As a result of the body's natural reaction, a large amount of bodily fluid leaks out near the wound. As a result, burn patients develop severe volume depletion – the body's largest water reserve, which is actually blood.

When blood volume decreases, the total amount of blood flowing in the blood vessels naturally decreases a lot. This causes the body's blood pressure to drop rapidly, and in order to compensate for the lack of blood circulation caused by low blood pressure, the heart begins to beat like crazy, trying to pump more blood to the rest of the body to sustain life.

At this point, the most important thing is to establish the intravenous access needed for large volumes of fluids as quickly as possible. If necessary, the tibia can even be punctured directly for fluid rehydration. But it is a little difficult to hand over these tasks to the nurses - Zhao Weihong, who has lost a lot of body fluids, almost all of them are shriveled, although the nurses in the emergency room of the Fourth Central Hospital are all experienced in battles, and they are still a little helpless in the face of the shriveled veins in the limbs.

"The anesthesiology doctor will be there shortly. Xu Yourong corrected Sun Lien's order beside him, "Wait for the anesthesiology department to do the jugular vein infusion rehydration, and the limb rehydration is of little significance now." ”

"Prepare the crystalloid ......" Sun Lien quickly calculated the amount of fluid that the patient needed according to the formula in his mind, "Contact the blood bank, first adjust 500 ml of ......plasma," he glanced at the heartbeat that was still rising, "Adjust 1,000 ml of balance solution." Add another fentanyl and pump it at a total of 20 milliliters with a flow rate of one milliliter per hour. ”

Fentanyl is a strong analgesic controlled class with 80 times more analgesic potency than morphine. For burn patients, what they need most is not debridement or anti-infective therapy. Rather, it's this powerful analgesic.

The pain caused by extensive burns can directly cause a mental breakdown.
