Lin Yi and Director Liang didn't know how to comfort Teacher Zhang, so they could only follow each other silently and speed up. "Two experts, we'll be there soon. Our Principal Wang is in the dormitory area behind." After arriving at the main entrance of the school, Teacher Zhang Yumei, who was familiar with the road conditions, reminded Lin Yi and the others and quickened her pace. "Hey..." Looking at the two doorposts standing alone at the main entrance and the two large piles of buildings inside that had become small hills of ruins, Lin Yi and Director Liang sighed together and followed closely behind Teacher Zhang. Just after bypassing the first larger pile of ruins, Teacher Zhang staggered and crawled directly to the second smaller pile of ruins. In the middle of the ruins, with the messy flashlight light, several figures could be seen shaking... "Let's go!" Director Liang roared, limping and rushing to the ruins. Before he climbed to the middle of the waist, Lin Yi, who passed by him, had also surpassed Teacher Zhang and quickly arrived at the scene of the incident. "The doctor is here, make room!" "Watch your feet, be careful not to fall down..."
Seeing Lin Yi's monkey-like figure arrive, and seeing his white coat clearly, several young people hurriedly made room and guided Lin Yi to Principal Wang. While putting down the first aid kit, Lin Yi did not bother to check the injured and the surrounding situation. He immediately opened the injured's eyelids and used a flashlight to check the pupils. When the injured's pupils became larger and there were stress reactions left and right, up and down, Lin Yi's hanging heart was slightly relieved. Although the patient was already in a state of shock, the preliminary examination showed that at least he was still conscious... Then Lin Yi pressed his fingers on the injured's wrist and used the perfect level of medical consultation to first determine the various indicators of the injured's body at this time. "The victim's massive blood loss has led to ischemic cardiomyopathy, insufficient blood supply to the coronary arteries, and caused myocardial damage and fibrosis." "No damage has been found to other internal organs and the brain for the time being..." After quickly checking the victim's body functions, Lin Yi began to cut open the various layers of clothing wrapped around the victim's legs. "Doctor, don't dare to cut these clothes." "Principal Wang's leg artery should be ruptured. We have finally stopped the bleeding. If we cut it now, I'm afraid it won't stop the bleeding..." Seeing that Lin Yi was about to open the wound they had finally wrapped, a male teacher who knew a little bit of medical knowledge hurriedly dissuaded him. "It's okay, I have a professional way to stop bleeding." "Without removing the foreign objects around the wound, there is no way to determine the victim's injury." In order to avoid unnecessary misunderstandings and troubles, Lin Yi, who was constantly moving his hands, patiently explained a few words. "Both femurs are comminuted, the femoral artery is torn, the gluteus maximus and quadriceps are squeezed by heavy objects, and there is a possibility of rhabdomyolysis..." When the injuries on the victim's thighs were exposed, Lin Yi had to take a breath. A floor slab with a thickness of about 10 cm, a width of about one person's arms, and a length of at least three meters, hit the victim's thighs directly. There were three or four long steel bars on the left thigh, which penetrated the victim's entire thigh, causing the left thigh to be folded upward at a terrifying 150 degrees. The upper end of the torn femoral artery had been crushed to death by the floor slab, and only sporadic blood oozed out, which indirectly saved the victim some precious rescue time.
Judging from the situation, the blood on the ground should be caused by the gushing of blood from the lower limbs of both legs... [Tip: The patient's total blood loss has reached 1832ml, and emergency blood transfusion must be performed within half an hour, otherwise the heart is at risk of stopping at any time. 】 The precise amount of blood loss given by the system prompts Lin Yi frowned even more, and he suddenly felt extremely difficult. When the human body loses 800-1200ml of blood, it will cause mild shock, and the injured will have symptoms such as irritability, decreased blood pressure, cold limbs, reduced urine volume, and dry mouth. When the blood loss reaches 1200-1700ml, moderate shock will occur, the urine volume will further decrease, the systolic blood pressure will be mostly in Hg, the injured will be highly thirsty, the heart rate will accelerate, the heart rate can reach 100-120 times/minute, the expression will be indifferent, and there will be symptoms such as cyanosis of the extremities. If the blood loss exceeds 1700ml, severe shock will inevitably occur. At this time, the systolic blood pressure is usually lower than 60mmHg, the heart rate will exceed 120 beats/minute, and the injured may have obvious cyanosis of the lips and extremities, shortness of breath, impaired consciousness, and even coma... At this time, Principal Wang's blood loss has reached a terrifying 1832ml, which is obviously severe shock. If blood transfusion is not carried out in time, severe myocardial ischemia will occur, causing irreversible damage to the heart and even death. "The left leg is definitely not saved, and it must be amputated immediately." "If it is delayed any longer, rhabdomyolysis will release a large amount of toxic substances into the blood circulation, causing shock and renal failure, and the person will be completely hopeless!" At this time, Director Liang had come behind Lin Yi panting, and when he saw the condition of the injured person's thighs clearly, he decisively gave his first aid plan. When there are only two choices, saving life or saving legs, it is equivalent to having no choice... "There is no rush for amputation, Director Liang, has the rescue team's blood bank been established?" After hearing Director Liang's voice, Lin Yi immediately asked. Now we can only rely on the doctors of the health center to quickly deliver the required blood, otherwise everything will be in vain. "Not yet!" "The surrounding hospitals are all treating critically ill patients. The blood bank of the provincial blood center is in urgent need of blood. The temporary blood bank of the rescue team may not receive sporadic blood until tomorrow." "Can't we rescue the injured first and then consider other methods?" After talking about the situation of the temporary blood bank of the rescue team, Director Liang hurriedly gave his own plan. If the situation permits, sending the injured to the nearest hospital that accepts critically ill patients for follow-up treatment is the best option... "I'm afraid it's too late. The total amount of blood loss of the injured is estimated to be more than 1800ml." "If no emergency blood transfusion is performed within half an hour, it will be useless to rescue them." While responding to Director Liang, Lin Yi's mind was working even faster, considering whether there were any emergency alternatives. Regardless of the system prompt or the diagnosis confirmed by the perfect level interview technique, if the injured cannot get blood transfusion within half an hour, death is a foregone conclusion. But a good cook cannot cook without rice. Even if blood from the nearest hospital is mobilized, it will take more than half an hour to reach the disaster area... "The blood loss has reached more than 1800ml. What can we do?" "It is definitely too late to get blood nearby. Even if we find someone to donate blood for testing, it will take more than half an hour to go through the whole process..." Director Liang pulled his hair and turned around with his teeth bared. A normal person has only more than 4000 milliliters of blood in total. Principal Wang has lost nearly half of his blood. It is a miracle that he can survive.
Not to mention the half an hour estimated by Lin Yi, every minute that follows, there is a possibility of losing vital signs at any time... "I can only take a risk!" Lin Yi gritted his teeth and made up his mind secretly, and shouted at the people around him. "Who knows Principal Wang's specific blood type?"
