No matter how little medical knowledge he had, Teacher Zhang knew that the three elderly people in their sixties clearly did not meet the normal blood supply conditions. Shishan Town is economically backward and is a backward and poor area known throughout Long Province. Almost all the young and middle-aged labor force in the town went to other places and became part of the army of migrant workers in the city. Apart from the elderly and children left behind, the only people left in the town are some young and middle-aged women taking care of their families. The backward concept of medical and health care also makes many people who have never been to a big hospital spend their whole life not knowing what their blood type is. On the contrary, some elderly people over 60 years old found out what their blood type was for the first time when they went to the town health center for voluntary physical examinations for the elderly... Among the three lines in front of us, the shortest one is the one with blood type O. The slightly longer one, with five or six elderly people standing there, corresponds to blood types A, B, and AB. Basically composed of middle-aged women and young wives, this team of more than a dozen people did not know or could not tell their blood type. "Dr. Lin, is it harmful to the body to donate blood to people over 60 years old?" Knowing that it was even a bit cruel to do so, Teacher Zhang Yumei couldn't help but ask Lin Yi.
More than twenty people came to the scene. Who knew that the only three people in front of me who met the criteria were still old men in their sixties. God, weren't they obviously at odds with Principal Wang... "Doctor, don't listen to Teacher Zhao's nonsense about whether it will hurt your body or not." "Despite our age, our bodies are definitely strong after spending a lifetime digging in the fields." "Even those girls are not as tough as us..." Hearing Teacher Zhang ask the doctor this question, the two old men with type O blood at the scene became anxious. They rolled up their sleeves and patted their chests, just to prove that there was absolutely nothing wrong with their bodies. When they were first divided into teams, Teacher Zhang made it clear that Principal Wang had type O blood, and only the three of them were eligible for blood transfusions. The grandchildren of these people go to Shuguang Hope Primary School, and everyone is often favored by Principal Wang. Many children in the family are sick. If Principal Wang hadn't paid for medical treatment, it's hard to say whether they would have survived. Now that Principal Wang is suffering, if they don't even help with transfusion of some blood, then are they still considered human beings... "What's wrong with you ladies? Without us ladies, would you have any chance of growing up!" "If you know your blood type, you don't have to donate blood to Principal Wang!" "Doctor, just draw our blood and prepare what you don't need first..." The words of the two old men with type O blood were like poking a hornet's nest. The longest group of women pointed at the two and started scolding them. The intensity of their emotions and vicious words prevented the two old men from speaking back... "Hey...how did we end up with such a blood type!" "Principal Wang is such a good person, but he can't help at the critical moment." "Does this mean that we still have the face to face the principal in the future..." Only the five or six old people who knew clearly that they were not type O looked at the others with sad faces and sighed. I hate that my blood type is wrong and I can't help Principal Wang at all. "Quiet, everyone listen to me and you will have a chance."
"With our hearts in mind, I believe that Principal Wang will get through this." Seeing that the scene was becoming chaotic again, Lin Yi hurriedly spoke loudly to calm down everyone's emotions. Although the team with the most people was unable to determine his blood type for the time being, fortunately, the other party's words reminded Lin Yi in time and made him think of a workaround... "Teacher Zhang, I must first draw 100ml of blood with you and three elderly people with type O blood, and temporarily transfuse it into Principal Wang's body to prevent the injury from worsening." While taking out the blood bag from the first aid kit, Lin Yi called Teacher Zhang and the four of them to come to him. He skillfully inserted the needles into the median elbow veins of the four people's arms one by one, and asked everyone to clench and relax their fists so that blood could be drawn faster. Although the physical condition of Teacher Zhang and the three elderly people is not very good, only 100ml of blood needs to be collected, which will not affect the other person's physical condition. And the blood collection process will not leave Lin Yi's sight. If there is a problem, the system prompts will remind you in time... "Everyone, please stand a little further away to prevent blood contamination." "Don't worry, after I inject these four bags of blood into Principal Wang, I will come down to collect blood for everyone." Looking at the people gathered around and eager to donate blood, Lin Yi patiently explained his arrangement. These dozen women whose blood types are unknown are basically in their young and middle-aged years. Each person can collect up to 400ml of blood without putting too much burden on the body. Since there was no way to determine the specific blood type of the other party, Lin Yi had no choice but to collect 200ml of blood first. When it was time to transfuse Principal Wang, he would screen and collect additional blood at any time according to system prompts. As long as two or three of these dozen people meet the requirements, it should not be a big problem to stabilize the physical condition of the injured Principal Wang... "That's good, that's good..." "Thank you doctor, as long as it can help Principal Wang, it really doesn't matter if you smoke more..." After listening to Lin Yi's arrangement, the onlookers breathed a sigh of relief and hurriedly moved out carefully. "Doctor Lin, I think the needle method for blood collection is similar to that for infusion." "You have to believe me. When you go up to give Principal Wang a blood transfusion, I can help everyone draw blood first, so that time is not wasted." After watching Lin Yi's blood collection carefully, Teacher Zhang said confidently. Rescuing Principal Wang is a race against death. One less minute wasted will increase the chance of Principal Wang being rescued. "The school's funds are very tight. When students have a cold and receive an infusion, they are usually prescribed medicine. I help students with needles in the dormitory." In order to make Lin Yi believe that she has relevant experience in needles, Teacher Zhang hurriedly told her previous relevant experience...... "Okay, I will keep the blood collection bags in the first aid kit first. The amount of blood collected from each person must not exceed 200ml. Disinfection and hygiene must be paid attention to before blood collection." "After collecting blood from each person, find someone to send it up first." "Don't worry, the supporting doctors are on the way..." After instructing Teacher Zhang on some precautions, Lin Yi took the four bags of blood he had collected and went up to the ruins of the dormitory building again. Teacher Zhang will assist temporarily, which will save him from climbing up and down, saving precious rescue time.
As for the issues of health and safety, Lin Yi has also considered them. After finishing the first aid for Principal Wang, a comprehensive diagnosis will be made for the blood transfusion personnel to ensure that there is no possibility of cross infection during the blood collection process... "The ambulance will arrive in ten minutes, and the plasma urgently raised by the nearest hospital is also on the way. Try to arrive within forty minutes." "President Zang, accompanied by two teachers, will go to the path to meet the doctor of the emergency department." As soon as Lin Yi came up, Director Liang hurriedly reported the relevant telephone contact. "Lin Yi, why don't you wait a little longer, the plasma is on the way." Seeing that Lin Yi was about to give the injured a blood transfusion with a blood bag in his hand, Director Liang grabbed the other's arm in fear...
