   An old man walked in front of him and couldn't dodge, and was hit by a tricycle. The old man fell to the ground without saying a word. What was even more frightening was that the tricycle hit the old man and then hit the wall. It rolled over on the spot, and the uncle riding the tricycle fell from the car and fell to the ground motionless.

   The sudden accident left all bystanders stunned. Immediately after her reaction, Xie Wanying found out that she and the monitor were the only people who saw the accident.

   Without saying a word, Xie Wanying ran to the injured person.

  Yue Wentong saw her running back more than ten meters away, and then he remembered that he was going to take a step.

   "Ah ah ah!" The old man gasped in pain, screaming in pain.

  There are no street lights at the end of this alley at night, no wonder there was such a serious car accident just now.

   Quickly took out the flashlight from the bag, Xie Wanying turned on the light and shot it at the old man and the uncle on the tricycle in the distance.

   Yue Wentong, who was catching up, didn't expect that she even had a flashlight on her body, and a look of surprise flashed in her eyes. Who would think of carrying a flashlight in their school bag every day?

   Relying on the powers stimulated in the body, Xie Wanying quickly judged the severity of the two wounded.

  The uncle hurt his head, and the old man hurt his thigh.

  If the head injury is to be treated, an electric drill is needed to drain the skull. She does not have this device in her hand for the time being, and the development of the brain injury is not as fast as the thigh injury of the elderly at this stage.

  The old man's leg injury is expected to be a ruptured femoral artery.

  If the thigh is injured and the aorta is injured, it is a massive hemorrhage, and the blood of the human body can quickly lose more than half of it, resulting in death from hemorrhagic shock.

   The first principle of on-site first aid treatment is not to save which one is seriously injured, but to comprehensively consider according to the on-site situation, which one needs more and can get on-site rescue first, and the two need to be weighed.

   "Deal with this first!" Xie Wanying made a decisive decision, squatted down beside the old man, and said to the monitor opposite, "Give me all the gauze bandages you bought, hurry up!"

  Yue Wentong looked at the uncle of the tricycle lying still on the ground in the distance. He only felt that it was more serious, and replied, "I'll go see that uncle."

"It's useless if you go to see him. He has a traumatic brain injury, and you can't do anything with it. It won't be too late to take him to the hospital when other people come over." Xie Wanying said, "In a few minutes, saving the old man is more important. ."

   "How do you know?" Yue Wentong asked her.

Before I could go into details, Xie Wanying snatched the plastic bag from the grocery store in his hand, took out the bandages and gauze inside, quickly stacked the gauze, put the bandages on, and pulled the rest of the bandages away. Use the surgical scissors you just bought to cut the head of the bandage. Ready to bind.

   Her series of quick and neat movements made Yue Wentong dumbfounded. He bought these things to keep in the dormitory as a spare, but in terms of how to use them, he only used them in the hospital when he saw a doctor.

   "Is your dad really a truck driver?"

  Yue Wentong's solemn questioning sounded under the night.

   The doubts about her seem to have been known to her from the beginning. Like the other boys in the class, he heard that there was a girl who came to study in their class. She was the champion of science. She had a quiet and elegant appearance. No matter how you looked at it, she looked like a girl who studied liberal arts. How could he be selected to study surgery? No one Makes sense.
