He Xiangyu looked back, and when the junior sister was saving someone, someone wanted to pull the sleeve of the junior junior sister, warning loudly: "The doctor is saving people, don't get in the way, stand aside!"
Several people immediately obeyed the order and retreated obediently.
Liu Jingyun couldn't hold down the bleeding part of the young man with a towel, and the blood continued to flow out. Knowing that she couldn't handle it with her own strength, she made a judgment and said to the second junior sister: "Go and do heart compressions for Yingying, let her come over. !"
Turning around and running, He Xiangyu rolled up her sleeves and came to the side of the little junior sister, pushed the little junior sister away and rushed up to press, calling the little junior sister: "You go to the senior sister, I'll come here!"
"Second Senior Sister, you have to keep pressing her, she has suffered a cardiac arrest, there is a chance—" Xie Wanying said to her senior sister.
"I know, I know, I won't stop if you don't tell me to stop!" He Xiangyu mustered up all his energy, planning to press desperately, pressing on the old man's chest hundreds of times a minute.
The patient was handed over to the second senior sister first, Xie Wanying ran back to the senior sister and asked, "What's the situation?"
"The bleeding can't be stopped!" Liu Jingyun pressed the patient's bleeding part so hard that her hands were about to tremble, and her voice trembled.
"Move away a little, and I'll see where the bleeding is." Xie Wanying said.
Liu Jingyun was not very confident, the moment she slowly moved her hand and the towel away, the bloody and bloody wound was exposed, and she couldn't help covering it with the towel.
People around me covered their faces and eyes, but they didn't dare to look at it: it was too scary!
At this time, only the surgeon would definitely dare to see it.
Let the big sister move her hand away, Xie Wanying carefully inspected the wound in detail, and must first distinguish what the wound is. Violent trauma to the head from an impact can be called traumatic brain injury or craniocerebral trauma or traumatic brain injury. Craniocerebral injury is divided into scalp injury, skull injury, or brain injury in the skull. Now, whether this patient is one of them or a combination of the three injuries needs to be initially identified.
The patient's pupillary reflex was present, but no abnormalities were found. It can be preliminarily determined that there is no intracranial brain injury. The human skull is hard, and it is not very destructive, so it is impossible to cause skull damage. So, most likely just a scalp injury.
Don't underestimate the scalp injury, because the human scalp is rich in blood vessels, and the amount of bleeding will suddenly be large, which will cause the patient to go into shock.
The patient's blood pressure dropped, and he showed symptoms of pale complexion and lips. It is right to stop the bleeding immediately. It's just that hemostasis on the scalp is not the same as hemostasis on the skin in other parts.
The scalp is divided into five layers. Scalp injury bleeding occurs in the subcutaneous tissue layer instead of the skin layer. The abundance of human scalp blood vessels refers to the many blood vessels separated by fibers in the subcutaneous tissue layer. The blood vessels under the skin of the scalp cannot be contracted by themselves, so there is a lot of bleeding. If compression cannot stop the bleeding, in addition to suturing, it is necessary to inject drugs to shrink the blood vessels of the scalp to stop the bleeding.
"Here we come, there are pieces of yarn!" The store manager found the first-aid kit and brought it over. After opening it, there was finally a piece of yarn.
Xie Wanying asked the elder sister to take a piece of gauze to cover the wound, and after her eyes determined the extent of the wound, her fingers pressed on the scalp around the wound to stop the bleeding, so as to block the blood flow.
A group of people around watched with bated breath, and finally it seemed that the blood hadn't kept coming out.
"Gauze pieces and bandages." Xie Wanying gave instructions.
The person next to her hastily handed her tools. Continue to press the part where her fingers are pressed tightly with a piece of yarn, and then use a bandage to press and fix it.
