He Xiangyu looked back and saw that while the junior sister was rescuing someone, someone was trying to pull the sleeve of the junior junior sister, warning loudly: "Doctors are saving people, don't get in the way, just stand aside!"
Several people immediately obeyed the order and retreated obediently.
Liu Jingyun couldn't hold down the young man's bleeding area 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 perform heart compressions on Yingying and ask her to come over.
!”
Turning around and running away, He Xiangyu rolled up her sleeves and came to the side of the junior sister, pushed her away and rushed forward to apply pressure, calling to the junior sister: "You go to senior sister, I'll do it here!"
"Second senior sister, you have to keep pressing on her. She has a cardiac arrest. There is a chance -" Xie Wanying said to the senior sister.
"I know, I won't stop until you tell me to stop!" He Xiangyu mustered up all her energy and planned to press 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 and came to the senior sister and asked: "What's going on?"
"The bleeding can't be stopped!" Liu Jingyun pressed hard on the patient's bleeding area until her hands began to tremble, and her voice trembled.
"Move away a little and let me see where the bleeding is." Xie Wanying said.
Liu Jingyun was not very confident. When she slowly removed her hand and towel, she found that the wound was bloody and bloody, and she couldn't help but cover it with a towel.
People around me covered their faces and eyes, not daring to look at it: It was too scary!
Only the surgeon would dare to look at it at this time.
Asking the senior sister to move her hand away, Xie Wanying carefully examined the wound in detail. She must first identify the condition of the wound. Violent injuries to the head caused by impact force can be called brain trauma, craniocerebral trauma, or craniocerebral injury.
.Craniocerebral injury is divided into scalp injury, skull injury or brain injury within the skull. Now, whether this patient has one of these injuries or a combination of the three injuries requires preliminary identification.
The patient's pupillary reflex is present and no abnormality is found. It can be initially determined that there is no intracranial brain damage. The human skull is hard and the destructive force is not very terrible, so it is impossible to cause skull damage. Therefore, it is probably just a scalp injury.
Don't underestimate scalp injuries, because the human scalp is rich in blood vessels, and the amount of bleeding will suddenly become large and cause the patient to go into shock.
The patient's blood pressure dropped, and his complexion and lips turned a little white. It was correct to stop the bleeding immediately. However, hemostasis on the scalp was different from hemostasis on the skin in other parts of the body.
The scalp is divided into five layers. Scalp injury and bleeding are caused by damage to the subcutaneous tissue layer rather than the skin layer. The rich blood vessels in the human scalp refer to the numerous blood vessels separated by fibers in the subcutaneous tissue layer. When the scalp is damaged, the subcutaneous blood vessels cannot shrink on their own.
As a result, there is a lot of bleeding. If compression cannot stop the bleeding, in addition to suturing, drugs need to be injected to shrink the blood vessels in the scalp to stop the bleeding.
"Here, there is a piece of yarn!" The store manager found the first aid box and brought it over. After opening it, there was finally a piece of yarn.
Xie Wanying asked her senior sister to cover the wound with a piece of gauze. After determining the scope of the wound with her eyes, she pressed her fingers on the scalp around the wound to stop the bleeding, thus blocking the blood supply.
A group of people around him watched with bated breath, and finally it seemed that the blood had stopped pouring out.
"Gauze pieces and bandages." Xie Wanying gave the instructions.
The person next to her hurriedly handed her the tools. He took the gauze piece and continued to press the area where her fingers were pressing, and then used a bandage for compression and fixation.
