Chapter 389 [389] The Bleeding Site Is Different

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 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, pushing her away and rushing up to apply pressure. She called to the junior sister: "You go to senior sister, I'll do it 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. When she slowly removed her hand and towel, she saw that the wound was bloody and bleeding, and she couldn't help but cover it with a towel.

People around me covered their faces and eyes, but they didn't dare to look at it: it was too scary!

Only the surgeon would definitely dare to look at it at this time.

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 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 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, it's probably just scalp damage.

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 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 blood vessels under the skin cannot contract on their own, resulting in profuse bleeding. If compression cannot stop the bleeding, in addition to suturing, injection of drugs is required to shrink the blood vessels in the scalp to stop the bleeding.

"Here, there's 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 instructions.

The person next to her hurriedly handed her the tools. Use the gauze piece to continue to press the area where her fingers are pressing, and then use a bandage for compression and fixation.
