The group of people saw that it was unusual for her to remain silent on such a common question, and the outgoing people all felt that something was fishy and looked at the outgoing people.
Cao Yong pretended to be nonchalant and said to his junior brother, "Okay, stop teasing others."
Huang Zhilei cried out in his heart that he was wronged: Who teased the junior sister? It was definitely not him but Senior Brother Cao yourself.
Walking to the operating room, anesthesia is the best.
This time the chief surgeon was Dr. Song, and classmate Pan was the assistant.
I have talked about scalp issues before. The scalp structure is divided into four layers.
The first layer of skin has richer blood supply than the skin in other parts of the human body, so it is easy to suffer from hemorrhagic shock once blood is lost.
The second layer of subcutaneous tissue is also called the superficial fascial layer, where there are relatively large blood vessels and nerves. At that time, classmate Xie used acupressure to stop the bleeding and pressed the blood vessel network in this area.
The three-layer galea aponeurosis layer is a special structure of the scalp. It is strong, elastic and full of tension. It plays the role of connecting muscles. It connects the temporalis muscle in the front and the occipital muscle in the back.
The location of the hydrocephalus drainage tube we talked about before is hidden below this layer, that is, the subaponeurotic layer of the fourth layer. This layer of structure is loose, so it is easy to separate the skin bag and place the shunt tube. In addition, the upper structure is thick enough to cover it and prevent the shunt tube from being exposed.
There is a subaponeurotic space under the subaponeurotic layer. The range of this layer can reach from behind the supraorbital rim to the upper nuchal line. The structure is very thin and easy to tear. Therefore, most patients with scalp avulsion injuries are torn along this layer. And we can see that many injured people have tears above their eyes and ears because of this reason.
Needless to say, the final periosteum layer is the thin membrane covering the skull.
It can be seen from the above structure that the detached scalp of patients with scalp avulsion injury contains the superficial fascial layer. This layer covers the important arteriovenous and vascular networks and nerves that nourish the scalp. These arteriovenous and vascular networks and nerves must be connected to the large arteries, veins and nerve trunks of the human body, otherwise the scalp will die.
It can be said that if the scalp of patients with scalp avulsion injuries needs to be transplanted back, anastomosis of these important nerves and blood vessels is the focus of the entire scalp transplant surgery for patients with scalp avulsion injuries.
The medical students at the scene immediately racked their brains to recall in detail the scalp anatomy taught in the anatomy class.
Speaking of which, the scalp is not the top priority in an anatomy class. Without seeing real clinical surgical cases, it would be difficult to recall the content of the anatomy class. This is a big reason.
Secondly, the dissection of dead specimens in the anatomy class has a relatively clean image. Unlike today's patients, when the gauze protecting the wound is removed, the wound surface must be full of blood because it is alive and fresh, filling the doctor's field of vision. It was a mess of blood and flesh, and looked almost a complete mess.
Don't say that medical students will be confused when they look at it and try to pinpoint the locations of blood vessels and nerves. When the teacher wants to find the exact matching point, he also painstakingly aligns it there and marks it one by one. He is afraid of making a mistake. If you make a mistake, the consequences will be disastrous.
Once again, it is verified that surgical anatomy is the foundation of the foundation. A doctor who is good at dissection will not be sweating profusely at least in this early stage of alignment work. If you're not good at dissection, just finding the right position will probably take more than an hour.
It is normal to perform scalp transplant surgery overnight for scalp avulsion injuries. Unexpectedly, it is just a scalp surgery, but it is not as relaxing as intracranial surgery.
