Returning to ’90s, She Became Famous in Major Surgical Fields

   Chapter 2987 [2987] Not easy

   It was obviously rare for the group to see that she was silent on such a common question. People outside of their hearts felt something strange and looked at people outside of their hearts.

  Cao Yong pretended that nothing had happened, and said to his younger brother, "Okay, don't make fun of others."

   Huang Zhilei shouted injustice in his heart: whoever teased the younger sister, it is definitely not him but Brother Cao you.

   went to the operating room and the anesthesia was done.

   This time, the chief surgeon was replaced by Dr. Song, and the assistant was taken by classmate Pan.

   I have talked about the scalp problem before. The scalp structure is divided into four layers.

  The first layer of skin is richer in blood supply than other parts of the human body, so once blood is lost, it is easy to suffer from hemorrhagic shock.

  The second layer of subcutaneous tissue is also called the superficial fascia layer, where there are relatively large blood vessels and nerves. At that time, Xie did acupressure to stop the bleeding, and it was the vascular network in this place.

  Three layers of galeal aponeurosis, which is a special structure of the scalp, has strong toughness and elasticity, and is full of tension. It acts as a connecting muscle, connecting the temporal muscle in front and the occipital muscle behind.

   The location of the hydrocephalus drainage tube we talked about earlier is hidden below this layer, that is, the subaponeurotic layer of the fourth layer. This layer of structure is loose, so that the skin can be separated to place the shunt tube, and the superstructure has sufficient thickness to cover the shunt tube to prevent exposure.

There is a subaponeurotic space under the subaponeurotic layer. This layer can reach from the back of the supraorbital rim to the upper nuchal line. The structure is very thin and easy to be torn. Therefore, most patients with scalp avulsion injuries are torn along this layer. And we can see quite a few wounded lacerations to the ears above the eyes for this reason.

   The last layer of periosteum, needless to say, is the thin membrane covering the skull.

  It can be seen from the above structure that the scalp detached from the patient with scalp avulsion injury contains the superficial fascia layer. This layer covers the important arteriovenous vascular network and nerves that nourish the scalp. These arteriovenous vascular networks and nerves must be connected with the human body's large arteriovenous and nerve trunks, otherwise the scalp will die.

  It can be said that if the scalp of the patient with scalp avulsion is to be transplanted back, the key point of the scalp transplantation operation for the patient with scalp avulsion is to anastomos these important nerves and blood vessels.

   The medical students at the scene immediately racked their brains to recall the scalp anatomy taught in the anatomy class.

   Speaking of which, the scalp is not the top priority in the anatomy class. If it were not for seeing real clinical cases, it would be hard to recall the content of the anatomy class. This is a big reason.

Secondly, dissecting dead specimens in the anatomy class is 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 of the fresh life, which is full of the doctor's field of vision. The mass of flesh and blood was blurred, and it looked almost in a mess.

   Don't say that medical students will be confused when they look at the location of each blood vessel and nerve. If the teacher wants to find the exact point of the match, he is also painstakingly aligning it there, marking one by one, I am afraid it is a mistake. Once you get it wrong, the consequences are unimaginable.

   once again verified that surgical anatomy is the foundation of the foundation. The doctor who is playing with dissection will not sweat profusely, at least in this early stage of work. Anatomy is not good, and it will probably take more than an hour to find the exact location.

   It is normal for scalp avulsion injuries to perform overnight scalp transplantation surgery. Unexpectedly, it is only a scalp surgery, and it is not at all easier than intracranial surgery.
