   "I saw that she didn\'t even look at it, so she went in."

   Only skilled bosses dare to tie like this. The people in Guodu didn\'t think about seeing the car overturn, because they were afraid that something might happen in their hospital. These medical students are definitely thinking too much, and the teacher is standing here. If something happens, just call stop and take over.

   shows that people move fast, but at the same time, the operation is not wrong at all.

   Boss Cao Zhao didn\'t say anything, Dr. Cheng Yuchen\'s eyes became more solemn, and his nerves were tense.

   The person who does this is like a person who is driving a car and has no feeling, and those who sit in the car are shocked or surprised.

  Medical students will only see and wonder if they are moving fast, and the teacher\'s attention will go a step further. The corners of Dr. Cheng Yuchen\'s eyes were secretly gazing at the patient\'s expression.

   Whether the doctor operates quickly or not is not the most important factor, the most important thing is whether the operation is correct. Whether the operation is right or not, one of the discriminant factors is the patient\'s response.

  The key to local anesthesia is to hit the patient without pain.

   Thinking of what she said to the patient at the beginning, it was like a pain from an injection. He thought she was just fooling and comforting the patient. Unexpectedly, people really are—this? !

   The girl lying on the hospital bed didn\'t feel the pain at all, as if she didn\'t know she had been injected.

   Taking local anesthetics is a very difficult skill for surgeons. She, Xie Wanying, has also gradually gained a profound understanding after having been given the opportunity to exercise many times by the previous teachers.

  Why do some patients feel pain when taking local anesthetic, while others don\'t?

  The reason is that some doctors made the needle point wrong.

   Local anesthesia is to penetrate around the nerve plexus to allow the anesthetic to pass by itself, so local anesthesia in medical books is called infiltration. This needs to be well understood. Infiltration means that the anaesthetic needs to flood the area like a flood to cover the submerged area of ​​the nerve plexus. In this way, the doctor must make sure that the place where the anesthetic is injected can follow the flow of substances in the human body to the area of ​​​​the nerve plexus.

   After understanding this, it can be basically determined that this technical work is not easy to do.

   Occasionally, it can be seen clinically that some doctors find that the numbness is not enough after the treatment, so they have to increase the amount and adjust it again, and even let the patient endure it by himself. Because they themselves are not sure whether they can hit it properly, and they are afraid of hurting nerves and causing medical accidents. Anesthesia on the wrong nerve will have sequelae.

   It can be seen from the above analysis that the third-rate technical level is called to the nerves, and the second-rate technical level is called the poor effect of anesthesia. According to the infiltration in the textbook, the correct effect of the anesthetic can be called the standard. What is the first-class level?

   That\'s it for now. The needle goes into the skin quickly. For example, the nurse can quickly insert the needle into the vein, which can reduce the pain of the needle tip piercing the skin, because the pain cannot be escaped. If the medical staff\'s needle enters the skin and hits the target under the skin at once, it will definitely not hurt. It should be the same whether it is intravenous or local anesthesia.

   How hard is it to do this? Super hard. The textbook says that it is only infiltration, and I dare not ask that the patient will not feel completely uncomfortable after the medical staff hits the anesthetic into the patient\'s body. Local anesthesia needs to push the anesthetic, and the liquid entering the human body will definitely make the human body feel bloated.

   As long as there is discomfort, the patient\'s tone will turn into pain. Especially for children, there is no difference between bloating and pain.
