Chapter 2309 【2309】Not Easy

"Hello? Is she not afraid? Is she an intern?"

"I saw that she didn't even look like it, so she stuck in."

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

It shows that although people move fast, at the same time, they did not make any mistakes in the operation.

The boss Cao Zhao didn't make a sound, and Dr. Cheng Yuchen's eyes became more solemn, because his nerves were tense.

The person who does this is like a person who drives a racing car and feels nothing, while those who sit in the car on the sidelines are shocked or pleasantly surprised.

Medical students will only see and doubt whether the movements are fast or not, and the teacher's attention is further enhanced. Dr. Cheng Yuchen secretly glanced at the patient's expression from the corner of his eyes.

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

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

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

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

Administering local anesthetics is a highly difficult skill for a surgeon. She, Xie Wanying, also has a deep understanding after many times of training given by the previous teachers.

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

The reason is that some doctors directly miss the needle tip.

Local anesthesia is injected into 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 anesthetic needs to flood the golden mountain like a flood to cover and submerge the nerve plexus area. 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 nerve plexus area.

After understanding this point, you can basically be sure that this technical task is actually not easy to do.

Occasionally, it can be seen in the clinic that some doctors find that the numbness is not enough after the treatment, so they have to increase the dose and then adjust it, and even let the patient bear it by himself. Because they themselves are not sure whether they can hit in place, and they are afraid of nerve injury and medical accidents. If the anesthetic is wrongly injected into the nerve, there will be sequelae.

From the above analysis, it can be seen that those who have been hit to the nerves are called third-rate technical levels, and those who have received anesthetics that are not effective are called second-rate technical levels. According to the infiltration in the textbook, until the anesthetic works correctly, it can be called up to the standard. What is the top level?

This is the case now. The needle goes into the skin quickly, such as a nurse injecting a vein and quickly inserting the needle can reduce the pain of the needle tip piercing the skin, because the pain cannot be escaped. If the needle tip of the medical staff hits the target under the skin at once after entering the skin, there will definitely be no pain in the future. It should be the same whether you have intravenous injection or local anesthesia.

How hard is it to do this? super difficult. The textbook said that it was just infiltration, and did not dare to claim that the patient would not feel completely uncomfortable after the medical staff injected the anesthetic into the patient's body. For local anesthesia, you need to push the anesthetic, and the liquid entering the human body will definitely make the human body feel swollen.

As long as there is discomfort, the patient's tone will change to pain. Especially for children, there is no difference between swelling and pain.
