In any case, it is absolutely correct to wait for the teacher’s instructions without you being sure of.

Now the teacher has not given instructions, so he can only try hard to calm down.

Geng Yongzhe, who was opposite, was very patient and didn't ask, just waited.

Compared with the boys who have been with other classes, Geng Yongzhe is absolutely standing firm when he is still. This kind of muteness is probably not even as good as the squad leader.

Xie Wanying vaguely felt that Geng should be a very perseverant person.

In front of him, the surgeon's hand had to touch the lower part of the uterus to determine the position of the fetal head. The experienced Director Yu muttered based on his touch: "Not very good."

When others heard the words of the main surgery, they must not tense their nerves. The assistant Dr. Peng put his hand on the uterus to prepare for the main surgery.

"Don't be nervous." Director Yu Lao Shen said to his assistant on the ground.

The director is definitely a big shot. Director Yu is more stable than Teacher Li, and he speaks all in a slow and slow tone.

Director Yu's scalpel cuts the uterine wall, and only about three centimeters were cut. Then he used surgical scissors to cut the amniotic membrane, change the suction device, and suck the amniotic fluid inside to prevent the umbilical cord from being washed out by the amniotic fluid, causing the fetus to suffocate. After the sucking is almost done, use your own hands to tear the incision to 10 centimeters, and the cross-cutting of the uterine wall and the uterine muscle fibers are in the same direction. This way, tearing it opens more easily and less damage than incision.

Everyone can see the fetus's black hair.

"Oh." Dr. Peng couldn't help but feel nervous and sighed.

It can be seen that this situation is really not good. Why is it not good?

Perhaps in the imagination of outsiders, cesarean section is to open the pregnant woman's belly and expose the entire fetus to the doctor's vision, and the doctor can easily carry the fetus out.

Reality has never been such a simple and perfect thing, especially medicine. What you need to be clear is that cutting the belly of a pregnant woman is not about exposing the whole belly, but about opening a hole. For example, after you open the hole, you can only see a part of the thing inside. In order to maintain the integrity of the items in the bag, you must be careful to prevent damage to the whole item when pulling the items from the bag. It is best that the mouth of the bag is large enough and the objects inside are small enough, so it is easiest to pull it out. The best condition for cesarean section is impossible. Doctors can cut the uterine wall of a pregnant woman to the maximum extent. They must help the patient reduce the uterine incision as soon as possible to minimize the damage to the uterus, and give the pregnant woman the chance to get pregnant. The pregnant uterus is mainly supported by the fetus and amniotic fluid, so it is impossible for the fetus to be very small.

Since the above two best conditions are impossible in reality, the doctor has to think about the best other conditions to pull out the fetus. What is it? Think about the fact that when the mouth of the bag is opened, the things inside are just in the position where the hand is most easily pulled out. At this time, it is easiest to pull things. Because during childbirth, the fetus is generally positioned to enter the pelvis downward, and the conventional transverse incision is fixed three or four centimeters on the pubic bone. Many women's uteruses will be opened in this position and will expose the fetus' ears or pillow. At this time, the doctor's hands are easier to hold the fetus' head and take the fetus out of the mother's body.
