No matter what, it is absolutely correct to wait for the teacher's instructions when you are not sure.
Now that the teacher has not given any instructions, I can only try to keep calm.
The classmate Geng Yongzhe opposite was very patient and didn't ask, just waited.
Compared with other boys he has been with in the class, Geng Yongzhe is really able to stand still when he is not moving. This kind of muteness is probably not even comparable to that of Meng Hulu's monitor.
Xie Wanying vaguely felt that Geng was a very perseverant person.
In front of him, the surgeon's hand first touched the lower segment of the uterus to determine the position of the fetal head. The experienced Director Yu mumbled based on the feeling: "It's not good."
When the others heard the words of the surgeon, they tensed up. Assistant Dr. Peng put his hand on the fundus of the uterus and prepared to assist the surgeon.
"Don't be nervous." Director Yu said to his assistant on the ground.
The director is definitely a big shot. Director Yu looks more stable than Teacher Li, and so far he speaks in a slow and slow tone.
Director Yu's scalpel cut open the uterine wall, only about three centimeters, and then used surgical scissors to cut open the amniotic membrane. He changed the suction device and sucked in the amniotic fluid inside to prevent the umbilical cord from being flushed out by the amniotic fluid and causing fetal asphyxia. When the suction is almost done, use it again.
Use your own hands to tear the incision to 10 centimeters, and cut across the uterine wall in the same direction as the uterine muscle fibers. This tearing is easier and less damaging than incision.
Everyone can see the dark hair of the fetus.
"Hey." Dr. Peng couldn't help being 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, a cesarean section operation involves opening the belly of a pregnant woman, exposing the entire fetus to the doctor's field of vision, and the doctor can easily lift the fetus out.
Reality has never been such a simple and perfect thing, especially in medicine. What you need to know is that cutting open the belly of a pregnant woman does not mean removing the whole belly, but opening a hole. It is like a bag of things. After you open the hole, you can only look at it first.
In order to maintain the integrity of the items in the bag, care must be taken to prevent damage to the entire item when pulling the items out of the bag. It is best if the mouth of the bag is large enough and the objects inside are small enough.
It is easiest to pull it out. The most advantageous conditions for cesarean section are impossible to exist. How can a doctor cut the uterine wall of a pregnant woman to the maximum extent? He must help the patient narrow the uterine incision as soon as possible, which will affect the uterus.
The damage is minimized and the pregnant woman has the chance to get pregnant next time. The pregnant uterus is mainly expanded 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 to have in reality, the doctor has to think of another best condition to pull out the fetus. What is it? Think about the moment the bag is opened, and the things inside are just in time to put the hand in.
It is the easiest position to pull out, and it is easiest to pull out a lot of things at this time. Since the general position of the fetus during childbirth is to enter the pelvis with the head down, the conventional transverse incision is set three to four centimeters above the pubic bone, and many women's uteruses happen to be at this position.
When opened in this position, the fetus's ears or the back of the occiput will be exposed. At this time, it is easier for the doctor's hands to hold the fetus' head and take the fetus out of the mother's body.
These are general situations. What should you do if you encounter special cases? Some doctors judge that it is difficult to remove the fetus and will directly make a longitudinal incision or enlarge the incision and change it to a T-shaped incision.
