It is harmful to have a baby before the due date.

Guide: Doctors who give birth to children always stay away from ripe melons, but many parents choose to give birth to children in advance in order to choose a day or anniversary when they are in good health. For this practice, the doctor said it was very irresponsible.

For weddings, trips and new stores, people like to choose auspicious days and take good signs. I didn't expect that some people would come out to engage in "new ideas" in such a tense matter as giving birth to children, which is staggering. Can the calculated due date be changed at will? What are the consequences of changing the delivery date? The parturient quietly chooses the day of delivery.

An obstetrician in a maternal and child health hospital in Nanjing said that more and more pregnant women are asking to have children instead. Last month, there was a pregnant woman in this hospital. Her due date was originally set in the middle of September, and her brother's birthday happened to be September 13. It will be a rare thing if two generations can celebrate their birthdays on the same day. This request was eventually rejected by the attending physician. Although it was close to the expected date of delivery, the examination showed that the pregnant woman showed no signs of giving birth and finally gave up.

Some people also asked for an extension. Some pregnant women have broken amniotic fluid, and they would rather endure it in order to survive in the "good times". Not long ago, a prospective father rushed to the hospital, and his delivery time was even accurate. At first, he was a businessman. In order to win a good lottery, he specially asked the fortune teller to choose an auspicious day and insisted that his wife give birth to a child at a certain moment before he could "get rich". As the wife had contracted, it was impossible to postpone it any longer, and the attending doctor immediately sternly refused.

Pregnancy, also known as pregnancy, is a process in which embryos and fetuses develop and grow in the mother. The average pregnancy time is about 40 weeks. In the course of nearly 10 months, very complicated, subtle and great changes have taken place. From the quiet combination of * * and the egg to the birth of a fresh life with an average weight of 3 kg, the volume of the uterus has increased from 5 ml to 5,000 ml, and the corresponding changes in other organs and systems of the mother all contain traces carefully carved by the laws of nature. Until today, we still don't know exactly how the delivery started.

How to calculate gestational age and expected date of delivery?

Accurate calculation of gestational age helps to ensure the quality of pregnancy. If menstruation is normal, the gestational age is calculated from the first day of the last menstrual cramp. Some women regard bleeding that is obviously less than the usual menstrual flow as menstrual cramps. Don't you know that this small amount of bleeding is already a threatened abortion, and the gestational age is reduced by 4 to 6 weeks. There are still a few women who have menstrual cramps for 2-3 months or longer, so they can't calculate the gestational age according to the last menstruation, so they can only calculate the gestational age with the help of obstetricians and gynecologists.

The expected date of delivery is also calculated from the first day of normal menstruation. If the number of months decreases by 3 or 9, the number of days increases by 7. If the last menstrual period is 10, June 2002, 15, the expected date of delivery is July 22, 2003. If the menstruation is irregular, the last menstruation is unclear, and the lactation period has not yet arrived, tell the doctor when the early pregnancy reaction occurs and the fetal movement begins. Doctors will also combine the results of objective examinations such as B-ultrasound to help pregnant women calculate their gestational age. The expected date of delivery is the day when you are 40 weeks pregnant.

A quiet delivery day.

If you give birth within 28 weeks to 37 weeks of pregnancy, it is called premature delivery. Term delivery within 37 weeks to 42 weeks of pregnancy is called term delivery. Delivery after 42 weeks or more of pregnancy is called overdue delivery. Although more than four weeks belongs to the full-term delivery range from 37 weeks to 42 weeks, every pregnancy has its own delivery date. Some parturients * * * secretions turn light brown or dark brown, and the amount is not much. The uterus contracts and hardens every half hour, 1 hour or several hours, which is a harbinger of labor. When the uterine contraction becomes regular, that is, it hardens every 3 to 5 minutes, and the doctor finds that the cervix is flattened, the cervix is dilated, and the exposed part drops first, the labor process comes. The cervix needs to be dilated to 10 cm to give birth. It takes about 12 hours for primipara and 6-8 hours or less for multipara. It takes several minutes to 2 hours from the complete expansion of the cervix to the delivery of the fetus. If the labor process is not smooth, the doctor will prescribe the right medicine and help appropriately.

Some women break water before labor, which is called premature rupture of membranes. If the pregnancy does not reach the weeks of full-term pregnancy, premature rupture of membranes will easily lead to premature delivery. Premature infants have low lung maturity rate and are prone to neonatal respiratory distress syndrome. Low immunity, easy infection and increased neonatal mortality. Whether it is full-term or non-full-term premature rupture of membranes, it is easy to cause intrauterine infection and puerperal infection, which has adverse effects on mother and baby. The prospective father in the news mentioned above wants to make a fortune for his business, but he doesn't know that it will probably harm his mother and son. Without the correct guidance of doctors, there may even be a tragedy of both people and money.

Cesarean section, conditional

Cesarean section is a way to terminate pregnancy. Cesarean section, as an operation, can only be performed with clear medical indications, that is, it can only be performed with sufficient medical reasons. When the fetus cannot be delivered in a short time due to intrauterine hypoxia, the pregnant woman's pelvis is too small to hold the fetus, placenta previa, and the pregnant woman's heart function is poor to tolerate delivery, it is necessary to terminate the pregnancy by cesarean section. Timely cesarean section can save the lives of mother and baby. But there are risks in any kind of operation, such as anesthesia accident, organ damage, postpartum hemorrhage, postoperative thrombosis, poor wound healing and so on. Before every cesarean section, doctors will talk to pregnant women and their families and tell them the advantages and disadvantages of the operation in detail. Cesarean section simply to choose the child's birthday does more harm than good.

In some special cases, such as pregnant women with severe pregnancy-induced hypertension syndrome, although their condition has not been satisfactorily controlled after active treatment, or eclampsia occurs, doctors will advise pregnant women to have cesarean section for premature pregnancy to save the lives of mother and baby. In a word, childbirth is a natural process and needs scientific guidance.
