What Is Fetal Death?

Most fetuses will be born at 40 weeks of gestation, but only 5% of the babies who can be accurately born in the expected delivery period are normal. However, if there are no signs of labor after two weeks of delay, measures such as oxytocin should be taken to give birth to the fetus as soon as possible, otherwise the fetus will be dangerous. The development of the fetus in the womb is an extremely complicated and magical evolution. Its life begins with a small fertilized egg that develops into a healthy baby in the womb week by week.

Fetal development

Sensory development

Sensory development

First, the sensory development of the baby

First appearance of sensory organs in the first 1 to 2 months

After 4 weeks of gestation, the retina of the fetal baby is initially formed. After 6 weeks, hearing began to form. Then small hands, feet and facial organs began to take shape. However, at this time, the baby's sensory function has not yet formed.

Formation of touch and taste in the 3rd to 4th month

After 8 weeks of pregnancy, the baby's skin begins to feel. As the number of neurons increases, touching the abdomen with your hands, the TA will squirm. The taste development is completed in 11 ~ 12 weeks of pregnancy, and various sweet and sour tastes can be felt.

Hearing begins to develop in 5 to 6 months

The baby's hearing is getting more and more developed, and frowns when you hear disliked sounds. From 18 to 20 weeks, the pregnant mommy will feel the fetal movement, and the baby will also contract the response of the pregnant mommy's touch.

Visual sensitivity in the first 7-8 months

During the 27th to 28th week of gestation, the baby's brain develops very fast, can recognize the rhythm and melody, and sometimes responds to the sound with fetal movement. At the same time, you can feel the brightness of the light and become more and more sensitive to external stimuli.

Sensory development in the 9th to 10th months

At 37 weeks gestation, the baby can respond to almost any light, and the eyes can blink flexibly. As the intrauterine space shrinks, fetal movement starts so frequently, but at this time TA's sensory development is almost the same as that of a newborn baby.

Sensory development is inseparable from brain development

In the third month, in the proportion of the body of the fetus, the head appears to be very large, and the brain has developed very complicated. In the fourth month, the brain develops rapidly, but the surface of the brain is still smooth and there is no groove return; the fifth Months, the sensory organs began to develop rapidly according to the area, and taste, smell, touch, vision, and hearing will develop in specialized areas in the brain; at this time, the number of neurons decreased, and the connectivity between neurons began to increase; the seventh At month, the fetal baby's brain cells are rapidly proliferating and differentiating, and the nervous system is developing. By 9 months, the fetal baby's brain function is more developed.

Second, promote the fetal baby's sensory development, you can do prenatal education:

1.Tactile prenatal education

With your fingertips, pat with your fingers, and use your whole hand to stroke the pregnant mother's belly, your baby feels differently in the womb! At 12 weeks of pregnancy, you can use strokes or pats to promote the development of the fetal baby's nervous, muscular system, and athletic ability. The frequency is 5 to 10 minutes each time, twice a day. When you are about 20 weeks pregnant, you can tap your fingertips or pat your belly to see if your baby responds by kicking or beating.

2.Visual prenatal education

At a fixed time each day, the flashlight is given to the belly, and the baby's head is illuminated in a flashing and extinguishing manner for 2 minutes at a time. But don't shoot the baby for a long time with a strong heat source

3. Voice prenatal education

Pregnant moms and expectant fathers can give voice prenatal education to their babies through chatting, storytelling and playing music. But pay attention to the intensity and rhythm of the sound. When listening to strong rhythmic disco music to the baby, the number of fetal movements will increase significantly, and the fetal movement amplitude will also increase. When the fetal heart rate is increased, it will also be accompanied by breathing like sobbing. , The number of fetal movements is significantly reduced, the heart rate is slowed, and even in a quiet sleep state.

4, the impact of pregnant mommy taste on the baby

The taste of food eaten by pregnant mummy may become the first experience of food taste through amniotic fluid, so many baby's preferences for food after birth are consistent with the taste preferences of pregnant mummy. Therefore, if a pregnant mommy wants her baby not to be picky in the future, she must fully take in nutrition during pregnancy and cultivate her baby's eating habits from the fetal period.

Fetus has a colorful entertainment life

Fetus has a colorful entertainment life

From the moment she knew she was giving birth to a small life in her belly, expectant mothers poured all their love on the baby. Although the expectant mother cannot see the baby, she still pays close attention to everything: is he healthy? what is he doing? In fact, in the long 280 days, the baby is used to sleep most of the time. But when he is awake, he is an energetic, naughty little guy with a colorful and entertaining life you can never imagine: walking around, yawning, playing with umbilical cords, sucking his fingers, or even scratching himself Little feet ...

Migrating amniotic fluid

Before they could be called "fetuses", they began to swim around their mother's womb. This aimless swim had no posture at all, as they wanted, and they were as easy as a little hippocampus. This "fitness" activity lasted from 6 weeks to the end of pregnancy, until his size was too large to float in the amniotic fluid.

Yawn, suck and swallow

When the expectant mother is 11 weeks pregnant, her appearance begins to change quietly, but because the baby is only one plum, it is not enough to attract attention. Relatively speaking, the baby in the abdomen has undergone great changes. His heart began to supply blood to all internal organs and exchanged blood with embryos through the umbilical cord. This is an important milestone for the baby's physical growth. At the same time, he also learned some new skills-yawning, sucking and swallowing.

The baby yawns just like us, with his mouth wide open, but it is not known if he yawns because he is sleepy and tired; the baby's nutrition is transmitted through the umbilical cord, and his sucking and swallowing appear It doesn't make much sense, holding the floating amniotic fluid as a toy in and out of his mouth, swallowing and playing, maybe as fun as we blow bubbles!

Move your bones and make faces

When the baby's hair and nails grow rapidly and the genitals begin to show gender characteristics, what he will do is even more amazing: he can move his arms freely, bend his fingers and toes, and in two weeks, the baby can still bend, Stretching and turning the palms, wrists, legs, and toes makes the movement more flexible; when his bones become harder in late pregnancy, he will often turn over, kick around, shake hands, open hands, The mother will feel that the baby is sliding on both sides of the waist, as if hugging her mother and coquettish with her. These are all fetal babies moving muscles and doing sports.

The fetal baby continues to suck and swallow. In addition to amniotic fluid, a new invention has been added-finger sucking. This is really the original root for the baby's love of sucking fingers after birth. Of course, he still touched his face from time to time. Sometimes, he even pulled his little feet over and put them in his mouth.

At this time, his facial expressions have also been enriched. Learning to smile and frown, we can think of it as a sign of whether the baby is satisfied with the surrounding environment, or it can be used as an exercise for his facial nerve muscles. No matter what our baby is At this time he learned to make a face, but at this time he was just 10 weeks old, and he was only 6 cm long!

Except for sleeping, the baby was not quiet for a while. The expectant mother's womb did not provide him with any toys. But there is one "toy" that has to be mentioned, which is the umbilical cord. It was originally a "channel" for delivering nutrition to the baby. It was really boring. The baby with extreme babies regarded it as a toy, turned around the umbilical cord, and held the umbilical cord to play. After playing tired, he took a break, and when he was full of energy, he became more and more active, but he didn't know the danger, he lurked aside, and some babies were entangled by the umbilical cord during the play and became dangerous.

Ear Lingling

The baby is very "smart". When he was 24 weeks old, he could distinguish different sounds from outside the womb and inside the mother's body. So talk to your baby as much as possible, and try to pat your belly. If you can put some beautiful music, it's even better. You should know that the baby's pulse will speed up after hearing, and it can move with the rhythm of the music! In fact, the baby's ears are already very sensitive at 6 months. The baby is "snooped" by the ultrasound. He can feel the slight pressure of the ultrasound probe on the mother's belly, although the skin and amniotic fluid on the belly play a certain role. Barrier effect, but when the sound of ultrasonic vibration reaches the baby's ear, it can approach 100 decibels, which is equivalent to the sound of a train entering a station. Therefore, this kind of noise baby must not like.

Preemptive territory

The longer the baby grows, the more he develops in his mother's stomach. The baby had his own method. He squeezed the organs in his mother's body, moved his intestines to his upper abdomen, and his stomach became smaller. Because of this, many expectant mothers developed stomach discomfort.

Snore

Would a baby burp? It may seem like a joke, but it is true. Expectant mothers will find the fetal baby's rhythmic fetal movement during the late pregnancy, which will appear several times a day. The doctor explained from a medical point of view that this is the sound that the baby makes when swallowing amniotic fluid, and it is also his "practice" breathing action, so that the lungs can mature faster, so the snoring of the baby is not really a snoring.

Open eyes practice

We always think that the baby can open his eyes to see this colorful world only a few days after birth. In fact, this is not the case. In the second trimester, the baby's eyes can rotate in the eye sockets, and he will also actively open and close the eyes. Eye, can't imagine! Not only eye-opening exercises, the five sensations of the babysmelling, seeing, hearing, smelling, and touchingall started to work, fully preparing for the upcoming birth.

Excretion

Did you know that when the baby is ready to be born, he will swallow the fetal hair and other secretions that have fallen off the body a little bit and store them in the intestine, which will stimulate the fetus' intestinal peristalsis, excrete the feces, and excrete urine. liquid.

300 bones

From the textbook of physiology, we know that there are 206 human bones, but the baby will have more bones than the adult, at least 300. After birth, some bones will fuse together as they grow.

The fetal baby will leave the mother after having more than 70 different reflex capabilities. After this not a long 40 weeks, the fetal baby has developed from a small embryo into a healthy baby. It will laugh, roll, and open. Seeing, swallowing and sucking, this period has undergone complex and unimaginable changes. For the baby, the days in the mother's belly are happy, without worry, and without thinking; for the mother, this is also the best time in life, because the baby gives the mother beautiful memories that can't be forgotten for life. .

After experiencing these wonderful moments, the baby has been ready step by step, ready to curl up and enter the strange world through the 23cm birth canal, ready to start his brand new life.

3 critical nutritional periods for fetal growth

Within 40 weeks of the fetus's life in the mother's womb, it also has its own growth rules. The cradle net reminds expectant mothers to grasp the three key nutritional periods of fetal growth during pregnancy!

Critical period 1: 4-12 weeks gestation

The first 3 months of the fetus in the mother's belly is a critical period for the development of the neural tube and main internal organs. At this time, if the mother's folate intake is insufficient, it may cause abnormal development of the fetal nervous system. Therefore, you should add a small dose of folic acid from the first trimester to the first trimester of pregnancy. In addition, you should eat more foods rich in folic acid, such as vegetables such as cabbage, lettuce, rape, and animal liver. Kidney, beans, fruits, dairy products, etc.

Critical period 2: 16-24 weeks gestation

The fetus is a critical period for rapid bone and brain development within 16-24 weeks of pregnancy. At this time, expectant mothers should eat more calcium-rich foods to promote fetal bone development, such as soy products, dairy products, seafood, leafy green vegetables. In addition, supplement DHA-rich nutrients. DHA is an essential fatty acid for brain development. It is an essential polyunsaturated fatty acid for human brain nutrition. It is an important substance that constitutes neurons in the cerebral cortex and is the material basis for the formation of the retina. Can promote brain development and improve memory. However, DHA cannot be synthesized by the human body, and can only be obtained through external supplementation. After ingestion, nuts such as walnut kernels rich in natural linoleic acid and linolenic acid can be processed by the liver to synthesize DHA; in fish and seaweed DHA can also be extracted.

Critical period 3: 32-37 weeks gestation

At this time, the fetus needs to store more nutrients, and its metabolic activities are also enhanced, requiring a lot of calories and protein. At this point, expectant mothers can add more legume protein and eat more tofu and soy milk. In order to meet the needs of a large amount of calcium, you can eat more seafood such as laver.

Experts suggest that pregnant women should adjust their diet according to their weight gain and store the necessary energy for childbirth.

When does the fetus begin to develop

When does the fetus begin to develop

Baby from scratch. The baby actually settled in the mother's body may happen only in the second and third weeks of the month. The baby develops from a fertilized egg cell. The initial development followed the most primitive way of proliferation in the biological world, one became two and two became four. About 4 days or so, divide into cell clusters. After that, the mass of fertilized eggs reaches the uterus along the fallopian tube.

Signal of pregnancy

At the end of this month, expectant mothers will suddenly feel that their appetite has changed quietly. For example, what they usually like to eat is suddenly no longer interesting. They have not had a regular menstrual period. They have not felt before, such as tingling. Or a sense of swelling. To make expectant mothers tired is another signal to expectant mothers. Another phenomenon cannot be ignored. During abnormal physiological periods, a slight red or brown stain may be secreted from the lower body, and slight spasms in the abdomen may follow. You need to know that this is not a temporary disorder in your menstrual period, it may be the result of the implantation of the baby in the endometrium.

Tips:

Real time to conceive in October

It takes about 266 days from the time an egg meets the sperm to the delivery of the fetus. However, the entire pregnancy process is generally calculated at 40 weeks or 280 days, which is calculated from the first day of the last menstrual period. We generally use the first day of the last menstrual period as the first day of pregnancy and count as 1 month (28 days) every 4 weeks. In this way, the entire pregnancy is 280 days and 40 weeks.

What do fetuses in the uterus need for a 6-week fetus

What do the fetuses in the palace need?

The tiny fetus is buried in the folds inside the mother's womb. At this time, the head, body and limbs of the fetus have been formed. He lives in a "little bubble" filled with liquid, and in a week, he will double from 4mm to 8mm.

Reminder to expectant mother

Vitamin B should be added in time from the beginning of pregnancy, especially before the 12th week of pregnancy.

This can reduce the chance of fetal spina bifida, jaw cleft, and rabbit lips.

The fetus is wrapped in an amniotic sac and swims gently.

8 week fetus

He now began to show his face, and his nostrils and lips grew. The tongue and mouth are also growing. Hands and feet became more nuancedfingers and toes began to grow. Although the eyes are still just two small spots under the thin skin. However, the little guy has completely got rid of the "fertilized egg" title and entered the "fetal" stage. His length also reached 16 mm.

Reminder to expectant mother

Feeling tired at this time, so it is necessary to increase the amount of sleep each night. Drinking a glass of milk before going to bed can help you fall asleep.

The fetus's eyes appeared.

12-week fetus

Organs inside the body are growing. And he can already yawn, stretch his legs, and even roll. It's just that the mother can't feel these changes yet, because his size is like a plum, which can reach 8 cm in length this week.

Reminder to expectant mother

This is a high-risk period for fetal abortion. Regular inspections should be strictly performed to protect the fetus.

Fetus as big as a plum.

16-week fetus

His body began to be covered with fetal hair-when the fat on the fetus was not rich, the fetal hair could keep him warm. The bones strengthened. At this time he had hearing in the womb for the first time. He is 14 centimeters long.

Reminder to expectant mother

Mother's sleep has many benefits for the baby's growth in the belly. Falling asleep in an airy place and following a regular routine of sleep are very beneficial to the health of mothers and infants.

The fetus can hear the sound.

Special recommendation: 16-week infant growth

23 weeks fetus

He has a regular schedule for falling asleep and waking up. Often the opposite of the mother's schedule. When the mother was preparing to sleep, but the fetus woke up, he would kick the mother and say hello to the mother. He has grown to 28 cm.

Reminder to expectant mother

The swollen abdomen at this time has affected the sleep of pregnant women. It is best to sleep on the left side to make blood flow smoothly and help the kidneys' metabolic function.

The fetus has its own schedule.

Fetus at 37 weeks

After about three weeks, he was fully mature. Even if he is born now, no special care is needed. His fingers were fully mature and his toenails had grown. His eyes were already mature. He is about 45 cm long.

Reminder to expectant mother

When falling asleep at this time, you can use a small pillow between your legs to facilitate side sleep.

The first and second weeks of January during the first trimester of pregnancy: Since ovulation usually occurs on the 14th day of the menstrual cycle, if the menstruation does not come on time after two weeks, you may be pregnant.

During this period, the uterine floor of the pregnant woman's uterus rises between the chest and the umbilicus. The height of the uterine floor is 26-32 cm, and the fetal movement is strong. The growing uterus makes the abdominal wall taut, and the strong fibers in the abdomen show light red or dark purple stretch marks. This phenomenon can also occur in some breasts and thighs.

Some pregnant women have increased melanin secretion, and pregnancy spots can appear on the face. At the same time, the skin color around the nipple, lower abdomen, and vulva also gradually turns black, which is normal. During this period, the number of lower extremity edema increases, and some pregnant women have pregnancy hypertension syndrome, anemia, dazzle, varicose veins, hemorrhoids, constipation, cramps, etc. If these symptoms occur, pregnant women should seek medical treatment in time and insist to go to the hospital for inspection every two weeks .

During this period, the abdomen height of the pregnant woman was raised. The uterine floor rose from the two horizontal fingers below the chest to a point below the heart fossa. The height of the uterine floor was 29.8 to 34.5 cm. Squeezing gastrointestinal symptoms aggravated and moved the diaphragm muscle upwards. The heart shifts to the upper left. The heart and both lungs are squeezed, and the blood volume increases to the highest peak, so the heart load increases, the heartbeat breaths faster, asthma, bloating, loss of appetite, and constipation. At this time, the fetal head begins to gradually fall into the pelvic cavity, squeezing the bladder. , Cause frequent urination.

At this time, the pregnant woman is bulky, has inflexible movements, and is easily tired. Pay attention to rest, eat a small number of times, and stop sex to avoid premature birth and infection. Insist on checking every two weeks during pregnancy, once a week from 36 weeks, and should check in time if there are abnormalities.

During this period, the height of the uterine base of the mother is about 30 to 35.3 cm. As the fetus enters the pelvis, the position of the uterine apex moves down, which reduces the compression of the heart, lungs, and stomach, relieves bloating, and increases appetite. With the increase of bladder compression, symptoms such as frequent urination, constipation, waist and leg pain, and more vaginal secretions are conducive to lubricating the birth canal. Because the fetus is large, the amniotic fluid is relatively small, the abdominal wall is tight and hard, and there are irregular contractions.

Pregnant women should insist on a weekly prenatal check-up in order to detect abnormalities as soon as possible. During this period, pregnant women should pay attention to clean their bodies and massage their nipples. Sexual life is forbidden. Sexual life can cause water breakage and premature birth.

40 weeks is when your baby is born. Usually the baby will be born this week, but it will be two weeks earlier or later, which is normal. If your baby shows no signs of being born two weeks after the due date, consult a doctor at the hospital because the fetus is too mature and sometimes dangerous.

At 40 weeks, the clear and transparent amniotic fluid became turbid, and the placenta function began to deteriorate. The placenta had completed its mission after the fetus was born.

Waiting for the baby to be born is uneasy, anxious, and urgency. At this stage, try to talk about more relaxed topics such as how to play with your baby in the future.

Pregnant women will feel very nervous and irritable during these weeks. This is normal. At the same time, pregnant women will feel heavier and heavier in the past few weeks, so pay attention to exercise carefully, avoid standing for a long time, and avoid slipping when taking a bath. In short, take a good rest, pay close attention to changes in your body, and be ready for labor at any time.

The third to sixth month of pregnancy is the first stage of rapid brain cell proliferation, known as the "rapid brain growth period." It is mainly the increase in brain cell volume and nerve fibers that increase the weight of the brain. The second stage is 7-9 months of pregnancy, during which the proliferation of support cells and nervous system cells, and the increase in dendritic branches, allow the already established brain nerve cells to develop into synaptic junctions between nerve cells and cells. To conduct the excitement of brain nerve cells. For human intelligence, the increase in dendrites of brain nerve cells is far more important than the increase in the number of cells.

What I want to remind you here is that the development of each embryo in the uterus is not the same. Here is just a brief introduction to the development process of the fetus. If you find your situation and what we have introduced to you, Do nt panic if you come in small; or you can go to the hospital to consult a doctor and check accordingly.

If there is an abnormality in the fetal heart sound monitor, delayed deceleration, and repeated occurrences during the labor process, the umbilical cord may be suspected of being around the neck. After confirmation, a direct laparotomy is required. Most expectant mothers have a fear of umbilical cord entanglement, worrying about the danger of their baby, and think they must face a cesarean section. However, the umbilical cord is not only delivered by caesarean section, but also needs to be evaluated with related symptoms.

In addition, the degree of umbilical cord around the neck is mostly loose, only a few will be tight. When the umbilical cord is wrapped around the baby, and the winding is tight, and the baby feels uncomfortable, he will move around to find a comfortable position, move left and right, when the baby turns back, the umbilical cord winding will be lifted naturally The baby will rest comfortably for a while. Of course, if the number of umbilical cords around the neck is large, the chance of the baby moving out will be less.

The umbilical cord around the neck does not necessarily lengthen the labor process, and the fetal death is not necessarily caused by the umbilical cord around the neck. Medicine is developed, and the chance of fetal death due to the umbilical cord around the neck is getting lower and lower. Expectant mothers should trust the doctor's specialty and not have to panic too much.
