What should I know in the ninth month of pregnancy (33 ~ 36 weeks)?

The growth and development of the baby at this time, the fetal weight is 2 ~ 2.5 kg, the body length is 45 ~ 48 cm, and the biparietal diameter is about 8 cm. Strong fetal movement, fetal position can still be changed. At 36 weeks, the amniotic fluid is about 1000 ~ 1500 ml. During this period, the cerebral cortex has developed well, and the fetus has the ability to breathe and suck, such as premature birth, and it is easier to survive. From the appearance, the subcutaneous fat increases, the whole body becomes round, the skin wrinkles decrease and become smooth, the skin color is reddish, the hair decreases, the hair is thick, and the nails grow out, which has completed the appearance development. Fetal brain is well developed, hearing is sensitive, consciousness is further developed, and expressions such as emotions may appear. The internal organs are fully developed and the sexual organs are fully developed. Male testicles shrink and female labia majora swell. Between 32 and 34 weeks of pregnancy, if the fetus's head is up, it will turn down at this time, but about 4% of the fetus will not turn down until birth. My horizons began to broaden for a while, and I began to learn to focus on a certain place. My lungs can breathe on their own.

The mother's physical change is the most headache for pregnant women since pregnancy, especially at the end of the ninth month, when the uterine bottom has reached the highest point and the uterus is full of the whole abdominal cavity, it will rotate wonderfully, and this rotation direction is right; At this time, the height of the fundus is 29 ~ 34 cm, which is the highest period of pregnancy. The position rises directly below the heart, 2 fingers below the xiphoid process. The enlarged uterus compresses the stomach and heart more seriously, and pregnant women will have discomfort symptoms such as palpitation, chest tightness, asthma, dyspnea, abdominal distension and inability to eat. The uterus has greater pressure on the bladder and frequent urination is more serious. Abdominal skin stretch marks are aggravated, and some pregnant women occasionally have slight contractions. During this period, there are more and more leucorrhea to adapt to childbirth and protect vagina. By the 33rd week of pregnancy, the weight gain rate of pregnant women is faster than at any time after pregnancy, and this situation will last for about 36 weeks until the blood volume increases by 40%. As the fetus begins to move down, the shape of the pregnant woman's stomach will change.

Prevention of Common Diseases and Coping with Common Reactions Some pregnant women often feel itchy skin on the abdominal wall in the third trimester of pregnancy. This is because there are stretch marks on the abdominal wall, and excessive stretching stimulates the sensory nerve endings of the abdominal wall. If it is not accompanied by other symptoms and signs of intrahepatic cholestasis of pregnancy, it is not a disease, and the symptoms are often mild and do not need special treatment and treatment.

Prevention of common diseases and response to common reactions: Harm of intrahepatic cholestasis to fetus. With the progress of pregnancy, intrahepatic cholestasis of pregnancy will have a great impact on the fetus, causing great harm, which can increase the mortality rate of the fetus, lead to premature delivery of pregnant women and intrauterine distress of the fetus. The fetus often dies in the uterus, especially after uterine contraction, and can also cause postpartum hemorrhage of pregnant women, which should be paid attention to. It is suggested that pregnant women with itching symptoms should check their liver function and jaundice index in time, so as to find abnormalities in time and deal with them as soon as possible.

Mild patients should closely monitor the fetal memory, fetal movement 3 times a day. Fetal movement is an important index to reflect intrauterine memory. If the fetal movement decreases or disappears, you should go to the hospital for further examination immediately. So far, intrahepatic cholestasis of pregnancy can only be cured after delivery. Because intrahepatic cholestasis of pregnancy will endanger the life of the fetus, it is necessary to terminate the pregnancy in advance if necessary, so that the fetus can get rid of the bad intrauterine environment. Pregnant women diagnosed with moderate or severe intrahepatic cholestasis of pregnancy should be hospitalized for observation until safe delivery.

Prevention of Common Diseases and Response to Common Reactions Harm of Umbilical Cord Prolapse There is one umbilical vein and two umbilical arteries in the umbilical cord, and there is umbilical cord matrix to protect umbilical arteries outside the blood vessel. The fetus is connected with the mother through umbilical cord and placenta, and constantly obtains nutrients and exchanges metabolic wastes through umbilical artery blood vessels. During this period, the umbilical cord is easy to knot, wrap around the neck, compress or prolapse, especially when the fetal head is high or breech, premature rupture of fetal membranes may cause the umbilical cord to protrude from the uterine cavity to the outside of the cervical mouth, that is, umbilical cord prolapse, and the fetus will lose the way of material exchange, which will endanger the life of the fetus and even cause sudden death of the fetus.

Prevention of common diseases and coping with common reactions Premature delivery caused by placental abnormality and placental abruption can cause premature delivery, vaginal bleeding, headache, dizziness, sudden increase of blood pressure and other symptoms, but there is no abdominal pain. Premature labor caused by placental abruption may have similar symptoms as above, but it also has abdominal pain. In case of any of the above situations, you should be admitted to the hospital immediately for further examination and treatment. If vaginal bleeding is not much, abdominal pain is not obvious, and the situation is good, under close observation, sometimes delivery from the vagina can be smooth; If vaginal bleeding increases, or abdominal pain worsens, cesarean section should be performed immediately, and delivery should be terminated quickly, so as to avoid bleeding endangering the life of mother and baby.

Prevention of common diseases and response to common reactions What are the causes of placenta previa? The normal position of placenta should be in the anterior and posterior walls and the left and right walls of the upper part of uterine cavity. If the placenta accreta is too low, it is placenta previa in the lower part of the uterine body or directly covering the cervix, which is one of the main causes of bleeding in the third trimester of pregnancy. If not handled in time, it will endanger the lives of the mother and fetus. At present, the etiology of placenta previa is not very clear, and the possible reasons are endometrial damage, such as repeated curettage, late pregnancy, uterine surgery, intrauterine scar and so on. Studies have shown that 85% ~ 90% of patients with placenta previa are not pregnant for the first time.

Prevention of Common Diseases and Coping with Common Reactions Manifestations and Countermeasures of Carpal Tunnel Syndrome At the end of pregnancy, some pregnant women will feel arm pain, numbness, tingling and burning sensation in their palms and fingers. Pain can radiate upward to the upper arm or shoulder, and the symptoms will be aggravated at night, which will affect sleep; In severe cases, the sick hands are weak and the motor function is weakened. During pregnancy, there is water and sodium retention in pregnant women, which can cause local tissue edema, narrow the space in carpal tunnel and cause compression of median nerve. Pregnant women with chronic wrist strain, tendon sheath cyst or obvious edema in the third trimester of pregnancy are prone to this disease. Pregnant women can brake the wrist of the affected side and fix it in a neutral position; The doctor injected hydrocortisone acetate locally. Or take vitamin B6.

After delivery, with the discharge of excess water in the body, tissue edema disappears, and this symptom is often alleviated. However, it will take some time to fully recover, about two weeks to six months. If the symptoms are serious, such as hand weakness and dysfunction, you should go to the hospital for surgery in time to cut off the transverse carpal ligament and decompress. Generally, when pregnant again, this symptom may still recur.

The manifestations and coping methods of non-labor uterine contraction are called Hick's contraction abroad. Hick's contraction starts from the top of the uterus and continues to the bottom. Generally painless, only a few pregnant women feel unwell, usually lasting about 30 seconds, and occasionally lasting about 2 minutes. During uterine contraction, in order to relieve the discomfort caused by Hick contraction, pregnant women can try to lie down and relax, or stand up and walk. Changing posture will completely stop uterine contraction. Although Hick's contractions are not real pains, it is not easy for pregnant women to distinguish between Hick's contractions and uterine contractions that lead to premature delivery. This kind of contraction should be described to the doctor at the time of diagnosis.

Hick's contractions usually occur in the second half of pregnancy. In the ninth month of pregnancy, with the end of pregnancy, Hick's contractions intensified and sometimes even pain appeared. Although the force of Hick's contraction can't give birth to a fetus, this kind of uterine contraction is helpful to cause cervical shortening and cervical dilatation, which is helpful to the delivery before labor and prepares for the rapid contraction of the uterus after the delivery of the fetus. However, pregnant women with high risk of premature delivery, or uterine contractions of 4 times or more per hour, or uterine contractions with increased vaginal discharge and lower abdominal pain, are advised to see a doctor in time.

To correctly handle the premonition of labor, we should pay special attention to whether there is vaginal bleeding, that is, bloody mucus from the vagina, which is called seeing red or bleeding first. This is the result of cervical changes, separation of the fetal membrane from the uterine wall near the internal opening of the cervix and capillary bleeding. This is a harbinger of labor, which usually occurs within 24 to 48 hours and should be admitted to hospital as soon as possible. Preventing premature delivery is the main task this month. If there is sudden bleeding, amniotic fluid outflow or multiple contractions, you should be admitted to the hospital immediately. At this stage of pregnancy, the viability of the fetus after delivery is very good and there is no need to protect the fetus. In addition, on the way to send pregnant women to the hospital, we must avoid bumping and try to keep it steady.

Avoid daily life and adjust your mental state. During this period, pregnant women's physical and psychological burdens are aggravated, and their physical discomfort and activities are limited. The fear of childbirth often makes pregnant women feel uneasy and nervous, and their mood swings are very obvious. Pregnant women should have a scientific understanding of pregnancy and delivery, eliminate fear and irritability, adjust their emotions, learn delivery knowledge, practice delivery-assisted movements and skills, and make themselves face delivery rationally and confidently. Family members should give special tolerance and understanding to pregnant women's mood during this period to help them get through this stage smoothly.

Methods and Strategies to Improve Insomnia Pregnant women should relax and adjust themselves. When they can't sleep, they should also keep a good attitude to calm themselves down and keep calm, and sleep will come naturally. Don't be upset, because the more anxious you are, the more you can't sleep. The prospective father should be considerate, supportive and helpful to the pregnant wife, because pregnant women in the late pregnancy are prone to depression in addition to physical changes, fear of imminent delivery and worry about the health of their children. Husband fell asleep at night, which is also a stimulus to pregnant women, which will make her feel lost and affect her sleep. Therefore, husbands should spend more time with their pregnant wives, say a few words of comfort, give them a considerate hug and gently massage their legs and waist, which will ease the mood of pregnant women, improve their sleep and make them fall asleep easily.

Action safety tips pregnant women are heavier, inconvenient to move, prone to fatigue, and often feel palpitations after activities. They should reduce the amount of exercise, pay attention to rest and prevent a lot of physical exertion. Pregnant women have unstable center of gravity, so they should walk slowly and steadily. Don't fall or trip. It's best to find something to lean on or support when standing, and keep your legs apart for a certain distance. Go up and down the stairs as little as possible, and do not require standing for a long time. Avoid asking for a bath or doing something for a long time. Pay attention to reasonable rest and avoid overwork. If you need to go out, avoid too long; When pregnant women go out, they should avoid strong direct sunlight and wear a sun hat or umbrella to prevent the spots from getting worse.

Choose the appropriate means of transportation to 2 months before labor, those who go out for a short distance should walk and try not to take the bus; If you need a long-distance bus ride, pregnant women should try to avoid the rush hour when going to work, and you can take a bus when it is not crowded. Don't go to work by bike or drive to work by yourself. During this period, pregnant women are relatively heavy, so it is not convenient to get on and off by bike, and it is not easy to deal with emergencies flexibly; Cycling in crowded places is prone to traffic accidents, which brings danger to pregnant women and fetuses; Cycling is easy to aggravate the symptoms of backache that pregnant women often have. And driving depends on the road surface, road signs, but also control the speed, beware of other vehicles and pedestrians, nervous, not good for pregnant women and fetuses. It's best not to drive by yourself. In short, women in the third trimester had better not ride bicycles or drive cars to avoid accidents.

Choose shoes because the uterus is enlarged, the abdomen is raised, and the pregnant woman's body center of gravity moves forward. Only when the shoulders lean back, the abdomen leans forward and the waist shrinks back can we maintain the balance of the body. The choice of shoes is particularly important, and its safety should be considered first. It is best for pregnant women to wear flat-heeled shoes, with strong and wide heels to support their bodies, and the shoes are closely combined with their feet; It is best to have anti-slip lines on the soles; Shoes can conform to the shape of the arch part of the sole; Soft and comfortable materials, such as cotton shoes, soft-soled leather shoes, etc. High heels, sandals that fall off easily, hard plastic shoes and slippers that are easy to wear and slip are not suitable for women in the third trimester, which is the main cause of low back pain. Shoes with too low heels are also not good, which will make it difficult for pregnant women to walk, and the vibration will be directly transmitted to their feet, even to the spine and the back of their heads, making pregnant women feel uncomfortable; With the increase of pregnancy, the pressure on the foot center increases. This kind of shoes can lead to flat feet, which is also the cause of foot fatigue, muscle pain and cramps. In the third trimester of pregnancy, pregnant women are prone to foot edema due to poor blood flow in lower limbs due to heavy load. Pay attention to wearing slightly larger wide-toed shoes.

Sexual life in the ninth month of pregnancy, pay attention to controlling sexual life at this time. Pregnant women are huge, physically and mentally uncomfortable, and their sexual desire drops. Husbands should restrain themselves. Because the uterus is sensitive at this time, some pregnant women can have slight contractions at ordinary times, such as giving strong mechanical stimulation to the uterus, which can easily cause uterine contraction and lead to premature delivery in severe cases. Therefore, it is not appropriate to have sex at this time, and it is best to start abstinence, which is good for the safety of the mother and the fetus.

Careful medication can lead to fetal dysplasia and other effects, so pregnant women must be careful with medication. The effects of many drugs on the fetus have not been fully affirmed so far. It is generally believed that the chances of adverse effects on the fetus will increase if the dose is large and the time is long. Therefore, we should carefully measure and choose reasonably. E drugs.

How to spend hot summer or cold winter in the third trimester? How to deal with the hot summer? In some areas of our country, the temperature in midsummer can be as high as 30 degrees. Above c, normal people will feel muggy and humid. Pregnant women in the third trimester are more likely to feel uncomfortable because of their obvious weight gain, increased oxygen consumption and decreased organ adaptability. Therefore, we should pay more attention to avoid behaviors that may cause physical discomfort.

1. Pay special attention to heatstroke prevention. The metabolism of pregnant women is very strong, and they are more prone to sweating than normal people, which can easily lead to skin diseases such as sweat rash. At the same time, due to excessive sweating and excessive loss of water and salt in the body, the regulation function of the central nervous system is prone to obstacles, which will reduce the brain's ability to regulate body temperature. Therefore, women in the third trimester are more prone to heatstroke, especially those who are not heat-tolerant. When the outdoor temperature is too high, the air humidity is high and there is no wind, pregnant women should take care of themselves and try not to go out. When the indoor temperature is too high, air conditioner or electric fan can be used to blow, and ice cubes can also be used to cool down. When you have to go out, you should wear an umbrella or a sun hat and bring enough drinking water. Don't ask if it's been sunburned for too long.

2. avoid hot and cold. It is necessary to prevent the temperature in the room with air conditioning and electric fan from being too low, and do not let the electric fan blow directly on pregnant women to prevent pregnant women from catching a cold due to cold, wind or cold and heat.

3. Ensure hygiene and rest. Pregnant women should pay more attention to hygiene in summer to ensure adequate sleep and rest. Take a bath frequently, change your underwear frequently and keep your body clean. Wear loose clothes, preferably cotton or linen products that absorb sweat, which can not only keep the body cool and comfortable, but also inhibit the growth of fungi. Do not choose close-fitting clothes with poor permeability and hygroscopicity and containing chemical fiber ingredients, especially pregnant women with itchy skin and edema of lower limbs. In addition to ensuring a high-quality sleep of not less than 8 hours every night, it is best to rest at noon every day 1 ~ 2 hours.

4. Pay attention to food hygiene. In addition to adequate nutrition and reasonable collocation, we should drink more water, eat more light food and eat more fresh fruits and vegetables, so as to increase vitamins and increase the body's disease resistance. You can eat less and eat more meals, but be careful not to overeat and eat overnight, stale, stale and spoiled food to prevent intestinal infectious diseases.

How to deal with the cold and dryness in winter is also a big test for pregnant women and fetuses.

1. Clothes and life. It is windy in winter, the temperature is low, the temperature fluctuates greatly and the air is dry. It is easy to reduce the respiratory resistance of pregnant women, and it is easy to suffer from diseases such as colds, and viral colds can cause fetal malformation or endanger fetal health. Whether to use drugs in the third trimester will make pregnant women in a dilemma and increase their worries. Therefore, it is best for pregnant women to take a positive attitude, strive to protect themselves, strictly prevent colds, pay attention to warm clothes, pay attention to shelter from the wind and cold when going out, prevent colds, and increase or decrease clothes at any time according to temperature changes. At the same time, we should try our best to keep the indoor temperature stable, so as to avoid the body being difficult to adapt in the third trimester, the resistance dropping, and diseases occurring. Pregnant women had better not stay in supermarkets, theaters, stations and other places with many bacteria for a long time. When someone at home or at work suffers from diseases such as colds, try to avoid face-to-face contact; Wear a mask when necessary and wash your hands frequently to avoid respiratory infections through hands and mouth.

2. Open the window for ventilation. Because of the cold weather, it is easy to close the doors and windows to keep warm, but if you don't open the window for ventilation for a long time, it will cause indoor air pollution, insufficient oxygen and increased bacterial concentration. Pregnant women in the third trimester will feel unwell because of their heavy physical burden and increased oxygen consumption. They are prone to hold their breath and catch a cold, which is not conducive to the health of pregnant women and will also adversely affect the growth and development of the fetus. Be sure to pay attention to the window ventilation in the bedroom. You can choose to be in windless weather, or let pregnant women ask in another room to avoid strong winds blowing directly on pregnant women.

Get some sunshine. Pregnant women should often bask in the sun to promote the absorption and utilization of important trace elements such as calcium and phosphorus. When the weather is fine, you can go for a walk outside, get in touch with the sun, breathe fresh air, exercise your bones and muscles, promote blood circulation and strengthen your physique. When the weather is bad, you can bask in the sun in a sheltered and sunny place indoors. Only direct illumination can promote the production of vitamin D and the absorption of calcium and phosphorus by sunlight. It is useless to bask in the sun through the glass, but enough light can help pregnant women keep active and happy. Pregnant women are advised to bask in the sun for at least half an hour every day in winter.

4. Strengthen nutrition. It is freezing in winter, and the body needs extra energy to resist the cold, so it is necessary to increase nutrition; The growth rate of the fetus in the third trimester is accelerating, and the demand for nutrition is also increasing. We must pay attention to strengthen nutrition, ensure that all kinds of nutrients needed by the body are sufficient, and enhance the resistance of pregnant women. This is an important measure for the body to resist the invasion of germs and cold. Because pregnant women need more calories in winter, they should eat more and eat better than other seasons, appropriately increase some high-energy meat and dairy products, and at the same time pay attention to a certain amount of fresh vegetables and fruits every day to supplement vitamins and maintain the balance of pH in the body. Pregnant women should also pay attention to the problem of eating out-of-season vegetables and fruits, which may contain some plant nutrient solutions and other additives to promote growth. For pregnant women, it is best to eat fresh fruits and vegetables grown in the natural environment.

5. Travel safety. The snowy and windy season is very dangerous for women in the third trimester. Pregnant women are huge, inconvenient to move, easy to fall or sprain, and even lead to premature delivery. It's best to avoid going out. If you have to go out, you should walk very carefully. In the freezing season, especially in snowy weather, pregnant women should be accompanied when going out to prevent accidents. In addition, for pregnant women, especially women in the third trimester, driving in wet and snowy weather is prone to traffic accidents. Considering the decline of emergency ability caused by pregnancy, fragility and premature delivery, women in the third trimester must not drive by themselves for the safety of themselves and their unborn babies.

Pregnant women should adhere to prenatal examination according to the doctor's arrangement, and pay attention to whether there are pregnancy complications and abnormal delivery factors. If you have symptoms such as leg swelling, headache and nausea, you should see a doctor in time and receive examination and treatment as soon as possible.

It is suggested that pregnant women with itching symptoms should pay attention to the conscious symptoms of itchy skin. During the prenatal examination, inform the doctor and cooperate with the doctor to do the necessary examination, and timely detect the liver function and jaundice index. If you are sick, you should strive for early treatment to avoid accidents.

The nutrition plan is a scientific and reasonable diet in the last stage of pregnancy, which should ensure the quality and reasonable collocation. Due to fetal enlargement. When the gastrointestinal tract is oppressed, pregnant women often feel discomfort in the upper abdomen, often lose appetite and can't eat too much at a time. They can take a balanced diet of eating less and eating more to ensure adequate nutrition. When you have an appetite, you must eat more foods that can enhance your physical strength and make good physical reserves for childbirth. It is necessary to appropriately limit the intake of fat, sweets and fruits, reduce the amount of staple foods such as rice and noodles, and prevent the fetus from growing too big. If you are near delivery and have edema of lower limbs, you should also reduce the intake of salt and pay attention to prevent constipation.

Therefore, the uterus is very sensitive to stimulation. Forced defecation may stimulate the uterus, cause contractions, and even lead to premature delivery in severe cases. Therefore, pregnant women should eat more foods containing dietary fiber and vitamins, such as vegetables, fruits, seaweed, etc., and try to avoid constipation. But after eating a lot of fruit, we should pay attention to drinking less water.

Fetal nutritional needs If pregnant women are well nourished and generally in good condition, the development of the fetus will be good. In addition to the nutrition that pregnant women need, they also need to supplement what the fetus needs. At this time, the nutrition of pregnant women is extremely important for the health of themselves and the fetus.

The continued development of the fetus needs nutrition; Tissue that supports fetal growth, including placenta, fetal membrane, umbilical cord, etc. , medically known as fetal appendages, also need nutritional maintenance; The enlargement of the mother's uterus, the productivity required during childbirth, postpartum breastfeeding, etc. All need nutrition; At this time, it is also the time when the fetus grows bones, muscles and fat layers, and the nutritional needs are great.

At this time, you can refer to the fun of raising a baby.

Fetus and mother are flesh and blood, and they have subtle psychological induction. Everything the mother says and does will have a subtle influence on the fetus. Studies have found that a wide range of tastes plays an extremely important role in improving brain function. People with rich interests in life often use the left and right hemispheres alternately, which can promote the balance between the left and right brains, improve the function of the brain and have strong creativity. The interest of pregnant women in life undoubtedly plays a key role in the balanced development of the left and right hemispheres of the fetal brain. If pregnant women are physically and mentally healthy and have a rich spiritual life, such as listening to music, reading books, reading poems, traveling or enjoying works of art, it is very beneficial to the physical and mental development of the fetus. Good taste is conducive to regulating emotions, improving health and cultivating sentiment, which is very important for the next generation. Pregnant women's interest in raising a fetus must be elegant and regular in order to achieve a good effect of raising a fetus.

The number of fetal movements varies with pregnancy. After 9 months of pregnancy, fetal movement decreased. During the day, the number of fetal movements is also different. Generally less in the morning, and gradually increase later. Mostly at night. In the meantime, fetal movement should continue to be monitored. If there is abnormal fetal movement and intrauterine hypoxia, it is recommended to go to the hospital in time. For pregnant women with intrahepatic cholestasis of pregnancy, the number of fetal movements should be increased. At the same time, the fetal heart rate should also be monitored. If the fetal heart rate is too fast or too slow, greater than 160 beats per minute or less than 120 beats, irregular or weakened, suggesting that there may be a critical situation, you should also see a doctor immediately. Pregnant women with pregnancy-induced hypertension syndrome should regularly monitor blood pressure and edema, and attach great importance to any abnormality. This period is prone to premature birth, so we should pay close attention to it. If vaginal bleeding, running water and regular abdominal pain are all signs of premature delivery, you need to see a doctor immediately and check and diagnose as soon as possible.
