Положение плода при беременности: как определить положение самостоятельно – нормальное и неправильное – виды, косое расположение матке, полное, заднее и неустойчивое – разница

Положение плода в утробе матери в разный период его созревания

Какое положение внутри утробы занимает будущий малыш в разный период беременности. Что делать, если диагностировали неправильно предлежание?

В каком положении должен находиться ребенок в утробе на разных триместрах

Весь период созревания внутри утробы, будущий малыш меняет свое положение. Ведь он из буквально, макового зерна, становится полноценным, хоть и маленьким, человеком. Его положение меняется следующим образом:

• Первые 1,5 месяца — зародыш в виде плодного яйца передвигается к матке и там окончательно закрепляется. Чаще на задней стенке, но может и передней, верхней, нижней, боковой. На время замирает в одном положении, пока сформируется тельце.
• Примерно на 8 неделе, эмбрион уже отдаленно напоминает человечка, его размер не превышает 2 сантиметров. В этот период он начинает активно мигрировать по матке, но этого женщина не ощущает.
• На 9 неделе движения зародыша не менее активны, он находится в плодном пузыре, как космонавт в открытом космосе и передвигается по всему периметру.
• 10 неделя характерна тем, что будущий ребенок не только передвигается, но и может отталкиваться ручками и ножками от стенок матки.
• 11 неделя тоже дает возможность эмбриону активно двигаться. Он ручками и ножками делает резкие движения, плавая в околоплодных водах.
• До 24 недели положение ребенка меняется, так как он двигается. Затем активность эмбриона немного уменьшается, ведь он растет и места становится меньше.
• С 26 недели ребенок занимает позицию, которая сохранится до родов и станет определяющей при родовой деятельности. Желательно, чтобы в это время будущий малыш занял позу головой вниз и задом к маме, но не у всех получается строго следовать такому графику. Некоторые детки занимают окончательное положение только в 32 недели.
• 36 неделя — подготовка к родовой деятельности. Она может начаться в любой момент, а то и раньше и положение ребенка имеет значение для нормального течения родов.

При неправильном предлежании будущая роженица берется под контроль врачей, и возможно поступит предложение сделать кесарево сечение.

Неправильное предлежание плода, виды и причины

Неправильным считается положение будущего ребенка внутри утробы:

• Тазовое — попой или ножками к выходу.
• Косое — почти правильное, но с некоторым углом отклонения.
• Поперечное — поперек живота.

Неправильно поворачивается плод внутри утробы по таким причинам:

• Не первая по счету беременность.
• Слабый тонус матки.
• Короткая пуповина.
• Неправильное расположение детского места.
• Мало или много амниотической жидкости.
• Доброкачественные образования в полости матки.
• Обвитие пуповиной.
• Патология развития матки или особенности ее строения.
• Наличие рубца после кесарево сечения или оперативного вмешательства.

Не всегда неправильное предлежание является показанием к извлечению ребенка хирургическим путем. Иногда при тазовом или косом положении возможны естественные роды.

Диагностика расположения плода

Для правильного определения положения будущего ребеночка, проводится ультразвуковое исследование. На современном этапе делается трехмерное изображение плода, особенно при неправильном расположении, чтобы знать к чему готовиться во время родоразрешения. Даже нормальное предлежание необходимо проанализировать, чтобы исключить все возможные риски.

Может ли беременная самостоятельно определить, как расположен ребенок?

Определить в каком положении находится малыш, можно аккуратно прощупав живот. На поздних сроках уже отчетливо ощущается спинка, ручки и ножки. Кроме этого, следует обратить внимание на толчки ребеночка. Внимательно проследите за такими приметами:

• Если малыш повернут головой вверх, то толчки больше ощущаются сверху живота, а внизу активное движение.
• При поперечном нахождении ребенка живот будет непропорционально широким. Могут возникнуть болевые ощущения в области пупка.
• При правильном положении, отчетливо прощупываются ножки в верхней части живота. Давление происходит в правом подреберье в область печени. Внизу отчетливо прощупывается голова.
• Если малыш находится очень низко, то часто будут возникать позывы к мочеиспусканию и ощущаться давление в этой зоне.

После 31 недели созревания плода, он прекращает передвигаться и готовится к появлению на свет, только иногда может шевелить конечностями.
 

Если диагностировали неправильное положение ребенка

Первым делом — нельзя паниковать. Если определяется не корректное предлежание с 31 недели, до 36 еще есть время. Назначается специальная гимнастика, которая сможет помочь будущей маме правильно повернуть малыша, но даже если не получится, расстраиваться нет причин. Современные методы оперативного вмешательства мало травматичны и направлены максимально безопасно помочь появиться ребеночку на свет.
Неправильное положение ребеночка — не повод для сильного волнения. Лучше поберечь свое здоровье и малыша от негативного влияния стресса. Опытные врачи сделают все возможное, чтобы ребенок увидел свет здоровеньким. 90000 Positions Of Baby In Womb 90001 90002 What does fetal positioning mean? 90003 90004 The position of the baby in your uterus is called the presentation of the fetus. Throughout your pregnancy, your baby will move around in the uterus. It’s normal for your baby to be in a variety of positions during most of the pregnancy. Early on, the baby is small enough to move freely. You may have even felt this movement over the last few months. The larger the baby becomes, however, the more limited the movement becomes.As the end of the pregnancy approaches, the baby will start to move into position for birth. This typically involves flipping over so that the baby is head down in your womb. The baby will start to move down in your uterus, preparing to go through your birth canal during childbirth. 90005 90004 The birth canal is made up of your cervix (immediately outside of your uterus), vagina and vulva. Think of the birth canal as an expandable tunnel. During labor, your contractions work to stretch this space so that the baby can pass through it during childbirth.90005 90002 What is the most common position for childbirth? 90003 90004 Ideally for labor, the baby is positioned head-down, facing the mother’s back with the chin tucked to its chest and the back of the head ready to enter the pelvis. This position is called cephalic presentation. Most babies settle into this position within the 32nd to 36th weeks of pregnancy. 90005 90002 What other positions can the baby be in before childbirth? 90003 90004 Sometimes the baby does not get into the perfect position before birth.There are several positions that the baby can be in and each of these positions could come with complications during childbirth. These fetal positions can include: 90005 90016 90017 90018 Occiput or cephalic posterior position 90019: Sometimes the baby is positioned head down as it should be, but other times it is facing the mother’s abdomen. With the head in this position, the baby is looking at the ceiling. You may hear this position nicknamed sunny-side-up. This increases the chance of a painful and prolonged delivery.90020 90017 90018 Frank breech 90019: In a frank breech, the baby’s buttocks lead the way into the birth canal. The hips are flexed, the knees extended (in front of the abdomen). This position increases the chance of forming an umbilical cord loop that could precede the head through the cervix and cause the baby to be injured during a vaginal delivery. 90020 90017 90018 Complete breech 90019: In this position, the baby is positioned with the buttocks first and both the hips and the knees are flexed (folded under themselves).Like other breech presentations, this position increases the risk of forming an umbilical cord loop that could precede the head through the cervix and injure the baby if delivered vaginally. 90020 90017 90018 Transverse lie 90019: The baby lies crosswise in the uterus, making it likely that the shoulder will enter the pelvis first. Most babies in this position are delivered by cesarean (C-section). 90020 90017 90018 Footling breech 90019: Sometimes, one or both of the baby’s feet are pointed down toward the birth canal.This increases the chances of the umbilical cord slithering down into the mouth of the womb, cutting off blood supply to the baby. 90020 90037 90002 Is my baby at risk if it’s in a breech position? 90003 90004 A breech birth is when the baby is positioned with its feet down in the birth canal. While in the womb, the baby is not in any danger. However, in this position, the baby would be born foot first. A vaginal delivery is often a very safe form of childbirth, however, when the baby is breech, a vaginal delivery can be complicated.Because the baby’s head is larger than the bottom, there is a risk of head entrapment where the baby’s head becomes stuck in the uterus. In this situation, the baby can be difficult to deliver. Some babies in the breech position may want to come in a hurry during labor. Some providers are comfortable performing a vaginal birth as long as the baby is doing well. In many cases, your healthcare provider may recommend a cesarean birth (C-section) instead of a vaginal birth. This is a surgical procedure where an incision is made in the mother’s abdomen and the baby is removed in an operating room.There’s a lot less risk to the baby during this procedure compared to a breech vaginal birth. 90005 90002 Why does the position of the baby at birth matter? 90003 90004 During childbirth, your healthcare provider’s goal is to safely deliver your baby and ensure your well-being. If the baby is in a different position (not a cephalic presentation), this job becomes more challenging. Different fetal positions have a range of difficulties and the risks can vary depending on the position of your child.90005 90002 When should my baby move into position for birth? 90003 90004 Typically, your baby will drop down in the uterus and move into position for birth in the third trimester. This happens in the last few weeks of your pregnancy (often between weeks 32 and 36). Your healthcare provider will check the position of the baby by touching your abdomen during your regular appointments. This will happen during most of your appointments in the third trimester. In some cases, your provider may also do an ultrasound to check the baby’s position.90005 90002 Can my healthcare provider turn or reposition my baby before birth? 90003 90004 There are several ways that your healthcare provider can try and turn the baby before you go into labor. These methods do not always work and sometimes, the baby can actually turn back into the wrong position again. You can actually try some of these techniques at home and they will not harm you or your baby. They might encourage your baby to turn on its own, but there’s also a chance that nothing will happen.Even though there is not a guaranteed success rate, these methods are still recommended because they’re usually worth a try and could help you avoid a C-section delivery. 90005 90004 Methods for turning your baby can include: 90005 90016 90017 90018 External cephalic version (ECV) 90019: ECV is one non-invasive way to turn the baby and improve your chance of having a vaginal birth. This procedure is performed on the labor and delivery unit. This procedure requires two providers where one is lifting up the baby’s buttocks in an upward position and the second provider is applying pressure through the abdominal wall to the uterus where the baby is located to rotate the baby’s head forward or backward.The best time to perform this procedure is between 36 to 38 weeks of pregnancy. Afterwards, the baby’s heart rate will be monitored to make sure it’s within normal levels. You should be able to go home after ECV. 90020 90017 90018 Changing your position 90019: Sometimes you can encourage the baby to move by changing your position. Keep in mind that these exercises might not work. However, experts often feel that attempting these exercises will not hurt and if there is a chance that they might encourage the baby to turn, avoiding a C-section, it’s worth trying.These positions typically involve doing yoga-like poses. Two specific movements that your provider may recommend include: 90016 90017 Getting on your hands and knees and gently rocking back and forth. 90020 90017 Pushing your hips up in the air while laying on your back with your knees bent and feet flat on the floor (bridge pose). 90020 90037 90020 90017 90018 Using stimulating sounds to encourage movement 90019: Another thing you can try to get the baby to change position is stimulation.Music, talking, temperature changes and light could interest the baby. While in the womb, your baby can hear music, see light changes through your skin and even hear your voice as you talk. You can try placing headphone on your belly, towards the bottom, to see if this attracts your baby. Applying cool temperatures to the top of your abdomen where the baby’s head is could also promote the baby to move away and downward. Similarly to changing your position, there is no guarantee that stimulation will make your baby move, but it’s often worth a try.90020 90037 90004 A chiropractic technique, called the Webster technique, can also be used to move your hips. This is meant to allow your uterus to relax. Some providers even recommend acupuncture to help your body relax. Both of these techniques need to be done by a professional that your healthcare provider has recommended. Relaxation could promote movement in the baby and help get the baby into the best possible position for birth. 90005 90002 Can my baby change position on its own? 90003 90004 It’s always possible that your baby will reposition all on its own.In the weeks leading up to birth, the baby still has time to make adjustments and change position. Most babies find their own way into the correct position before birth. 90005 90002 How is the baby delivered when it’s breech or in another position? 90003 90004 Most birth plans begin with the idea of ​​having a vaginal birth. Your provider will look at your medical history, the scans of your baby throughout the pregnancy and the position of the baby to pick the safest form of delivery. When the baby is in a breech position or another abnormal position, your healthcare provider may suggest a cesarean section (C-section) delivery.This is a surgical procedure where an incision is made in your lower abdomen. The baby is delivered through this opening instead of through the birth canal. 90005 90004 It is possible to deliver a breech baby vaginally. However, this type of birth can be much more dangerous for the baby and the risk of injury from the umbilical cord is much higher. If the cord is compressed during birth, the baby could be deprived of oxygen and this could harm the brain and nerves. The cord could also slip around the baby’s neck or arms, causing injury.Different healthcare providers have various levels of comfort with vaginal deliveries of breech babies. Talk to your provider about the risks and benefits of different types of birth for a breech baby. 90005 90002 Does anything increase my risk of having a dangerous fetal position? 90003 90004 There are several factors that could increase the risk of a fetal position like a breech presentation. These can include: 90005 90016 90017 Going into labor too early and having a premature baby. In this case, the baby may not have had time to turn in preparation for birth yet.90020 90017 Having issues with the placenta. If the placenta is either attached too low in the uterus (a condition called placenta previa) or disconnects from the uterus before birth, it could prevent the baby from turning and getting into the right position for birth. 90020 90017 Having a multiple pregnancy. When there’s more than one baby in the uterus, it can be difficult for each baby to get into position. The limited space creates problems as the babies develop throughout the pregnancy.90020 90017 Having a uterus that is shaped differently than normal. The uterus is typically shaped like an upside down pear. When it’s shaped abnormally or has fibroids (growths that can vary in size), there might not be enough shape for a full-grown baby to move into position for birth. 90020 90037 90002 How can I prepare for complications like a breech delivery? 90003 90004 Learning that your baby is in a breech or other complicated position before birth can add to the anxiety that often surrounds childbirth.It’s alright to have concerns and questions about what this means for your birth experience. You may have developed a birth plan during your pregnancy. A birth plan is an ideal plan for your labor and delivery. These plans can be very helpful as a tool. Take your birth plan to an appointment and talk to your healthcare provider about what you are picturing for your labor and delivery. Your provider can help guide you through not only the ideal plan, but an emergency plan. Remember, things can change quickly during childbirth.Having a C-section may not be a part of your birth plan. However, the goal is to safely deliver your child and protect your health. Talk to your healthcare provider about questions and any concerns you might have about your baby’s position. 90005 90004 Last reviewed by a Cleveland Clinic medical professional on 03/04/2020. 90005 90108 References 90109 90110 90004 Get useful, helpful and relevant health + wellness information 90005 90113 90114 enews 90004 Cleveland Clinic is a non-profit academic medical center.Advertising on our site helps support our mission.

Policy 90005 .90000 Maternal Positioning – A Helpful Guide 90001 90002 90003 90004 Maternal Positioning is a phrase for talking about posture and positions women use in pregnancy and in labor for comfort or labor ease. Maternal positioning uses the 2nd Principle of Spinning Babies: Gravity. 90005 90004 90007 90008 Sitting up on the sitz bones is better for your back. 90009 90005 90004 Maternal positioning is thought to influence the fetal position during pregnancy and birth. There is some evidence both for and against this claim in the literature.90005 90004 Le Boursier du Coudray, Abre’ge ‘(тисяча сімсот сімдесят три) “counseled … that women sleep on one side so that the opening of her womb, a bit off kilter, would be pulled by gravity into alignment with the vagina.” -The King’s Midwife; A history and Mystery of Madame du Coudray by Nina Rattner Gelbart 90005 90002 90003 90002 Fetal Positioning 90003 90004 Fetal Positioning is a phrase to talk about the baby’s position in the womb. 90005 90004 Babies change position in pregnancy and during the birth process.True! That’s nature’s design! But, I do not believe fetal position changes are 90008 random 90009. I think the research lacks attention to several factors. I believe there are multiple factors that come together to affect the fetal position changes. 90005 90004 The most important reason, I believe is what I simply call “Balance.” 90005 90004 Maternal positions support the balance you have regained with daily walking, stretches and with professional body work. See samples for this in Rest Smart.90005 90004 If a woman’s womb is relatively balanced, then getting into gravity-friendly positions during pregnancy can help a breech baby to flip head down or a posterior baby to scoot over to the mother’s left side and face her right hip. 90005 90004 Contractions of labor may help a posterior rotate to an anterior position with time. Time necessary for rotation may be shortened when a woman uses gravity-friendly maternal positions. Gravity-friendly positions are more likely to reposition baby if the womb is in balance.You see how they are connected? 90005 90004 90034 90005 90002 90003 90002 Pregnancy Maternal Positions 90003 90004 Some helpful maternal positions in pregnancy are: 90005 90042 90043 Sitting with your hips higher than your knees 90044 90043 Sitting with your back straight and your rib cage lifted off your middle 90044 90043 Sitting on a firm exercise ball that allows your hips to be level with your knees or higher than your knees 90044 90043 Laying with your navel aiming towards the bed, floor or couch / sofa, if not directly on your belly, then so that eventually an imagined light -beam coming from your navel would eventually find the floor 90044 90043 Brief Forward-Leaning Inversions, once a day 90044 90043 squatting or supported squatting with your back flat against the wall and your knees bent (work gradually up to where you can squat with your feet flat on the floor for 2-5 minutes) 90044 90043 Holding your shoulders back, yet relaxed, while you walk briskly 90044 90057 90004 90059 90008 Meliss a stands and leans forward during contractions (Photo by Melissa Booth) 90009 90005 90002 90003 90002 Labor Maternal Positions 90003 90004 Some helpful maternal positions in labor are: 90005 90042 90043 All the same that are listed above, plus 90044 90043 Standing and leaning forward with your knees “soft” (slightly bent) 90044 90043 Standing and leaning back (straightening, even arching your back slightly) 90044 90043 Standing and flattening your lower back against the wall while lifting your lower abdomen during the entire contraction (See Belly Lift) 90044 90043 Kneeling 90044 90043 Kneeling and leaning forward on a bed or chair or exercise ball (hands and knees) 90044 90043 Kneeling and lifting your arms to grip a shawl or rope or bar above you 90044 90043 Kneeling and resting your elbows on the mattress or floor in front of you 90044 90043 Kneeling and resting your shoulders on the floor or mattress in front of you 90044 90043 In the deep birth tub, kneeling in a way that stretches your knees far away from your hips, so that your thighs are at a diagonal and your knees are further from your belly than your hips.This opens your pubic bone away from your spine and lets a posterior baby drop into the pelvis (engage). Do this only in active labor after you’ve tried to help baby rotate to the Left occiput transverse and that has not been able to happen for whatever reason. 90044 90043 Sitting on a birth stool 90044 90043 Lifting your arms to grip a shawl (Rebozo) and standing with your knees “soft” (slightly bent) 90044 90057 90004 Adding your instinctive movements is an excellent way to “tune in” to what your body needs to do to respond to your labor.90005 90004 90005 90004 From Christine Kent, RN 90008 “..How our spine is is primary, but how the abdominal wall is is equally primary. We’re a whole tension-compression system. The whole thing works in harmony. There are really no parts in this system; it is a whole. 90009 90005 90004 90008 The “L” shaped abdominal wall wrapping underneath the body and holding the organs up above is a major part of the female pelvic organ support system. 90009 90005 90004 90008 So yes, our work is all about what I’m calling the natural shape of the female spine.And we come to that through posture. Exercise is fabulous, but its how we hold our body, as much as we can, through the course of the day … .It becomes unconscious, pulling into this shape that we’ve trained ourselves to be in. It becomes effortless, and ultimately supportive of our abdominal and pelvic organs. ” 90009 90005 90004 Katy Bowman Says on her Facebook called Aligned and Well: 90008 “I’ve said this before, but it can not be said too many times: Posture does not equal alignment. Posture is how something looks.Alignment is how something works. “Good posture” is cultural and is typically horrible alignment. ” 90009 90005 90004 Katy has got a lot to say, and you may learn a lot from visiting her website. 90005 90004 90118 90008 The living room couch may be the biggest contributor to unnecessary cesareans. Slouching on the sacrum is not helpful. 90009 90005 90122 90123 90122 What positions to avoid resting in 90123 90004 There are times in pregnancy and labor when it is perfectly OK to lie on your back.During an exam, rolling over, doing exercises and getting body work, for example. But when you are resting, it’s better not to be on your back for the purposes of fetal positioning. You may feel comfortable on your back in the first half of pregnancy. Towards the end of pregnancy, your blood circulation will be better if you lay on your side than on your back. You can lay on your left or right as comfort directs you. Fetal positioning may be a concern of yours, however. For instance, you had a posterior labor previously or a cesarean for a long or stalling labor.Then, your resting position may matter as early as the end of the first trimester! 90005 90004 For some women, good maternal positioning includes not sitting and leaning back against the birthing tub. Lay on your side in the birthing tub, but do not semi-sit if you have any history of a long or posterior labor, shoulder dystocia or are experiencing a long second stage (pushing). Most of the time the baby will come out fine anyway, but its best to avoid this position for any longer than 15 minutes and avoid being spine-down for birthing your first baby (first vaginal birth).90005 90004 You can also lie on your right side. The directions to lie on your left side are not meant to be a prohibition against laying on your right side. You can favor your left if your care providers suggest you lay on your left. But once in a while, you need to roll over just to give your left shoulder some circulation! Somewhere, there is a woman who must lay in one particular position and will have to ignore this advice in preference to her caregiver’s advice. I acknowledge that and hope you do, too.90005 90004 90005 90122 Conclusion 90123 90042 90043 Maternal position alone is not usually enough to ensure a good fetal position by the time labor begins. 90044 90043 Balance in the uterus and pelvis precedes the success of using maternal positioning for changing fetal position. 90044 90043 Maternal positioning is Spinning Babies Principle 2: Gravity. 90044 90057 90004 Gravity-friendly positions are rarely enough. Add movement to increase flexibility and reduce pain. Before either, add balance to help both Gravity and Movement ease birth.90005 90004 90005.90000 Uterus in Pregnancy – Functions, Position, Size & more 90001 90002 Last Updated on 90003 September 20, 2018 90004 90005 90002 The uterus is a pear-shaped, dynamic female reproductive organ located in the pelvis between the urinary bladder and the rectum. The average dimensions are approximately 8 cm length, 5 cm breadth, and 4 cm thickness, with an average volume between 80 and 200 ml. Together with other vital organs of the reproductive system, the uterus plays an important role in reproduction, menses, implantation of the zygote, gestation, labour, and delivery of the baby.It is under the influence of the hormonal milieu within the body adapting to the different stages of a woman’s reproductive life. 90005 90008 What is a Uterus and How Does it Work? 90009 90002 90005 90002 The uterus is divided into 3 main parts: fundus, body, and cervix. To understand this, imagine a pear upside down. The upper globular, thick part is the fundus, the lower narrow slightly tubular part is the cervix and in between is the body. The uterus has two arm like extensions one on each side at the junction of the fundus and the body called the fallopian tubes.90005 90002 The ovary is a specialised structure that produces the ovum or the egg. Your ovary starts producing ova even before birth but the maturation and release of these ova begins after the onset of puberty or menses. Each month, either of the ovaries releases one ovum which is picked up by the fimbriae and travels through the fallopian tube to reach the uterine cavity or the inside of the womb. Then it meets the sperm (if you have had unprotected sex). 90005 90002 Where does the egg meet the sperm? The millions of sperms ejaculated into the vagina during unprotected sexual intercourse travel through the cervix, up the body, and meet the egg in the fallopian tube, where one lucky sperm gets to enter the egg to fertilise it.This results in formation of the zygote, which will then develop into a foetus. 90005 90008 How the Uterus Works? 90009 90002 It is quite interesting to see how the uterus functions. The uterus is hollow inside and has a wall that is 3 layers thick. The outermost layer is a very thin layer which forms a coat or an envelope. The middle layer is a thick layer of muscles which forms the main bulk. It gives the strength to the wall of the uterus and is capable of expanding to accommodate a growing baby and contracting to push the baby out during labour.90005 90002 The inner thin glandular lining is called the endometrium. It is the most active layer responding to all the hormonal changes and is highly specialised. It is formed every month and it prepares itself for conception and pregnancy, waiting for a fertilised egg to arrive and implant itself on it to begin the process of making a beautiful baby. For most of the months after puberty however, what it receives is an unfertilised egg. During such a situation, the inner lining is shed with some blood and that’s what is called menses and this whole cycle is called menstrual cycle 90005 90002 When a fertilised egg does arrive, it gets implanted on the endometrium.Now, it will grow to form a placenta and an embryo. The placenta forms connections with the uterine blood vessels to provide nutrition to the embryo via an umbilical cord. While this is happening the uterus sends signals to the brain to modify the hormone release such that any further egg releases (i.e. ovulation) are stopped and this temporarily ceases the menstrual cycle, thus confirming your pregnancy. 90005 90002 The uterus has a rich network of blood vessels and nerves. The nerves are responsible for the pain due to the contraction of the muscular middle layer during menstruation and during labour.90005 90008 Function of Uterus in Pregnancy 90009 90002 Pregnancy is a complex process requiring a good niche. There is interplay of various hormones and chemical mediators released by the brain and the uterus that need to be in perfect sync to conceive and maintain the pregnancy. These factors include: 90005 90002 In pregnancy the uterus provides space and a suitable environment called the amniotic sac (a water bag filled with amniotic fluid) for the foetus to grow comfortably. 90005 90034 90035 90036 Connects the mother and the baby 90037 90038 90039 90002 The uterus forms a connection between the mother and the baby via the placenta and umbilical cord to not only provide the necessary nutrition and oxygen but to also remove the waste products and purify the foetal blood until the foetal organs take over.90005 90002 Through the feedback given by the uterus, the brain regulates the hormones throughout the pregnancy to keep the uterus in a relaxed state. At full term, the uterus sends a feedback message to the brain that the baby is ready for the most awaited moment and that is when the hormones change and the uterus begins to contract at the onset of the labour. 90005 90002 Labour depends entirely on the efficient contraction and retraction of the uterine muscle fibres. Gradually the baby is pushed down with a progressive increase in the frequency and the strength of contractions.90005 90002 On completion of birth the uterus contracts and becomes a hard small ball. It is structured to reduce bleeding and revert to the non-pregnant state. 90005 90008 Changes which Happen to Your Uterus During Pregnancy 90009 90002 Nature beautifully takes care of all the adaptations that are required in the mother’s body for a healthy pregnancy. The changes are in the structure (anatomical changes) and the function (physiological changes) not only in the reproductive organs but all other systems of the body.It is the maternal adaptation to the increasing demands of the growing foetus. 90005 90052 1. Changes in position 90053 90002 The uterus undergoes immense changes during pregnancy, having a significant impact on the body as a whole, altering other organ systems too. Many of these changes are necessary to maintain pregnancy while others are merely side-effects. These changes may cause discomfort to the mother. 90005 90002 Normal anteverted position (forward bending of the uterus on itself) is exaggerated up to 8 weeks.The enlarged uterus lies on the bladder making it incapable of filling to its usual capacity and hence the increased frequency of micturition during early pregnancy is experienced. Afterwards it becomes erect, and near term it is held straight up against the spine by the good tone of the abdominal muscles. 90005 90052 2. Size of uterus during pregnancy 90053 90002 There is a gradual and steady increase in the size of the uterus from the normal 7 x 5 x 3 cm to a bigger 35 x 25 x 22 cm. The increase in size is about 5-6 times.90005 90002 90005 90064 Size during first trimester 90065 90002 During the first trimester, the uterus is around the size of a grapefruit and starts to grow out of your pelvis even though it is still inside it. This is generally around the 12 weeks stage. 90005 90064 Size during second trimester 90065 90002 In the second trimester, the uterus grows to about the size of a papaya and no longer fits inside the pelvis and is somewhere between the navel and breasts. 90005 90064 Size during third trimester 90065 90002 Around the third trimester, the uterus is the shape of a watermelon and will extend from the rib cage to the pubic area.90005 90064 Size after pregnancy 90065 90002 After pregnancy, the uterus will go back to its original shape inside the pelvis and this process is called involution and takes around 6 weeks to complete. 90005 90052 3. Measuring 90053.90000 What they are and how to tell 90001 90002 During pregnancy, the developing baby moves into several different positions. As labor approaches, some positions are safer than others. 90003 90002 The ideal position for a fetus just before labor is the anterior position. In this position, the fetus’s head points toward the ground and they are facing the woman’s back. 90003 90002 Most fetuses settle into this position by the last month of pregnancy. The anterior position is also known as a vertex, cephalic, or occiput anterior position.90003 90002 The anterior position may reduce the chances of complications during pregnancy. Learn more about this and other fetal positions in the womb in this article. 90003 90002 Possible positions of a developing baby in the womb include: 90003 90012 Anterior position 90013 90002 The best position for the fetus to be in before childbirth is the anterior position. The majority of fetuses get into this position before labor begins. 90003 90002 This position means the fetus’s head is down in the pelvis, facing the woman’s back.The fetus’s back will be facing the woman’s belly. 90003 90002 This position means the fetus’s head can be tucked in, allowing the top of it to press down on the cervix, which encourages it to open during labor. 90003 90002 A doctor or midwife may describe a fetus that lies slightly to the left as left occiput anterior or LOA, and one that lies slightly to the right as right occiput anterior or ROA. 90003 90012 Posterior position 90013 90002 The posterior position is also known as the back-to-back position.This is where the fetus’s head is pointing down, and their back is resting against the woman’s back. 90003 90002 In this position, it can be difficult for the fetus to tuck their head in, which can make passing through the smallest part of the pelvis more challenging. This can lead to a slower and longer labor than the anterior position, and may also cause a backache. 90003 90002 A fetus may be more likely to end up in this position if the mother spends a long time sitting or laying down, such as if she is on bed rest.90003 90002 The back of a fetus’s body is heavier than the front, so a pregnant woman can encourage the fetus to roll into the ideal position by leaning in the direction they want them to move. 90003 90012 Transverse lie position 90013 90002 A transverse lie position is when the fetus is lying horizontally in the uterus. Most fetuses will not remain in this position in the weeks and days leading up to labor. 90003 90002 If a fetus is still in the transverse lie position just before birth, a cesarean delivery will be necessary.90003 90002 Without a cesarean delivery, there is a risk of a medical emergency known as an umbilical cord prolapse. 90003 90002 When an umbilical cord prolapse occurs, the woman delivers the umbilical cord in the birth canal before the baby. 90003 90012 Breech position 90013 90002 The breech position is when the fetus remains with the head up instead of down in the woman’s pelvis. There are different types of breech position, including: 90003 90046 90047 90048 Frank breech 90049: In this position, the fetus’s legs lie straight upward in front of their body, so the feet are near the face.90050 90047 90048 Complete breech 90049: In this position, the fetus “sits” with their legs crossed in front of the body, so the feet are near their buttocks. 90050 90047 90048 Footling breech 90049: In this position, the fetus has either one or both feet hanging below their bottom. If a woman gave birth vaginally, one or both feet would come out first. 90050 90059 90060 90061 90002 Reasons why a fetus may remain in the breech position include: 90003 90046 90047 too much or too little amniotic fluid surrounding the fetus 90050 90047 uterine fibroids 90050 90047 an irregularly shaped uterus 90050 90047 multiple fetuses in the womb 90050 90059 90002 If a woman is carrying twins, one fetus may be in an anterior or posterior position while the other fetus is in a breech position.90003 90002 It is safe for a fetus to be in any of the above breech positions while they are in the womb. However, there are some risks if the fetus is still in a breech position when labor begins. 90003 90002 The best way of finding out which position the fetus is in is by talking to a doctor or midwife. 90003 90002 At each appointment during the second and third trimesters of pregnancy, a doctor or midwife should feel the woman’s abdomen to check the position of the fetus. 90003 90002 At the 35-36 week appointment, they will check to ensure that the fetus has moved into an anterior or posterior position.If the doctor is unsure about whether the fetus is in the correct position after a physical examination, they may request an ultrasound scan. 90003 90002 It may also be possible for the woman to tell which position the fetus is in at home. 90003 90002 When the fetus is in the back-to-back or posterior position, the pregnancy bump may feel squishy. A woman may also notice kicks around the middle of the belly, and some people may also see an indentation around their belly button. 90003 90002 When the fetus is in the anterior position, a woman may feel more kicks under the ribs.Their belly button may also “pop out.” 90003 90002 Most fetuses turn into the head-down position by 36 weeks. If a fetus is in a breech position at 36 weeks, a doctor or midwife may suggest an external cephalic version (ECV). 90003 90002 An ECV is a procedure where a doctor or midwife will try to turn the fetus manually. 90003 90002 For this procedure, they will first insert a small needle into the woman’s hand to relax the uterus. 90003 90002 Using their hands on the outside of the pregnant woman’s belly, a doctor or midwife will then gently manipulate the fetus from a breech position into a transverse lie position, then into a head-down position.90003 90002 Some fetuses turn by themselves after 36 weeks, and some even turn during labor. 90003 90002 Some people recommend moving into certain positions, taking herbal medicines, and doing particular exercises to help babies in breech turn to the more favorable birthing position. However, there is no reliable evidence to prove that any of these methods work. 90003 90002 If a person does wish to try these medicines or techniques, it is vital to consult a doctor first. 90003 90002 A baby will move into many different positions throughout pregnancy.During the last few weeks of pregnancy, most babies move into an anterior position, which is the best position for vaginal birth. 90003 90002 If a baby is still in a transverse lie or breech position just before labor, a doctor or midwife will make medical interventions to ensure the safety of the woman and baby during childbirth. 90003.
