What does unstable lie of fetus mean?
In the late stages of pregnancy, from 37 weeks onwards, unstable lie is the term given to a baby that continues to change its position inside the womb. The baby’s position is not classed as unstable until this point as, prior to this, the baby will move around the womb as a normal part of its development.
What is the normal fetal lie?
Normally, the position of a fetus is facing rearward (toward the woman’s back) with the face and body angled to one side and the neck flexed, and presentation is head first. An abnormal position is facing forward, and abnormal presentations include face, brow, breech, and shoulder.
What does lie mean in pregnancy?
Definitions. Lie – the relationship between the long axis of the fetus and the mother. Longitudinal, transverse or oblique.
What are the different fetal lie?
There are three main types of fetal lie: Longitudinal lie (vertex and breech are both longitudinal lies) Transverse lie (the baby’s long axis is perpendicular relative to the mother’s; in other words, the baby is sideways) Oblique lie (the baby is essentially at an angle between longitudinal and transverse)
How is Malpresentation diagnosed?
On abdominal examination, the head is felt in the upper abdomen and the breech in the pelvic brim. Auscultation locates the fetal heart higher than expected with a vertex presentation. On vaginal examination during labour, the buttocks and/or feet are felt; thick, dark meconium is normal.
What happens with low lying placenta?
Low-lying placenta As your pregnancy progresses, your womb expands and this affects the placenta’s position. The area where the placenta is attached usually stretches upwards, away from your cervix. If the placenta stays low in your womb, near to or covering your cervix, it may block the baby’s way out.
Which placenta position is best for normal delivery?
This is because having the placenta on the back wall of the uterus means feeling the baby s movements and kicks early and stronger. Moreover, posterior placenta is considered to be the best for the baby as it allows the baby to grow and descend to the right position and align in the birth canal for a vaginal birth.
What is the best fetal position for birth?
The best position for the baby to be in to pass through the pelvis is with the head down and the body facing towards the mother’s back. This position is called occiput anterior (OA). In breech position, the baby’s bottom is facing down instead of the head.
What if baby is sideways at 36 weeks?
After 36 weeks, if your baby is transverse, your doctor may offer to carry out a external cephalic version (ECV). This is when she places firm but gentle pressure on your tummy to encourage your baby to turn. If the ECV is successful, you can wait for labour to start.
How do I turn my transverse baby?
If your baby stays transverse, your doctor may do an external cephalic version (ECV), this is where they attempt to turn the baby from the outside using pressure on the baby’s head and buttocks. This procedure can be painful for the mother, but pain relief may be used and complications are rare.
What is an unstable lie during pregnancy?
What Is An Unstable Lie? You may have recently been told that you have an unstable lie or are concerned that you may have one, but you don’t know what that means. In plain terms, an unstable fetal lie is when your unborn baby moves positions within the womb during the later stages of pregnancy (after 36 weeks).
What is unstable lie and how common is it?
Unstable lie is more common in preterm babies as they are smaller and therefore have more space to move and so this is a normal finding prior to 36 weeks, so don’t worry if your baby is in different positions during scans prior to this point in pregnancy. Other causes of unstable lie which make it more likely for it to exist are:
What is an unstable lie oblique?
unstable lie oblique orientation of the fetus that is neither transverse nor longitudinal, but that converts to one or the other before or during labor. Oblique orientation of the fetus that is neither transverse nor longitudinal; it converts to one or the other before or during labor.
What is the best way to do unstable lie?
The main thing I suggest for unstable lie is the same as for the persistent breech. Seven (7) Forward-leaning Inversions (FLI) in one 24 hour period, about 15 minutes to 2 hours apart. Do not set an alarm to wake yourself, sleep is paramount! Do not do FLI after eating or during heartburn.
