Abnormally, the baby enters the birth canal with his hips or
legs. Infants, which appear to be inversely during the first months and mid
months of pregnancy, often rotate until the last month and come to a flat
position. Breech presentation is observed in 3-4% of pregnant women whose birth
time is approaching.
Causes,
risk factors:
- Prematurity is the most important risk factor.
- Polar placentation (Placenta previa or placement in the
fundus)
- Oligohydramnios
- Polyhydramnios
- Myotonic dystrophy
- Congenital anomalies (Hydrocephalus, anencephaly)
- Chromosomal anomalies (trisomy 21, 28, 13)
- Twin, triplet pregnancy
- Grand multiparite (having more than 5 births)
- Having had breech births before
- Uterine anomalies
- Pelvic tumors
There are 3 types of breech arrival according to hip and foot
condition: Frank breech = the most common type, full breech, footling.
This can be understood in ultrasound performed before birth.
The pregnancies with breech arrival can be delivered normally
or vaginally according to various criteria. The following criteria may not
always be sufficient. As with every birth, the mother's examination and
ultrasound evaluation determine the decision. Today, babies with breech presentation
are mostly delivered by cesarean section. Sometimes, when there is no risk,
normal delivery is performed, especially in women who have given birth before.
Normal
(vaginal) delivery is recommended when:
- Pure breech type,
- Pregnancies over the 34th week,
- If the estimated birth weight is between 2000-3500grams,
- if the baby has no congenital disease,
- the birth action has progressed,
- if the maternal pelvis is not narrow.
In breech presentation, various maneuvers such as Pinard
maneuver, Mauriceau maneuver, Modified Praque maneuver can be applied.
Cesarean
delivery is recommended when:
- Full breech presentation,
- footling presentation,
- early birth,
- big baby,
- Serious IUGR,
- the head is hyperextended,
- pelvic stenosis
Complications
and risks of breech presentation:
Some risks and dangers that increase compared to normal
pregnancies if the baby is up-down are listed below. These dangers do not occur
in all babies who are rectally born, or that are born upside down.
- Umbilical Cord Prolapse
- Dystocia
- Increase in cesarean rate
- Laceration in the birth canal
- Uterine atony
- Humerus, clavicle, femur fracture in the fetus
- Brachial plexus injury
- Testicular damage to the fetus, brain damage, intracranial
bleeding, asphyxia
How to
understand if the baby is upside down during pregnancy?
It is not possible for the expectant mother to understand
this. Ultrasound is sufficient to understand the baby's breech presentation or
head down.
How does
the baby turn upside down?
A significant portion of the babies who are upside down in
the womb during pregnancy will recover spontaneously in the following months.
There is nothing the mother or doctor can do to help the baby recover. The baby
can turn by itself. It is inconvenient to put pressure on the womb and make dangerous
movements to correct the baby, that is, to turn upside down. Since the baby
grows larger as the months of gestation progress, the area in the uterus
narrows and the chance of the baby to return decreases. However, there may be
babies returning even in the last days of pregnancy.
What to do
if the baby is upside down?
If there is no other problem during pregnancy, there is
nothing that can be done, except to continue with the pregnancy follow-ups
regularly and to discuss with your doctor about the way of birth, depending on
whether the baby is turning or not.
When are breech
presentation babies born?
Breech presentation does not change the duration of birth. Breech
presentation is not at higher risk of being born early or late. The average
delivery time is the same as for head down babies.
Breech presentation babies are born between 37-40 weeks with
normal birth or cesarean.
