Pelvic presentation of the fetus: norm or pathology?

Pelvic presentation of the fetus: norm or pathology?

The fetus, being in the womb of the mother, does not "sit" in place, but is in constant motion, therefore its position systematically changes, this can even be felt by the future mother. However, a certain regularity has been revealed here, according to which, up to the 28th week, it is located head up, but closer to the birth, it changes its position, already being head down, closer to the exit, so to speak.

However, in modern medicine there is the concept of "pelvic presentation of the fetus", where it is clearly established that the child "did not overturn." A similar fact can be assumed by the leading gynecologist at a regular scheduled consultation, but only the planned ultrasound after 32 weeks is able to establish it reliably. In principle, pelvic presentation of the fetus in medicine is considered the same norm as the head, but there are several nuances that must be considered before birth.

The pelvic presentation of the fetus has its own varieties, among which the following are distinguished:

• Gluteal. At the entrance to the pelvis of the mother is the ass, and the legs are unbent in the knee joints and are bent into the hip;

• Gluteal and Foot. To the entrance to the small pelvis are also directed the buttocks, but already with the legs bent at the knee and hip joints;

• Full foot. Both legs are pointed to the entrance to the small pelvis, while they are slightly bent at the knee and hip joints;

• Incomplete - foot. Here one leg is bent in the hip joint and lies slightly higher, and the other is directed into the pelvis and unbent in the hip and knee joints;

• The knee. To the entrance to the pelvis of the mother are the bent knees of the baby.

It is precisely these situations that characterize the pelvic presentation of the fetus, the causes of which can be very diverse. However, the main one is a noticeable decrease in the tone and excitability of the uterus. This phenomenon entails a decrease in its efficiency and the ability to adjust the position of the fetus. There are some risk groups, among them:

• increased fetal activity in case of polyhydramnios;

• decreased fetal activity in case of low salinity;

• Narrow pelvis;

• pathological development of the fetus ;

• Factors preventing the fetal turnaround (umbilical cord, etc.).

Births with headache are considered normal, and for pelvic - pathological, although they can occur naturally, thanks to a number of specially developed techniques and invaluable experience of the obstetrician-gynecologist. Then why are we talking about pathology? The fact is, it is these kinds of birth that are much more often accompanied by joints, for example, accompanied by fetal asphyxia and other birth trauma. In the diagnosis of "pelvic presentation of the fetus," labor often requires direct surgical intervention, in particular, a cesarean section.

Anyway, a pregnant woman should clearly realize that the fruit should turn over before the 35th week, not in vain for the 36 weeks make a control ultrasound. However, there are cases when he performed the coup on later terms, and sometimes even during direct battles. But do not hope for a miracle and expect a long-awaited coup, with folded hands. The future mommy should help the baby to properly settle in the womb, it was for this purpose that a special set of exercises was created, which, in truth, helped turn over not one kid.

So you can lie on one side for five minutes, then turn to the other and wait for the same time. Or, for example, lie on your back for 20 minutes, after putting the pillow under your waist so that the pelvis was above the lying body. There is still the simplest option, you should sleep at night on the side where the head of the child is directed.

If, after all the manipulations performed, the pelvic presentation of the fetus remains, experienced specialists perform the forced rotation of the fetus in the usual position. However, it is important to remember here that such a procedure is performed at 36 weeks only in the pathological ward of the maternity hospital under the strict supervision of ultrasound and has a number of clear contraindications that must also be taken into account.

However, the future mummy, no matter what type of presentation of the fetus is not diagnosed, should not worry, because it is the disturbances that can negatively affect the future baby, and not his current situation.
