What is the presentation of the fetus during pregnancy?
First of all, it should be noted that finally this parameter can be established after 32 weeks of gestation. Until then, the fetus is still very mobile, can change its position several times a day.
In obstetrics it is customary to distinguish the following types of presentation:
- Pelvic floor. It is observed when the baby's ass is facing directly to the entrance to the small pelvis. The following types are distinguished:
- Gluteal - the baby is located in the uterus head up, legs are stretched along the trunk, the feet are near the head;
- foot - one or one foot of the fruit is facing the entrance to the small pelvis;
- mixed - the entrance is adjacent to the legs and buttocks.
- occipital - the nape is facing forward and first appears from the birth canal during delivery;
- before the circle, the head is turned sideways;
- frontal - the so-called, wired point during labor is the forehead;
- facial - the fetus passes forward along the ancestral ways, the back of the head is maximally deflected backward.
It is worth noting that the pelvic presentation of the fetus during pregnancy is often called incorrect. It is noted in only 3-5% of parturient women.
What is meant by the term "position of the fetus"?
The location of the conditional line, passing from the crown of the fetus to the coccyx in relation to the axis of the uterus, in obstetrics is usually called the position of the fetus. In this case, classify it as follows:
- longitudinal position of the fetus, - it is noted, when the baby is located along the uterus during pregnancy;
- oblique - the head and legs rest against the lateral walls of the uterus;
- transverse - the body of the fetus is located across the uterus.
Thus, the head and pelvic presentation of the fetus in the longitudinal position completely coincide with the axis of the uterus. The oblique position - the conditional lines intersect at an acute angle.
