What does fetal position RO stand for?

Fetal position RO stands for occipital position and right occipital position. It means that the fetal position is normal.

Fetal position is the position of the first exposure in the maternal pelvis, that is, in the four phases of the pelvis-left front, right front, left back and right back.

The representative bone of the parietal bone is occipital bone (abbreviated as O);

The representative bone of breech position is sacrum (abbreviated as S);

The first one is Mentum (abbreviated as m);

The representative bone of shoulder presentation is scapula (abbreviated as Sc).

The writing of fetal position is represented by three aspects:

1 indicates that the bone is on the left or right side of the pelvis, abbreviated as left (L) or right (R);

2. Names representing bones, such as "pillow", namely "O", "sacrum", namely "S", "chin" and "shoulder", namely "SC";

3. It means that the bone is in front of, behind or across the pelvis. For example, if the head is exposed first and the occipital bone is on the left side of the pelvis and facing forward, then the fetal position is the left occipital front (LOA), which is the most common fetal position.

The abbreviation of each fetal position is as follows:

There are six fetal positions where the parietal lobe is presented: left anterior occipital lobe (LOA), left lateral occipital lobe (LOT), left posterior occipital lobe (LOP), right anterior occipital lobe (ROA) and right lateral occipital lobe (ROP).

There are six fetal positions in breech position: left anterior sacrum (LSA), left transverse sacrum (LST), left posterior sacrum (LSP), right anterior sacrum (RSA), right transverse sacrum (RST) and right posterior sacrum (RSP).

There are six fetal positions: left anterior chin (LMA), left lateral chin (LMT), left posterior chin (LMP), right anterior chin (RMA) and right lateral chin (RMP).

There are four positions of fetal shoulder presentation: left front shoulder (LScA), left rear shoulder (LScP), right front shoulder (RScA) and right rear shoulder (RScP). Fetal position refers to the relationship between the designated part of fetal presentation (the indication point of fetal presentation) and the maternal pelvis, and the normal fetal position is mostly occipital position.

After 30 weeks of pregnancy, prenatal examination found that breech position, transverse position, pillow position and facial position were called fetal malposition, of which breech position was the most common. If the fetal position is not corrected, it will cause dystocia during delivery.

Head presentation includes pillow presentation and face presentation. Pillow presentation is divided into left front (LOA), right pillow (lot), left rear pillow (lop), right front pillow (ROA), right pillow (ROT) and right rear pillow (ROP). The posture of the fetus in the uterus before birth is very important, which is related to whether the pregnant woman will give birth.

We know that the fetus in the womb is soaked in amniotic fluid. Because the head of the fetus is heavier than the weight of the fetus, the fetus is mostly in the posture of head and hip. The normal fetal position should be that the fetal head bends over, the occipital bone is in front, and the head first protrudes into the pelvis during delivery, which is medically called "head position". This fetal position is generally relatively stable.

Although some fetuses are also head-down, but the fetal head changes from forward flexion to backward extension or occipital bone is in the rear, it belongs to fetal malposition. As for those who show their hips first (breech position), or show their feet or legs first, or even show their arms first (horizontal position). The fetal position is even more incorrect. These abnormal fetal positions are equivalent to setting obstacles in the limited delivery channel of pregnant women, which is easy to lead to dystocia. Taking breech position as an example, it is easy to lead to premature rupture of membranes, umbilical cord prolapse or dystocia, which will endanger the safety of the fetus. Another example is the supine position. Because the exposed part can't cling to the cervix during delivery, the stress on the uterus is uneven, which may easily lead to uterine contraction fatigue, resulting in fetal distress or suffocation and death.
