What Is A Posterior Birth?

A posterior or postpartum delivery is a delivery in which the fetus growing in the womb has not turned to the rage, i.e. the head down and the face towards the mother’s back, but its legs are towards the mother’s uterus.
Usually, the fetus is head down in the womb, head toward the mother’s hips, but the fetus in the stern is as if sitting in the womb.

At what stage is the final position of the fetus determined?

The fetus growing in the womb typically varies in position until the 36th week of pregnancy, after which it ends up in its final position. There is usually no obvious cause for a posterior condition, but the fetus simply adapts to the condition in the uterus.

There are different stern spaces:

• Perfect stern. The legs of the fetus are extended.
• Stern leg supply. The thighs of the fetus are against the abdomen and one or both legs are bent.

• Foot supply. One or both knees and the pelvis of the fetus are extended so that the feet are a tender part below the back.
• Kneeling. The fetal pelvis is outstretched and the knees are bent and tender.

Fetal supply is examined at the maternity clinic, from where detected or suspected cases of sternal disease are referred to the maternity clinic during the 35th or 36th week of pregnancy.

External translation of the fetus

If the fetus is in the anus, an attempt is often made to make an external turn, which means turning the fetus to the desired position, i.e., head down. This occurs at the 36th week of pregnancy, after which spontaneous reversal of the fetus is rare, in addition to which the conditions for external reversal deteriorate as the pregnancy progresses further. In some cases, however, an outdoor translation can be done even when the child is full-time.

At the maternity outpatient clinic, the supply of the fetus is confirmed by an ultrasound examination, after which the doctor assesses whether an external translation can be attempted. In all cases, external translation cannot be done. The situation can be aggravated by the first childbirth, a scanty amount of amniotic fluid, anterior wall obstruction, maternal obesity, a contraction-sensitive uterus, and attachment of the tender part of the fetus to the mother’s pelvis.

In the procedure, the doctor tries to turn the fetus from the top of the mother’s abdomen into the correct position. If necessary, the mother will be given an anti-contractile medicine during the procedure. About 40% of first-time mothers and about 60% of previous mothers succeed in external translation.

How to perform a posterior birth?

The birth of a child in the stern is possible, either downstream or in a section, depending on the case. If, for one reason or another, an external translation cannot be performed, the doctor will assess the possibility of a birth. If the prenatal conditions are not met, a planned section is performed approximately one week before the calculated time. Similarly, caesarean section is often found if childbirth does not start spontaneously and the pregnancy is premature.

The choice of method of delivery is influenced by the following factors, among others:

• The volume of the pelvis of the mother. The mother’s pelvis and birth canal must not be too narrow.
• Fetal weight. The large size of the baby can be a barrier to lower birth.
• Fetal supply. The position of the baby affects whether a birth can be performed. A perfect stern makes childbirth easier.
• Amount of amniotic fluid. Too much or too little amniotic fluid can prevent birth defects.
  
• Fetal health. The baby must not suffer from, for example, cardiovascular problems.
• Umbilical cord position. The umbilical cord must not be wrapped around the fetus in a problematic way.

The postpartum delivery is treated by experienced doctors and midwives, but otherwise the delivery proceeds normally, following the well-being of the mother and fetus, and is allowed to proceed as spontaneously as possible until the effort phase. The mother pushes the child out until his scapulae are visible, after which the doctor helps the child’s shoulders and head out.
