The fetal station in labor and delivery
Being closer to the birth, it is important to know whether the fetus is in the right position for the birth process or not. Generally, entering the third trimester, the baby will move more actively in the womb to the position of labor, towards the pelvis. Knowing the position of the fetus in the right place for labor or not is important for mothers.
If the baby’s position is right, the labor process will be easier. The right position of the baby for normal labor is called the occiput anterior. The baby is facing down and his body is facing the mother’s back. The head of the fetus will generally start moving towards the pelvis at 28 to 32 weeks’ pregnancy. But some new fetuses entering the pelvis not long before labor begins.
It should be noted that the fetal head entering the pelvis is not all experienced by pregnant women because in some cases it is found that the fetal head may not enter the pelvic door completely, this is called CPD (Cephalo-Pelvic Disproportion) or disproportion between the head and pelvis. Some of the factors that influence it including a narrow maternal pelvic factor, a large baby head factor or a large baby’s size, and a short placental factor or location covering the birth canal. If you have CPD, some obstetricians recommend not doing normal labor because it can harm both the fetus and mother.
Characteristics of the Fetus Entering the Pelvis
Some signs can show the fetus entering the pelvis, such as discomfort in the upper abdomen is reduced, more easily breathe, more often feel false contractions and the occurrence of changes in body shape.
The following are the characteristics of the fetus entering the other pelvis that can be identified, including:
- More frequent urination
The characteristics of babies entering the pelvis that can be felt are pregnant women will more often urinate. Even, frequent urinary problems also occur since the beginning of pregnancy. When the fetus enters the pelvis, pregnant women will urinate more often because the volume of urine can be less or more. Pressure in the bladder becomes greater when the fetus enters the pelvis.
Other characteristics of the fetus entering the pelvis, pregnant women can also experience indigestion. This condition can cause pregnant women to experience frequent stomach twists during pregnancy, flatulence, excessive gas in the stomach, and sometimes some mothers will also have diarrhea. The mother’s abdomen will also look very light because the fetus enters the pelvis. If these symptoms have arisen, the mother must be careful so that she can look after the baby until the time of delivery.
- Pain in the vaginal, rectal, and perineal area
The position of the fetus into the pelvis can make pregnant women feel uncomfortable, especially in the area of rectum, perineum, and vagina. This condition occurs when the baby moves a lot or give kicks in various directions. These can continuously cause greater pressure. Some pregnant women can feel the fetus too downward. This condition is very reasonable because the mother is ready to enter the labor process.
- The waist feels heavy
When the fetus enters the pelvis, the mother’s waist is like getting a heavy burden. To deal with lumbago, pregnant women should not hold on to the same position, if you often sit then you have to keep up with standing too, and vice versa.
How to make a fetus enter the pelvis in the right position
Generally, the position of the fetus has entered the pelvis at the 32nd week of pregnancy. Some pregnant women also wait until the age of 36 weeks the position of the head of the fetus. Mothers can do several things to accelerate the fetus moving into the pelvis, such as mopping, squatting exercises, walking, even often making prostrations. Besides, several recommendations can be made to accelerate the decrease in the fetal head such as by walking, light exercise such as doing yoga and avoid sitting too long. In addition to these movements, there is also a method called ECV or the External Cephalic Version, which puts pressure on the abdominal area so that the fetus can be in the proper position. If this ECV method fails, most doctors will recommend a cesarean section.
Decreasing the position of the head during labor must show progress, midwives or obstetricians should be able to analyze the decrease in the fetal head either in the Hodge, station or sublime plane, and everything. These are all will be monitored with partograph.
What is Hodge Field?
The Hodge field is an imaginary line in the mother’s pelvis during labor that is created to determine the position of the fetal head’s decline. Taken from the name of the inventor, Hodge. It is very important for a Midwife or obstetricians to know the location of this Hodge field, but first, we will discuss what are the benefits of knowing the Hodge field.
Here we have submitted some benefits of knowing the Hodge field.
- Knowing the location of the lower head of the fetus
- Knowing the precise location and presentation of the fetal head
- Determine the progress of labor
Also, after knowing the Hodge field, here we explain the Hodge field:
- Field of Hodge I: a field formed on the circle of the upper door of the pelvis with the upper part of the symphysis and promontorium.
- Field of Hodge II: this field is parallel to the Hodge I plane located at the bottom of the symphysis.
- Field of Hodge III: this field is parallel to the fields of Hodge I and II, located as high as the right and left ischiadic spines.
- Field of Hodge IV: this field is parallel to the fields of Hodge I, II, and III, located as high as the coccyx os.
Determining the station in the fetal other than using the “Hodge field”, can also be known by “station and conference”.
The station in labor is the height of the lower part of the fetus on the birth canal described in conjunction with the spina ischiad. This is located in the middle position between the Upper Pelvic and Down Pelvis. On VT inspection the degree of descensus is determined based on “zero station”. Zero points are in the position as high as the middle pelvis and the degree of descensus is estimated to be at a few centimeters above or below zero point. If the lowest part of the fetus is at zero, it is called engaging.
