Reasons why the fetus does not enter the pelvis Reasons why the fetus does not enter the pelvis during late pregnancy

Mothers all know that the fetus entering the pelvis is a sign of imminent delivery. However, some babies have already passed the due date but still have not entered the pelvis. Will the failure to enter the pelvis affect the delivery? This is a question that mothers are concerned about. Today, I will tell you the reasons why the fetus has not entered the pelvis.

How to treat fetal failure to enter the pelvis

Generally speaking, in the last month of pregnancy, the fetal head of a normal primipara should enter the pregnant woman's pelvis and be connected to the pelvis without floating. However, in a few pregnant women, the fetal head still does not enter the pelvis when the pregnancy is full-term, but floats above the pubic symphysis, which is called primipara head floating.

The possibility that a fat baby fails to enter the pelvis is probably caused by the mismatch between the size of the fetal head and the pelvis, and it may also cause the due date to be postponed. There is no need to worry, just let nature take its course. If you can give birth naturally, try to do so. If you cannot, do not force it. If the fetus fails to enter the pelvis successfully, you cannot give birth naturally.

The reason for this is that some pregnant women have narrow pelvises, and the fetal head is not proportional to the pelvis, so the fetal head cannot enter the pelvis. If the fetal head is too large, or the fetal position is abnormal, or placenta previa, this phenomenon can occur even if the pregnant woman's pelvis is normal. Fetal hydrocephalus or excessive amniotic fluid can also cause it. However, some primiparas do not have the above reasons, but still have the phenomenon of the fetal head not entering the pelvis.

Pregnant women with floating head in first delivery do not need to be nervous. If the pelvis and fetus are normal, they should cooperate closely with the doctor. After delivery, due to the squeezing of uterine contraction, the fetal head will also deform into the pelvis, so vaginal delivery can still be successful. If the examination finds that the floating head is caused by uncorrectable pathological factors, you can prepare for surgical delivery. If the pregnant woman with floating head has premature rupture of membranes and amniotic fluid leaks, she should stay in bed with her hips raised and go to the hospital immediately. Because this situation is very likely to cause umbilical cord prolapse, causing accidents to the fetus.

What are the reasons for not entering the basin?

First, it may be because the pregnant woman herself has a narrow pelvis, which causes the fetal head to be disproportionate to the pelvis, making it impossible for the fetus to enter the pelvis smoothly. If the fetal position is abnormal, relevant rescue measures should be taken as soon as possible.

Second, if the expectant mother's abdominal muscles are elastic, it may also cause difficulty for the baby to enter the pelvis, because tight abdominal muscles can change the angle between the baby and the presenting part and the pelvis.

Third, the fetus is overweight. Some mothers have overnutrition during pregnancy, which causes obesity and rapid weight gain in the baby. The fetal head of a giant baby will be larger. When the giant baby is too large and asymmetrical with the pelvis, the fetal head will not enter the pelvis.

Fourth, the habitual posture of expectant mothers in life is directly related to whether the later pregnancy is smooth. If the mother sits in the office for a long time, the baby may not be able to adjust to the best delivery posture in time due to lack of proper exercise. It is recommended that pregnant mothers sit slightly forward during pregnancy, so that the knees can be lower than the hips to reduce pressure, which will help the baby's back turn to the front of you and move down.

When pregnant mothers come to the hospital for their first check-up, gynecologists will ask whether they have had previous childbirth experience. If it is a second childbirth, the abdominal muscles will become relatively looser, making it easier for the baby to enter the pelvis before delivery.

Summary: If the fetus does not enter the pelvis, pregnant mothers should not panic too much. As long as the pregnant woman and fetus are in good condition, the doctor will use some treatments to help the uterus contract and help the fetus enter the pelvis smoothly. In this way, natural vaginal delivery is still possible. If the examination finds that the malposition of the fetus is caused by pathological factors, early detection and early treatment are necessary. If necessary, cesarean section can be used to ensure the safety of the mother and fetus.

How to get the fetus into the pelvis quickly

1. Walking: Walking can help the fetus descend into the pelvis, relax the pelvic ligaments, and prepare for delivery. When walking, it is best for the mother to walk, massage, and talk to the baby. Walking can be arranged twice a day, morning and evening, each time for about 30 minutes, or three times a day, morning, noon, and evening, each time for 20 minutes. It is best to choose a quiet environment for walking, without pollutants around, and do not walk on the roadside.

2. Gymnastics: Prenatal gymnastics is very popular abroad. Gymnastics can not only promote the fetal head into the pelvis, but also increase the toughness and elasticity of the pelvic floor muscles.

3. Pony Stance: Hold the edge of the table with your hands, stand steadily with your feet, slowly bend your knees, lower your pelvis, and naturally spread your legs and knees until they are completely bent. Then, slowly stand up and push up with your feet until your legs and pelvis are both upright. Repeat several times.

4. Leg rowing exercise: Hold the back of the chair with your hands, fix your right leg, and make circles with your left leg. When you are finished, return to the original position, change legs and continue. Do it 5-6 times in the morning and evening.

5. Waist exercise: Hold the back of the chair with your hands, inhale slowly, use your arms to exert force, stand on tiptoe, straighten your waist, keep your lower abdomen close to the back of the chair, then exhale slowly, relax your arms, and return your feet to their original position. Do this 5-6 times in the morning and evening.

6. Pelvic exercise: Get on your hands and knees, inhale and arch your back, exhale, raise your head and lift your upper body as high as possible, repeat 10 times.

7. Pupil muscle exercise: Lie on your back, slowly contract your pussy muscles, pull your buttocks up, count to 5 and then slowly lower yourself, repeat 10 times.

8. Climbing stairs: Many doctors will tell expectant mothers who have passed their due date but have not had any labor yet: "Go climb the stairs!" That's right, climbing stairs can exercise the muscles of the thighs and buttocks, and help the fetus enter the pelvis, so that the first stage of labor can come as soon as possible. Mothers can climb the stairs in the apartment building at home, and find a small hill to walk in the afternoon. If you feel tired, you should rest in time, and pay attention to your feet when going down the stairs and pay attention to safety.
