The birth canal, the passage through which a baby is born! Part of the birth canal is the \”osseous birth canal\” composed of bones, and the other part is the \”soft birth canal\” composed of muscles and ligaments, which refers to the part from the cervix below the uterus to the vaginal outlet. The uterine opening is closed before labor begins. As labor progresses, the connections between ligaments and bones loosen and soften. Once labor begins, the birth canal opens enough to allow the baby to pass. size. A good birth canal condition is that the bony birth canal is not narrow, the soft birth canal is normal, and the stretch force is good.
The fetus rotates out of the birth canal. After the cervix is fully opened, the first stage of labor ends and the second stage of labor enters. This period is when the fetus passes through the birth canal and is delivered. In order for the fetus to be born smoothly, the mother exerts more force, and the fetus passes through the birth canal with the help of labor pain and the strength of the mother. However, even if the soft birth canal is fully opened, the bony birth canal cannot expand significantly and is slightly curved. The fetus adapts to the shape of the bony birth canal, changes the direction of its body, and rotates during delivery.
Fetus works with you through childbirth!
Fetal size affects normal delivery. During delivery, the size of the fetus is one of the important factors that determines the difficulty of delivery. If the baby\’s head is larger than the bony birth canal, the delivery will not go smoothly. This misalignment is called \”fetal pelvic asymmetry\” and can cause difficulty in delivery. The fetal head is the largest part of the fetal body and the most difficult part for the fetus to pass through the birth canal.
The fetal position is improper. The position of the umbilical cord around the neck and the fetus in the uterus is the fetal position. The fetal position during normal delivery is head down and buttocks up. Other fetal positions, such as breech position, single breech position, total breech position, knee position, foot position, transverse position, etc., will affect normal delivery, and the doctor may recommend you to have a cesarean section. In addition to abnormal fetal position, fetal factors also include the umbilical cord wrapping around the neck or placenta previa, etc., which will affect normal delivery. During pregnancy, you need to pay attention to fetal movements and decide the mode of delivery based on the actual situation.
Productivity, the driving force behind normal childbirth!
What is productivity? The force that forces the fetus and placenta to separate from the uterus is called productivity, which includes uterine contractility (that is, uterine contraction force), abdominal muscle and diaphragm contraction force, etc. Among them, uterine contraction force is the most important productivity after childbirth. Without it, there will be no birth. Cervical dilatation, descending presentation, and delivery of the placenta may occur. Productivity is relatively adjustable during childbirth. It is recommended that you ensure a regular life and a good mental state during pregnancy, and face childbirth with peace of mind.
What is contraction fatigue? Uterine contractions after labor put a certain amount of pressure on the fetus, and this pressure will increase as the labor process progresses. If a pregnant mother feels too nervous about childbirth, the uterine contraction pressure will decrease in the early stages of labor, slowing down the progress of labor, which is called primary uterine atony. When there are abnormalities in the birth canal or the fetus during delivery, it will hinder the delivery of the fetus and cause dystocia. In order to overcome the obstruction, the uterine contractility first increases, and then gradually weakens due to fatigue, resulting in secondary uterine atony. Multiple pregnancy, excessive fetal size, polyhydramnios, etc. can also cause excessive uterine muscle fiber.Expansion and loss of normal contractility.
Work hard for a safe and smooth delivery
Gymnastics during pregnancy and prenatal period can increase the tension and elasticity of abdominal muscles, back muscles and pelvic floor muscles, soften joints and ligaments, help muscles relax during delivery, reduce birth canal resistance, and make the birth canal smooth. The fetus passes through the birth canal faster. Conducive to normal delivery and postpartum recovery!
Especially in the third trimester of pregnancy, you can learn more about childbirth, relieve the stress and fear of childbirth, and make you calm and brave.
A few days before the expected date of delivery, arrange your diet and daily life after hospitalization, and eat, drink, defecate, and sleep on time. Uterine contractions consume a lot of physical energy. Women should replenish energy and water in time to maintain good physical strength in order to successfully complete delivery. Pay special attention to energy replenishment before delivery. Expectant fathers should also provide strong spiritual and material support.
If you are giving birth for the first time, hiring a doula is a good choice. A doula can comfort and guide you throughout the birth process and give you emotional comfort. Data shows that doulas can effectively shorten labor!
