Factors that affect childbirth

There are many factors that affect childbirth. Pregnant women should also strengthen their physical exercise and improve their physical fitness so that they will have enough strength during childbirth. Of course, they should also pay attention to rest and avoid overwork. The size of the fetus is also an important factor affecting delivery. Due to the high living standards of people, the fetuses are relatively large, so natural delivery is more difficult. Let us now take a closer look at the factors that affect childbirth.

1. Productivity

Labor force refers to the force that pushes the fetus and its appendages out of the uterine cavity, including main force and auxiliary force. The main force is the contraction of the uterus, which runs through the entire process of delivery; the auxiliary force is the contraction of the abdominal wall muscles, diaphragm and levator ani muscles, which only appear in the second and third stages of labor to cooperate with the main force.

2. Birth Canal

The birth canal is the channel through which the fetus is delivered, which is divided into bony birth canal and soft birth canal.

1. The bony birth canal refers to the true pelvis. During the delivery process, the size and shape of the bony birth canal are closely related to delivery.

2. The soft birth canal is a curved tube formed by the lower segment of the uterus, cervix, vagina and soft tissue of the pelvic floor.

3. Fetus

1. Fetal size: During the delivery process, fetal size is one of the important factors that determine the difficulty of delivery.

2. Fetal position: Because the birth canal is a longitudinal tube, only in longitudinal delivery will the longitudinal axis of the fetus and the sacral axis pass through the birth canal, which is easier to deliver than breech presentation, which will cause dystocia.

3. Fetal malformation: Some developmental abnormalities such as hydrocephalus and conjoined twins may cause dystocia due to the large fetal head or body.

Psychological factors of parturients

Although childbirth is a physiological phenomenon, it is indeed a long-lasting and intense stressor for the mother. The mother's mental and psychological factors can affect the body's internal balance, adaptability and health.

The first is labor force, which refers to the force with which the baby and its appendages are forced out of the uterus.

The second is the birth canal, which refers to the channel through which the baby comes out of the uterus. This is related to the pelvis. The doctor will help determine whether a natural birth is possible based on the shape and size of the pelvis.

The third factor is the fetus, the size of the fetus, whether the fetal position is transverse, and whether there is placenta previa.

The fourth factor is psychological factors, which is also related to personal mentality. Expectant mothers should relax and stay relaxed.
