Any delivery within 38-42 weeks of pregnancy is considered full-term and is normal. If the doctor assesses that there are indications for natural childbirth, natural childbirth can be carried out, but also the following ways to promote childbirth: 1, so that the fetus in the uterus in a normal position: under normal circumstances, the position of the baby in the uterus before delivery, should be head down, facing the pregnant woman, slightly left leaning, this position is the easiest to make the baby descend to the birth canal. If the baby’s fetal position is not correct before delivery, the pregnant woman can lie on the back of the chair, hands and feet on the ground, in a crawling position, or ride across the chair, at least adhere to 20 minutes, so as to correct the bad fetal position; 2, more walking: research has found that activities or standing, sitting, etc. have a certain role in promoting childbirth. More activities such as stair climbing, squatting and leg pressing can promote blood circulation, make more blood flow to the uterus and promote contractions. In addition, standing and other postures can also make the pelvis expand more, more conducive to childbirth; 3, learn breathing: the correct breathing method in labor can accelerate the process of labor, so that the uterus gets enough oxygen to make each contraction effective, pregnant women can contact as appropriate; 4, choose the appropriate environment: the environment also has a certain impact on childbirth, it is recommended that more communication with doctors before delivery, to understand the hospital delivery environment, choose the appropriate 5, relaxed state of mind: if the mother is nervous during childbirth, it will make the uterus oxygen supply obstructed, increasing pain and reducing the efficiency of contractions, so try to maintain a good, relaxed state of mind before delivery. To sum up, if the mother has fetal oxygen deprivation during delivery, at this time can not be delivered smoothly through the vagina, it should be changed to caesarean section.
