The beginning of labor: How labor begins is still not fully understood, except that the labor pains are not neurological, but are caused by hormones in the mother’s body. When the fetus grows in the mother’s body to the point where it is ready to be born, it sends out a hormonal signal for labor, and the mother’s body receives this hormonal signal to intensify the action of the hormones that make the uterus contract, thus causing the uterus to contract and labor to begin. Generally speaking. The onset of labor is marked by regular uterine contractions that occur once every 5 to 6 minutes, accompanied by the progressive disappearance of the cervical canal and dilatation of the uterine opening, and the descent of the fetal previa (head). The clinical course of labor: the first stage (called the first stage of labor, i.e. the period of dilatation of the uterine orifice, usually 11 to 12 hours for first-time mothers), the uterus emits strong contractions, the fetus is forced to move in the direction of the birth canal, the cervical canal slowly shortens, disappears and dilates, the fetus descends towards the pelvis, when the uterine orifice opens to 10 cm, the fetus passes through this opening and the head moves from the uterus towards the vagina); the second stage (the second stage) The second stage of labor is the period of fetal delivery, usually 1 to 2 hours for first-time mothers and 0.5 to 1 hour for women in labor, when the fetal head rotates in the narrow birth canal of the pelvis and descends along the birth canal due to the regular contractions of the uterus. The intense skin stimulation received during the passage through the birth canal awakens the respiratory center of the brain, which starts to prepare the lungs for breathing. During this period, the mother also works with the fluctuations of the labor pains, sometimes with force and sometimes with rest, which can help the fetus to enter the birth canal smoothly and finally come out through the vagina to meet the parents); the third period (called placenta delivery period, after the fetus is delivered, the uterus contracts again, causing the placenta to peel off from the uterine wall and then eliminated from the body, usually lasting 15 to 30 minutes). In the fourth stage, the mother stays in the delivery room for 2 hours after delivery to observe the uterine contractions, vaginal bleeding and vital signs. Pregnant mothers should adjust the psychology of childbirth: as the delivery date approaches, most first-time mothers are getting more and more apprehensive inside, thinking too much about the pain of childbirth, worrying that the delivery will not go well, worrying about the unhealthy fetus, and some are also worried about the sex of the fetus, making themselves terrified all day long, which is very unfavorable to the fetus. On the one hand, the anxiety of pregnant women will lead to hormonal changes in the mother’s body, resulting in adverse stimulation of the fetus, on the other hand, the nervous tension that comes with anxiety and fear often produces many uncomfortable feelings, making pregnant women’s muscles tense and exhausted, which leads to weak uterine contractions during labor, prolonged labor and labor stoppage, resulting in obstructed labor, intrauterine distress, lack of oxygen resulting in fetal brain damage This can affect the intelligence of the fetus and even endanger the life of the fetus. It is very necessary to be psychologically prepared before delivery, pregnant women can read some books about childbirth, to understand the knowledge of childbirth, to be well informed; adjust their mindset, let themselves be full of confidence and pride, to strengthen the hint of happiness, to think of creating a new life is how happy and joyful, this sense of happiness and joy can make your body and spirit in the best condition, so that you away from depression and tension, believe that you are capable of this mission. Believe that you are capable of this mission; when the bout of pain, pregnant women will think of this pain is their baby breaking through the layers of resistance to run to the light of the world and the sound of rescue, then you as a mother will be full of confidence and love to help his arrival. Pregnant mothers cooperate with the birth: in the process of delivery, the uterus contraction in order to make the birth canal expand little by little, which takes a certain amount of time, during this time, the resistance generated by the maternal birth canal and the uterine contraction to help the power of the fetus forward interact, bringing great discomfort to the mother, if the pregnant woman is too afraid, nervous and anxious, may cause the prolongation of labor and stop, the consequences are very terrible, therefore Therefore, in addition to being psychologically prepared, pregnant women must understand the knowledge about childbirth and actively cooperate with the doctor to help the fetus to be delivered smoothly. During the first stage of labor, the regular contraction of the uterus once every 2-3 minutes will cause paroxysmal pain in the lower abdomen of the pregnant woman, if the pregnant woman cannot cooperate, shouting or holding her breath too early will make the pain stronger and prevent the progress of labor, which will prolong the labor, and also consume the physical energy of the pregnant woman and affect the force of labor. So the pregnant woman should try her best to stay calm, relax, go with the flow, lie on her left side, let her whole body muscles relax, take deep breaths during each contraction, breathe in slowly after the contraction passes, and then take deep breaths again. In the second stage of labor, pregnant women should take the initiative to help the fetus force, participate in the work of the uterus, help the fetus to cross the barrier, the specific practice is: when the contraction is coming pregnant women breathe hard, shut up and inhale deeply when the contraction comes, then hold your breath and contract the abdominal muscles, downward force, help the fetus to move forward, in between each contraction, pregnant women should seize the time to relax the muscles, rest, accumulate strength, for the next uterus When the fetal head is about to be delivered, you should actively cooperate with the midwife’s instructions not to push harder to avoid tearing the birth canal, and with the first loud cry of the fetus, the second stage of labor is over. The third stage of labor is the period of placenta delivery, after the delivery of the fetus, the uterus contracted again, so that the placenta peeled off from the uterine wall, and then eliminated from the body, at this time, pregnant women can help the placenta elimination with appropriate force, after the elimination of the placenta, labor is completely over.
