At nine and a half months of pregnancy, mothers-to-be are truly here, excited and nervous about the moment of delivery. What exactly is the process of childbirth like? What can go wrong? What can you do to cooperate with the birth attendants (doctors, nurses and midwives) to achieve a smooth delivery? …… expectant mothers and fathers usually have a lot of questions about what will happen in the delivery room. Therefore, we would like to present a general article that you can read to help you to have a smooth delivery. The delivery room, like the operating room, is a semi-enclosed room where general staff are not allowed to enter to avoid infection, so expectant mothers and fathers are mystified by the delivery room. Let’s analyze the process of natural childbirth in the delivery room to satisfy the curiosity of expectant mothers and fathers, and to eliminate your nervousness and worries. First, let’s understand normal childbirth. Having a baby is a major event in life and indispensable for human reproduction and survival. In medical terms, childbirth is the process of expulsion of the fetus and its appendages from the mother’s body after 28 weeks (7 months, or 196 days) of pregnancy and beyond. The birth of a child between 28 weeks (7 months, 196 days) and less than 37 full weeks (258 days) is called premature birth; the birth of a child between 37 full weeks and less than 42 full weeks (259-293) is called full-term birth; the birth of a child between 42 full weeks (294 days) and later is called premature birth. Normal childbirth is a natural process in the survival and reproduction of people, the so-called normal birth is a single full-term birth in the process of birth without the need for external force and natural birth. But it does not mean that there is no need for help, to be precise, normal birth should be with the help of midwives, using the new method of midwifery, with a smooth birth, a healthy mother and baby, and no complications (outside of lateral perineal resection). There are three basic conditions to achieve a normal delivery, i.e. sufficient labor force, normal pelvic cavity and normal fetal position with appropriate size fetus, any one of these conditions is not available for a normal delivery. The flow of delivery after the woman enters the delivery room The opening of the cervix The woman is escorted into the delivery room by the nurse when the opening of the uterus is 2-3cm, and the midwife receives the woman, checks the opening of the uterus, listens to the fetal heart rate and does fetal heart monitoring. If the fetal heart monitoring is normal, the fetal heart rate will be checked in the waiting room, and the midwife will check the fetal heart rate and the opening of the cervix regularly (usually every 4 hours before the opening of the cervix is 3cm, and every 1-2 hours after the opening of the cervix is 3cm, which can be adjusted according to the situation) and the fetal head descent. It takes 8 hours on average from labor to the opening of the cervix 3cm, 4 hours from the opening of the cervix 3cm to the full opening of the cervix, and 1-2 hours from the full opening of the cervix to the delivery of the fetus, so it takes about 12-14 hours to deliver a baby. The fetal head should drop continuously during this process, with an average drop of 0.83cm per hour. If the above limit is exceeded by observation, it is abnormal, i.e. beyond the scope of normal delivery, and the midwife should report to the doctor, who will then conduct a thorough examination to find the possible causes and deal with them or observe them, sometimes it may be necessary to change to cesarean delivery. As long as it is within this category, the mother should not be too anxious and adjust her emotions and breathing to facilitate a smooth delivery. Because psycho-psychological factors are also the fourth important factor leading to obstructed labor. Being in a psycho-psychological state of anxiety, anxiety and fear for a long time can lead to weak contractions and fetal distress. If abnormalities are found, the doctor will decide whether to perform a cesarean section. In addition, if abnormal fetal heart monitoring or abnormal amniotic fluid occurs during labor, the midwife should report to the doctor, who will make a decision to continue labor or change to cesarean section after a comprehensive examination. In addition, during the observation of labor, blood pressure should be measured every 4-6 hours and the mother should be allowed to urinate every 2-4 hours. When the opening of the uterus is fully opened (10 cm) for primigravida and 4 cm for transwomen, the mother enters the delivery room from the waiting room and gives birth on the delivery bed, at which time she can use abdominal pressure to help deliver the fetus. After delivery of the fetus, the mother continues to be observed in the delivery room for 2 hours. After delivery of the fetus, the midwife handles the umbilical cord, measures the length and head diameter, weighs the newborn, and makes the mother’s thumbprint and the newborn’s footprint on the neonatal chart. After delivery, the mother is to be observed in the delivery room for 2 hours, depending on whether she will bleed or not, with pressure on the uterus every half hour to promote contraction and observe bleeding. And the baby is allowed to be in contact with the mother’s skin for more than half an hour to attract the nipples. Then only leave the delivery room and go back to the ward to recuperate. How should the mother cooperate with the midwife? If the contractions are not tight during the first stage of labor, you should relax your mind and try to move on the floor or chat with others to distract yourself. Eat and drink some easy-to-digest, nutritious and high-energy food, such as chocolate, as usual. You should also urinate and defecate regularly so that the overstuffed bladder and filled rectum do not affect the descent of the fetus. When there is a break between contractions, try to relax the whole body muscles to rest in order to preserve your strength. If possible, ask the doctor to perform analgesia when the opening of the uterus is 2 cm wide. During the second stage of labor, according to the doctor’s instruction or usual practice, cooperate with the force during contractions. The correct action is to put both legs on the delivery bed, hold the bed handle with both hands, or take the knee position, or take the squatting position. During contractions, first inhale deeply, then hold your breath like defecation and push downward for as long as possible, followed by a deep breath and then a deep breath, then hold your breath and push, so that each contraction with 2 to 3 times the force. Between contractions, relax your whole body, rest quietly and prepare for the next contraction. When the fetus is about to be delivered, you should open your mouth and breathe as requested by the doctor to reduce abdominal pressure and prevent lacerations in the birth canal. Finally, I wish every happy mother-to-be a successful delivery of your baby!
