In the tenth month of pregnancy, every mother is looking forward to the arrival of her baby. Which method of delivery is the best for the mother and the fetus? If you are a healthy mother, you are the right age, your pelvis is normal, there are no medical or surgical complications, your fetus is in a normal position and the right size, you can choose natural childbirth. Natural childbirth on the fetal side: Natural childbirth is the process of delivering a fetus through the vagina. It is a natural physiological phenomenon and the first hurdle of life. With the rhythmic contractions of the uterus after delivery, the fetal thorax receives rhythmic contractions and the fetal lungs rapidly produce an alveolar surface active substance that allows the newborn’s lungs to expand easily and establish spontaneous breathing. During delivery, the fetus is squeezed by the birth canal and mucus from the airway is squeezed out, resulting in a relatively low incidence of neonatal aspiration pneumonia. During delivery, the fetal scalp is compressed and the blood runs slower, which facilitates blood filling, excites the respiratory center and establishes a normal respiratory rhythm. Domestic and international data report that children delivered naturally are better than those delivered by cesarean section in terms of language and social behavior. Natural childbirth for the mother: natural childbirth is a physiological phenomenon, the mother experienced the pain of childbirth can better appreciate the greatness and nobility of motherhood, closer to the mother and child, and also gives the child the first opportunity to exercise. Natural childbirth is less traumatic, safer than caesarean section, less bleeding, quicker recovery after delivery, beneficial for postpartum recovery, and saves economic expenses. However, in recent years, the rate of cesarean delivery has increased dramatically, especially in urban hospitals, to more than 60% in some cases. The pain of childbirth, the nervousness and anxiety of childbirth, the confusion and ignorance of childbirth make too many pregnant women choose to have a cesarean delivery. What are the effects of cesarean delivery on the mother and the fetus? Cesarean delivery on the fetus: Cesarean delivery is the process of removing the fetus by cutting open the uterus through the abdomen. The newborn does not receive rhythmic uterine contractions and is not squeezed through the birth canal, which makes the newborn susceptible to pulmonary complications. Newborns are more likely to grow up with motor incoordination, concentration problems, hyperactivity and other sensory dysfunctions, and are less likely to be emotionally intelligent than children delivered naturally. In addition, cesarean sections sometimes cause fractures in the newborn: clavicle fractures, femur fractures, humerus fractures, skull fractures, and sometimes soft tissue injuries in the newborn due to thin uterine walls or low amniotic fluid. Cesarean section on the mother’s side: Cesarean section is an effective means to solve difficult labor and certain obstetric complications and comorbidities. After all, surgery has its own risks. Only when a pregnant woman has indications for cesarean delivery, such as pelvic abnormality, abnormal fetal position, huge fetus, fetal distress, placenta abruptio, etc., and there are difficulties in natural delivery, will she decide whether to have a cesarean delivery. Cesarean delivery involves many risks in anesthesia and many risks in intraoperative and postoperative period, such as bleeding, intestinal injury, ureteral injury, poor healing of uterine incision or infection, late postpartum hemorrhage, and even removal of uterus and loss of fertility in the future. After surgery, intestinal adhesions, intestinal obstruction, endometriosis, thromboembolism, liquefaction of abdominal incision and infection may occur, and the uterus will be scarred forever, which is a scarred uterus. Therefore, the mother-to-be should choose the delivery method carefully, try to give birth naturally, wait for natural delivery with ease and confidence, and be a happy mother with a normal delivery.
