All mothers who are pregnant and preparing for pregnancy want to know whether it is better to have a normal birth or a C-section. Although many mothers are aware of the benefits of normal birth, a large percentage of mothers choose to have a cesarean section due to fear of prenatal pain, so how to choose the right birth method? Let us first understand their respective advantages and disadvantages: a. natural birth natural birth, suitable for the size of the fetus, in the normal force of uterine contractions, after the mother’s appropriate size of the birth canal, the fetus can be born: 1, the advantages: (1) rhythmic contraction and diastole of the uterus during labor, so that the fetal chest also occurred rhythmic diastole, so that the fetal lungs get exercise, for the baby after birth (2) When the fetus is delivered through the mother’s birth canal, the amniotic fluid and mucus absorbed in the uterus can be squeezed out under the effect of compression, thus reducing neonatal complications; (3) During vaginal delivery, the fetal head is engorged by the pelvic floor compression, which provides more benign stimulation to the respiratory center of the brain, making the baby born easy to stimulate breathing and cry loudly; (4) Vaginal delivery can make the birth gate (4) vaginal delivery can make the birth gate dilate greatly, which is conducive to the draining of postpartum dew and faster recovery of the uterus after delivery; (5) some data analysis shows that the children born naturally are more intelligent. (2) postpartum vaginal laxity, uterine bladder prolapse and other sequelae; (3) perineal injury or even infection, vulvar hematoma, etc.; (4) postpartum bleeding due to poor contraction of the uterus, if the postpartum bleeding is uncontrollable, emergency caesarean section is required, and in serious cases, the uterus needs to be removed, or even life-threatening; (5) unsuspected amniotic fluid embolism. (5) Amniotic fluid embolism occurs without warning; (6) Injury to the fetus: if the fetus is difficult to deliver or the mother is exhausted and requires forceps or vacuum suction to assist the delivery, it will cause the fetus to have an enlarged head. The fetus is overweight, which can easily cause difficult shoulder delivery and lead to clavicle fracture or brachial plexus injury in the newborn. Fetal stool is produced in the amniotic fluid, resulting in fetal aspiration syndrome in the newborn. Fetal accidents in the uterus, such as umbilical cord wrapping around the neck, knotting or prolapse, etc. (2) The operation can save the mother and child’s life when the fetus or mother has abnormalities that cannot be delivered vaginally; (4) If there are other diseases in the abdominal cavity, they can be removed together with the operation; (5) The vaginal cavity is not easily removed. (5) The vagina is less likely to be damaged. (2) The average blood loss in caesarean section is more than 300 ml, much more than that in vaginal delivery (100D300 ml); (3) Caesarean section may cause wound infection, intraoperative amniotic fluid tethering, surgical accident, uterine injury and removal; (4) intraoperative anesthesia accident and other unpredictable accidents; (5) intraoperative anesthesia accident and other unpredictable accidents (5) the mother’s recovery after the operation is slow and she is prone to chronic abdominal pain caused by adhesions in the pubic pelvis; (6) cesarean delivery will leave scars on the uterus, which will bring many dangers to future deliveries or abortions; (7) some studies show that babies born by cesarean section have poorer physiological adaptability than those born naturally. The above comparison shows that normal birth is better than cesarean birth, both for the mother and the fetus. But why is the rate of cesarean section still high now? The main reason is that many people lack the correct understanding that cesarean section has anesthesia, which can reduce the pain of contractions during labor. In fact, in addition to the above-mentioned disadvantages, caesarean section also has some long-term complications. A patient, who had a cesarean section 2 years ago, had a small amount of vaginal bleeding 50 days after menopause, and during the examination, it was found that the gestational sac was in the scar of the uterus after the cesarean section, and she was suggested to be hospitalized, but she refused. The hysterectomy was performed in emergency because the pregnancy capsule lodged in the scar, resulting in uterine perforation and hemorrhage! In conclusion, childbirth is a physiological process, and we advocate and encourage natural childbirth, but the choice of the appropriate mode of delivery should take into account both maternal and fetal factors, and women should not blindly insist on normal delivery when a caesarean section is indicated. In addition, in order to have a smooth delivery, mothers should adjust their diet, control the rate of weight gain, exercise appropriately during pregnancy, and have prenatal checkups on time.
