1.Social factors According to a questionnaire survey on the choice of delivery method of 214 pregnant women in a hospital in Guangdong in 2000, the results showed that only 40.0% of pregnant women had the requirement of vaginal delivery and 60.0% wanted to have a cesarean delivery, among which 25.3% were worried about the pain of delivery, 24.4% were worried about the safety of the fetus, 40.1% were worried about both of the above, and other factors were 10.2% were concerned about the pain of delivery, 24.4% were concerned about the safety of the baby, 40.1% were concerned about both, and 10.2% had other factors. In other words, the total number of women who were worried about labor pains was 65.6%. Many mothers are afraid of labor pains, but they are also afraid of having a cesarean section after a trial of labor, which is “suffering twice”; the public, pregnant women and their families have limited knowledge and misconceptions about the operation, and believe that a cesarean section can be less painful and more intelligent for the fetus; some pregnant women and relatives are superstitious and choose the time of delivery to seek an “auspicious day”. Some pregnant women and their relatives are superstitious and choose the right time to give birth to their babies to get an “auspicious day”; the number of first-time mothers has increased; a couple has only one child and ask the hospital to “guarantee” the absolute safety of the child; due to social and economic development and the general improvement of people’s living standard, the number of huge fetuses has increased, which increases the chance of difficult delivery; multiple abortions before pregnancy As well as the emergence of pregnancy complications, more and more “forced cesarean delivery”. 2, hospital factors Cesarean delivery only takes 30-40 minutes under normal circumstances, while natural delivery medical and nursing staff invest more energy and time and take more risks, but the charges are significantly lower than that of cesarean delivery, and some medical and nursing staff tend to deliver by cesarean, which is also an important reason for the high number of cesarean delivery; some hospitals and departments promote economic contracting, give economic targets, name surgery and special services, etc. A few medical personnel cater to the psychology and wishes of pregnant women and their families to gain favorable impressions in order to improve hospital satisfaction. In addition, due to the increase of prenatal monitoring methods and the uneven level of medical and nursing staff, there is a bias in the diagnosis of monitoring and interference means, and to some extent there is the phenomenon of “over-diagnosis and treatment”; cesarean section technology is becoming more and more mature, resulting in the imbalance of the development of vaginal midwifery technology, especially the young physicians cannot master vaginal midwifery technology. The problems that can be solved by vaginal delivery can only be solved by cesarean section in the end. The number of medical disputes and lawsuits in obstetrics has been at the top of the medical industry, and the expectations of society and families on pregnancy and childbirth are getting higher and higher. In the review process of perinatal deaths, there is a lack of consideration of the problem according to the objective conditions at the time of the incident, but the reverse thinking of “hindsight”: “if we had done a cesarean section, there would not have been a perinatal death”. Some hospitals require pregnant women to choose their own method of delivery and sign for it, equating the most natural method of childbirth, which has been used for thousands of years, with a cesarean section to save the lives of the mother and child, and leaving the choice to the mother and her family, with the rate of cesarean sections increasing as medical personnel become more aware of self-protection.
