Ladies and gentlemen, in obstetric clinical practice, we have too many medical interventions, which have artificially led to an unreasonable rise in cesarean deliveries; we have too many contradictory recommendations that leave mothers and fathers-to-be in the dark. In fact, pregnancy and childbirth are in most cases physiological processes, not that scary, and we doctors should not have so many interventions. I once said that the best obstetrician should see more, listen more, talk more, and do less. Being able to “tie your hands” and talk the baby out with one mouth is the highest level of obstetrician. In order to give mothers-to-be a better idea of what to choose, I would like to summarize some of my recommendations for mothers-to-be during pregnancy and delivery for your reference. Most of the recommendations below are based on evidence-based medical evidence, while a few are my expert opinion. I will write an article to explain each recommendation according to the actual situation. 2. TORCH screening is not routinely recommended, but is recommended only for some high-risk groups, preferably before pregnancy and secondarily during early pregnancy. Routine measurement of progesterone levels is not recommended to guide early pregnancy preservation. 4. bed rest is not recommended for fetal preservation. 5. oral or intramuscular progesterone is not recommended for fetal preservation. 6. screening and treatment of ABO blood group incompatibility is not recommended. 7. Down’s syndrome screening is recommended, especially in early pregnancy. 8. ultrasound screening for large fetal malformations is recommended. 9. calcium supplementation is recommended for most mothers-to-be from the middle of pregnancy. (except for those with adequate calcium intake in the diet) 10.Recommended iron supplementation for nearly half of the mothers-to-be (determined by routine blood test results) 11.Not routinely recommended supplementation with other “nutritional drugs or added ingredients” except calcium and iron 12.Routinely recommended moderate exercise and diet control during pregnancy 13.Encourage normal delivery, recommend free position for delivery and free position for delivery 14.Not recommended to perform perineal scalpel during vaginal delivery 15.Routinely recommended to breastfeed for 4-6 months after delivery
