With the increasing pace of life and the pressure of life, more and more women put their energy on the workplace, resulting in late marriage and childbirth, which makes the number of senior pregnant women increase year by year. Usually, the medical term for pregnant women over 35 years old is senior pregnant women; after 35 years old, those who are giving birth for the first time are called senior primigravida. The first time a woman is born after 35 years old, the incidence of breech delivery, surgical delivery and congenital stupidity is higher. In addition, the pelvis and ligaments of pregnant women at this age are degenerating, the soft birth canal is less elastic, and the contraction of the uterus is weakened, which can easily lead to prolonged labor and difficult delivery, resulting in fetal birth injury and asphyxia. In addition, there are more pregnancy complications and complications in older women than in younger women, the most common ones being pregnancy-related heart disease, gestational hypertension syndrome and gestational diabetes. The ability to conceive is generally less in advanced women, and some of them are more likely to miscarry even if they do conceive. According to Chinese medicine, “the kidney is the master of reproduction” and “the kidney is the basis of fetus”, and the yin and yang of the kidney is the basis of conception. The older women are prone to liver and blood deficiency, Qi and blood imbalance, plus the desire for a child, irritability and anxiety, liver depression, it will be more difficult to conceive. Older pregnant women are prone to miscarriage because they are older and prone to deficiency of kidney qi or qi and blood. The kidney deficiency fetal loss of the system, the lack of Qi and blood fetal loss of carry nourishment, or because of the Qi and blood is not regulated, the operation is not smooth, can lead to fetal death, or fetal atrophy does not grow, or miscarriage. 2, senior pregnant women before and after pregnancy precautions (1) pre-conception preparation senior pregnant women should adjust their bodies to the best condition before pregnancy, which makes adjusting menstruation and leucorrhea is particularly important. By adjusting menstruation, we mean to make the menstruation time regular, the length of the period appropriate, and the volume of the period normal, because the low volume of the period may be too thin endometrium, which will make it difficult for the fertilized egg to be implanted. In addition, the shade of blood and menstrual pain are within the scope of menstrual regulation. Regulating the leucorrhea means adjusting the vaginal discharge. Too much discharge is a sign of body wetness, which can cause infertility; too little can cause vaginal dryness, making intercourse difficult and natural conception difficult. Before conception, both spouses should go to a regular hospital for a physical examination to get a comprehensive understanding of their health, including nutrition, development, and the presence of anemia, hypertension, nephritis, hepatitis, diabetes, etc. During the perinatal period (3 to 6 months before pregnancy) both men and women should maintain their physical and mental health, and should not conceive under the condition of high work pressure, frequent drinking and smoking. Pregnant women should take folic acid orally 3 months in advance to avoid fetal neurological development disorders. If you do not take folic acid in time before pregnancy, you should continue to take supplement after pregnancy until 12 weeks of pregnancy. (2) Attention during pregnancy In early pregnancy, avoid bacterial and viral infections, do not take drugs indiscriminately, and keep a good mood and do not be too nervous or worried. In the first trimester, it is better not to use cosmetics containing lead and mercury, go to public places less often, avoid radiation exposure and infections, and prevent viral infections such as rubella, mumps, influenza and herpes simplex, otherwise it will greatly increase the incidence of fetal malformations. As for diet, it is recommended to have high protein, low fat and mild food. The food items such as tea, wine, cigarettes, coffee, and alcohol and caffeine are not suitable. If you need to take tonic for fetus and nourishment, you should take tonic according to your own constitution’s heat and cold, and it is better to consult a herbalist. An ultrasound should be performed at 12 and 20 weeks of pregnancy to see if the fetus has any abnormal development. A fetoprotein test is performed at 16 to 20 weeks for timely diagnosis of neurological deficiency, Down’s syndrome, kidney and liver diseases. Amniocentesis can be done after 20 weeks of pregnancy to obtain the number of chromosomes directly, and based on the test results, you can know if the fetus has any abnormalities. This test has a 0.5% chance of causing a miscarriage as a result. In the seventh or eighth month of pregnancy, the fetal movement count should be performed for one to three hours a day to keep track of the development of the fetus so as to avoid adverse consequences if problems are not informed to the doctor in time. In addition, it is important to pay more attention to indicators such as blood sugar and blood pressure. Advanced maternal age is prone to combined heart disease of pregnancy, gestational hypertension syndrome and gestational diabetes. As the blood volume in a pregnant woman’s body increases significantly compared to the non-pregnant period, the burden on the heart increases. Pregnant women who already have heart disease are likely to have to terminate their pregnancy early because they cannot tolerate it. The difficulty of natural childbirth for older women is greater, which may lead to prolonged labor and even obstructed labor, fetal birth injury and asphyxia, so 90% of older women will choose to have a cesarean delivery. However, cesarean delivery is after all a pathological delivery, and the woman’s recovery after delivery is slow, so the older women who choose cesarean delivery must be well prepared physically and psychologically. As women’s muscles are in a downward trend after the age of 35, kidney deficiency and liver depression combined with Qi and blood imbalance are more likely to lead to difficult pregnancy, miscarriage, and increased risk of fetal malformation incidence and pregnancy complications. Therefore, it is recommended that women try not to become pregnant at an advanced age.
