With the liberalization of the “two-child policy”, some eligible couples have started to think about having another one. Not long ago, CCTV investigated the topic of the second child, on whether they want their parents to give themselves another brother or sister, some children said “no, I want you to give me all the love”, “what does it matter to me”, some children even said astonishingly ” Many netizens have lamented that there are “risks” in having a second child! The children’s words may not be taken seriously, but the risk of having a second child is real. The first thing you need to do is to get a good deal on your own. But after the relaxation of the “second child”, not only the pregnant mother herself, some medical risks may also be concentrated. This is why families need to pay attention to this. The policy is open, but the door to pregnancy and childbirth is not unobstructed. The family planning policy began in 1980, according to this projection, the age of many only child has exceeded 33 years old, or even 35 years old, belong to the ranks of senior maternity. The first is that the woman has already given birth once and her chances of conception and postpartum recovery are not as good as before; 2. The chances of ectopic pregnancy, spontaneous abortion, pregnancy complications and fetal birth defects are also increased when giving birth at an advanced age, and the three indicators of premature rupture of amniotic membrane, hyperemesis and preterm delivery are also higher than those of the control group. The first child was born by cesarean section, the second child needs to be beware of “scar pregnancy” According to the relevant data, in China, the rate of cesarean section reached 70-80%, the first child was born by cesarean section of women in the pregnancy of the second child, have to face the risk of “scar pregnancy The risk of “scar pregnancy”. Modern obstetrics experts explain that the so-called “scar pregnancy”, is the first child produced by the scar, may be with the second pregnancy the uterus again gradually thinner, if the scar is too thin may be squeezed out, serious hemorrhage, the life of the mother and baby at risk. In addition, the incidence of placenta praevia is significantly higher in women with scarred uterus, and if the placenta happens to be attached to the scar, it becomes an aggressive placenta praevia, and there is a risk of more dangerous hemorrhage during pregnancy. Therefore, about 50 days after a woman who has had a cesarean delivery becomes pregnant again, she should have another ultrasound to see the location of the embryo sac and the scar and to rule out all risks. In addition to the above two more prominent risks, there are many sudden health threats associated with having a second child. Therefore, pregnant women with two children must pay more attention to prenatal, pregnancy and postnatal checkups and health care. 1. Do a good job in prenatal checkups. The second child pregnant women should shorten the interval between examinations, from the diagnosis of pregnancy, once every half month, and pay special attention to blood pressure and urine examination, in order to timely detection of hyperemesis. From the third month onwards, check once a week, and if abnormal fetal position is found, you should ask the doctor to take timely and effective measures to correct it. 2. Be more cautious than normal pregnant women throughout pregnancy and strengthen health care in terms of clothing, food, housing and transportation. In terms of diet, it is necessary to ensure adequate nutrition supply and not to eat too much, and to carry out physical activities appropriately to prevent the fetus from becoming too large. 3. Pay attention to mental health during pregnancy. Some second-trimester pregnant women are worried about the problems that will occur during delivery after their pregnancy is diagnosed, and this bad psychology is bad for both the pregnant woman and the fetus. In modern medical conditions, as long as pregnant women actively cooperate with doctors and follow their instructions, they can deliver safely. 4. To ensure the safety of mother and child. Pregnant women with second child should be admitted to hospital for delivery a few days to ten days earlier than normal pregnant women, the specific time can be decided by the doctor according to the different conditions of pregnant women. Although there are many risks, with the advancement of medical technology, more and more risk factors can be detected through standardized and meticulous pre-conception and pregnancy check-ups. Therefore, it is possible to reduce the risk of having a second child at an advanced age by being fully prepared and with standardized pre-conception and pregnancy checkups.
