Effect of test tube baby on multiple pregnancy
IVF technology is a kind of assisted reproductive technology, which achieves fertility through in vitro fertilization and embryo transfer. In the process of IVF, sometimes multiple pregnancy occurs, that is, the fertilized egg develops into two or more embryos in the uterus. The impact of multiple pregnancy on IVF is a topic of great concern. This article will analyze the impact of IVF on multiple pregnancy from four aspects: pregnancy risk, pregnancy complications, embryo selection and child health.
1. Pregnancy risk
Multiple pregnancy has a higher risk than single pregnancy. Multiple pregnancy may lead to premature delivery, anemia, hypertension, diabetes, infection and other complications. Multiple pregnancy also increases the risk of placental abruption, which poses a threat to the life safety of both the fetus and the mother. In addition, multiple pregnancy may also cause pregnancy complications, such as polyhydramnios, intrauterine growth restriction of fetus, etc., which make the pregnant women with multiple pregnancy need more close monitoring and nursing.
However, through reasonable prevention and treatment measures, the pregnancy risk of many multiple pregnancies can be controlled. Pregnant women should have regular prenatal examination, and pay close attention to weight control, nutrition intake, rest and avoiding fatigue during pregnancy. Doctors will also develop personalized monitoring and management plans for pregnant women according to specific conditions to reduce pregnancy risks.
2. Complications during pregnancy and childbirth
Multiple pregnancy increases the risk of complications during pregnancy and childbirth. For example, the space of the fetus in the uterus of multiple pregnancy is relatively limited, which can easily lead to placental abruption, fetal distress, intrauterine growth retardation and other complications. Multiple pregnancy also makes pregnant women more prone to overload and fatigue, increasing the risk of complications during delivery, such as dystocia and postpartum hemorrhage.
In order to reduce the risk of complications, pregnant women with multiple pregnancies need more frequent prenatal examinations, including fetal heart rate monitoring, amniotic fluid index evaluation, fetal weight estimation, etc. Doctors will closely monitor the status of pregnant women and fetuses, and timely detect and deal with possible complications. Sometimes, in order to reduce the burden and risk of pregnant women, doctors may choose cesarean section in advance.
3. Embryo selection
Before IVF egg transfer, doctors usually cultivate multiple embryos in the laboratory. In the case of multiple pregnancy, the number of fertilized eggs is more, which also means that the importance of embryo selection is more prominent. Embryo selection is one of the keys to the success rate of IVF.
Generally, doctors will evaluate the embryo according to its appearance, development status, chromosome structure and other factors to select the embryo that is most likely to succeed in pregnancy and develop healthily. However, the choice of multiple pregnancy is more complex, requiring doctors and patients to make joint decisions. They need to take into account the risk of multiple pregnancy and the physical condition of pregnant women, and try to reduce the problems and risks that patients may face after receiving multiple pregnancy on the premise of ensuring the quality of embryos.
4. Children's health
Multiple pregnancy may have some impact on children's health. Multiple birth babies have a higher probability of low birth weight and premature delivery, which increases the possibility that babies need special care after birth. The pathological status of multiple births is complex, which may lead to dyspnea syndrome, neonatal jaundice, anemia and other problems.
However, with the progress of modern medical technology, the care and management of multiple births are also constantly improving. Many hospitals have special care wards to provide all-weather care and monitoring for premature and multiple births. The doctor will develop a personalized care plan to ensure the best medical care for multiple births.
summary
The influence of IVF on multiple pregnancy is a complex and multifaceted problem. Multiple pregnancy increases the pregnancy risk and the incidence of complications of pregnant women, puts forward higher requirements for embryo selection, and also has a certain impact on children's health. However, the progress of modern medical technology and reasonable nursing management can reduce the risk of multiple pregnancy, improve the success rate of test tube babies, and provide better protection for the health of multiple babies.
