How is IVF harm reduction performed

As there are more and more patients suffering from infertility, people's medical technology has begun to develop, so many technologies have been applied to fertility. People have developed in vitro fertilization, and the success rate of in vitro fertilization is now getting higher and higher. However, because multiple embryos need to be implanted, there is a high possibility of multiple births or multiple fetuses being underdeveloped, so a surgical examination is required.

Introduction

With the application of assisted reproductive technologies such as ovulation induction and artificial insemination, on the one hand, it has brought hope of having children to infertile patients, but on the other hand, multiple pregnancies have also increased. Since multiple pregnancies are prone to miscarriage, premature birth, low birth weight, etc., it is difficult to ensure the survival of the fetus, and it increases the complications of pregnant women, seriously affecting the health of pregnant women and fetuses and even endangering their lives. In the past, multiple pregnancies were generally treated with abortion or allowed to develop. However, in recent years, the use of fetal reduction surgery can safely and effectively control the number of fetuses delivered, improve the survival rate of fetuses, and greatly reduce the harm of multiple pregnancies to mothers and babies.

Fetal reduction is the process of injecting potassium chloride into the heart of a fetus that is scheduled to be terminated at 11 weeks of pregnancy, causing its death. A dead fetus remaining in the uterine cavity has no adverse effects on the mother or other fetuses.

Natural fetal reduction results in a "paper-like fetus"

Aunt Wang is a midwife in a remote mountain village in western Hubei. She has been engaged in midwifery for more than 20 years and is very famous within a radius of dozens of miles. Almost all the children in the village are brought into this world by her.

But one day she encountered something strange she had never seen before: Aunt Liu's daughter-in-law was about to give birth, and Aunt Wang was naturally busy all the time, and the child was born smoothly. But when they were cleaning the placenta, they saw another fetus, about the size of a palm, with eyes, nose, hands and feet. However, this fetus was as flat and thin as paper, neither human nor ghost. Everyone present screamed in surprise... After the news of the freak baby spread, there were naturally many rumors in the village. Some said it might be the reincarnation of an elf or monster, and some said it might be a sign of some bloody disaster.

The elderly also mentioned that a similar monster appeared in the village decades ago. Not long after, the Japanese devils entered the village, burned down the entire village, and killed many people. This incident still makes several elders feel scared when they recall it. This time a monster appeared in the village again. Could it be... The village was filled with gloom and everyone was in panic, worrying that some disaster would really befall them. In fact, the freak fetus given birth to by Liu's daughter-in-law is medically called a "paper fetus", a type of natural fetal reduction that mainly occurs in twin or multiple pregnancies. In other words, Liu's daughter-in-law was originally pregnant with twins, one of the fetuses developed normally, while the other did not. The reasons for abnormal development are very complex, with chromosomal abnormalities being the main cause, accounting for more than 50% to 60% of the incidence. This abnormal fetus was estimated to have been eliminated around 12 weeks of gestation due to chromosomal abnormalities and other reasons under Darwin's natural law of "survival of the fittest" and stopped developing from then on. After the fetus dies, it is constantly squeezed by the amniotic sac of a normal pregnant fetus, and some of the soft tissue of the dead fetus is absorbed. By the time a normal fetus is delivered, the dead fetus becomes flat and thin, but the entire outline of the fetus is still clearly visible, so it is called a "paper-like fetus."
