In the early stages of pregnancy, a number of adverse factors can cause fetal death in utero. When fetal death occurs, the pregnant woman may experience a series of clinical manifestations. When fetal death has just occurred, some pregnant women may have no obvious symptoms. As the time of fetal death increases, some clinical symptoms may appear. The first is the loss of conscious fetal movement. In the fourth month of pregnancy, most pregnant women can feel the fetal movement in the uterus. After the fetal death, the fetal movement disappears. The second symptom is fever. The fetus is not immediately expelled through the vagina after death. The dead fetus will produce toxic substances, and when the toxic substances enter the mother’s blood circulation, it can cause fever in pregnant women. In this case, the only way to solve the fever is to expel the dead fetus from the mother’s body as soon as possible. Finally, if the dead fetus stays in the uterus for a long time, it will further cause coagulation dysfunction of the pregnant woman, and in serious cases, it will complicate diffuse intravascular coagulation and kidney function damage. After serious complications, the pregnant woman will bleed more than once, seriously endangering maternal life. It is recommended that the pregnant woman should seek immediate medical attention at the local hospital to induce labor to extract the dead fetus as soon as possible after the fetus is found dead. To avoid serious complications. The clinical manifestations of a pregnant woman after a stillbirth indicate the severity of the disease and need to be taken seriously by the pregnant woman.
