The Role of Fetal Heart Monitoring
Fetal heart rate monitoring is usually self-monitoring after 12 weeks of gestation. Fetal heart rate monitoring during pregnancy is a very important check-up item in the third trimester. It is also the main detection method to correctly evaluate the fetal intrauterine condition. It is useful for early detection of abnormal fetal heart Timely treatment plays an important role in reducing perinatal mortality.
1. Application of fetal heart rate monitoring can understand the reserve capacity of the fetus, understand the status of the fetus in the uterus, detect fetal hypoxia in time, and make an early diagnosis of fetal distress. The oxygen demand of pregnant women at the end of pregnancy increases. As the fetus grows, the space for the fetus in the uterus becomes smaller, and the chance of umbilical cord compression increases, which may lead to fetal distress. The slow fetal heart rate may be caused by hypoxia of the fetus, but sometimes pregnant women take certain drugs, and the drugs act on the fetus through the placenta, causing the fetal heart rate to slow down. When the fetal heart rate continues to slow down, it is necessary to pay attention to check whether the fetus may have congenital heart disease.
2. Uterine contractions during labor can reduce the blood volume of the uterus and placenta and affect the exchange of blood gas between mother and child. With each contraction, the fetus will be tested for hypoxia. Therefore, fetal heart rate monitoring before delivery can detect fetal distress in time. Active treatment such as oxygen inhalation or changing body position can improve the hypoxic state and reduce neonatal asphyxia and mortality.
