Prenatal examination is a very important part of pregnancy. For every pregnant mother, prenatal examination can help her better understand the health of herself and the fetus, especially in the late stages of pregnancy. Fetal monitoring is particularly important, but there are always pregnant women who fail to pass the fetal monitoring. So, what are the reasons for the failure of fetal monitoring?
Abnormal fetal heart rate monitoring is often a sign of poor fetal reserve in the uterus. If the fetal monitoring is not up to standard, it is because the baby is afraid of experiencing hypoxia. The reason for the baby's hypoxia is generally the bad intrauterine environment, or the baby has umbilical cord around the neck, umbilical cord knot, pregnancy diabetes, oligohydramnios or pregnancy hypertension, etc., which leads to the baby's bad intrauterine situation, which may lead to poor fetal heart monitoring.
If repeated monitoring of fetal heart rate does not meet the standard, it is necessary to undergo color ultrasound examination to see if the biophysical score shows that the baby is truly experiencing hypoxia. If the baby really lacks oxygen, it is necessary to consider terminating the pregnancy early and allowing the baby to come out. Because if the baby stays in the uterus, there is a possibility of fetal death.
Under normal circumstances, after fetal movement, the fetal heart rate will increase by 10-25 beats per minute, and the baseline variation of fetal heart rate should be around 0-6 beats per minute, so it should be checked again. In addition, the number of fetal movements can be counted by oneself, and usually the number of fetal movements in an hour should not be less than 5 times. If it is late deceleration or a biophysical score below 4, it must be dealt with as soon as possible.
