Is it serious if fetal heart rate monitoring fails?

Is it serious if fetal heart rate monitoring is unqualified? Regarding this issue, relevant personnel said that everyone should pay attention to two lines when doing fetal heart rate monitoring. The upper line represents the fetal heart rate, and the lower line represents the intrauterine pressure. The fetal heart rate normally fluctuates between 120-160. Is it serious if fetal heart rate monitoring fails?

Please do not worry. Reflective fetal heart monitoring is to continuously monitor the fetal heart rate for 20 minutes. There are at least 3 fetal movements with the fetal heart rate increasing by more than 15 times/minute, which lasts for more than 15 seconds. If the fetus is in a dormant state, it is necessary to increase the monitoring time or wake up the fetus. In practical terms, it is better to do fetal heart rate monitoring during the period when the baby's fetal movement is active.

When doing fetal heart monitoring, everyone should pay attention to two lines. The upper line represents the fetal heart rate, and the lower line represents the intrauterine pressure. The fetal heart rate is normally a wavy straight line, and any fluctuation between 120 and 160 is considered normal. Within 20 minutes of fetal heart monitoring, if the baby's fetal heartbeat fluctuations are within this range, then there is no problem.

However, if the baby's fetal heart rate does not change, or does not move for a long time, this situation is what we often call fetal heart monitoring failure. At this time, the doctor will usually ask you to do fetal heart monitoring again after an hour, or arrange for you to do other tests. If the doctor feels that the baby's condition is not particularly good, he or she may recommend an induced abortion. In fact, everyone can do fetal heart monitoring at home by themselves. You can go to the pharmacy or hospital clinic to buy some related home-use equipment, and check it at home anytime and anywhere, so that you will have a better idea of ​​the situation.

Abnormal fetal heartbeat

The normal heart rate of a fetus is between 120 beats/minute and 160 beats/minute. If the fetal heart rate is <120/minute or >160 beats/minute for more than 10 minutes, it means that the fetal heart rate is abnormal.

During fetal heartbeat monitoring, if an abnormality is found in the fetal heartbeat pattern, it is often used to indicate that the fetal heartbeat is abnormal. In most cases, abnormal fetal heartbeat means that the fetus is suffering from insufficient oxygen in the uterine cavity. The more severe the abnormal fetal heartbeat is, the more severe the fetal intrauterine hypoxia is. However, not all abnormal fetal heartbeat is caused by insufficient oxygen.

In addition to the above-mentioned situations, the condition of the pregnant woman herself also affects the changes in the fetal heartbeat. For example, if the pregnant woman has a fever, the fetal heartbeat will often exceed 160 beats/minute. If the pregnant woman has a relatively hyperactive thyroid hormone, her own heartbeat will be fast, and the fetal heartbeat will also often exceed 160 beats/minute. If the pregnant woman takes some medicines, such as salbutamol for premature babies, or atropine, it can cause the heart rate of both the mother and the child to increase. In addition, in the case of umbilical cord entanglement, the movement of the fetus sometimes aggravates the entanglement and the fetal heartbeat continues to accelerate. This coiling may be transient. If it occurs after 36 weeks, due to the relatively fixed position of the fetus, this entanglement may cause fetal distress or even death.

In addition, after more than 40 weeks of pregnancy, due to the development of the fetal nervous system, the fetal heartbeat may sometimes be less than 120 beats/minute. Therefore, when there is an abnormal fetal heartbeat, it is necessary to carefully analyze the situation and make appropriate judgments and solutions. If there is indeed fetal intrauterine hypoxia, delivery should be performed as soon as possible.
