summary

How is abnormal fetal heart rate to return a responsibility? During the clinical care of fetal heart rate, abnormal fetal heart rate figures are found, which are often used to indicate abnormal fetal heart rate. Most cases of abnormal fetal heart rate is on behalf of fetal hypoxia in the uterus. The more serious the abnormal fetal heart rate is, the more severe the fetal hypoxia is. But not all abnormal fetal heart rate is caused by hypoxia.

How is abnormal fetal heart rate to return a responsibility?

In addition to the above situations, the situation of pregnant women also affects the change of fetal heart rate. For example, if pregnant women have fever, the fetal heart rate often exceeds 160 beats / min. if pregnant women have hyperthyroidism, their heart rate is very fast, and the fetal heart rate often exceeds 160 beats / min, if pregnant women take some drugs, such as ritodrine hydrochloride or atropine for premature delivery, Both can cause the heart rate of mother and infant to increase.

In addition, in the case of umbilical cord entanglement, due to the movement of the fetus, sometimes it will aggravate the entanglement, and the fetal heart rate will continue to accelerate. If this happens before 36 weeks, because the fetus is small, the fetus can swim freely in the uterus, and the twining can be transient; If it occurs after 36 weeks, because of the fixed position of the fetus, this kind of entanglement can cause fetal distress or even death.

Slow fetal heart rate may be caused by fetal hypoxia, but sometimes pregnant women take some drugs, such as propranolol, which act on the fetus through the placenta, causing fetal heart rate to slow down. When the fetal heart rate continues to slow, we should pay attention to check whether the fetus has the possibility of congenital heart disease. In addition, after more than 40 weeks of gestation, due to the development of the fetal nervous system, the fetal heart rate can sometimes be lower than 120 beats / min. therefore, when there is abnormal fetal heart rate, it is necessary to carefully analyze the situation, make correct judgment and treatment, and give birth as soon as possible if there is fetal hypoxia.

matters needing attention

If the fetal heart rate beats more than 160 times per minute, or less than 120 times, or the heart rate is irregular, fast and slow, stop and jump, etc., it is abnormal. Pregnant women of 28 weeks of gestation should listen to the fetal heart rate for more than 1 minute each time. If the fetal heart rate is always lower than 120 beats / min or higher than 160 beats / min within 10 minutes, or the fetal heart rate slows down, the reactivity is poor and the fetal movement is reduced after the fetal heart rate accelerates, please see a doctor immediately for examination. It can be seen that pregnant women count fetal movements carefully at home and monitor fetal heart rate carefully, which is helpful to find problems in time and take measures to save the baby's life in time.
