Digital movement is the simplest and economical test method of the condition in the palace. Although it is simple, many expectant mothers still have a lot of confusion.Let’s answer them one by one.
What is fetal movement?
The fetal activity in the uterus is called fetal movement (FM).You can move, swing, fetal head and carcass rotation, rolling or high frequency exercise for fetal limbs.
What is the relationship between fetal movement and fetus?
Fetal movement is a good manifestation of the fetal condition.As early as the 1940s, people believed that the fetal movement was directly related to whether the fetal safety was directly related.Later, people gradually confirmed that the fetal movement was related to the supply of blood and oxygen in the uterus, and the latter was directly affected by the placenta function.When the placental function is poor, the fetal movement decreases or even disappears.
How to monitor fetal movements?
The fetal movement can be felt by the pregnant woman themselves, and it can be touched, heard, or even seen, or recorded by the instrument to the fetal movement.Fetal movement is an important indicator of fetal safety.
When can I feel the fetal movement?
In normal pregnancy, pregnant women start to feel fetal movement from 18 weeks to 20 weeks.Initially, the fetal movement is intermittent, weak, and it is not easy to distinguish between intestinal peristalsis, and gradually increases with the continued fetal movement of pregnancy.The fetal motion counting has changed during different periods of pregnancy, different time of day and night, and different physiological conditions of the fetus.
How many times are the fetal movement?
At 20 weeks of pregnancy, the fetal movement is about 200 times/day. With the increase of the gestational week, the fetal movement gradually increases. At the peak of 29 to 32 weeks of pregnancy, there have been records that can reach 757 times/day.After 38 weeks of pregnancy, the fetal movement decreased by the first exposure of the fetus, with an average of 282 times per day.The fetal movement decreases significantly during the expiration.The physiological sleep cycle at the end of pregnancy is relatively obvious, and the periodicity of fetal movement is also obvious. Generally, it is generally uniform at 8 am to 12 am. It is minimized from 2 pm to 3 pm.When pregnant women are resting, due to the relaxation of the abdominal wall muscles, it is more sensitive to fetal movement.Under normal circumstances, the number of fetal movements is about 30 weeks to 40 weeks a day. The difference between individual differences and counting is large. Each pregnant woman has its own rules of fetal movement.
How do you count the fetal movement?
The fetal movement count should generally start from 28 weeks of pregnancy, record once a week at the beginning, and record twice a week at 32 to 36 weeks of pregnancy. After 36 weeks of pregnancy, the fetal movement count is performed in a fixed time every day, mid -to -middle, and evening.After the L -hour fetal movement count, the sum of the 3 times by 4, the number of fetal movements of 12 hours is obtained. If the number of fetal movements of 1 hour is found <3 times, the number of fetal movements of 6 hours or 12 hours should be recorded continuously.Under normal circumstances, the number of fetal movements within 12 hours is ≥30 times.
What is a decrease in fetal movement?
The cumulative fetal movement within 12 hours is less than 10 or ≤3 times/h or daily decreased by more than 50 %, indicating that the fetus is hypoxic, and the internal distress of the fetus should be considered.In high -risk pregnancy such as pregnancy high, expired pregnancy, and intrauterine development (IUGR), the fetal movement can be reduced before the fetal heart rate affects the fetal heart rate.What needs to be emphasized is that the number of fetal movements caused by sedatives or magnesium sulfate should be excluded or temporarily disappeared; too small fetus, excessive amniotic fluid, and obesity of pregnant women can affect the misdiagnosis of fetal movement abnormalities caused by abnormal number of fetal movements.Essence
What is fetal movement sharply?
In pregnancy, if pregnant women find that fetal activity suddenly increases during the conventional fetal movement monitoring process, it is called a sharp fetal movement.The fetus stops after a sharp activity, and often indicates that the fetus is hypoxia and dies.Most of the causes of fetal movement are mostly due to the pressure of umbilical cord pressure and premature placental peeling, which causes insufficient blood supply to the fetus or ending the fetal acute hypoxia.If the pressure factor of the umbilical cord is relieved or lifted, the fetal movement can be restored to normal; on the contrary, the blood supply of the fetus continues to be insufficient, and the fetal movement cannot be restored or stopped, and the fetal dead palace occurs.
