Fetal movement is one of the signs showing the health of the fetus. A decrease in the number of pregnancy cycles can be an indicator of poor fetal health. When the fetus is not mechanical or the fetus is weak, it may be due to fetal failure or fetal death.
To monitor fetal movements, the mother must pay attention and have the sensitivity to recognize the mechanical fetus. These are movements that are like tapping sounds against the abdominal wall that is deflected or distorted to one side. It is not easy to realize this but mothers must learn to recognize, count and track fetal movements every day.
Fetal health is reflected in fetal movements as follows:
When there are more than 4 movements in 30 minutes, 3 times in a day - this is a sign of good fetal development If the fetus moves less than 4 times, Pregnant women need to lie down and count fetal movements for one hour, or 2-4 hours. If there are more than 4 fetal movements in 1 hour, the fetus is healthy. If there are more than 10 fetal movements in 4 hours, continue counting 3 times in a day (fetus is healthy). If in 4 hours there are less than 10 fetal movements, or all fetal movements are weak, the mother needs to be hospitalized for further fetal monitoring by other methods. Pregnant women need to be equipped with knowledge about monitoring signs that the fetus is developing well or having problems in order to promptly solve and intervene, combined with periodic antenatal check-ups to have evaluations about pregnancy. development status of the fetus in the most comprehensive and accurate way.
