Diagnosis of fetal distress?

summary

Fetal distress is also known as fetal intrauterine hypoxia, which is more common. After the occurrence of fetal distress, there will be many symptoms, the main symptoms are three kinds, one is fetal heart rate change, one is growth arrest, the other is abnormal fetal movement. Once these main manifestations of fetal distress appear, we must actively deal with them. Diagnosis of fetal distress? Diagnosis of fetal distress?

Diagnosis of fetal distress?

Calculation method of fetal movement: one hour in the morning, one hour in the middle and one hour in the evening, more than three times per hour. The number of fetal movements in 12 hours can also be multiplied by 4. If the 12 hour fetal movement reaches more than 30 times, it reflects that the fetal condition is good, less than 20 times, indicating that the fetus is abnormal. If the fetal movement is less than 10 times, it indicates that the fetus is intrauterine hypoxia.

Fetal growth can be measured by the height of the uterine fundus (distance from the top of the pubic symphysis to the highest part of the uterine fundus). Under normal circumstances, after 28 weeks of pregnancy should be increased by about 1 cm per week. Pregnant women can be regularly measured at home or to the hospital. If there is no increase for 2 weeks, further examination should be done.

The routine detection of fetal heart rate in the third trimester of pregnancy has a certain value for the detection of fetal distress. However, in clinical practice, many fetal distress often shows that the fetal heart rate is in the normal range. When the fetal movement is reduced, the acceleration after fetal movement is not obvious, and the fetal heart rate variability is reduced, even if the fetal heart rate is in the normal range, fetal distress should be diagnosed; On the contrary, only abnormal fetal heart rate, fetal movement, fetal heart rate monitoring, B-ultrasound monitoring and other indicators are normal, it is not necessarily fetal distress, so when fetal heart rate auscultation found abnormal, if conditions permit, fetal heart rate monitoring should be performed; On the other hand, when there are many high-risk factors in the fetus, although the fetal heart rate is in the normal range, fetal heart rate monitoring should be carried out regularly. Only when the fetal heart rate auscultation is combined with clinical high-risk situation and other monitoring methods, can it play its value of early diagnosis.

matters needing attention

The husband can learn to listen to the fetal heart rate directly with a stethoscope under the guidance of the doctor. The normal fetal heart rate should be 120-160 beats / min. the fetal heart rate should increase more than 10 beats / min during fetal movement or the fetal heart rate is irregular. If the fetal heart rate slows down less than or more than this number, it indicates that the fetus is lack of oxygen and should go to the hospital in time.
