fetal heart rate monitoring

Fetal heart monitoring is the abbreviation of fetal heart movement and contraction. It is a graph that uses fetal heart rate electronic monitor to record fetal heart rate curve and contraction pressure waveform for clinical analysis. It is the main test for correct evaluation of fetal intrauterine status. means. Fetal heart monitoring is the use of ultrasound to monitor the condition of the fetus in the uterus, which is safe for the fetus. Basic Information Specialist classification: maternity check check classification: ultrasound Applicable gender: whether women are fasting: not fasting Tips: Pay attention to rest before check, eat properly or follow the doctor's advice to prevent fatigue. Normal value Fetal heart rate, under normal conditions, fluctuates between 120-160. Generally, the basal heart rate line appears as a wavy line. When the fetal movement occurs, the heart rate will rise, and a curve will appear upward. After the fetal movement ends, it will slowly drop. Counting >30 times/12 hours is normal, <10 times every 12 hours suggesting fetal hypoxia. The next one indicates intrauterine pressure, as long as it increases during contractions, it will remain around 20mmHg. Clinical significance Abnormal results The normal fetal heart rate is between 120 beats / min ~ 160 beats / min, if the fetal heart rate lasts more than 10 minutes are <120 / min or > 160 points, indicating fetal heart rate is abnormal. At present, the application of fetal heart rate monitor has become more popular. When the fetal heart is protected, it is found that there is abnormal fetal heart pattern, and it is often used to indicate abnormal fetal heart. Abnormal fetal heart rate in most cases means that the fetus has hypoxia in the uterus. The more severe the abnormal fetal heart rate, the more severe the fetal hypoxia is, but not all fetal heart abnormalities are caused by hypoxia. In addition, the pregnant woman's own situation also affects fetal heart rate changes, such as pregnant women with fever, fetal heart rate often exceeds 160 beats / min, pregnant women have hyperthyroidism, her own heart rate is very fast, the fetal heart rate often exceeds 160 beats / min If pregnant women take certain drugs, such as salbutamol taken during preterm birth, or use atopine, it can cause heart rate in mothers and children to accelerate. Slow fetal heart rate may be caused by fetal hypoxia, but sometimes pregnant women take certain drugs, such as propranolol, the drug acts on the fetus through the placenta, causing the fetal heart rate to slow down. When the fetal heart rate continues to be slow, pay attention to check the possibility of congenital heart disease in the fetus. In addition, after more than 40 weeks of pregnancy, the fetal heart may sometimes be less than 120 times due to the development of the fetal nervous system. Points, therefore, in the case of fetal heart abnormalities, it is necessary to carefully analyze the situation and make correct judgments and treatments. If there is indeed fetal hypoxia, early delivery should be made. Pregnant women in need to check and people who need to check fetal development. High results may be diseases: intrauterine distress, placental abruption, umbilical cord prolapse, uterine contraction fatigue considerations Taboo before the examination: poor rest, improper diet, excessive fatigue. Requirements for inspection: Actively cooperate with the doctor's work. Eat some food, such as chocolate, from 1.30 minutes to an hour ago. 2. Choose the most frequent time of fetal movement during the day to avoid unnecessary duplication. 3. Monitor in a comfortable position to avoid supine position. 4. During the monitoring process, the baby is not willing to move. He is most likely to fall asleep. You can gently shake your abdomen to wake him up. 5. The effect of fetal heart monitoring is not very satisfactory. For example, the condition of NST (±) is also likely to occur. The monitoring will continue to do. It is very possible to do 40 minutes or 1 hour. Please do not overdo it. Anxious. Inspection process Fetal heart monitoring is the use of ultrasound to monitor the condition of the fetus in the uterus, which is safe for the fetus. You can purchase the fetal heart rate detector yourself and use it according to the correct method of use to get the test results. You can also go to the hospital for testing. Not suitable for the crowd People who have poor rest, improper diet, and excessive fatigue. Adverse reactions and risks No complications.
