The tool for tocotransducer monitoring is the tocotransducer monitor, which can be formed by the principle of ultrasonic Doppler and the change of fetal heartbeat current. The tocotransducer monitor is a measuring instrument used to detect the fetal heart rate and trace the uterine contraction. In addition, it can also reflect the graphics of the fetal heartbeat activity. It is one of the most common ways to monitor the intrauterine status of pregnant women.
1. The tocotransducer monitor can detect changes in fetal heart rate and uterine pressure
The change of the fetal heart is the manifestation of the normal development of the fetal central nervous system, which can very intuitively show the reserve capacity and health of the fetus in the abdomen. The electronic tocotransducer monitor can continuously detect changes in fetal heart rate and uterine pressure, and can provide real-time information between fetal heart rate and labor force. Compared with manual auscultation, it will not be affected by uterine contractions, and instantaneous fetal heart rate changes can be viewed.
Doctors can obtain timely and accurate information from the fetal heart rate baseline and different monitoring graphics, so that they can not only evaluate the real-time situation of the fetus, provide a basis for dystocia treatment, but also detect the fetal reserve function and whether it will occur. Symptoms such as severe umbilical cord entanglement. At the same time, tocotransducer monitoring has a certain predictive value for the tolerance of vaginal delivery. Therefore, electronic fetal heart rate monitoring has the advantages of fast, convenient, clear, and high accuracy, and is relatively easy for pregnant women to accept. It is one of the important measures to improve the quality of obstetrics, and it is worth trying and using by pregnant women.
Ⅱ. The tocotransducer monitor can monitor the baby's condition in time
During the production process, abnormal CTG in various periods can be used as a signal of intrauterine hypoxia. However, CTG itself still has a false positive rate of 25% to 50%, which may affect the status of fetal placental function. At present, obstetricians are looking for new detection methods to be used together with CTG to monitor the actual condition of the fetus.
The most common ones are fetal scalp pH measurement, amniotic fluid monitoring, B-ultrasound biophysical score, arterial blood flow velocity test and so on. Many medical experts believe that the most reliable method of tocotransducer monitoring during labor is a combination of CTG and biochemical testing. The purpose of this is to discover and identify whether CTG is abnormal and whether the fetus is hypoxic, thereby reducing the false positive rate of CTG, eliminating unnecessary obstetric intervention, and reducing fetal mortality and the probability of early neonatal illness.
The coincidence rate of CTG predicting that the fetus is in good condition is much higher than that of predicting fetal problems. When CTG is positive, other data should be referred to at the same time, such as whether the amniotic fluid is contaminated, the age of the pregnant woman, the pregnancy cycle, etc. The progress of the production process and the data of B-ultrasound monitoring should be considered to make the best treatment plan.
