Benefits and dangers of fetal monitors
Fetal mirror: this method is non-invasive, simple and easy to use, and there is a living person at the other end (this can prevent some mechanical errors. )。 This allows the mother to handle the mobility of her work, shower, etc. It needs to train people who use it, although it is a standard procedure and is taught in every medical and nursing institution. In high-risk situations, induction, or with certain drugs, it cannot provide all-weather monitoring, which may be necessary.
Doppler: This method can also be used intermittently, requiring little training, having a live person at the other end and keeping the mother moving. It may also be easier to use during contraction. The equipment does not use ultrasonic waves and does not provide the required continuous monitoring of high-risk labor.
Fetal electronic monitoring: this method takes into account the relationship between the baby's heart sound at each heartbeat and the mother's contractions. This can be used continuously or intermittently. This is a high-risk mother with interests, but a suspicious interest, a low-risk mother. This method takes advantage of the mechanical error of ultrasound leaving the room, which may lead to incorrect interpretation and unnecessary intervention. The mother's mobility loss (when using) may reduce childbirth; And can divert attention from the mother's machine.
Internal monitoring: This is a high-risk parturient, which is more accurate than electronic monitoring, and can provide continuous monitoring without using ultrasound. This method requires that your water be destroyed (if your water is destroyed artificially, it is still intact. ), then you are 2-3 cm dilated cardiomyopathy. Artificial membrane rupture increases its own risk. However, the risks and benefits of each process must be weighed. This type of monitoring is almost entirely in high-risk situations, or more accurate monitoring can prevent other unnecessary interventions. This type of monitoring is also accompanied by fetal injury (electrode), mother or baby infection and so on.
Telemetry monitoring: This is the "latest" monitoring function. It uses a radio transmitter to connect to your thigh and transmit the baby's heart rate to the nurse station. You keep your mobility and have continuous monitoring, but again, continuous monitoring of low-risk mothers is very doubtful.
What is fetal heart monitoring?
Fetal heart monitoring is the abbreviation of fetal heart contraction diagram, and it is the main detection method to correctly evaluate the intrauterine situation of fetus. Using electronic fetal heart monitor to monitor fetal heart can record the instantaneous change of fetal heart, and doctors can know the reaction of fetal heart during fetal movement and contraction in time through the signal curve of the instantaneous change of fetal heart, so as to infer whether the intrauterine fetus is hypoxic. Fetal heart refers to the heartbeat of the fetus. Generally, in the 12 weeks of pregnancy, the fetal heart can be heard with a stethoscope in the abdomen of the expectant mother.
Methods of monitoring fetal heart rate at home;
At present, there are three kinds: stethoscope, fetal heart and fetal speech instrument.
(1) Stethoscope is very common and cheap, but it is difficult for ordinary people to hear it when finding the position of fetal heart.
(2) Both fetal heart rate and fetal language instrument adopt Doppler auscultation technology. Fetal heart rate can be heard through fetal heart rate, and some can be displayed through LED or LCD screen.
(3) The fetal voice recorder is an intelligent device, which can basically meet the standard of monitoring fetal heart rate at home. It can be used to listen to and record fetal sounds, count heart rate and fetal movement, draw monitoring curves, and let doctors listen to fetal heart remotely. Need to connect with mobile phone applications, suitable for pregnant women to use Apple and Android phones.
