This high-tech replacement for the ear trumpet is used to track the baby’s heartbeat. Electronic fetal monitoring (EFM) will be used routinely in all cases of high-risk pregnancies, but most mothers and babies don’t require it. You will have EFM if you are being induced or your labour is being accelerated for any reason, or if you have opted for epidural anaesthesia. Its main function is to give warning of fetal distress. If your doctors decide that you and your baby would be better off with EFM, try to see it as a source of reassurance. You can watch your baby’s heartbeat during labour and know that he is fine.
What it is
There are two kinds of electronic monitors, external and internal. An external monitor can be used early in labour and is sometimes used during pregnancy to check the baby’s well-being. The internal monitor is slightly more accurate. You will have belts strapped around your body and a tiny electrode will be clipped on to the baby’s head. Your contractions and the baby’s heartbeat are recorded on a printout (partogram). There is also a video screen that records the contractions and heartbeats as visible waves, punctuated by flashing lights.
During a contraction blood flow to the placenta is reduced for a few seconds, and your baby`s heart rate will dip. This is quite normal and the heart rate returns to baseline when the contraction passes. If the return to baseline is delayed, your baby may be distressed and action can be taken early to protect his well-being. The latest type of EFM, known as telemetry, uses radio waves and allows you to walk around because the baby’s monitor is attached to a transmitter strapped to your thigh. The older equipment confines you to a bed or chair.
How it is done
Your waters bag are broken when the cervix is about 5-6 cm {2-TA in) dilated and the electrode is applied to your baby’s head. In addition to the baby’s monitor, which picks up his heartbeat, a second monitor is placed between your baby and the uterine wall to measure the pressure and contractions
