Most babies who measure small during pregnancy are born healthy. However, some are small
because they are not growing as expected, usually because the placenta (the baby's 'life
support' system) is not working properly. These babies are at greatly increased risk of
dying before birth, and need to be delivered before they become poorly.
Scans and electronic heartrate monitoring are currently used to monitor these babies. But
they can only be used for short periods and don't always provide enough information to show
when to deliver the baby.
A small light monitor has been developed that safely records the baby's heart rate for up to
16hrs by measuring electrical activity through sticky patches on the mum's skin (like a
normal ECG). The woman carries on with her daily activities while wearing it. Monitoring the
heart rate over a longer time may help with decisions about the timing of the delivery and
could prevent stillbirth, the aim of our future study. This will include large numbers of
women carrying small babies. Before the investigators can do this the investigators need to
know whether:
1. Wearing the monitor for 16hrs is practical and acceptable to pregnant women
2. The monitor can provide useful information on the baby's heart rate at different stages
of pregnancy.
Thirty pregnant women whose babies are measuring small will be asked to wear the monitor on
two occasions, for 16hrs each time. The women will describe what they think about wearing
the monitor by completing questionnaires.
The data from the monitor will be downloaded and compared with the woman's medical notes
after the participant has delivered her baby. Results from this study will be publicised and
will help with the design of the investigators future study into the usefulness of this
monitor.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | To assess recruitment rate to the study on first invitation | one year | ||
Primary | To estimate proportion of recruited women who demonstrate willingness to wear the monitor two times | In light of investigator's previous work, no problems are anticipated in achieving 30 recruits in a year. However, study would be deemed successful if at least 80% of participants wear the monitor on second occasion and complete the study | one year | |
Secondary | To measure success rate of fetal heart rate data across different stages of pregnancy | Success rate will be presented in percentage. | one year |
