Pregnancy Clinical Trial
Official title:
The Effect of Pressure Exerted on the Maternal Abdominal Wall by the Ultrasound Probe on Fetal Heart Rate
The aim of the study is to assess the change of fetal heart rate in response to the amount of pressure exerted on the maternal abdomen. The amount of pressure will be quantified using an electronic pressure sensor (FSR 400- Round Force Sensor, Interlink).
Previous studies have shown a fetal cardiovascular effect to the pressure exerted on the
maternal abdomen. Our null hypothesis is that there is a correlation between fetal heart
rate changes and pressure exerted on the fetus through the maternal abdomen.
Women at term pregnancy coming for a routine cardiotocography monitor, will undergo 5
minutes of quantified pressure on their abdomen, using the electronic pressure sensor. The
amount of pressure will be recorded as well as the fetal heartbeat baseline and changes to
the heart rate following the application of pressure.
