Summary

The objective of this study was to assess the effects of different maternal positions during electronic fetal monitoring (EFM) on maternal and fetal health outcomes. The study was conducted between December 2021 and January 2023 in a maternity hospital in Istanbul, employing a randomized controlled trial design. A total of 240 pregnant women were randomized into three groups: 60 participants were assigned to the right-side lying position (intervention 1), 60 to the semi-sitting position (intervention 2), and 120 to the left-side lying. Maternal systolic blood pressure, body temperature, and pulse rate were measured before, during, and after the EFM procedure. Research data were collected through the Information Form and the General Comfort Scale-Short Form.
