Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

IIntroduction: Electronic fetal monitoring (EFM) is widely utilized for pregnancy and labor management due to its non-invasive nature, ease of use, and accessibility. However, the accuracy of EFM outcomes may be influenced by various factors, including the maternal position during monitoring, maternal comfort, and maternal blood pressure. This study aimed to explore how different positions during EFM influence both maternal.

Objective: The primary objective of this study was to examine the effects of three different maternal positions during EFM-right-side lying, semi-sitting, and left-side lying-on maternal and fetal health parameters. These parameters included systolic blood pressure, body temperature, pulse rate, and maternal comfort.

Methods:

A randomized controlled trial was conducted in a pregnancy follow-up outpatient clinic at a maternity hospital in Istanbul from December 2021 to January 2023. The study included 240 pregnant women, who were randomly assigned to one of three groups:

* Intervention 1 (right-side lying position) - 60 participants
* Intervention 2 (semi-sitting position) - 60 participants
* Control group (left-side lying position) - 120 participants Maternal physiological data were collected at three time points: pre-EFM, during EFM, and post-EFM. The General Comfort Scale-Short Form was used to assess maternal comfort. Statistical analyses were conducted to identify significant differences between groups and over time.

PARALLEL

The study was conducted in a pregnant follow-up outpatient clinic of a maternity hospital in Istanbul, between December 2021 and January 2023, in a randomized controlled experimental study design with two interventions and a control group. In the study, 60 participants were placed in the right side lying position (intervention 1), 60 participants in the semi-sitting position (intervention 2) and 120 participants in the left side lying position (control group), and the study was completed with a total of 240 pregnant women. Research data were collected through the Information Form and the General Comfort Scale-Short Form.
