Fetal response to maternal sleep position

Study Aim Our primary aim is to determine the fetal heart response to maternal sleep position during late pregnancy. We will establish if there is an association between maternal sleep position and fetal well-being as determined by fetal heart rate and heart rate variability. We will also conduct a logistic regression analysis of fetal monitoring outcomes by modelling other risk factors, such as maternal sleep stage and state, weight, fetal biometry, Doppler studies and placental location to explore associations that may be useful in hypothesis generation.
Study Design/Methods Observational Cohort
Countries of Recruitment Australia
Target number of participants
Short synopsis This pilot study will examine fetal heart rate responses to maternal sleep position in a near term, pregnant population. The aim of this pilot study is to test the feasibility of studying the fetal heart rate as pregnant women sleep, to determine the process needed to accurately record fetal well being during a maternal sleep study, as well as provide pilot data on which to base valid power calculations for future studies.We will monitor the mother using PSG and her unborn baby overnight via continuous fetal monitoring to investigate fetal heart rate response to maternal sleep position. We hypothesize that certain maternal sleep positions will be associated with a fetal stress response including, drop in heart rate from baseline, heart rate decelerations and/or loss of heart rate variability. This study will provide important first information on fetal response to maternal sleep position. It will also facilitate future studies by providing data on which to base further funding. We anticipate that this study could lead to results that both improve pregnancy outcomes and lead to development of perinatal guidelines and practices to improve pregnancy care.
