Abstract

PurposeThe aim of this study was to assess the effect of hydration with oral water on non-stress test (NST).Design/methodology/approachThe study was conducted as single-blinded and randomized controlled. Healthy and outpatient 32- to 40-week pregnant women who were aged 19 and older were included in the study. Intervention group pregnant women (n = 66) drank 500 ccs of water before the NST, and no attempt was made to the control group (n = 66). The NST parameters of the groups with fetal heart rate (FHR), variability, acceleration, deceleration, reactivity and nonreactivity were evaluated.FindingsBoth groups were found to be similar in terms of their descriptive characteristics and variables related to pregnancy (p > 0.05). The median FHR was 130.0 in the intervention group, 140.0 in the control group (p < 0.001), and the median number of the acceleration was 6.0 in the intervention group and 4.0 in the control group (p < 0.001). In terms of the median number of decelerations, the groups were similar (p > 0.05).Originality/valueIt was found that hydration with oral water had an effect on NST parameters of FHR and the number of accelerations. However, it was observed that the FHR was within the normal range in both groups. It was thought that it tended to increase the number of accelerations.

Highlights

One of the important diagnostic tests applied in the prenatal period is the nonstress test (NST) [1]
While the average age of the pregnant women participating in the study was 26.62 ± 5.44 in the intervention group, it was 28.08 ± 5.32 in the control group
It was determined that 47.1% of the intervention group, 45.6% of the control group only completed primary education, 87.9% of the intervention group and 90.9% of the control group were unemployed

Summary

Introduction

One of the important diagnostic tests applied in the prenatal period is the nonstress test (NST) [1]. NST can be defined as recording fetal heart sounds using electronic fetal monitorization and tracking the relationship between fetal movements and heart rate [2]. The NST evaluates the well-being of the fetus by assessing the fetus using variability, acceleration, deceleration, fetal heart rate (FHR), reactivity and nonreactivity parameters [3]. In addition to being a painless test that does not require any invasive procedure, it is thought to be risk-free for both the mother and the fetus [4]. In a healthy pregnancy that continues normally, a healthy fetus is active during the pregnancy. With every movement of the fetus in the womb, an acceleration in FHR occurs. The fact that fetal heartbeats are accelerating during each activity that the fetus creates is an
