Abstract

Introduction

This study evaluated the effect of the noise level of the nonstress test (NST) device on stress parameters in primigravid women.

Methods

A total of 44 pregnant women participated in a randomized clinical trial between February and October, 2021. The participants were divided randomly into 4 equal groups using an automated web-based randomization system and ensuring allocation concealment: the control group (NST device volume turned off), intervention group I (1-35 dB(A)), intervention group II (36-60 dB(A)), and intervention group III (61 dB(A) and above). A data collection form was used to record personal information and stress parameters. Stress parameters (blood pressure, heart rate, oxygen saturation [SpO₂], blood glucose, salivary cortisol, and salivary adrenocorticotropic hormone [ACTH]) levels were measured pretest (0-2 minutes before NST starts), midtest (at 10 minutes of the NST), and posttest (within 0-2 minutes after NST was finished). The study was registered at ClinicalTrials.gov (identifier: NCT05488704).

Results

NST sound levels above 35 dB(A) increased the average cortisol and ACTH levels in the posttest. NST sound levels were positively correlated with posttest cortisol (r = .448) and posttest glucose (r = .302). There was interaction effect on heart rate, glucose, and cortisol level by time, indicating that the intervention groups experienced a significant acceleration in heart rate, glucose, and cortisol level after a noise intervention compared with the control group.

Discussion

Midwives should continue applying NST below 36 dB(A), considering the factors that may induce stress during the NST process.

非压力设备噪音水平对初产妇压力参数的影响：随机对照试验

简介：本研究评估了无压力测试（NST）装置的噪音水平对初产妇压力参数的影响：本研究评估了无应激测试（NST）装置的噪音水平对初产妇应激参数的影响：共有 44 名孕妇参加了 2021 年 2 月至 10 月期间的随机临床试验。参与者被随机分为 4 组，每组人数相等，采用基于网络的自动随机系统并确保分配隐藏：对照组（关闭 NST 装置音量）、干预 I 组（1-35 dB(A)）、干预 II 组（36-60 dB(A)）和干预 III 组（61 dB(A) 及以上）。数据收集表用于记录个人信息和压力参数。应激参数（血压、心率、血氧饱和度[SpO2]、血糖、唾液皮质醇和唾液促肾上腺皮质激素[ACTH]）水平分别在测试前（NST 开始前 0-2 分钟）、测试中（NST 开始 10 分钟时）和测试后（NST 结束后 0-2 分钟内）进行测量。该研究已在 ClinicalTrials.gov 上注册（标识符：NCT05488704）：结果：NST声级高于35 dB(A)会增加后测中皮质醇和促肾上腺皮质激素的平均水平。NST 声级与测试后皮质醇（r = .448）和测试后葡萄糖（r = .302）呈正相关。心率、血糖和皮质醇水平与时间存在交互效应，表明与对照组相比，干预组在噪音干预后心率、血糖和皮质醇水平明显加快：讨论：考虑到在 NST 过程中可能诱发应激的因素，助产士应继续将 NST 的噪音控制在 36 分贝（A）以下。
