Abstract

OBJECTIVE

To examine the effect of vibroacoustic stimulation on fetal voiding as a measure of stress.

METHODS

Fetal bladder volumes were examined serially by ultrasound 5 and 1 minutes before and 1 and 5 minutes after vibroacoustic stimulation (21 cases) or sham stimulation (20 cases).

RESULTS

In the stimulated group, the mean (+/- SD) bladder volume decreased from 21.7 +/- 11.3 mL 1 minute before stimulation to 12.8 +/- 9.4 mL 1 minute after vibroacoustic stimulation, a statistically significant difference (P < .001). There was no significant decrease in bladder volume in the sham-stimulated fetuses. The correlations between bladder volume 1 minute before and 1 and 5 minutes after vibroacoustic stimulation were statistically significant (P < .01 and P < .001, respectively).

CONCLUSION

Vibroacoustic stimulation induces fetal voiding, which may reflect a response to stress.

摘要

目的

研究振动声学刺激对胎儿排尿的影响，以此作为一种应激指标。

方法

通过超声连续检测21例接受振动声学刺激及20例接受假刺激的胎儿在刺激前5分钟和1分钟、刺激后1分钟和5分钟时的膀胱容量。

结果

在刺激组中，平均（±标准差）膀胱容量从刺激前1分钟的21.7±11.3毫升降至振动声学刺激后1分钟的12.8±9.4毫升，差异具有统计学意义（P<.001）。假刺激胎儿的膀胱容量无显著下降。振动声学刺激前1分钟与刺激后1分钟和5分钟时膀胱容量的相关性具有统计学意义（分别为P<.01和P<.001）。
