To examine the effect of a nurse-driven intervention using a peanut ball (PB) with position changes on length of labor and incidence of cesarean birth among women who receive epidural anesthesia.
Quasiexperimental comparison group design.
SETTING/LOCAL PROBLEM: A 407-bed, nonprofit, Magnet-designated, Baby-Friendly Hospital Initiative-designated hospital with 8 labor and delivery suites and an average of 100 births per month.
A total of 343 participants were included, with 164 women in the PB group.
INTERVENTION/MEASUREMENTS: The PB was placed after epidural administration; women were repositioned a minimum of every 1 to 2 hours, and the PB was removed at second stage of labor; duration was recorded.
Overall, women in the PB group were 50% less likely to have cesarean birth. For women with cervical dilation of 4 cm or less, rates of vaginal birth were 61% with use of the peanut ball. A multivariate analysis of outcomes was used. A multiple linear regression model showed, after adjusting for other variables, that PB placement alone did not shorten labor length (p = .4684). However, a stratified analysis indicated that for women with cervical dilation of 4 cm or less, length of the first stage of labor was affected by parity (p = .0042) and frequency of position change (p < .001). For women with cervical dilation greater than 4 cm, length of the first stage of labor was influenced by frequency of position changes (p = .0130) and effacement (p = .0050). Length of the second state of labor was affected by the frequency of position change (p = .0416).
The PB may be an effective intervention to reduce the incidence of cesarean birth. Changing position frequently was associated with reduced length of first and second stages of labor.
探讨在接受硬膜外麻醉的产妇中,采用花生球(PB)并配合体位改变的护士主导干预措施对产程及剖宫产发生率的影响。
准实验性对照组设计。
地点/当地问题:一家拥有407张床位的非营利性、获得磁铁认证、符合爱婴医院倡议标准的医院,设有8间分娩套房,每月平均分娩100例。
共纳入343名参与者,其中PB组有164名女性。
干预措施/测量指标:硬膜外给药后放置PB;产妇至少每1至2小时更换一次体位,第二产程时取出PB;记录产程时间。
总体而言,PB组产妇剖宫产的可能性降低了50%。对于宫颈扩张4厘米及以下的产妇,使用花生球时阴道分娩率为61%。采用多变量分析结果。多元线性回归模型显示,在调整其他变量后,单独放置PB并不能缩短产程(p = 0.4684)。然而,分层分析表明,对于宫颈扩张4厘米及以下的产妇,第一产程的时长受产次(p = 0.0042)和体位改变频率(p < 0.001)影响。对于宫颈扩张大于4厘米的产妇,第一产程时长受体位改变频率(p = 0.0130)和宫颈消退程度(p = 0.0050)影响。第二产程时长受体位改变频率影响(p = 0.0416)。
花生球可能是降低剖宫产发生率的有效干预措施。频繁改变体位与第一和第二产程时长缩短有关。
