The second stage of labor requires active patient engagement. Previous studies suggest that coaching can influence the second stage of labor duration. However, a standardized education tool has not been established, and patients face many barriers to accessing childbirth education before delivery.
This study aimed to investigate the effect of an intrapartum video pushing education tool on the second stage of labor duration.
This was a randomized controlled trial of nulliparous patients with singleton pregnancies ≥37 weeks of gestation admitted for induction of labor or spontaneous labor with neuraxial anesthesia. Patients were consented on admission and block randomized in active labor to 1 of 2 arms in a 1:1 ratio. The study arm viewed a 4-minute video before the second stage of labor on what to anticipate in the second stage of labor and pushing techniques. The control arm received the standard of care: bedside coaching at 10 cm dilation from a nurse or physician. The primary outcome was second stage of labor duration. The secondary outcomes were birth satisfaction (using the Modified Mackey Childbirth Satisfaction Rating Scale), mode of delivery, postpartum hemorrhage, clinical chorioamnionitis, neonatal intensive care unit admission, and umbilical artery gases. Of note, 156 patients were needed to detect a 20% decrease in the second stage of labor duration with 80% power, 2-sided alpha level of .05, and 10% loss after randomization. Funding was provided by the Lucy Anarcha Betsy award from the division of clinical research at Washington University.
Of 161 patients, 81 were randomized to standard of care, and 80 were randomized to intrapartum video education. Among these patients, 149 progressed to the second stage of labor and were included in the intention-to-treat analysis: 69 in the video group and 78 in the control group. Maternal demographics and labor characteristics were similar between groups. The second stage of labor duration was statistically similar between the video arm (61 minutes [interquartile range, 20-140]) and the control arm (49 minutes [interquartile range, 27-131]) (P=.77). There was no difference in mode of delivery, postpartum hemorrhage, clinical chorioamnionitis, neonatal intensive care unit admission, or umbilical artery gases between groups. Although the overall birth satisfaction score on the Modified Mackey Childbirth Satisfaction Rating Scale was similar between groups, patients in the video group rated their "level of comfort during birth" and "attitude of the doctors in birth" significantly higher or more positively than patients in the control group (P<.05 for both).
Intrapartum video education was not associated with a shorter second stage of labor duration. However, patients who received video education reported a higher level of comfort and a more favorable perception of their physician, suggesting that video education may be a helpful tool to improve the birth experience.
第二产程需要产妇积极参与。既往研究表明,指导可影响第二产程的持续时间。然而,尚未建立标准化的教育工具,并且患者在分娩前获取分娩教育方面面临许多障碍。
本研究旨在探讨产程中推送视频教育工具对第二产程持续时间的影响。
这是一项针对单胎妊娠≥37 孕周、行引产或自然临产且接受脊麻的初产妇的随机对照试验。患者入院时同意参与,并在活跃分娩时按 1:1 的比例随机分为主动干预组和对照组。研究组在进入第二产程前观看时长为 4 分钟的视频,内容为第二产程的预期情况和用力技巧。对照组接受标准的护理:从护士或医生那里获得第二产程 10cm 扩张时的床边指导。主要结局为第二产程持续时间。次要结局为分娩满意度(采用改良 Mackey 分娩满意度评分量表)、分娩方式、产后出血、临床绒毛膜羊膜炎、新生儿重症监护病房入院和脐动脉血气。值得注意的是,需要 156 名患者才能在 80%的效能下检测到第二产程持续时间减少 20%,双侧α水平为.05,随机分组后有 10%的失访。资金由华盛顿大学临床研究部的 Lucy Anarcha Betsy 奖提供。
在 161 名患者中,81 名被随机分配至标准护理组,80 名被随机分配至产程中视频教育组。这些患者中,有 149 名进入第二产程并纳入意向治疗分析:视频组 69 名,对照组 78 名。产妇的人口统计学和分娩特征在两组间相似。视频组的第二产程持续时间(61 分钟[四分位间距,20-140])与对照组(49 分钟[四分位间距,27-131])无统计学差异(P=.77)。两组间分娩方式、产后出血、临床绒毛膜羊膜炎、新生儿重症监护病房入院或脐动脉血气均无差异。虽然改良 Mackey 分娩满意度评分量表的总体分娩满意度评分相似,但视频组的“分娩时舒适度”和“医生在分娩中的态度”评分显著高于对照组(均 P<.05)。
产程中视频教育与第二产程持续时间缩短无关。然而,接受视频教育的患者报告其舒适度更高,对医生的态度更满意,这表明视频教育可能是改善分娩体验的有用工具。
