INTRODUCTION AND HYPOTHESIS
This time-series analysis was carried out to determine if the use of the EPISCISSORS-60®, episiotomy scissors specifically designed to achieve a cutting angle of 60°, would continue to sustain obstetric anal sphincter injuries (OASIS) reductions at our hospital 2 years after its introduction.
METHODS
We compared data from 2,342 women delivered in 2014 (prior to the introduction of EPISCISSORS-60®) with that of 4,498 women delivered from 2016 to 2017 (after the introduction of EPISCISSORS-60®).
RESULTS
There was a reduction of OASIS in all nulliparous vaginal deliveries (NVD; 7.2% vs 5.1% p = 0.05), and a 50% reduction of OASIS (7.5% vs 3.7%) in operative vaginal deliveries (OVD) (p = 0.02). There was a statistically significant association between episiotomies performed with EPISCISSORS-60® and a reduction in OASIS (SVD: 6.9% vs 1.5% p = 0.006; OVD:28.6% vs 2.6% p < 0.0001). Additionally, there was an increase in the use of episiotomies in all nulliparous vaginal deliveries (29% vs 33.7%; p = 0.01). We also found a 78% reduction of OASIS with episiotomies compared with no episiotomies in the 2016-2017 group (6.9% vs 1.5% p = 0.006).
CONCLUSIONS
Our results suggest that there might have been a sustained reduction in OASIS rates associated with using EPISCISSORS-60®.
引言和假设
本时间序列分析旨在确定在引入 EPISCISSORS-60 ® 特定设计的侧切剪以实现 60°侧切角度后，我们医院是否会继续降低产科肛门括约肌损伤 (OASIS) 的发生率。
方法
我们比较了 2014 年（在 EPISCISSORS-60 ® 引入之前）2342 名产妇和 2016 年至 2017 年（在 EPISCISSORS-60 ® 引入之后）4498 名产妇的数据。
结果
所有初产妇的阴道分娩 (NVD) 中 OASIS 发生率降低（7.2%比 5.1%，p=0.05），阴道助产分娩 (OVD) 中 OASIS 发生率降低 50%（7.5%比 3.7%，p=0.02）。使用 EPISCISSORS-60 ® 行会阴切开术与 OASIS 发生率降低显著相关（SVD：6.9%比 1.5%，p=0.006；OVD：28.6%比 2.6%，p<0.0001）。此外，在所有初产妇的阴道分娩中，会阴切开术的使用率增加（29%比 33.7%，p=0.01）。我们还发现，与 2016-2017 年组中无会阴切开术相比，会阴切开术的 OASIS 发生率降低了 78%（6.9%比 1.5%，p=0.006）。
结论
我们的结果表明，使用 EPISCISSORS-60 ® 可能会持续降低 OASIS 发生率。
