To determine the rate and factors associated with the successful Induction of Labor (IOL) in nulliparous patients undergoing scheduled IOL at 41 weeks of gestational age (GA) with an unfavorable cervix.
This was a retrospective analysis that included nulliparous patients who presented to the Labor and Delivery unit at the Bronx Lebanon Hospital Center between 2011 and 2012 for elective IOL at 41 weeks of GA. The Bishop score was assessed upon admission and IOL agents were used in compliance with ACOG guidelines in different combinations, based on the obstetrical team preference.
Labor and Delivery Unit of the Bronx Lebanon Hospital.
Nulliparous patients with 41 weeks of pregnancy for elective induction of labor.
Seventy-six patients were included in the study. GA was confirmed using a combination of the last menstrual period and a dating sonogram during pregnancy.
This was a retrospective chart review that included nulliparous patients who presented to the Labor and Delivery unit at the Bronx Lebanon Hospital Center between October 2011 and October 2012 for elective IOL at 41 weeks of gestational age with an unfavorable cervix defined as a Bishop score of 6 or less.
The overall successful rate of IOL in a combination of different maternal factors with different agents for induction in nulliparous patients undergoing scheduled IOL with an unfavorable Bishop score at 41 weeks of GA was 51.32 %.
Factors associated with successful IOL were younger age [22.3 years vs. 25.1(p = 0.015)], lower BMI [25 vs. 28.1(p = 0.46)] and lower maternal weight [64.75 kg vs. 74.02 (p = 0.28)]. Maternal height was not a contributing factor; the artificial rupture of membranes, epidural anesthesia and the prostaglandins used did not contribute. Use of cervical balloon and oxytocin was associated with failed IOL.
Patients undergoing IOL at 41 weeks with an unfavorable cervix had a successful rate of 51.32 %. Younger maternal age, lower weight, and lower BMI were associated with successful IOL.
确定在 41 孕周时宫颈条件不佳行计划性引产的初产妇引产成功率及其相关影响因素。
这是一项回顾性分析，纳入了 2011 年至 2012 年期间因 41 孕周行计划性引产而入住 Bronx Lebanon 医院产房的初产妇。入院时评估 Bishop 评分，并根据产科团队的偏好，遵循 ACOG 指南，使用不同药物组合。
Bronx Lebanon 医院产房。
41 孕周，计划行引产的初产妇。
共纳入 76 例患者。GA 由末次月经和孕期超声检查联合确定。
这是一项回顾性病历分析，纳入了 2011 年 10 月至 2012 年 10 月期间因 41 孕周行计划性引产而入住 Bronx Lebanon 医院产房的初产妇。宫颈条件不佳定义为 Bishop 评分＜6 分。
不同药物联合不同产妇因素在 41 孕周行计划性引产时对宫颈条件不佳的初产妇引产的总成功率。
成功引产的相关因素包括：年龄较小（22.3 岁 vs. 25.1 岁，p = 0.015）、BMI 较低（25 vs. 28.1，p = 0.46）、体重较轻（64.75kg vs. 74.02kg，p = 0.28）。产妇身高无影响因素；人工破膜、硬膜外麻醉和使用的前列腺素无影响；宫颈球囊和催产素的使用与引产失败相关。
宫颈条件不佳行引产的初产妇引产成功率为 51.32%。产妇年龄较小、体重较轻、BMI 较低与引产成功相关。
