AimWe的目的是探讨成功的预测因素头外倒转术（ECV）使用区域anesthesions.MethodsIn这项回顾性研究中，我们包括妇女谁接受了ECV在我们的中心，从2010年至2022年。该手术采用区域麻醉和静脉注射盐酸利托君进行。主要结局是ECV的成功，其定义为从非头位到头位的旋转。主要暴露是母体人口统计学因素和ECV超声检查结果。为了确定预测因素，我们进行了Logistic回归分析。ResultsOf 622孕妇谁接受ECV，任何变量（n= 14）缺失的数据被排除在外，其余608进行了分析。研究期间的成功率为76.3%。经产妇女的成功率显著高于非经产妇女（调整后的比值比[OR]：2.06 [95%置信区间（CI）：1.31-3.25]）。最大垂直囊袋（MVP）<4 cm的女性成功率显著低于4 cm < MVP ≤6 cm的女性（OR：0.56 [95% CI：0.37-0.86]）。非前胎盘位置的成功率高于前胎盘位置（OR：1.46 [95%CI：1.00-2.17]）。这三个因素可能有助于选择成功ECV的患者。
AimWe aimed to investigate predictive factors of successful external cephalic version (ECV) using regional anesthesia.MethodsIn this retrospective study, we included women who underwent ECV at our center from 2010 to 2022. The procedure had been conducted using regional anesthesia and the administration of intravenous ritodrine hydrochloride. The primary outcome was the success of ECV, which was defined as the rotation from a non‐cephalic to a cephalic presentation. Primary exposures were maternal demographic factors and ultrasound findings at ECV. To determine predictive factors, we conducted a logistic regression analysis.ResultsOf 622 pregnant women who underwent ECV, missing data on any variables (n= 14) were excluded and the remaining 608 were analyzed. The success rate during the study period was 76.3%. Multiparous women had significantly higher success rates than primiparous women (adjusted odds ratio [OR]: 2.06 [95% confidence interval (CI): 1.31–3.25]). Women with a maximum vertical pocket (MVP) of <4 cm had significantly lower success rates than those with 4 cm < MVP ≤6 cm (OR: 0.56 [95% CI: 0.37–0.86]). The non‐anterior placental location was associated with higher success rates than the anterior placental location (OR: 1.46 [95% CI: 1.00–2.17]).ConclusionsMultiparity, MVP >4 cm, and non‐anterior placental locations were associated with successful ECV. These three factors could be useful for patient selection for successful ECV.
